装配图参数化在模具设计中的应用

The application of parametric design of assembly drawings in die design

针对模具装配图设计，在零件图参数化的基础上，通过装配建模记录零件之间的装配关系，从而在装配模型实例化时自动产生相应零件图的变换矩阵；通过对装配尺寸、零件配合尺寸、零件尺寸及零件详细设计信息分级处理，来保证零件图和装配图的一致性以及在装配图设计的同时生成零件图。

In this paper,aimed at the die assembly drawings design,assembly relations are recorded by assembly modeling on the basis of parametric design of part drawings.The transforming matrixes of part drawings are automatically created when assembly model is instanced.Assembly dimension,part mating dimension,part dimensions and part design information are hierachically processed,so the consistency between assembly drawings and part drawings are guaranteed and assembly drawings and part drawings are created at the same time.
