The turntable two 407 drives the sliding grooves one 404 to move away from each other by slidingly cooperating the sliding column one 409 with the sliding groove two 408 and the sliding plate 405 with the sliding groove one 404. The sliding grooves one 404 drive the sliding plate 405 to move synchronously, so that the sliding plate 405 fits against the inner wall of the top of the valve 3. The sliding plate 405 realizes the stable clamping of the valve 3 by cooperating with the supporting cone 105, which can meet the clamping requirements of valves of different models and improve the applicability of the device;

[0066] The motor four 418 drives the bevel gear one 417 to rotate. The bevel gear one 417 drives the connecting cylinder 403 to rotate correspondingly by meshing with the bevel gear ring 416. The connecting cylinder 403 drives the valve 3 to rotate synchronously by connecting with the turntable one 402 and the abutting plate 406 abutting against the inner wall of the valve 3, which can meet the grinding requirements in different directions on the surface of the valve 3;

[0067] The motor three 213 drives the grinding rod 216 to rotate, which can grind the outer wall of the valve 3. The electric moving platform 207 drives the grinding rod 216 to move synchronously by slidingly cooperating with the threaded plate 206, which can perform circumferential grinding on the valve 3. The motor two 212 drives the gear one 211 to rotate. The gear one 211 drives the rotating plate 214 to rotate by meshing with the gear two 215. The rotating plate 214 drives the motor three 213 and the grinding rod 216 to rotate synchronously, thereby adjusting the grinding angle of the grinding rod 216 to meet the grinding requirements at different angles. The electric telescopic rod one 209 drives the movable plate 210 to expand and contract by connecting with the movable plate 210 and the movable plate 210 slidingly cooperating with the vertical plate 208. The movable plate 210 drives the rotating plate 214 to move synchronously to adjust the position of the grinding rod 216, so as to meet the comprehensive grinding treatment of the valve 3 and improve the practicability of the device;

[0068] After the surface grinding operation of the valve 3 is completed, reset the grinding assembly 2. At the same time, the motor five 502 drives the bevel gear three 511 to rotate reversely. The bevel gear three 511 drives the screw two 503 to rotate by meshing with the bevel gear two 501. The screw two 503 drives the threaded barrel 506 to move upward first and then rotate horizontally along the track of the guide groove 5041 through the threaded connection with the threaded barrel 506 and the sliding fit between the slider 5061 and the guide groove 5041. The threaded barrel 506 drives the lifting cylinder 507 to move synchronously through the cooperation between the positioning block 5062 and the positioning groove 5071. The lifting cylinder 507 drives the mounting plate 401 to move upward first and then rotate horizontally through the connection of the bracket 508, the connecting column 509 and the connecting plate 510, so that the mounting plate 401 is disengaged from the contact with the valve 3 and moves away from the housing 101, facilitating the quick removal of the ground valve 3 and the convenient placement of the valve 3 to be ground.

[0069] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
