Description

Technical Field

[0001] The present application relates to the technical field of stator and rotor processing, and in particular to a structure for automatically removing burrs from stator and rotor cores. Background Art

[0002] The stator and rotor cores are important components of motors or generators. The stator core is responsible for forming the magnetic flux circuit of the motor and fixing the stator coil. It is part of the motor's magnetic circuit. The rotor core, together with the stator core and the air gap between them, constitute the complete magnetic circuit of the motor. The stator core is usually punched and laminated from silicon steel sheets. It has an insulating layer on the surface and evenly distributed slots on its inner circle for embedding the stator winding. The function of the rotor core is to enhance the magnetic flux of electromagnetic induction, fix the magnetic field, and ensure the normal operation of the motor. The processing technology of the stator and rotor cores includes removing burrs on their surfaces.

[0003] According to the announcement number: CN216608365U, a highly efficient deburring device for a motor stator and rotor is disclosed. This technology discloses "including a mounting box, a controller is fixedly connected to the upper surface of the mounting box, a feed port and a discharge port are respectively opened on both sides of the mounting box, and a discharge pipe is fixedly connected between the feed port and the discharge port, etc., which has the advantages of being able to realize automatic deburring, simple and convenient operation, improving the efficiency of deburring the motor stator and rotor, protecting the stator and rotor while limiting the stator and rotor, avoiding friction between the stator and rotor and other structures, and adjusting the deburring mechanism, and being applicable to the stator and rotor of various specifications of motors, etc.";

[0004] With regard to the above-mentioned related technologies, the inventor believes that the existing automatic burr removal structure of the stator and rotor core is not convenient for fixing stator and rotor cores of different sizes. Since the sizes of different motors and generators are different, the sizes of the stator and rotor cores are also different. If only a single size of stator and rotor core can be clamped, it will have limitations, and if the core is not fixed, the quality of deburring will be affected. Moreover, most deburring structures are not convenient to rotate, and are usually simple contact friction. In this way, the contact strength between the deburring structure and the surface of the core is low, and the burrs in some positions may not be removed cleanly. Therefore, an automatic burr removal structure of the stator and rotor core is needed to solve the above problems. Utility Model Content
