Abstract

The invention discloses a self-ejection type positioning pin of a sliding plate. The positioning pin comprises a pin body, a screw rod, a limiting sleeve and a top sleeve; the pin body is detachably inserted into a pin hole of a pin seat; the screw rod is detachably inserted into the pin body; the upper part of the screw rod is detachably propped against the inner upper part of the pin body; the inner wall of the limiting sleeve and the inner wall of the top sleeve are both in threaded connection with the outer wall of the screw rod; the limiting sleeve is located on the upper portion of the top sleeve, the outer wall of the limiting sleeve is in threaded connection with the inner wall of the pin body, the middle of the limiting sleeve detachably abuts against the inner middle of the pin body, and the outer wall of the top sleeve detachably abuts against the inner middle of the pin body. According to the self-ejection type positioning plug pin for the sliding plate, positioning pin abrasion caused by friction factors is overcome, the service life of the pin device is prolonged, time and labor are saved when the sliding plate is opened, and efficiency is high.

Description

technical field [0001] The invention relates to the positioning of soft tooling fixtures for prototype vehicle manufacturing, in particular to a sliding plate self-top positioning pin. Background technique [0002] The positioning pin of the soft tooling sliding plate used in the trial production stage of the existing prototype vehicle is an integrated structure. In the process of building a car, push the sliding plate to clamp it in place, and then insert the integrated pin into the pin hole to play a positioning and fixing role; when unclamping, pull out the pin and push out the sliding plate to complete a positioning. The advantage of this one-piece pin is that it has a simple structure and is easy to process, but this structure has some disadvantages: ①It is difficult to pull out due to friction and other factors in the working state; ②When pulling out the pin, it needs to be knocked out with a hammer, which is time-consuming and laborious ,low efficiency.
