Abstract

The invention provides a positioning pin with the improved structure, and belongs to the technical field of machinery. The positioning pin solves the problem that an existing positioning pin is poor in stability. The positioning pin with the improved structure comprises a pin body, a main oil hole is formed in the pin body in the axial direction of the pin body, a plurality of auxiliary oil holescommunicating with the main oil hole are formed in the side wall of the pin body in the radial direction, a positioning groove is further formed in the side wall of the pin body, nitrile butadiene rubber is installed in the positioning groove, a fastener is fixedly arranged on the nitrile butadiene 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, wherein the two ends of the fastening part extend outwards to form the guide parts, the end surfaces of the two guide parts are both planes, one ends of the guide parts are provided with guide-in corners, the outer ends of the guide-in corners are slightly lower than the side wall of the pin body, and round angles are formed between the other ends of the guide parts and the fastening part. The positioning 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.
