左驱动轴壳右端面孔系加工专用机床设计 摘 要 随着自动化生产能力的提高，现代工厂中出现需要组合机床的场合越来越多，组合机床是以通用部件为基础，配以工件特定外形和加工工艺设计的专用部件和夹具，组成的半自动或自动专用机床。它一般采用多轴，多刀，多工序，多面或多工位同时加工的方式，生产效率比通用机床高几倍至几十倍。由于通用部件已经标准化合系列化，可根据需要灵活配置，能缩短设计和制造周期。因此，组合机床兼有低成本和高效率的优点，在大批量生产中得到广泛应用，并可用以组成自动生产线。 本次毕业设计的题目是“左驱动轴壳右端面孔系加工专用机床设计”。本人的设计的主要内容是：分析左驱动轴壳零件的加工工艺；绘制工序图；根据本工序工艺内容需要进行机床总体设计；完成夹具、主轴箱设计；通过此设计，本机床完全能满足设计要求，与传统的机床相比，本机床具有自动化程度高，生产率高，精度高等优点。 关 键 词：组合机床，工艺，夹具，主轴箱  MACHINE DESIGN OF THE RIGHT SIDE OF THE LEFT DRIVE SHAFT SHELL DRILLING ABSTRACT With automatic production capability is improved, the modern factories in need of modular machine tool, the combination of more occasions based on general parts, match with work-piece specific shape and process design of special components and fixtures, composed of semi-automatic or automatic special machine. It usually adopts the multi-axial, knife, processes, and multi-faceted or multistage and processing, production efficiency than general machine high several times or more. Due to the common parts have standard series, can according to the combined flexible configuration, can shorten the cycle of design and manufacture. Therefore, the combination machine has the advantages of low cost and high efficiency, in large, mass production is widely used, and the automatic production line can be used to composition. This?graduation?projects?topic?is “machine design of the right side of the left drive shaft shell drilling ”.my job is analying the crafts of the drive shaft ;painting process chart ;designing the machine ,fixture ,spindle box. With this design, this machine can meet the design requirements, and the traditional compared to the machine, this machine has high automation, high productivity and high precision.
