在应用机器人进行智能化装配中,如何让计算机理解机械图纸是一项重要课题。本文基于对机械装配图的分析和理解,结合相关知识,提出一种装配关系模型DG—ARM,并在此基础上得出零件装配次序的推理算法。最后用一实例说明相应DG-ARM的建立和装配次序的推导结果。 In the application of robots for intelligent assembly, how to make computers understand the mechanical drawings is an important issue. Based on the analysis and comprehension of the mechanical assembly drawing, combined with related knowledge, this paper presents an assembly relationship model DG-ARM, and deduces the inference algorithm of the parts assembly sequence. Finally, an example is given to illustrate the derivation of the corresponding DG-ARM setup and assembly sequence.
