[0002] The clamping mechanism of the shaft face milling machine is a device used to fix and clamp shaft parts for face milling. This clamping mechanism needs to ensure the stability and accuracy of the shaft parts during the processing to prevent the workpiece from moving or shaking, thereby improving the processing quality and efficiency.

[0003] In the prior art, the clamping mechanism is usually equipped with a guide rail and a slide seat, but has the following disadvantages when used:

[0004] 1. The debris generated by processing will be scattered on the surface of the guide rail, which will easily affect the travel of the slide after long-term use, thereby affecting the clamping accuracy.

[0005] Therefore, we propose a clamping mechanism for the end milling machine of shaft parts. Utility Model Content
