A bearing bracket 108 is snapped into the inner wall of the connecting clamp 106. The grinding assembly 2 consists of a dust cover 201 on the top edge of the worktable 101, a servo motor 202, a fixing frame 203, a connecting frame 204, a grinding disc 205, a plug rod 206, and a nut 207. The servo motor 202 is fixedly connected to the inner wall of the dust cover 201. The output shaft of the servo motor 202 is fixedly connected to the fixing frame 203. The grinding disc 205 is snapped into the inner wall of the fixing frame 203. Plug rods 206 are snapped into both ends of the fixing frame 203. One end of the plug rod 206 is snapped into the connecting frame 204, and the other end of the plug rod 206 is threaded with a nut 207. The assembly is connected to the worktable 101, the sliding groove 102, the electric push rod 103, and the fixing frame 104. The components—positioning clamp 105, connecting clamp 106, adjusting bolt 107, bearing bracket 108, servo motor 202, and grinding disc 205—are arranged as follows: During use, the operator places the bearing bracket 108 into the positioning clamp 105, rotates the adjusting bolt 107 to move the connecting clamp 106, and the positioning clamp 105 clamps the bearing bracket 108. The servo motor 202 is then activated, causing the grinding disc 205 to rotate. The electric push rod 103 is activated, pushing the fixing frame 104 along the sliding groove 102, bringing the outer surface of the bearing bracket 108 into contact with the grinding disc 205, allowing the grinding disc 205 to grind the area on the outer surface of the bearing bracket 108 that needs grinding. The grinding process involves repeatedly adjusting the bearing bracket 108 to achieve the desired grinding effect. Through the servo motor 202, fixed frame 203, connecting frame 204, grinding disc 205, insert rod 206, and nut 207, the operator can insert the grinding disc 205 into the fixed frame 203, align the connecting frame 204 with the fixed frame 203, insert the insert rod 206 into the groove on the fixed frame 203 and connecting frame 204, and lock the insert rod 206 with the nut 207. This allows the fixed frame 203 and connecting frame 204 to position the grinding disc 205. This setup facilitates the disassembly and replacement of damaged grinding discs 205, ensuring effective grinding of the bearing bracket 108.

[0023] A support column 3 is fixedly connected to the bottom edge of the workbench 101, and a base 4 is fixedly connected to the bottom of the support column 3. Through the arrangement of the workbench 101, the support column 3 and the base 4, the support column 3 and the base 4 provide stable support for the workbench 101 during use.

[0024] A circular slot is provided at the bottom of one end of the fixing frame 104. An auxiliary rod 5 is slidably connected to the inner wall of the circular slot. With the fixing frame 104 and the auxiliary rod 5, the auxiliary rod 5 can stabilize the movement of the fixing frame 104 during use.

[0025] An auxiliary groove is provided at the other end of the top of the workbench 101. The two ends of the inner wall of the auxiliary groove are fixedly connected to the two ends of the auxiliary rod 5. With the setting of the workbench 101 and the auxiliary rod 5, the auxiliary rod 5 is installed in the auxiliary groove on the workbench 101 during use.

[0026] An adjustment groove is provided at the other end of the top of the fixing frame 104. One end of the inner wall of the adjustment groove is rotatably connected to one end of the adjustment bolt 107. With the setting of the fixing frame 104 and the adjustment bolt 107, when in use, one end of the adjustment bolt 107 rotates in the rotation groove at one end of the inner wall of the fixing frame 104.

[0027] The inner wall of the connecting frame 204 is provided with a slot, and the inner wall of the slot is engaged with the outer surface of the grinding disc 205. Through the setting of the connecting frame 204 and the grinding disc 205, when in use, the grinding disc 205 is engaged in the slot on the inner wall of the connecting frame 204 and the fixing frame 203, and the grinding disc 205 is stably installed.

[0028] In this invention, the working steps of the device are as follows:

[0029] First step: The worker places the bearing bracket 108 into the positioning clamp 105, rotates the adjusting bolt 107 to move the connecting clamp 106, and uses the positioning clamp 105 to hold the bearing bracket 108 in place. The servo motor 202 is started to rotate the grinding disc 205. The electric push rod 103 is started to push the fixed bracket 104 to move along the sliding groove 102, so that the outer surface of the bearing bracket 108 contacts the grinding disc 205. The grinding disc 205 grinds the area on the outer surface of the bearing bracket 108 that needs to be ground. The grinding position of the bearing bracket 108 is adjusted repeatedly to improve the grinding effect.

[0030] The second step: The worker can insert the grinding disc 205 into the fixed frame 203, align the connecting frame 204 with the fixed frame 203, insert the insertion rod 206 into the groove on the fixed frame 203 and the connecting frame 204, and use the nut 207 to lock the insertion rod 206, so that the fixed frame 203 and the connecting frame 204 can position the grinding disc 205. This makes it convenient for the worker to disassemble and replace the damaged grinding disc 205, ensuring the grinding effect of the device on the bearing bracket 108.
