simultaneously, second place induction installation 15 sends the motor-car wheel to reaching maintenance station signal to electrical control cubicles 13,5 actions of electrical control cubicles 13 control lifting bodies, the piston rod of jacking cylinder 51 jack-up that makes progress is held motor-car wheel to rising by the V-type tray 52 of upper end, until shaft end nut and device for screwing up 2 to pull the grip assembly position relative.The 3rd position induction device 16 that is located at jacking cylinder 51 housing tops one side simultaneously sends the motor-car wheel to arriving the assembling position signal to electrical control cubicles 13, clamping cylinder 64 actions in the electrical control cubicles 13 control clamping devices 6, its piston rod elongation drives first arm of force 62 and second arm of force 63 inwardly rotates, and is right by the fixture block 65 clamping motor-car wheels on its top.After clamping puts in place, operating personnel are by 12 actions of switch board 13 control displacement cylinders, its piston rod elongation drives device for screwing up 2 by holder 10 and advances along slide rail 11, pull the fast contact of cover end face when going up the motor-car wheel when device for screwing up 2 front ends to shaft end nut, displacement cylinder 12 stops elongation, operating personnel rotate the cover of pulling of device for screwing up 2 front ends with hand, make to pull to overlap and just in time rush to shaft end nut, drive device for screwing up 2 by displacement cylinder 12 again and move on this moment, until pulling cover and shaft end nut fully to good position, at this moment, operating personnel can start the servomotor work in the device for screwing up 2, drive to pull the tightening operation that cover is finished shaft end nut.After the shaft end nut assembling operation was qualified, the servomotor of device for screwing up 2 quit work, 12 actions of electrical control cubicles 13 control displacement cylinders, and its piston rod drives device for screwing up 2 by holder 10 and moves backward, makes device for screwing up 2 front ends pull cover and withdraws from.When treating that holder 10 touches the 5th position induction device 18 on the frame 9, the 5th position induction device 18 sends device for screwing up and has withdrawed from the signal that puts in place, clamping cylinder 64 actions in the electrical control cubicles 13 control clamp mechanism 6, its piston rod retraction drives first arm of force 62 and second arm of force 63 outwards rotates, make the fixture block 65 on its top unclamp motor-car take turns right.Electrical control cubicles 13 is controlled jacking cylinder 51 actions in the lifting bodies 5 then, and its piston rod decline drives V-type tray 52 and slowly motor-car taken turns putting down, and takes turns falling on the rail up to motor-car.The motor-car wheel is to after falling the position, the 3rd position induction device 16 of jacking cylinder 51 housing tops one side sends the motor-car wheel to falling a signal, if this moment is next station free time, the then first gear wheel cylinder, 304 actions in the electrical control cubicles 13 controls first gear wheel mechanism 3, its piston rod retraction cooperates by first connecting rod 305 and second connecting rod 306, and the buffer stop device that drives swing arm 303 ends falls.After falling to putting in place, thumb wheel cylinder 71 actions in the electrical control cubicles 13 control thumb wheel mechanisms 7, its piston rod are risen and are driven push rod 72 and rotate around bearing 73, the rear portion of push rod 72 jack-up that makes progress, stir the motor-car wheel and leave the maintenance station, finish out the wheel action it is advanced along rail.When treating that motor-car wheel touches the 4th position induction device 17 under its rear portion rail to crossing the first gear wheel mechanism 3, the 4th position induction device 17 sends the motor-car wheel to going out to overhaul the station signal, thumb wheel cylinder 71 actions in the electrical control cubicles 13 control thumb wheel mechanisms 7 at this moment, its piston rod decline drives push rod 72 and resets, and finishes once to the right assembling operation task of motor-car wheel.When treating that new motor-car wheel overhauls needs, can repeat above-mentioned steps, finish the right assembling operation of next motor-car wheel.
