Self-clamping spring collet application

The collet chuck is a more commonly used clamping tool in machining. It is usually used to loosen and lock the thread at the end of the collet to clamp and loosen the workpiece. This is a cumbersome part of the large-volume, simple-cutting parts, such as the end-faced drilling parts of Figure 1 and the end-faced and drilled parts shown in Figure 2. The labor intensity of the workers is large and the benefits are not high. for
