Description
Technical Field
[0001] The utility model relates to the technical field of positioning jigs for assembling plastic parts, in particular to a positioning jig for assembling plastic parts. Background Art
[0002] A fixture is a large category of tools used in carpentry, ironwork, fittery, machinery, electronic control and some other handicrafts. It is mainly used as a tool to assist in controlling position or movement. Fixtures can be divided into three categories: process assembly fixtures, project testing fixtures and circuit board testing fixtures. When machining plastic parts, the plastic parts need to be placed on the fixture for positioning before machining to improve machining accuracy.
[0003] However, the jigs used in existing plastic parts machining generally rotate the threaded rod manually to clamp the plastic parts through the clamping plates on both sides. However, the plastic parts will gradually become loose during the machining process, and the jigs need to be frequently adjusted, which greatly increases the working time of manpower and is extremely labor-intensive.
[0004] For this reason, a positioning fixture for assembling plastic parts is proposed. Utility Model Content
