The positioning key 12 of all array distributions.
Further, in another embodiment, the positioning key 12 by bolts assemblies on 1 rear end face of jig main body.
As depicted in figs. 1 and 2（Bolt is not shown）, convenient for making positioning key 12.Certainly, positioning key 12 may be with jig main body 1
Integrated formed structure, but it is the increase in the difficulty that positioning key 12 is processed on jig main body 1.
Further optimization based on the present embodiment, in another embodiment, as shown in Figure 1, along 13 direction of channel
1 inner wall of jig main body offers guide groove 14, and feather key 21 is provided on top 2 outer wall, and the feather key 21 is slidably embedded
In guide groove 14.Top 2 can be avoided to be rotated in the channel 13 of jig main body 1.
Further, in another embodiment, the feather key 21 is embedded on top 2 outer wall.Convenient for making feather key
21.Certainly, feather key 21 and top 2 or integrated formed structure.
Further optimization based on the present embodiment, in another embodiment, as shown in figures 1 and 3, before described top 2
End face is plane, and top 2 front end face has circular conical surface.The circular conical surface can be further adapted with bent axle major part, favorably
In the clamping precision of further bent axle.Preferably, the angle of the circular conical surface and top 2 front end face is 60 °.In order to ensure circular conical surface
It is same axis with top 2 front end face, when processing circular conical surface, 1 centre bore is offered in the center of top 2 front end face
23, it can be ensured that the machining accuracy of circular conical surface.
Further optimization based on the present embodiment, in another embodiment, as shown in Figure 1, described top 2 be in type
Shape, the diameter of section of top 2 leading portion of the convex character shape are less than the diameter of section of top back segment, the front end of the jig main body 1 to
Central protuberance forms cricoid limiting stand 15, and the internal diameter of the limiting stand 15 is less than the diameter of section of top 2 back segment.Top 2 by
Top 2 back segment under the position-limiting action of limiting stand 15, can be limited in channel 13, keep away in convex character shape by front and rear two sections of compositions
Exempt from top 2 to fall from jig main body 1.
Further optimization based on the present embodiment, in another embodiment, as shown in Figure 1, top 2 rear end opens up
There is blind hole 22, described 5 one end of elastic element is set in blind hole, the other end is in contact with locating piece 5.Enable elastic element 5
It is enough to be reliably set between locating piece 3 and top 2.Preferably, elastic element 5 is helical spring.
