Description

Technical Field

[0001] The utility model relates to the technical field of bearing grinding processing platforms, in particular to a bearing grinding processing platform. Background Art

[0002] Bearings are an important component in mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. During the production of bearings, the outer and inner surfaces of the inner and outer rings of the bearings are usually ground to ensure smooth surfaces. During the use of the grinding device for bearing processing, both ends are clamped. However, when clamping the bearing ring, both the inner and outer clamps will affect the grinding of the bearing surface. During grinding, it is difficult to adjust the outer and inner surfaces according to demand, which affects the efficiency of bearing processing and grinding.

[0003] A bearing processing grinding device disclosed in the Chinese utility model patent application disclosure CN210435953U solves the problem of adjusting the grinding of the inner surface and the outer surface, but the bearing processing grinding device still has the following disadvantages: First, when the above-mentioned bearing processing grinding device is grinding both sides, the bearing needs to be removed, turned over and then installed for grinding, which is a relatively cumbersome process. In addition, since the temperature of the bearing increases during grinding, it is difficult for workers to take it out, which is not conducive to use; Second, in order to pursue the accuracy of bearing grinding, the grinding head needs to be maintained and replaced after a long period of grinding use, and the process of replacing the grinding head of the above-mentioned bearing processing grinding device is relatively complicated, which wastes time and delays the progress of the project.

The bottom of the auxiliary rod 15 is fixedly connected to the top of the second fixing plate 16. The bottom of the first rotating rod 13 is fixedly connected with a first connecting plate 17, and the first connecting plate 17 is in a square ring shape. The inner top wall of the first connecting plate 17 is higher than the top of the fixed block 6. The width between the inner walls of the first connecting plate 17 is greater than the width of the fixed block 6. The bottom of the first connecting plate 17 is fixedly connected with a second connecting plate 18. The width and shape of the second connecting plate 18 are consistent with those of the first connecting plate 17. The right side wall of the second connecting plate 18 is provided with a first through hole, and the first through hole is located on the lower half of the second connecting plate 18.

[0029] When in use, an existing grinding device for bearing processing needs to remove the bearing, turn it over and then install it for grinding when grinding the front and back sides. The process is relatively cumbersome, and because the temperature of the bearing increases during grinding, it is difficult for workers to take it out, which is not conducive to use. Therefore, there is a bearing grinding processing platform. When the bearing is ground, the telescopic end of the electric telescopic rod 11 extends out, and the bearing is placed in the middle of the second connecting plate 18. The second motor 20 is started, and the second threaded rod 19 starts to rotate, so that the two clamping plates 21 move closer to the middle, and the clamping plates 21 are clamped on both sides of the bearing for fixing. Then the telescopic end of the electric telescopic rod 11 contracts, so that the second connecting plate 18 is close to the right side wall of the fixed platform 4. Because of the setting of the limit groove, the bearing can be firmly clamped in the middle of the clamping plate 21, and then the first motor 8 is started, the first threaded rod 7 starts to rotate, and the clamping block 9 moves from top to bottom, so that the first connecting plate 17 and the second connecting plate 18 cannot move, and the bearing grinding starts. When one side of the bearing is ground, the second threaded rod 7 starts to rotate, and the clamping block 9 moves from top to bottom, so that the first connecting plate 17 and the second connecting plate 18 cannot move, and the bearing grinding starts. The first motor 8 is reversed, and then the block 9 moves from bottom to top, and then the telescopic end of the electric telescopic rod 11 is extended, driving the bearing to move from left to right. When the telescopic end of the electric telescopic rod 11 stops extending, the worker rotates the first rotating rod 13 to turn the bearing over. Through the arrangement of the slide groove 14 and the auxiliary rod 15, the bearing can be smoothly turned over. After the bearing is turned over, the telescopic end of the electric telescopic rod 11 is retracted. After the second connecting plate 18 is fixed again, the second surface of the bearing is ground. The arrangement of the first rotating rod 13 connected to the bottom of the connecting block 12 enables the bearing grinding processing platform to quickly turn over the bearing without removing the bearing, thereby improving work efficiency and facilitating the use of workers. Through the coordinated arrangement of the electric telescopic rod 11, the first rotating rod 13, the auxiliary rod 15 and the block 9, the second connecting plate 18 can drive the bearing to turn over during use, thereby playing a role in quickly turning over the bearing without removing the bearing, thereby achieving the purpose of improving work efficiency and facilitating the use of workers.
