Technical Field

[0001] The utility model belongs to the technical field of carbon fiber rotors, and in particular relates to a surface treatment device for a carbon fiber rotor. Background Art

[0002] When the speed of current permanent magnet motors (especially high-speed permanent magnet motors) reaches over 20,000rpm, how to fix the magnets is a research topic for technicians in this field. If the speed is further increased to the ultra-high speed range, the embedded structure will always encounter bottlenecks, so a surface-mounted magnetic pole structure must be used, which is often fixed with a carbon fiber rotor.

[0003] In the process of realizing the utility model, the inventor found that there are at least the following problems in the technology: in the processing of the existing carbon fiber rotor, in order to make the surface smoother and improve the product quality, it is necessary to grind the surface. The grinding head on the current surface treatment device is fixed to the device body and cannot or is not convenient to be disassembled. Therefore, when the grinding head is damaged or when processing carbon fiber rotors of different diameters, it cannot be replaced, which brings great trouble to the processing.

[0004] To this end, we propose a surface treatment device for carbon fiber rotors to solve the above problems. Utility Model Content

[0009] Inner grooves are formed on both sides of the inner cavity of the fixed seat, and a second spring is symmetrically connected to each inner groove, and a positioning rod is connected to the two second springs. One side of the positioning rod abuts against the processing grinding head, and the other side slides out from the fixed seat, so that it is convenient for people to hold the positioning rod.

[0010] Preferably, the motor and the extension shaft are distributed on both sides of the vertical support plate, and the extension shaft is rotatably connected to the vertical support plate; so that the extension shaft can operate stably under the drive of the motor.

[0011] Preferably, a receiving groove is formed on the side of the outer wall of the extension shaft facing away from the vertical support plate, a first spring is fixedly connected to the inner wall of the receiving groove, and a spring block abutting against the sleeve is connected to the first spring; thereby facilitating the stabilization of the sleeve and the carbon fiber rotor.

[0013] Preferably, the bottom of the processing grinding head extends out from the inner cavity of the fixing seat and is designed in an arc shape; thereby facilitating the bottom of the processing grinding head to contact the carbon fiber rotor and perform surface grinding on the carbon fiber rotor when it rotates.

[0014] In summary, the technical effects and advantages of the utility model are as follows:
