The grinding assembly 1 is composed of a fixing frame and a grinding machine. A lead screw is rotatably arranged on the fixing frame, and the grinding machine is threadedly connected to the lead screw on the fixing frame. Four fixing seats are connected to the bottom of the grinding assembly 1. The grinding machine of the grinding assembly 1 is adapted to the inner wall of the valve. The rotating motor 102 is detachably installed on the fixing frame. The output shaft of the rotating motor 102 is connected to the first gear 103 through a coupling. The slide rails 2 are symmetrically connected to the front and back of the fixing frame. A moving plate 3 is slidably arranged between the two slide rails 2. The sliding direction of the moving plate 3 is left and right sliding. The left and right sliding of the moving plate 3 is used to quickly replace the next valve to be ground, improving the grinding efficiency. Limiting plates 4 are symmetrically welded to the front and back of the left and right sides of the moving plate 3. Placement disks 5 are rotatably arranged symmetrically on the left and right of the moving plate 3. Four cutouts are provided on the outer wall of the upper part of the placement disk 5. A turntable 7 is rotatably arranged in the middle of the placement disk 5. Four inclined holes are provided on the turntable 7. Clamping blocks 6 are slidably arranged in the four inclined holes. The clamping blocks 6 are located in the corresponding cutouts on the placement disk 5. The inward movement of the clamping blocks 6 can clamp and fix the valve. A torsion spring 8 is connected between the bottom of the turntable 7 and the adjacent placement disk 5. A second gear 9 is connected to the bottom of the placement disk 5. The second gear 9 on the left meshes with the first gear 103. A mounting bracket 10 is welded to the front of the front slide rail 2. Fixing rings 11 are symmetrically welded to the front of the top of the moving plate 3. A fixing rod 12 is slidably arranged on the mounting bracket 10. A pull ring is welded to the front of the fixing rod 12. The fixing rod 12 is used to fix the moving plate to prevent it from shifting. The fixing rod 12 catches the fixing ring 11 on the left. An elastic member 13 is connected between the mounting bracket 10 and the fixing rod 12. A fixing block 14 is connected to the placement disk 5. A screw rod 15 is threadedly arranged on the fixing block 14. The screw rod 15 fastens the adjacent turntable 7.

[0028] When it is necessary to use this device to grind the inner wall of the valve, first place the device at the designated position, and then rotate the screw rod 15. The rotation of the screw rod 15 will move upward to loosen the turntable 7. Then, rotate the left placing plate 5. The rotation of the left placing plate 5 will squeeze the left clamping block 6 to move along the inclined hole and expand. The left torsion spring 8 will deform. Subsequently, the valve can be placed on the left placing plate 5. Then, loosen the left placing plate 5. The left torsion spring 8 will return to its original state, driving the left placing plate 5 to reverse. The reverse rotation of the left placing plate 5 drives the left clamping block 6 to move back along the inclined hole to clamp the valve. Then, reverse the screw rod 15 to make it move downward to fix the left turntable 7 and placing plate 5 again. Then, start the rotary motor 102. The rotation of the output shaft of the rotary motor 102 drives the left first gear 103 to rotate. The rotation of the left first gear 103 drives the left second gear 9 to rotate. The rotation of the left second gear 9 drives the left placing plate 5 to rotate. The rotation of the left placing plate 5 can drive the valve to rotate. At the same time, the grinding machine in the grinding assembly 1 can be controlled to move downward into the valve and the grinding machine can be started. Then, the inner wall of the valve can be ground by the rotation of the grinding machine. During the grinding interval, people can repeat the above operations to place the next valve to be ground on the right placing plate 5. After the left valve is ground, turn off the rotary motor 102 and the grinding machine, and control the grinding machine to move upward to reset. Then, pull the fixing rod 12 forward to loosen the left fixing ring 11. The elastic member 13 is compressed. Then, pull the moving plate 3 to the left. The slide rail 2 plays a guiding role, so that the right limiting plate 4 blocks on the right side of the slide rail 2 for limiting. After the valve is placed on the right side, it is located directly below the grinding machine. Then, loosen the fixing rod 12. The elastic member 13 returns to its original state, driving the fixing rod 12 to move backward to lock the right fixing ring 11. And the first gear 103 will mesh with the right second gear 9. Then, the rotary motor 102 can be started again to drive the valve to rotate, and the inner wall of the right valve can be ground by controlling the grinding machine on the grinding assembly 1 to move downward. During the grinding process of the right valve, the left turntable 7 can be rotated to remove the ground valve, and the valve to be ground subsequently can be placed on the left placing plate 5. In this way, the valves can be ground back and forth in turn to improve the grinding efficiency. When this device is not needed, turn off the grinding machine and the rotary motor 102 on the grinding assembly 1.
