In this embodiment, the polishing device 4 includes a driving shaft 41, a sleeve 42 and a polishing motor 43, the top fixedly connected with polishing disc 44 of the driving shaft 41, the bottom of the polishing disc 44 is provided with a polishing head 45, the driving shaft 41 is provided with a section of spline, the sleeve 42 is rotationally connected with the frame 1, and the center of the sleeve is provided with a spline groove 421 for sliding the spline, the sleeve 42 rotates, the driving shaft 41 also rotates due to the fact that the sleeve 42 and the driving shaft 41 are matched with each other through the spline and the spline groove 421, the top of the sleeve 42 is provided with a belt pulley 46, the polishing motor 43 is fixedly connected with the frame 1, and the output shaft of the polishing motor is also provided with the belt pulley 46, and the two belt pulleys 46 are connected through a belt.
In this embodiment, the polishing head 45 is a rotating body, and the cross section of the polishing head is attached to the rail groove.
In this embodiment, the lifting device 5 includes a lifting motor 51 and a second screw 52, the lifting motor 51 is fixedly connected to the frame 1, a third synchronizing wheel 53 is fixedly connected to an output shaft of the lifting motor 51, the second screw 52 is in threaded connection with the top plate 12, and a fourth synchronizing wheel 54 is disposed at the bottom of the second screw, when the second screw 52 rotates in the forward direction, the second screw 52 moves downward, and vice versa, the fourth synchronizing wheel 54 rotates and is connected to the driving shaft 41, and the third synchronizing wheel 53 is connected to the fourth synchronizing wheel 54 through a synchronous belt.
The working process and the principle thereof are as follows:
the initial sanding head 45 is in the uppermost position and the two carriages are in the distanced position, at which time the spacing between the positioning wheels 27 on different sides is greater and the track can be placed in the middle position.
The frame 1 is placed on a track, so that the traveling wheels 11 are in contact with the track, then the driving motor 31 is started, the driving motor 31 is started to drive the driven gear 34 through the driving gear 33, so that the rotating shaft 32 rotates, the rotating shaft 32 drives the two synchronizing wheels 35 to rotate, and the two synchronizing wheels 35 drive the first synchronizing wheel 24 to rotate on the fixing plate 21.
Because the first synchronizing wheel 24 is in threaded connection with the first screw 23, and the turning directions of the two first screws 23 are opposite, when the first synchronizing wheel 24 rotates, the two first screws 23 can move inwards, so that the two wheel carriers 22 are close to the side wall of the middle of the track, the middle of the track is clamped by the positioning wheel 27, and the driving motor 31 is turned off after clamping is finished. The support rod 25 is used to ensure that the wheel frame 22 can slide smoothly.
When the two positioning wheels 27 clamp the middle of the rail, the polishing head 45 is facing the rail groove, and then the polishing motor 43 is started, the polishing motor 43 transmits power to the sleeve 42 through the two pulleys 46, the sleeve 42 rotates, and the driving shaft 41 also rotates because the spline is matched with the spline groove 421 between the sleeve 42 and the driving shaft 41.
The second screw 52 remains stationary when the elevator motor 51 is turned off, so that the driving shaft 41 can be maintained at a certain height.
When the lifting motor 51 is started, the synchronous wheel III 53 drives the synchronous wheel IV 54 to rotate in the forward direction, the synchronous wheel IV 54 drives the screw rod II 52 to rotate, and the screw rod II 52 is in threaded connection with the top plate 12, so that the screw rod II 52 moves downwards when the screw rod II 52 rotates in the forward direction, and the driving rod is driven to move downwards in the sleeve.
Because the surfacing layer is thicker, and the degree of depth is darker, so can move down certain degree of depth with the actuating lever earlier, carry out preliminary polishing to the surfacing layer of this degree of depth, utilize handle 13 to promote the automobile body forward when polishing, locating wheel 27 can guarantee with walking wheel 11 that the automobile body can normally move, polish through the back, recycle elevating gear 5 makes drive shaft 41 continue to descend a degree of depth, polish once more, thereby fall into the surfacing layer and polish several times, reduce the resistance and the degree of difficulty when polishing.
The abrasive disk 44 may then abrade any weld overlay that overflows the top surface of the rail.
After the grinding is finished, the grinding motor 43 is started in a reverse rotation mode, so that the driving shaft 41 is lifted to drive the grinding head 45 and the grinding disc 44 to reset, then the driving motor 31 is started in a reverse rotation mode, so that the two first screw rods 23 are mutually arranged, the wheel frame 22 is far away from the track, and then the vehicle body can be taken down from the track.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
