[0037] Referring to Figures 1-4The mounting frame 1 is provided with a sealing detection assembly 3 at the top, the sealing detection assembly 3 comprises a gas transmission box 302 fixedly arranged on the mounting frame 1, the gas transmission box 302 is fixedly connected with a gas pump 301 at the top, one side of the gas transmission box 302 is provided with a gas pressure sensor 308, both sides of the gas transmission box 302 are fixedly connected with electric telescopic columns 303, the telescopic ends of the electric telescopic columns 303 are fixedly connected with adjusting plates 305, one side of the adjusting plate 305 is fixedly connected with mounting pipes 306, the gas outlet ends of the mounting pipes 306 are fixedly connected with sealing covers 307, and the adjusting plate 305 and the gas transmission box 302 are fixedly connected with gas guide hoses 304; The electric telescopic columns 303 push the sealing covers 307 to be tightly pressed on both sides of the pipeline, the gas pump 301 fills gas into the sealing space through the gas guide hose 304 and the mounting pipe 306, and the gas pressure sensor 308 monitors the gas pressure change in real time to judge whether the weld has a leakage; in this way, the welding and quality detection functions are integrated, the air tightness preliminary inspection can be directly completed on the equipment, the pipeline does not need to be moved to another station, the production cycle is greatly shortened, the efficient and integrated processing flow is realized, and defects can be found and processed in time.
[0038] In the implementation process of the present application, the pipeline to be welded is placed between the clamping blocks 508, then the driving motor 511 is started to drive the screw rod 509 to rotate, the driving blocks 510 on the screw rod 509 drive the movable sleeve 504 to move through the linkage frame 505, the movable sleeve 504 drives the lifting rod 503 to move downward through the linkage rod 506, the clamping blocks 508 at the bottom of the lifting rod 503 clamp and fix the pipeline, the position to be welded of the pipeline corresponds to the welding gun 422, then the operator adjusts the locking column 429 to make the transmission rod 417 and the limiting head 428 in sliding connection according to the contact type of the welded pipeline, then the driving handle 430 is rotated to drive the adjusting screw rod 426 to rotate, the adjusting block 427 on the adjusting screw rod 426 drives the limiting head 428 to move, and then the locking column 429 is rotated to make the transmission rod 417 and the limiting head 428 in fixed connection after the position of the limiting head 428 is adjusted; Since the limiting head 428 is located on the circular mounting disc 424 and the adjusting direction is moving along the diameter line of the mounting disc 424, when the limiting head 428 moves away from the center position of the mounting disc 424, the rotating radius of the limiting head 428 on the mounting disc 424 becomes larger, and after the adjustment is completed in this way, the mounting disc 424 rotates by the same angle at the same time, and then the stretching arm 415 is driven to move by the transmission rod 417, and the moving range is larger than the original position; Based on the above principle, when welding the V-groove type weld, first, the electric adjusting column 423 is extended to drive the welding gun 422 to move downward, so that the end of the welding gun 422 extends to the weld. Since the weld has a structure of being narrow at the bottom and wide at the top, when welding, the welding machine 431 is started to weld the deepest part of the weld through the welding gun 422, and at the same time, the reciprocating linear motor 406 can drive the driving rod 405 to move transversely and reciprocally, which can drive the welding gun 422 at the bottom of the bearing rod 414 to move transversely and reciprocally, and at the same time, the adjusting column drives the welding gun 422 to move upward. As the welding gun 422 moves upward, the effective welding width of the welding gun 422 cannot cover the wide weld, but the bearing rod 414 can drive the welding gun 422 to move transversely and reciprocally, thereby compensating for the defect that the width of the welding gun 422 cannot be adjusted, and ensuring comprehensive welding of the wide weld. At the same time, as the welding gun 422 moves upward, its welding width increases. In this process, the toothed rod 420 moves upward to drive the transmission gear 418 to rotate, the transmission gear 418 drives the mounting disc 424 to rotate, the limiting head 428 on the mounting disc 424 rotates to drive the telescopic arm 415 to retract through the transmission rod 417. When the sleeve 412 is moved transversely by the reciprocating linear motor 406 through the driving rod 405, the distance between the telescopic arm 415 and the limiting block 432 increases. During reciprocating movement, the bearing rod 414 cannot move when the telescopic arm 415 contacts the limiting block 432. In this case, as the telescopic arm 415 retracts, the width of the reciprocating movement of the welding gun 422 increases, thereby enabling uniform and comprehensive welding of the V-groove type weld.
[0039] The welding gun 422 in the present application can also be transversely arranged. In actual use, it can be inserted into the inside of the pipe to be welded, and the welding rod clamped by the end of the welding gun 422 can be butt-jointed with the inner wall of the pipe. The welding gun 422 can be rotated to weld the inner wall of the pipe.
