Abstract

The invention belongs to the field of machine tools for grinding or polishing and specifically discloses a polishing mechanism used for a shaft. The polishing mechanism comprises a clamping device, a rack, abrasive belts, a transmission roller, a first drive roller and a second drive roller. The transmission roller is fixedly connected to the rack, the transmission roller is provided with a spiral strip-shaped slot along the roller surface, and the strip-shaped slot is internally provided with a plurality of rollers which are uniformly distributed along the spiral track; and the abrasive belts are arranged along the spiral strip-shaped slot in the transmission roller and matched with the rollers, one end, stretching out of the transmission roller, of each abrasive belt is wound on the first drive roller, and the other end of the corresponding abrasive belt is wound on the second drive roller. According to the polishing mechanism used for the shaft, through specific structures of the spiral strip-shaped slot in the transmission roller and the rollers, inclined arrangement and continuous transmission of the abrasive belts are achieved, through inclined polishing of the abrasive belts, strip-shaped polishing scratches are avoided, polishing is more uniform, and the polishing effect is better; and through intermittent reverse polishing, oneness of polishing textures on the surface of the shaft is avoided, and polishing is more uniform.

Description

technical field [0001] The invention relates to the field of machine tools for grinding or polishing. Background technique [0002] The grinding of the shaft follows the process of rough grinding first, then fine grinding and polishing. Coarse grinding generally uses emery wheels of different particle sizes. If higher particle size grinding is required, precision polishing abrasive belts are often used for polishing. That is, the processed shaft is fixed by the supporting plate, and the workpiece is driven to rotate by the circular motion of the guide wheel towards the supporting plate, and the surface of the shaft is ground by the abrasive belt rotating in the opposite direction. Since the grain size of the abrasive belt is higher than that of the grinding wheel, it is When cutting the shaft, the surface quality is high, and the precision is relatively high. [0003] However, due to the limited width of the existing polishing abrasive belt, it can only process the surface...
