Abstract

The invention discloses an automatic welding machine and a welding method for steel structural parts. The automatic welding machine for the steel structural parts comprises a portal frame which spans on a steel structural part to be welded and can longitudinally move along the steel structural part, and a welding arm which is arranged in the portal frame; and the welding arm comprises a mechanical arm, a mounting plate fixedly arranged at the upper end of the mechanical arm, a transverse moving device arranged at the top of the portal frame and used for driving the mounting plate to transversely move, a connecting plate fixedly arranged at the lower end of the mechanical arm, a welding gun fixedly arranged on the connecting plate and a three-dimensional imaging device arranged beside the welding gun and fixedly connected with the connecting plate. According to the automatic welding machine for the steel structural parts provided by the invention, manual welding of the steel structural parts is replaced, normal welding is guaranteed, and the welding efficiency is improved. A turnover device enables the steel structural parts to be turned over automatically, manual participation is not needed, the efficiency is further improved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of welding of steel structural parts, in particular to an automatic welding machine and welding method for steel structural parts. Background technique [0002] With the rapid development of the economy, my country's infrastructure construction is developing faster and faster. In infrastructure construction, a large number of steel structural parts are used. Columns and beams are one of the most basic and important steel structural members. These steel structural parts are relatively simple in structure, with many welds, and most of the welds are linear. At present, these steel structural parts are welded manually, which is time-consuming, labor-intensive, and inefficient. Not only is the welding cost high, but it is also difficult to ensure the welding quality. These steel structures need to be turned over during welding so that all sides of the steel structures are welded. Since the weight of the steel...
