Semitrailer grillage-shaped beam welding tooling and welding process thereof

Abstract

The invention belongs to the technical field of aluminum alloy welding and relates to a semitrailer grillage-shaped beam welding tooling and a welding process for the semitrailer grillage-shaped beamwelding tooling. The semitrailer grillage-shaped beam welding tooling comprises a base and a main body frame rotatably installed on the base, wherein the left side and the right side of the main bodyframe are provided with three fixed end position-limiting blocks and moving end position-limiting blocks correspondingly, the outer sides of the fixed end position-limiting blocks and the moving end position-limiting blocks are fixedly provided with corresponding two sets of traction pin plate longitudinal beam compressing devices and a set of front end locking horizontal beam compressing devicescorrespondingly, the part, between the front end locking horizontal beam compressing devices, of the main body frame is evenly and fixedly provided with a plurality of front end locking horizontal beam connection angle part position-limiting grooves, and the part, between the traction pin plate longitudinal beam compressing devices, of the main body frame is evenly and fixedly provided with a plurality of traction pin plate position-limiting grooves used for clamping traction pin plate workpieces. By means of the welding tooling, the welding position is conveniently and efficiently adjusted toeliminate influence of the narrow and small space on welding operations, and by means of the position-limiting blocks and the compressing devices, the group matching accuracy is guaranteed to controlwelding deformation in the welding process.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy welding, and relates to a semi-trailer well-shaped beam welding tool and a welding process thereof. Background technique [0002] The installation and welding process of the original well-shaped girder assembly is as follows: first, the traction pin plate beam is welded and connected with the two longitudinal beams with bolts; Corner fittings and well-shaped beam assembly are attached figure 1 shown. The process first installs the welding of the traction pin plate beam, in order to avoid welding deformation of the traction pin plate beam due to welding deformation The matching bolt holes of the joint and the longitudinal beam are not concentric, which makes the installation of the well-shaped beam assembly difficult or impossible. [0003] However, with this process, when welding the rear section of the traction pin pole longitudinal beam and the front section of the traction pin plate l...
