[0003] Patent publication number CN222511674U discloses a polishing device for an electric rotor. Through the sleeve, arc plate, first threaded rod, thread groove and connecting rod, multiple arc plates can be moved outward at the same time by rotating a first threaded rod, so that it is convenient to support and limit electric rotors with different inner diameters, and the portability during use is improved. However, the polishing process of this scheme often generates a large amount of dust during implementation, especially in the mechanical polishing stage. The abrasive and rotor materials used in the polishing process will be worn under friction to form fine dust particles, which are easy to float in the air. If these dusts are not cleaned and collected in a timely and effective manner, they will have an adverse effect on the working environment and the health of operators. The floating dust will not only cause air pollution, but also may be deposited on the surface of equipment, tools and products in the workplace, affecting the quality and processing accuracy of the products.
