[0012] Technical effects and advantages of the present invention: The present invention automatically conveys the stone material through the stone conveying mechanism before the stone material is polished. When the stone material needs to be polished, the stone material to be polished can be placed on the conveyor belt at the top of the mounting frame, and the feeding motor is turned on so that the transmission shaft drives the conveyor belt to convey the stone material to be polished, thereby conveying the stone material to be polished to the top of the mobile positioning platform. Before the conveying, the positioning clamping plate is driven by the driving hydraulic cylinder to retract into the inside of the mounting groove, so that the conveying of the stone material to be polished by the conveyor belt will not be affected. When the stone to be polished is moved and transported, the present invention performs the conveying operation through the stone conveying mechanism. After the stone to be polished is transported to the top of the mobile positioning platform through the conveyor belt, the driving hydraulic cylinder inside the installation groove is first opened so that the hydraulic cylinder driving shaft drives the positioning clamping plate to move upward, and at the same time, the two groups of positioning motors on both sides of the mobile positioning platform are turned on to rotate the two groups of positioning screw rods, and then the two groups of positioning nuts are driven to move closer to each other under the rotation action of the positioning screw rods, and the movement of the positioning nuts will drive the movable block and the positioning clamping plate to move closer to each other, so that the four The positioning clamp is assembled to clamp and fix the stone to be polished, which increases the stability of the stone to be polished during the polishing process and the upward movement process. After the stone to be polished is fixed on the top of the mobile positioning platform, the conveying motor inside the support box is turned on again to rotate the conveying screw rod, and then under the rotation of the conveying screw rod, the conveying nut is driven to move upward along the outer wall of the conveying screw rod. Under the movement of the conveying nut, the fixed block, the mobile positioning platform and the stone to be polished are synchronously driven to move upward until the stone to be polished is moved to the top of the polishing platform, which is convenient for the polishing operation. When the stone to be polished is being polished, the polishing work is performed by adjusting the polishing mechanism. When the stone to be polished moves to the top of the polishing table, the polishing hydraulic cylinder inside the installation box is opened, so that the lifting rod drives the polishing box to move downward. When the polishing box moves downward, the polishing motor inside the polishing box is turned on, so that the motor driving shaft drives the polishing disc to rotate, thereby the stone to be polished on the top of the polishing table is polished by the polishing disc. During polishing, the water pump at the top of the cooling water tank can be turned on at the same time, so that the water pump pipe draws the cooling water inside the cooling water tank into the drain pipe, and then the cooling water is discharged from the cooling nozzle at the bottom of the drain pipe, thereby cooling the polishing of the polishing disc. At the same time, when it is necessary to adjust the front and rear polishing positions of the polishing disc with respect to the stone to be polished, the first adjusting motor inside the first adjusting box can be turned on. The first adjusting screw is rotated, and then the rotation of the first adjusting screw will drive the first screw nut to move straightly left and right along the outer wall of the first adjusting screw. Under the movement of the first screw nut, the moving block, the second adjusting box and the grinding disc will be synchronously driven to move straightly left and right, so that it is convenient for the user to adaptively adjust the front and rear grinding positions of the grinding disc. When it is necessary to adjust the left and right grinding positions of the grinding disc, the second adjusting motor inside the second adjusting box can be turned on to make the second adjusting screw rotate, and then under the rotation of the second adjusting screw, the second adjusting nut will be driven to move straightly left and right along the outer wall of the second adjusting screw. At the same time as the second adjusting nut moves, the sliding block and the grinding disc will be driven to move left and right synchronously for adjustment, so that it is convenient for the user to adaptively adjust the left and right grinding positions of the grinding disc. When grinding stone, the present invention can automatically replace the required grinding disc according to the smoothness required for grinding through the automatic replacement mechanism, wherein when the grinding disc needs to be replaced, the height of the grinding disc is adjusted to a suitable replacement height through the grinding hydraulic cylinder and the lifting rod, and then the first adjusting motor is turned on, and the grinding disc is driven to move toward the replacement box through the first adjusting screw rod and the first screw rod nut until the grinding disc is moved to the placement groove on one side of the replacement box, and then the driving motor is turned on to make the bidirectional adjusting screw rod rotate, and under the rotation action of the bidirectional adjusting screw rod, the two adjacent groups of moving nuts on the outer wall of the bidirectional adjusting screw rod are driven to move closer to each other, and the movement of the two groups of moving nuts will drive the moving plate, the connecting arm and the fixed splint to move closer to each other, and the grinding disc is clamped and fixed by the two groups of fixed splints. The second adjusting motor is then turned on to drive the motor drive shaft to move left or right to a suitable top of the grinding disc, and then the motor drive shaft is driven downward by the grinding hydraulic cylinder and the lifting rod, and the grinding motor is turned on at the same time, so that the mounting screw is installed into the threaded groove at the bottom end of the motor drive shaft again. At this time, the driving motor is turned on again, so that the two-way adjusting screw and the moving nut drive the moving plate, the connecting arm and the fixed splint to move in the opposite direction, so that the fixed splint releases the grinding disc, and the replaced grinding disc can be taken out of the placement slot, which is convenient for the user to automatically replace the grinding disc; After the stone is polished, the present invention collects the polished stones in a centralized manner through the automatic unloading mechanism and the stone transmission mechanism, which is convenient for users to carry out centralized processing. When the stone to be polished on the top of the mobile positioning platform is polished, the unloading hydraulic cylinder inside the fixed plate at one end of the polishing platform is opened, so that the telescopic driving rod drives the unloading push plate to move to the right. When the polished stone is pushed onto the conveyor belt by the unloading push plate, the first transmission motor and the second transmission motor are turned on, so that the polished stone can be transported to the transmission port through the transmission belt and the conveyor belt, which is convenient for users to carry out centralized processing.
