Modular design method and structure of welding fixture for trial-manufacture sample vehicles

Abstract

The invention relates to the technical field of automobile manufacturing equipment, in particular to a modular design method and a modular design structure of a welding fixture for trial-manufacture sample vehicles, which solve the problems of incapability of recycling, long design and manufacturing period and high manufacturing cost of sample vehicle trial-manufacture fixture parts of automobiles in the prior art. The welding fixture comprises a base and a fixture unit arranged on the base; structural members with the same functions in the welding fixture for the trial-manufacture sample vehicles are formulated into standard or standard series parts in the process of design and development to form a fixture module series, so that the standard or standard series parts are recycled in the development of the welding fixture for new type trial-manufacture sample vehicles and the welding fixture for small-lot vehicles, and non-standard parts in the fixture are subjected to structural design; and the standard parts and the non-standard parts in the welding fixture for the trial-manufacture sample vehicles are matched to form novel and complete welding fixture equipment for the trial-manufacture sample vehicles. Through the modular design method and the modular design structure, the aims of shortening the design and manufacturing period, recycling general and standard parts and reducing manufacturing cost are fulfilled.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing equipment, in particular to a modular design method and structure of a prototype car welding fixture. Background technique [0002] The clamp in the automobile welding fixture, that is, the welding fixture, and the welding displacement mechanical equipment are collectively referred to as process equipment in the production of welding structures. The welding workpiece is clamped by the welding clamp to ensure the welding of the welding workpiece. precision and welding quality. According to the traditional design method, the welding jigs of prototype vehicles or small-batch models are usually designed and manufactured in the form of special welding jigs. This design method does not consider the reuse of fixture parts, and the design and production cycle is long and the production cost is high, which can no longer meet the development needs of the automotive industry. Shortening th...

Problems solved by technology

[0006] The purpose of the present invention is to provide a modular design method to solve the problems of non-reusable parts, long design and production cycle, and high production cost of the automobile prototype trial production jig parts in the prior art, which can overcome the problems of the previous car body welding jigs. The disadvantages of over-resistance and long development cycle, to achieve rapid design, manufacture and installation, reduce the cost of fixture development and production due to trial production or small-batch model changes, to shorten the development cycle of the modular design method of the prototype car welding fixture and its structure
