[0002] With more and more types of parts nowadays, the possibility of CNC machine tools processing a single product for a long time is relatively small. At the same time, the labor cost is getting higher and higher. Increasing output per unit time is a common practice. However, in the current actual situation, one person operates one machine, and part of the time is used for essential repetitive work such as clamping.

[0003] After searching, for example, a Chinese patent number CN206445585U provides a universal blanking structure for CNC machine tools. Although the device realizes the automation of blanking by setting relevant structures and improves the blanking efficiency, it sets an annular reset spring, and the two clamping arms are closed under the action of the annular reset spring, so that the chuck clamps the material. However, as the device is used, the reset spring will be damaged due to its repeated contraction. Once the reset spring is damaged, it is difficult to achieve the automatic clamping function, which affects the service life of the device and its practicality. Therefore, a blanking mechanism for long and short shaft workpieces is proposed to solve the above problems. Utility Model Content
