Description

Technical Field

[0001] The utility model relates to the technical field of bearing grinding devices, in particular to a grinding machine for bearing production. Background Technique

[0002] Bearing grinding is a processing process aimed at improving the surface hardness and geometric accuracy of bearings, thereby extending their service life and improving operating efficiency. Bearing grinding finely processes the inner ring, outer ring, and raceway of the bearing through precise mechanical operations to ensure accurate geometric shape, smooth surface, and required hardness and wear resistance.

[0003] According to the publication number CN220128484U, a grinding machine for bearing production is provided, belonging to the field of bearing grinding machines, including a box body. A protective ring is arranged on the upper surface of the box body. A clamping turntable is installed on the upper surface of the box body through a bearing. A frame is arranged above the box body, and the frame straddles above the protective ring. A hydraulic cylinder is vertically installed on the upper surface of the frame. The output end of the hydraulic cylinder is installed downward with a mounting rod, and the mounting rod penetrates through the frame. The mounting rod and the center of the clamping turntable are on the same vertical line. A conical cylinder is arranged at the bottom of the mounting rod, and a mounting disk is arranged at the bottom of the conical cylinder. Slide rods are symmetrically and slidably installed inside the mounting disk, and the slide rods penetrate through the outer arc surface of the mounting disk. The feeding during the grinding work is realized by the energy storage of the internal spring, and the threshold value can be set according to the grinding size. When the grinding is in place, the grinding head no longer feeds, realizing the automatic stop effect after reaching the position, and the structure is simple and easy to operate.

[0004] This patent realizes the grinding process of bearings. When the bearing reaches the grinding size threshold, the automatic stop device improves the convenience during bearing grinding. However, before grinding the bearing, the bearing is clamped by the clamping turntable, but the clamping turntable can only clamp the outer wall of the bearing and does not limit the top of the bearing. This causes a deviation between the bearing and the clamping turntable in the vertical direction during bearing grinding, and even the situation where the bearing detaches from the turntable. Therefore, a grinding machine for bearing production is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a grinding machine for bearing production to solve the problem that the traditional clamping only limits the outer wall of the bearing and does not limit the top of the bearing, resulting in vertical movement during bearing grinding as mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A grinding machine for bearing production, including a workbench, a placement table is provided at the top of the workbench, and a fixing frame is fixed to the top of the workbench by bolts. The fixing frame is located at one end of the placement table; a clamping mechanism is provided inside the placement table. The clamping mechanism is used to automatically clamp and limit the bearing and limit the top of the clamped bearing. The clamping mechanism includes a moving block slidably sleeved inside the placement table. One end of the moving block penetrates to the outside of the placement table, and a clamping plate is fixed to one end of the moving block by bolts. A limiting plate is provided at the top of the placement table. The limiting plate is located on one side of the clamping plate. The bottom end of the limiting plate is fixed to a moving seat by bolts, and the moving seat extends into the placement table.

[0007] Preferably, a connecting rod is fixed to one side of the moving block by bolts. One side of the connecting rod away from the moving block is connected to an electric telescopic rod by bolts, and the electric telescopic rod is fixed to the inner wall of the placement table by bolts.

[0008] Preferably, a limiting rod is slidably sleeved inside the connecting rod, and both ends of the limiting rod are fixed to the inner wall of the placement table by bolts.

The limiting rod 4021 is used to support the connecting rod 402, thereby ensuring the stability of the horizontal movement of the connecting rod 402;

[0024] One end of the output end of the electric telescopic rod 401 is connected with a sliding seat 405 through a coupling. A sliding rod 406 is slidably sleeved inside the sliding seat 405. The bottom end of the sliding rod 406 is fixed with a moving rod 407 through bolts. One end of the moving rod 407 is connected with a moving seat 408 through bolts. The movement of the output end of the electric telescopic rod 401 can drive the sliding seat 405 to move. The movement of the sliding seat 405 can squeeze the sliding rod 406 to move.
