[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] In the embodiments, by Figure 1-4 A grinding machine for bearing processing is provided, comprising a motor 1, a connector 2 fixedly connected to the output end of the motor 1, a diamond grinding head 3 fixedly connected to the bottom end of the connector 2, handles 4 fixedly connected to both the left and right ends of the motor 1, and a guide mechanism 5 provided at the front end of the motor 1 for guiding the motor 1 when it moves up and down.

[0015] With the above settings, the bearing to be ground is firmly clamped in a special fixture or worktable, ensuring that the grinding position (usually the end face) is stable and easy to operate. The positioning of the inner or outer ring of the bearing (depending on the grinding area) must be accurate. Start the motor 1 to make the diamond grinding head 3 rotate at high speed. Press down or adjust the handles 4 on both sides so that the diamond grinding head 3 is against the surface to be ground. The operator holds the handles 4 on both sides with both hands to keep the equipment stable. The operator applies uniform, controllable pressure perpendicular to the surface to be ground on the grinding machine through the handles 4. At the same time, using the guiding sliding action of the guide mechanism 5 on the reference plane, the operator moves the entire grinding machine in a straight line along the direction defined by the guide mechanism 5. The rotating cutting edge of the diamond grinding head 3 grinds the bearing surface, and the handle 4 provides the operator with a means to apply pressure and stabilize the equipment. This grinder is equipped with a guide mechanism 5, which solves the core problem of difficulty in controlling the accuracy of manual grinding equipment during finishing. It significantly improves the geometric accuracy (flatness, parallelism) and surface quality (roughness) of bearing end face grinding, while improving operational stability, efficiency and grinding head life. It is particularly suitable for high-quality manual grinding and maintenance of critical positioning surfaces of bearings.

[0016] Reference Figure 1-4 The guide mechanism 5 includes a mounting plate 51. The top of the motor 1 is fixedly connected to the mounting plate 51. Two guide sleeves 52 are fixedly connected to the inner side of the mounting plate 51. Guide posts 53 are slidably connected to the inner side of each of the two guide sleeves 52. The bottom ends of the two guide posts 53 are fixedly connected to the bottom plate 54. The top ends of the two guide posts 53 are fixedly connected to the top plate 55. A reset mechanism 56 is provided between the top plate 55 and the mounting plate 51. A locking mechanism 57 is provided at the top end of the right guide sleeve 52. With the above structural setup, the operator can slide the guide sleeve 52 along the guide post 53 by pressing down / lifting the handle 4, adjusting the diamond grinding head 3 to a suitable height. If this height needs to be fixed (e.g., as a safety height or a specific depth), the locking mechanism 57 can be tightened. The operator securely places the base plate 54 (or fixes it with a clamp) on the bearing's reference surface (such as the bearing's inner ring end face, outer ring end face, or clamp platform). The base plate 54 serves as the reference for the entire guide mechanism 5. The operator applies downward pressure by using the handle 4 to overcome the spring force of the reset mechanism 56. The pressure is transmitted to the guide sleeve 52 through the mounting plate 51, forcing the guide sleeve 52 to slide downward along the stationary guide post 53. The diamond grinding head 3 contacts the bearing surface. While maintaining downward pressure, the operator uses the precise linear guide provided by the guide mechanism 5 to move the entire device parallel to the direction of the guide post 53 (vertical direction). The precise fit between the guide sleeve 52 and the guide post 53 ensures absolutely vertical linear movement without any lateral offset or wobbling. When the grinding head reaches the desired grinding depth (which can be determined through trial grinding or measurement), the operator tightens the locking mechanism 57, locking the right guide sleeve 52 and guide post 53. This ensures that the grinding depth remains constant throughout the entire subsequent grinding stroke, even if the pressure applied by the operator fluctuates slightly, allowing for multiple up-and-down linear movements ("feed"), and, if necessary, fine-tuning the lateral position to cover the entire grinding surface. The locking depth of the locking mechanism 57 remains constant. When the grinding head needs to be lifted back to the starting point after completing a downward stroke, the operator reduces the downward pressure, and the spring force of the reset mechanism 56 automatically pushes the mounting plate 51 (and the grinding head) upward, detaching it from the workpiece surface or returning it to the set height.

[0017] Reference Figure 1-4 The reset mechanism 56 includes a hook 561. The mounting plate 51 and the top plate 55 are fixedly connected to each other on opposite sides. A reset spring 562 is connected between the two hooks 561. With the above-described structure, the return spring 562, upon pressure release, provides near-instantaneous upward rebound through its contraction force, ensuring the grinding head detaches from the workpiece surface immediately. This is faster and more reliable than gravity-based reset (such as some designs without springs or with only compression springs), especially for lighter equipment or horizontal / inverted operations, significantly accelerating the "tool lifting" speed, shortening non-grinding time, and improving overall operating efficiency.

[0018] Reference Figure 1-4 The locking mechanism 57 includes an ear block 571. The top end of the right guide sleeve 52 is fixedly connected to the ear block 571. The ear block 571 is slidably connected to the outside of the right guide post 53. A gap 572 is opened on the ear block 571. A threaded hole 573 communicating with the gap 572 is opened on the ear block 571. A screw 574 is threadedly connected to the inside of the threaded hole 573. An extension handle 575 is fixedly connected to the outside of the screw 574. With the above structural design, when the screw 574 is unscrewed or loosened, the gap 572 remains naturally open, and there is a gap between the inner diameter of the lug 571 and the guide post 53. The lug 571 can slide freely along the guide post 53. The operator rotates the extended handle 575 to tighten the screw 574, and the screw 574 is screwed into the threaded hole 573. Its end (or designed with a pressure block) presses towards the gap 572. The pressing action of the screw 574 forces the lug 571 to undergo elastic deformation at the gap 572 (generating radial compression). After deformation, the inner diameter of the lug 571 decreases, generating a strong clamping force (static friction) with the surface of the guide post 53. Locked state: When the screw 574 is fully tightened, the friction generated by the elastic deformation is sufficient to lock the relative movement between the lug 571 (and the entire guide sleeve 52) and the guide post 53. At this point, the right guide sleeve 52 can no longer slide up and down along the guide post 53, and the height of the mounting plate 51 (and diamond grinding head 3) is firmly fixed; unlocking process: rotate the extended handle 575 in the opposite direction, unscrew the screw 574, the elasticity of the ear block 571 causes it to return to its original deformation, the gap 572 opens, the clamping force disappears, and the guide sleeve 52 resumes free sliding along the guide post 53.

[0019] Reference Figure 1-4 Among them, the bottom plate 54 has a groove 6; With the above structural design, the positioning reference core interface groove 6 is designed to precisely fit and fit the end protruding edge of the bearing ring (mainly the inner or outer ring), realize the self-positioning of the equipment, ensure the precise meshing between the guide system and the bearing reference, and improve the rigidity of the system.
