[0002] A self-drilling screw is a screw with a self-drilling head at the front end. Screws have been a common invention in people's production and life for thousands of years. In terms of application areas, it is the first invention of mankind. A self-drilling screw is a new invention of people in recent years, also called a self-drilling screw. A positioning device is required to position the self-drilling screw during processing;

[0003] Publication No. CN 217168187 U discloses a positioning device for screw processing, comprising a mounting base plate and a self-drilling screw body, wherein a mounting seat is provided on one side of the mounting base plate, a mounting groove is provided on a side of the mounting seat away from the mounting base plate, and the self-drilling screw body is located inside the mounting groove;

[0004] When it is in use, in the process of clamping and fixing the screws, multiple electric telescopic rods are required to drive the clamping block to move, which makes the initial manufacturing cost of the device high and the energy consumption cost during use high. The device requires workers to manually remove the screws, and the distance between the device and the processing device is close, which makes the operating space of the workers small; therefore, we propose a positioning device for screw processing.

[0015] By adopting the above technical solution, the clamping frame is not easy to interfere with other structures during the rotation process, so the clamping frame is more stable during the rotation.

[0016] As a further improvement of the above solution, the shape of the clamping block is a semicircular arc, and a non-slip rubber pad is provided on one side of the clamping block.

[0017] By adopting the above technical solution, the contact area between the semicircular arc clamping block and the self-drilling screw is increased, so that the clamping effect is better, and the anti-slip rubber pad increases the friction force and improves the protection effect.
