A control box 5 is installed in the middle of the top of the bottom plate 3. A micro air pump 18 is installed at the inner bottom of the control box 5. The output end of the micro air pump 18 is connected to the inside of the two airbags 12 through a connecting pipe 7. The input end of the micro air pump 18 is connected to the outer surface of the control box 5 through an air extraction pipe 17. There are a total of seventy positioning pins 8, and the seventy positioning pins 8 are equally divided into two groups. The two groups of positioning pins 8 are evenly distributed inside the moving box 10. The thread insert is positioned by the provided positioning pins 8.

[0024] The working principle of a clamping device for thread insert processing based on Embodiment 1 is: After installing the present invention, place the thread insert in the middle of the clamping seat 1. Start the micro air pump 18. After evacuating the external air through the micro air pump 18 and the air extraction pipe 17, it is delivered to the airbag 12 through the connecting pipe 7.
