During the grinding process, the screws on the coupling and the bearing seat 9 can be removed first, and then the bearing seat 9 can be pushed to slide away from the grinding motor 2, so that the core shaft 5 is removed with the grinding Brun 7, and then the bearing ring to be ground is put on the grinding Brun 7 and then reinstalled for grinding. In this way, the disassembly and assembly of the bearing ring is more convenient and reliable. Therefore, the bearing ring surface grinding device of this embodiment can use the grinding Brun 7 and Brun baffle 8 to retain the abrasive to simply and effectively achieve high-precision grinding of the bearing ring, use the grinding Brun to grind the inner ring of the bearing ring, and use the Brun baffle 8 to grind the outer ring of the bearing ring.

The end of the lower end of the connecting rod connected to the Brun pressure rod 6 is in the lifting channel, and the connecting rod and the Brun pressure rod 6 form an L-shaped rod structure, so that the air source can be used to push the lifting piston 16 to achieve downward pressure, and the compressibility of the air source can also be used to provide elastic force. In order to facilitate the sliding of the lifting piston 16, in this embodiment, a hemispherical groove is provided to effectively retain the lubricating oil, and the setting of a buffer spring can further avoid the Brun pressure rod 6 from colliding with the lifting channel while being pressed down.
