[0036] In this embodiment, the rotation of the walking wheels 511 can drive the walking plate 51 to move annularly on the annular track 311, the walking plate 51 can drive the reciprocating guide rod 52 and the bearing seat 53 to move, and the bearing seat 53 can carry the welding gun, i.e. drive the welding gun to move annularly on the annular track 311; The bearing seat 53 can be adjusted on the traveling plate 51 to adjust the angle of the welding torch. The reciprocating guide rod 52 and the return spring 521 allow the reciprocating guide rod 52 to slide horizontally. The annular disturbance belt 312 causes the reciprocating guide rod 52 to slide horizontally back and forth on the traveling plate 51 when the traveling plate 51 moves in an annular motion, thereby driving the bearing seat 53 to swing back and forth. This enables the welding torch to swing back and forth during circumferential welding, resulting in a fish-scale weld and effectively improving the welding effect.

[0037] Working principle: During operation, the bellows component 6 is placed into the two first clamping mechanisms 2, and the two flange components 7 are placed into the second clamping mechanisms 3 respectively. Start the drive motor 41 and make the drive motor 41 rotate forward. At this time, the drive gear 411 rotates forward, which drives the first driven gear 421 to rotate forward and drives the second driven gear 431 to rotate in reverse. That is, it simultaneously drives the first drive gear 23 to rotate forward and the second drive gear 33 to rotate in reverse. When the first drive gear 23 rotates forward, multiple clamping plates 24 slide towards the axis of the first fixed disk 21 at the same time, so that the multiple clamping plates 24 clamp the bellows component 6. When the second drive gear 33 rotates in reverse, multiple clamping hooks 34 slide towards the outer edge of the second fixed disk 31, so that the multiple clamping hooks 34 hook the flange component 7 and fix the flange component 7. After the first clamping mechanism 2 fixes the bellows component 6 and the second clamping mechanism 3 fixes the flange component 7, no calibration is required. The bellows component 6 and the flange component 7 are coaxial. At this time, simply slide the first clamping mechanism 2 and the second clamping mechanism 3 horizontally to bring the bellows component 6 and the flange components 7 at both ends closer together, and you can prepare for circumferential welding. The angle of the support seat 53 can be adjusted on the walking plate 51 to adjust the angle of the welding gun. After the welding gun angle is adjusted, welding begins. At this time, the control motor 513 is started, and the control motor 513 drives the walking wheel 511 to rotate. The rotation of the walking wheel 511 can drive the walking plate 51 to move in a circle on the circular track 311. The walking plate 51 can drive the reciprocating guide rod 52 and the support seat 53 to move. The support seat 53 can carry the welding gun, that is, drive the welding gun to move in a circle on the circular track 311, thereby realizing the circumferential welding of the welding gun. Circumferential welding is performed simultaneously on the bellows component 6 and the flange components 7 at both ends, which effectively improves welding efficiency and ensures welding accuracy. During the circumferential welding process, the end of the reciprocating guide rod 52 that contacts the annular disturbance band 312 periodically enters the groove on the annular disturbance band 312, so that the reciprocating guide rod 52 slides horizontally back and forth on the traveling plate 51, thereby driving the bearing seat 53 to swing back and forth, so that the welding gun swings back and forth when performing circumferential welding, thereby welding fish scale weld and effectively improving the welding effect. After the welding is finished, the driving motor 41 is started and reverses, at this time, the driving gear 411 reverses, drives the first driven gear 421 to reverse, drives the second driven gear 431 to rotate forward, that is, drives the first driving gear 23 to reverse and the second driving gear 33 to rotate forward at the same time; When the first driving gear 23 reverses, the plurality of clamping plates 24 slide to the outside of the first fixed disc 21 at the same time, loosen the corrugated pipe component 6, when the second driving gear 33 rotates forward, the plurality of clamping hooks 34 slide to the axial direction of the second fixed disc 31, loosen the flange component 7, and facilitate the taking out of the corrugated pipe component 6 and the flange component 7 after the welding is finished; The first clamping mechanism 2 and the second clamping mechanism 3 are controlled by the driving mechanism 4 and are adjustable, not only facilitate the feeding and discharging of the corrugated pipe component 6 and the flange component 7 during the welding, but also make the first clamping mechanism 2 and the second clamping mechanism 3 adapt to different specifications and sizes of the corrugated pipe component 6 and the flange component 7.
