Problems solved by technology

[0003] The orthopedics of welded parts is the biggest waste in the production process of welded products, which increases the manufacturing cycle of welded products. In the past, the repair time of each group of frames was about 3 hours (two people). According to the production capacity plan of 12 vehicles / day, every day is wasted 72 hours; and due to mechanical and flame adjustments, the base metal of the welded product will collapse, the risk of weld cracks and tissue hardening will affect the safety of the product

Abstract

The invention relates to the technical field of welding deformation control and discloses a framework welding deformation control method and a framework welding tool. The method comprises the following steps: performing structural simulation analysis on a framework to divide the framework into a plurality of welding compositions according to modules and determining the welding sequence of welded joints among all the welding compositions; and based on the welding sequence, welding the welded joints among all the welding compositions. The framework welding tool comprises a clamp body, and a middle support, a torsion-proof device, a cross beam tight-pressing device and a side beam tight-pressing device which are arranged on the clamp body, so that mounting and fixation of the framework are facilitated. Repairing of the framework can be avoided, the manufacturing period is greatly shortened and efficiency and quality are enhanced.

Description

technical field [0001] The invention relates to the technical field of welding deformation control, in particular to a frame welding deformation control method and frame welding tooling. Background technique [0002] Due to the uneven heating and cooling during the welding process, the welding deformation is inevitable in the welding structure. The welding deformation usually needs to be corrected by machinery, flame, or a combination of the two, so as to obtain a qualified size. [0003] The orthopedics of welded parts is the biggest waste in the production process of welded products, which increases the manufacturing cycle of welded products. In the past, the repair time of each group of frames was about 3 hours (two people). According to the production capacity plan of 12 vehicles / day, every day is wasted 72 hours; and due to mechanical and flame adjustments, the base metal of the welded product will collapse, the risk of weld cracks and tissue hardening will affect the s...
