AI Technical Summary

Technical Problem

In the existing flange processing method, when the tool comes into contact with the flange, it is easy to cause the position of the flange to be offset, resulting in inaccurate position accuracy and verticality of the bolt hole.

Method used

A flange processing positioning device is designed, adopting a bidirectional locking structure, and a bidirectional locking structure is formed by a symmetrically arranged one-way locking assembly, and the clamped flanges are locked from two directions to avoid deviation of the flange.

Benefits of technology

The stable clamping positioning of the flange is achieved, avoiding the flange offset during processing, and improving the position accuracy and perpendicularity of the bolt hole.
