[0023] Among them, the casting is conveyed to the upper part of the grinding device 1 by the roller conveyor 2. When it is necessary to grind or cut, the pull rod is pulled. The pull rod drives the slider 62 to move, so that the grinding device 63 or the cutting device 64 is aligned with the power device 5. Specifically, by stepping on the foot pedal rod 51, the other end of the foot pedal rod 51 drives the lifting rod 54 to rise. Then the lifting rod 54 drives the lifting frame 56 and the top ring 58 to rise in turn, and the power motor 55 on the lifting frame 56 rises synchronously. The main split coupling 59 on the power rod of the power motor 55 rises and aligns and connects with the sub-split coupling 613 of the grinding device 63 or the cutting device 64. At the same time when the top ring 58 rises, it contacts the sliding ring 67 and is adsorbed by the adsorption force of the lower magnet sheet 510 and the upper magnet sheet 615. The top ring 58 drives the sliding ring 67 to rise or fall. Then the power motor 55 is started. The power motor 55 drives the main split coupling 59, the sub-split coupling 613 and the rotating shaft 69 to rotate. The rotating shaft 69 drives the cutting disc or the grinding disc to work. When cutting, it is best to place a height-fixing block under the foot pedal rod 51 to prevent the cutting wheel from swinging up and down. When the main split coupling 59 is separated from the sub-split coupling 613, the positioning magnets 614 on the main split coupling 59 or the sub-split coupling 613 respectively ensure the direction through the attraction force with the lower magnet sheet 510 or the upper magnet sheet 615. When the top ring 58 descends, the sliding ring 67 falls on the fixed block 61 and the top ring 58 can be disengaged from it by continuing to descend. Butter is injected into the oil ring groove 611 through the grease nipple 612 to prevent the sliding ring 67 and the sliding hole 65 from being worn. The accuracy of the alignment of the grinding device 63 or the cutting device 64 with the power device 5 is positioned by the cooperation of the bull's eye and the positioning hole. The lifting frame 56 is pulled down by the spring.
