Fatigue stress testing method for clamp

The invention discloses a clamp fatigue stress test method, which comprises the following steps: step 1, preparation for detection: extracting a collet chuck to be detected, clamping a shaft in the collet chuck, clamping the collet chuck in a collet chuck pneumatic clamping seat in detection equipment, and clamping a plurality of collet chucks through the collet chuck pneumatic clamping seat, and relates to the technical field of clamp test. According to the method for testing the fatigue stress of the clamp, a plurality of collets are fixed in times, then thrust and tension tests are carried out at the same time, after the tests are completed, the collets can be rapidly exchanged, different test contents can be carried out, the method is easy to operate and convenient to use, the test effect is good, and only the collets need to be manually loaded. 本发明公开了一种夹具疲劳应力测试方法，步骤一、准备检测：将需要检测的筒夹抽取出来，然后将轴夹持在筒夹内，然后将筒夹夹持在检测设备内的筒夹气动夹持座内，将多个筒夹均通过筒夹气动夹持座夹持，本发明涉及夹具测试技术领域。该一种夹具疲劳应力测试方法，次性对多个筒夹进行固定，然后同时进行推力和拉力的测试，并且在测试完成后，可以快速进
