The working principle and the using process are as follows:
firstly, rotating a push rod 153 according to the distance value between two brake discs on a rear axle, wherein the push rod 153 drives a connecting disc 152 to rotate so as to drive a ball screw 151 to rotate, and finally driving two sliding tubes 2 meshed at two ends of the ball screw 151 to move in opposite directions so as to enable the distance value between two placing shafts 4 to be equal to the distance value between the two brake discs on the rear axle;
then the rear axle is placed on the top end of the placing shaft 4, after the rear axle is placed on the placing shaft 4, brake discs at two ends of the rear axle are contacted with the placing shaft 4, the rear axle is further supported, after the rear axle is placed on the placing shaft 4, the placing shaft 4 is pressed downwards by the self gravity of the rear axle, the placing shaft 4 is further driven to downwards move the pressing rod 6, when the pressing rod 6 is contacted with the front end of the rotating frame 8, the front end of the rotating frame 8 can be pressed downwards, the rotating frame 8 is further rotated upwards, when the placing shaft 4 is moved downwards until the limiting plate 5 is contacted with a supporting frame arranged on the top surface of the sliding pipe 2, the supporting frame is fixedly arranged on the top surface of the sliding pipe 2 and is positioned at one side of the driving gear 233 close to the placing shaft 4, the supporting frame is staggered with the driving gear 233 and the driven gear 13 in the horizontal direction, the placing shaft 4 is moved downwards to the lowest point, and the rear end of the rotating frame 8 is positioned in a vertically upward state, the rubber wheel 11 is driven to be right above the rear axle, the connecting rod 9 can be pulled downwards through the elasticity of the compression spring 12, and the connecting rod 9 drives the rubber wheel 11 to be pressed on the top end of the rear axle through the mounting rack 10;
when the placing shaft 4 moves downwards, the communicating valve pipe 25 is in a closed state, the downward movement of the placing shaft 4 presses the hydraulic oil in the inner cavity of the sliding pipe 2 into the fixed oil tank 17 to push the piston assembly 20 to move upwards, after the placing shaft 4 moves downwards to the lowest point, the communicating valve pipe 25 is opened, the fixed oil tank 17 is communicated with the auxiliary oil tank 18, the weight of the piston assembly 20 presses the hydraulic oil into the auxiliary oil tank 18 through the communicating valve pipe 25, and meanwhile, the tooth grooves 22 are driven to move downwards;
the tooth socket 22 is meshed with the driving gear 232 to drive the rotating shaft 231 to rotate so as to drive the driving gear 233 to rotate, at the moment, the placing shaft 4 is located at the lowest point, the driven gear 13 is meshed with the driving gear 233, the driven gear 13 is driven to rotate when the driving gear 233 rotates, so that the roller 24 is driven to rotate in the inner cavity of the placing shaft 4, the roller 24 is in contact with the bottom end of the brake disc, so that the brake disc can be driven to rotate, the rear axle is driven to rotate, the periphery of the rear axle is rotated to the front side of the bottom plate 1 at the same speed, and an operator can conveniently polish the rear axle;
after polishing is finished, the rear axle is directly taken out upwards, the rear axle drives the rotating frame 8 to rotate backwards through the rubber wheel 11, and the rear axle leaves the upper part of the rear axle and cannot be prevented from moving upwards;
when the rear axle is taken out, the elastic force of the return spring 16 drives the lifting plate 3 to move upwards, so that the placing shaft 4 is pushed to return, the hydraulic oil in the auxiliary oil tank 18 is pumped into the sliding pipe 2, and finally the communication valve pipe 25 is closed.
