Problems solved by technology

The disadvantage of this method is that the labor intensity is high, and the welded frame side beams will inevitably produce deflection deformation, so that the deflection is difficult to control, that is, the produced frame side beams are difficult to be straight, so the quality is difficult to control

Embodiment 1

[0016] As shown in Figure 1-2, the automatic assembly and welding device for frame side beams in this embodiment includes: two adjustment seats 1 oppositely arranged for placing the frame side beams, and six supports arranged between the two adjustment seats 1 3 (in other embodiments, it can be 2-5, or more), the hydraulic clamp 4 and the welding trolley 8 for fixing the side beam c of the frame, which are arranged on the support 3; the upper end faces of the two adjustment seats 1 Relatively inclined; the upper end surface of each support 3 is lower than the lowest point of the upper end surfaces of the two adjustment seats 1 .

[0017] The two adjustment seats 1 include: a base 1-1, a roller 1-5 arranged at the bottom of the base 1-1, a front strut 1-2 and a rear strut 1-3 oppositely arranged on the base 1-1, Splicing is arranged on the support plate 1-4 of front strut 1-2 and rear strut 1-3 upper end, and the upper end face of support plate 1-4 is the upper end face of adju...

Abstract

The present invention relates to an automatic welding device for vehicle frame side beam comprising two adjusting bases equipped face to face for placing frame side beam, at least two support saddles equipped between the two adjusting bases, a hydraulic clamp equipped on the support saddle and a welding car supported by two sides of the frame side beam; the upper ends faces of the two adjusting bases are relatively tilted; the upper end faces of the support saddles are lower than the lowest point of the upper end face of the adjusting base. The upper ends faces of the two adjusting bases are relatively tilted and the upper end faces of the support saddles are lower than the lowest point of the upper end face of the adjusting base, i.e. the two adjusting bases and every support saddle form a curved surface; welding is implemented on the curved surface, i.e. a camber is preset before welding; when the frame side beam is taken down after welding, the frame side beam begins to deflect and deform inversely, i.e. the preset camber is balanced out by the deflection and deformation to control the frame side beam camber in the permitted range which ensures the production quality; in addition, the welding car is adopted for the implementation of the automatic welding; in this way, the welding labor intensity is small.

Description

technical field [0001] The invention relates to an automatic welding device for side beams of a vehicle frame. Background technique [0002] The existing train carriages are more than ten meters long and two meters high. Among them, see figure 2 , the frame side beam c of the compartment consists of a cross-section more than ten meters long The shaped channel steel a is welded with the bottom plate b of the corresponding length. The welding method in the prior art is: use clamps to fix the channel steel and the bottom plate of the side beam of the vehicle frame, and then weld synchronously on both sides of the channel steel to form a vehicle frame side beam with a cross-section similar to a square. The disadvantage of this method is that the labor intensity is high, and the welded vehicle frame side beams will inevitably produce deflection deformation, so that the deflection is difficult to control, that is, the produced vehicle frame side beams are difficult to be straig...
