东风D560国六后处理系统装配困难作业的分析与对策

The Analysis and Solution of the Difficult Operation of the Dongfeng D560 National Ⅵ Post-processing System

商用车汽车总装配过程,多多少少都会存在困难作业。减少或消除困难作业,是提升汽车总装配效率的有效途径之一。减少或消除困难作业的程度,体现一个工厂工艺水平的高低;同时消除困难作业可以降低工人劳动强度,提升质量水平。随着我国对环境保护要求力度进一步加大,国六排放标准已经成为强制要求。本文以东风D560国六后处理系统困难作业的分析与解决为例,详细论述了导致该问题的设计原因、部品质量控制原因,装配工艺方法原因等。并针对这些因素制定有效对策,实现困难作业的消除过程。

In the general assembly process of commercial vehicles,there are more or less difficult operations.Reducing or eliminating difficult operations is one of the effective ways to improve the overall assembly efficiency of automobiles.Reducing or eliminating the degree of difficult operations reflects the level of a factory’s technological level;at the same time,eliminating difficult operations can reduce labor intensity and improve quality.As our country’s requirements for environmental protection are further increased,the National Sixth Emission Standard has become a mandatory requirement.This paper takes the analysis and solution of the difficult operation of the Dongfeng D560 National Ⅵ post-processing system as an example,and discusses in detail the reasons for the design,quality control,and assembly process methods that led to the problem.And to formulate effective countermeasures against these factors to achieve the elimination of difficult operations.
