The setting device (5) comprises a first part (6) with a reference plane (16) and a second part (7) with a reference surface (17) which is arranged to lie against the tool part (3) during tooling of the work piece and which reference surface will be located near the working tool. The transfer device (4) shows two end surfaces (14, 15) of which the one is arranged to lie against the reference surface (13) on the flange (11) and the other against the reference surface (13) on the flange (11) and the other against the reference plane (16) in the first part (6) of the setting device (5). In the method to set the tool (1) or the tool part (3) the second part (7) of the setting device (5) is brought to a displacement in axial direction of the tool (1) by a radial turning in the tool (1) and relative to the first part (6) of the setting device (5) and permits or influences by that the tool part (3) or its working tool to a simultaneous adjustement in axial direction of the tool (1). The transfer device (4) transfers the reference of the reference surface (13) on the flange (11) to the reference surface (17) on the second part (7) of the setting device (5) via the reference plane (16) in the first part (6) of the setting device (5).

Description: A METHOD TO SET TOOLS AND A DEVICE FOR CARRYING OUT THE METHOD The present invention relates to a method to set tools, preferably rotary tools, intended to be arranged in working machines for tooling work pieces. The tool can comprise one or more tool parts having working tools, as cutting edges. Further, the tool can comprise at least a setting device and a transfer device. The transfer device shows here two end surfaces. There is a need to be able to simplify setting of a tool or tool part in order to reduce setting times and to attain a more rapid flow through. Further, there is a wish to increase the dimension of tools or tool parts and they also tend to do so at the same time as the precision in the tool may not be lost or be reduced. It is, of course, a wish to be able to increase the precision. Within for example the metal working industry and wood working industry, as in production of products of wood and in that respect, as an example, in production of prefabricated floors in the shape of laminated flooring panels where high precision in the laminate joints is necessary, there exist tools often with two or more rotatable tool parts with working tools, as cutting edges, where high precision in the tool and tool parts is necessary, as well as in adjustment of the tool when it is mounted and set in the working machine and during production meaning that the axially distance between the tool parts must be the intended, That is achieved by spacers of different kinds, as spacer rings or shims. However, the spacers are arranged between the tool parts and by that difficult of access to in adjustment and results in extensive dismounting of the tool involving considerable time consuming and unnecessary loss of precision in the tool. It also exists other spacers, as a pin, which is arranged between the tool parts but is located at a distance from the tool spindle, whereby precision in the axially distance between the tool parts is difficult to maintain. Wobbling in form of axial tosses is also a problem in the known methods and devices. The disadvantages in using the known devices can be considerably reduced and often be eliminated when a method in accordance with the present invention is used at the same time as a method in accordance with the invention results in additional advantages. One object with the method in accordance with the invention is thus to be able to realize a setting of a tool in a simpler and faster way and by that reduce setting times in adjustment during production but also in setting of a new tool in the working machine. Another object with the method in accordance with the invention is to achieve increased precision in the tool and also when the tool is adjusted at and during production and in any stops that may arise. An additional object with the method in accordance with the invention is to eliminate or reduce tendency of wobbling. The method in accordance with the invention is characterized in that the said transfer device is brought to run through a tool part and with a second end surface brought to lie against a surface on a first part of the said setting device. The setting device is brought to lie against the said tool part with a contact surface on a second part of the setting device. An adjustment of the tool or the said tool part comprises at this an axial movement or displacement of the said second part of the setting device in relation to the said first part of the setting device and permits or influences by that the said tool or tool part to a simultaneous adjustment. According to another characteristic for the method in accordance with the invention a first end surface of the said transfer device is brought to lie against a part, as a flange or similar, a bushing or hub comprised by the tool or against an adjacent or second tool part. An additional characteristic for the method in accordance with the invention the said first end surface of the said transfer device is brought to lie against a first reference plane or surface in the tool. The reference plane is at this in the shape of surface on the said flange or similar of the said bushing or hub or a surface on the adjacent or second tool part and transfers the reference plane through the said transfer device to the setting device and further on to the contact surface or contact plane for the contact of the said second part of the setting device with the tool or adjacent tool part. The invention relates also to a device for setting tools in utilization of a method in accordance with the invention, whereby a tool comprises one or more tool parts with working tools, as cutting edges, at least a setting device and a transfer device showing two end surfaces. The device is characterized in that a first tool part shows at least a number of through holes corresponding to the number of transfer devices and through which holes transfer devices are meant to run, that the transfer device shows a length exceeding the thickness of the said tool part, that the said first end surface is arranged to lie against a first reference plane which is arranged on an adjacent part in the tool and that the said second end surface is arranged to lie against a part or a first part of the said setting device. Another characteristic for the device in accordance with the invention is that the said setting device shows a second part, whereby the said first and second parts of the setting device are united to each other by means of a thread. According to an additional characteristic for the device in accordance with the invention an anchoring device holds the said transfer device fast against an adjacent or second tool part or against a flange or similar shown by a bushing or hub comprised by the tool. Still another characteristic for the device in accordance with the invention is that a fastening device holds the said setting device or its second part fast against the said transfer device, whereby the axial distance between said first part of the setting device and the said adjacent or second tool part or the said flange or similar shown by the said bushing or hub can be kept or be held unchanged also during adjustment of the axially distance between adjacent tool parts or the said first and second tool parts. According to an additional another characteristic for the device in accordance with the invention the said second part of the setting device can be arranged adjustable or axially displaceable in relation to the said first part of the setting device or a said reference plane and also during the arrangement of the tool in the working machine, whereby the said second part of the setting device shows a contact surface or a plane against which said first or adjacent tool part is arranged to lie. In one more another characteristic for the device in accordance with the invention the device comprises a holding device, for example in the shape of a spiral spring or cup springs, which is designed for securing that the first tool part maintains contact or contact with said second part of the setting device or its said contact surface or plane during the adjustment operation of the tool. In known devices it is often used, as said, spacer rings or so called shims when the tool is going to be set. It can be difficult to attain the precision wanted and besides, spacer rings or shims are liable to build far too much. It has also been proposed to adjust the axial distance between two tool parts or adjacent tool parts by arranging a pin between the tool parts and which pin is brought to expand the tool parts away from each other. As it at this is a matter of hub-mounted tools said single pin is arranged beside the centre of the tool parts, whereby a certain warping is difficult to avoid because of the prize effect resulting in that fact that wobbling easily arise in the tool. Setting of known tools of the kind in question are done in connection with the hub or in its nearness, whereby only a minor divergence in precision or a less error is enlarged many times, as the distance from the setting place to the real working tool is large. As the tendency is to increase the dimension of the tool parts the said distance will be even longer with even larger divergences in precision caused by only a slight error. The risk of wobbling might probably increase still more. A device according to the present invention is building considerably less than what is the case in using the current spacer rings or shims. By utilization of transfer devices as in the device according to the invention and which are equally divided in the tool, as three or four arranged in relative same distance or radius, tendency of warping resulting in wobbling is avoided. Further, one can produce high precision in connect ing surfaces or connecting planes between the transfer devices and contacted parts in the tool. By means of the transfer devices one transfers or moves the reference plane closer to or next to the real working tool besides that one transfers the reference plane to a more accessible place in the tool, the affecting reference plane will exists in a substantially greater diameter than what is customary, whereby a minor error or divergence, if any, will not be added up or enlarged materially. The risk of worse precision in enlarging the dimension of the tools does not either exist in a device according to the invention. Probably, the fact is rather that an even higher precision could be achieved. Further characteristics of and advantages with the method and the device in accordance with the invention will in the following description be apparent by embodiment examples, whereby a simultaneous reference will be made to the accompanying schematic drawings, of which Fig. 1 shows partially in cross section a part of a tool according to one embodiment, Fig. 2 shows partially in cross section a part of a tool according to a second embodiment, Fig. 3 shows partially in cross section a part of the tool shown in Fig. 2 but in another section, Fig. 4 shows from one side a view of a setting device according to one embodiment, Fig. 5 shows from another side and in cross section the setting device according to Fig. 4, Fig. 6 shows in cross section a part of a first body in a setting device, Fig. 7 shows in cross section a part of a second body in the setting device, Fig. 8 shows partially in cross section a part of a tool according to a third embodiment and Fig. 9 shows partially in cross section a part of a tool according to a fourth embodiment and where the tool is arranged in contact with a spindle or an engine shaft and thus without a sleeve or bushing. With the reference designation 1 in Figs. 1,2,3,8 and 9 is shown a tool comprising at least a first tool part 3, transfer devices 4 and a setting device 5. The tool 1, which is shown in Figs. 2,3,8 and 9, comprises also a second tool part 2. In the peripheral area and along the circumference of the tool parts 2,3 are arranged working tools, for example cutting edges of diamond for tooling a work piece, for example of wood or material based on wood fibre. The working tools are not shown in said figures. It is further evident from said figures except for the embodiment shown in Fig. 9 that the tool 1 comprises a hub 10 or a bushing in the shape of a mounting sleeve for the arrangement of the tool 1 on a spindle 9, engine shaft or similar which spindle or similar is evident from the embodiment shown in Fig. 9. The said mounting sleeve 10 shows a flange 11 or similar the inside of which shows an arranged surface 13 which can be said to form a setting base for the tool 1 or a first or an initial reference surface or plane for the tool. In the embodiment shown in Fig. 1 and where the tool 1 comprises only a first tool part 3, a first end surface 14 of the transfer device 4 is arranged to lie against the flange surface 13 or the said first reference plane 13. In the other embodiments shown in the said figures, the said first end surface 14 of the said transfer device 4 is arranged in contact with a reference surface 12 or plane which is arranged on the adjacent tool part 2 or the second tool part 2 which in turn is arranged resting against the flange surface 13 of the mounting sleeve's 10 flange 11 or its first reference plane 13 except for the embodiment shown in Fig. 9 where the tool 1 is lacking in mounting sleeve and is arranged in contact with the spindle 9 or engine shaft of the machine. The transfer device 4 shows a second end surface 15 which is arranged to lie against a surface 16 on the setting device 5 or a first part 6 comprised by the the setting device 5. The setting device device 5 shows also a second part 7 which in the tool 1 depening on certain conditions is arranged movable or turnable in relation to the said first part 6 of the setting device 5. Both said parts 6,7 in the setting device 5 are united with each other by means of a thread 30. According to an embodiment of the device in accordance with the invention the tool 1 shows at least two transfer devices 4 and according to another embodiment three transfer devices 4 and according to a preferred embodiment four transfer devices 4 when the tool 1 comprises one tool part 3 or two adjacent tool parts 2,3. In the following description of the said embodiment examples reference will be made to the last-mentioned embodiment with four transfer devices 4. The first tool part 3 shows at this at least four through holes 23 for transfer devices 4 to run through said tool part and which holes are arranged equally divided with one another. Corresponding number of through holes 26 with seat for attachment devices 27 are arranged in the said first part 6 of the setting device 5, see also Fig. 4, showing a setting device 5 from one of the sides, the open side. Further exist one or more engagement devices 25 in the first tool part 3 or according to the embodiment example four engagement devices 25 which can consist of a thread or a threaded hole for a locking device 28 in the shape of, for example, a screw, see Fig. 3. The first part 6 of the setting device 5 shows in this case a corresponding number of through holes 26 with seat for the locking devices 28, as is evident from Fig. 4. The second tool part 2 shows according to the embodiment example at least four through holes 22 with seat or countersink. if required, for attachment devices 29. If the tool 1 is lacking in a mounting sleeve 10 or similar the second tool part 2 does not need more engagement devices, holes or similar according to the embodiment example described. In the case the tool 1 comprises a mounting sleeve 10 or similar, engagement devices 20 for the engagement of one or more anchoring devices 21 exist in the second tool part 2 or according to the emodiment example four engagement devices 20 which can consist of a thread or a threaded hole. The said flange 11 or similar in the mounting sleeve 10 shows at this through holes 38 for the anchoring device 21 with seat for the anchoring device. Besides the said surface 16 as a reference plane, the setting device 5 also shows a second reference surface 17 or plane which is arranged on the said second part 7 in the setting device 5 and against which reference plane 17 the tool 1 or the first tool part 3 is going to lie. Thus, the transfer device 4 transfers the reference of the reference plane 12 in the second tool part 2 to the reference plane 17 in the second part 7 of the setting device 5 and which reference plane is located near the working tool and said transfer is done via the reference plane 16 or surface on the first part 6 of the setting device 5. In case the tool 1 comprises only one tool part 3 the transfer device 4 transfers the reference of the reference plane 13 in the said flange 11 shown by the mounting sleeve 10 to the reference plane 17 in the second part 7 of the setting device 5. In this case as well, said transfer is done via the reference plane 16 or surface on the first part 6 of the setting device 5. In order that the transfer of the references will become correct, both end surfaces 14,15 on the transfer device 4 and the different reference surfaces 12,13,16,17 or reference planes are worked out with exactitude and with fine tolerances. The setting device 5 which is evident from the embodiment shown in Figs. 4-7 consist at this of a first part 6 in the shape of an inner ring which is fixed in the tool 1 or to the first tool part 3 and a second part 7 in the shape of an outer ring which, during working operations, will be fixed relative to the first part 6 in the setting device 5. When the tool 1 is to be adjusted i. e., according to one embodiment example, the second part 7 in the setting device 5 is unfixed so that the second part 7 can be turned in relation to the first part 6 for adjustment of the tool 1 or change of the first tool part's 3 axial distance to the second tool part 2. In order to make the setting and the adjustment easier the top surface of the second part 7 can be provided with a graduation 34 and for the turning different holds of which one is shown by the reference designation 35 and is in the shape of a finger-grip or recess in the surface of the body. With thr reference designations 16 and 17 are shown the reference surfaces or reference planes in the setting device's 5 first part 6 and second part 7 respectively. The connection device between the both parts 6,7 is in the shape of a thread 30, as mentioned, whereby the first part 6 shows an external thread 31 and the said second part 7 an internal thread 32. In connection with the thread 31 on the first part 6, a groove 33 to the bottom of the thread and a guiding surface 39 are arranged and on the second part 7 a guiding surface 40 in order to hold both parts 6,7 in the, setting device 5 with no or only a slight play in order to prevent tosses. However, for the precision it is important that the thread 30,31,32 itself is shaped with fine tolerances and is well-polished. Both parts 6,7 must keep parallelism and remove tosses, whereby it is here meant tolerances of some hundredth part millimetre and in some surfaces tolerances of some thousandth millimetre. Thus, it exists only a slight play in axial direction while a certain play is permitted radially for the possibility to be able to turn the said second part 7 relatively to the first part 6. The thread 30 can consst of a buttress thread with straight angle and small pitch. The large diameter permits improved precision in adjustment of the tool 1. The both parts 6,7 of the setting device 5 show each of them a contact surface 16 and 17 respectively or a reference plane, whereby said reference planes 16,17 are located on the same side in the setting device 5 and are turned towards the tool 1, the second tool part 2 and/or the first tool part 3 and/or in applicable cases towards the said flange 11 or flange surface or their's reference plane 12 and 13 respectively, whereby the said reference planes 16,17 in the setting device 5 are parallel or principally parallel with the said reference planes 12, 13 in the second tool part 2 and the flange 11 respectively. The anchoring device 21 anchors the said second tool part 2 to the tool 1 and is running through the said flange 11. By means of the attachment device 29, which is running through the said second tool part 2 and is in engagement with the transfer device 4, the said first part 6 in the setting device 5 is held in a mutual fixed position by the fact that the attachment device 27 is running through the said first part 6 and. is in engagement with the transfer device 4. The transfer device 4 forms by means of the settlement of its length beforehand and its with precision shaped end surfaces 14,15 a distance means between the second tool part 2 and the setting device 5 or its first part 6 and their's respective reference plane 12,16 extends parallel or mainly parallel with each other and by that also the reference planes 17 in the said second part. 7 of the setting device 5. The first tool part 3 is arranged between the second tool part 2 and the setting device 5 and lie against the reference plane plane 17 or surface shown by the second part 7 of the setting device 5, whereby the intended axially distance exists between the both tool parts 2,3 or their's working tools. In order to lock the axial position set for the first tool part 3 and its contact with the second part's 7 reference plane 17 of the setting device 5, the tool 1 shows locking devices 28 running through the first part 6 of the setting device 5 and are in engagement with the first tool part 3. In adjusting of the tool 1 and change of the axial distance between the tool parts 2, 3 said locking devices 28 must be loosen so that a lesser contact pressure is received between the first tool part 3 and the contact surface 17 in the second part 7 of the setting device 5. The both parts 6, 7 in the setting device 5 are held in a locked position with each other by the second part's 7 contact against the secon d tool part 3 or vice versa. One could say that a locking by friction exists between the two parts 3 and 7 respectively. The said attachment devices 27 which are in engagement with the transfer devices 4 are not unfasten in adjustment of the tool 1. The tool 1 comprises a holding device 18 holding the first tool part 3 against the said contact surface 17 during the adjustment of the tool 1 so that the first tool part 3 will keep resting or contact against the contact surface 17 shown by the second part 7 of the setting device 5. The holder devices 18 can be in shape of a helical spring according to the embodiment axample shown or be in shape of plate springs, whereby the springs 18 are arranged between the second tool part 2 and the first tool part 3 around the transfer device 4. Sealing devices 36 can be arranged in order to prevent enchroachment of dirt, chips or other contaminations between the both tool parts 2,3. The said anchoring devices 21, attachment devices 27,29 and locking devices 28 can be in shape of screws, whereby theirs engagement in adjacent tool parts 2,4 and 3 respectively is done by means of thread engagement. That is the reason why the transfer device 4 according to the embodiment examples shows a thread 24. With further reference to the embodiment shown according to Fig. 8, the said second part 7 of the setting device 5 is replaced with spacers 8 in the shape of spacer rings or so called shims, whereby that spacer which is turned towards the first tool part 3 can be dimensioned with somewhat more strength in order to ensure the precision in the tool 1 but shows likewise as previously a contact surface 17 or reference plane or surface. The transfer device 4 works in the tool 1 also as a driver or mechanical driver and as a torsional lock and consist of, according to the embodiment examples, a body in form of a sleeve with internal thread 24. Further, the length of the transfer device 4 is exactly the intended and shows fine tolerance, whereby the said end surfaces 14,15 are shaped especially well and thorough i. a. a surface grinding. The transfer devices 4 can be arranged with a marking 19 which is used when the transfer devices are produced to facilitate the obtaining of the required precision in the transfer device 4 or its first end surface 14. To obtain intended precision, the said reference planes 12,13 and the contact surfaces 16,17 of the setting device 5 are also grinded. The embodiment according to Fig. 9 refer as well to a transfer reference planes, namely the reference plane 12 to the contact surface 17 via the contact surface 16. An adjustment of tools 1 is also happen here. In this case, the first tool part 3 in the tool 1 is moved in adjustment as it is difficult to move a spindle in a working machine. The tool 1 or the tool parts 2,3 can be adjusted as said before and also a less adjustment axially of the tool 1 or the tool parts 2,3. Without exceeding the scope of the concept of the invention, modifications of the method and the device should be possible. The invention is thus not restricted to what has been evident from the embodiment examples but soley by the following claims.
