[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0024] Example 1

[0025] Combination Figures 1-5A grinding device for the edges and corners of a building structure includes a base plate 1. A rotating column 2 is rotatably inserted through one side of the top of the base plate 1. A square column 3 is fixedly connected to the top of the rotating column 2. A first clamping plate 4 is fixedly connected to the top of the square column 3. Multi-stage cylinders 5 are fixedly connected to both sides of the top of the rotating column 2 corresponding to the square column 3. A square frame 6 is fixedly connected to the telescopic ends of the two multi-stage cylinders 5. The square frame 6 is set on the outer wall of the square column 3. Fixing blocks 7 are symmetrically fixedly connected to the four ends of the square frame 6. Rotating shafts 8 are rotatably inserted through the four sets of fixing blocks 7. Helical gears 9 are fixedly connected to both ends of the four rotating shafts 8. The helical gears 9 are meshed with each other. The outer walls of the four rotating shafts 8 are fixedly connected to the inner sides of the fixing blocks 7. The limiting plate 10 and the square frame 6 are fixedly connected to two side plates 11 at one end corresponding to the lower part of the rotating shaft 8. One side plate 11 is fixedly connected to a first motor 12 at one end. The driving end of the first motor 12 is fixedly connected to a drive shaft 13. The drive shaft 13 and the two side plates 11 are rotatably connected. The outer wall of the drive shaft 13 is fixedly connected to a first gear 14. The outer diameter of the first gear 14 is meshed with a second gear 15. The second gear 15 is fixedly connected to one of the rotating shafts 8. The top two sides of the bottom plate 1 are fixedly connected to upright plates 16. The top of the two upright plates 16 is fixedly connected to a top plate 17. A hydraulic rod 18 is fixedly passed through one side of the top of the top plate 17. The telescopic end of the hydraulic rod 18 is fixedly connected to a second clamping plate 19.

[0026] Specifically, firstly, the square wall panel is placed on the first clamping plate 4. The synchronous controller activates the multi-stage cylinder 5, pushing the square frame 6 upward along the square column 3 until it reaches the preset position. Then, the first motor 12 is activated, and the drive shaft 13 drives the first gear 14 to rotate, which in turn drives one of the rotating shafts 8 to rotate through the second gear 15. Due to the meshing of the helical gear 9, all rotating shafts 8 rotate synchronously, causing the limiting plate 10 to flip upward until it contacts the four sides of the square wall panel, ensuring that the wall panel is located in the exact center of the first clamping plate 4. The hydraulic rod 18 is activated, pushing the second clamping plate 19 downward to clamp the square wall panel together with the first clamping plate 4. The presence of the guide column ensures the stable movement of the second clamping plate 19 and avoids deflection. After the wall panel is firmly clamped, the limiting plate 10 returns to a vertical position, making room for subsequent grinding.

[0027] Example 2

[0028] See Figure 1 , Figure 2 and Figure 5Furthermore, based on Embodiment 1, L-shaped rods 20 are fixedly connected to all four sides of the top of the rotating column 2. A telescopic groove 21 is opened on one side of the top of the base plate 1 corresponding to the rotating column 2. An electric push rod 22 is fixedly connected to the bottom of the telescopic groove 21. A lifting plate 23 is fixedly connected to the telescopic end of the electric push rod 22. A baffle 24 is fixedly connected to the top of the lifting plate 23. The shapes of the lifting plate 23 and the telescopic groove 21 are compatible. A drive mechanism 25 is fixedly installed on one side of the bottom of the base plate 1. The drive mechanism 25 is connected to the rotating column 2. A fixed sleeve 26 is fixedly connected to the other side of the top of the base plate 1. A threaded rod 27 is rotatably connected to one side of the inner wall of the fixed sleeve 26. A mechanical arm 28 is threadedly connected to the outer wall of the threaded rod 27. A grinding mechanism 29 is installed on the other end of the mechanical arm 28. A second motor 30 is fixedly connected to one side of the outer wall of the fixed sleeve 26. The drive end of the second motor 30 is fixedly connected to the threaded rod 27.

[0029] Specifically, the second motor 30 starts, driving the threaded rod 27 to rotate. Through the threaded connection, the robotic arm 28 moves back and forth along the fixed sleeve 26. The other end of the robotic arm 28 is equipped with a grinding mechanism 29 to precisely grind the corners of the wall panel. When one side is finished grinding, the electric push rod 22 starts, pushing the lifting plate 23 and the baffle 24 to move downward, releasing the limit on the L-shaped rod 20. The drive mechanism 25 drives the rotating column 2 to rotate, so that the next corner to be ground is aligned with the grinding mechanism 29. The electric push rod 22 is started in the opposite direction, causing the baffle 24 to move upward until it contacts the next L-shaped rod 20. The rotating column 2 stops rotating, realizing precise switching of the corner to be ground.

[0030] In actual operation, the square wall panel is first placed on the first clamping plate 4. Then, the multi-stage cylinder 5 is controlled by the synchronous controller to move the square frame 6 upward to the appropriate position. After that, the first motor 12 is started to drive the drive shaft 13 to rotate, which in turn drives the first gear 14 and the second gear 15 to rotate, and drives one of the rotating shafts 8 to rotate. Due to the cooperation of the helical gear 9, the rotating shaft 8 can rotate synchronously, so the limiting plate 10 can be flipped upward synchronously and contact the four sides of the square wall panel. Therefore, the square wall panel can be placed in the center of the first clamping plate 4, avoiding back-and-forth adjustment, saving adjustment time and improving adjustment efficiency.

[0031] At this time, the hydraulic rod 18 is activated to move the second clamping plate 19 downward. At the same time, the presence of the guide column can prevent the second clamping plate 19 from deflecting. Therefore, the square wall panel can be clamped and fixed by the cooperation of the first clamping plate 4 and the second clamping plate 19. At this time, the limiting plate 10 is reset and in a vertical state to avoid affecting the subsequent grinding process. Then, the second motor 30 is activated to rotate the threaded rod 27. The thread effect of the threaded rod 27 can make the robotic arm 28 move back and forth, and the grinding mechanism 29 grinds the corners of the wall panel to improve the grinding efficiency.

[0032] After one side of the grinding is completed, the electric push rod 22 is activated to move the lifting plate 23 and the baffle 24 downwards, releasing the limiting operation on the L-shaped rod 20. At this time, the drive mechanism 25 drives the rotating column 2 to rotate. Then, the electric push rod 22 is activated in the opposite direction to move the baffle 24 upwards. When the next L-shaped rod 20 contacts the baffle 24, the rotating column 2 stops rotating. Therefore, the edge to be ground can be precisely switched to ensure the grinding effect.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
