When the height of the supporting plate 31 is adjusted to enable the vanadium-nitrogen alloy to be attached to the grinding wheel 2, firstly, the knob 76 is pulled downwards to drive the first gear 75, the movable shaft rods 59 and 58 to move synchronously, the moving block 72 slides synchronously in the moving groove 71 and extrudes the fixed block 73 made of rubber at the bottom end in the moving process of the movable shaft rod 59, the fixed block 73 generates elastic deformation to remove the limit of the moving block 72, then the knob 76 is pulled downwards to the limit, at this time, the moving block 72 moves to the limit in the moving groove 71 to remove the extrusion of the fixed block 73 at the top end, the fixed block 73 at the top end is restored to the original state under the action of self reducing force and limits the moving groove 71, the first gear 75 also moves to the state of being meshed with the second gear 77, the 58 is removed from being meshed with the second gear 57, at this time, the knob 76 is rotated to drive the second gear 77 to rotate, the threaded sleeves 78 fixedly connected with the second gear 77 are rotated, the two groups of threaded sleeves 78 are opposite in rotating direction at the moment, and meanwhile, due to the fact that the thread directions formed on the outer sides of the two groups of threaded rods 79 are opposite, the two groups of threaded sleeves 78 move upwards simultaneously to drive the supporting plate 31 to move upwards, the supporting plate 31 can be lowered by means of reverse rotation, the height of the supporting plate 31 can be adjusted, and the knob 76 is pushed upwards to the limit when the 58 and 57 are meshed again.
When the collecting assembly is to be disassembled and cleaned, firstly, the pull rod 45 is pulled downwards, the connecting sleeve 46 moves downwards under the action of the downward pull force, the movable sleeve block 44 is inserted into the movable cavity 42 and extrudes the movable spring 43, the movable spring 43 generates elastic deformation, then the connecting sleeve 46 and the collecting seat 41 are integrally pulled upwards, the inserting block 39 is separated from the inside of the slot 38, the disassembling of the collecting assembly can be completed, and the metal dust collected in the connecting sleeve 46 and the movable sleeve block 44 is dumped or recovered.
When dismantling the cleanness to collecting the subassembly, adapter sleeve 46 removes the inner wall that makes joint groove 48 and produces the extrusion to joint piece 49, makes joint piece 49 produce elastic deformation and removes and the joint between joint groove 48, makes joint piece 49 remove the spacing effect to adapter sleeve 46, then is opposite when will installing collecting the subassembly.
When the device main body 1 and the grinding wheel 2 are started, the motor 34 is also synchronously started to drive the fan blades 36 to rotate through the transmission belt 35, negative pressure is formed to collect dust generated when the vanadium-nitrogen alloy is ground, the dust generated during grinding enters the connecting sleeve 46 and the collecting seat 41 through the fixing frame 61, the dust is collected through the collecting seat 41 and the connecting sleeve 46, and the filter screen inside the collecting seat 41 plays a role in preventing the dust from running out of the bottom end of the negative pressure cavity 37.
