工装设计参数化系统的设计与实现

Design and Implementation of Parameterization System for Engineering Tooling Design

目的参数化设计作为一种新兴的CAD设计方法,改进工艺装备设计能提高产品零件的加工精度和设计效率。方法针对工装产品零件,进行CAD二次开发,设计独立于CAD的功能菜单及参数化设计系统,通过结构参数输入,函数调用,启动CAD,从而实现产品零件参数化自动绘图的功能。在此基础上建立了基于C/S模式的具有上传、下载、在线查询等功能的网络工装参数化设计系统。结果实现产品全生命周期的计算机辅助设计与制造,对工装设计中特征性强、成系列化的工装任务进行参数化设计,具有提高技术准备手段、提高工装设计的准确性、节约工作时间、缩短工期等显著特点,提高了工装产品的设计效率。结论缩短了工装产品的开发周期,降低了企业的生产成本。

Objective To increase the machining accuracy and design efficiency of product parts by improving the design of process equipment by parametric design,a new CAD design method.Methods Aimed at the parts of tooling products,the secondary development of CAD was carried out,and the function menu and parametric design system independent of CAD were designed.By input of structural parameters,calling for functions and CAD starting,the function of parameterized automatic drawing of product parts was realized.On this basis,a network tooling parametric design system based on C/S mode with functions of uploading,downloading and online query was established.Results It realized the computer-aided design and manufacture of the whole life cycle of the product,and carried on the parametric design of the characteristic and serialized tooling tasks in the tooling design.It had the remarkable characteristics of improving the technical preparation means,improving the accuracy of tooling design,saving working time and shortening the construction period.The design efficiency of tooling products was improved.Conclusion Parametric design greatly shortens the development cycle of tooling products and reduces the production cost of enterprises.
