The embodiment of the present application also discloses a main gear shaft manufacturing process, which includes the following steps: put the head 11 into the clamping space 321, clamp the head 11 with the two clamping jaws 33, and process the tail 12 with the clamping jaw 63. , move the head 11 into the clamping space, the clamping device 2 6 clamps the tail 12 , and the tool rest 72 processes the head 11 .

The implementation principle of a main pinion manufacturing process in the embodiment of the present application is as follows: the head 11 and the tail 12 of the main pinion are respectively clamped by the clamping jaws 63 and 33 so that the clamping device 3 can be adapted during clamping. The head 11 and the clamping device 2 6 are adapted to the processed tail 12 to prevent the main gear shaft from shaking during machining, which is beneficial to improving the machining accuracy.

The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be covered by the scope of protection of the present application. Inside.
