Description

Technical Field

[0001] The utility model relates to the field of cantilever walking welding robots, in particular to a 7-axis cantilever walking welding robot assembly structure. Background Art

[0002] The 7-axis cantilever robot walking axis, also called the robot walking axis or the seventh axis of the robot, is applicable to operations such as loading and unloading of machine tool workpieces, welding, assembly, spraying, inspection, casting, forging, heat treatment, metal cutting, handling, palletizing, etc. A robot walking system can achieve multi-station handling, and one robot can realize an automated processing process with multiple processing devices.

[0003] In recent years, with the development of industry and the progress of technology, people's requirements for welding quality have become higher and higher. Welding robots have the advantages of stable and improved welding quality, high automation level, and being suitable for mass production, and are increasingly widely used. Therefore, they have broad application prospects in the future. In container factories, it is often necessary to weld and repair some large and complex workpieces, mainly using equipment such as automatic cantilever arc welders and manual welding. However, the cantilever arc welding equipment can only perform straight-line operations on a single-direction axis. When welding more complex workpieces, the position of the welding equipment must be adjusted multiple times, and the workpieces also need to be repeatedly adjusted for the operation stations. The labor intensity is high and the operation efficiency is low, which is no longer suitable for welding operations of larger workpieces. At the same time, during the welding movement process, the X-axis walking slide structure is prone to problems of discontinuous movement. Summary of the Utility Model
