1、中北大学分校 2007 届本科毕业设计说明书第 1 页 共 2 页110110 柴油机飞轮壳机械加工工艺规程及工艺装备设计柴油机飞轮壳机械加工工艺规程及工艺装备设计摘要摘要飞轮壳式发动机上一个非常典型的零件，它一方面挂靠在柴油机缸体的后端面用于储能飞轮的防护罩；另一方面，它也是柴油机离合器壳的连接支撑部件。其外观和内在质量及影响着柴油的整体的美观程度，也影响着柴油机的整体性能。110 柴油机飞轮壳的主要结构特点是形状复杂，壁薄且不均匀，加工的部位多，加工难度大，各个加工面和加工孔均要求较高的精度。本文首先根据零件的特点对零件进行了分析，为制定工艺路线作了基础。其次，确定了零件的生产纲领、类型和
2、毛坯的制造形式。依据第一章的分析拟定了两条工艺路线，对其进行了比较分析，综合其优缺点按照先基准后其它，先粗后精，先主后次的原则确定了加工方案，并对工序进行了详细设计。110 柴油机飞轮壳的夹具根据该零件的特点设计，该零件属于薄壁类零件，在裝夹过程中极易变形，因而影响精度甚至破坏零件。两套工装采用了恰当的定位和夹紧，既保证了零件的精度又确保了零件的完好加工，同时减少辅助工时，提高了劳动生产率。本文对飞轮壳进行了详细的工艺分析及研究，对本产品的工艺及其工装的设计探索出了一条切实可行的新路。关键词 飞轮壳 工艺方案 夹具设计Abstract Flywheel housing on the engin
