When the hydraulic cylinder 13 moves, it will drive the connecting block 14 to move toward the steel plate at the same time. At this time, the external water source is connected to the water inlet pipe 12 and then the water pump 11 is started to send water into the water outlet pipe 16 through the water pouring hose 18 and then flow out from the water outlet hole 17.

At this time, the end of the first spring rod 31 is lower than the bottom of the grinding disc 19 and will first contact the steel plate. When the grinding disc 19 continues to move toward the steel plate, the first spring rod 31 will shrink and drive the wire mesh 32 to shrink and move, so that the grinding area can be wrapped during grinding. In this step, the water outlet pipe 16 is set to connect the first spring rod 31 and the wire mesh 32, so that the grinding area can be wrapped when the steel plate is ground, and the debris generated during grinding will be blocked by the wire mesh 32 to reduce the metal debris generated during grinding from splashing around.

In this step, by setting the collecting holes 5 and the collecting box 51, some of the metal debris washed away can be collected, thereby reducing the situation where the debris remains on the top of the grinding table 111 and causes scratches on the steel plate due to contact with the steel plate.

[0029] like Figure 4As shown, a pair of slide rails 6 are fixedly connected to the inner wall of the polishing box 1; a filter screen 61 is placed on the inner wall of the slide rail 6; the slide rail 6 and the filter screen 61 are in sliding cooperation; the side wall of the collecting box 51 is connected to a drain pipe 62; during operation, when the washed metal debris enters the collecting box 51, it will be filtered by the filter screen 61 to separate the debris and water, and the debris will remain in the filter screen 61, and the water will continue to fall into the filter screen 61 and then be discharged from the drain pipe 62. When the filtering is completed, the filter screen 61 is pulled out of the slide rail 6, and the debris is cleaned and then the filter screen 61 is reset. In this step, the slide rail 6 is set to connect the filter screen 61 to filter the washed metal debris and water, and separate the water and debris, so as to reduce the debris entering the collecting box 51 and accumulating and remaining at the bottom, which is inconvenient to remove.

[0030] like Figure 4 As shown, a suction cup 7 is fixedly connected to the end of the second spring rod 42; during operation, when the second spring rod 42 clamps and fixes the steel plate from above, the suction cup 7 will contact and be adsorbed on the surface of the steel plate. In this step, the suction cup 7 is connected to the second spring rod 42, and can be adsorbed on the surface of the steel plate when the second spring rod 42 clamps and fixes the steel plate, so as to improve the tightness of the connection between the second spring rod 42 and the steel plate, and improve the clamping and fixing effect of the second spring rod 42 on the steel plate.

[0031] Working principle: When grinding the steel plate, place the steel plate on the surface of the grinding table 111, and then start the hydraulic cylinder 13 to drive the grinding disc 19 to move toward the steel plate to grind the steel plate. When the hydraulic cylinder 13 moves, it will drive the connecting block 14 to move toward the steel plate at the same time. At this time, connect the external water source to the water inlet pipe 12 and then start the water pump 11. Send the water into the water outlet pipe 16 through the pouring hose 18 and then flow out from the water outlet 17. At this time, the water outlet 17 is close to the surface of the steel plate, and water can be sprayed on the steel plate during grinding. When the moving component drives the grinding disc 19 to move, the water outlet pipe 16 will move at the same time, and start The reciprocating rotation of the motor 2 can drive the threaded rod 22 to rotate reciprocatingly, and at this time, the slider 23 can be driven to move reciprocatingly in the slideway 21, and at this time, the hydraulic cylinder 13 and the grinding disc 19 can be driven to move reciprocatingly on the surface of the steel plate for grinding. When the hydraulic cylinder 13 drives the water outlet pipe 16 to move toward the surface of the steel plate, it will drive the fixing ring 3 and the first spring rod 31 and the wire mesh 32 to move toward the surface of the steel plate at the same time. At this time, the end of the first spring rod 31 is lower than the bottom of the grinding disc 19 and will first contact the steel plate. When the grinding disc 19 continues to move toward the steel plate, the first spring rod 31 will shrink and drive the wire mesh 32 to shrink. The electric push rod 4 is started to drive the clamping plate 41 to move toward the side of the steel plate placed on the surface of the grinding table 111. When the inner wall of the clamping plate 41 contacts the side of the steel plate, the steel plate can be clamped and fixed from both sides. The second spring rod 42 is pulled up before clamping the steel plate. When the steel plate contacts the inner wall of the clamping plate 41, the second spring rod 42 is released. Under the effect of rebound, the end of the second spring rod 42 is pressed downward from the surface of the steel plate, and the steel plate can be clamped and fixed from above. After some metal debris generated during grinding is washed away, it will fall from the top of the grinding table 111 and then Then it falls from the collecting hole 5 to the collecting box 51 below. At this time, the collecting box 51 can collect the metal debris. When the washed metal debris enters the collecting box 51, it will be filtered by the filter 61 to separate the debris and water. At this time, the debris will remain in the filter 61, and the water will continue to fall into the filter 61 and then be discharged from the drain pipe 62. When the filtration is completed, the filter 61 will be pulled out of the slide rail 6, the debris will be cleaned and the filter 61 will be reset. When the second spring rod 42 clamps and fixes the steel plate from above, the suction cup 7 will contact and adsorb on the surface of the steel plate.
