[0024] like Figure 1-3 As shown, the utility model provides a steel structure welding bracket, which includes a base plate 1 as an installation base.

[0025] In this embodiment, the bracket includes a steel structure fixing mechanism 3 installed on the upper part of the base 1 for fixing the steel structure 2. The steel structure fixing mechanism 3 includes a first threaded column 31, a first guide shaft 32, a connecting plate 33, a connecting rod 34 and a clamp 35. The bottom end of the first threaded column 31 is rotatably connected to the upper surface of the base 1. The bottom end of the first guide shaft 32 is fixedly connected to the upper surface of the base 1. One end of the connecting plate 33 is movably sleeved with the first guide shaft 32, and the other end is threadedly engaged with the first threaded column 31. One end of the connecting rod 34 is fixedly connected to the connecting plate 33, and the other end is fixedly connected to the clamp 35. The clamp 35 is an existing commonly used structure and is not described here. As mentioned above, when the first threaded column 31 is rotated, the first threaded column 31 can drive it to move up and down to adapt to steel structures 2 of different lengths by threading with one of the connecting plates 33.

[0026] Furthermore, the bracket also includes a rotating mechanism 4 for allowing the steel structure 2 to rotate horizontally. The rotating mechanism 4 includes a turntable 41, a gear ring 42, a gear 43, a gear shaft 44 and a magnet 45. The base plate 1 is provided with a groove for the turntable 41 to rotate horizontally, and the turntable 41 is used to support the steel structure 2. The gear ring 42 is fixedly sleeved on the top of the turntable 41, and the gear 43 is fixedly sleeved with a gear shaft 44, and the bottom end of the gear shaft 44 is rotatably connected to the base plate 1. The gear 43 is meshed with the gear ring 42, so when the gear shaft 44 is rotated, the turntable 41 can be driven to rotate together through the meshing between the gear 43 and the gear ring 42. In this embodiment, the friction between the steel structure 2 and the turntable 41 can be used to make the steel structure 2 rotate with the turntable 41, and a magnet 45 can also be installed on the turntable 41 as shown in the figure, and the steel structure 2 can be horizontally rotated with the turntable 41 through the magnetic adsorption of the magnet 45 to the steel structure 2.

[0027] Furthermore, the bracket also includes a welding gun positioning mechanism 5 installed on the upper part of the base plate 1 for welding the rotating steel structure 2. The welding gun positioning mechanism 5 includes a second guide shaft 51, a welding gun placement bar 52, a fixing bar 53 and a second threaded column 54. A pair of second guide shafts 51 are provided, and the bottom ends of the two second guide shafts 51 are fixedly connected to the upper surface of the base plate 1, and the top ends thereof are fixedly connected to the two ends of the fixing bar 53 respectively. The two ends of the welding gun placement bar 52 are movably connected to the two second guide shafts 51 respectively, and the welding gun placement bar 52 is threadedly engaged with the second threaded column 54. The upper surface of the welding gun placement bar 52 is provided with a welding gun head placement groove 521. When welding, the head of the welding gun is placed in the welding gun head placement groove 521 facing the steel structure 2. The top end of the second threaded column 54 is rotatably connected to the fixing bar 53, and the bottom end of the second threaded column 54 is rotatably connected to the upper surface of the base plate 1. Therefore, when the second threaded column 54 is rotated, the second threaded column 54 drives the welding gun placement bar 52 to adjust its height up and down through the threaded engagement between the second threaded column 54 and the welding gun placement bar 52 to adapt to welding seams of different heights.

[0028] The working principle of this embodiment is as follows: place the two steel structures 2 to be welded in the upper and lower clamps 35 as shown in the figure, rotate the nut on the clamp 35 to adjust the clamping force of the clamp 35 on the steel structure 2, and ensure that the steel structure 2 can rotate therein without tilting. Then rotate the second threaded column 54, and the second threaded column 54 drives the welding gun placement bar 52 to move up and down through the threaded engagement between the second threaded column 54 and the welding gun placement bar 52, so that the welding gun head placement groove 521 and the joint of the two steel structures 2 are kept at the same height. When the welding gun head is placed in the welding gun head placement groove 521, the joint of the two steel structures 2 can be welded. During welding, hold the gear shaft 44 and rotate the gear 43. The gear 43 drives the turntable 41 to rotate through the meshing between the gear ring 42. The turntable 41 drives the steel structure 2 to rotate through the friction between it and the steel structure 2. In this embodiment, a magnet 45 is added, and the magnetic adsorption of the steel structure 2 by the magnet 45 can further ensure that the steel structure 2 can follow the rotation. When the steel structure 2 rotates, different positions of the joints can all face the welding gun, and the welded seam remains horizontal, forming a smooth welding surface effect.

[0029] In summary, through the design of the welding gun positioning mechanism 5 and the horizontal rotation of the steel structure 2 through the rotating mechanism 4, the butt joint can be rotated while keeping the welding gun position unchanged, so as to weld a flush weld, and the welding gun positioning mechanism 5 has a height adjustment function to accommodate steel structures 2 of different lengths; the steel structure fixing mechanism 3 can allow two steel structures 2 to be vertically butt-jointed, and also has a height adjustment function to accommodate steel structures 2 of different lengths.

[0030] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
