Abstract

A hollow positioning ejection pin comprises a body, wherein the middle of the body is a hollow columnar structure and is in a shape of a large cylinder, the lower portion of the body is in a shape of a small cylinder, and the large cylinder shape and the small cylinder shape are integrated formed and arranged coaxially. An annular boss is arranged at the top of the body, an ejection cap is in buckled connection with the annular boss, the top of the ejection cap is spherical, and the butt joint position between the ejection pin and the body is sealed by adopting an air cushion. High-pressure air can be inflated into the middle of the body, so that the high-pressure air can jack up the ejection cap, and the purpose of separating the positioning ejection pin and a positioned part is achieved.

Description

Hollow location thimble
Technical field
The present invention is a kind of hollow location thimble, belongs to spare parts processing machinery positioning field.
Background technology
Current machining equipment is varied, wherein in the process of location, needs multiple auxiliary equipment, and thimble is exactly wherein a kind of, and thimble often plays the effect of support.So, to locating having relatively high expectations of thimble, the invention provides a kind of location thimble now.
Summary of the invention
The object of this invention is to provide a kind of hollow location thimble, be easy to realize location thimble and be positioned separated between part.
Object of the present invention is carried out specific implementation by the following technical programs:
Hollow location thimble, comprises body, the column structure that wherein middle part of body is hollow, and wherein the middle part of body is great circle column type, and bottom is roundlet column type, and described great circle column type and described roundlet column type are one-body molded and coaxially arrange; The top of body is provided with annular boss, and on described annular boss snapping crown cap, the top of described top cap is spheroidal, and the docking location between top cap and body adopts cushion seals.
The middle part of described body can be filled with gases at high pressure, can make like this gases at high pressure that top crown is opened, and then reaches location thimble and the separated object between part that is positioned.
Accompanying drawing explanation
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the structure chart of hollow location thimble described in the embodiment of the present invention.
The specific embodiment
As shown in Figure 1, hollow location thimble described in the embodiment of the present invention, comprises body, the column structure that wherein middle part of body is hollow, wherein the middle part of body is great circle column type 1, and bottom is roundlet column type 2, and described great circle column type 1 is one-body molded and coaxially setting with described roundlet column type 2; The top of body is provided with annular boss 3, and on described annular boss 3 snapping crown cap 4, the top of described top cap 4 is spheroidal, and the docking location between top cap 4 and body adopts cushion seals.
The middle part of described body can be filled with gases at high pressure, can make like this gases at high pressure that top crown is opened, and then reaches location thimble and the separated object between part that is positioned.
