[0002] In the traditional transmission shaft processing, especially when it comes to keyway milling and drilling processes, there are often positioning problems. The fixing of the transmission shaft usually relies on manual operation, which not only increases the uncertainty in the processing process, but also greatly reduces production efficiency. Since both ends or both sides of the transmission shaft need to be processed by the same process, in the traditional method, after completing the processing on one side, the transmission shaft needs to be manually repositioned and fixed to process the other side. This process is cumbersome and time-consuming. At the same time, the accumulated errors of manual operation make it difficult to control the processing accuracy of the final product, affecting product quality.

[0003] In addition, the limitations of traditional processing methods are particularly obvious for mass production and high-precision products. On the one hand, frequent manual intervention makes it difficult to meet the high efficiency and low cost requirements of modern manufacturing; on the other hand, processing accuracy is restricted by the technical level and working status of the operator, making it difficult to achieve stable quality output.
