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

The invention relates to an assembly welding device which comprises a workbench, supports for bracing the workbench, locating components which are fixed on the workbench and used for locating, and compaction components used for compacting, wherein rotating shafts and reinforced plates are arranged on the two sides of the workbench; shaft sleeves are arranged at the upper parts of the supports; bracing transverse plates are arranged on the side surfaces of the supports; bracing vertical plates are arranged between the bracing transverse plates and the shaft sleeves, and perpendicular to the bracing transverse plates; the rotating shafts are mounted in the shaft sleeves; first holes are formed in the reinforced plates; second holes are formed in the bracing transverse plates; third holes are formed in the bracing vertical plates; the workbench rotates with rotating of the rotating shafts; and locating pins are inserted into the first holes and the second holes, or inserted into the first holes and the third holes, so that the workbench is fixed. The assembly welding device can control welding deformation effectively, so that the assembly size accuracy and the shape position accuracy of a subframe front transverse beam welding piece are ensured; the product quality is improved; and an exchange requirement of the consistency of a product is met.

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,...
