A car body hanger

Abstract

An automobile body hanger disclosed in an embodiment of the present invention includes a hanging clamping mechanism. The hanging clamping mechanism includes: a connecting beam; at least two hanging fixtures on both sides arranged on the connecting beam; The two hanging legs can move towards and away from each other, and at most one hanging fixture on both sides is a fixed hanging fixture, and the other hanging fixtures on both sides are sliding hanging fixtures that can move along the connecting beam; The rear hanging frock is movably arranged on the connecting beam, and the rear hanging frock is used for hanging the top position of the rear door of the vehicle body. The present invention adapts to the car bodies with and without side windows by designing two different hanging tooling combinations, and then solves the problem of flexibility of the hanger for all car body-in-white welding off-line, painting on-line, painting off-line and final assembly on-line The problem is that the bodies of various models can share one kind of spreader, and there is no need to switch spreaders when switching models, and there is no need for redundant spreaders to temporarily use the workshop site for nothing.

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
