AI Technical Summary

Technical Problem

Existing fixtures are usually only suitable for machining cylindrical thin-walled parts of a single specification, which leads to the need to process fixtures of multiple specifications during small-batch trial production, increasing production costs.

Method used

A fixture comprising a transmission mechanism and an internal support mechanism was designed. The transmission mechanism achieves synchronous expansion and contraction of the support cylinder through a cross slide rail and a spiral guide rail. The internal support mechanism fills the gap between the support cylinders with air bladders to adapt to the support needs of parts of various specifications.

Benefits of technology

It improves the versatility of the fixture, enabling it to process parts of various specifications, significantly reducing production costs and the probability of part deformation.
