Technical Field

[0001] This utility model relates to the field of bearing ring polishing, specifically a bearing ring polishing device. Background Technology

[0002] Polishing equipment is typically used in industrial production for surface treatment. Its main function is to grind and polish the surface of a workpiece through physical or chemical means, giving it a certain degree of smoothness and gloss. This can improve the appearance quality of the product, enhance its surface gloss, and also improve its functional performance.

[0003] Bearing races are components used to support bearings, typically made of metal. Their function is to keep the bearing in the correct position and provide additional support and protection. Races are usually installed around the outer or inner ring of a bearing to ensure the bearing is correctly installed in mechanical equipment and provides stable support during operation.

[0004] Patent application number 202421138979.4 discloses a bearing inner ring polishing device, including a worktable and a polishing wheel disposed above the worktable. The surface of the worktable is provided with a polishing component, which includes a movable disk disposed above the worktable. A fixed disk is rotatably connected to the upper surface of the movable disk. The polishing wheel and the fixed disk are driven to rotate by a motor, which facilitates the polishing operation on the inner side of the bearing ring.

[0005] The aforementioned bearing inner ring polishing device uses a polishing wheel with a constant position and a cylindrical structure to polish the inner ring of the bearing. However, since the polishing wheel needs to be in contact with the inner wall of the bearing inner ring to achieve the polishing function, it is difficult for the bearing ring to fit onto the polishing wheel. Furthermore, as the inner ring of the bearing wears out during polishing, it separates from the polishing wheel, resulting in a poor polishing effect on the inner ring of the bearing. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide a bearing ring polishing device to solve the technical problem that the polishing wheel needs to abut against the inner wall of the bearing inner ring to achieve the polishing function, which makes it difficult for the bearing ring to be fitted onto the polishing wheel, and as the bearing inner ring wears down during polishing, it separates from the polishing wheel, resulting in poor polishing effect on the bearing inner ring.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bearing ring polishing device, comprising a base and a lifting plate disposed in the base, wherein the top of the lifting plate is fixed with a bearing ring body by a clamping mechanism, a turntable is rotatably mounted on the top wall of the base, a sliding groove is provided at the bottom end of the turntable, a sliding frame is inserted into the bottom end of the sliding groove, and a polishing block is installed at the bottom end of the sliding frame, wherein a third electric push rod fixed to the sliding frame is installed on the outer wall of the turntable.

[0008] The present invention is further configured such that a fixing plate is installed at the bottom end of the base, and a first electric push rod connected to the lifting plate is embedded in the fixing plate.

[0009] The present invention is further configured such that mounting plates are fixed on both sides of the top surface of the lifting plate, and the clamping mechanism includes a second electric push rod and a clamping plate embedded in the mounting plate.

[0010] The present invention is further configured such that one end of the clamping plate has an arc-shaped structure that abuts against the outer wall of the bearing ring body, and the other end of the clamping plate is fixedly connected to the second electric push rod.

[0011] The present invention is further configured such that a motor is mounted on the top of the base, and the motor shaft is fixedly connected to the turntable.

[0012] The present invention is further provided that a connecting rod is fixedly installed on the top of the grinding block, and a connecting groove is provided at the center of the connecting rod.

[0013] The present invention is further configured such that the bottom end of the sliding frame is fitted into the connecting groove, and the side wall of the sliding frame is provided with a screw hole, and a bolt threaded into the screw hole is installed on the connecting rod.

[0014] In summary, the present invention has the following beneficial effects: A turntable is rotatably mounted in the base, and a groove is provided at the bottom of the turntable. A third electric push rod on the outer wall of the turntable drives the sliding frame to move in the groove, adjusting the position of the grinding block at the bottom of the connecting rod during the movement. The grinding block rotates eccentrically below the turntable, abutting against the inner wall of the bearing ring body for grinding. As grinding continues, the third electric push rod drives the sliding frame and grinding block to retract, ensuring the grinding block remains in contact with the inner wall of the bearing ring body. This facilitates the movement of the grinding block as the inner wall of the bearing ring wears down, improving the grinding effect on the bearing inner ring. Attached Figure Description
