Description

Technical Field

[0001] The present invention relates to the technical field of welding, and in particular to a steel structure welding positioning device. Background Art

[0002] Shielded metal arc welding is the most widely used welding method in industrial production. The metal to be welded is used as one electrode, and the welding rod is used as the other electrode. When the two electrodes approach, an arc is generated. The heat generated by the arc discharge (commonly known as arc burning) melts the welding rod and the workpiece with each other and forms a weld after condensation, thereby obtaining a firm joint during the welding process.

[0003] Through retrieval, Chinese Patent Publication No. CN118492826B discloses a building steel structure welding positioning device, which includes a first positioning component and a second positioning component. The first positioning component includes a first clamping part and a first rotating part. The first clamping part is used to clamp the first ferroalloy. The first rotating part includes a first arc plate and a first arc track that are perpendicular to each other. The first clamping part can slide along the first arc track. The second positioning component includes a second clamping part and a second rotating part. The second clamping part is used to clamp the second ferroalloy. The second rotating part includes a second arc plate and a second arc track that are perpendicular to each other. The second clamping part can slide along the second arc track. The second arc plate is slidably matched with the first arc plate to adjust the included angle between the first positioning component and the second positioning component. This building steel structure welding positioning device has good versatility, convenient operation, and improves the welding positioning efficiency.

[0004] Before automatic arc welding, it is necessary to clamp and fix the steel structure to be welded to ensure the accuracy of the welding position. Since the steel structure profiles have large structural width and thickness, gaps need to be left during clamping and docking so that the solder can fill the inside of the gaps during welding, making the welding more firm. Existing welding positioning jigs cannot ensure the accurate position and angle of two non-contact materials, and various positioning blocks are required for positioning when the steel structure welding is placed on the welding platform, which will block the welding position. Therefore, a steel structure welding positioning device is proposed. Summary of the Invention

By setting the slidable movable clamping sleeve, the welded steel structure can be accurately adjusted in angle after being clamped, achieving the effect of accurately positioning various welding situations according to requirements, and solving the problem that the shapes and angles of welded steel structures are different and cannot meet the welding requirements of various angles.
