Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding, in particular to an automatic welding torch swing track converter. Background Art

[0002] In the construction of combined automatic welding, especially in mountainous and hilly areas and during tie-in welding, weld joints with angles of 15° to 45° are always encountered. The work efficiency and quality of welding these weld joints are related to the overall construction period and overall benefits.

[0003] During the automatic welding process, the welding head travels along a track fixed on the pipeline. In order to obtain a corresponding weld width, the welding torch needs to swing horizontally. When welding a weld joint in the horizontal position, the welding torch swings horizontally, and a symmetric weld formation can be obtained on the left and right. However, when welding a 15° to 45° weld joint, the welding torch does not swing horizontally, resulting in the molten iron in the molten pool falling under its own weight, and the weld formation shows a phenomenon of one side being higher than the other side, that is, the weld formation is not symmetric. At the same time, intermittent or dot-shaped unfused defects may appear inside the weld bead, and edge biting may occur outside, reducing the welding quality. To solve these problems of formation and defects, the previous method was to adjust parameters such as the swing width and welding speed. However, the adjustment of parameters increased the number of welding layers and passes, prolonged the welding time, and reduced the work efficiency.

[0004] Therefore, it is necessary to manufacture a welding torch inclination adjuster to change the position and angle of the welding torch with the adjuster, so that the welding torch swings horizontally, a symmetric and relatively wide weld bead can be obtained, the construction efficiency can be improved, and at the same time, unfused defects are eliminated.

[0005] The patent document with the application number CN202120933130.6 discloses a special welding torch connection component for fillet welds of an automatic welding machine, including a bottom plate, side wing plates and angle adjustment pieces. The bottom plate is provided with bottom plate bolt holes at the bottom, which are matched with the bolt holes of the welding torch support; symmetric side wing plates are fixedly connected to both sides of the bottom plate, and side wing plate bolt holes are respectively opened in the upper parts of the side wing plates for fixing the angle adjustment pieces. There is 1 angle adjustment piece fixing threaded hole on each side, which is matched with the bolt hole of the side wing plate, and a first hexagon socket head cap screw is built in for fastening connection; 2 welding torch fixture fixing threaded holes are arranged at the top of the angle adjustment piece, which are matched with the bolt holes of the welding torch fixture, and a second hexagon socket head cap screw is built in for fastening connection. During use, first connect the side wing plates and the angle adjustment pieces with 2 sets of hexagon socket head cap screws and set them aside; then remove the welding torch fixture of the Kemppi X3-500 type automatic welding machine, and install and fix the connection component at this position; install and fix the welding torch fixture on the top of the angle adjustment piece, and the assembly of the connection component is completed. By loosening and tightening the bolts on both wings and rotating the angle adjustment piece, the angle adjustment of the welding torch can be achieved. However, when this connection component is applied to the Xiong Gu A-305 pipeline automatic welding machine, when the welding torch needs to be disassembled for maintenance, it is necessary to disassemble the first hexagon socket head cap screws on both side wing plates. Since the space between the first hexagon socket head cap screw close to the pipeline and the pipeline is limited, the first hexagon socket head cap screw close to the pipeline is not convenient to disassemble, which makes it inconvenient to disassemble and maintain the welding torch. At the same time, since the first hexagon socket head cap screw close to the pipeline is not convenient to rotate, when the angle between the bottom plate and the angle adjustment piece needs to be locked after adjustment, it is not convenient to tighten the first hexagon socket head cap screw close to the pipeline. Utility Model Content

[0006] The technical problem to be solved by the present utility model lies in an automatic welding torch swing trajectory converter that is convenient for disassembling and assembling the welding torch, facilitating the maintenance of the welding torch, capable of adapting to different welding torches, and facilitating positioning after the angle of the welding torch is adjusted.

[0007] In order to achieve the above object, the technical solution provided by the present utility model is:

Screws pass through the through holes and are threadedly connected to the gun head motor. A fixed sleeve is fixed on the fixing plate. The axial direction of the fixed sleeve is parallel to the length direction of the fixing plate. A rotating sleeve is rotatably arranged on the fixing plate on one side of the fixed sleeve. The fixed sleeve is away from the pipeline to be welded relative to the rotating sleeve. A rotating plate is fixed on the rotating sleeve.

It can be applied to the installation of various gun heads.

[0012] 2. When disassembling the gun head, rotate the bolt. After the bolt is separated from the rotating sleeve, the gun head can be separated from the automatic welding machine, which is convenient for disassembling the gun head for maintenance and is relatively convenient for installing the gun head.
