Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a ship maintenance welding robot. Background Art

[0002] During the process of ship manufacturing and maintenance, there is a large amount of welding work, such as the splicing of decks, the splicing of outer plates, and the welding of aggregates under the decks. The decks of ships are generally welded together by several steel plates. Since the decks are basically flat, the existing splicing of decks is completed by automatic welding robots. A welding robot is an industrial robot engaged in welding, including cutting and spraying. According to the definition of an industrial robot belonging to a standard welding robot by the International Organization for Standardization, an industrial robot is a multi-purpose, reprogrammable automatic control manipulator with three or more programmable axes, and is used in the field of industrial automation.

[0003] The existing welding robot can adjust the welding angle of the robotic arm during welding work, but the overall welding direction of the robot is not easy to adjust, resulting in the robot being unable to cope with workpieces of different shapes and sizes, limiting its application in the welding of complex structural parts, reducing production efficiency. For workpieces that require multi-directional welding, the robot may require additional flipping devices or manual intervention, increasing the complexity and cost of operation. At the same time, when the robot malfunctions or needs adjustment, the lack of direction adjustment ability may make the diagnosis and solution of problems more difficult.
