摘要
三维装配工艺以动画的形式,辅以音频和文字,直观生动地表达装配过程和装配要求,工人容易理解且不易产生歧义,对提高装配质量和提高效率非常有效。文章研究了如何有效利用三维模型中的信息,快速高质量地完成三维装配工艺。首先通过对MBD技术的研究,建立了基于MBD的装配信息模型;其次提出了“拆卸定义装配”的方式来规划装配活动,将拆卸活动归纳为螺旋运动、直线运动等多类拆卸活动,通过对拆卸活动的顺序、拆卸活动的属性做“逆操作”来定义装配活动;最后采用基于MBD的装配信息模型和“拆卸定义装配”的模式研发了三维装配工艺规划系统,此系统通过在制造企业的应用,验证了方案的可行性和合理性,缩短装配工艺设计周期,提高装配效率和质量。
The 3D assembly process in the form of animation,audio and text,expresses the assembly process and assembly requirements vividly.As a result,workers could easily understand and improve the quality of assembly,and the information is not ambiguous.This paper studies focuses on how to use the information in the 3D model to complete the 3D assembly process effectively.Firstly,basing on the studies about MBD technologies,it establishes the MBD-based assembly information model.Secondly,it advances“disassembly definition assembly”,to plan assembly activities.The disassembly activities are summarized into spiral movement,linear motion and other types of disassembly activities,through the order of disassembly activities,the attributes of disassembly activities to do“reverse operation”to define the assembly activities.Finally,based on the MBD-based assembly information model and the“disassembly definition assembly”mode,the 3D assembly process planning system is developed to verify the feasibility and rationality of the scheme through the application of manufacturing enterprises,shorten the assembly process design cycle,and improve assembly′s efficiency and quality.
