盐城工学院本科生毕业设计说明书 2008基于三维的柴油机气缸体三面钻削组合机床总体及夹具设计摘要：本课题来源：盐城市江淮动力集团的ZH1105W柴油机。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，需要设计一种组合机床来改善柴油机气缸体的加工情况。本课题设计的组合机床是针对ZH1105W柴油机气缸体钻左侧面（即水箱面）上11个孔，钻右侧面（即油底壳面）上21个孔，钻后盖板（缸尾）钻11个孔，共计43个孔同时加工。该设计的内容包括总体设计和夹具设计两个方面。总体设计中仔细分析了被加工零件的加工工艺性，选择了加工的定位基准及夹紧方案，合适的切削用量、刀具及机床的配置型式设计，合适的结构方案，完成“三图一卡”的绘制。在夹具设计时，采用了“三平面”定位的方案来消除工件的六个自由度，并有同时加工零件三个表面的可能，能够相对的集中工序，提高生产率。夹紧采用了液压夹紧装置，优点是夹紧力大,夹紧可靠。本次设计的组合机床结构简单，效率高，使用寿命长，可以满足设计要求。关键词：组合机床；夹具；柴油机气缸体；钻削The Overall and Fixture Design of Three Plane Drilling Combined Machine Based on 3D for Diesel Engine Cylinder BlockAbstract: The subject comes from Jiangdong Dynamic Group, Yancheng. The diesel engine cylinder block 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 diesel engine cylinder block. The combined machine is designed for drilling 11 holes on the left side of the ZH1105W diesel engine cylinder block , 21 holes on the right side and 11 holes on the back side. This means that processing a total of 43 holes at the same time. The design element includes overall design and fixture design. In fact, the design processing of the overall design is to analysis the manufacturing process of the processed part detailly ,to choose the positioning base,clamping programme,and appropriate cutting data the configuration type of machine, to design the structure of the matchine and drawn “three draft and one card”. During the fixture design, Three plane Dosition is used to eliminate the six-degree of freedom and it is possible to process three surface of the part at the same time so as to closer working step and increase productivity. Hydraulic clamping device whose advantage is the large clamping force and high reliabity. The design of combined machine has a simple structure, high efficiency and long service life ,Which can meets
