Problems solved by technology

However, when the mechanical equipment is in normal operation, mechanical vibration will inevitably occur, and the existing positioning pins are usually cylindrical pins. When the mechanical vibration is too large, the positioning pin will loosen and slowly come out of the positioning hole, making Failure of mechanical equipment affects the continuity and stability of mechanical equipment work, and also affects production efficiency

Abstract

The invention discloses a locating pin, which comprises a locating pin body, wherein a reversed 'T'-shaped slot is arranged in the locating pin body, 'I' portion of the 'T'-shaped slot is a threaded hole which is communicated with outside, holes communicated with outside are bilaterally symmetrically arranged in a '-'portion of the 'T'-shaped slot, diameter of each of the holes is smaller than that of the '-' portion of the 'T'-shaped slot, each of the holes is provided with one of ejector blocks, each of the ejector blocks is provided with a lug to prevent the ejector block from being out of the hole, a threaded rod is arranged in the threaded hole, and a sealing element is arranged blew the threaded rod. When the locating pin is used, the threaded rod is in a clockwise rotation and the threaded rod is rotated into the threaded hole, air in the reversed 'T'-shaped slot is extruded by the threaded rod so as to produce an outward pushing force for the ejector blocks in the holes, the ejector blocks are in contact with the locating holes, thereby even though mechanical vibration is produced during a normal operation of mechanical equipment, the locating pin is prevented from being out of the locating holes, and the stability and the continuity of mechanical equipment operating and the production efficiency are improved.

Description

technical field [0001] The invention relates to a positioning pin, in particular to a positioning pin which cannot escape from a positioning hole due to mechanical vibration, and belongs to the technical field of devices for connecting or fixing components or machine parts. Background technique [0002] In mechanical equipment, positioning pins run through the positioning holes of parts that need to be fastened or connected, mainly for fixing purposes, and can also be used to connect mechanical parts. However, when the mechanical equipment is in normal operation, mechanical vibration will inevitably occur, and the existing positioning pins are usually cylindrical pins. When the mechanical vibration is too large, the positioning pin will loosen and slowly come out of the positioning hole, making Failure of mechanical equipment affects the continuity and stability of mechanical equipment work, and also affects production efficiency.
