[0019] like Figure 1 and Figure 2 As shown, a stone sculpture surface polishing device includes a support frame 1, which is arranged in a C shape, and also includes a polishing brush 2, an adjustment mechanism 3 and a positioning mechanism 4. The adjustment mechanism 3 is arranged on the side wall of the support frame 1 away from the opening. The polishing brush 2 is movably connected to the support frame 1 through the adjustment mechanism 3. The positioning mechanism 4 is arranged on the upper and lower side walls of the support frame 1 near the opening, and is used for carrying and clamping the stone sculpture. The adjustment mechanism 3 adjusts the polishing brush 2 to move left and right, so that the polishing brush 2 is close to or away from the stone sculpture.

[0020] like Figure 1 and Figure 2 As shown, in order to achieve the clamping of the stone sculpture, the positioning mechanism 4 includes a first cylinder 5, a second cylinder 6 and a driving assembly 7. The first cylinder 5 is fixedly connected to the inner bottom wall of the support frame 1 near the opening, and the telescopic end of the first cylinder 5 is fixedly connected to the bearing plate 8. The driving assembly 7 is provided on the bearing plate 8 and is used to drive the stone sculpture to rotate. The second cylinder 6 is fixedly connected to the upper wall of the support frame 1 near the opening, and the telescopic end of the second cylinder 6 is rotatably connected to the pressing plate 9. The first cylinder 5 and the second cylinder 6 are arranged opposite to each other, driving the first cylinder 5 to extend, pushing the bearing plate 8 to support the stone sculpture upward, and at the same time driving the second cylinder 6 to extend, pushing the pressing plate 9 to move downward, thereby achieving the clamping and positioning of the stone sculpture.

[0021] like Figure 1 and Figure 2 As shown, in order to realize the rotational polishing of the outer surface of the stone carving and rotate the clamped stone carving, the driving assembly 7 includes a rotating motor 10, a driving wheel 11 and a rotating disk 12. The rotating disk 12 is rotatably arranged on one side of the upper part of the supporting plate 8. The rotating motor 10 is fixedly installed on the bottom wall of the supporting plate 8 away from the rotating plate. The output end of the rotating motor 10 passes through the supporting plate 8 and is located on the upper part of the supporting plate 8. The driving wheel 11 is fixedly connected to the output end of the rotating motor 10. The driving wheel 11 is frictionally fitted with the side wall of the rotating disk 12. The rotating motor 10 drives the driving wheel 11 to rotate. The driving wheel 11 is frictionally contacted with the outer circumference of the rotating disk 12, driving the rotating disk 12 to rotate on the supporting plate 8, thereby realizing the rotation of the clamped stone carving.

[0022] like Figure 2 and Figure 3As shown, in order to realize the left and right movement adjustment of the grinding brush 2 in the support frame 1, the adjustment mechanism 3 includes a third cylinder 13, a positioning frame 14 and a connecting and positioning assembly 15. The third cylinder 13 is fixedly connected to the middle of the outer wall of the support frame 1 away from the opening side. The telescopic end of the third cylinder 13 passes through the support frame 1 and is slidably arranged inside the support frame 1. The positioning frame 14 is rotatably connected to the telescopic end of the third cylinder 13 through the connecting and positioning assembly 15, driving the third cylinder 13 to extend, so that the connecting and positioning assembly 15 and the grinding brush 2 move horizontally, so that the grinding brush 2 is close to the clamped stone sculpture.

[0023] like Figure 1 、 Figure 2 and Figure 4 As shown, in order to achieve the steering adjustment of the grinding brush 2 and act on different grinding surfaces of the stone carving, the connection positioning assembly 15 includes a connecting disk 16 and a positioning screw 17. The connecting disk 16 is fixedly connected to the telescopic end of the third cylinder 13. A screw hole 18 is opened on the outer circumferential side of the end face of the connecting disk 16. The screw holes 18 are arranged in a ring-shaped and evenly spaced arrangement with the central axis of the connecting disk 16 as the center. The positioning screws 17 pass through the positioning frame 14 and are threadedly connected to the screw holes 18 to fix the rotation angle of the positioning frame 14. The positioning frame 14 is rotatably connected to the connecting disk 16, so that the positioning frame 14 rotates with the central axis of the connecting disk 16 as the center, and the positioning screws 17 connected by bolts are inserted into the screw holes 18 to achieve the rotational positioning of the positioning frame 14.

[0024] In order to drive the grinding brush 2 to rotate, the positioning frame 14 is set in a C shape. The positioning frame 14 is rotatably connected to the end of the rotating disk 12 away from the third cylinder 13. The grinding brush 2 can be rotatably connected between the opposite inner walls of the positioning frame 14. A rotating motor 2 19 is installed on one side of the positioning frame 14. The output end of the rotating motor 2 19 is fixedly connected to one end of the grinding brush 2. The grinding brush 2 is driven to rotate in the positioning frame 14 by the rotating motor 2 19.

[0025] When in use, in the initial state, the first cylinder 5, the second cylinder 6 and the third cylinder 13 are all in the retracted state. The divided stone is placed on the rotating disk 12, and the first cylinder 5 is driven to extend, pushing the supporting plate 8 upward to support the stone sculpture. At the same time, the second cylinder 6 is driven to extend, pushing the pressing plate 9 downward to achieve the clamping and positioning of the stone sculpture. The clamping height of the stone sculpture can be adjusted according to the extension and contraction lengths of the first cylinder 5 and the second cylinder 6.

[0026] During grinding, the rotary motor 10 drives the driving wheel 11 to rotate. The driving wheel 11 is in frictional contact with the outer circumference of the rotating disk 12, driving the rotating disk 12 to rotate on the carrying plate 8, thereby rotating the clamped stone sculpture. At the same time, the rotary motor 2 19 is driven to rotate, causing the grinding brush 2 to rotate in the positioning frame 14.

[0027] Drive the third cylinder 13 to extend, push the positioning frame 14 toward the side of the rotating stone sculpture, and the polishing brush 2 acts on the side wall of the stone sculpture to polish;

[0028] When it is necessary to grind different planes of the stone carving, the positioning screw 17 is rotated to separate the positioning frame 14 from the connecting disk 16, and the positioning frame 14 is rotated so that it rotates around the central axis of the connecting disk 16. When the positioning frame 14 is tilted at a certain angle or placed horizontally, the positioning screw 17 connected by the bolt is inserted into the corresponding screw hole 18 to realize the rotational positioning of the positioning frame 14. The grinding brush 2 is then moved left and right by the third cylinder 13 for adjustment, which can be used for grinding different planes of the stone carving.
