[0002] In the process of motor manufacturing, the motor stator is an important component of motors such as generators and starters. The stator consists of three parts: stator core, stator winding and frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate current.

[0003] During the processing of the motor stator, it is often necessary to fix and clamp it. There are many devices on the market that can clamp the motor stator. For example, the patent publication number is: CN211744279U; the patent name is a patent for a fixing device suitable for servo motor stator processing, which discloses a fixing device suitable for servo motor stator processing, including a support column, the top of the support column is fixedly connected to a processing table, the bottom of the processing table is fixedly connected to a flange, the bottom of the flange is fixedly connected to a motor, the bottom of the flange is plugged with bolts, and the output end of the motor is fixedly connected to a processing turntable. The advantages of the utility model are: through the matching arrangement of the processing turntable, circular hole, steel column, stator, preset groove, cylinder body, piston, clamping plate and groove, the stator can be fixed by two measures, which solves the problem that the existing clamping and fixing effect is not good and affects the stator processing accuracy; through the matching arrangement of the processing turntable, circular hole, steel column, stator, preset groove, cylinder body, air pipe, piston and clamping plate, the adaptability of the fixing device can be improved, which solves the problem that the existing fixing device cannot adapt to stators of various sizes;

[0004] However, in the above-mentioned patent, the steel column needs to be inserted into the circular hole for positioning, but the position of the circular hole is limited. Therefore, in the actual processing process, only the stator corresponding to the circular hole position can be processed and positioned, and the practicality of the device is insufficient. At the same time, the cylinder body and the clamping plate in the above-mentioned patent are fixed in position and cannot rotate with the turntable. Therefore, after the turntable drives the stator to rotate, the groove on the clamping plate cannot match the steel column, which will cause the steel column limit failure. Therefore, a motor stator processing clamping tool is proposed. Utility Model Content
