[0015] 1. The present invention sets a first cutting mechanism. After the stone plate slides to the right below the first cutting mechanism through a linear electric slide rail, the cylinder is started to drive the position of the B servo motor to drop, and then the position of the B servo motor is adjusted by the A servo motor so that the grinding disc on the B servo motor faces the side of the stone plate.

By setting a second cutting component, the electric push rod will drive the connecting block to move after starting, thereby driving the two sets of driving motors to move to the upper and lower sides of the stone plate respectively. After the driving motor is started, it will drive the grinding sheet to grind the upper and lower surfaces of the stone plate. By setting a B hydraulic lifter, the stone plate can be lifted up through the load-bearing plate, thereby grinding the area blocked by the anti-slip plate. During grinding, the load-bearing plate and the pressing plate will clamp the stone plate, thereby increasing the stability during grinding. Through the cooperation of the above structures, the six surfaces of the stone plate can be grinded at one time, thereby further improving the grinding efficiency.

[0017] 3. The present invention realizes real-time water spraying, cooling and cleaning of the stone slab by means of the universal nozzle and sewage pool. The water pump inside the water tank sprays clean water on the stone slab and the grinding disc through the universal nozzle, which effectively reduces the heat and friction generated during the grinding process and protects the service life of the stone slab and the grinding disc. At the same time, the sprayed clean water can also wash away the debris and dust generated by grinding, avoiding the pollution of dust to the environment and human body. The sewage pool is responsible for collecting and treating the sewage and waste residue generated during the grinding process, ensuring the cleanliness and hygiene of the working environment.

[0030] In the first embodiment, the second cutting mechanism 11 includes a position adjustment component 111, which includes a C servo motor 1111, a threaded rod 1112 and a slider 1113. The C servo motor 1111 is located inside the groove, one end of the threaded rod 1112 is fixedly installed at the output end of the C servo motor 1111, and the other end of the threaded rod 1112 is fixedly connected to the inner wall of the groove through a bearing;

[0031] Specifically, in this embodiment, we describe in detail how the first cutting mechanism 10 realizes multi-directional adjustment and polishing of the stone plate 5. First, the stone plate 5 to be processed is placed on the anti-slip plate 4, and is slid to the bottom of the first cutting mechanism 10 through the linear electric slide rail 2. The top surface of the support frame 1 is equipped with an electric blocking buckle to block the sliding plate 3, so that the position of the sliding plate 3 is fixed. At this time, the cylinder 101 is started, and the output end of the cylinder 101 drives the fixed plate 102 and the entire cutting mechanism below it to descend until the grinding disc approaches the side of the stone plate 5.

[0032] Next, the position of the fixed platform 104 is adjusted by the A servo motor 103 to ensure that the grinding disc is facing the surface of the stone plate 5 to be polished. The precise control of the A servo motor 103 allows the grinding disc to be fine-tuned at any angle to avoid the polishing effect being affected by the wrong grinding angle.

[0033] After the grinding disc is in contact with the surface of the stone plate 5, the B servo motor 105 is started to drive the grinding disc to rotate at high speed. At this time, the distance between the grinding disc and the stone plate 5 is further adjusted by the electric telescopic rod 106 to ensure the uniformity and consistency of the polishing effect;

[0034] Finally, the annular electric slide rail 9 is started to make the first cutting mechanism 10 slide along a predetermined track, so that the four sides of the stone plate 5 are evenly polished.

[0035] In the second embodiment, a hydraulic lifter 112 is fixedly mounted on the top surface of the slider 1113, a support plate is fixedly mounted on the output end of the hydraulic lifter 112, and an electric push rod 113 is fixedly mounted on the top surface of the support plate;

[0036] A connecting block 114 is fixedly installed at the output end of the electric push rod 113. The top and bottom surfaces of the connecting block 114 are provided with limit grooves 115. Adjustment plates 116 are arranged inside the two sets of limit grooves 115. The top surfaces of the two sets of adjustment plates 116 are provided with threaded grooves. A through hole is provided inside the connecting block 114, and a bidirectional screw 117 is installed in the through hole. The bidirectional screw 117 is threadedly connected to the two sets of adjustment plates 116.

[0037] The two sets of connecting blocks 114 are embedded with driving motors 118 on opposite sides, and the output ends of the two sets of driving motors 118 are installed with grinding sheets;

[0038] A square groove is provided at the center of the top surface of the sliding plate 3, and a mounting groove is provided at the center of the top surface of the supporting platform 6, and a B hydraulic lifter 12 is fixedly installed in the mounting groove, and a bearing plate 13 is fixedly installed at the output end of the B hydraulic lifter 12, and the area of ​​the bearing plate 13 is smaller than the area of ​​the square groove;

[0039] A C hydraulic lifter 14 is fixedly installed on the top surface of the top plate 8, a pressing plate 15 is fixedly installed on the output end of the C hydraulic lifter 14, an electric blocking buckle is installed on the top surface of the support frame 1, and the pressing plate 15 is located directly above the load-bearing plate 13;

[0040] Specifically, when it is necessary to polish the upper and lower surfaces of the stone plate 5, first, the electric push rod 113 is started to drive the grinding sheet to move to the center of the stone plate 5, and the drive motor 118 is started to drive the grinding sheet to grind the upper and lower surfaces of the center of the stone plate 5;

[0041] After the grinding of the center area of ​​the stone plate 5 is completed, the electric push rod 113 is started to move the adjustment plate 116 out of the area of ​​the stone plate 5, and then the B hydraulic lifter 12 is started to drive the load-bearing plate 13 to rise, thereby driving the stone plate 5 to leave the range of the anti-slip plate 4;

[0042] At this time, the C hydraulic lifter 14 is started, and its output end drives the pressing plate 15 to descend, pressing the stone plate 5 tightly against the load-bearing plate 13, thereby increasing the stability of the stone plate 5 during the polishing process;

[0043] Next, the electric push rod 113 in the second cutting mechanism 11 is started to push the connecting block 114 and the driving motor 118 above it to move along a preset trajectory to the upper and lower sides of the stone plate 5, and the driving motor 118 is started to drive the grinding sheet to synchronously polish the upper and lower surfaces of the stone plate 5.

[0044] Embodiment 3: A slide groove is provided on the top surface of the fixed platform 104, and a limit rod 16 is fixedly installed on the bottom surface of the fixed plate 102, and the limit rod 16 and the slide groove are slidably connected; a water tank 17 is fixedly installed on the top surface of the support platform 6, and a water pump is arranged inside the water tank 17, and a universal nozzle 18 is fixedly connected to the output end of the water pump, and a water outlet 19 is provided on the top surface of the sliding plate 3 and the support platform 6, and a sewage tank 20 is fixedly installed on the bottom surface of the support platform 6;

[0045] Specifically, during the polishing process, the water pump inside the water tank 17 sprays clean water evenly onto the stone plate 5 and the grinding disc through the universal nozzle 18. This water spraying method not only helps to reduce the heat and friction generated during the polishing process and protect the service life of the stone plate 5 and the grinding disc, but also can wash away the debris and dust generated by polishing to avoid dust pollution to the environment and human body;

[0046] At the same time, the top surfaces of the sliding plate 3 and the support platform 6 are provided with water outlet holes 19, so that the sprayed clean water can smoothly flow into the sewage pool 20 below. The sewage pool 20 is responsible for collecting and treating the sewage and waste residue generated during the grinding process, thereby ensuring a clean and hygienic working environment.

[0047] Working principle:

[0048] First, the sliding plate 3 is moved to the bottom of the first cutting mechanism 10 by the linear electric slide rail 2. During the movement, the electric blocking buckle will limit the sliding plate 3. After the sliding plate 3 is moved to the bottom of the first cutting mechanism 10, the cylinder 101 is started. The output end of the cylinder 101 drives the fixed plate 102 and the entire cutting mechanism below it to descend until the grinding disc approaches the side of the stone plate 5. Then, the position of the fixed table 104 is adjusted by the A servo motor 103 to ensure that the grinding disc is facing the surface to be polished of the stone plate 5. The A servo motor 103 Precise control allows the grinding disc to be fine-tuned at any angle to avoid the polishing effect being affected by the wrong grinding angle. After the grinding disc is in contact with the surface of the stone plate 5, the B servo motor 105 is started to drive the grinding disc to rotate at high speed. At this time, the distance between the grinding disc and the stone plate 5 is further adjusted by the electric telescopic rod 106 to ensure the uniformity and consistency of the polishing effect. Subsequently, the annular electric slide rail 9 is started to make the first cutting mechanism 10 slide along a predetermined track, thereby evenly polishing the four sides of the stone plate 5. After the side polishing is completed, The first cutting mechanism 10 is reset, the electric push rod 113 is started to drive the grinding sheet to the center of the stone plate 5, and the driving motor 118 is started to drive the grinding sheet to grind the upper and lower surfaces of the center of the stone plate 5. After the grinding of the center area of ​​the stone plate 5 is completed, the electric push rod 113 is started to move the adjustment plate 116 out of the area of ​​the stone plate 5, and then the B hydraulic lifter 12 is started to drive the load-bearing plate 13 to rise, thereby driving the stone plate 5 to leave the range of the anti-slip plate 4. At this time, the C hydraulic lifter 14 is started, and its output end drives the pressing plate 15 to descend, and the stone plate 5 is moved to the bottom of the plate. The stone plate 5 is tightly pressed against the load-bearing plate 13 to increase the stability of the stone plate 5 during the polishing process. Then, the electric push rod 113 in the second cutting mechanism 11 is started to push the connecting block 114 and the driving motor 118 above it to move along a preset trajectory to the upper and lower sides of the stone plate 5. The driving motor 118 is started to drive the grinding sheet to synchronously polish the upper and lower surfaces of the stone plate 5. During the entire polishing process, the water pump inside the water tank 17 will spray clean water on the stone plate 5 and the grinding disc through the universal nozzle 18. At this point, the entire workflow is completed.
