[0002] Steel structures are widely used in office buildings, shopping malls, factories, subways, hospitals and other scenarios, and bear the functions of air supply, air exhaust, smoke exhaust and air purification. When the traditional steel structure is welded, the two steel structures to be welded need to be repeatedly adjusted in the center, which will cause low work efficiency, and manual welding is required during welding, which is low in work effect and high in labor intensity of workers. It cannot effectively meet the welding operation of a large number of steel structures. With the improvement of welding requirements, a device capable of automatic welding has appeared. Although the traditional automatic welding device can effectively ensure the welding quality, the automatic welding device can only weld the weld of one position during welding.

When the bidirectional screw rod 64 rotates, the two moving plates 61 slide on the second slide rail 8 through the sliding blocks on the bottom of the two sides, so that the stability during movement is ensured, the coaxiality of the two steel structures 4 is ensured, and the offset is avoided, and the quality of butt welding is further ensured.

[0029] Further, when the bidirectional screw rod 64 rotates, the driving gear 65 at the end of the bidirectional screw rod 64 meshes with the first toothed plate 66, the first toothed plate 66 drives the driven gear 67 to rotate during movement, the driven gear 67 drives the deflection shaft 68 to swing the deflection seat 69, and the deflection seat 69 swings to offset the welding gun 5 to the edge position of the steel structure 4, so that effective welding between the two steel structures 4 is realized.

By adopting the above technical scheme, when the welds of the two steel structures 4 are not at the middle position of the tooling table 9 during welding, the first driving motor 30 drives the screw rod 31 to drive the adjusting table 32 to move horizontally, the slot formed in the adjusting table 32 effectively pushes the deflection seat 69 to slide along the deflection shaft 68, so that the welding gun 5 installed on the deflection seat 69 is moved to the weld position between the two steel structures 4.

[0030] In the embodiment, the side wall of one side of the moving plate 61 is fixedly installed with the second toothed plate 610; the second toothed plate 610 is installed with the protection assembly 7; the protection assembly 7 comprises a protection plate 70; the protection plate 70 is arranged in an arc shape; the bottom of the protection plate 70 is fixedly installed with a rotating rod 71; and the rotating rod 71 is movably installed with the side wall of the tooling table 9 through a bearing with a seat. The end of the rotating rod 71 away from the protection plate 70 is fixedly installed with a second bevel gear 75; the second bevel gear 75 is meshedly connected with a first bevel gear 74 at the top; the first bevel gear 74 is coaxially installed with a first gear 72 through a rotating shaft 73; the first gear 72 is meshedly connected with the second toothed plate 610; and the rotating shaft 73 is movably installed with the side wall of the tooling table 9 through a bearing with a seat. By adopting the above technical solution, when the two moving plates 61 move towards the middle, the second toothed plate 610 installed on the moving plate 61 meshes with the first gear 72, so that the first gear 72 drives the first bevel gear 74 to rotate through the rotating shaft 73.

[0031] In this embodiment, a plurality of connecting screw holes 618 are evenly provided on the inner side of the clamping plate 60, and a limiting rod 619 is installed inside the connecting screw hole 618. The limiting rod 619 and one end of the connecting screw hole 618 are provided with a threaded head, and the threaded head is fixedly connected to the inner side of the clamping plate 60 through the connecting screw hole 618. By adopting the above technical solution, the position of the connecting screw hole 618 is used to install the limiting rod 619 according to the thickness of the steel structure being processed, thereby limiting the two sides of the steel structure installed at that position. Furthermore, for cylindrical steel materials, the limiting rod 619 can be eliminated, and the arc-shaped structure of the clamping plate 60 itself can be used to limit the movement.

[0032] The working principle of this invention is as follows: When in use, the steel structure 4 is first placed on the upright plate 62 on the moving plate 61 by hoisting. During the placement process, as the steel structure 4 descends, the bottom of the steel structure 4 contacts the pressure plate 617, so that the pressure plate 617 drives the two connecting plates 616 to deflect downward through the rotating shaft. At the same time, the two connecting plates 616 drive the corresponding clamping plates 60 to move inward along the connecting rod 63, so as to clamp and fix the steel structure 4. In the above process, the position of the connecting screw hole 618 is used to limit the position of the limiting rod 619 according to the thickness of the steel structure being processed, thereby limiting the two sides of the steel structure installed at that position; Furthermore, for cylindrical steel materials, the limiting rod 619 can be eliminated, and the arc-shaped structure of the clamping plate 60 itself can be used to limit the movement. After the steel structure 4 is placed, the second drive motor 612 drives the driven sprocket 615 mounted on the bidirectional lead screw 64 to rotate via the active sprocket 613 and the chain 614. When the bidirectional lead screw 64 rotates, the bottom sides of the two moving plates 61 slide along the second slide rail 8 via the slider, ensuring stability during movement and ensuring the coaxiality of the two steel structures 4 to avoid misalignment, further ensuring the quality of the butt welding. When the bidirectional screw 64 rotates, the driving gear 65 at the end of the bidirectional screw 64 meshes with the first toothed plate 66, the first toothed plate 66 drives the driven gear 67 to rotate in the process of moving, the driven gear 67 drives the deflection shaft 68 to realize the swing of the deflection seat 69, when the deflection seat 69 swings, the welding gun 5 is deflected to the edge position of the steel structure 4, and effective welding between the two steel structures 4 is realized; When welding, when the welds of the two steel structures 4 are not in the middle position of the tooling table 9, the first driving motor 30 drives the screw 31 to drive the adjusting table 32 to move horizontally, and the deflection seat 69 is effectively pushed to slide along the deflection shaft 68 through the groove on the adjusting table 32, so that the welding gun 5 installed on the deflection seat 69 is moved to the weld position between the two steel structures 4; When the two moving plates 61 move to the middle, the second toothed plate 610 installed on the moving plate 61 meshes with the first gear 72, the first gear 72 drives the first bevel gear 74 to rotate through the rotating shaft 73, the first bevel gear 74 meshes with the second bevel gear 75, the second bevel gear 75 is fixedly installed at the end of the rotating rod 71, the protection plate 70 at the other end of the rotating rod 71 is realized to be turned up, the effect of protecting the sparks generated during welding is realized, the situation that the sparks splash is avoided, and the strong light generated during welding is shielded.
