[0027] Reference Figure 1-Figure 5The structural schematic diagram of the new bearing grinding tool provided by the utility model includes a workpiece clamp 2, a movable bracket 3 and a grinding assembly 4 arranged on a workbench 1. The grinding assembly 4 is slidably arranged on the movable bracket 3 up and down, and the grinding assembly 4 is locked with the movable bracket 3 by a fastening screw 5. The movable bracket 3 is horizontally slidably arranged on the workbench 1, a linear rail 10 is arranged on the workbench 1, and a slider 11 is arranged at the bottom of the movable bracket 3. The movable bracket 3 is slidably connected to the linear rail 10 through the slider 11. In addition, the movable bracket 3 can drive the grinding assembly 4 to move it above the workpiece fixture 2. An arc groove 201 is provided on the side of the workpiece fixture 2. Both sides of the arc groove 201 extend to the top surface of the workpiece fixture 2. A positioning screw 6 extending to the arc groove 201 is vertically provided on the workpiece fixture 2. When the bearing 13 is used to be inserted into the arc groove 201, the bearing 13 is fixed in the arc groove 201 by locking the positioning screw 6, keeping the cross-section of the bearing 13 on the same horizontal plane. In this embodiment, a hole is provided in the middle of the bearing 13, and the positioning screw 6 can be directly inserted into the hole to fix it without the need for further positioning.
[0028] The mobile support 3 has a gantry structure, providing greater stability. The grinding assembly 4 slides vertically in the center of the mobile support 3, ensuring a stable connection between the mobile support 3 and the grinding assembly 4. The grinding assembly 4 comprises a support block 401 and a grinding head 402 mounted at the bottom of the support block 401. The support block 401 is slidably connected to the mobile support 3, while the grinding head 402 performs the grinding operation. A fastening screw 5 passes through the mobile support 3 and presses against the support block 401, locking it in place. This allows the height of the grinding assembly 4 to be adjusted by controlling the fastening screw 5.
[0029] Combine Figure 2 and Figure 5 As shown, a gear 7 is rotatably provided on the movable bracket 3, and a rack 8 is provided on the side of the support block 401 in the vertical direction. The gear 7 is meshed with the rack 8 for transmission, and the gear 7 is driven to rotate by a coaxial handle 9. By turning the handle 9, the gear 7 can be controlled to drive the support block 401 to rise and fall, thereby improving the convenience of operation.
[0030] See Figure 3 The workpiece fixture 2 is also provided with a limit pin 12 extending to the notch of the arc groove 201. The limit pin 12 is provided to prevent the bearing shell 13 from falling off. When the bearing shell 13 is separated from the fixation of the positioning screw 6, the limit pin 12 plays a secondary protection role.
[0031] Working principle:
[0032] During use, insert the bearing 13 into the arc groove 201 from the side of the workpiece fixture 2, then fix the bearing 13 in the arc groove 201 by locking the positioning screw 6, and insert the limit pin 12 to prevent the bearing 13 from falling off, then rotate the handle 9 to adjust the height of the grinding assembly 4, and after the adjustment is complete, use the fastening screw 5 to fix the grinding assembly 4, and finally push the slider 11 to make the grinding head 402 of the grinding assembly 4 rub against the exposed cross-section of the bearing 13 for grinding and polishing.
[0033] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
