[0003] Steel fire doors need to be welded during the production process. Due to their specifications and quality, the welding angle is extremely difficult to adjust during the welding process, which affects the processing efficiency. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a welding tool for the production of steel fire doors, which solves the problem that steel fire doors need to be welded during the production process. Due to their specifications and quality, the welding angle is extremely difficult to adjust during the welding process, affecting the processing efficiency.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a welding tool for steel fire door production, comprising an operating box, a servo motor and a plurality of welders, wherein the driving end of the servo motor penetrates the side wall of the operating box and extends to the inside thereof and is fixedly connected to a mounting rod, and the end of the mounting rod away from the driving end of the servo motor is rotatably connected to the inner wall of the operating box through a bearing, and a plurality of adjusting rollers are fixedly sleeved on the outer surface of the mounting rod, and the plurality of adjusting rollers are arranged in a linear array, and the outer surfaces of the plurality of adjusting rollers are surrounded by adjusting grooves, and the plurality of adjusting grooves are arranged along the mounting rod. The mounting rod is extended in the direction of the mounting rod, and a driving rod is arranged under the plurality of adjusting rollers, and the tops of the plurality of driving rods are respectively slidably engaged in the inside of the adjusting grooves above them, and the bottoms of the plurality of driving rods are fixedly connected with driving tooth plates, and a positioning mechanism is arranged under the plurality of adjusting rollers, and the positioning mechanism includes an adjusting gear, and the bottoms of the plurality of adjusting gears are fixedly connected with connecting shafts, and the outer surfaces of the connecting shafts are sleeved with limiting cylinders, and the limiting cylinders are fixedly connected with the inner wall of the operating box through short shafts, and the bottoms of the plurality of connecting shafts are fixedly connected with strong electromagnetic adsorption plates.

[0006] Preferably, the shape of the plurality of limiting cylinders is trumpet-shaped, the inner side walls of the plurality of limiting cylinders are fixedly connected to hydraulic rods near the top, and the output ends of the plurality of hydraulic rods are in contact with the outer side wall of the connecting shaft.

[0007] Preferably, a limit frame is slidably sleeved on the outer surface of each of the plurality of driving rods, and the limit frame is fixedly connected to the inner wall of the operating box via a fixed shaft, and a straight groove parallel to the mounting rod is opened inside each of the plurality of limit frames.

[0008] Working principle: When in use, the main frame is positioned by a strong electromagnetic adsorption plate, and the welder is started to cooperate with welding. When the welding angle needs to be changed, the servo motor is started, and the driving end of the servo motor drives the mounting rod to rotate. Since the adjustment groove on the outer surface of the adjusting roller extends in the horizontal direction, and the driving rod with one end slidingly engaged with it is limited by a straight groove parallel to the mounting rod inside the limit frame, when the adjusting roller rotates, the driving rod will drive the driving gear plate to move back and forth in the horizontal direction. At this time, the teeth on the positive side wall of the driving gear plate can drive the adjusting gear to rotate with the adjusting gear through the action between the adjusting gear, thereby changing the welding angle, which is convenient for actual processing. When the welding is completed, the steel door structure is not taken out first. At this time, the hydraulic rod contracts, and the servo motor keeps in motion. The driving gear plate drives the adjusting gear to perform intermittent forward and reverse rotation movements, and during the rotation, it itself shakes. The irregular rotation can throw off the welding slag adhering to the surface of the steel structure, realize simple cleaning, and facilitate subsequent processing.

[0009] (III) Beneficial effects The present invention provides a welding tool for producing steel fire doors. It has the following beneficial effects: 1. For the welding tooling used in the production of steel fire doors, when it is necessary to change the welding angle, start the servo motor, and the driving end of the servo motor drives the mounting rod to rotate. When the adjusting roller rotates, the driving rod will drive the driving gear plate to move back and forth in the horizontal direction. At this time, the teeth on the positive side wall of the driving gear plate can drive the adjusting gear to rotate with the adjusting gear through the action between the adjusting gears, thereby changing the welding angle, which is convenient for actual processing.

[0010] 2. The welding tooling used in the production of steel fire doors, after welding is completed, the steel door structure is not taken out first. At this time, the hydraulic rod contracts, and the servo motor keeps moving. The drive gear plate drives the adjustment gear to make intermittent forward and reverse rotation movements. During the rotation, it shakes itself. The irregular rotation can throw off the welding slag adhering to the surface of the steel structure, realize simple cleaning, and facilitate subsequent processing. BRIEF DESCRIPTION OF THE DRAWINGS
