[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-6 A grinding device for processing bent metal plates includes a base plate 1 and an arc-shaped plate 2. A U-shaped plate 3 is fixedly connected to the upper end of the base plate 1. Sliding sleeves 4 are fixedly connected between the inner walls of both sides of the U-shaped plate 3. Each sliding sleeve 4 has a slidable sliding rod 5. The opposite ends of the two sliding rods 5 are elastically connected to the inner wall of the corresponding sliding sleeve 4 through a first spring 6. Fixed plates 7 are fixedly connected to the opposite ends of the two sliding rods 5. Grinding strips 8 are fixedly connected to the opposite sides of the two fixed plates 7. The arc-shaped plate 2 is positioned... Between the two grinding strips 8, under the elastic action of the two first springs 6, the two grinding strips 8 can closely adhere to the surface of the arc plate 2 for grinding work. The upper end of the base plate 1 is fixedly connected to the vertical plate 9, and a moving groove 10 is opened in the vertical plate 9. An electric push rod 11 is installed in the top of the moving groove 10. The telescopic end of the electric push rod 11 is fixedly connected to the moving plate 12. The moving plate 12 is slidably connected to the inner wall of the moving groove 10. A motor 13 is installed on the outer wall of the moving plate 12. The motor 13 is a servo motor.

[0024] The output shaft of motor 13 passes through the movable plate 12 and is fixedly connected to a rotating plate 14. Connecting plates 15 are provided on both sides of the rotating plate 14. Through the cooperation of the electric push rod 11 and the movable plate 12, the connecting plates 15 and the two rotating plates 14 can be moved up and down, facilitating the clamping and fixing of the arc-shaped plate 2 for grinding and the removal of the arc-shaped plate 2 after grinding. Mounting plates 16 are fixedly connected to one side of each of the two connecting plates 15. Both mounting plates 16 are fixedly connected to the rotating plate 14 by bolts 17. Each mounting plate 16 has multiple mounting holes 18 that mate with corresponding bolts 17. Moving the mounting plate 16 allows the bolts 17 to be fixedly connected to the rotating plate 14 through different mounting holes 18. This allows the position of the connecting plate 15 to be adjusted to accommodate arc plates 2 of different specifications. Each of the two connecting plates 15 has a sliding groove 19. Each of the two sliding grooves 19 is equipped with a clamping mechanism for holding the arc plate 2. Each clamping mechanism includes two sliding plates 20, and both sliding plates 20 are slidably connected to the inner wall of the corresponding sliding groove 19.

[0025] In this configuration, the lower ends of each pair of mating sliding plates 20 extend to the outside. A wedge block 21 is fixedly connected to the opposite side of each pair of mating sliding plates 20. The opposing sides of each pair of mating sliding plates 20 are elastically connected to the inner wall of the corresponding slide groove 19 via a second spring 22. A threaded rod 23 is rotatably connected to the inner top of each of the two slide grooves 19. Each threaded rod 23 engages with the corresponding wedge block 21. The lower ends of each threaded rod 23 are located directly above the inclined surfaces of the corresponding two wedge blocks 21, and the upper ends of each threaded rod 23 extend... Extending to the outside and fixedly connected to knobs 24, both knobs 24 have protective layers on their outer walls, both of which are made of rubber. The two ends of the arc plate 2 are clamped and fixed by the sliding plate 20, which can prevent the arc plate 2 from shaking or shifting during grinding, ensuring grinding accuracy and quality. The motor 13 causes the rotating plate 14 to rotate in both directions, so that the arc plate 2 can slide back and forth between the two grinding strips 8. In this way, the surface of the arc plate 2 is in full contact with the grinding strips 8, ensuring that the entire surface of the arc plate 2 is evenly stressed and improving grinding efficiency.

[0026] In this utility model, during use, the arc plate 2 is first moved to be positioned between the two grinding strips 8. The arc plate 2 will press the two fixed plates 7, causing the two sliding rods 5 to slide in the corresponding sliding sleeves 4 and press the corresponding first springs 6. Then, under the elastic action of the two first springs 6, the two grinding strips 8 will adhere to the surface of the arc plate 2. In this way, during subsequent grinding, as the arc plate 2 moves, the two grinding strips 8 can always adhere to the surface of the arc plate 2, thereby improving the grinding effect of the arc plate 2.

[0027] Then, the electric push rod 11 is activated, causing the moving plate 12 to move down along with the rotating plate 14. The two connecting plates 15 also move down. After moving to a suitable distance, the two knobs 24 can be rotated to move the two threaded rods 23 up to release the limit on the corresponding two wedge blocks 21. Under the elastic action of the two second springs 22, each pair of mating wedge blocks 21 will move relative to each other, which in turn causes each pair of mating sliding plates 20 to move relative to each other until the multiple sliding plates 20 clamp and fix the two ends of the arc plate 2. This can ensure the stability of grinding and prevent the arc plate 2 from shaking or shifting during grinding.

[0028] After clamping both ends of the arc plate 2, the motor 13 can be started. After the motor 13 starts, it rotates the rotating plate 14 in both directions, which causes multiple sliding plates 20 to slide back and forth between the two grinding strips 8 to grind the arc plate 2. In this way, the upper and lower surfaces of the arc plate 2 have a chance to fully contact the grinding strips 8, ensuring that the entire surface of the arc plate 2 is evenly stressed, avoiding over- or under-grinding in some areas, and improving grinding efficiency. After grinding, the two knobs 24 can be reversed to move each pair of sliding plates 20 in opposite directions, releasing the clamping and fixing of both ends of the arc plate 2. Then, the rotating plate 14 and the connecting plate 15 are moved back to their original positions, and the ground arc plate 2 can be taken out.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
