Abstract

The invention relates to a positioning structure. A positioning pin is mounted on a part; an air exhaust device is arranged on the positioning pin; and the air exhaust device communicates with the bottom of the positioning pin. When the positioning structure is assembled, air is exhausted from the air exhaust structure, so that a pin can be accurately assembled to the position, and therefore, the pin is prevented from being extruded out by compressed air.

Description

A kind of location structure
Technical field
The present invention relates to a kind of location structure.
Background technology
In mechanical part, the part that some precision is high only is difficult to reach requirement by bolt location, therefore can be by alignment pin Reach to position purpose, or prevent installation site, anisotropy.When alignment pin and pin-and-hole are interference fit, owing to being the mode of being full of Coordinating, during assembling alignment pin, can extrude the air in pin-and-hole, air is difficult to get rid of, and hinders alignment pin assembling to put in place, after assembling There is the risk that alignment pin is extruded by compressed air.
Summary of the invention
It is an object of the invention to provide a kind of location structure, reached the requirement of location by alignment pin, and dress can be realized The air in pin-and-hole is discharged in timing, it is ensured that alignment pin assembling puts in place, prevents alignment pin from being extruded by compressed air.
The concrete technical scheme of the present invention is that alignment pin is arranged on part, is provided with exhaust dress on described alignment pin Putting, the bottom of exhaust apparatus connection alignment pin, described exhaust apparatus is the axially extending bore arranged on alignment pin.
The present invention is when assembling, and air is discharged from exhaust structure, makes pin accurately to assemble and puts in place, prevents pin quilt Compressed air is extruded.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As it can be seen, a kind of location structure, including alignment pin, described alignment pin 1 is arranged on part 3, described Alignment pin 1 on be provided with exhaust apparatus 2, exhaust apparatus 2 connects the bottom of alignment pin 1, and described exhaust apparatus 2 is fixed The upper axially extending bore arranged of position pin.

Claims (1)

1. a location structure, is characterized in that, described location structure includes that alignment pin, described alignment pin (1) are arranged on zero On part (3), described alignment pin (1) is provided with exhaust apparatus (2), exhaust apparatus (2) connection alignment pin (1) bottom, described exhaust apparatus (2) is the axially extending bore arranged on alignment pin.
