AI Technical Summary

Technical Problem

Existing methods for machining valve sleeve reference grooves require frequent tool disassembly, leading to accumulated errors in the positioning reference. Furthermore, traditional tool adjustment methods are slow to respond and have unstable accuracy, making it difficult to meet the requirements of high-consistency mass production.

Method used

The cutting depth is adjusted by controlling the engagement state of the toothed plate with a screw. The toothed plate is disengaged and the blade position is moved by loosening the positioning nut and rotating the screw. With the help of symmetrically arranged double cutting blades and a placement table, the double valve sleeves can be processed synchronously.

Benefits of technology

It enables rapid and precise adjustment of cutting depth, improves processing accuracy and efficiency, avoids positioning errors, and meets the production needs of valve sleeves of different specifications.
