General assembly fixture for body welding assembly line

Abstract

The invention provides a car body welding assembly line assembly fixture which comprises a fixed base plate, a moving base plate provided with a side body fixture, a fixed limiting block, a movable limiting block and a switching stop block. The moving base plate is matched with the fixed base plate in a sliding mode and driven by a first air cylinder to slide on the fixed base plate, the fixed limiting block is fixed to the fixed base plate, the movable limiting block is fixed to the moving base plate, and when the first air cylinder pulls back the moving base plate, a second air cylinder drives the switching stop block to be located between the movable limiting block and the fixed limiting block, or drives the switching stop block to be separated from the position between the movable limiting block and the fixed limiting block. The car body welding assembly line assembly fixture can be generally used by vehicle models with the same side body but the different floor width, and thus production flexibility is achieved, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a general assembly fixture for a body welding line. Background technique [0002] For some models, such as truck products, the update speed of models is much slower than that of sedan products. However, due to various configuration requirements, or due to different export regulations in different regions, multiple models can be derived from one model platform. These models mainly change in the width direction of the body floor, but the left and right side panel assemblies are common. [0003] Generally speaking, according to the shape of the side wall assembly, it is necessary to set up supporting fixtures, so as to realize the final welding of the side wall assembly and the body floor on the body welding line. In the prior art, since the assembly jigs of the body welding line are fixed on the workstations, even the models with common left and right side panels cannot be welded on one pr...

AI Technical Summary

Problems solved by technology

In the prior art, since the assembly jigs of the body welding line are fixed on the workstations, even the models with common left and right side panels cannot be welded on one production line due to the different floor widths, that is to say, Different products derived from one platform cannot be produced on the same production line, which results in excessive investment in production costs

In the prior art, there are many devices capable of switching clamps, but the switching of these clamps is only to adapt to different side wall assembly shapes, or to add more clamping points to the clamp to adapt to more side wall assembly shapes, but Neither can accommodate the same side panel assembly but different floor widths
