Description

Technical Field

[0001] The utility model belongs to the technical field of polishing, and in particular relates to a polishing machine. Background Art

[0002] With the development of the machinery industry, the precision requirements for machinery and parts are getting higher and higher. Therefore, the roughness of the surface, inner hole, dead corner and other parts after processing is high, which is difficult to meet the precision requirements. Grinding and polishing are required. Due to the good polishing effect of magnetic polishing machines, magnetic polishing machines are often used to polish to remove burrs, oil stains, etc. on the surface, pores, dead corners and other parts of the parts. The turntable of the magnetic polishing machine is provided with a magnetic structure that can generate a magnetic field. The rotation of the turntable can drive the movement of the magnetic structure. During the polishing process of the magnetic polishing machine, the magnetic structure on the turntable of the magnetic polishing machine generates a magnetic field, which drives the magnetic needle in the polishing barrel to move through the magnetic field, and then polishes the parts through the magnetic needle. As the polishing progresses, the temperature of the polishing liquid in the polishing barrel will increase, and the heat will be transferred to the turntable under the polishing barrel. The temperature of the turntable will increase. At the same time, the magnet structure will also generate heat during the polishing process, resulting in the temperature of the turntable and the magnet structure to increase, making it difficult to dissipate the heat, affecting the performance of the turntable and the magnet structure.
