Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a welding equipment for heavy truck frame production. Background Technique

[0002] As is well known, the heavy truck frame is the main structural component of heavy commercial vehicles, usually welded by high-strength steel, and is used to support and carry the weight of the whole vehicle and various power transmission and suspension systems. It not only determines the structural strength and stability of the vehicle, but also affects the durability and safety of the vehicle. Usually, welding equipment is required in the production process of heavy truck frames. The welding equipment is used to weld various metal parts and components together to form a frame with a solid overall structure.

[0003] However, the traditional welding equipment for heavy truck frame production usually adopts fixed welding points. When different parts of the frame need to be welded, it may be necessary to rearrange and adjust the position of the workstation or reconfigure the equipment, which not only increases the adjustment cost of the production line, but also may lead to a decrease in production efficiency. Therefore, technical improvement is urgently needed. Content of the Utility Model
