Problems solved by technology

The above assembly and welding processing methods are not easy to guarantee welding quality, poor process reliability, and easy deformation
In addition, due to the cover of the bottom plate during the overall welding, the welding space is narrow, which is easy to cause welding defects. Especially, double-sided welding cannot be performed on the joints between the reinforcement ribs, the frame and the longitudinal beams, which affects the welding strength. Medium-strength failure produces cracks, and at the same time, a large amount of welding thermal stress gathers on one side, making the overall deformation resistance poor

Abstract

The invention discloses an engineering packing box bottom board set assembling and welding method. The engineering packing box bottom board set assembling and welding method comprises the first step of combination of a frame, the second step of installation of longitudinal beams, the third step of arrangement of reinforcing bars, the fourth step of arrangement of a bottom board, and the fifth step of installation of accessories. The conventional assembly sequence of a packing box bottom board set is changed, and therefore the purposes of creating the space, improving the welding operation environment and then improving the welding quality are achieved. The more effective welding process method is provided, the welding intensity is further ensured, partial concentration of welding thermal stress is effectively prevented, welding deformation is reduced, and the deformation resistance of the whole is improved.

Description

technical field [0001] The invention relates to the field of engineering truck manufacturing, in particular to a method for assembling and welding an engineering cargo box bottom plate assembly. Background technique [0002] The bottom plate assembly of the cargo box of the engineering truck is composed of four parts: the frame, the bottom plate, the longitudinal beam, the reinforcing rib and the accessories. At present, the general assembly and welding method of the cargo box floor assembly of engineering trucks is: assemble the frame → place the bottom plate → place the longitudinal beam → arrange the reinforcing rib → spot welding at the welding point → conventional overall welding → install the accessories. The above-mentioned assembly and welding processing methods are not easy to guarantee the welding quality, poor process reliability, and easy to deform. In addition, due to the cover of the bottom plate during the overall welding, the welding space is narrow, which i...
