Description

Technical Field

[0001] The invention belongs to the technical field of ships, and in particular relates to an automatic welding machine bracket tool and a use method thereof. Background Art

[0002] In ship welding work, automatic welding has been widely used in the processing, segmentation, slipway and other stages. Automatic welding uses an automatic welding machine, which moves through a fixed track. Under the guidance of the program, the machine automatically operates to complete the welding of the weld. However, since the track adopts a straight section and lacks support, automatic welding can only be widely used in the processing stage. When environmental conditions do not allow, it is difficult to promote it on a large scale in the segmentation, slipway and other stages due to the lack of support conditions for the automatic welding machine track. Moreover, automatic welding can only guarantee the improvement of the efficiency of the processing and welding stage, and cannot guarantee the welding efficiency of the segmentation and slipway stages, which account for a relatively high proportion, and the promotion degree is poor.

[0003] Although automatic welding can achieve the welding of butt welds and fillet welds on flat panels and improve the welding speed and quality, it uses a fixed straight track to make the welder weld along the track. If there is no support for the track and the welder, automatic welding will not be able to proceed. This will greatly limit the promotion of automatic welding, and the overall efficiency and quality of shipbuilding will be difficult to improve. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an automatic welding machine bracket tooling with adjustable angle and a method of using the same, so that automatic welding can be widely used in most stages of shipbuilding, realizing the feasibility and convenience of welding in stages such as sections and slipways and even in narrow locations.

[0005] The object of the present invention is achieved through the following technical solutions: an automatic welding machine support tooling, comprising:

[0006] The support plate comprises an upper support plate and a lower support plate which are arranged in parallel, and through holes are opened at corresponding positions on one side of the upper support plate and the lower support plate.

[0042] The support plate includes four steel plates (a first support plate 3, a second upper support plate 4, a first lower support plate 6, and a second lower support plate 7), which respectively form two independent upper support plates and lower support plates. The upper short support plate (upper support plate) includes a folded square plate (the first upper support plate 3) and a square plate (the second upper support plate 4). The short side of the folded square plate is 100 mm long, 30 mm wide, and 10 mm thick. The long side is 150 mm long, 100 mm wide, and 10 mm thick. A hole is opened in the middle of the long side plate 30 mm away from the short side, with a hole diameter of 20 mm. A semi-cylindrical edge is opened on the right end of the long side plate with a diameter of 10 mm; a semi-cylindrical edge is opened on the left end of the other end square plate with a diameter of 10 mm.
