[0025] Working principle of this utility model:

[0026] The utility model is designed to be a rotor core dislocation tooling, which mainly includes three structures: a movable mold frame 1, a fixed mold frame 2, and a cylinder 3. The movable mold frame 1 and the fixed mold frame 2 constitute a split mold frame. The fixed mold frame 2 is fixed on a workbench, and a dislocation block 6 is placed in a groove 5 for fixing. Four or six groups of dislocation blocks 6 are placed according to actual needs. Due to the distribution of tooth grooves 1 7 and tooth grooves 2 8 on the dislocation blocks 6, the dislocation of the rotor block is a fixed angle, so that the rotor core can be dislocated. The operator only needs to align the tooth shape of the rotor with the dislocation tooling, and put the split mold frames together through the cylinder 3. The dislocation blocks 6 on the movable mold frame 1 and the fixed mold frame 2 are relatively distributed, so that the angle positioning of the rotor block dislocation is more accurate after the mold frames are put together.

[0027] In addition, the reserved grooves 9 can be used to store redundant dislocation blocks 6 to avoid omissions and facilitate management.
