[0002] A stone grinding machine is a device used to grind the surface of stone to achieve a flat, smooth, or specific shape and effect. It is widely used in the stone processing industry, such as architectural decoration, tombstone making, and stone carving art.

[0003] In existing grinding machines, the contact between the polishing wheel and the stone is often controlled by cylinders or lead screws. However, during the polishing process, a shallow layer of stone is ground off the stone surface, making it difficult for the polishing wheel to compensate for the height of the stone surface, thus affecting the polishing efficiency. Secondly, for stones with curved or uneven surfaces, traditional grinding and polishing methods are also difficult to adapt to the curvature of the curved surface, which can easily lead to incomplete grinding.

[0004] Therefore, an automatic grinding machine with high grinding accuracy is designed to overcome the above-mentioned technical defects. Utility Model Content

Detailed Implementation

[0024] This specific embodiment is an automatic grinding machine with high grinding precision, and its structural schematic diagram is as follows: Figures 1-6 As shown, the device includes a support cylinder 1, within which a movable rod 2 is slidably connected. The bottom end of the movable rod 2 penetrates the support cylinder 1. A first spring 3 is fitted inside the support cylinder 1 along the side wall of the movable rod 2. A grinding disc 5 is mounted at the bottom end of the movable rod 2. Several elastic grinding components are arranged on the bottom surface of the grinding disc 5 in a circular array around the central axis of the grinding disc 5. A water inlet component is located near the bottom end of the side wall of the movable rod 2.

[0025] Specifically, the movable rod 2 and the hollow rod 7 are respectively fixedly connected to the side walls of the slider. The inner wall of the support cylinder 1 and the side wall of the positioning groove 6 are respectively provided with sliding grooves that are adapted to the sliders. The sliders are slidably connected to the sliding grooves for limiting the movement, so that the movable rod 2 and the hollow rod 7 can only be raised and lowered and rotated as a whole, and cannot be rotated independently, so as to drive multiple polishing wheels 9 to perform rotary grinding and polishing.

[0026] like Figure 1 As shown, a mounting plate 4 is fixedly connected to the bottom end of the movable rod 2, and the grinding disc 5 is connected to the mounting plate 4 by bolts. This mounting and bolt connection method allows for the replacement of different models of the grinding disc 5 according to grinding requirements and stone specifications. Furthermore, the bolt connection offers advantages such as simple structure and high stability.

[0027] like Figure 2 and Figure 5 As shown, a hexagonal rod 16 is fixedly connected to the center of the top surface of the grinding disc 5. The hexagonal rod 16 has a hollow structure, and a hexagonal groove 17 is provided on the bottom surface of the mounting plate 4. The hexagonal rod 16 is adapted to the hexagonal groove 17. With this docking method, when replacing the grinding disc 5 with other specifications, the hexagonal rod 16 can serve as a positioning tool and also facilitate the connection between the water inlet 15 and the water storage chamber 12, thus facilitating water flow.

[0028] like Figure 3 and Figure 6 As shown, the elastic polishing assembly includes several positioning grooves 6 formed on the bottom surface of the polishing disc 5. A water storage cavity 12 is formed inside the polishing disc 5. The positioning grooves 6 are connected to the water storage cavity 12. A hollow rod 7 is movably connected inside the positioning groove 6. A second spring 11 is sleeved on the side wall of the hollow rod 7. The hollow rod 7 passes through the polishing disc 5 and is fixedly connected to a hollow plate 8. A polishing wheel 9 is assembled on the bottom surface of the hollow plate 8.

[0029] The first spring 3 is used to provide significant height compensation for the polishing wheel 9, which is suitable for stone surfaces with large height differences. The second spring 11 is used to provide minor height compensation for the polishing wheel 9, thereby effectively improving its grinding efficiency.

[0030] During the polishing process, if the polishing wheel 9 encounters a curved surface on the stone surface, the second spring 11 can be used to move the polishing wheel 9 downwards so that it contacts the curved surface. Furthermore, by setting up several polishing wheels 9, a single polishing wheel 9 can be raised and lowered to achieve efficient grinding.

[0031] like Figure 2 and Figure 5 As shown, the water inlet assembly includes a cylinder 13 rotatably connected to the side wall of the movable rod 2 near the bottom end. A connector 14 is fixedly connected to the side wall of the cylinder 13. A water inlet hole 15 is opened on the side wall of the movable rod 2 at the inner side of the cylinder 13. Corresponding water outlet holes 10 are opened on the bottom surface of the hollow plate 8 and the bottom surface of the polishing wheel 9.

[0032] Specifically, two annular sliders are fixedly connected to the inner wall of the cylinder 13, and two annular grooves are opened on the side wall of the movable rod 2. The water inlet 15 is located between the annular sliders. When the movable rod 2 rotates, the cylinder 13 will not rotate due to the rotational connection between the cylinder 13 and the movable rod 2, thus avoiding the phenomenon of water pipe entanglement.

[0033] Working principle: First, the support cylinder 1 is installed on a dual-axis or tri-axis grinding machine. The motor drives the support cylinder 1 and the grinding disc 5 to rotate. When the stone is transported to the bottom of the grinding disc 5, the lead screw or cylinder drives the support cylinder 1 to descend to a suitable height, so that the polishing wheel 9 is in close contact with the stone surface. At the same time, the first spring 3 and the second spring 11 are compressed. During the grinding process, the first spring 3 is used to perform a height compensation for the polishing wheel 9 once, and the second spring 11 is used to perform a second height compensation for the polishing wheel 9, so that the polishing wheel 9 can always be in contact with the stone surface during the grinding process, achieving the purpose of efficient grinding.

[0034] During the grinding process, the grinding effect can be enhanced by connecting the external pipe to the connector 14 and injecting water. The water flows into the water storage chamber 12 through the water inlet 15, and then into the hollow rod 7 and sprays out from the water outlet 10, which facilitates the removal of the stone powder and improves the smoothness of the stone surface.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
