摘　　要：标准件在工装设计中起着提高设计效率、降低设计成本的重要作用,针对目前已有标准件库构建方法中存在的标准件检索效率、实例化效率和装配效率低下的问题,提出了面向快速响应设计的工装标准件库构建方法。通过分析各类工装标准件的尺寸参数类型和装配约束关系,构建了标准件参数化模板,实现标准件的快速实例化及快速装配,根据工装标准件的管理方法,设计了基于属性相似度加权的工装标准件检索算法,实现标准件的快速检索,最终开发了面向快速响应设计的工装标准件库,并以某型航空发动机机匣零件铣削外型面夹具设计为例,验证了所提方法的正确性和有效性。Standard parts play an important role in improving design efficiency and reducing design cost in tooling design.In view of the problems of retrieval efficiency,instantiation efficiency and assembly efficiency in the existing standard parts library construction methods,a standard parts library construction method based on fast response design is proposed.By analyzing the size parameter types and assembly constraints of various types of tooling standard parts,the parameterized template of standard parts is constructed to realize the rapid instantiation and rapid assembly of standard parts.According to the management method of tooling standard parts,a tooling standard part retrieval algorithm based on attribute similarity weighting is designed to realize the fast search.At last,tooling standard parts library for fast response design is developed.The method is proved by taking fixture design for milling profile of certain type of aero engine for example.
