摘　　要：针对机床夹具标准件种类多,夹具设计依赖经验知识的特点,将实例推理技术和面向对象的参数化技术引入到机床夹具变型设计中,提出了一种基于实例推理的参数化变型设计技术。结合参数化特征建模方法、最近相邻算法和基于布局草图的自动装配等关键技术,开发了一套计算机辅助夹具设计系统,并应用实例验证了该系统的可行性和实用性。In view of a huge variety of standard part in machine tool fixture and the fixture design based on experi- ence knowledge, puts forward a kind of parametric variant design technology based on case based rea- soning which puts case based reasoning technology and the parameter technology of object oriented into the fixture variant design. Develops a computer aided fixture design system by combining the key tech- nology of parametric modeling, nearest neighbor algorithm and the automatic assembly technology based on sketch, and verifies the feasibility and practicability of the system by a case study.
