Assembly sequence planning and assembling simulation of stamping die tools

摘要

An appropriate oriented assembly product model should not only contain comprehensive and integral definition of each individual part but more importantly should also contain the definition of all the assembly relations between subassemblies and parts. First, the configuration information is collected and recorded in a configure file and attribute of relevant designed part solid models during stamping die tools design process. On the basis of configure file and CAD solid models, an assembly graph summarized the assembly relations inside of assembly is built. A stamping die tools product model is composed of all component part solid models, a configure file and an assembly graph. Afterwards, intelligent partition rules of subassemblies are presented. As a result of the partition, a whole assembly of stamping die tools is divided into several subassemblies and individual parts, and a hierarchical assembly tree is generated corresponding based on assembly graph. Assembly sequence planning can be generated by reasoning on the basis of configure file, assembly graph and hierarchical assembly tree. At last, an example is used to present the approach of assembly sequence planning and the simulating process of automatic assembling of stamping die tools.
