Abstract

The invention provides a positioning pin, and belongs to the technical field of machinery. The positioning pin solves the problem that an existing positioning pin is poor in stability. The positioningpin comprises a pin body, positioning grooves are formed in two opposite side walls of the pin body respectively, the two positioning grooves are close to the two ends of the pin body respectively, nitrile rubber is installed in the positioning grooves, the width and the thickness of the nitrile rubber are both smaller than the width and the thickness of the positioning groove respectively, a fastener is fixedly arranged on the nitrile rubber, a part of the fastener protrudes out of the side wall of the pin body, the fastener comprises a fastening part and guide parts extending outwards fromthe two ends of the fastening part, the end surfaces of the two guide parts are both planes, one end of each guide part is provided with a guide-in corner, the outer end of each guide-in corner is slightly lower than the side wall of the pin body, and a round corner is formed between the other end of each guide part and the fastening part. The position pin has the advantages of being simple in structure and good in stability.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a positioning pin. Background technique [0002] Locating pins are commonly used positioning tools in mechanical processing. They are widely used in machining. Ordinary locating pins are generally fixed. However, in high-strength working environments, especially those with severe vibration, locating pins are easy to use. are shaken out, resulting in the failure of the connection between components. Contents of the invention [0003] The object of the present invention is to propose a positioning pin with simple structure and good stability in view of the above-mentioned problems in the prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: a positioning pin, comprising a pin body, characterized in that positioning grooves are respectively opened on two opposite side walls of the pin body, and the two po...
