Milling Fixture Under PDM Environment And Virtual Assembly Simulation

Aviation fixture design and information management level directly affects the aviation enterprise product quality, production schedules and costs. Combined with "large aircraft and aircraft engines for major equipment manufacturing information integrated application demonstration" projects, aviation fixture typical characteristics, how to achieve efficient use and management of the fixture information to improve the efficiency of the assembly fixture design and quality is particularly critical.In this paper, based on the traditional fixture design summary and analysis of the assembly process, the right management systems in aviation Teamcenter fixture design and data management in detail. Then based on the characteristics and classification milling fixtures, discusses the characteristics of the milling fixture assembly process, described the static milling fixture based NX5.0 basic theory of parametric design, completed the three-dimensional standard part library and typical fixture library, with examples interference Analysis. Then use the direction of demolition method demolition, demolition and step algorithm gives a theoretical basis for the optimal assembly sequence can be used to evaluate the results of assembly sequence. Finally leads Delmia method can be mounted on removable thinking and path planning principles, procedures and principles, complete path planning and simulation analysis.Through the typical milling jig example simulation, evaluation and analysis results show that design is feasible, making the fixture libraries and standard parts in the fixture design process efficient use, to achieve rapid design fixtures, data management, and assembly process simulation directly, naturally, visualization, has some engineering value.
