Description

TECHNICAL FIELD

[0002] Couplings, also known as shaft joints, are mechanical components used to connect two shafts or a shaft and a rotating part. During operation, they rotate together with the two parts and do not disconnect under normal circumstances. In some scenarios, they also serve as safety devices to prevent the connected machine parts from bearing excessive loads, thereby providing overload protection. Coupling machining and punching are critical processes that ensure the connection accuracy and transmission performance of couplings. The hole position, diameter, and depth parameters need to be determined based on the coupling model, material, and connection requirements. During the coupling machining and punching process, different hole sizes require frequent replacement of drill bits. However, existing devices lack convenient and quick replacement structures, leading to tedious and time-consuming operations when replacing compatible drill bits. Moreover, it is difficult to ensure the accuracy of drill bit installation during the replacement process, which may result in positioning deviations, affecting the punching quality and increasing maintenance costs. Therefore, we propose a punching equipment for coupling accessories. SUMMARY
