Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary devices, in particular to a portable right-angle welding auxiliary tool. Background Art

[0002] In the manufacturing and construction process, right-angle welding is a common method, but it is also prone to process problems such as fixing troubles, angle deviation, and welding misalignment. When used to assist in the right-angle welding of pipes and plates, right-angle welding operations are often required. The requirements for right-angle welding are relatively strict, because if the angle does not reach the required 90°, it may cause errors in the equipment and device structure, thus affecting its use. Traditional right-angle welding requires welders to rely on experience and manual skills to ensure the accuracy of the angle, which easily leads to instability in the welding results.

[0003] Mainly when welding at right angles, it is necessary to align the position and the weld joint so that the welded workpieces remain vertical. This process is very time-consuming and often results in errors and mistakes due to human factors. In addition, caution must be exercised during the welding process. The workpieces are often deformed by force and moved by heat, which affects the welding effect and is very unfavorable for right-angle welding.

[0004] In the prior art, the auxiliary tools for right-angle welding are basically triangular plate structures. For example, Chinese patent No. CN213196309U discloses a right-angle positioning assembly for precision welding tooling of a large square frame, including a first positioning member and a second positioning member, wherein the first positioning member and the second positioning member are connected to form a right angle; Chinese patent No. CN213615050U discloses a right-angle welding auxiliary device, including a frame, wherein the frame is composed of a frame A and a frame B, wherein the end of the frame A is connected to the frame B through a hinge, and the frame A and the frame B are both connected to a support frame; in the above schemes, two brackets are used. A structure similar to a right-angled triangle plate is formed between them, and two right-angled sides are used to perform right-angle welding on the workpiece to be fixed; however, since the right-angled sides cannot provide good support for the workpiece to be fixed, especially in a high-altitude environment, it is more inconvenient for the staff to adjust with both hands, and when welding, one hand is required to hold the welding tool and the other hand to support the auxiliary tool, which is extremely inconvenient to operate, and no space can be made between the docking workpieces to be fixed, and 360-degree welding cannot be achieved; if the two auxiliary pipes to be welded are short in length, the pipes are very likely to be displaced, and it is inconvenient to perform welding operations, which affects the quality and operational safety of right-angle welding in high-altitude or elevated working environments.
