Description

Technical Field

[0001] This utility model relates to the field of welding, specifically a detachable welding operation frame. Background Technology

[0002] Steel structure welding manufacturing (i.e., welded structure production) begins with preparations for welding production. This includes structural feasibility review, process plan and specification design, process qualification, preparation of process documents (including quota preparation) and quality assurance documents, ordering of raw and auxiliary materials, and purchasing or designing and manufacturing assembly-welding equipment. The actual welding manufacturing process begins with material warehousing, including material re-inspection and warehousing, material preparation and processing, assembly-welding, post-weld heat treatment, quality inspection, and finished product acceptance. This process also includes rework, finishing, and painting. Finally, qualified products are put into storage. During steel structure welding, to improve welding quality, it is usually necessary to ensure the stability of the steel structure during welding.

[0003] Common steel structures generally include steel frames, angle irons, steel pipes, and steel plates. Due to the different shapes of various components, the functional requirements for welding workbenches are more complex. Typical welding workbenches include...

[0004] 1) CN220838754U discloses a welding operating frame, which includes pipe fittings, connectors, and a lifting mechanism. The lifting mechanism is equipped with a centering mechanism. Two pipe fittings are connected via the connectors, and the centering mechanism clamps the two ends of the two pipe fittings. In this application: the two pipe fittings are connected together using the connectors, thus fixing the welding position. Then, the centering mechanism clamps the two pipe fittings, allowing them to rotate, so that the posture does not need to be changed during welding, which is beneficial for the uniformity of rotational welding.

[0005] 2) A steel plate positioning and welding device disclosed in CN219403008U includes: a positioning assembly, comprising an operating table, a telescopic rod, a push plate, three L-shaped fixing plates, and five positioning wheels. The horizontal section of the L-shaped fixing plate is located on the top of the operating table, and the outer side of the longitudinal section is provided with two protruding plates. One end of the telescopic rod is horizontally located on the top of the operating table via a support plate, and the other end is connected to the push plate. Two protruding plates are provided at each end of the push plate. The upper and lower ends of the five positioning wheels are respectively rotatably connected between the corresponding two protruding plates for positioning the steel plate; a pair of steel pipe clamping and transfer assemblies are symmetrically located on the top of the operating table for clamping the steel pipe and transferring it to the groove at the end of the steel plate; and a pair of welding assemblies are symmetrically located on the top of the operating table for automatically and accurately welding the steel pipe to the steel plate.
