The clamping process is very cumbersome and the processing efficiency is extremely low. During this process, different calibration errors for each product often cause the concentricity of the outer circle and the inner hole, and the perpendicularity of the inner hole and the end face to exceed the dimensional tolerance, affecting the product quality and the clamping time is relatively long; greatly reducing the product processing efficiency. Therefore, a contact type quick clamping and positioning device is proposed for the above problems. Content of the Utility Model
