[0002] In the field of mechanical transmission, double gears are widely used in key areas such as automobiles, aerospace, and industrial automation due to their compact structure and high transmission efficiency. As manufacturing demands for product performance increase, the standards for machining accuracy and efficiency are becoming increasingly stringent. Currently, double gear machining employs the traditional method of machining one end at a time, i.e., machining one end of the gear first, then switching to the other end for machining. This method requires machining one end at a time, leading to inconsistent machining accuracy at both ends of the double gear and making it prone to errors. Furthermore, the multiple clamping and machining operations further increase the possibility of errors, raising production costs. Additionally, this machining method is time-consuming and has low efficiency. Summary of the Invention
