[0001] The utility model relates to the technical field of rock slab grinding and fixing, in particular to a rock slab grinding and fixing mechanism. Background Technique

[0002] Ceramic rock slabs are mainly used in the fields of home and kitchen boards. During the current production of rock slabs, it is often necessary to cut and grind the edges and corners of the rock slabs. During the grinding process of the rock slabs, a fixing mechanism is required to clamp and fix the rock slabs.

[0003] A Chinese patent with the publication number of CN 220994088 U discloses a fixing mechanism for rock slab processing and grinding, including a support frame. A support plate and a lead screw are installed inside the support frame. The lead screw is arranged above the support plate. The support plate rises or falls with respect to the support frame through a lifting component. A rock slab is placed above the support plate. The end of the lead screw makes an approaching or separating movement with respect to the rock slab. When the end of the lead screw abuts against the rock slab. Compared with the traditional method, this technical solution aims at the problem that when tiling at home, there is no suitable tool to fix the rock slab for processing during on-site processing of the rock slab. By using the support plate to lift the rock slab, and then clamping the rock slab through the lead screw and multiple suction cups. After stepping on the pedal and driving the support plate to descend, the rock slab can rotate with respect to the suction cup, so as to facilitate the processing operation of each side of the rock slab.

[0004] During the process of fixing the rock slab in cooperation with the grinding structure by the existing fixing mechanism, since it is necessary to grind the side wall of the rock slab, the rock slab cannot be limited in the horizontal direction, and the rock slab is prone to shaking, resulting in poor stability of the rock slab. Therefore, a rock slab grinding and fixing mechanism is proposed for the above problems. Content of the Utility Model

A second lead screw 19 is rotatably installed on the inner wall of the moving groove 18. A third knob 20 is welded to one side of the second lead screw 19. A moving block 21 is assembled in the moving groove 18. A moving frame 22 is welded to the moving block 21. A grinding wheel 23 is rotatably installed on the moving frame 22. A second motor 24 is installed on the moving frame 22 through a machine base. The output shaft of the second motor 24 is fixedly connected to the grinding wheel 23; during operation, in the process of fixing the rock slab 25 by the existing fixing mechanism in cooperation with the grinding structure, since the side wall of the rock slab 25 needs to be polished, the rock slab cannot be limited in the horizontal direction, and the rock slab is prone to shaking, resulting in poor stability of the rock slab 25. By placing the rock slab 25 on the turntable 4 and rotating the second knob 13, the first lead screw 12 is driven to rotate. The first lead screw 12 drives the two groups of sliders 14 on it to move relatively synchronously. The two groups of sliders 14 drive the two groups of sliding plates 15 to move relatively synchronously. The two groups of sliding plates 15 limit the rock slab 25 to the center of the turntable 4. At this time, the rotating rods 16 on the two groups of sliding plates 15 are in contact with the side wall of the rock slab 25, realizing the limitation of the rock slab 25 in the horizontal direction;

[0019] After that, rotate the first knob 9 to drive the screw rod 8 to rotate. While the screw rod 8 rotates, it moves vertically. The screw rod 8 drives the pressing plate 10 to move vertically downward. The pressing plate 10 presses the rock slab 25, realizing the clamping and fixing of the rock slab 25 by the pressing plate 10 and the turntable 4, and realizing the limitation of the rock slab 25 in the vertical direction;

[0020] After rotating the third knob 20, the second lead screw 19 is driven to rotate. The second lead screw 19 drives the moving block 21 to move horizontally. The moving block 21 drives the moving frame 22 to move horizontally.

By operating the second motor 24, the grinding wheel 23 is driven to rotate at a high speed. At the same time, the first motor 5 operates to drive the turntable 4 to rotate. The turntable 4 drives the rock slab 25 clamped thereon to rotate, realizing the grinding of the side wall of the rock slab 25. During this process, the side wall of the rock slab 25 is always in contact with the rotating rod 16, and the rotating rod 16 rotates, reducing the frictional resistance between the side wall of the rock slab 25 and the rotating rod 16. The two groups of rotating rods 16 limit the rock slab 25 in the horizontal direction, which is beneficial to improving the stability of the rock slab 25.

[0021] Working principle: During the process of fixing the rock slab 25 by the existing fixing mechanism in cooperation with the grinding structure, since the side wall of the rock slab 25 needs to be ground, the rock slab 25 cannot be limited in the horizontal direction, and the rock slab is prone to shaking, resulting in poor stability of the rock slab 25. By placing the rock slab 25 on the turntable 4 and rotating the second knob 13, the first lead screw 12 is driven to rotate. The first lead screw 12 drives the two groups of sliders 14 thereon to move synchronously relative to each other. The two groups of sliders 14 drive the two groups of sliding plates 15 to move synchronously relative to each other. The two groups of sliding plates 15 limit the rock slab 25 to the center of the turntable 4. At this time, the rotating rods 16 on the two groups of sliding plates 15 are in contact with the side wall of the rock slab 25, realizing the horizontal limit of the rock slab 25; then rotate the first knob 9 to drive the screw rod 8 to rotate. While the screw rod 8 rotates, it moves vertically. The screw rod 8 drives the pressing plate 10 to move vertically downward. The pressing plate 10 presses the rock slab 25, realizing the clamping and fixing of the rock slab 25 by the pressing plate 10 and the turntable 4, and realizing the vertical limit of the rock slab 25; after that, rotate the third knob 20 to drive the second lead screw 19 to rotate. The second lead screw 19 drives the moving block 21 to move horizontally. The moving block 21 drives the moving frame 22 to move horizontally. The moving frame 22 drives the grinding wheel 23 to move horizontally, so that the grinding wheel 23 is in contact with the side wall of the rock slab 25. By operating the second motor 24, the grinding wheel 23 is driven to rotate at a high speed. At the same time, the first motor 5 operates to drive the turntable 4 to rotate. The turntable 4 drives the rock slab 25 clamped thereon to rotate, realizing the grinding of the side wall of the rock slab 25. During this process, the side wall of the rock slab 25 is always in contact with the rotating rod 16, and the rotating rod 16 rotates, reducing the frictional resistance between the side wall of the rock slab 25 and the rotating rod 16.
