The use method of the invention comprises the following steps:

a. the chain 12 passes through the chain guiding devices 6 on two sides, the opening side of the chain ring is arranged on one side of the chain guiding device 6 close to the welding device 4, the chain ring to be welded is placed at the positioning table 503 of the positioning block 5, when the chain starts to be welded, the guiding chain can be installed at one end of the chain to be welded, the guiding chain is used as the chain after the welding is completed, and therefore the first chain ring to be welded is arranged at the positioning table 503.

b. The clapping slide plate drive 702 pushes the clapping slide plate 701 to move towards the direction of the chain ring, so that the end part of the upper clapping plate 703 and the end part of the lower clapping plate 704 are positioned at the upper side and the lower side of the chain ring, the clapping drive 707 drives the upper clapping plate 703 and the lower clapping plate 704 to be synchronously clamped, so that the chain ring at the positioning table 503 is clapped, at the moment, the chain rings at the two sides of the chain ring at the positioning table 503 are vertically clamped in the positioning groove 501, so that the chain ring to be welded is kept horizontal, and then the clapping device 7 is retracted.

c. The chain conveying plate 2 is pushed by the chain conveying drive 9 to move towards the welding device 4, so that the joint of the chain ring to be welded extends into the welding device 4.

d. The left side of the chain ring joint is pressed on a left fixed electrode 405 through a left movable electrode 408, the right side of the chain ring joint is pressed on a right fixed electrode 406 through a right movable electrode 410, a right support 403 is driven to move towards the left side through a traversing oil cylinder 404, the chain ring joint is pressed, the left fixed electrode 405 and the left movable electrode 408 are connected with a positive electrode of a power supply, the right movable electrode 410 and the right fixed electrode 406 are connected with a negative electrode of the power supply, and the joint is electrified to realize the resistance welding of the joint;

e. the chain feeding drive 9 drives the chain feeding plate 2 to retract to the original position, the two clamping blocks 302 are driven by the clamping drive 304 of the deburring device 3 to clamp the welded chain rings, the deburring drive 306 drives the deburring plate 305 to move towards the chain rings, when the upper guide wheel and the lower guide wheel move to the groove sinking position of the guide plate 307, the tension spring 316 drives the upper drive arm 308 and the lower drive arm 312 to rotate, the upper connecting rod 310 and the lower connecting rod 314 respectively drive the upper rotating arm 309 and the lower rotating arm 313 to rotate, so that the upper scraper 311 and the lower scraper 315 clamp the chain rings, the deburring plate 305 continues to move towards the chain rings, burrs and welding slag are removed by the upper scraper 311 and the lower scraper 315, then the deburring plate 305 reversely moves, so that the upper scraper 311 and the lower scraper 315 perform one more scraping operation, after the upper guide wheel and the lower guide wheel move out of the groove, the upper scraper 311 and the lower scraper 315 are separated from the chain rings, the two clamping blocks 302 are then driven apart from the chain link by the clamping drive 304;
