[0002] The stator is the stationary part of the motor or generator. The stator consists of three parts: the stator core, the stator winding and the frame. The frame is used to fix the core. For a suspended generator, the frame is used to bear the entire weight of the rotating part; the core is part of the generator's magnetic circuit; and the coil forms the generator's circuit.

[0003] Reference Figure 1 The stator 11 windings of the existing motors are mostly wound with multiple strands of wire, and one end where the ends of the wires are concentrated is the cutting end 12 of the stator 11. During the processing of the stator 11, the wires at the cutting end 12 need to be cut as a whole to make the wire ends flat and convenient for welding. In the related art, the cutting machine includes a conveying device and a cutting knife 2. The stator 11 is usually transported and fixed to the cutting knife 2 by the conveying device, and the wires at the cutting end 12 of the stator 11 are cut by holding the cutting knife 2.

However, manually cutting the wires at the stator cutting end is inefficient and consumes labor costs. For this reason, the present application provides a cutting device for a stator cutting machine.

The cutting end 12 of the stator 11 faces downward and is located between the four cutting knives 2.

[0034] The stator 11 is fixed between the four cutting knives 2 by the conveying device, and the telescopic electric cylinder 4 is started. The telescopic electric cylinder 4 drives the cutting knife 2 to move toward the center of the workbench 1, so as to cut off the wire end at the cutting knife 2, and then the cutting knife 2 is reset. After the wire end of an angle is cut, the stator 11 is driven to rise by the conveying device, and then it is lowered after rotating to a specified angle. For example, the stator 11 is fixed by a clamp, and then the clamp is driven to rise and rotate. Any structure that can drive the clamp to rise and rotate can be used. The cutting operation of the cutting knife 2 is repeated until the wire of the cutting end 12 of the stator 11 is cut. The telescopic electric cylinder 4 uses a servo electric cylinder model SEC61-R6425 of Geji (Shanghai) Electromechanical Technology Co., Ltd., which can adjust the position at will, read the shear force, and facilitate the background monitoring data.
