The working principle is as follows: when the welding device is used, during welding, the clamp body 11 clamps the hub body 12, the lifting mechanism 2 moves the moving plate 13 downwards to enable the welding head 17 to abut against the welding seam between the rim 1201 and the spoke plate 1202, then the first motor 18 is started, the rotation of the first motor 18 drives the rotating rod 14 and the welding head 17 to rotate, meanwhile, the clamp body 11 rotates the hub body 12 to achieve friction welding, meanwhile, the exhaust fan 304 is started to exhaust air, so that chips generated in the welding process are adsorbed and collected through the collecting pipe 303, the collected chips enter the collecting box 302, the adsorption force of the exhaust fan 304 on the chips in the collecting box 302 is reduced, at the moment, the chips can fall into the collecting box 302 to be collected uniformly, and the chips can be prevented from splashing under the combined action of the fixed cover 16, so that the welding device is safer, meanwhile, the collection of the scraps is more convenient;
the scraps collected in the collection box 302 fall on the upper side wall of the grinding plate 402 through the second through hole 406 and are adsorbed by the grinding plate 402, and meanwhile, when the rotating rod 14 rotates, the rotating disk 603 is driven to rotate through the connecting key 702, so that the protruding block 604 abuts against the side wall of the moving block 501, the sliding plate 405 is pushed to move, meanwhile, the first spring 504 contracts, when the protruding block 604 crosses the moving block 501, the sliding plate 405 is reset under the action of the first spring 504, the reciprocating movement of the sliding plate 405 can be realized, the collected scraps are ground and crushed, the crushed scraps are pushed into the first through hole 403 and adsorbed under the action of the first electromagnet 404, the use in the repair welding process is facilitated, and the effect and the efficiency in repair welding are ensured;
when the ultrasonic sensor 1003 detects a welding defect, repair welding needs to be performed on the defect, at this time, the second electromagnet 707 is electrified, the second electromagnet 707 attracts the moving ring 703 to move upwards after being electrified, so that the connecting key 702 moves upwards and is separated from the second key groove 708, meanwhile, the second spring 705 contracts, at this time, when the rotating rod 14 rotates, the rotating disc 603 does not rotate any more, namely, when feeding is performed, the sliding plate 405 does not move any more, the second through hole 406 is staggered with the first through hole 403, the sliding plate 405 seals the upper side of the first through hole 403, so that the crushed powder is prevented from being drawn away, at the same time, the first electromagnet 404 is powered off, at this time, the powder in the first through hole 403 enters the third through hole 805 through the fixing pipe 801, and the third electromagnet 1002 is electrified, so that the iron block 1001 is attracted, so that the sealing plate 804 moves towards the mounting cover 802, when third through-hole 805 and feed pipe 803 are aligned, the powder in third through-hole 805 passes through feed pipe 803 and gets into in the fixed cover 16 to fall on waiting to repair the welding region, carry out reuse with the piece that the welding produced, supply to repair the welding process, practice thrift the cost more, and, can guarantee that the volume of at every turn feeding is the volume of third through-hole 805, realize quantitative feed, avoid extravagant.
