Neodymium iron boron magnet surface treatment device

Abstract

The invention discloses a neodymium iron boron magnet surface treatment device. The device comprises a base; multiple support legs are arranged under the base; a left side plate is arranged at the left end of the base; a cross beam is arranged at the upper end of the left side plate; an U-shaped cutting groove is formed in the base; a left ejecting screw rod is arranged at the left end of the U-shaped cutting groove, and a right rotating shaft is arranged at the right end; a left ejecting sleeve is arranged on the left ejecting screw rod; a right ejecting sleeve is arranged on the right rotating shaft; a first cutting groove is formed in the upper end surface of the cross beam; a first rotating shaft is rotationally connected into the first cutting groove; a second cutting groove opened atthe lower end is formed in the lower end surface of the cross beam; a polishing module is slidingly connected into the second cutting groove; a rotating shaft sleeve is fixedly mounted on the first rotating shaft; a first gear is fixedly mounted on a conveying screw rod; a second gear is fixedly mounted on the right rotating shaft; and a transmission module is arranged between the conveying screwrod and the first rotating shaft. The neodymium iron boron magnet surface treatment device is simple in structure, high in polishing efficiency and convenient to clean polishing chips.

Description

technical field [0001] The invention relates to the technical field of polishing equipment, in particular to an NdFeB magnet surface treatment device. Background technique [0002] Neodymium magnet (Neodymium magnet), also known as NdFeB magnet (NdFeB magnet), is made of neodymium, iron, boron (Nd 2 Fe 14 B) The formed tetragonal crystals are widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools. [0003] After the NdFeB magnet is manufactured, in order to be more beautiful and prevent corrosion, the surface of the NdFeB magnet will be treated with electroplating, anti-corrosion, anti-oxidation, etc., and the surface of the NdFeB magnet needs to be treated before electroplating. Among them, mechanical polishing is the most commonly used process, and it is the most important link in the surface treatment of NdFeB magnets. As a pre-plating process for NdFeB magnets, the quality of mechanical polishing directly affects th...

Problems solved by technology

[0004] In the polishing process, cylindrical NdFeB magnets are the most difficult to handle, and the traditional surface treatment methods of cylindrical NdFeB magnets usually use hand-held polishing facilities to polish the surface of NdFeB magnets. This process is not only inefficient, but also Moreover, there is a large potential safety hazard. In addition, the polishing process will produce a large amount of polishing debris, and the cleaning process of the polishing debris is also labor-intensive.
