A construction method and structure of a personalized welding tool for the side frame of a passenger car

Abstract

The invention discloses a method for building personalized welding tooling for the side wall frame of a passenger car, which includes the following specific steps: step 1: setting area blocks, step 2: designing and producing special sub-moulds, step 3: forming a tooling scheme database, Step 4: Personalized selection of tooling scheme, Step 5: Welding and building side frame tooling. At the same time, it also discloses a side frame structure of a passenger car produced by a construction method of a personalized welding tool for a side frame of a passenger car. The present invention adopts the method of regional block combination to split the overall tooling requirements into several small regional blocks. Compared with the overall large tooling, the sub-regional block tooling is not easy to deform and is conducive to the storage and storage of the tooling, reducing the site occupation. At the same time, the index The increasing number of combinations meets the multi-state requirements caused by personalized customization, improves the utilization rate of equipment, reduces the waste of resources caused by idle equipment, and improves the response capability of the production line.

Description

technical field [0001] The invention relates to the technical field of passenger car welding frock production, and more specifically relates to a construction method and structure of a passenger car side frame personalized welding frock. Background technique [0002] Buses are a typical order-driven production-oriented manufacturing industry. In the product life cycle, the sales link is put forward, that is, the product design is oriented to the individual needs of customers. Compared with passenger cars, personalized customization leads to more changes in the shape, structure, and configuration of bus products, but the processing capacity of production equipment cannot be expanded simultaneously and rapidly with product design. At present, most bus manufacturers still use traditional production methods. Advanced intelligent equipment such as industrial welding robots cannot be applied on a large scale.

Compared with passenger cars, personalized customization leads to more changes in the shape, structure, and configuration of bus products, but the processing capacity of production equipment cannot be expanded simultaneously and rapidly with product design

At present, most bus manufacturers still use traditional production methods. Advanced intelligent equipment such as industrial welding robots cannot be applied on a large scale. They can only be applied in a small range of parts and components. The overall intelligent level of production is low.

[0003] Taking the welding of the bus side frame as an example, at present, most manufacturers still use the method of integral mother tire + integral sub-mould for welding processing. This production mode has the following problems: 1. The tooling design and production cycle is long and the investment is large. 2. The tooling is complex. Low utilization rate, 3. The production site occupies a large area, and the mold change cycle is long. 4. Advanced intelligent equipment such as industrial welding robots cannot be used on a large scale, which seriously restricts the improvement of bus production efficiency and benefits. It is the key to urgent improvement bottleneck
