Semi-automatic welding equipment for T-shaped plates with rounded corners

Abstract

The invention discloses semi-automatic welding equipment for T-shaped plates with rounded corners. The semi-automatic welding equipment comprises a base, a first clamping mechanism, a second clampingmechanism, a transmission mechanism and a swinging mechanism. The swinging mechanism is arranged on the base. The transmission mechanism is arranged on one side of the swinging mechanism and is matched with the first clamping mechanism and the second clamping mechanism. The first clamping mechanism and the second clamping mechanism are symmetrically arranged at the top of the swinging mechanism and are used for clamping the T-shaped plates with the rounded corners correspondingly. The semi-automatic welding equipment further comprises a first welding mechanism and a second welding mechanism. The first welding mechanism and the second welding mechanism are arranged on the first clamping mechanism and the second clamping mechanism correspondingly and are used for conducting resistance welding operation on the T-shaped plates with the rounded corners. According to the semi-automatic welding equipment for the T-shaped plates with the rounded corners, stable clamping and automatic horizontal moving of the T-shaped plates with the rounded corners and adjusting of a clamping angle of a welding gun are achieved, the welding problems of the T-shaped plates with the rounded corners such as ahull rib plate frame structure and a door arch crossbeam are solved, the limitation of CO2 trolley welding flat and straight T-shaped plates is broken, and the welding efficiency and quality and thesemi-automatic level are improved.

Description

technical field [0001] The invention relates to the technical field of ship welding equipment, in particular to a semi-automatic welding equipment for T-shaped plates with rounded corners. Background technique [0002] CO 2 Gas shielded welding is one of the common welding methods in the production process of enterprises. It is easy to operate and suitable for automatic welding and all-round welding. It has poor wind resistance during welding and is often used indoors. When using a conventional welding power source, it is impossible for the molten metal at the end of the wire to form a balanced axial free transition. Usually, it is necessary to use short circuit and droplet constriction to burst. Compared with the degree of freedom of MIG welding, there is more spatter. Due to the low price of the shielding gas used, the welding seam is well formed when the short-circuit transition is adopted, and the high-quality welded joint without internal defects can be obtained by usi...

Problems solved by technology

Among them, shipbuilding companies usually use manual spot welding or CO 2 The trolley semi-automatically welds the T-shaped bar. After welding, it needs to be polished for a long time. Manual work will inevitably cause problems such as large deformation and poor quality. This requires pyrotechnic correction of the weldment. ,low efficiency

In addition, when encountering irregular and complex T-section welding problems, such as welding hull rib plate frame structures, beams with door arches, and vertical girder toe end joint structures, even if CO 2 The semi-automatic welding of the trolley can only weld the regular and straight structures, and the on-site workers must spend a lot of energy to successfully complete the entire welding process
