AI Technical Summary

Technical Problem

Existing parts processing and positioning fixtures are difficult to ensure the machining accuracy of thin-wall annular shell parts, and conventional clamping methods cannot ensure that the parts are damaged, which affects their use.

Method used

A combined tooling for thin-walled shell parts is designed, including machining parts and combined tooling. The machining parts are composed of an annular shell, a finishing part and a support collar. The combined tooling is composed of a base, a sleeve, a mating body and a fixture. The support collar of the machining parts is clamped through the sleeve and the mating body, and the support collar is locked by the fixture to achieve stable fixation of the parts.

Benefits of technology

It greatly reduces the risk of precision size of thin-wall annular shell parts, improves processing efficiency, ensures damage-free fixation of parts, and is suitable for actual production and processing.
