The working principle of the invention is as follows:

when the outer circular surface needs to be welded on the vertical grinding roller, and the roller sleeve 2 is rotated clockwise in the welding process, the driving rotating shaft 12 at the moment can drive the rotary platform 3 to rotate for 90 degrees, the rotary platform 3 can drive the roller sleeve 2 arranged on the rotary platform to rotate for 90 degrees, and the surfacing mechanism 5 at the moment can move to the right side of the position 16 of the welding end face of the roller sleeve 2 under the action of the upper and lower driving device 8 and the front and rear driving device 7.

At this time, a welding operator of the roller sleeve 2 is to install the middle support lug 31 between the two second side support lugs 33 in a hinged mode through the stud, and the stud is provided with a nut structure, the nut is loosened, so that the trigger mechanism 15 in the horizontal position can rotate 90 degrees around the stud, the rotating middle support lug 31 can drive the second fixing block 32, the first spring 30, the first telescopic rod 29, the fourth fixing block 19, the first side support lug 28, the cylindrical wheel 27, the connecting plate 26 and the first rack 38 to move, the first rack 38 is matched with the first rack hole 44 in the first fixing block 24, the second side support lug 33 is matched with the limiting plate 14 in a contact mode, the operator installs the limiting block 25 in place, the cylindrical wheel 27 can be matched with the outer circular surface of the roller sleeve 2 in a contact mode through the up-down driving device 8, the nut on the stud installed on the second side support lug 33 is screwed tightly, and therefore the first telescopic rod 29 cannot rotate around a hinge point on the middle support lug 31; on the other hand, when the operator rotates the adjusting knob 23, the fourth fixing shaft 77 is driven to rotate by the adjusting knob 23, the fourth fixing shaft 77 will sequentially drive the second bevel gear 57, the first bevel gear 55 and the third bevel gear 58 to rotate, the moving first bevel gear 55 will drive the second gear 82 to move, the second rack 56 will drive the second one-way block 63 to move, the first plate spring 75 will be in a pressed state at this time, the rotating third bevel gear 58 will drive the third rack 59 to move, the third rack 59 will drive the first one-way block 35 to move, the second plate spring 78 is in a pressed state, the first one-way block 35 and the second one-way block 63 at this time will not limit the rotation of the first fixing ring 53, so as not to limit the rotation of the gear ring 52 installed thereon, and at this time, the operator will mesh the first rack 38 with the gear ring 52.

The lock block 48 is inserted into the lock hole 37, the second spring 39 is under tension, and the brake rack 50 is inserted into the square hole on the brake block 49; then, the rectangular sliding block 81 is installed into the C-shaped block 79, at this time, the third spring 85 will be in a compressed state, and at the same time, the third leaf spring 86 is in a freely telescopic state, the second gear 82 and the fourth rack 72 are in a positional relationship, such that the fourth rack 72 moves downward and does not drive the second gear 82 to rotate, and the fourth rack 72 moves upward and drives the second gear 82 to rotate.

When the welding position is adjusted, an operator operates a driving device in the driving shell 46 to drive the overlaying structure to slide on the short cross beam 4, at this time, the driving shell 46 will sequentially drive the middle support lug 31, the second fixed block 32, the first spring 30, the first telescopic rod 29, the fourth fixed block 19, the first side support lug 28, the cylindrical wheel 27, the connecting plate 26 and the first rack 38 to move, since the cylindrical wheel 27 is located on the right side of the high point position 16 of the roller sleeve 2, the cylindrical wheel 27 will move in the direction of the first telescopic rod 29 under the restriction of the roller sleeve 2, so that the fourth fixed block 19 mounted thereon moves upwards, so that the connecting plate 26 and the first rack 38 move upwards, at this time, the first rack 38 will drive the gear ring 52 to rotate around the fixed column 51, the counterclockwise rotating gear ring 52 drives the rectangular teeth 54 mounted thereon to move, the rectangular teeth 54 will stride over the first unidirectional block 35 under the action of the first inclined plane 34 on the first unidirectional block 35, and the rectangular teeth 54 will stride over the first unidirectional inclined plane 34 on the second block 63, so that the second unidirectional fixed column 52 moves around the axis 51.

When the cylindrical wheel 27 crosses the high point 16 of the roller sleeve 2, the driving wheel at this time still drives the first gear 71 to make linear motion along the short beam 4, but under the thrust action of the first spring 30, the fourth fixed block 19 mounted thereon makes linear motion downward, so that the connecting plate 26 and the first rack 38 make linear motion downward, the first rack 38 at this time will drive the ring gear 52 to make rotary motion around the fixed column 51, the ring gear 52 rotating clockwise drives the rectangular teeth 54 mounted thereon to move, because the opening direction of the rectangular groove 36 is distributed opposite to the first inclined plane 34, the trigger block 80 mounted on the first one-way block 35 will make linear motion along the rectangular groove 36 under the thrust action of the rectangular teeth 54, the trigger block 80 making linear motion will drive the C-shaped block 79 mounted thereon to move, and the C-shaped block 79 will not play a role in limiting role for the rectangular sliding block 81 at this time, the pressed rectangular sliding block 81 will drive the fourth rack 72 mounted thereon to make a linear motion, the linear motion fourth rack 72 will drive the second gear 82 to make a linear motion, the second gear 82 will drive the first gear 71 to make a linear motion, under the reversing action of the first gear 71, the first gear 71 will drive the braking rack 50 to make an upward linear motion, the moving braking rack 50 will move out of the square hole of the braking block 49, the braking block 49 at this time will lose the restriction of the braking rack 50, under the action of the pulled second spring 39, the second spring 39 will pull the locking block 48 to make a linear motion, the locking block 48 will move out of the locking hole 37 on the clamping block 20, so that the locking block 48 loses the restriction of the wire feeder 18, at this time, the wire feeder 18 will not move in the direction of the short beam 4 under the action of the damping device therein, and the final position of the wire feeder 18 will be the axis of the gun head 22 on the wire feeder 18 and the vertical axis of the roller housing 2 The eccentric distance between the two grinding rollers is 2cm-3cm, so that the optimal position required by the vertical grinding roller welding process is achieved, and the surfacing quality is ensured.
