[0013] like Figure 1 As shown, a prefabricated building steel structure welding device includes two groups of symmetrically arranged placement parts, each group of placement parts is provided with a plurality of longitudinally arranged placement racks 1, a welding mechanism is provided between the two groups of placement parts, and the welding mechanism includes a welding base 2, a track 3 is provided on the top of the welding base 2, a moving seat 4 is traveled on the track 3, a lifting seat 5 is installed on the top of the moving seat 4, a slide 7 is provided on the top of the lifting seat 5, two mounting seats 8 are slidably provided on the slide 7, a slide groove 18 is provided at the bottom of the mounting seat 8, the slide groove 18 cooperates with the slide 7, both ends of the mounting seat 8 extend in the width direction of the slide 7, and the mounting seat A welding gun 9 is installed on the side of 8, and the welding gun 9 is connected to a welding machine 10. The welding machine 10 is installed on the top of the movable seat 4 and is located on the side of the lifting seat 5. Specifically, when welding the I-beam 20, the bottom plate and the vertical plate are first spot-welded at equal intervals to connect the bottom plate and the vertical plate together, and then the connected bottom plate and vertical plate are placed on the placement rack, and the position of the welding gun 9 on the mounting seat 8 and the height of the lifting seat 5 are adjusted to make the position of the welding gun 9 correspond to the place where welding is required. When welding, the movable seat 4 travels on the track, that is, moves along the length direction of the workpiece to achieve welding.

[0014] The placement rack includes a horizontal bracket 11, the top of the horizontal bracket 11 is fixedly connected to a vertical bracket 12, the side of the vertical bracket 12 is fixedly connected to an oblique bracket 13, the top of the horizontal bracket 11 is fixedly connected to an oblique bracket 2 14, and a 90-degree angle is formed between the oblique bracket 13 and the oblique bracket 2 14; specifically, the connecting parts of the bottom plate and the vertical plate are placed at a 90-degree angle on the oblique bracket 13 and the oblique bracket 2 14, so that the welding gun 9 can be located at the welding position of the bottom plate and the vertical plate when it is in a vertical state, thereby ensuring an effective weld melting depth and improving the welding quality.

[0015] A vertically arranged hydraulic cylinder 15 is installed between the moving seat 4 and the lifting seat 5, the fixed end of the hydraulic cylinder 15 is fixedly connected to the top of the moving seat 4, and the free end of the hydraulic cylinder 15 is fixedly connected to the bottom of the lifting seat 5; specifically, when the hydraulic cylinder 15 is started, the free end of the hydraulic cylinder 15 is lifted and lowered to drive the lifting seat 5 to move up and down, so that the welding gun 9 moves up and down to adjust the distance between it and the welded part.

After the position is determined, the fixing bolts 19 are tightened, and the bottom surface of the fixing bolts 19 is tightly pressed against the top of the lifting seat 5 to fix the mounting seat 8, thereby realizing the adjustment and fixation of the position of the welding gun 9.

[0018] Baffles 6 are fixedly connected to the top of the lifting seat 5 and at both ends of the slideway 7; specifically, the baffles 6 limit the movement of the mounting seat 8.

[0019] The specific working process is: place the I-beam 20 with the vertical plate and the bottom plate already spot-welded together on the placement racks 1 on both sides, adjust the positions of the two welding guns 9 so that the welding guns 9 are located at the position of the weld on the workpiece, and the lifting seat 5 adjusts the position between the welding gun 9 and the weld. The moving seat 4 is driven by the driving motor 17 to move, driving the welding gun 9 to weld the workpiece along the length direction of the workpiece, and then weld the other side after welding; after the vertical plate and the bottom plate of the I-beam are welded, the vertical plate and the top plate of the I-beam 20 are welded by the same working method.
