When the electrode cylinder assembling frame 2 moves to the alternating current circular seam welding machine 3 on the track 1, the first guide wheel 30.4 rolls along the guide vertical plate 29 to play a role in guiding and preventing derailment, the piston rod of the electric push rod 30.7 pushes against the top plate 30.8 on the second rectangular frame 30.5 to drive the second rectangular frame 30.5 to be far away from the guide vertical plate 29, so that the second guide wheel 30.6 is far away from the guide vertical plate 29, meanwhile, the tension spring 21 is stretched, a gap is reserved between the second guide wheel 30.6 and the guide vertical plate 29, and the smoothness of movement of the electrode cylinder assembling frame 2 is improved;

The working principle is as follows:

assembling an electrode cylinder: adjust two disc 2.3's interval to suitable position through adjustment cylinder 2.5, take a plurality of arc curb plates of electrode cylinder between two disc 2.3, enclose into cylindricly along disc 2.3, arrange long gusset respectively in two disc 2.3's notch again, long gusset is cliied by the rectangular plane edge of two arc curb plates, and the face of weld forms, and spot welding is fixed temporarily.

Before welding of the electrode cylinder: as shown in fig. 7, in this embodiment, the hand-operated wheel 8 is shifted, the two disks 2.3 are driven to synchronously rotate through the cylindrical gear 9, the transmission gear 11 and the sheet gear 10, the electrode cylinder on the disks 2.3 rotates in the reverse direction, any one lock biting block 22 on the sheet gear 10 presses the stop lever 20 downwards, the stop lever 20 is sleeved on the groove 23 to limit the rotation of the electrode cylinder, and the welding surface opposite to the limited lock biting block 22 corresponds to the wheel gap between the driving circular electrode 4.1 and the driven circular electrode 4.2.

When the electrode cylinder is welded: the electrode cylinder assembling frame 2 moves towards the alternating-current girth welding machine 3 along the track 1, before the electrode cylinder assembling frame 2 enters the alternating-current girth welding machine 3, the proximity switch 31 sends a signal to the electric push rod 30.7, the electric push rod 30.7 resets, the tension spring 21 retracts under the action of elasticity to drive the second guide wheel 30.6 to roll along the guide vertical plate 29, the second guide wheel 30.6 and the first guide wheel 30.4 clamp the guide vertical plate 29 tightly, friction on the guide vertical plate 29 is increased, the electrode cylinder assembling frame 2 moves more stably, and a welding surface can accurately and effectively enter a gap between the driving circular electrode 4.1 and the driven circular electrode 4.2;

as shown in fig. 1, in this embodiment, when the electrode cylinder assembly frame 2 carries the electrode cylinder to move right along the track 1, the pair of left welding wheels 4 on the ac girth welding machine 3 do not move, the welding surface of the electrode cylinder passes over the left welding wheels 4, and when the electrode cylinder moves to the pair of right welding wheels 4 on the ac girth welding machine 3, the right driving circular electrode 4.1 descends and rotates simultaneously to weld the welding surface;

after welding is finished, replacing a welding surface to be welded, manually rotating the stop rod 20 to withdraw from the previous groove 23, shifting the hand wheel 8 to drive the electrode cylinder to rotate, sleeving the next lock biting block 22 on the stop rod 20 through the groove 23 to limit the electrode cylinder to rotate, and finishing replacing the welding surface;

at the moment, the electrode cylinder assembly frame 2 can be backed, the second guide wheel 30.6 and the first guide wheel 30.4 are driven to clamp the guide vertical plate 29 by the proximity switch 31 in a similar manner, the friction on the guide vertical plate 29 is increased, the advancing stability of the electrode cylinder assembly frame 2 is improved, and a welding surface can accurately and effectively enter a gap between the driving circular electrode 4.1 and the driven circular electrode 4.2;

the electrode cylinder is carried to move leftwards along the track 1, the right pair of welding wheels 4 are reset and do not act at the moment, the welding surface of the electrode cylinder crosses the right pair of welding wheels 4, and when the electrode cylinder moves to the left pair of welding wheels 4 on the alternating current girth welding machine 3, the left driving circular electrode 4.1 descends and rotates simultaneously to weld the welding surface;

after the reciprocating movement, all the welding surfaces on the electrode tube are welded, and the electrode tube assembly holder 2 is returned to the initial position.

After the electrode cylinder is welded: the adjusting cylinder 2.5 drives one disc 2.3 away from the other disc 2.3 to remove the electrode cylinder.
