Hereinafter, reference will be made to a bolt according to an embodiment of the present invention, while referring to the accompanying drawings.

Figs. 1A through 1E illustrate an external screw member according to one embodiment of the present invention, wherein Fig. 1A is a front view of the entire external screw member; Fig. 1B is a half cross sectional view along line B-B; Fig. 1C is an enlarged view of a convex portion in Fig. 1A; Fig. 1D is an enlarged cross sectional view of the convex portion in Fig. 1C; and Fig. 1E is a partial perspective view of a convex portion end face at the screw driving side of the convex portion.
如图1的(A)所示，外螺纹部件1具备头部2和轴部3，作为轴部3，从头部2侧朝向轴部3的前端侧，依次具备平行螺钉部31和锥形螺钉部32。
As illustrated in Fig. 1A, an external screw member 1 is provided with a head 2 and a shank 3, and the shank 3 is provided with a parallel threaded portion 31 and a tapered threaded portion 32 in order from the side of the head 2 to the side of a tip end of the shank 3.
关于头部2的形状，尽管在图中例示出六角形状，但并未特别地局限于此，可应用各种形状的头部形状。
For the shape of the head 2, a hexagonal shape is illustrated as an example in Fig. 1A, but the shape of the head 2 is not limited in particular, and a variety of shapes of the head 2 can be applied.
另外，尽管在图示例中例示出有效直径螺栓，但也可以应用于标称直径螺栓。
Here, note that in the illustrated example, a bolt with a pitch diameter body is shown as an example, but the invention can also be applied to a bolt with a nominal diameter body.
平行螺钉部31和锥形螺钉部32中，螺纹5以同一螺距连续设置，锥形螺钉部32中，螺纹5以牙峰高度逐渐减小的形式设置。
A screw thread 5 is continuously formed in the parallel threaded portion 31 and the tapered threaded portion 32 at the same or constant pitch, and the screw thread 5 is formed in such a shape that in the tapered threaded portion 32, the height of the thread 5 (thread height) gradually decreases.
当平行螺钉部31的区域中的螺纹5设为平行螺纹51时，平行螺纹51是具有固定的外径和底径的螺纹，当将锥形螺钉部32的区域中的螺纹5设为锥形螺纹52时，锥形螺纹52采用与平行螺钉部31的平行螺纹51相同螺距，从平行螺钉部31朝向前端侧，以外径及牙峰高度逐渐减小的形式设置。
When the screw thread 5 in the range of the parallel threaded portion 31 is assumed as a parallel screw thread 51, the parallel screw thread 51 is a screw thread which has a constant outside diameter and a constant root diameter, whereas when the screw thread 5 in the range of the tapered threaded portion 32 is assumed as a tapered screw thread 52, the tapered screw thread 52 is formed in such a shape that it has the same pitch as the parallel screw thread 51 of the parallel threaded portion 31, and that the outside diameter and the height of the thread 52 gradually decrease from the parallel threaded portion 31 toward the tip end thereof.
在从锥形螺钉部32至平行螺钉部31所涉及的螺纹5的一部分中设置有凸部4，所述凸部4比起螺纹5的顶部5a(以下为螺纹顶部5a)更向径向外方突出。
In a part of the screw thread 5 extending from the tapered threaded portion 32 to the parallel threaded portion 31, there are formed convex portions 4 protruding in a radially outer direction from the crest 5a of the screw thread 5 (hereinafter, referred to as a screw thread crest 5a).
在该实施方式中，凸部4是在螺纹的每1圈均等地配置有3个，因此在平行螺钉部31的平行螺纹51中一圈设有3个，且在锥形螺钉部32的锥形螺纹52中2圈设有6个，作为整体是设有9个。
In this embodiment, three convex portions are provided at an equal pitch for each turn of the screw thread (i.e., three convex portions per turn of the thread), and more specifically, three pieces of convex portions are arranged for one turn of the parallel screw thread 51 in the parallel threaded portion 31, and six pieces of convex portions are arranged for two turns of the tapered screw thread 52 in the tapered threaded portion 32, and hence, nine pieces of convex portions in total are arranged as a whole.
在每一圈所配置的3个凸部4在3圈在周向上的相位均为同一相位，因此在轴向上串联排列。
Three convex portions arranged for each turn of the screw thread are identical in circumferential phase with those of the three turns, and are arranged axially in series with those of the three turns.
图1的(A)中仅表示各螺纹一圈3个中的一个凸部4，其余2个凸部位于纸面背侧。
In Fig. 1A, only one convex portion 4 is illustrated among three pieces of convex portions for one turn of the screw thread, and the remaining two convex portions are located at the back side of the drawing sheet.
凸部4比起设有凸部4的部分中的螺纹5的外径更向径向外方突出。
The convex portions 4 each project in the radially outer direction from the outside diameter of the screw thread 5 in the portions in which the convex portions 4 are formed.
锥形螺纹52如图1的(C)所示，朝向平行螺纹51呈螺旋状逐渐扩径，设置在锥形螺纹52的凸部4中，位于螺钉最前侧的凸部4的直径是最小直径，且随着锥形螺纹52扩径，直径逐渐增大，设置在平行螺纹51的3个凸部4为最大径且为固定直径。
In the convex portions 4 formed in the tapered screw thread 52, the most tip side convex portion located at the most tip side of the screw thread 52 is the smallest in diameter, and as the tapered screw thread 52 increases in diameter from its tip end toward the parallel screw thread 51, the diameters of the convex portions 4 become gradually larger, so that the three convex portions 4 formed in the parallel screw thread 51 are the largest in diameter and have a constant diameter.
该凸部4相对于螺纹5的牙峰高度方向的突出量是固定的，凸部4的外径成为跟随着锥形螺纹52的外径朝向螺钉前端而缩径的形式。
An amount of protrusion of each convex portion 4 in the height direction with respect to the screw thread 5 is constant, and the outside diameter of each convex portion 4 is formed to decrease toward the tip of the screw, following the outside diameter of the tapered screw thread 52.
关于螺纹5的一圈的凸部4的数量，优选为，在圆周上在1～10个的范围内设置。
Here, it is preferable that the number of convex portions 4 be in the range of 1 to 10 pieces on the circumference for one turn of the screw thread 5.
若是该程度，则能够扩大凸部4的间隔，易于滚轧加工，而且与通常的螺纹成形相比工具寿命也是相同的。
In such a range, the interval of adjacent convex portions 4 can be taken sufficiently wide, and hence, form rolling or component rolling of the convex portions 4 is easy, and a tool life in this case is also not changed in comparison with the case of general screw thread shaping.
另外，鉴于进一步的滚轧加工的难易度、工具寿命的观点、螺钉成形时的切屑的产生量、排出功能，1～8个是较佳的。
However, when considering the ease of further form rolling, the point of view of the tool life, the amount of chips generated and the function of discharging chips at the time of screw thread shaping, 1 to 8 pieces of convex portions are more preferable.
接下来，参照图1的(C)至(E)对凸部4进行详细说明。
Next, a convex portion 4 will be described in detail, while referring to Figs. 1C through 1E.
尽管图1的(C)至(E)为形成在平行螺纹51的凸部4，但形成在锥形螺纹52的凸部4也基本上是同一结构，因此将平行螺纹51和锥形螺纹52统称为螺纹5，并且对螺纹5与凸部4的关系进行说明。
Although Figs. 1C through 1E illustrate one convex portion 4 formed in the parallel screw thread 51, the convex portions 4 formed in the tapered screw thread 52 are each also basically of the same structure, so in the following explanation, the parallel screw thread 51 and the tapered screw thread 52 will be comprehensively handled as a screw thread 5, and relations of the parallel screw thread 51 and the tapered screw thread 52 with the convex portions 4 will be explained as a relation between the screw thread 5 and the convex portions 4 (hereinafter, sometimes simply referred to as the convex portion 4).
凸部4包括：沿着螺纹5的螺纹顶部5a以预定长度延伸的凸部顶部4a、从该凸部顶部4a朝头部侧的牙底延伸的压力侧凸部牙侧4b、以及从凸部顶部4a朝螺钉前侧的牙底延伸的非承载侧凸部牙侧4c，并且在穿过轴部3的中心轴线N的表面上切断的截面形状为，具备预定宽度的凸部顶部4a的三角形状的山形。
The convex portion 4 is provided with a convex crest 4a extending a predetermined length along the screw thread crest 5a of the screw thread 5, a pressure side convex flank 4b extending from this convex crest 4a toward a thread bottom at the side of the head 2, and a clearance side convex flank 4c extending from the convex crest 4a toward a thread bottom at the side of a screw tip, wherein a cross sectional shape cut on a surface passing through a central axis N of the shank 3 is a triangular pyramid shape provided with the convex crest 4a of a predetermined width.
凸部顶部4a的从螺纹顶部5a起的突出高度h为沿周长方向处于相同高度(从轴部的中心轴线起的直径是相同的)，旋入侧的凸部端面4d朝向螺纹顶部5a以根部侧朝旋入方向前方突出的方向的方式倾斜。
A projection height h of the convex crest 4a from the screw thread crest 5a is the same or constant along the circumferential direction (i.e., the diameter of the convex crest 4a from the central axis of the shank 3 is the same), and a convex portion end face 4d at the screw driving side inclines in a direction in which a root side portion thereof protrudes forward in the screw driving direction toward the screw thread crest 5a.
即，旋入侧的凸部端面4d成为如下的倾斜面，即，螺纹顶部侧的端缘d1的位置位于比起凸部顶部侧的端缘d2更靠旋入方向前方(周向的相位朝旋入方向前方仅前进角度γ的位置)，并且从螺纹顶部5a侧的端缘d1朝向凸部顶部4a侧的端缘d2，在螺纹5的旋入方向的相反方向W2上逐渐立起直至凸部4的顶部4a的倾斜面。
That is, the convex portion end face 4d at the screw driving side is a slope or inclined surface in which the position of an end edge d1 at the side of the screw thread crest is located ahead of an end edge d2 at the side of the convex crest in the screw driving direction (i.e., in a position in which a phase in the circumferential direction is advanced forward by an angle γ in the screw driving direction), wherein the slope or inclined surface gradually rises up from the end edge d1 at the side of the screw thread crest 5a toward the end edge d2 at the side of the convex crest 4a in a direction W2 opposite to the screw driving direction of the screw thread 5, and leads to the crest 4a of the convex portion 4.
凸部顶部4a的轴向(中心轴线N的平行方向)的宽度(以下为牙峰宽度)大于螺纹顶部5a的牙峰宽度，并且相对于螺纹顶部5a而向高度方向突出并且还向牙峰宽度方向突出。
A width in an axial direction (i.e., in a direction parallel to the central axis N) of the convex crest 4a (hereinafter, referred to as a crest width) is larger than the crest width of the screw thread crest 5a, and the convex crest 4a protrudes in a height direction and in a crest width direction as well with respect to the screw thread crest 5a.
即，压力侧凸部牙侧4b及非承载侧凸部牙侧4c在凸部顶部4a侧，比起螺纹5的压力侧牙侧5b及非承载侧牙侧5c更向牙峰宽度方向延伸出一段。
That is, the pressure side convex flank 4b and the clearance side convex flank 4c protrude more in the crest width direction at the side of the convex crest 4a than the pressure side flank 5b and the clearance side flank 5c of the screw thread 5.
另一方面，压力侧凸部牙侧4b及非承载侧凸部牙侧4c的谷部侧的下端缘的牙峰宽度与相同高度的螺纹5的压力侧牙侧5b及非承载侧牙侧5c的下端缘的牙峰宽度几乎一致。
On the other hand, a thread root width between the root side lower end edges of the pressure side convex flank 4b and the clearance side convex flank 4c is substantially identical or equal to a thread root width between the root side lower end edges of the pressure side flank 5b and the clearance side flank 5c of the screw thread 5 with the same height as the convex portion 4.
因此，压力侧凸部牙侧4b及非承载侧凸部牙侧4c如图1的(D)所示，从凸部顶部4a朝向牙底直线倾斜，该压力侧凸部牙侧4b的牙侧角θx1小于螺纹5的压力侧牙侧5b的牙侧角θa1，此外，非承载侧凸部牙侧4c的牙侧角θx2也小于螺纹5的非承载侧牙侧5c的牙侧角θa2。
Accordingly, the pressure side convex flank 4b and the clearance side convex flank 4c incline linearly from the convex crest 4a toward the thread bottom, as illustrated in Fig. 1D, wherein a flank angle θx1 of the pressure side convex flank 4b is smaller than a flank angle θa1 of the pressure side flank 5b of the screw thread 5, and a flank angle θx2 of the clearance side convex flank 4c is also smaller than a flank angle θa2 of the clearance side flank 5c of the screw thread 5.
尽管在图示例中，压力侧凸部牙侧4b的牙侧角θx1与非承载侧凸部牙侧4c的牙侧角θx2相同(θx1＝θx2)，螺纹5的压力侧牙侧5b的牙侧角θa1与非承载侧牙侧5c的牙侧角θa2相同(θa1＝θa2)，呈左右对称形状，但也可以非对称。
In the illustrated example, the flank angle θx1 of the pressure side convex flank 4b and the flank angle θx2 of the clearance side convex flank 4c are the same (θx1 = θx2), and the flank angle θa1 of the pressure side flank 5b and the flank angle θa2 of the clearance side flank 5c of the screw thread 5 are the same (θa1 = θa2), and hence, the convex portion 4 and the screw thread 5 each have a left-right symmetrical shape, but may be unsymmetrical.
即，也可以是压力侧凸部牙侧4b的牙侧角θx1与非承载侧凸部牙侧4c的牙侧角θx2不同(θx1≠θx2)，螺纹5的压力侧牙侧5b的牙侧角θa1与非承载侧牙侧5c的牙侧角θa2也不同(θa1≠θa2)。
That is, the flank angle θx1 of the pressure side convex flank 4b and the flank angle θx2 of the clearance side convex flank 4c may not be the same (θx1 ≠ θx2), and the flank angle θa1 of the pressure side flank 5b and the flank angle θa2 of the clearance side flank 5c of the screw thread 5 may not be the same (θa1 ≠ θa2), either.
另外，压力侧凸部牙侧4b及非承载侧凸部牙侧4c的下端缘(谷侧的端部)也可以止于螺纹5的压力侧牙侧5b及非承载侧牙侧5c的中途部。
Here, note that the lower end edges (root side end portions) of the pressure side convex flank 4b and the clearance side convex flank 4c may be middle portions of the pressure side flank 5b and the clearance side flank 5c of the screw thread 5.
旋入侧的凸部端面4d包括：从凸部顶部4a至螺纹顶部侧的端缘d1的呈梯形状的顶部区域4d1、和从顶部区域4d1分支的、沿压力侧凸部牙侧4b及非承载侧凸部牙侧4c的旋入方向的端缘呈倒V字状延伸的压力侧牙侧端部区域4d2及非承载侧牙侧端部区域4d3。
The convex portion end face 4d at the screw driving side is provided with a crest region 4d1 of a trapezoidal shape extending from the convex crest 4a to its end edge d1 at the side of the screw thread crest, and a pressure side flank end region 4d2 and a clearance side flank end region 4d3 branching from the crest region 4d1 and extending in an inverted V shape along the end edges in the screw driving direction of the pressure side convex flank 4b and the clearance side convex flank 4c.
但是，可以任意选择分度杆的数量，只要有多于一个的分度杆。
However, the number of indexing rods can be arbitrarily chosen, as long as there is more than one indexing rod.
此外，重要的是，分度杆以轴向力均匀分布的方式布置，以防止分度杆的屈曲(buckling)和卡住(jamming)。
Moreover, it is important that the indexing rods are arranged in such a manner that axial forces are evenly distributed in order to prevent buckling and jamming of the indexing rods.
现在将主要集中于图4来描述分度杆。
The indexing rod will be now described mainly by focusing on Fig. 4.
应当注意，图3的实施例应用了相同的分度装置，但是该分度装置的几个组件仅在图4中示出。
It is to be noted that the same indexing means is applied with the embodiment of Fig. 3, but several components of the indexing means are shown in Fig. 4 only.
另一方面，图3示出了分度所需的一些其他元件，例如在实施例中用作液压室的环形间隙53。
On the other side, Fig. 3 shows some other elements required for the indexing such as the annular gap 53, which is used as a hydraulic chamber in the embodiment.
在每个分度杆9的外端(即在底座1的外侧的一端)设置有固定的分度头91。
Each indexing rod 9 is provided with a fixed indexing head 91 on its outer end, that is, an end on the outer side of the pedestal 1.
此外，分度螺母95与分度杆9和分度头91同轴地设置，使得其布置在分度杆9的径向外部，但设置在分度头91的径向内部。
Moreover, an indexing nut 95 is arranged coaxially with the indexing rod 9 and the indexing head 91 such that it is arranged radially outside of the indexing rod 9, but radially inside of the indexing head 91.
此外，分度螺母95通过螺纹98与分度杆9螺纹接合。
Moreover, the indexing nut 95 is in thread engagement with the indexing rod 9 by means of a thread 98.
分度螺母95在其指向底座1的端部上具有止动环97和刻度装置，该止动环具有锥形截面。
On its end directed to the pedestal 1, the indexing nut 95 has a stopper collar 97 having a tapered section and scale means 94.
因此，可以说，当分度头通过分度杆9移动到底座的外侧(即分别朝向图3中的左侧和图4中的右侧)时，分度螺母95可以与分度头91一起移动。
Thus, it can be said that the indexing nut 95 is movable together with the indexing head 91 when the indexing head is moved by means of the indexing rod 9 to an outer side of the pedestal, that is, towards the left side in Fig. 3 and to the right side in Fig. 4, respectively.
此外，通过借助工具接合设置在止动环(stopper collar)97中的凹部(recess)97a(见图1)并旋转止动环97，可以根据需要适当地设置分度螺母95和分度头91之间的距离。
Moreover, by engaging recesses 97a (see Fig. 1 ) provided in the stopper collar 97 by means of a tool and rotating the stopper collar 97, a distance between the indexing nut 95 and the indexing head 91 can be appropriately set as is required.
特别地，为了精确设置距离，在分度螺母95上设置了刻度装置。
In particular, for accurately setting the distance, a scale means is provided on the indexing nut 95.
由于辊头7与分度杆9一起移动，因此可以根据需要适当地设置辊头7朝向底座1的内侧的距离。
Since the roll head is moving together with the indexing rod 9, thereby the roll head's 7 distance towards the inner side of the pedestal 1 can be appropriately set as desired.
参照图3，分度头91与止动环97之间的距离相当小。
With regard to Fig. 3, a distance between the indexing head 91 and the stopper collar 97 is rather small.
也就是说，分度头91几乎完全覆盖分度螺母95。
That is, the indexing head 91 is almost fully covering the indexing nut 95.
相反，图4描述了分度螺母95已经旋转到使得分度头91与止动环97之间的距离几乎延伸到可能的最大距离的程度的情况。
In contrast, Fig. 4 depicts a situation where the indexing nut 95 has been rotated to such an extent that the distance between the indexing head 91 and the stopper collar 97 is almost extended to the greatest possible distance.
因此，图4中的辊头7比图3中的辊头7移动得更靠近底座1。
Thus, the roll head 7 in Fig. 4 is moved much closer to the pedestal 1 than in Fig. 3.
因此，通过借助旋转分度螺母95来增加止动环97与分度头91之间的距离，减小辊头7与底座1之间的距离。
Thus, by increasing a distance between the stopper collar 97 and the indexing head 91 by means of rotating the indexing nut 95 a distance between the roll head 7 and the pedestal 1 is reduced.
另一方面，通过减小止动环97与分度头91之间的距离，可以增加辊7与底座1之间的距离。
On the other side, by decreasing the distance between the stopper collar 97 and the indexing head 91, the distance between the roll head 7 and the pedestal 1 can be increased.
根据本实施例，通过压缩弹簧92和压缩弹簧93来实现辊头7在远离底座1的方向上的这种移动。
According to the embodiment, such a movement of the roll head 7 in the direction away from the pedestal 1 is effected by means of compression springs 92 and 93.
这些弹簧92和93围绕分度杆9同轴地布置，并容纳在设置在底座1的内侧(分别指向机器中心和辊头7的一侧)的弹簧槽(spring pocket)17中。
These springs 92 and 93 are arranged coaxially about the indexing rod 9, and are accommodated in a spring pocket 17 provided on the inner side of the pedestal 1 (the side directed to the machine center and the roll head 7, respectively).
以上所述，仅提到了分度头91与分度螺母95之间的螺纹接合，因为这样的致动可能足以进行分度。
In the above, merely a thread engagement between the indexing head 91 and the indexing nut 95 was mentioned, since such an actuation could be sufficient for indexing.
然而，根据本实施例，分度头91的向外移动是液压作用的。
However, according to the embodiment, an outwards movement of the indexing head 91 is effected hydraulically.
也就是说，当向形成在辊头7的静态部分与套圈5之间的环形间隙53中供应诸如液压油的相应流体时，套圈5的凸缘51与辊头的凸缘73之间的距离增加(参见图3)。
That is, when supplying a corresponding fluid such as hydraulic oil into the annular gap 53 formed between the static part of the roll head 7 and the ferrule 5, a distance between the flange 51 of the ferrule 5 and the flange 73 of the roll head increases (see Fig. 3 ).
因此，整个辊头7朝向底座1的移动受到弹簧92和弹簧93的弹簧力的影响。
Thereby, movement of the whole roll head 7 towards the pedestal 1 is effected against the spring forces of the springs 92 and 93.
此外，由于辊头7的移动，与分度螺母95螺纹接合的分度头91在分度杆9的轴向上移动，即朝向底座的外侧移动。
Moreover, due to the movement of the roll head 7, the indexing head 91 being in thread engagement with the indexing nut 95 is moved into an axial direction of the indexing rod 9, i.e. towards an outer side of the pedestal.
因此，释放了止动环97与底座1之间的邻接，并且只要辊头7朝向底座移动，止动环97和底座之间的距离就会增加。
Thereby, an abutment between the stopper collar 97 and the pedestal 1 is released, and the distance between the stopper collar 97 and the pedestal is increased as long as the roll head 7 is moved towards the pedestal.
当辊头7到达所需位置时，或优选地朝向底座1到达略超出所需位置的位置时，旋转分度螺母95，使得止动环97再次接近底座1。
When the roll head 7 achieves a desired position, or preferably a position slightly beyond the desired position towards the pedestal 1, the indexing nut 95 is rotated such that the stopper collar 97 again approaches the pedestal 1.
执行该旋转直到分度螺母95上的刻度示出所需距离为止。
This rotation is performed until the scale on the indexing nut 95 shows the desired distance.
在这种状态下，如果辊头7的位置稍微超出所需位置(底座1的内侧与辊头之间的距离太短)，则止动环97与底座1之间仍有小间隙。
In this state, if the position of the roll head 7 is slightly beyond the desired position (the distance between the inner side of the pedestal 1 and the roll head is too short), there is still a small gap between the stopper collar 97 and the pedestal 1.
通过从环形间隙53释放液压来消除这个小间隙。
This small gap is removed by releasing the hydraulic pressure from the annular gap 53.
也就是说，通过释放液压，延伸的弹簧92和93的弹簧力使辊头7朝向机器中心移动。
That is, by releasing the hydraulic pressure, the spring forces of the extending springs 92 and 93 effect a movement of the roll head 7 towards the machine center.
因此，辊头7与底座1之间的距离再次增大，直到分度螺母95的止动环(环形件)97与底座1邻接。
Accordingly, the distance between the roll head 7 and the pedestal 1 is again increased until the stopper collar (ring part) 97 of the indexing nut 95 gets into abutment with the pedestal 1.
然后，设定辊头7的所需位置。
Then, the desired position of the roll head 7 is set.
借助设置在孔15中的滑动衬套96，有利于分度杆9向两个方向的轴向移动。
Axial movements of the indexing rod 9 into both directions are facilitated by means of a slide bushing 96 provided in the bore 15.
本发明已经通过当前优选实施例进行了描述，但是其范围仅由所附权利要求限定。
The invention has been described by means of a presently preferred embodiment, but its scope is merely defined by the attached claims.
具体地，可以应用液压驱动的分度杆和通过螺纹接合操作的杆的组合。
In particular, a combination of hydraulically actuated indexing rods and rods operating by thread engagement can be applied.
图5的(C)为锥形螺钉部穿过对应部件100的底孔101使设置在平行螺纹51的第1圈的凸部14最终成形在内螺纹102的螺纹形状的状态。
In addition, in a cross section of the convex portion 14, a thread or ridge shape of the parallel screw thread 51 is shown by an imaginary (phantom) line (an alternate long and two short dashes line) for the sake of comparison with the parallel screw thread 51.
