AI Technical Summary
In the existing technology, during the machining of automotive turbine rotors, the worm gear clamping is unstable and the clamping force is insufficient, resulting in an unstable machining process.
It adopts a worm gear, gear and external gear ring structure. The worm gear drives the worm wheel to rotate, which increases the clamping force. The longitudinal positioning clamping is achieved through the cooperation of the rotating tube, limit frame and spring.
This improves the clamping stability of the worm gear and the stability of machining, ensuring the reliability of the machining process.
