基于关键特性的数字化容差分配技术分析

Analysis of Digital Tolerance Allocation Technology Based on Key Features

文章首先分析了关键特性的主要分类,包括产品、装配工序及制造工序关键特性,科学分析制造装配过程中误差累积情况,把关键特性分解传递至具体零部件与工艺过程;其次在数字化技术的协助下对各部段的关键特征进行容差分配处理,将处理所得信息整合至柔性装配数据集内,以为产品和工装生产制造、检测检验等提供可靠依据.加大零件与各个装配环节关键特性的检测与监管力度,能明显优化航空产品的装配质量,提升工作效率.

Firstly,the main classification of key features is analyzed,including the key features of products,assembly processes and manufacturing processes,the accumulation of errors in the manufacturing and assembly process is scientifically analyzed,and the key features are decomposed and transmitted to specific parts and processes.Secondly,with the assistance of digital technology,the key features of each section are subject to tolerance assignment and processing,and the processed information is integrated into the flexible assembly data set,so as to provide a reliable basis for products and tooling manufacturing,testing and inspection.Increasing the detection and supervision of key features of parts and each assembly link can significantly optimize the assembly quality of aviation products and improve work efficiency.
