航空发动机量检具是航空发动机工装的一类,对应不同型号发动机的同一种零件,该零件的工装结构尺寸随零件的系列尺寸相应变化。本文在分析了发动机工装设计过程的基础上,对工装进行了数字化建模,并将系列尺寸的工装模型参数化、模板化,开发出了工装设计系统,使设计人员在工装设计中缩短了设计周期,降低了设计成本,并成功应用在某航空发动机企业的工装设计部门中。 Aero-engine gage is a type of aeroengine tooling, which corresponds to the same kind of parts of different engine models. The size of the part structure varies with the series of parts. Based on the analysis of engine tooling design process, the tooling is digitized and modeled, and the tooling design model is developed. The tooling design system has been developed so that designers can shorten the design of tooling design Cycle, reducing design costs, and successfully applied in a certain part of aeroengine tooling design department.
