A lightweight orbital five-axis welding robot

Abstract

The invention discloses a lightweight rail-mounted five-axis welding robot which comprises an X-axis moving module, a Y-axis moving module and a Z-axis moving module. A movement output end of the Y-axis moving module is perpendicular to and fixedly connected with the X-axis moving module. The lightweight rail-mounted five-axis welding robot further comprises a first rotating module and a second rotating module. A height regulating seat is fixed at a movement output end of the X-axis moving module in the X-axis direction. The Z-axis moving module comprises a rail. A transmission rack is fixed on the rail in the Z-axis direction. The rail is adsorbed on the surface of a to-be-welded workpiece through magnetic bases. A Z-axis base is arranged above the rail. A Z-axis rotating output device is fixed on the Z-axis base. A transmission gear is fixed at a rotating output end of the Z-axis rotating output device. The transmission gear is meshed and matched with the transmission rack. The first rotating module comprises a first rotating shaft base fixed on the height regulating seat. A second rotating shaft base is rotationally connected onto the first rotating shaft base. The lightweight rail-mounted five-axis welding robot adopting the structure is small in size, light in weight, and can be positioned quickly, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of automatic welding equipment, in particular to a lightweight track-type automatic welding robot, which is suitable for on-site and high-altitude welding operations. Background technique [0002] Hull welding is an important part of shipbuilding. Ship welding technology has mainly experienced the process from manual welding, semi-manual and semi-automatic welding to automatic and intelligent welding. With the increasing requirements of the modern shipbuilding industry for ship quality, there are higher requirements for hull welding. Advanced ship automation welding technology plays an important role in improving ship construction efficiency, reducing manufacturing costs, and improving ship manufacturing quality. . [0003] At present, welding robots have been widely used in the field of welding. Traditional general-purpose welding robots have shown good results in various types of welds, even complex curve welds. H...

Problems solved by technology

However, for some steel structure welding that requires high-altitude operations, such as hull segmental closure welding, large-scale building steel structure welding, etc., traditional welding robots are difficult to adapt to on-site high-altitude operations due to their large size and inconvenient installation.

Chinese patent 201420012191.9 provides a profiling horizontal welding equipment, the horizontal welding equipment is installed in a portal frame, the volume is large, the installation is complicated, and the adaptability to high-altitude welding operations is insufficient; Chinese patent 201310434530.2 provides a complex trajectory All-position double-gun automatic welding robot, the welding robot has four degrees of freedom, compact structure, and can realize welding with complex trajectories, but because the welding torch can only rotate in one direction, the effect for multi-layer and multi-pass welding of large and thick plates Poor; Chinese patent 201410008280.0 provides a flexible track welding trolley, which has three moving axes and one rotating axis, and is equipped with flexible guide rails, suitable for flat and curved surface workpieces, but the installation form of the trolley makes it unsuitable for high-altitude horizontal welding. weld
