Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a positioning and clamping device for the rough machining process of couplings. Background Technology

[0002] A coupling is a mechanical part used to connect the motor drive component and the output drive shaft so that they rotate together. There are many types of couplings. For couplings where the holes connecting the motor drive component and the output shaft are not on the same axis, the manufacturing process requires initial rough machining (W1 sequence), including machining the holes on the flange circumference and the large center hole. The conventional practice is to clamp the coupling on a general-purpose fixture on a machine tool. However, the structure of these general-purpose fixtures is not perfectly suited for these types of couplings. Therefore, clamping and positioning require repeated adjustments by operators, which is time-consuming and labor-intensive, reducing production efficiency. Furthermore, due to excessive manual intervention, the stability and consistency of the clamping are difficult to guarantee. Utility Model Content
