Description

[0001] This utility model relates to the field of welding equipment technology, specifically to a welding device for assembling arc-shaped H-beams. Background Technology

[0002] The assembly of curved H-beams involves on-site hoisting procedures and preparation steps. This includes assembling the various components of a large structure on flat ground before hoisting it, or transporting simpler components to the site and hoisting them into place. Once the three main sections of the H-beam are tack welded, the first assembly is complete. After the main weld seam is completed using submerged arc welding, the second assembly begins. During the welding process, the welding torch is an indispensable tool; however, existing welding torches have a narrow range of motion and produce poor welding results. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an arc-shaped H-beam assembly welding device that can move and rotate over a wide range and efficiently complete the welding work.

A radial moving rack is provided on the side of the radial moving guide rail. A mounting plate is provided on the radial moving guide rail, and a U-shaped groove is provided at the bottom of the mounting plate. The U-shaped groove is slidably connected to the radial moving guide rail. A radial moving motor is mounted on the mounting plate, and the radial moving motor is connected to a radial moving gear via a drive shaft. The radial moving gear is located at the bottom of the mounting plate and is connected to the radial moving guide rail. The rack and pinion mesh, and the mounting plate one is fixedly connected to the axial guide rail. The axial guide rail has an axially movable rack on its side. The axial guide rail has a second mounting plate, which is L-shaped. The bottom of the second mounting plate has a U-shaped sliding groove, which is slidably connected to the axial guide rail. The second mounting plate has an axial moving motor, which is connected to an axial moving gear through a drive shaft. The axial moving gear is located at the bottom of the second mounting plate and meshes with the axial moving rack. The side wall of the second mounting plate has a welding torch rotating motor, which is connected to the welding torch.

[0005] The beneficial effects of this utility model are: the welding torch used in this utility model can move freely in the axial and radial directions through the radial and axial moving guide rails, and the welding torch can rotate 360 ​​degrees through the welding torch rotation motor, thus achieving the purpose of welding without dead angles and efficiently completing the welding work.

[0007] Reference Figure 1The present invention specifically adopts the following embodiment: It includes a radial moving guide rail 4, an axial moving guide rail 7, a welding torch 9, and a welding torch rotary motor 8. A radial moving rack 6 is provided on the side of the radial moving guide rail 4. A mounting plate 12 is provided on the radial moving guide rail 4, and a U-shaped groove 13 is provided at the bottom of the mounting plate 12. The U-shaped groove 13 is slidably connected to the radial moving guide rail 4. A radial moving motor 3 is mounted on the mounting plate 12. The radial moving motor 3 is connected to a radial moving gear 5 via a drive shaft. The radial moving gear 5 is located at the bottom of the mounting plate 12 and meshes with the radial moving rack 6. A axial guide rail 7 is fixedly connected to the mounting plate 12. An axial moving rack is provided on the side of the axial guide rail 7. A mounting plate 2 11 is provided on the axial guide rail 7. The mounting plate 2 11 is L-shaped. A U-shaped slide groove 2 10 is provided at the bottom of the mounting plate 2 11. The U-shaped slide groove 2 10 is slidably connected to the axial guide rail 7. An axial moving motor 1 is provided on the mounting plate 2 11. The axial moving motor 1 is connected to the axial moving gear 2 through a drive shaft. The axial moving gear 2 is located at the bottom of the mounting plate 2 11. The axial moving gear 2 meshes with the axial moving rack. A welding gun rotary motor 8 is installed on the side wall of the mounting plate 2 11. The welding gun rotary motor 8 is connected to the welding gun 9.

[0008] When using this arc-shaped H-beam assembly welding device, the radial movement motor 3 is started. The radial movement motor 3 drives the connected radial movement gear 5 to rotate. The radial movement gear 5 meshes with the radial movement rack 6, thus the radial movement motor 3 can drive the entire mounting plate 12 to move radially. During the radial movement of the mounting plate 12, the U-shaped slide groove 13 is slidably connected to the radial movement guide rail 4, providing support and guidance for the entire mounting plate 12, preventing it from deviating from the track. The mounting plate 12 is indirectly connected to the welding torch 9 through the axial movement guide rail 7, etc., and thus... The welding torch 9 completes radial movement; the axial movement motor 1 is started, which drives the axial movement gear 2 connected to it to rotate. The axial movement gear 2 meshes with the axial movement rack, so the axial movement motor 1 can drive the entire mounting plate 11 to move axially. During the axial movement of the entire mounting plate 11, the U-shaped slide groove 10 is slidably connected to the axial movement guide rail 7, which plays a supporting and guiding role for the entire mounting plate 11, preventing the entire mounting plate 11 from deviating from the track. The mounting plate 11 is connected to the welding torch 9 through the welding torch rotation motor 8, and then the welding torch 9 completes axial movement.

[0009] During the radial or axial movement of the welding torch 9, the welding torch rotary motor 8 is started. The welding torch rotary motor 8 can drive the welding torch 9 to rotate 360 ​​degrees, so the welding torch 9 can perform welding work on both flat and circumferential surfaces.

[0010] In summary, this arc-shaped H-beam assembly and welding device is easy to use. The welding torch, through radial and axial movement guides, allows for free axial and radial movement. The welding torch rotation motor enables 360-degree rotation, achieving welding without dead angles and efficiently completing the welding work.
