The plunger pump shaft shown in Figure 1 is one of the key components of the oil pump. Due to its singular shape, machining is difficult. To this end, we have designed the sleeve fixture shown in Figure 2, which has been proved by production practice to not only ensure the processing quality of the workpiece, but also greatly improve the work efficiency. First, the processing technology analysis Although the pump shaft is a shaft type workpiece, but there are two axes with the same angle of 6 ° 30 ', the workpiece needs to be quenched and tempered. The process analysis is as follows:
