Middle combined clamping tool for welding front assemblies of inner plates of left and right side walls of automobile

Abstract

The invention relates to a middle combined clamping tool for welding front assemblies of inner plates of left and right side walls of an automobile. The middle combined clamping tool for welding frontassemblies of inner plates of left and right side walls of the automobile comprises a middle supporting device, a side plate supporting device, a middle accessory positioning and pressing device anda right accessory positioning and pressing device; and the middle accessory positioning and pressing device and the right accessory positioning and pressing device are successively distributed on theright side of the middle supporting device. The middle complicated structures of the front assemblies of the inner plates of the left and right side walls of the automobile are designed specially, bythe tool, all components involved in the middle can be clamped and positioned, relative precision of the various components is ensured, the space utilization rate is high, and the production and manufacturing cost is reduced. In addition, automated welding treatment of an external welding robot is facilitated, the production efficiency and the quality of products are greatly improved, the degree of automation is high, and batched production and machining are realized favorably.

Description

technical field [0001] The invention relates to the technical field of production and processing of automobile parts, in particular to a central combined clamping tool for welding the front assembly of left and right side inner panels of automobiles. Background technique [0002] Most of the components on automobile products are spliced ​​by many small parts and then connected by welding. The precision requirement is higher. In particular, the structure of the middle part of the front assembly of the left and right side wall inner panels of the car is relatively complicated, including the splicing of the tail part and the main body and the welding after the positioning of several ear seats. The traditional method mostly adopts multi-process and multi-station positioning, clamping, and welding fixation. Although this method solves the problem of forming the middle part of the front assembly of the left and right side panels of such a large-sized car, it does not Due to the ...

Problems solved by technology

The traditional method mostly adopts multi-process and multi-station positioning, clamping, welding and fixing. Although this method solves the problem of forming the middle part of the front part of the left and right side panels of the large-sized car, it does not Due to the method of multi-process, multi-station, and multiple clamping and positioning, the overall accuracy after processing is difficult to guarantee. Often, the inspection fails after the overall welding is formed, and it needs to be returned to the factory for repair, which seriously affects the efficiency of production and processing.
