In the in-process of diffusion, fixed block 296 can pass through the trompil position, and in trompil department, the inspiratory air current of second sucking disc 298 department hinders and reduces, and air current speed can correspondingly increase, and the position of each trompil on disc surface is confirmed through the diffusion to the velocity of flow inductor, and in trompil department, the dead lever begins to rotate, carries out the overlay type measurement to whole trompil position to confirm the central point of each trompil according to the minimum that the air current hinders, through the silencer model contrast of trompil position and database inside, confirm that the disc puts the angle. When the circular tube is welded, the fixing blocks 296 are retracted toward the center, the fixing rod 291 is inserted into the circular tube, the fixing blocks 296 are expanded, the circular tube is sucked from the inside by the first suction cup 297, the circular tube is sequentially sent to the position of the hole, and the circular tube is welded. The fixing unit 29 determines the angle position of each disc in the welding process of the silencer through the change of the flow velocity of the negative pressure airflow, so that the adjustment of the disc position improves the welding precision on one hand, and the confirmation of the position of the hole on the surface of the disc can assist the fixing unit to avoid each hole position on the other hand, thereby improving the stability of the disc. The fixing unit 29 of the invention can fix and move the disc and the circular tube in sequence through the same fixing mechanism, greatly reduces the number of parts in a limited space, and reserves sufficient clearance for the welding process.
As shown in fig. 4, the first suction cup 297 and the second suction cup 298 are covered with an elastic pad 299, and the elastic pad 299 is provided with an annular ring, which is respectively communicated with the first suction cup 297 and the second suction cup 298. The elastic pad 299 is arranged so that the fixing block 296 can deform according to the contours of the disc and the inner wall of the circular tube when contacting the disc and the inner wall of the circular tube, the elastic pad 299 is tightly combined on the wall surface, and the disc and the circular tube can be fixed more stably only by the first suction cup 297 and the second suction cup 298.
As shown in fig. 5, the housing conveying line 34 is provided with a fixing claw 341. The fixing claws 341 fix the housing of each muffler, move along the housing conveying line 34, stop the movement of the housing conveying line 34 when reaching the welding position, fix the tubular housing of the muffler, release the housing when the welding is completed, and convey the muffler onto the blanking conveying belt 32 by the conveying robot 33.
The working principle of the invention is as follows: the carrying manipulator carries the disc on the locating component, fixed unit 29 passes through the change of the negative pressure airflow velocity of flow, the angular position of each disc in the silencer welding process has been confirmed, the fixed block adsorbs the disc, the removal axle drives the disc and rotates, after the position adjustment, the slide plate drives the disc and gets into the tubulose shell, the ring moves the part and drives the welder part and remove, carry out annular welding to the ring, after the welding finishes, the carrying manipulator carries each pipe again on the locating component in proper order, fixed unit stretches out the inside of the pipe, it is fixed with the pipe, the pipe moves during each disc hole thereupon, the welder part is with pipe and disc welding. When the sectional area of the welding wire is increased, the size of the hole in the friction ring is increased, but the friction ring body is clamped by the two light ring rings, the friction ring can be compressed and contracted, the density of the friction ring in unit area is increased, the friction force of the friction ring 123 acting on the welding wire is increased, the resistance of the welding wire in advancing is increased, and the welding wire conveying speed is reduced. After welding, the conveying manipulator 33 conveys the silencer to the blanking conveyor belt 32, and the blanking conveyor belt 32 conveys the silencer to a subsequent station.
