The output shaft end of the second motor 207 passes through the outer surface of the mounting seat 206 and extends to the other side. The output shaft end of the second motor 207 is provided with a diamond grinding wheel 208.

[0024] The effect achieved by the entire embodiment 1 is that the second motor 207 is started to drive the diamond grinding wheel 208 to rotate at a high speed, and then the first motor 203 is started to drive the first bidirectional screw 204 to rotate. When the first bidirectional screw 204 rotates, the two sliders 205 are close to each other, and the corresponding diamond grinding wheels 208 are in contact with the end surface of the bearing ring 5, so that the two end surfaces of the bearing ring 5 can be ground at the same time, which greatly improves the work efficiency.

[0025] Embodiment 2, as Figure 1-Figure 4As shown, the rotating mechanism 3 includes a mounting frame 301, which is fixedly mounted on the top of the base 1, and a third motor 302 is fixedly mounted on the front surface of the mounting frame 301. A rotating shaft 303 is fixedly mounted on the output end of the third motor 302. The outer surface of the rotating shaft 303 penetrates the front surface of the mounting frame 301 and extends to the inside. A rotating disk 304 is fixedly mounted on the outer surface of the rotating shaft 303. Multiple clamping mechanisms 4 all include second bidirectional screw rods 401. Multiple second bidirectional screw rods 401 are equidistantly distributed on the outside of the rotating disk 304. A supporting seat 402 is symmetrically rotated on the outer surface of the second bidirectional screw rod 401. The supporting seat 402 is fixedly mounted on the outer surface of the rotating disk 304. The second bidirectional screw rod 401 One end is fixedly connected to a rocking wheel 403, a positioning seat 404 is arranged between the two supporting seats 402, the positioning seat 404 is fixedly installed on the outer surface of the turntable 304, the left and right outer surfaces of the positioning seat 404 are symmetrically provided with limiting holes 405, the outer surface of the second bidirectional screw 401 is symmetrically threadedly connected with a movable plate 406, the outer surfaces of the opposite sides of the two movable plates 406 are symmetrically fixedly installed with limiting rods 407, the limiting rods 407 are slidably arranged inside the limiting holes 405, a clamping block 408 is fixedly installed on the top of the movable plate 406, the outer surfaces of the opposite sides of the two clamping blocks 408 are provided with anti-skid pads 409, and a bearing ring 5 is arranged between the outer surfaces of the two anti-skid pads 409.

[0026] The effect achieved by the entire embodiment 2 is that the bearing ring 5 is placed in the clamping mechanism 4 located on the top of the turntable 304, the bearing ring 5 is placed in the arc groove on the positioning seat 404, and the second bidirectional screw 401 is driven to rotate by rotating the rocker 403, so that the two movable plates 406 are close to each other, and the corresponding clamping blocks 408 are used to clamp and fix the bearing ring 5. The anti-slip pad 409 can be provided to increase the friction force on the bearing ring 5 to avoid shaking during the grinding process. When the movable plate 406 moves, The limit rod 407 slides in the limit hole 405, which guides and limits the movable plate 406, thereby improving stability. During the grinding process, the staff uses the time gap to clamp another bearing ring 5 to be ground on the idle clamping mechanism 4 on the top of the turntable 304. After the grinding of the bearing ring 5 below is completed, the turntable 304 is cyclically rotated to move it to the top again, then it is removed and the bearing ring 5 to be ground is clamped. This cycle is repeated, thereby achieving continuous grinding, reducing downtime and waiting time, and further improving work efficiency.

[0027] Working principle: When in use, the bearing ring 5 is placed in the clamping mechanism 4 located on the top of the turntable 304, and the bearing ring 5 is placed in the arc-shaped groove on the positioning seat 404. The second bidirectional screw 401 is driven to rotate by rotating the rocker 403, so that the two movable plates 406 are close to each other, and the corresponding clamping blocks 408 are used to clamp and fix the bearing ring 5. After that, the third motor 302 is started to drive the rotating shaft 303 to rotate. When the rotating shaft 303 rotates, it drives the turntable 304 to rotate synchronously. When the turntable 304 rotates, the bearing ring 5 in the clamping mechanism 4 is moved downward until it moves to the bottom position. At this time, the bearing ring 5 is located between the two diamond grinding wheels 208, and then the second motor 207 is started to drive the diamond grinding wheels 208 to move up. The first motor 203 is then started to drive the first bidirectional screw rod 204 to rotate. When the first bidirectional screw rod 204 rotates, the two sliders 205 are close to each other, and the corresponding diamond grinding wheel 208 contacts the end surface of the bearing ring 5, so that the two end surfaces of the bearing ring 5 can be ground at the same time, which greatly improves the work efficiency. At the same time, during the grinding process, the staff uses the time gap to clamp another bearing ring 5 to be ground on the idle clamping mechanism 4 on the top of the turntable 304. After the grinding of the bearing ring 5 below is completed, the turntable 304 is cyclically rotated to move it to the top again, and then it is removed and the bearing ring 5 to be ground is clamped. The cycle is repeated, so that continuous grinding can be achieved, the downtime waiting time is reduced, and the work efficiency is further improved.
