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

[0002] Bearings can be divided into sliding bearings and rolling bearings according to their friction properties. Rolling bearings are composed of outer ring, inner ring balls and cages. During the production and processing of existing rolling bearings, one of the production steps is to grind the bearing rings using grinding equipment. Usually, during the grinding process, the bearing rings are fixed in a limited position and then polished using a grinding block.

[0003] Existing bearing ring grinding equipment needs to fix the bearing ring when grinding the bearing ring. However, due to the different diameters of the bearing rings to be ground, different positioning structures need to be replaced for positioning. Moreover, when grinding bearing rings of different diameters, the thickness of the grinding stone will change due to long-term use, and the grinding stone will be inconvenient to contact with the bearing ring.

Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example: Refer to Figures 1 to 4 A bearing ring grinding device includes a positioning ring 1, a limit plate 2 is fixedly installed inside the positioning ring 1, a servo motor 3 is fixedly installed in the middle of the surface of the limit plate 2, a rotating plate 4 is fixedly installed on the output end of the servo motor 3, positioning grooves are opened on both sides of the surface of the positioning ring 1, a friction component 5 is arranged inside the positioning groove, a support rod 6 is fixedly installed in the middle of the surface of the rotating plate 4, mounting grooves are opened on both sides of the surface of the support rod 6, a positioning component 7 is arranged inside the mounting groove, and a bearing ring 8 is arranged on the surface of the rotating plate 4.

[0025] Use the limit plate 2 to install the servo motor 3, and then connect the servo motor 3 to the power supply. Its output end will drive the rotating plate 4 to rotate. When the rotating plate 4 rotates, it will drive the bearing ring 8 fixed by the positioning component 7 to rotate. When the bearing ring 8 rotates, its surface will be fixed in the positioning groove. The friction component 5 is polished.

[0026] Example 1:

[0027] The friction assembly 5 includes a limiting plate 51 fixedly mounted inside the positioning groove. A threaded groove is provided in the middle of the surface of the limiting plate 51. A threaded rod 52 is passed through the internal thread of the threaded groove. One end of the threaded rod 52 is rotatably connected to the friction plate 53. A threaded ring is fixedly mounted on the surface of the limiting plate 51. The inner diameter of the threaded ring matches the diameter of the threaded rod 52. A limiting groove is provided on the surface of the friction plate 53. A wear-resistant pad is provided inside the limiting groove.

[0028] During use, personnel will rotate the threaded rod 52 through the limiting plate 51. When the threaded rod 52 rotates, it will drive the friction plate 53 to move forward. The friction plate 53 will grind the bearing ring 8, and after the thickness of the friction plate 53 becomes thinner, the friction plate 53 can be moved forward to contact the surface of the bearing ring 8.

[0029] Example 2:

[0030] The positioning assembly 7 includes a plurality of telescopic rods 71 ​​fixedly mounted inside the mounting groove. A spring 72 is sleeved on the surface of the telescopic rod 71. A connecting block 73 is fixedly mounted on one end of the telescopic rod 71. A connecting plate 74 is fixedly mounted on the top of the connecting block 73. A resisting block is fixedly mounted on one end of the telescopic rod 71. The diameter of the resisting block is larger than the diameter of the spring 72. The size of the interior of the connecting plate 74 is adapted to the size of the bearing ring 8. The connecting plate 74 is located above the bearing ring 8.

[0031] During use, the personnel presses the bearing ring 8 downward through the positioning ring 1, and then the bearing ring 8 will squeeze the connecting block 73. After the connecting block 73 is squeezed, the spring 72 on the telescopic rod 71 will be squeezed. After the spring 72 is squeezed, it will reset. The telescopic rod 71 will drive the connecting block 73 to move synchronously to both sides. When the connecting block 73 moves, it will drive the connecting plate 74 to move. The connecting plate 74 and the connecting block 73 will position the bearing ring 8.

[0032] Working principle: First, the bearing ring 8 is pressed downward through the positioning ring 1, and then the bearing ring 8 will squeeze the connecting block 73. After the connecting block 73 is squeezed, the spring 72 on the telescopic rod 71 will be squeezed. After the spring 72 is squeezed, it will reset, and the telescopic rod 71 will drive the connecting block 73 to move synchronously to both sides. When the connecting block 73 moves, it will drive the connecting plate 74 to move. The connecting plate 74 and the connecting block 73 will position the bearing ring 8, and then the threaded rod 52 is rotated through the limiting plate 51. When the threaded rod 52 rotates, it will drive the friction plate 53 to move forward, and the friction plate 53 will grind the bearing ring 8. After the thickness of the friction plate 53 becomes thinner, the friction plate 53 can be moved forward to contact the surface of the bearing ring 8. Finally, the servo motor 3 is installed, and then the servo motor 3 is powered on, and its output end will drive the rotating plate 4 to rotate.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
