The using method comprises the following steps:

the carrier block 6 is placed on the belt of the transmission belt 4, a plurality of rotors 10 are vertically inserted and fixed at the top of the carrier block 6 and are sequentially distributed from left to right, correspondingly, through holes 61 with the same number are formed between the outer walls of the front side and the rear side of the carrier block 6, each through hole 61 is positioned below one corresponding rotor 10, after the transmission belt 4 is started to run, the transmission belt 4 can drive the carrier block 6 to move from left to right between two baffles 9 positioned on the transmission belt 4, when one through hole 61 on the rightmost side of the carrier block 6 moves to the position sensor 8, the sensing end of the position sensor 8 can drive the telescopic end of the positioning cylinder 7 to extend outwards until the telescopic end of the positioning cylinder 7 is inserted into the through hole 61, and thus the continuous movement of the carrier block 6 is prevented to realize positioning.

Then, the telescopic ends of the driving feeding cylinders 55 are extended outwards to drive the two grinding units to translate towards the direction of the carrier block 6 by means of the moving plate 54 and the frame 58, meanwhile, the grinding motors 59 in the two grinding units are started to enable the rotating shafts of the two grinding units to rotate in opposite directions, the rotating shaft of each grinding motor 59 drives the driving shaft 511 to rotate in the shaft sleeve 510, the driving pulley 512, the driven pulley 515 and the belt 513 further drive the driven shaft 514 to rotate, and therefore the grinding wheel 516 is driven to rotate, and burrs at the end portions of the two grinding units are ground when the grinding wheels 516 in the two grinding units are contacted with the end portions of the rotor 10.

In the polishing process, the telescopic ends of the two lifting cylinders 537 in each lifting unit can be driven to extend outwards, so that the lifting beams 538 in the two lifting units are driven to move downwards, the frame 532 is driven to move downwards by virtue of the balance beam 539 and the two connecting columns 5311 in each lifting unit, the main body 5 is driven to move downwards by virtue of the traction plate 51, the grinding wheels 516 in the two polishing units are driven to move downwards, and the polishing height is adjusted; conversely, the telescopic ends of the two lifting cylinders 537 in each lifting unit can be driven to retract inwards to drive the two grinding wheels 516 to move upwards.

The servo motor 531 is started to rotate the rotating shaft, and then the driving head 5310 drives the adjusting shaft 533 to rotate, so that the cylindrical head 535 is driven to eccentrically rotate in the groove 5361 on the traction block 536, and then the traction block 536 is driven to reciprocate left and right, so that the traction plate 51 reciprocates left and right by means of each guide rail 5312 and a plurality of sliding blocks 5313 on each guide rail 5312, and then the two grinding wheels 516 are driven to reciprocate left and right, and burrs at the end part of the rotor 10 are polished better and faster.
