[0002] Turning, also known as lathe processing, is a part of mechanical processing. It mainly uses a turning tool to cut the rotating workpiece to process the inner and outer cylindrical surfaces, end faces, conical surfaces, forming surfaces and threads of the workpiece. The turning clamping device is a special process equipment used to ensure that the machined parts have a relatively correct position between the lathe and the tool. The turning fixture is usually installed at the front end of the spindle of the lathe and rotates with the spindle.

[0003] During the use of the existing turning clamping device, the staff manually adjusts the inner diameter of the clamp at a slow speed, and the part fixing efficiency is low. At the same time, the turning stress during the rotation of the clamp will cause the clamp to vibrate, affecting the dimensional accuracy of the part and causing a decrease in product quality. Therefore, a clamping device that effectively reduces the turning stress is proposed. Utility Model Content
