[0033] The working principle and use process of this utility model:

[0034] The stator of the conversion motor is placed on the operating table 1, and the equipment is turned on so that the lower end of the hydraulic cylinder 3 pushes the cutter assembly 4 to move downward slowly, and the cutter part 43, the limit guide assembly 42 and the adjusting member 41 can be pushed downward slowly as a whole through the connecting shaft 45 and the linkage frame 441. When the bottom of the limit frame 421 contacts the top of the stator, the continuous operation of the hydraulic cylinder 3 can push the connecting shaft 45 to continue to move downward.

[0035] First, rotating the connecting shaft 45 can make the threaded rod at its upper end move up and down inside the lower end of the hydraulic cylinder 3, thereby changing the initial distance between the cutting knife part 43 and the hydraulic cylinder 3, so that its bottom can keep the same distance with the top of the stator of different specifications; then turning any one of the left and right transmission belts 412 can drive the two pulleys 414 to rotate with the cooperation of the transmission belt 412, thereby rotating the two sliders 423, and with the cooperation of the front and rear limit rods, the limit frame 421 can be moved up and down relative to the mounting frame 411, ensuring that enough space is reserved above the guide block 425 for the movement of the cutter head 431; and it can ensure that the bottom of the limit frame 421 can keep the same distance with the top of the stator of different specifications, so that the hydraulic cylinder 3 can always maintain a fixed telescopic length when processing the stator copper wires of different specifications, thereby ensuring that the contact force between the limit frame 421 and the top of the stator is the same and controllable.
