SWC SWP turning of fork head of universal coupling

In the process of mass production of SWC type universal coupling, if you encounter the processing problem of flannel fork head, fork head is a steel casting, the outer round and the flange end face need to be processed, turning, clamping flange end fork head is no problem, but when turning the flange, there is no way to load the clamp, the lathe four-jaw single chuck can only be two claws, clamping, considering the welding process claw, Because the batch is large, too wasteful, and the design of tooling is not easy, in this case, we came up with a simple and easy method. The fork head is staggered and stacked together to ensure that the fork head gap is equal, and after basically finding no deviation, spot welding into a whole at the 4 solder joints. In this way, the flannel at both ends can be easily inserted and each processing surface can be turned into a lathe.
