At the same time, the circular protective cover 304 can protect the internal components such as the motor box, preventing damage to them caused by debris generated during the grinding process.
[0027] A motor box is fixedly connected to the inner top wall of the circular protective cover 304. A servo motor 305 is fixedly connected inside the motor box. A transmission rod 306 is fixedly connected to the output end of the servo motor 305. A grinding disc 307 is fixedly connected to the bottom end of the transmission rod 306. The purpose of this design is that after the servo motor 305 is started, it can drive the transmission rod 306 to rotate at high speed, which in turn drives the grinding disc 307 to rotate. The rotating grinding disc 307 is used to grind the surface of the cylindrical roller bearing, ensuring the efficiency and stability of grinding.
[0028] The water spray assembly 5 includes a water storage box 501 fixedly connected to the top of the fixed plate 4. A water pump box 502 is fixedly connected to one side of the top of the water storage box 501. A connecting pump body 503 is fixedly connected inside the water pump box 502.

One end of the output pipe 505 is connected through to one side of the top of the circular protective cover 304. The purpose of this design is that when the connecting pump body 503 is working, water is drawn out of the water storage box 501 through the input pipe 504 and then transported to the circular protective cover 304 through the output pipe 505. Finally, it is sprayed on the grinding area to cool the rollers and the grinding disc 307, reduce the heat generated during the grinding process, prevent the rollers from being affected by overheating, and wash away the debris generated during grinding, thereby improving the grinding quality.
[0029] A water inlet pipe 506 is connected to the other side of the top of the water storage box 501. A protective cover 507 is threaded onto the surface of the water inlet pipe 506. The purpose of this design is that after the protective cover 507 is opened, water can be added to the water storage box 501 through the water inlet pipe 506 to ensure that the water spraying assembly 5 has enough water to work continuously. The protective cover 507 can prevent dust, debris and other objects from entering the water storage box 501, avoid clogging the input pipe 504 and the connecting pump body 503 and other components, and ensure the normal operation of the water spraying assembly 5.

The purpose of this design is that when the control disk 603 is rotated, the threaded rod 602 will rotate under the support of the bearing. Since the threads on both sides of the surface of the threaded rod 602 are in opposite directions, the clamping arc plates 604 on both sides will move towards or away from each other, thereby achieving stable clamping of cylindrical roller bearings of different sizes, ensuring that the rollers will not be displaced or shake during the grinding process, and ensuring grinding accuracy.

[0033] Second step: Start the hydraulic press body 303, adjust the height of the circular protective cover 304 according to the size of the roller, so that the grinding disc 307 is close to the surface of the roller, and then start the servo motor 305 to drive the transmission rod 306 and the grinding disc 307 to rotate at high speed to grind the roller.
[0034] Third step: During the grinding process, start the connecting pump body 503, draw water from the water storage box 501 through the input pipe 504, and deliver it to the circular protective cover 304 through the output pipe 505 to spray water to cool and clean the grinding area. After grinding is completed, turn off the servo motor 305, the connecting pump body 503 and the hydraulic press body 303, rotate the control disk 603 to loosen the clamping arc plate 604, and take out the ground roller.
