Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-4As shown, a plate grinding device includes a base 1, a control panel 2 mounted on the base 1, a support frame 3 mounted on the base 1, a guide plate 4 slidably mounted on the support frame 3, a moving block 5 slidably mounted on the guide plate 4, a hydraulic cylinder 6 mounted on the moving block 5, a hydraulic rod 7 mounted on the hydraulic cylinder 6, a connecting rod 8 fixedly mounted on the bottom side of the hydraulic rod 7, a ball 9 mounted on the bottom side of the connecting rod 8, a limit rod 30 fixedly mounted on the ball 9, a ball seat 10 sleeved around the ball 9, a fixing frame 11 mounted on the bottom side of the ball seat 10, a drive motor 12 mounted on the fixing frame 11, a connecting plate 13 mounted on the output shaft of the drive motor 12, a grinding disc 14 mounted on the bottom side of the connecting plate 13, and a first guide groove 15 formed on the support frame 3. A first stepper motor 16 is mounted on the wall via a base. A first lead screw 17 is mounted on the output shaft of the first stepper motor 16. The first lead screw 17 is rotatably mounted on the inner wall of the first guide groove 15. A first guide block 18 is assembled inside the first guide groove 15 and is fixedly connected to the side wall of the guide plate 4. A second guide groove 19 is formed inside the guide plate 4. A second stepper motor 20 is mounted on the outer wall of the guide plate 4 via a base. A second lead screw 21 is mounted on the output shaft of the second stepper motor 20 and is rotatably mounted on the inner wall of the second guide groove 19. A second guide block 22 is assembled inside the second guide groove 19 and is fixedly connected to the moving block 5. During operation, the existing grinding device grinds the plate material... During the process, it is impossible to accurately grind the board according to the surface curvature, resulting in poor grinding effect. After clamping and fixing the brake plate 29 by clamping block 28, the hydraulic cylinder 6 is operated by control panel 2. The hydraulic rod 7 drives the grinding disc 14 to move vertically downward, so that the grinding disc 14 contacts the surface of the brake plate 29. At the same time, drive motor 12 operates, driving the grinding disc 14 to rotate at high speed, so that the grinding disc 14 grinds the brake plate 29. During this process, the second stepper motor 20 operates, driving the second lead screw 21 to rotate. The second lead screw 21 drives the second guide block 22 on it to move horizontally left and right. The second guide block 22 drives the moving block 5 to move horizontally left and right. The moving block 5 drives the grinding disc 14 on it to move horizontally left and right. After that, through The first step motor 16 operates, driving the first lead screw 17 to rotate. The first lead screw 17 drives the first guide block 18 on it to move horizontally back and forth. The first guide block 18 drives the guide plate 4 to move horizontally back and forth. The guide plate 4 drives the grinding disc 14 to move horizontally back and forth, thus achieving full grinding of the brake plate 29. During this process, the brake plate 29 avoids being an arc structure. It can rotate back and forth around the limit rod 30 within the ball seat 10 through the ball 9. This allows the ball seat 10, the fixing frame 11, the drive motor 12, the connecting plate 13, and the grinding disc 14 to rotate flexibly back and forth relative to the hydraulic rod 7. That is, the grinding disc 14 can always be in contact with the arc surface of the brake plate 29, achieving full grinding of the brake plate 29 and improving the grinding effect.

[0020] Please see Figure 5 As shown, a placement platform 23 is installed on the base 1. A sliding groove 24 is opened in the placement platform 23. A third lead screw 25 is rotatably installed on the inner wall of the sliding groove 24. The threads on the third lead screw 25 are symmetrical and opposite. One end of the third lead screw 25 passes through the side wall of the placement platform 23 and is equipped with a knob 26. Two sets of sliders 27 are symmetrically assembled in the sliding groove 24. Clamping blocks 28 are installed on the sliders 27, and a brake plate 29 is placed on the clamping blocks 28. During operation, the existing grinding device has difficulty in stably clamping the plate during the grinding process, resulting in poor plate stability. By rotating the knob 26, the third lead screw 25 is driven to rotate. The third lead screw 25 drives the two sets of sliders 27 to move synchronously relative to each other. The two sets of sliders 27 drive the two sets of clamping blocks 28 to move synchronously relative to each other. The two sets of clamping blocks 28 clamp and fix the brake plate 29, and the clamping blocks 28 support the bottom side of the brake plate 29, realizing stable clamping of the brake plate 29 and improving the stability of the plate.

[0021] Working principle: Existing grinding devices struggle to stably clamp the sheet metal during grinding, resulting in poor sheet metal stability. Rotating knob 26 drives the third lead screw 25, which in turn moves two sets of sliders 27 synchronously relative to each other. These sliders, in turn, move two sets of clamping blocks 28 synchronously relative to each other, clamping and fixing the brake plate 29 and supporting its underside. This stable clamping improves sheet metal stability. Furthermore, existing grinding devices cannot precisely grind the sheet metal according to its surface curvature, leading to poor grinding results. After clamping and fixing the brake plate 29 with the clamping blocks 28, the control panel 2 controls the hydraulic cylinder 6. The hydraulic rod 7 moves the grinding disc 14 vertically downwards, bringing it into contact with the surface of the brake plate 29. Simultaneously, the drive motor 12 operates, driving the grinding disc 14 to rotate at high speed, thus grinding the brake plate 29. During the process, the second stepper motor 20 operates, driving the second lead screw 21 to rotate. The second lead screw 21 drives the second guide block 22 on it to move horizontally left and right. The second guide block 22 drives the moving block 5 to move horizontally left and right. The moving block 5 drives the grinding disc 14 on it to move horizontally left and right. Then, the first stepper motor 16 operates, driving the first lead screw 17 to rotate. The first lead screw 17 drives the first guide block 18 on it to move horizontally back and forth. The first guide block 18 drives the guide plate 4 to move horizontally back and forth. The guide plate 4 drives the grinding disc 14 to move horizontally back and forth, thus achieving comprehensive grinding of the brake plate 29. During this process, the brake plate 29 avoids being an arc structure. Through the ball 9, it can rotate back and forth around the limit rod 30 within the ball seat 10. This allows the ball seat 10, the fixing frame 11, the drive motor 12, the connecting plate 13, and the grinding disc 14 to rotate flexibly back and forth relative to the hydraulic rod 7. That is, the grinding disc 14 can always be in contact with the arc surface of the brake plate 29, achieving comprehensive grinding of the brake plate 29 and improving the grinding effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
