Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to an assembly welding device for producing truck frames. Background Art

[0002] In automobile frame manufacturers, the welding workload for dump truck frames, such as cylinder mounts and flip mounts, is enormous. The welding cycle varies from 40 to 60 minutes per vehicle, depending on the model, while the cycle time for other processes along the entire production line is only 5 to 15 minutes per vehicle. These processes are typically shorter than welding, severely limiting the production capacity of frames. To increase production capacity, automobile factories often increase staff or equipment. However, the welders required for these increases are paid significantly more than those for ordinary workers, resulting in high labor costs. Furthermore, relying solely on human workers results in poor welding consistency and quality assurance, and can negatively impact the health of welders. Consequently, adding welding robots and their accompanying welding treads is a viable alternative to manual welding.

[0003] The existing welding device cannot weld truck frames of different specifications, and can only weld one side at a time, and needs to be re-clamped and fixed when welding the other side, which reduces work efficiency. For example, a Chinese patent discloses a "frame welding and assembly connection device", and its application number is: "CN202022011042.9", which includes: a bearing platform; at least two first connecting rods arranged on the bearing platform, at least one first connecting rod is provided with a first clamping member, and at least one first connecting rod is provided with a second clamping member.
