Position.
Compared with prior art, the beneficial effects of the utility model are：
A kind of internal tooth drilling part detent mechanism that the utility model is provided, mainly using alignment pin, and by alignment pin
Placed along the radial direction of internal tooth, while controlling the built-in length of alignment pin with elastic construction, it is ensured that space width is in tolerance model
It when enclosing interior any value, can be accurately positioned, and ensure that the relative position and the uniformity of hole site of hole and internal tooth.This reality
High with the detent mechanism positioning precision in new, convenient mounting and clamping is widely used to the folder that internal tooth class part drills on the face of cylinder
In tool.
Brief description of the drawings
Fig. 1 is the structural representation of detent mechanism；
Wherein, 1, fixture 2, internal tooth part 3, alignment pin 4, compression spring 5, holding screw 6, pressing plate 7, backboard
101st, mounting hole.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is further described.
On a kind of internal tooth drilling part detent mechanism that the utility model is provided, including fixture 1, the fixture 1
It is set with internal tooth part 2.Wherein, mounting hole 101, axis and the internal tooth zero of the mounting hole 101 are offered on the fixture 1
The axis of part 2 is mutually perpendicular to.
The mounting hole 101 is three-stage shoulder hole, and the three-stage shoulder hole is respectively the first shoulder hole, the second ladder
Hole and the 3rd shoulder hole, the aperture of first, second, and third shoulder hole increase successively, wherein, the 3rd shoulder hole is
First screwed hole.
Meanwhile, adapting device in alignment pin 3, the 3rd shoulder hole is provided with first shoulder hole holding screw
5, compression spring 4 is installed in the second shoulder hole between first shoulder hole and the 3rd shoulder hole.
The top of the fixture 1 offers screwed hole in the axial direction, leads between the internal tooth part 2 and fixture 1
Cross the first trip bolt coordinated with screwed hole to be connected, to fixed internal tooth part (2)；Meanwhile, the top of the internal tooth part 2
Outside is additionally provided with the pressing plate 6 for secondary compression, is connected between the pressing plate 6 and internal tooth part 2 by the second trip bolt,
Meanwhile, first trip bolt and the second trip bolt are coaxially disposed.
The fixture 1 is additionally provided with backboard 7 close to one end of holding screw 5, and the backboard 7 is arranged on internal tooth part 2
Outside, also, the backboard 7 by the second trip bolt be arranged on fixture 1 on, to fastening to internal tooth part 2
Position.
