High-speed Train Welding Flexible Tooling System Design

High-speed railway is a major high-tech achievement of the world's railway, High-speed railway is the world of modern safe and reliable transportation. Domestic high-speed access to rapid development of railway construction. The face of the rapid development of high-speed railway industry, Improve the production efficiency of high-speed train to become a pressing matter. High-speed train to achieve digital manufacturing and Assembly of flexible welding technology manufacturing automation is becoming a bottleneck in the train. Coupled with its long life, high reliability, rapid development of needs, requirements and welding assembly of digital technology, automation and flexible. Market demand for new models of continuous high-speed rail is becoming an important feature of manufacturing changes. In order to enable enterprises to short-term, low cost fast converting different types of vehicles, to achieve a single tooling equipment to complete the multi-body models and models of train with different profile group function. In this paper, the idea for the product family, the use of flexible modular design of high-speed train design tooling for welding of the system.Development that is suitable for welding a high-speed train the same body with different profiles: including the roof, side walls, chassis, and the dome flat assembly and welding, and welding for different models of the same kind of flexibility profiles Automatic tooling systems.Papers on high-speed train body flexible welding fixture system of the overall program design, detailed analysis of flexible tooling system works and to complete the structural design of fixture system and three-dimensional model;At the same time the structure of the fixture system finite element software was checked and optimization;Profiles of high-speed train flexible welding fixture computer aided management system development and implementation were studied.
