A trailer frame assembly assembly welding system

Abstract

The invention discloses a trailer frame assembly assembling and welding system which comprises supporting frames, overturning shafts, a workpiece supporting component and an electric control device. The workpiece supporting component comprises a workpiece supporting plate of a flat plate structure. The two ends of the workpiece supporting plate are fixedly connected with the other ends of the overturning shafts. The upper surface of the workpiece supporting plate is provided with multiple pressing devices and positioning devices. Each pressing device comprises a supporting base, a telescopic control mechanism and a pressing head. Each positioning device comprises a cross beam positioning mechanism, a transverse beam positioning mechanism and an edge beam positioning device. The position, corresponding to a weld joint in the bottom face of a trailer frame assembly, on the workpiece supporting plate is further provided with a hollow groove type structure. The electric control device comprises an industrial control computer, a power source loop and an overturning control loop. According to the trailer frame assembly assembling and welding system, overall rapid positioning, assembling and welding of a trailer can be completed, the assembling and welding efficiency is high, overturning is convenient, and the potential safety hazard that hoisting and overturning are likely to cause looseness can be avoided.

Description

technical field [0001] The invention relates to an assembling and welding system, in particular to an assembling and welding system suitable for trailer frame components, and belongs to the technical field of trailers. Background technique [0002] A trailer refers to a vehicle that is towed by a car and has no power drive itself. It can usually be a car train composed of a tractor (truck or tractor, forklift, etc.) and one or more trailers. The car train belongs to the category of cars. The use of automobile and train transportation is the most effective and simple important means to improve economic benefits. It has the advantages of rapidity, maneuverability, flexibility and safety, and can conveniently realize section transportation. [0003] Trailers are divided into full trailers and semi-trailers according to the connection method between the trailer and the tractor. The full trailer is pulled by the tractor and its entire mass is borne by itself; [0004] A trailer ...

AI Technical Summary

Problems solved by technology

[0005] Due to the long front and rear dimensions of the overall workpiece of the frame assembly, large volume, many welds, and high welding quality requirements for the welds, the assembly and welding of the trailer frame assembly is usually carried out step by step at present, that is, first according to the parts. Assemble and weld separately, then integrate and assemble each part, and finally perform integrated welding. In the process of integrating, assembling and welding, in order to prevent welding deformation, it usually needs to be turned over multiple times with the whole body. This traditional assembling and welding method usually cannot be realized in The entire weld seam in the front and rear direction, so the strength of the weld seam is relatively low; and if the welding deformation occurs during the welding process of each component in the step-by-step assembly welding method, it is easy to produce cumulative errors in the integrated welding process, which is easy to cause the frame The shape and position errors such as the overall tilt adjustment of the components; in addition, the large frame volume makes it difficult to turn over, which not only easily causes the lifting to fall apart, but also poses safety hazards
