SUMMARY

Technical Problem

Incidentally, in the bonding jig, in a case where a gap (clearance) is provided in a holding portion that holds a member in order to enhance the workability and the member is crimped onto the body of a stabilizer, the member is deformed and a part of the member enters the gap to spread out, which reduces the surface pressure on the body of the stabilizer. On the other hand, in a case where a space equivalent to the size of the member is formed as the holding portion, there is no clearance. Thus, it takes time and effort to attach and detach the member to and from the bonding jig, or the member cannot be appropriately attached or detached, which may reduce the workability. The bonding jig is required to ensure the surface pressure of each member of the bushing against the body portion of the stabilizer at the time of bonding, and not to reduce the workability at the time of installing the member on the jig or at the time of detaching the jig after bonding.

The present invention has been made in view of the above, and an object of the present invention is to provide a bonding jig and a bonding method which make it possible to prevent the reduction in workability while a damping member is reliably crimped onto a bonded member.

DESCRIPTION OF EMBODIMENTS

Hereinafter, modes for carrying out the present invention (referred to as “embodiments” below) will be described with reference to the accompanying drawings. Note that the drawings are schematic, and the relationship between the thickness and the width of each portion, the thickness ratio of each portion, and the like may be different from actual ones, and portions having different dimensional relationships and ratios are sometimes included between the drawings.

First Embodiment

FIG.1is a perspective view illustrating an example of a stabilizer manufactured in the first embodiment of the present invention.FIG.2is a diagram illustrating a configuration, in the vicinity of a bushing member, of the stabilizer illustrated inFIG.1. A stabilizer1is made of a metal or various fibers (for example, carbon fibers). The stabilizer1includes a body portion2having both ends bent and a central portion extending linearly, and a bushing member3attached to the body portion2.

The body portion2extends in a columnar shape, for example, a cylindrical shape, and both ends thereof are bent. The body portion2may be solid or hollow.

For example, in a case where the stabilizer1is provided in an automobile, one end of the stabilizer1is connected to one suspension of suspensions located at the left and right, and the other end of the stabilizer1is connected to the other suspension. At this time, each end is fixed to the suspension via a through hole. The stabilizer1is fixed also to the vehicle body via the bushing member3.

The stabilizer1is produced by processing a base material. For example, a columnar base material is bent, and then, both ends are pressurized to form a planar shape, and a through hole is formed at each end.

The bushing member3includes a bushing31and a bracket32.

The bracket32is attached to the vehicle body via a screw or the like to support the body portion2via the bushing31.

The bushing31is made using an elastic material such as rubber or an elastic resin, and functions as a damping member that reduces vibration or the like of the stabilizer1transmitted from a road surface or the like. The bushing31includes two members (a first member301and a second member302). The bushing31is formed by sandwiching the body portion2between the first member301and the second member302and bonding the first member301and the second member302to the body portion2.

Next, a bonding process of bonding the bushing31to the body portion2will be described with reference toFIG.3.FIG.3is a flowchart illustrating the flow of a bushing bonding process according to the first embodiment.

First, an adhesive is applied to the first member301and the second member302(Step S101: adhesive application process). In Step S101, the adhesive is applied to surfaces of the first member301and the second member302to be bonded to the body portion. After the adhesive is applied, the first member301and the second member302are subjected to a drying process. Then, the first member301and the second member302are set in a bonding jig. The bonding jig will be described later.

After the adhesive is applied, a heat treatment is applied to the bonded portion of the bushing31in the body portion2(Step S102: heat treatment process). In the heat treatment, for example, an IH coil is used to heat a region including the bonded portion of the bushing31in the body portion2. In the heat treatment, the body portion2is heated by applying heat for about several tens of seconds, for example. The temperature for the heat treatment is appropriately set according to the type of the bushing31or the adhesive.

Before the heat treatment, the body portion2may be subjected to a surface treatment for improving the adhesiveness by plasma treatment.

Then, the first member301and the second member302are set in the bonding jig, and a bushing assembly process is performed on the body portion2(Step S103: bushing assembly process). In the bushing assembly process, a load for crimping the first member301and the second member302onto the body portion2is applied by the bonding jig.

The order of the heat treatment process and the bushing assembly process may be reversed.

After the bonding jig is assembled to the body portion2, a crimping and holding process for bonding the bushing31to the body portion2is performed (Step S104: crimping and holding process). In the crimping and holding process, the assembled state is held for the time it takes to complete the bonding, for example. At this time, the body portion2and the bushing31are bonded to each other by the pressure and the heat of the body portion2. Examples of the bonding mode include vulcanization bonding.

Then, the bonding jig is removed from the bushing31, so that the stabilizer1in which the bushing31is fixed to the body portion2is obtained. The bracket32is attached to the bushing31.

Next, the bonding jig will be described with reference toFIGS.4to10.FIGS.4,6,7, and9are plan views for explanation of a configuration of a bonding jig for bonding a bushing to a body portion in the first embodiment.FIGS.5,8, and10are perspective views for explanation of a configuration of a bonding jig for bonding a bushing to a body portion in the first embodiment.FIGS.4to6are diagrams illustrating only a bonding jig.FIGS.7to10are diagrams illustrating a bonding jig to which first and second members of a bushing are attached.

A bonding jig10includes a first bonding member11and a second bonding member12. In the bonding jig10, the first member301and the second member302are cramped onto the body portion2by covering the first bonding member11with the second bonding member12. At this time, for example, an air cylinder is used to pressurize the first bonding member11and the second bonding member12.

The first bonding member11includes a bottom surface portion111on which the first member301is placed, a first wall portion112and a second wall portion113which are erected, with respect to the bottom surface portion111, from both ends of the bottom surface portion111, and coil springs114which bias the wall portions in directions away from the bottom surface portion111.

The second bonding member12includes a body portion121that holds the second member302, and a first wall portion122and a second wall portion123that are erected, with respect to the body portion121, from both ends of the body portion121.

Here, in a state where no load from the second bonding member12is placed on the first bonding member11, a distance between an outer wall of the first wall portion112and an outer wall of the second wall portion113is denoted by d1, a distance between an inner wall of the first wall portion122and an inner wall of the second wall portion123is denoted by d2, a distance between an inner wall of the first wall portion112and an inner wall of the second wall portion113is denoted by d3, and a width of the first member301is denoted by d4(seeFIG.7). The distance d1is greater than the distance d2, and the distance d3is greater than the width d4. In addition, the difference (d1−d2) between the distance d1and the distance d2is set to be substantially equal to the difference (d3−d4) between the distance d3and the width d4, for example. By setting the difference (d1−d2) and the difference (d3−d4) to be substantially equal, when the first bonding member11is covered with the second bonding member12, a distance between the inner wall of the first wall portion112and the inner wall of the second wall portion113is set to be substantially equal to the width d4, and the first wall portion112and the second wall portion113are brought into contact with or pressed into contact with the first member301.

In the bonding jig10, when the second bonding member12is placed on the first bonding member11(seeFIG.4), the first wall portion122and the second wall portion123come into contact with the first wall portion112and the second wall portion113, respectively, which moves the first wall portion112and the second wall portion113toward the bottom surface portion111. As a result, the distance (corresponding to the distance d3) between the first wall portion112and the second wall portion113is shortened. The contact portions of the first wall portions112and122and the second wall portions113and123each have a tapered shape formed by chamfering corner portions, and, at the time of contact, the first wall portion112and the second wall portion113can be moved while being accommodated in the second bonding member12. The tapered shape may be formed on at least one of the wall portions in contact with each other. For example, as long as one of the first wall portions112and122has a tapered shape, smooth operation can be achieved.

In a state where the first member301is attached to the first bonding member11and the second member302is attached to the second bonding member12(seeFIGS.7and8), when the body portion2is disposed between the first member301and the second member302and the second bonding member12is placed on the first bonding member11, the first member301is sandwiched and held by the first wall portion112and the second wall portion113while the body portion2is in contact with the first member301and the second member302(seeFIGS.9and10). At this time, immediately after the first member301and the second member302come into contact with each other, the first member301is sandwiched by the first wall portion112and the second wall portion113. However, the contact between the first member301and the second member302and the sandwiching of the first member301by the first wall portion112and the second wall portion113may be performed in the reverse order or at the same time.

The first wall portion112and the second wall portion113sandwich and hold the first member301, so that the first member301can be positioned. Further, the movement of the first wall portion112and the second wall portion113is caused by the contact to the second bonding member12; therefore, the relative positional relationship between the positions of the first wall portion112and the second wall portion113and the position of the second bonding member12can be fixed. This enables crimping the first member301and the second member302onto the body portion2while a relative misalignment between the position of the first member301held by the first bonding member11and the position of the second member302held by the second bonding member12can be controlled.

Further, when the bushing31is bonded to the body portion2and then the second bonding member12is removed from the first bonding member11, the first wall portion112and the second wall portion113move in directions away from each other by the biasing force of the coil springs114, which forms a gap between the first wall portion112and the first member301as well as between the second wall portion113and the first member301. The gaps allow the first member301to be easily removed from the first bonding member11.

The coil springs114are included in a switching mechanism that switches, in a space where the first bonding member11holds the first member301, between a first state in which a gap is formed between the first bonding member11and a part of the side surface of the first member301, which is continuous with the crimping surface with the second member302, and a second state in which the gap is filled to control the position of the first member301. In the first embodiment, the gap between the first member301and the first bonding member11is filled due to the movement of the first wall portion112and the second wall portion113.

In the first embodiment, when the constituent members of the bushing31are attached to and detached from the bonding members, a gap is provided between the first wall portion112and the first member301as well as between the second wall portion113and the first member301to enhance the workability. When the first member301and the second member302are crimped onto the body portion2, the first member301is sandwiched by the first wall portion112and the second wall portion113to fix the position, which enables crimping while misalignment of the crimping surfaces of the first member301and the second member302with respect to the body portion2is prevented. According to the first embodiment, it is possible to prevent the reduction in workability while the bushing31is reliably crimped onto the body portion2.

In the first embodiment, a configuration without the coil springs114is possible as long as the first wall portion112and the second wall portion113can move in directions away from each other under their own weights.

In the first embodiment, the example in which an adhesive is applied to the bushing31has been described, but the adhesive may be applied to the body portion2, or the adhesive may be applied to each of the bushing31and the body portion2.

Second Embodiment

Next, the second embodiment of the present invention will be described with reference toFIG.11.FIG.11is a plan view for explanation of a configuration of a bonding jig for bonding a bushing to a body portion in the second embodiment. The same portions as those of the bonding jig10according to the first embodiment are denoted by the same reference numerals.

A bonding jig10A according to the second embodiment includes a first bonding member11A and a second bonding member12A. In the bonding jig10A, the first member301and the second member302are cramped onto the body portion2by covering the first bonding member11A with the second bonding member12A.

The first bonding member11A includes the bottom surface portion111on which the first member301is placed, the first wall portion112and the second wall portion113which are erected, with respect to the bottom surface portion111, from both ends of the bottom surface portion111, and the coil springs114which bias the first wall portion112and the second wall portion113in directions away from the bottom surface portion111. In the first bonding member11A, holes112aand113aare formed in the first wall portion112and the second wall portion113, respectively. The holes112aand113aare bored from ends of the first wall portion112and the second wall portion113opposite to ends thereof connected to the bottom surface portion111. Each of the holes112aand113ahas a hole shape extending obliquely toward the outer wall.

The second bonding member12A includes a body portion124that holds the second member302, and a first pin125and a second pin126that extend from both ends of the body portion124. The first pin125and the second pin126extend opposite to each other depending on the inclination of the holes112aand113a.In the second embodiment, the first pin125, the second pin126, and the holes112aand113aconstitute a switching mechanism.

Here, in a state where no load from the second bonding member12A is placed on the first bonding member11A, a distance (corresponding to the distance d3) between the inner wall of the first wall portion112and the inner wall of the second wall portion113is set to be greater than the width (distance d4illustrated inFIG.7) of the first member301, and when the second bonding member12A is placed on the first bonding member11A, the distance between the inner wall of the first wall portion112and the inner wall of the second wall portion113is set to be substantially equal to the width d4.

In the bonding jig10A, when the second bonding member12A is placed on the first bonding member11A, the first pin125and the second pin126are inserted into the holes112aand113a,respectively. The first pin125and the second pin126slide on the wall surfaces of the holes112aand113ato move the first wall portion112and the second wall portion113toward the bottom surface portion111. As a result, the distance (corresponding to the distance d3) between the first wall portion112and the second wall portion113is shortened. As in the first embodiment, the change in distance enables fixing the positional relationship between the positions of the first wall portion112and the second wall portion113and the position of the second bonding member12, and enables the first member301to be easily attached to and detached from the first bonding member11.

As with the first embodiment, in the second embodiment, when the constituent members of the bushing31are attached to and detached from the bonding members, a gap is provided between the first wall portion112and the first member301as well as between the second wall portion113and the first member301to enhance the workability. When the first member301and the second member302are crimped onto the body portion2, the first member301is sandwiched by the first wall portion112and the second wall portion113to fix the position, which enables crimping while misalignment of the crimping surfaces of the first member301and the second member302with respect to the body portion2is prevented. According to the second embodiment, it is possible to prevent the reduction in workability while the bushing31is reliably crimped onto the body portion2.

Third Embodiment

Next, the third embodiment of the present invention will be described with reference toFIGS.12and13.FIGS.12and13are plan views for explanation of a configuration of a bonding jig for bonding a bushing to a body portion in the third embodiment. In the third embodiment, a configuration of a first bonding member will be described.

A first bonding member11B according to the third embodiment includes a bottom surface portion115on which the first member301is placed, a first wall portion116A and a second wall portion116B which are placed on the bottom surface portion115, and a first moving mechanism117A and a second moving mechanism117B which move the first wall portion116A and the second wall portion116B, respectively. In the first bonding member11B, the first wall portion116A and the second wall portion116B are provided so as to be movable in directions toward or away from each other. The first moving mechanism117A and the second moving mechanism117B correspond to a switching mechanism.

The first moving mechanism117A includes a fulcrum portion117afixed to the bottom surface portion115, an effort point portion117bto which a load from a second bonding member is applied, and an action portion117cthat moves the first wall portion116A depending on the load applied to the effort point portion117b.The fulcrum portion117aand the effort point portion117bare connected by a connecting member, and the effort point portion117band the action portion117care connected by a connecting member.

In the first moving mechanism117A, when a load in an arrow direction inFIG.12is applied to the effort point portion117b,the effort point portion117bmoves toward the bottom surface portion115. The movement of the effort point portion117bmoves the action portion117cin a direction away from the fulcrum portion117a.As a result, the first wall portion116A moves toward the second wall portion116B.

The second moving mechanism117B also has the same configuration as that of the first moving mechanism117A. In the second moving mechanism117B, when a load is applied to the effort point portion117b,the effort point portion117bmoves toward the bottom surface portion115. The movement of the effort point portion117bmoves the action portion117cin a direction away from the fulcrum portion117a.As a result, the second wall portion116B moves toward the first wall portion116A.

At this time, in a state where a load other than gravity is not applied, the first moving mechanism117A is configured to maintain the shape in a state where the first wall portion116A and the second wall portion116B are spaced from each other as illustrated inFIG.12. The first wall portion116A and the second wall portion116B are biased in directions away from each other by a biasing member (not illustrated).

The second bonding member may be any member as long as it can hold the second member302and abut on the effort point portion117bto apply a load. For example, the application is made possible by adjusting the positions of the first wall portion122and the second wall portion123of the second bonding member12and the positions of the first pin125and the second pin126of the second bonding member12A.

Here, in a state where no load from the second bonding member is placed on the first bonding member11B, a distance (corresponding to the distance d3) between an inner wall of the first wall portion116A and an inner wall of the second wall portion116B is set to be greater than the width (distance d4illustrated inFIG.7) of the first member301, and when the second bonding member is placed on the first bonding member11B, a distance between the inner wall of the first wall portion112and the inner wall of the second wall portion113is set to be substantially equal to the width d4.

In the bonding jig, when the second bonding member is placed on the first bonding member11B, the distance (corresponding to the distance d3) between the first wall portion116A and the second wall portion116B is shortened. As in the first embodiment, the change in distance enables fixing the positional relationship between the positions of the first wall portion116A and the second wall portion116B and the position of the second bonding member, and enables the first member301to be easily attached to and detached from the first bonding member11.

As with the first embodiment, in the third embodiment, when the constituent members of the bushing31are attached to and detached from the bonding members, a gap is provided between the first wall portion116A and the first member301as well as between the second wall portion116B and the first member301to enhance the workability. When the first member301and the second member302are crimped onto the body portion2, the first member301is sandwiched by the first wall portion116A and the second wall portion116B to fix the position, which enables crimping while misalignment of the crimping surfaces of the first member301and the second member302with respect to the body portion2is prevented. According to the third embodiment, it is possible to prevent the reduction in workability while the bushing31is reliably crimped onto the body portion2.

Fourth Embodiment

Next, the fourth embodiment of the present invention will be described with reference toFIGS.14and15.FIGS.14and15are plan views for explanation of a configuration of a bonding jig for bonding a bushing to a body portion in the fourth embodiment.

A first bonding member11C according to the fourth embodiment includes a bottom surface portion115on which the first member301is placed, the first wall portion116A and the second wall portion116B which are placed on the bottom surface portion115, and a first moving mechanism117C and a second moving mechanism117D which move the first wall portion116A and the second wall portion116B, respectively. The first moving mechanism117C and the second moving mechanism117D correspond to a switching mechanism.

The first moving mechanism117C includes a fulcrum portion117dfixed to the bottom surface portion115, an effort point portion117eto which a load from a second bonding member is applied, and an action portion117fthat moves the first wall portion116A depending on the load applied to the effort point portion117e.The fulcrum portion117dand the action portion117care connected by a connecting member117g.

In the first moving mechanism117C, when a load in an arrow direction inFIG.14is applied to the effort point portion117e,the effort point portion117emoves toward the bottom surface portion115. The effort point portion117emoves to come into contact with the connecting member117g,and pushes down the connecting member117g.The connecting member117grotates around the fulcrum portion117dto move the action portion117f.The action portion117fslides with respect to the first wall portion116A. As a result, the first wall portion116A moves toward the second wall portion116B.

The second moving mechanism117D also has the same configuration as that of the first moving mechanism117C. In the first moving mechanism117C, when a load is applied to the effort point portion117e,the effort point portion117emoves toward the bottom surface portion115. The movement of the effort point portion117eslides the action portion117fwith respect to the second wall portion116B. As a result, the second wall portion116B moves toward the first wall portion116A.

The second bonding member may be any member as long as it can hold the second member302and abut on the effort point portion117eto apply a load. For example, the application is made possible by adjusting the positions of the first wall portion122and the second wall portion123of the second bonding member12and the positions of the first pin125and the second pin126of the second bonding member12A. Alternatively, the effort point portion117emay be provided at an end of the second bonding member.

Here, in a state where no load from the second bonding member is placed on the first bonding member11C, a distance (corresponding to the distance d3) between the inner wall of the first wall portion116A and the inner wall of the second wall portion116B is set to be greater than the width (distance d4illustrated inFIG.7) of the first member301, and when the second bonding member is placed on the first bonding member11B, a distance between the inner wall of the first wall portion112and the inner wall of the second wall portion113is set to be substantially equal to the width d4.

In the bonding jig, when the second bonding member is placed on the first bonding member11C, the distance (corresponding to the distance d3) between the first wall portion116A and the second wall portion116B is shortened. As in the first embodiment, the change in distance enables fixing the positional relationship between the positions of the first wall portion116A and the second wall portion116B and the position of the second bonding member, and enables the first member301to be easily attached to and detached from the first bonding member11.

As with the first embodiment, in the fourth embodiment, when the constituent members of the bushing31are attached to and detached from the bonding members, a gap is provided between the first wall portion116A and the first member301as well as between the second wall portion116B and the first member301to enhance the workability. When the first member301and the second member302are crimped onto the body portion2, the first member301is sandwiched by the first wall portion116A and the second wall portion116B to fix the position, which enables crimping while misalignment of the crimping surfaces of the first member301and the second member302with respect to the body portion2is prevented. According to the fourth embodiment, it is possible to prevent the reduction in workability while the bushing31is reliably crimped onto the body portion2.

Fifth Embodiment

The same portions as those of the bonding jig10according to the first embodiment are denoted by the same reference numerals.

A bonding jig10B according to the fifth embodiment includes a first bonding member11D, a second bonding member12B, and a wedge13. In the bonding jig10B, when the second bonding member12B is placed on the first bonding member11D, the wedge13enters the first bonding member11D to crimp the first member301and the second member302onto the body portion2.

The first bonding member11D has a body portion115A in which a housing portion115afor accommodating the first member301is formed. The housing portion115aincludes a bottom surface115bon which the first member301is placed and a side surface115cextending obliquely in a direction of the expansion of the internal space with respect to the bottom surface115b.

The second bonding member12B has the body portion124that holds the second member302.

The wedge13has a first claw portion131and a second claw portion132extending in a conical shape. The first claw portion131and the second claw portion132are designed to be equal to the width (distance d4illustrated inFIG.7) of the first member301when entering the first bonding member11D. The wedge13(the first claw portion131and the second claw portion132) constitutes a switching mechanism.

Here, in a state where no load from the second bonding member12B is placed on the first bonding member11D, the shortest distance between the facing side surfaces115cis the distance between the ends continuous to the bottom surface115b,and is equal to the first member301. The shortest distance between the facing side surfaces115cis the distance between the ends continuous to the bottom surface115b,and is equal to the first member301(width d4). The longest distance between the facing side surfaces115cis a distance between the ends (openings) on the opposite side to the bottom surface115bside, and is greater than the width of the first member301(distance d4illustrated inFIG.7) (corresponding to distance d3).

In the bonding jig10B, when the second bonding member12B is placed on the first bonding member11D, the first claw portion131and the second claw portion132enter the housing portion115a.The first claw portion131and the second claw portion132are inserted into the housing portion115a,so that the distance (corresponding to the distance d3) between the wall surfaces in the housing portion115ais shortened. The change in distance enables fixing the positional relationship between the position of the first member301in the first bonding member11D and the position of the second member302in the second bonding member12, and enables the first member301to be easily attached to and detached from the first bonding member11.

As with the first embodiment, in the fifth embodiment, when the constituent members of the bushing31are attached to and detached from the bonding members, a gap is provided between the first member301and the housing portion115ato enhance the workability. When the first member301and the second member302are crimped onto the body portion2, the first member301is sandwiched by the first claw portion131and the second claw portion132to fix the position, which enables crimping while misalignment of the crimping surfaces of the first member301and the second member302with respect to the body portion2is prevented. According to the fifth embodiment, it is possible to prevent the reduction in workability while the bushing31is reliably crimped onto the body portion2.

The body portion118includes a first plate118band a second plate118cthat are provided at an open end of the housing portion118aand are rotatable about a corner of the housing portion118aas a fulcrum. The first plate118band the second plate118cmay be connected so as not to be detached from the body portion118, or may be separated from the body portion118. The first plate118band the second plate118cconstitute a switching mechanism.

The first plate118band the second plate118care inclined so that the outer sides thereof extend beyond the housing portion118ain a state where a load other than gravity is not applied, which allows the first member301to be easily housed. On the other hand, after the bonding process, the first plate118band the second plate118care pulled out, which creates a gap corresponding to the size of the plate thickness between the housing portion118aand the first member301, so that the first member301is easily pulled out from the housing portion118a.

The second bonding member may be any member as long as the second bonding member holds the second member302and does not interfere with the first plate118band the second plate118cwhen covering the first bonding member11E. For example, the application is made possible by adjusting the positions of the first wall portion122and the second wall portion123of the second bonding member12.

Here, in a state where no load from the second bonding member is placed on the first bonding member11E, the maximum distance d5between the first plate118band the second plate118cis greater than the width of the first member301(distance d4illustrated inFIG.7). Setting is so made that a distance d6between the first plate118band the second plate118cis substantially equal to the width d4when the first plate118band the second plate118care housed in the housing portion118a.

In the bonding jig, when the first plate118band the second plate118care accommodated in the housing portion118afrom an inclined state outside the housing portion118a,the distance between the first plate118band the second plate118cis shortened. As in the first embodiment, the change in distance enables fixing the positional relationship between the position of the first member301by the first plate118band the second plate118cand the position of the second member302of the second bonding member, and enables the first member301to be easily attached to and detached from the first bonding member11.

As with the first embodiment, in the sixth embodiment, when the constituent members of the bushing31are attached to and detached from the bonding members, a gap is provided between the housing portion118aand the first member301to enhance the workability. When the first member301and the second member302are crimped onto the body portion2, the first member301is sandwiched by the first plate118band the second plate118cto fix the position, which enables crimping while misalignment of the crimping surfaces of the first member301and the second member302with respect to the body portion2is prevented. According to the sixth embodiment, it is possible to prevent the reduction in workability while the bushing31is reliably crimped onto the body portion2.

A first bonding member11F according to the seventh embodiment includes a body portion119a,and a first holding portion119band a second holding portion119cformed by bending a plate-like member. The first holding portion119brotates around a shaft119d.The second holding portion119crotates around a shaft119e.The shafts119dand119eare fixed to the body portion119aand attached to bent portions of the respective holding portions. The first holding portion119band the second holding portion119caccommodate the first member301between portions (hereinafter, referred to as wall portions119fand119g) rising and extending from the body portion119a.The first holding portion119band the second holding portion119cconstitute a switching mechanism.

The first holding portion119band the second holding portion119care inclined so that the wall portions119fand119gextend outward in a state where a load other than gravity is not applied, which allows the first member301to be easily housed and taken out (seeFIG.18). On the other hand, when the first member301is placed, the first holding portion119band the second holding portion119crotate, and the wall portions119fand119gsandwich the first member301therebetween (seeFIG.19).

The second bonding member may be any member as long as the second bonding member holds the second member302and does not interfere with the first holding portion119band the second holding portion119cwhen covering the first bonding member11F. For example, the application is made possible by adjusting the positions of the first wall portion122and the second wall portion123of the second bonding member12.

Here, in a state where no load from the second bonding member is placed on the first bonding member11F, the maximum distance d7between the wall portions119fand119gis greater than the width of the first member301(distance d4illustrated inFIG.7). Setting is so made that a distance d8between the wall portions119fand119gis substantially equal to the width d4when the first member301is placed and the first holding portion119band the second holding portion119crotate.

In the bonding jig, when the first member301is placed by the first holding portion119band the second holding portion119cfrom a state in which the wall portions119fand119gare inclined in directions away from each other, the distance between the wall portions119fand119gis shortened. As in the first embodiment, the change in distance enables fixing the positional relationship between the position of the first member301by the first holding portion119band the second holding portion119cand the position of the second member302of the second bonding member, and enables the first member301to be easily attached to and detached from the first bonding member11.

In the eighth embodiment, a configuration of a first bonding member will be described.

A first bonding member11G according to the eighth embodiment includes a bottom surface portion111A on which the first member301is placed, a first wall portion112A and a second wall portion113A which are erected, with respect to the bottom surface portion111A, on the side of both ends of the bottom surface portion111A, and leaf springs114A which bias the wall portions in directions away from the bottom surface portion111A.

The leaf springs114A are included in a switching mechanism that switches, in a space where the first bonding member11G holds the first member301, between a first state in which a gap is formed between the first bonding member11G and a part of the side surface of the first member301, which is continuous with the crimping surface with the second member302, and a second state in which the gap is filled to control the position of the first member301. In the eighth embodiment, the gap between the first member301and the first bonding member11G is changed due to the movement of the first wall portion112A and the second wall portion113A.

The leaf spring114A has a central portion connected to the bottom surface portion111A and both ends connected to the first wall portion112A (or the second wall portion113A). The leaf springs114A bias the wall portions connected thereto in directions away from the bottom surface portion111A. The leaf springs114A are fixed to the bottom surface portion111A and the wall portion by screwing, welding, or the like.

The second bonding member may be any member as long as the second bonding member holds the second member302and comes into contact with the first wall portion112A and the second wall portion113A to move the first wall portion112A and the second wall portion113A toward the bottom surface portion111A when covering the first bonding member11G. For example, the application is made possible by adjusting the positions of the first wall portion122and the second wall portion123of the second bonding member12.

Here, in a state where no load from the second bonding member is placed on the first bonding member11G, a distance between the first wall portion112A and the second wall portion113A is greater than the width of the first member301(width d4illustrated inFIG.7). Setting is so made that the distance between the first wall portion112A and the second wall portion113A is substantially equal to the width d4when the second bonding member is attached to the first bonding member.

The first inclined portion141and the second inclined portion142extend obliquely downward as being away from the bottom surface portion111A. Therefore, the first wall portion112B and the second wall portion113B move in a direction away from the bottom surface portion111A under their own weights in a state where a load other than gravity is not applied. The first inclined portion141and the second inclined portion142are included in a switching mechanism that switches, in a space where the first bonding member11H holds the first member301, between a first state in which a gap is formed between the first bonding member11H and a part of the side surface of the first member301, which is continuous with the crimping surface with the second member302, and a second state in which the gap is filled to control the position of the first member301.

The second bonding member may be any member as long as the second bonding member holds the second member302and comes into contact with the first wall portion112B and the second wall portion113B to move the first wall portion112B and the second wall portion113B toward the bottom surface portion111A when covering the first bonding member11H. For example, the application is made possible by adjusting the positions of the first wall portion122and the second wall portion123of the second bonding member12.

At this time, in response to the second bonding member attached, the first wall portion112B and the second wall portion113B rise along the first inclined portion141and the second inclined portion142, respectively, and approach the bottom surface portion111A. When the second bonding member is removed, the first wall portion112B and the second wall portion113B fall along the first inclined portion141and the second inclined portion142, respectively, under their own weights so as to be away from the bottom surface portion111A.

Here, in a state where no load from the second bonding member is placed on the first bonding member11H, a distance between the first wall portion112B and the second wall portion113B is greater than the width of the first member301(width d4illustrated inFIG.7). Setting is so made that the distance between the first wall portion112B and the second wall portion113B is substantially equal to the width d4when the second bonding member is attached to the first bonding member.

As with the first embodiment, in the ninth embodiment, when the constituent members of the bushing31are attached to and detached from the bonding members, a gap is provided between the first wall portion112B and the first member301as well as between the second wall portion113B and the first member301to enhance the workability. When the first member301and the second member302are crimped onto the body portion2, the first member301is sandwiched by the first wall portion112B and the second wall portion113B to fix the position, which enables crimping while misalignment of the crimping surfaces of the first member301and the second member302with respect to the body portion2is prevented. According to the ninth embodiment, it is possible to prevent the reduction in workability while the bushing31is reliably crimped onto the body portion2.

Tenth Embodiment

Next, the tenth embodiment of the present invention will be described with reference toFIG.23.FIG.23is a plan view for explanation of a configuration of a bonding jig for bonding a bushing to a body portion in the tenth embodiment. In the tenth embodiment, a configuration of a first bonding member will be described.

A first bonding member111according to the tenth embodiment includes a bottom surface portion111B on which the first member301is placed, a first wall portion112C and a second wall portion113C that are erected movably on the bottom surface portion111B, and a first magnetic portion143and a second magnetic portion144that generate force to move the wall portions.

The first wall portion112C and the second wall portion113C are made of a magnetic material.

The first magnetic portion143and the second magnetic portion144are configured using, for example, an electromagnet, and the energization thereto is controlled by a control device (not illustrated). Therefore, the first wall portion112C and the second wall portion113C move in a direction away from the bottom surface portion111A depending on a state in which the first magnetic portion143and the second magnetic portion144are energized. For example, when the first magnetic portion143and the second magnetic portion144are energized, the first wall portion112C and the second wall portion113C move in directions away from each other due to the magnetic force generated by the first magnetic portion143and the second magnetic portion144. The first magnetic portion143and the second magnetic portion144are included in a switching mechanism that switches, in a space where the first bonding member11I holds the first member301, between a first state in which a gap is formed between the first bonding member111and a part of the side surface of the first member301, which is continuous with the crimping surface with the second member302, and a second state in which the gap is filled to control the position of the first member301.

The second bonding member may be any member as long as the second bonding member holds the second member302and comes into contact with the first wall portion112C and the second wall portion113C to move the first wall portion112C and the second wall portion113C toward the bottom surface portion111B when covering the first bonding member111. For example, the application is made possible by adjusting the positions of the first wall portion122and the second wall portion123of the second bonding member12.

Note that, as long as the positions of the first wall portion112C and the second wall portion113C can be controlled by attaching the second bonding member, the first magnetic portion143and the second magnetic portion144may be constantly energized, or may be energized at necessary timing. In addition, as long as the movement of the first wall portion112C and the second wall portion113C can be controlled by magnetic force, the second bonding member without the first wall portion122and the second wall portion123is possible.

Here, in a state where no load from the second bonding member is placed on the first bonding member111, a distance between the first wall portion112C and the second wall portion113C is greater than the width of the first member301(width d4illustrated inFIG.7). Setting is so made that the distance between the first wall portion112C and the second wall portion113C is substantially equal to the width d4when the second bonding member is attached to the first bonding member.

As with the first embodiment, in the tenth embodiment, when the constituent members of the bushing31are attached to and detached from the bonding members, a gap is provided between the first wall portion112C and the first member301as well as between the second wall portion113C and the first member301to enhance the workability. When the first member301and the second member302are crimped onto the body portion2, the first member301is sandwiched by the first wall portion112C and the second wall portion113C to fix the position, which enables crimping while misalignment of the crimping surfaces of the first member301and the second member302with respect to the body portion2is prevented. According to the tenth embodiment, it is possible to prevent the reduction in workability while the bushing31is reliably crimped onto the body portion2.

The first screw portion145has a rod shape extending from the bottom surface portion111and penetrates the first wall portion112D. The first screw portion145is formed with a screw thread and is screwed to the first wall portion112D. Rotation of the first screw portion145around the longitudinal axis moves the first wall portion112D in the longitudinal axis direction. The moving direction of the first wall portion112D is determined depending on the rotating direction of the first screw portion145. The first screw portion145may be manually rotated by a user, or may be electrically rotated by a motor or the like. The second screw portion146extends from the bottom surface portion111in a direction opposite to the first screw portion145and penetrates the second wall portion113D. The second screw portion146is formed with a screw thread similarly to the first screw portion145, and rotates to move the second wall portion113D.

The first screw portion145and the second screw portion146are included in a switching mechanism that switches, in a space where the first bonding member11J holds the first member301, between a first state in which a gap is formed between the first bonding member11J and a part of the side surface of the first member301, which is continuous with the crimping surface with the second member302, and a second state in which the gap is filled to control the position of the first member301.

The second bonding member may be any member as long as the second bonding member holds the second member302and can bring the second member302into contact with the first member301held by the first bonding member11J when covering the first bonding member11J.

In the eleventh embodiment, when the second bonding member is attached, the first screw portion145and the second screw portion146are rotated to move the first wall portion112D and the second wall portion113D toward the bottom surface portion111. After the bonding process, the first screw portion145and the second screw portion146are rotated to move the first wall portion112D and the second wall portion113D in a direction away from the bottom surface portion111.

When the first member301is attached or detached, a distance between the first wall portion112D and the second wall portion113D is greater than the width of the first member301(width d4illustrated inFIG.7). Setting is so made that the distance between the first wall portion112D and the second wall portion113D is substantially equal to the width d4when the first member301and the second member302are attached to each other.

As with the first embodiment, in the eleventh embodiment, when the constituent members of the bushing31are attached to and detached from the bonding members, a gap is provided between the first wall portion112D and the first member301as well as between the second wall portion113D and the first member301to enhance the workability. When the first member301and the second member302are crimped onto the body portion2, the first member301is sandwiched by the first wall portion112D and the second wall portion113D to fix the position, which enables crimping while misalignment of the crimping surfaces of the first member301and the second member302with respect to the body portion2is prevented. According to the eleventh embodiment, it is possible to prevent the reduction in workability while the bushing31is reliably crimped onto the body portion2.

Twelfth Embodiment

Next, the twelfth embodiment of the present invention will be described with reference toFIG.25.FIG.25is a plan view for explanation of a configuration of a bonding jig for bonding a bushing to a body portion in the twelfth embodiment. In the twelfth embodiment, a configuration of a first bonding member will be described.

A first bonding member11K according to the twelfth embodiment includes a bottom surface portion111C on which the first member301is placed, the first wall portion112A and the second wall portion113A which are erected, with respect to the bottom surface portion111C, on the side of both ends of the bottom surface portion111C, and a link mechanism15that movably holds the wall portions.

The link mechanism15includes an operation portion151provided on the bottom surface portion111C, a first support portion152attached to the first wall portion112A, a second support portion153attached to the second wall portion113A, a first link154connecting the operation portion151and the first support portion152, and a second link155connecting the operation portion151and the second support portion153. In the link mechanism15, when the operation portion151is pushed against the bottom surface portion111C, the first support portion152and the second support portion153move in directions away from each other via the first link154and the second link155. This also moves the wall portions supported by the support portions.

The link mechanism15constitutes a switching mechanism that switches, in a space where the first bonding member11K holds the first member301, between a first state in which a gap is formed between the first bonding member11K and a part of the side surface of the first member301, which is continuous with the crimping surface with the second member302, and a second state in which the gap is filled to control the position of the first member301.

The second bonding member may be any member as long as the second bonding member holds the second member302and can bring the second member302into contact with the first member301held by the first bonding member11K when covering the first bonding member11K.

In the twelfth embodiment, when the second bonding member is attached, the operation portion151is pushed to move the first wall portion112A and the second wall portion113A in directions toward each other. After the bonding process, the pressing of the operation portion151is released to move the first wall portion112A and the second wall portion113A in directions away from each other.

In a state where the operation portion151is pushed in, a distance between the first wall portion112A and the second wall portion113A is greater than the width of the first member301(width d4illustrated inFIG.7). Setting is so made that the distance between the first wall portion112A and the second wall portion113A is substantially equal to the width d4in a state where a load other than gravity is not applied to the operation portion151.

As with the first embodiment, in the twelfth embodiment, when the constituent members of the bushing31are attached to and detached from the bonding members, a gap is provided between the first wall portion112A and the first member301as well as between the second wall portion113A and the first member301to enhance the workability. When the first member301and the second member302are crimped onto the body portion2, the first member301is sandwiched by the first wall portion112A and the second wall portion113A to fix the position, which enables crimping while misalignment of the crimping surfaces of the first member301and the second member302with respect to the body portion2is prevented. According to the twelfth embodiment, it is possible to prevent the reduction in workability while the bushing31is reliably crimped onto the body portion2.

Thirteenth Embodiment

Next, the thirteenth embodiment of the present invention will be described with reference toFIG.26.FIG.26is a plan view for explanation of a configuration of a bonding jig for bonding a bushing to a body portion in the thirteenth embodiment. In the thirteenth embodiment, a configuration of a first bonding member will be described.

A first bonding member11L according to the thirteenth embodiment includes a bottom surface portion111D on which the first member301is placed, and a first wall portion112E and a second wall portion113E which are erected, with respect to the bottom surface portion111D, on the side of both ends of the bottom surface portion111D.

The first wall portion112E and the second wall portion113E are formed with switching surfaces112band113b,respectively. Each of the switching surfaces112band113bconstitutes a wall surface facing the bottom surface portion111D and forms an acute angle with the wall surface facing the first member301. Therefore, the first wall portion112E and the second wall portion113E are inclined in such a manner that the switching surfaces and the bottom surface portion111D make a surface contact with each other under their own weights in a natural state where a load other than gravity is not applied. As a result, in the natural state, the wall surfaces of the first wall portion112E and the second wall portion113E facing the first member301are inclined, and a gap is formed between the first member301and each of the first wall portion112E and the second wall portion113E. The first wall portion112E and the second wall portion113E, in particular, the switching surfaces112band113b,are included in a switching mechanism that switches, in a space where the first bonding member11L holds the first member301, between a first state in which a gap is formed between the first bonding member11L and a part of the side surface of the first member301, which is continuous with the crimping surface with the second member302, and a second state in which the gap is filled to control the position of the first member301.

The second bonding member may be any member as long as the second bonding member holds the second member302and comes into contact with the first wall portion112E and the second wall portion113E to move the first wall portion112E and the second wall portion113E toward the bottom surface portion111D when covering the first bonding member11L. For example, the application is made possible by adjusting the positions of the first wall portion122and the second wall portion123of the second bonding member12.

At this time, attaching the second bonding member rotates the first wall portion112E and the second wall portion113E, so that the switching surfaces112band113bare spaced from the bottom surface portion111D and the first wall portion112E and the second wall portion113E approach each other. When the second bonding member is detached, in the first wall portion112E and the second wall portion113E, the first wall portion112E and the second wall portion113E rotate, the switching surfaces112band113bcome into contact with the bottom surface portion111D, and the first wall portion112E and the second wall portion113E move away from each other.

Here, in a state where no load from the second bonding member is placed on the first bonding member11L, the maximum distance between the first wall portion112E and the second wall portion113E is greater than the width of the first member301(width d4illustrated inFIG.7). Setting is so made that the distance between the first wall portion112E and the second wall portion113E is substantially equal to the width d4when the second bonding member is attached to the first bonding member11L.

As with the first embodiment, in the thirteenth embodiment, when the constituent members of the bushing31are attached to and detached from the bonding members, a gap is provided between the first wall portion112E and the first member301as well as between the second wall portion113E and the first member301to enhance the workability. When the first member301and the second member302are crimped onto the body portion2, the first member301is sandwiched by the first wall portion112E and the second wall portion113E to fix the position, which enables crimping while misalignment of the crimping surfaces of the first member301and the second member302with respect to the body portion2is prevented. According to the thirteenth embodiment, it is possible to prevent the reduction in workability while the bushing31is reliably crimped onto the body portion2.

In the fourteenth embodiment, a configuration of a first bonding member will be described.

A first bonding member11M according to the fourteenth embodiment includes a bottom surface portion111E on which the first member301is placed, and the first wall portion112A and the second wall portion113A which are erected, with respect to the bottom surface portion111E, on the side of both ends of the bottom surface portion111E.

The bottom surface portion111E has a tubular shape in which one end is bifurcated, an air flow path is formed inside, and the first member301is placed. The bottom surface portion111E includes a first opening portion111a,a second opening portion111bthat communicates with the first opening portion111a,is provided at one bifurcated end, and faces the first wall portion112A, and a third opening portion111cthat is provided at the other bifurcated end, and faces the second wall portion113A. Air introduced into the first opening portion111aor sucked from the first opening portion111aadjusts air sucked or blown out from the second opening portion111band the third opening portion111c.When air is blown out from the second opening portion111band the third opening portion111c,the first wall portion112A and the second wall portion113A move in directions away from each other. When air is sucked from the second opening portion111band the third opening portion111c,the first wall portion112A and the second wall portion113A move in directions toward each other.

The bottom surface portion111E is included in a switching mechanism that switches, in a space where the first bonding member11M holds the first member301, between a first state in which a gap is formed between the first bonding member11M and a part of the side surface of the first member301, which is continuous with the crimping surface with the second member302, and a second state in which the gap is filled to control the position of the first member301.

The second bonding member may be any member as long as the second bonding member holds the second member302and can bring the second member302into contact with the first member301held by the first bonding member11M when covering the first bonding member11M.

In the fourteenth embodiment, when the second bonding member is attached, air is sucked from the first opening portion111ato bring the first wall portion112A and the second wall portion113A close to each other. After the bonding process, air is introduced into the first opening portion111ato blow air to the first wall portion112A and the second wall portion113A to move the first wall portion112A and the second wall portion113A in directions away from each other.

When the first member301is attached or detached, a distance between the first wall portion112A and the second wall portion113A is greater than the width of the first member301(width d4illustrated inFIG.7). Setting is so made that the distance between the first wall portion112A and the second wall portion113A is substantially equal to the width d4when the first member301and the second member302are bonded together.

As with the first embodiment, in the fourteenth embodiment, when the constituent members of the bushing31are attached to and detached from the bonding members, a gap is provided between the first wall portion112A and the first member301as well as between the second wall portion113A and the first member301to enhance the workability. When the first member301and the second member302are crimped onto the body portion2, the first member301is sandwiched by the first wall portion112A and the second wall portion113A to fix the position, which enables crimping while misalignment of the crimping surfaces of the first member301and the second member302with respect to the body portion2is prevented. According to the fourteenth embodiment, it is possible to prevent the reduction in workability while the bushing31is reliably crimped onto the body portion2.

Fifteenth Embodiment

Next, the fifteenth embodiment of the present invention will be described with reference toFIG.28.FIG.28is a perspective view for explanation of a configuration of a bushing member in the fifteenth embodiment. In the fifteenth embodiment, a configuration of a bushing member will be described.

A bushing member3A includes a bushing31and a bracket32.

As with the first embodiment, the bushing31is made using an elastic material such as rubber or an elastic resin, and functions as a damping member that reduces vibration or the like of the stabilizer1transmitted from a road surface or the like. The bushing31includes two members (a first member301and a second member302). In the fifteenth embodiment, the first member301and the second member302constituting the bushing31are divided in a direction parallel to the longitudinal direction of the body portion2and orthogonal to the first embodiment.

Even in the divided bushing31in the aspect according to the fifteenth embodiment, the members can be bonded to each other using the same bonding jig as in the first to fourteenth embodiments, and thus the same effect as in the first embodiment can be obtained.

Although the embodiments for carrying out the present invention have been described so far, the present invention should not be limited only to the above-described embodiments. For example, the present invention is applicable to a product manufactured by a thermal compression process.

In the embodiments described above, the example of using an IH coil as a heating member for a heat treatment has been described, but the heating member is not limited thereto, and known heating (e.g., heating by energization or heating by hot air) can be used, and can be appropriately selected depending on the heating efficiency or the like.

In the embodiments described above, the example in which a bushing coupled to the body of a vehicle is bonded to a stabilizer has been described; however, the bonded member is not limited to the stabilizer. The present invention can be applied to any bonded member as long as the member is a bonded member that is interposed between the connection targets and to which a damping member for reducing vibration or the like between the connection targets is bonded, and a bonded member to which a damping member is bonded regardless of whether the bonded member is heated or unheated. Examples of the bonded member include a winding spring, a leaf spring, a torsion bar, and a disk spring in addition to the stabilizer. For example, in the winding spring, an insulator is used as the damping member.

As described above, the present invention can include various embodiments and the like not described herein, and various design changes and the like can be made without departing from the technical idea specified by the claims.

INDUSTRIAL APPLICABILITY

As described above, the bonding jig and the bonding method according to the present invention are suitable for preventing the reduction in workability while a damping member is reliably crimped onto a bonded member.
