毕业论文 飞轮壳体车削夹具设计 学 院 继续教育学院 专 业 机械08（本） 学生姓名 周 涵 指导教师 徐 长 顺 摘　 要 柴油机飞轮壳体是柴油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。 柴油机飞轮壳体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、类型和毛坯的制造形式。本设计通过对飞轮壳体结构的分析，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。并根据加工方案对飞轮壳体夹具进行设计。 ??? 柴油机飞轮壳体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。 ??? s 关键词：飞轮壳体,工艺方案?,夹具设计 Abstract Flywheel housing on the engine is a very typical parts,on the one hand, it anchored cylinder diesel engine after the end of flywheel energy storage for protective enclosures; the other hand, It is also the connecting support components of the housing of Diesel clutch. The external and internal quality of flywheel housing either impact on the overall diesel beautiful or affect the overall performance of diesel engines. The main structure of the flywheel housing of 110 diesel engine??is the complex shape, thin wall and uneven, processing site, difficult process, various surface processing and processing Kong have higher accuracy. In this paper,the development of routes were based on the characteristics of components of the analysis components. Secondly, the identification of the parts of the production program, the type and manufacturer of rough form. Based on the first chapter of the analysis of two routes, its comparative analysis, According to its comprehensive advantages and disadvantages of other first benchmark, the first after crude refined, after the first meeting of the main principles of the machining program, as well as procedures for the detailed design. The fixture parts of??the flywheel housing of 110 diesel engine according to of the design characteristics of the thin-walled parts is parts. Clamping in the process vulnerable to deformation, thus affecting the accu
