The positioning clamp moves the plate to the middle position and fits against the two sides of the plate to position the plate. This achieves the goal of quickly positioning the plate before grinding. Attached Figure Description

[0025] Example: Please refer to Figure 1-4 A plate surface grinding device includes a base frame 1, with upright plates 2 fixedly connected to both sides of the top of the base frame 1. The center line of the base frame 1 and the center line of the upright plates 2 are on the same vertical plane. Connecting plates 4 are fixedly connected to both ends of the top of one side of the upright plates 2. A driving structure for driving the grinding structure to move is provided at the top of the base frame 1.

[0026] The drive structure includes a moving stage 6, one end of the connecting plate 4 is movably connected to the moving stage 6, one end of the top side of the upright plate 2 is fixedly connected to a fixed sleeve 3, the inside of the fixed sleeve 3 is movably connected to a threaded rod 5, one end of the moving stage 6 is provided with a threaded through hole 23, the other end of the top side of the upright plate 2 is fixedly connected to a rotating block 25, the other end of the moving stage 6 is provided with a through groove 24, and one end of the top side of the other side of the upright plate 2 is fixedly connected to a first servo motor 9.

[0027] The through groove 24 is slidably connected to the rotating block 25, and the threaded rod 5 is movably connected to the threaded through hole 23;

[0028] The output end of the first servo motor 9 extends into the interior of the fixed sleeve 3 and is fixedly connected to the threaded rod 5. The center line of the moving table 6 and the center line of the bottom frame 1 are on the same vertical plane.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, when the grinding structure at the bottom is activated during grinding, the first servo motor 9 is started to drive the threaded rod 5 to rotate. While the threaded rod 5 is rotating, it drives the moving table 6 to move to one side through the threaded through hole 23. The moving table 6 drives the grinding structure at the bottom to move, which can grind the surface of the board as a whole. At the same time, the rotating block 25 on one side of the upright plate 2 fits into the inside of the through groove 24, which can limit the moving table 6 to ensure the stability of the grinding structure when it moves. This realizes that the grinding structure can be automatically driven to move and grind the surface of the board as a whole.

[0030] A cylinder 7 is fixedly connected to the top of the moving stage 6. A piston rod 8 is fixedly connected to the output end of the cylinder 7. A connecting cover 17 is fixedly connected through the moving stage 6. Fixed plates 21 are fixedly connected to both ends of the bottom of the connecting cover 17. A rotating shaft 16 is movably connected to one end of the fixed plate 21. A grinding roller 15 is fixedly connected to the outside of the rotating shaft 16. A drive motor 20 is fixedly connected to one end of the fixed plate 21. Limiting strips 22 are fixedly connected to both ends of both sides of the connecting cover 17.

[0031] The limiting strip 22 is slidably connected to the limiting plate 14, and the limiting plate 14 is slidably connected to the connecting cover 17;

[0032] The output end of the drive motor 20 passes through the fixed plate 21 and is fixedly connected to the rotating shaft 16. The center line of the grinding roller 15 and the center line of the rotating shaft 16 are on the same horizontal plane.

[0033] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, before grinding, the cylinder 7 is started to push the connecting cover 17 down through the piston rod 8. The connecting cover 17 drives the grinding roller 15 down through the fixing plate 21. The limiting plate 14 at the bottom of the moving table 6 fits against both sides of the connecting cover 17 to limit the grinding roller 15, ensuring the stability during lifting and grinding. After the grinding roller 15 fits against the top of the board, the drive motor 20 is started to drive the grinding roller 15 to rotate through the rotating shaft 16 to grind the board. This allows the height of the grinding structure to be adjusted according to the thickness of the board.

[0034] Positioning sleeves 11 are fixedly connected to both sides inside the bottom frame 1. A two-way lead screw 13 is movably connected inside the positioning sleeve 11. Threaded sleeves 18 are movably connected to both sides outside the two-way lead screw 13. A movable plate 12 is fixedly connected to one side of the threaded sleeve 18. A positioning clamping plate 19 is fixedly connected to the top of the movable plate 12. A second servo motor 10 is fixedly connected to one side of the bottom frame 1.

[0035] The output end of the second servo motor 10 extends into the interior of the positioning sleeve 11 and is fixedly connected to the bidirectional lead screw 13. The threaded sleeves 18 on both sides of the bidirectional lead screw 13 are arranged symmetrically.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, before grinding the board, the board is placed on the top of the bottom frame 1. The second servo motor 10 is started to drive the bidirectional lead screw 13 to rotate. While the bidirectional lead screw 13 rotates, it drives the movable plates 12 on both sides to move towards the middle through the threaded sleeve 18. The movable plates 12 then drive the positioning clamp 19 to move. The positioning clamp 19 moves the board to the middle position and fits against the two sides of the board to position the board, thus realizing the quick positioning of the board before grinding.

[0037] Working Principle: In use, the sheet material is placed on the top of the base frame 1. The second servo motor 10 is started to drive the bidirectional lead screw 13 to rotate. As the bidirectional lead screw 13 rotates, it drives the movable plates 12 on both sides to move towards the center through the threaded sleeve 18. The movable plates 12 then drive the positioning clamp 19 to move. The positioning clamp 19 moves the sheet material to the center position and fits against both sides of the sheet material to position it. Then, the cylinder 7 is started to push the connecting cover 17 down through the piston rod 8. The connecting cover 17 drives the grinding roller 15 down through the fixed plate 21. The limiting plate 14 at the bottom of the moving table 6 fits against both sides of the connecting cover 17 to perform grinding. The roller 15 is limited to ensure stability during lifting and grinding. After the grinding roller 15 is attached to the top of the board, the drive motor 20 is started to drive the grinding roller 15 to rotate through the rotating shaft 16 to grind the board. During grinding, after the bottom grinding structure is started, the first servo motor 9 is started to drive the threaded rod 5 to rotate. While the threaded rod 5 is rotating, it drives the moving table 6 to move to one side through the threaded through hole 23. The moving table 6 drives the bottom grinding structure to move so that the surface of the board can be ground as a whole. At the same time, the rotating block 25 on one side of the upright plate 2 is attached to the inside of the through groove 24 to limit the moving table 6 to ensure the stability of the grinding structure during movement.
