[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention arranges an adjusting component, places two sheet metal parts on the mounting plate to fix the pressing plate, and rotates the adjusting block to drive the two connecting blocks to rotate in the opposite direction in the notch through the adjusting block, and at the same time the fixing rod moves in the limiting mechanism, so that the two connecting blocks respectively drive the two adjusting seats to move in the opposite direction in the sliding groove, so as to adjust the height of the two adjusting seats, thereby avoiding the situation when the sheet metal parts are butt-welded, because the fixing plates on the welding devices of the existing devices are mostly arranged at the same horizontal height, so when the two sheet metal parts are butt-welded, it is necessary to butt-weld the bottom of one sheet metal part with the top of the other sheet metal part, and the height of the sheet metal parts needs to be adjusted with the help of an external pressing plate, which increases the operation time of the staff and reduces the work efficiency during the welding work.

[0016] 2. The present invention sets a limit mechanism. When two sheet metal parts are butt-welded, the adjusting block is rotated, and the adjusting block drives the ratchet to rotate in the limit groove through the fixed rod, so that the ratchet and the fixed block are limited and squeezed, and the ratchet limits and fixes the rotation angle of the adjusting block, so that the adjusting seat can adjust the relative height according to the height of different sheet metal parts. At the same time, when the height of the two adjusting seats needs to be adjusted horizontally, the limit plate is pulled, so that the limit plate drives the round rod to move upward, and at the same time, the limit plate drives the fixed block and the ratchet to release the limit through the limit rod, so that the adjusting block can be rotated to rotate in the opposite direction, so that the adjusting block drives the two adjusting seats to rotate and reset.

[0017] 3. The present invention sets a contact component. When the scraper is squeezing the waste chips stuck in the mesh at the top plate, the scraper can slide out in the moving groove. Therefore, when the top plate ejects the impurities, the scraper can adaptively adjust the size of the scraper sliding out of the moving groove according to the squeezing force of the impurities stuck in the mesh on the top plate, so that the scraper cleans and scratches the inner wall of the mesh, thereby avoiding that the scraper contacts and scratches the inner wall of the mesh for a long time when the top plate ejects the impurities stuck in the mesh, thereby causing friction damage to the inner wall of the mesh. When working for a long time, the inner wall of the mesh will expand, thereby reducing the service life of the filter plate.

[0018] 4. The present invention sets a filtering mechanism. When the exhaust gas generated during welding enters the collection box, the exhaust gas entering the collection box is sucked into the filter housing through the filter, filtered through the filter layer and then discharged. At the same time, the scraper assembly generates suction through the filter, so that the scraper drives the fourth spring to move toward the second connecting plate, so that the scraper assembly cleans the inner wall of the filter housing, thereby preventing the exhaust gas from passing through the filter housing for a long time and the impurities in the exhaust gas from adhering to the inner wall of the filter housing.

[0046] When two sheet metal parts are butt-welded, the adjusting block 45 is rotated, and the adjusting block 45 drives the ratchet 443 to rotate in the limiting groove 442 through the fixing rod 48, so that the ratchet 443 and the fixing block 448 are limited and squeezed, so that the ratchet 443 limits and fixes the rotation angle of the adjusting block 45, so that the adjusting seat 41 can be relatively adjusted in height according to the height of different sheet metal parts. At the same time, when it is necessary to adjust the height of the two adjusting seats 41 horizontally, the limiting plate 445 is pulled, so that the limiting plate 445 drives the round rod 447 to move upward, and at the same time, the limiting plate 445 drives the fixing block 448 and the ratchet 443 to release the limit through the limiting rod 444, so that the rotating adjusting block 45 can rotate in the opposite direction, so that the adjusting block 45 drives the two adjusting seats 41 to perform rotation and reset work;

[0047] When welding sheet metal parts, the suction machine 52 is turned on, and the suction force generated by the suction machine 52 drives the ejection mechanism 53 to move downward, so that the waste gas and welding slag generated during the welding work pass through the filter plate 54 and enter the baffle 55 for collection, and the waste gas entering the collection box 51 is filtered and discharged through the filter mechanism 56;

[0048] When the welding work on the sheet metal is completed, the second spring 533 is stretched to drive the ejector frame 531 to reset upward, so that the ejector frame 531 drives the contact assembly 534 to move toward the filter plate 54, thereby preventing the waste generated during welding from being stuck in the mesh of the filter plate 54;

[0049] When the second spring 533 is stretched and drives the ejection frame 531 to reset upward, the ejection frame 531 drives the contact rod 5341 to move upward, so that the top plate 5345 on the contact rod 5341 moves to the mesh of the filter plate 54. When welding slag and waste are stuck in the mesh of the filter plate 54, the top plate 5345 and the waste stuck in the mesh are offset. At the same time, when the ejection frame 531 drives the contact rod 5341 to move upward continuously, the top plate 5345 and the waste stuck in the mesh are continuously squeezed. The top plate 5345 is subjected to the squeezing force and squeezes the squeezing rod 5344, so that the squeezing rod 5344 slides inside the contact rod 5341, so that the squeezing rod 5344 drives the connecting rod 5347 to move downward, and at the same time, the other end of the connecting rod 5347 drives the scraper 53 48 slides in the moving groove 5343, so that when the scraper 5348 is squeezed by the top plate 5345 and the waste chips stuck in the mesh, the scraper 5348 can slide out of the moving groove 5343, so that when the top plate 5345 ejects the impurities, the scraper 5348 can adaptively adjust the size of the scraper 5348 sliding out of the moving groove 5343 according to the size of the squeezing force of the impurities stuck in the mesh on the top plate 5345, so that the scraper 5348 cleans and scratches the inner wall of the mesh, thereby preventing the scraper 5348 from contacting and scratching the inner wall of the mesh for a long time when the top plate 5345 ejects the impurities stuck in the mesh, thereby causing friction damage to the inner wall of the mesh, and when working for a long time, the inner wall of the mesh will expand, thereby reducing the service life of the filter plate 54;

[0050] When the exhaust gas generated during welding enters the collection box 51, the exhaust gas entering the collection box 51 is sucked into the filter housing 561 through the filter 563, and is discharged after being filtered through the filter layer 564. At the same time, the scraper assembly 568 generates suction through the filter 563, so that the scraper 5348 drives the fourth spring 567 to move toward the second connecting plate 565, so that the scraper assembly 568 cleans the inner wall of the filter housing 561, thereby preventing the exhaust gas from passing through the filter housing 561 for a long time and the impurities in the exhaust gas from adhering to the inner wall of the filter housing 561.

[0051] By providing a clearance groove 5682 on the circular plate 5681, the filter 563 is prevented from interfering with the normal passage of the exhaust gas when it is sucking the exhaust gas. At the same time, the suction force generated by the filter 563 allows the scratch plate 5683 to clean and scratch the inner wall of the filter housing 561, thereby preventing the exhaust gas from passing through the filter housing 561 for a long time. Impurities in the exhaust gas will adhere to the inner wall of the filter housing 561 and are difficult to fall off naturally.
