Novel passenger car body tensioning skin lifting device

Abstract

The invention relates to a novel passenger car body tensioning skin lifting device. The novel passenger car body tensioning skin lifting device comprises a main bearing cross beam (1), a hanging bracket cross beam (3) and a hanging hook (4) used for moving by a operating traveling crane and a plurality of electromagnetic chucks (2) used for attracting a car body skin (5); the hanging bracket crossbeam (3) is fixed to the top of the main bearing cross beam (1); the hanging hook (4) is fixed in the central position of the top of the hanging bracket cross beam (3); a hook hole of the hanging hook (4) is arranged in the operating traveling crane; the plurality of electromagnetic chucks (2) are uniformly distributed on the side wall of the main bearing cross beam (1); the plurality of electromagnetic chucks (2) are controlled by the same electromagnetic chuck controller circuit; and the electromagnetic chuck controller circuit comprises a rectifying circuit, a control circuit and a protection circuit. Compared with the prior art, the novel passenger car body tensioning skin lifting device has the advantages of simple operation, cost saving, labor saving, occupied space saving, accuratepositioning and the like.

Description

Technical field[0001]The invention relates to the technical field of passenger car body skin installation, in particular to a new type of passenger car body tension skin hoisting device.Background technique[0002]With the current domestic bus technology becoming more and more mature, the welding workshops of various OEMs have installed large-scale skin automatic stretching devices, which enables semi-automatic welding of the body skin welding station, which is more advanced than the previous welding process. Convenient and more precise. But at present, the automatic stretching equipment for body stretching and skinning is expensive and covers a large area. For some small and medium bus companies, the equipment costs to be borne are very high, occupy a large area of ​​the production line, and require professional technical personnel to operate the equipment, and the construction cost and the manpower and capital required to be invested are high. Therefore, many companies still use the...

Problems solved by technology

With this operation method, a large amount of workpiece adjustment time is required when welding the body skin, and more labor is required to easily cause employee injuries. The positioning process can account for 40%-50% of the entire processing process, and the clamping positioning is prone to obvious problems. error, high scrap rate, very low efficiency

Due to the large shape and high height of the body skin, it is about 2-3 meters above the ground. During the human lifting process of the skin, it is easy to cause deformation of the skin, forming creases, and irreversible quality defects on the smoothness of the skin surface. , and it is prone to a series of problems such as inaccurate positioning, poor welding quality, and loose skin, so it is urgent to design and develop a simple, easy-to-use, and low-cost body skin lifting device
