Abstract
The utility model discloses a center positioning mechanism which comprises a cushion block and a center positioning pin inserted in the cushion block. A positioning hole is formed in the cushion block, a hanging platform counterbored hole is formed in the positioning hole, a hanging platform is arranged on the center positioning pin, a center hole is formed in the axis direction of the center positioning pin, a screw counterbored hole is formed in the center hole, and the undersurface of the screw counterbored hole is higher than the end face of the cushion block. By the above mode, the center positioning mechanism is good in positioning effect, high in strength, free of breakage and simple in structure.
Description
Technical field
The utility model relates to alignment pin field, particularly relates to a kind of center positioning mechanism.
Background technology
Existing structure comprises centralized positioning pin and cushion block, and centralized positioning pin is inserted in cushion block, and the screw counterbore of centralized positioning pin and the wall thickness at cushion block place are too thin, insufficient strength, and easily fracture, the active force that can bear is little, can not well complete location work.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of center positioning mechanism, good positioning effect, and intensity is high, can not rupture, and simple in structure, processing cost is low, is beneficial to popularization.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of center positioning mechanism is provided, comprises: cushion block and be inserted in the centralized positioning pin in cushion block; On described cushion block, have locating hole, locating hole is provided with hanging platform counterbore; Described centralized positioning pin is provided with hanging platform; On the axis direction of described centralized positioning pin, have centre bore, centre bore is provided with screw counterbore, and the bottom surface of described screw counterbore is higher than the end face of described cushion block.
Preferably, the diameter of described hanging platform is greater than described locating hole diameter, and hanging platform diameter is less than the diameter of described hanging platform counterbore.
The beneficial effects of the utility model are: the utility model intensity is high, can not rupture.
Brief description of the drawings
Fig. 1 is the structural representation of center positioning mechanism of the prior art;
Fig. 2 is the structural representation of a kind of center positioning mechanism of the utility model;
In accompanying drawing, the mark of each parts is as follows: 1, cushion block; 2, centralized positioning pin; 3, hanging platform counterbore; 4, hanging platform; 5, screw counterbore.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of center positioning mechanism, as shown in Figure 2, comprising: cushion block 1 and be inserted in the centralized positioning pin 2 in cushion block 1; On described cushion block 1, have locating hole, locating hole is provided with hanging platform counterbore 3, and hanging platform counterbore 3 can provide space for the diameter that increases hanging platform 4; Described centralized positioning pin 2 is provided with hanging platform 4, and the diameter of described hanging platform 4 is greater than described locating hole diameter, and hanging platform 4 diameters are less than the diameter of described hanging platform counterbore 3; On the axis direction of described centralized positioning pin 2, have centre bore, centre bore is provided with screw counterbore 5, and the bottom surface of described screw counterbore 5 is higher than the end face of described cushion block 1, and screw counterbore 5 is higher than cushion block, make the hanging platform wall thickness at hanging platform counterbore place thicker, be conducive to improve intensity.With respect to existing structure in Fig. 1, the wall thickness at screw counterbore of the present utility model and hanging platform place is thicker, and intensity is good, is not easy fracture.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
