AI Technical Summary

Technical Problem

Existing micro-flow valve cores suffer from poor machining accuracy and stability due to the poor rigidity of slender shafts and improper clamping methods during processing, making it difficult to meet high-precision requirements.

Method used

A clamping fixture for machining a V-shaped flow channel groove of a small flow valve core is adopted. Through the multi-stage fixing structure and the V-shaped groove design of the support pad, the valve core is firmly fixed. Combined with a high-precision base groove and an adjustable tool bar, the valve core is stably supported and accurately clamped.

Benefits of technology

It improves the machining accuracy and stability of valve cores, simplifies clamping operations, enhances machining efficiency and versatility, and adapts to the machining needs of valve cores of different specifications.
