Plate positioning part of a trailer frame assembly assembly welding system

Abstract

The invention discloses panel positioning components of a trailer frame assembly splicing welding system. The number of the panel positioning components is multiple, and the multiple panel positioning components are arranged on the upper surface of a workpiece supporting plate (31), and the panel positioning components comprise compression devices (32) and positioning devices (33); each compression device comprises a supporting base fixedly installed on the workpiece supporting plate, a stretchable control mechanism installed on the supporting base and a pressing head installed on the stretchable control mechanism, the compression directions of each compression device at least comprise the horizontal direction and the vertical direction, the compression devices are symmetrically arranged with respect to a positioned panel, and the pressing heads are oppositely arranged; and each positioning device comprises a large beam positioning mechanism, a transverse beam positioning mechanism and an edge beam positioning mechanism. By means of the panel positioning components of the trailer frame assembly splicing welding system, overall and quick splicing and welding of a trailer can be achieved, and the splicing and welding efficiency is high.

Description

technical field [0001] The invention relates to a plate positioning part, in particular to a plate positioning part suitable for an assembly and welding system of a trailer frame assembly, 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; ...

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. Assembling and welding separately, and then integrating and assembling each part, and finally performing integrated welding. In order to prevent welding deformation during the integrated assembling and welding process, it usually needs to be turned over multiple times with the whole body. Usually a manual control device with self-locking function is used. The operator is not only labor-intensive, but also the manual control device with self-locking function is easy to wear, and the clamping force is likely to be insufficient due to long-term operation due to wear, and accurate positioning cannot be guaranteed.
