In order to meet the transmission requirements of products, many existing gears need to undergo structural changes; for example, the auxiliary box drive gear in the automotive field is a complex gear. The entire manufacturing process of this gear is very complicated and requires more than a dozen processes to complete. With the advancement of technology, the existing auxiliary box drive gear processing equipment and processing methods can basically meet its processing requirements.

[0003] However, the hard turning process for machining each end face often fails to achieve the desired position due to the positioning and the center of gravity of the gear, and the machining of the internal splines is also very limited. Therefore, due to the complexity of its structure, the fixtures and machining tools are frequently replaced during the machining process, which affects the machining accuracy and efficiency as a whole.

[0004] Therefore, how to provide an efficient and high-precision processing device and method for the auxiliary box drive gear is a problem that technical personnel in this field urgently need to solve. Summary of the invention
