Description

Technical Field

[0002] Locating pins, which use the workpiece hole as the positioning reference and are involved in limiting the freedom of an object, are used in some mechanical motion equipment and steel structure buildings. In the process of locating pin processing, in order to meet certain usage requirements, it is necessary to grind the locating pin rod or drill a hole at the top of the locating pin rod. In this case, the locating pin needs to be processed secondary. Therefore, a locating pin fixture is needed to clamp and fix the locating pin to avoid the problem of instability of the locating pin during secondary processing.
