[0035] In order to better understand the present invention, the following Figure 1 - Figure 4 The working principle of the technical solution of the utility model is described in detail:

[0036] When in use, by manipulating the second rotating driving member 224, the second rotating driving member 224 can drive the driving gear 223 to rotate forward, and the forward rotation of the driving gear 223 will drive the driven gear 222 to rotate reversely, thereby driving the rotating shaft 221 to rotate reversely, and the reverse rotation of the rotating shaft 221 will drive the rotating table 130 to rotate reversely. Since each of the guide posts 211 is respectively restricted by the corresponding arc groove 131 and the guide groove 112, during the reverse process of the rotating table 130, each of the guide posts 211 can move along the length direction of the guide groove 112, and each of the guide posts 211 can be retracted to each other, thereby allowing each of the clamping sleeves 212 to be retracted to each other, The bearing ring of the outer wall of the grinding wheel is placed on the rotating table 130, and each of the clamping sleeves 212 is located in the inner hole of the bearing ring. Then, by manipulating the second rotating driving member 224, the second rotating driving member 224 can drive the driving gear 223 to reverse. The positive rotation of the driving gear 223 drives the driven gear 222 to rotate forward, thereby driving the rotating shaft 221 to rotate forward. The positive rotation of the rotating shaft 221 drives the rotating table 130 to rotate forward. Since each of the guide posts 211 is respectively restricted by the corresponding arc groove 131 and the guide groove 112, each of the guide posts 211 can rotate along the length direction of the guide groove 112 during the positive rotation of the rotating table 130. The guide columns 211 can be separated from each other, so that the clamping sleeves 212 can be separated from each other, so that each clamping sleeve 212 can be pressed against the inner hole wall of the bearing ring to realize the clamping and positioning of the bearing ring. By manipulating the telescopic driving member 350, the telescopic driving member 350 can drive the moving seat 320 to move in the horizontal direction, so that the moving seat 320 is close to the bearing ring. In the process of the moving seat 320 approaching the bearing ring, it will drive the grinding head 330 to approach the bearing ring until it abuts against the outer wall of the bearing ring. Then, by manipulating the third rotating driving member 340, the third rotating driving member 340 can drive the grinding head 330 to rotate, so as to clamp the bearing ring. The outer wall of the ring is polished. During the process of polishing the outer wall of the bearing ring, the first rotating drive member 120 is controlled so that the first rotating drive member 120 can drive the support platform 110 to rotate, thereby driving the rotating platform 130 to rotate, and then driving the bearing ring to rotate, so as to realize polishing of other positions of the outer wall of the bearing ring. During the process of polishing the outer wall of the bearing ring, the clamping members 210 arranged in each annular direction can clamp and position the bearing ring, thereby ensuring the coaxiality of the bearing ring during the polishing process and improving the polishing accuracy of the bearing ring. In addition, the polishing device can clamp, position and polish the bearing ring within a certain diameter range, and has high applicability.

[0037] The bearing ring grinding device provided by the utility model has the following beneficial effects:

[0038] (1) By manipulating the second rotating driving member 224, the second rotating driving member 224 can drive the driving gear 223 to rotate. The rotation of the driving gear 223 drives the driven gear 222 to rotate, thereby driving the rotating shaft 221 to rotate. The rotation of the rotating shaft 221 drives the rotating platform 130 to rotate. Since each of the guide pillars 211 is restricted by the corresponding arc groove 131 and the guide groove 112, each of the guide pillars 211 can move along the length direction of the guide groove 112 during the rotation of the rotating platform 130. Each of the guide pillars 211 can be retracted or separated from each other to achieve the clamping and positioning of the bearing ring within a certain diameter range.

[0039] (2) By manipulating the telescopic driving member 350, the telescopic driving member 350 can drive the movable seat 320 to move in the horizontal direction, so that the movable seat 320 approaches or moves away from the bearing ring. When the movable seat 320 approaches the bearing ring, it will drive the grinding head 330 to approach the bearing ring until it abuts against the outer wall of the bearing ring, so that the bearing ring within a certain diameter range can be ground;

[0040] (3) During the process of grinding the outer wall of the bearing ring, the bearing ring can be clamped and positioned by the clamping members 210 arranged in each circumferential direction, thereby ensuring the coaxiality of the bearing ring during the grinding process and improving the grinding accuracy of the bearing ring. In addition, the grinding device can clamp, position and grind bearing rings within a certain diameter range, and has high applicability.
