AI Technical Summary

Technical Problem

In existing technologies, when machining threaded workpieces, the chuck is prone to causing damage to the workpiece surface and unstable positioning, which affects machining accuracy and appearance.

Method used

The device employs a self-locking center, which uses a self-locking threaded sleeve and a self-locking center wedge to lock the workpiece axially and radially by combining internal thread turning and conical surface friction resistance, thus avoiding direct contact between the chuck and the workpiece.

Benefits of technology

It achieves damage-free clamping, improves machining stability, and ensures thread machining accuracy and appearance quality.

Abstract

A non-damaging self-locking center device for machining threaded workpieces includes a chuck, jaws, a self-locking center device, a workpiece, and a tailstock center. The self-locking center device includes a self-locking threaded sleeve and a self-locking center. The self-locking threaded sleeve has an internal thread end, which connects to the workpiece. The self-locking threaded sleeve and the self-locking center are wedge-fitted, and the self-locking center is drivenly connected to the jaws. The design of the self-locking threaded device avoids direct contact between the jaws and the workpiece, solving the problem of workpiece surface damage affecting appearance and dimensional accuracy, while also improving clamping stability.
