内容简介：

盐城工学院本科生毕业设计说明书 2009柴油机气缸体三面钻削组合机床总体及左主轴箱设计摘 要：柴油机气缸体是需要大量生产的零件。为了提高加工精度和生产效率，需要设计一台组合机床来改善柴油机气缸体的加工情况。本课题设计的是ZH1105柴油机气缸体三面钻孔组合机床。用于加工被加工零件左、右、后三个面上的共31个大小不等的底孔。根据被加工工件的特点以及加工工艺的要求，进行了总体设计。选定了定位基准，确定了机床的配置形式以及工件的定位夹紧方案，选择了合适的切削用量、刀具及动力部件。总体设计主要是绘制被加工零件工序图、加工示意图、机床联系尺寸总图和编制生产率计算卡。在完成总体设计的基础上，绘制了左主轴箱设计的原始依据图，拟订了传动系统，确定了传动参数，设计了轴的结构，进行了齿轮、轴等相关零件的强度校核计算。该设计布局合理，为使组合机床能尽快投入生产应用，配置结构中充分选用了标准件及通用部件。该机床工艺性良好、方案可行、有实际使用价值。关键词：钻孔；组合机床；主轴箱Design of General and Left Headstock of Modular Machine Tool for Drilling Holes on Three-Side of engine cylinder bodyAbstract: The engine cylinder body is a product which needs mass production. In order to prove the disposition and the production efficiency, need to design a high effective modular machine tool to improve the production of the truck gear box. The subject is to design a three-side modular machine tool for drilling 31 different holes on ZH1105 engine cylinder bodys left,right ,and behind. Based on the character and the process analysis of the work-piece, the designing system was made. After the location datum were designed, the disposition of machine and the mechanism clamping system being determined, the reasonable cutting data, the cutter and the power part were chosen. Overall to it is process into part process picture, process sketch map , lathe contact size general drawing and work out productivity calculate the card to draw mainly to design. The primitive basis charts of the left-side spindle box were drawn, the transmission system and the parameter were drafted. Then the structure of the axis was designed and the intensity checks of the components of the gear ,axis and so on were carried on .This design layout is reasonable, to make the combination machine tools can be used as soon as possible into production, structure and fully chose standard components. This machine is
