Embodiment Construction

[0023] The embodiment of the present invention will be described in detail below by taking the welded part of the front beam of the sub-frame of an integral self-loading and unloading vehicle as an example in conjunction with the accompanying drawings.

[0024] The assembly welding device provided by the invention is used for positioning and pressing each part of the welded sub-frame front beam weldment, so as to facilitate accurate welding. Although the weldment of the front beam of the subframe shown in this embodiment is the weldment of the front beam of the subframe of an integral self-loading and unloading vehicle, it is not limited to this, and it can also be the weldment of the front beam of the subframe of other types of vehicles. pieces.

[0025] Such as Figure 1-4 As shown, the assembly welding device provided by the present invention includes: a workbench 1, a bearing 4 for supporting the workbench arranged on both sides of the workbench, rigidly fixed on the work...

Abstract

A welding assembly device, including a workbench, a support for supporting the workbench, a positioning assembly fixed on the workbench for positioning and a pressing assembly for pressing, with rotating shafts and The reinforcement plate is provided with a shaft sleeve on the upper part of the support, a support horizontal plate is provided on the side of the support, a support vertical plate is provided between the support horizontal plate and the shaft sleeve, the support vertical plate is perpendicular to the support horizontal plate, and the shaft is installed In the sleeve, the first hole is processed on the reinforcement plate, the second hole is processed on the support horizontal plate, and the third hole is processed on the support vertical plate. The worktable rotates with the rotation of the shaft, and the positioning pin is inserted into the first hole and the second hole. Insert the middle or positioning pins into the first hole and the third hole to fix the workbench. The welding assembly device of the present invention can effectively control welding deformation, ensure the assembly size accuracy and shape position accuracy of the subframe front beam welded parts, improve product quality, and meet the interchange requirements of product consistency.

Description

technical field [0001] The invention relates to a welding assembly device, more specifically, to a welding assembly welding device for the front beam of the auxiliary frame of an integral self-loading and unloading vehicle. Background technique [0002] At present, in the process of welding and assembling the front beam of the whole self-loading and unloading sub-frame, only the bottom plate, C-shaped groove plate, cylinder seat of the front beam, axle sleeve, reinforcement plate, bent plate, Ribs, fixed seats, inner reinforcement plates, side plates and other parts are positioned, assembled, and spot welded to weld the welds in the horizontal position, and then removed from the platform to weld the welds in the vertical position. Because there is no anti-deformation measure when welding the weld in the vertical position, the welding deformation exceeds the standard, and the verticality and parallelism of the front beam cylinder seat shaft hole exceed the standard tolerance,...
