Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing, and more specifically to a high-precision steel structure welding processing device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields.

[0003] Welding is an important connection method for steel structures. When welding steel structures, they need to be positioned by fixtures. The steel structure cannot be automatically flipped during welding. When flipping, the fixture needs to be loosened and the steel structure needs to be flipped. The operation is cumbersome and affects the efficiency of welding. In addition, general fixtures have poor versatility. They are convenient for positioning square and other angular steel structures during welding, but they are not stable enough for cylindrical steel structures, and docking deviation may occur, affecting the processing quality.
