Description

Technical Field

[0001] This utility model relates to the field of welding fixtures, specifically to a welding device for processing parts of a tunnel boring machine. Background Technology

[0002] Tunnel boring machines (TBMs), as major engineering equipment integrating mechanics, electrical systems, and hydraulics, are widely used in the excavation of subway tunnels, highway tunnels, and urban pipeline tunnels. Their manufacturing process involves the welding of numerous large steel structural components. These components are typically bulky, complex in structure, and require extremely high welding precision and quality. TBM components come in various sizes and specifications, but traditional welding fixtures are mostly designed for single dimensions and lack adjustability. The welding process requires alternating work on both sides of the workpiece; traditional methods rely on hoisting equipment or manual turning, which is time-consuming and poses safety hazards.
