Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a shield machine component processing and welding device. Background Art

[0002] As a major engineering machinery equipment, the shield machine has been widely used in the excavation construction of subway tunnels, highway tunnels and urban pipe network tunnels. The shield machine is a high-tech product that integrates mechanics, electricity and hydraulics. Its manufacturing process is also relatively complicated, especially the main steel structure parts of the shield machine, which are large in size, volume and weight, and are often manufactured by welding. Due to the large welding workload and the uneven technical level of welding workers, the product welding production cycle is long, the production efficiency is low, and the welding quality is difficult to be stably guaranteed.

[0003] The document with the existing authorization announcement number CN203316925U discloses an automatic welding device for steel structure parts of a shield machine, including a welding robot, a workpiece fixture, a gantry, and an automatic welding control system. It adopts robot welding technology, has high welding efficiency, reliable welding quality, greatly saves labor costs, and also has the advantages of easy manufacturing and installation.

[0004] However, this solution still has some shortcomings. The front and back sides of the main steel structure components of the shield machine need to be welded, but the workpiece fixture used in this solution does not have an automatic flipping function. Therefore, a crane or other large lifting equipment is needed to flip the components over and re-fix them, which takes a lot of time and manpower. Summary of the invention
