The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] Please refer to Figure 1 , Figure 2 and Figure 4A polishing and grinding mechanism includes a fixed frame 1, which is welded. The lower end of the fixed frame 1 can be connected to a fixed universal wheel to facilitate the device to move back and forth. At the same time, when the material is large and inconvenient to move, the fixed frame 1 can be moved to make the device polish and grind the material. A crossbeam 11 is symmetrically fixed on the upper end of the fixed frame 1. A walking trolley 12 is moved on the upper end of the crossbeam 11. The crossbeam 11 is connected to the fixed frame 1 by welding or a detachable fixing method. The walking trolley 12 is an existing structure and is used to walk on the crossbeam 11. No more details are given here. The walking wheel of the walking trolley 12 adopts a single-sided wheel to prevent the walking trolley 12 from walking on the crossbeam 11. The derailment phenomenon is prevented. A sleeve 13 is symmetrically fixed to the lower end of the traveling trolley 12. A sliding shaft 14 is connected to each of the sleeves 13. A fixed plate 2 is fixed to the lower end of the sliding shaft 14. The sleeve 13 is slidably connected to the sliding shaft 14. The height of the grinding disc 3 is controlled by controlling the length of the sliding shaft 14 sliding out of the sleeve 13, so that the device can grind materials of different heights, and has stronger applicability. A vertical cycloid reducer 21 is fixed to the upper end of the fixed plate 2. A three-phase asynchronous motor 22 is arranged at the upper end of the vertical cycloid reducer 21. The vertical cycloid reducer 21 reduces the output speed of the three-phase asynchronous motor 22. Since the grinding disc 3 itself has a large reduction ratio and a high transmission The advantages of high efficiency, small size, light weight, few failures, long life, stable and reliable operation, low noise, convenient disassembly and assembly, easy maintenance, simple structure, strong overload capacity, impact resistance, and small inertia moment make the device more efficient, stable, durable and easy to maintain during the grinding process. The lower end of the fixed plate 2 is provided with a plurality of angle adjustment components 6 along its circumference, and the lower end of the angle adjustment component 6 is connected with an angle adjustment disk 5, and the lower end of the angle adjustment disk 5 is provided with a grinding disk 3. The fixed plate 2 and the angle adjustment disk 5 are connected by the angle adjustment component 6, and the grinding disk 3 is rotatably connected to the angle adjustment disk 5. By adjusting the length of the angle adjustment components 6 at different positions, the inclination angle of the angle adjustment disk 5 is adjusted, thereby achieving In order to adjust the angle of the grinding disc 3 to adapt to the grinding of materials with different inclination angles, the lower end of the vertical cycloid pin reducer 21 is connected with a universal joint 4, and the lower end of the universal joint 4 is connected to the grinding disc 3. The vertical cycloid pin reducer 21 is fixedly connected to the three-phase asynchronous motor 22, and the input end of the vertical cycloid pin reducer 21 is connected to the output end of the three-phase asynchronous motor 22. The output end of the vertical cycloid pin reducer 21 is connected to the universal joint 4. The output end of the vertical cycloid pin reducer 21 is connected to the connecting rod 33 of the grinding disc 3 through the universal joint 4. When the inclination angle of the grinding disc 3 is adjusted, it does not affect the vertical cycloid pin reducer 21 driving the grinding disc 3 to rotate through the universal joint 4.

[0023] See also Figure 2 , Figure 3and Figure 4 The angle adjustment assembly 6 includes an adjustment cylinder 61. A threaded rod 62 is threadedly connected to the upper end of the adjustment cylinder 61. The upper end of the threaded rod 62 is rotatably connected to the fixed plate 2. The lower end of the adjustment cylinder 61 is rotatably connected to a sphere 63. A plurality of hinge seats 51 are fixed along the circumference of the upper end of the angle adjustment disc 5. The spheres 63 correspond to the hinge seats 51 one by one. The adjustment cylinder 61 is threadedly connected to the threaded rod 62.

Anti-slip lines are provided on the outer wall of the adjustment cylinder 61. By providing anti-slip lines on the outer wall of the adjustment cylinder 61, the phenomenon of slipping is prevented when holding the adjustment cylinder 61 and rotating it. An even number of through holes 64 are provided along the circumference of the outer wall of the adjustment cylinder 61. At the same time, by providing through holes 64 on the outer wall of the adjustment cylinder 61, it is convenient to clean the inside of the adjustment cylinder 61, ensuring the smooth meshing of the adjustment cylinder 61 and the threaded rod 62. At the same time, a rod is inserted into the through hole 64, and the adjustment cylinder 61 is rotated by pushing the rod, achieving the effect of labor saving and facilitating the adjustment of the meshing length between the threaded rod 62 and the adjustment cylinder 61. The angle adjustment assembly 6 can be replaced by a telescopic rod that can automatically extend and retract, thereby realizing the automatic adjustment of the inclination angle of the grinding disc 3.

[0024] Please refer to Figure 2 and Figure 4 A plurality of reinforcing plates 31 are fixed along the circumference of the upper end of the grinding disc 3. The reinforcing plates 31 are used to increase the overall strength of the grinding disc 3 and prevent the grinding disc 3 from deforming when grinding materials. A connecting rod 33 is fixed to the upper end of the grinding disc 3. A connecting cylinder 32 is fixed to the outside of the connecting rod 33. The connecting rod 33 is connected to the output end of the vertical cycloidal pin reducer 21 through a universal joint 4, realizing the transmission relationship, facilitating the vertical cycloidal pin reducer 21 to drive the grinding disc 3 to rotate, and realizing the grinding of materials. The connecting cylinder 32 is rotatably connected to the angle adjustment disc 5, so that the grinding disc 3 can still rotate and grind after tilting. The height of the connecting rod 33 is greater than the height of the connecting cylinder 32. The height of the connecting rod 33 is set to be greater than the height of the connecting cylinder 32, facilitating the connection of the grinding disc 3 with the angle adjustment disc 5 and the vertical cycloidal pin reducer 21. The connecting rod 33 is connected to the universal joint 4, and the connecting cylinder 32 is rotatably connected to the angle adjustment disc 5. The grinding disc 3, the reinforcing plates 31, the connecting cylinder 32, and the connecting rod 33 are integrally formed by a casting process, ensuring the firm connection between the grinding disc 3 and the reinforcing plates 31, the connecting cylinder 32, and the connecting rod 33, and at the same time increasing the overall strength of the grinding disc 3.

[0025] When the present utility model is in use:

[0026] First, the traveling trolley 12 moves on the crossbeam 11, and the traveling trolley 12 moves the grinding disc 3 above the material to be ground;

[0027] Then, the inclination angle of the grinding disc 3 is adjusted according to the surface of the material to be ground. When the material to be ground is a flat surface, the lengths of the multiple angle adjustment components 6 are the same; when the surface to be ground is an inclined surface, by adjusting the lengths of the angle adjustment components 6, the lengths of the multiple angle adjustment components 6 are different, resulting in different inclination angles of the grinding disc 3. The grinding disc 3 can be made to fit the inclined surface by adjusting the angle adjustment components 6;

[0028] Next, the extension amount of the sliding shaft 14 from the sleeve 13 is adjusted according to the thickness to be ground. During the grinding process, the sliding shaft 14 slowly extends from the sleeve 13 until the sliding shaft 14 stops extending when the extension amount of the sliding shaft 14 is the same as the grinding thickness;

[0029] Finally, during the grinding process, the three-phase asynchronous motor 22 operates to drive the vertical cycloidal pin reducer 21 to rotate. The vertical cycloidal pin reducer 21 decelerates the rotational speed of the three-phase asynchronous motor 22 and transmits it to the grinding disc 3 through the universal joint 4, so that the grinding disc 3 grinds the material.
