Automobile body sling

Abstract

The embodiment of the invention discloses an automobile body sling. The automobile body sling comprises a hanging clamping mechanism. The hanging clamping mechanism comprises a connecting beam, at least two two-side hanging tools arranged on the connecting beam and a rear hanging tool movably arranged on the connecting beam along the connecting beam and used for hanging the rear door top position of an automobile body. Two hanging legs of each two-side hanging tool can move to get close to each other or get away from each other. At most one two-side hanging tool is a fixed hanging tool, and the other two-side hanging tools are sliding type hanging tools capable of moving along the connecting beam. Two different hanging tool combinations are designed so that the automobile body sling can adapt to automobile bodies with side windows and without side windows, and accordingly the problem about sling flexibility of all automobile types of white body welding lower lines, coating upper lines, coating lower lines and final assembly upper lines is solved; and automobile bodies of various automobile types can share one sling, sling switchover is not needed during automobile type switchover, and unnecessary slings temporally occupying the site of a workshop in vain do not exist.

Description

technical field [0001] The invention relates to the technical field of automobile tooling, and more specifically relates to an automobile body hanger. Background technique [0002] In the automobile manufacturing plant, the spreader is a very common tooling equipment. The shape and structure of the spreader depends on the structure of the product. The structure of the product is different, and the shape and structure of the spreader are also different. These spreaders have one thing in common - the degree of flexibility is not high. [0003] The flexibility of the spreader in the prior art is not high, and it cannot adapt to the models of different platforms or the models with large differences on the same platform. The difference between the car bodies of different platforms is mainly the difference in length and width; The difference is mainly passenger cars (such as figure 1 Shown) with side windows, logistics vehicles (such as figure 2 shown) without side windows. ...

AI Technical Summary

Problems solved by technology

[0006] Although the spreader of the prior art can utilize the cylinder to realize automation, there are many limitations

First, there is no flexibility, and various problems will occur during use. For example, if the width of the vehicle body becomes smaller or larger, the spreader needs to be changed; if the position of the vehicle body is slightly deviated, the spreader will not be hooked properly

Second, because the cylinder must be driven by compressed air, there is no ready-made air source in areas with less compressed air such as the paint shop

Third, when the spreader needs to walk, the length of the cylinder must be greater than the walking distance. The longer the walking distance, the more difficult it is to deal with the release and retraction of the cylinder
