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。本课题针对气缸体顶面上 6xM8 孔钻削这一特定工序而设计的一台专用立式组合机床。本设计中,在充分数据计算的基础上对标准通用零件做了仔细选择,并依据被加工零件的结构特点,加工部位的尺寸精度,表面粗糙度要求,以及定位夹紧方式,工艺方法和加工过程中所采用的刀具,生产率,切削用量情况等设计了结构合理的多轴箱。

Abstract
With the automated production capabilities, modern factories, more and more occasions that require machine tool, machine tool is based ponents, together with the particular work piece shape and processing technology specifically ponents and fixtures, consisting of semi-automatic or automatic machine tools. It monly used multi-axis, multi-tool, multi-process, multi-faceted or multi-station at the same time processing, production efficiency several times or more high than the general-purpose machine tools. ponents have been standardized together the series can be flexibly configured; can shorten the design and manufacturing cycle. Therefore, bination of machine both the advantages of low cost and high efficiency, have been widely used in mass production, and can be used to form an automatic production line. This topic for the top surface of the cylinder block 6xM8 hole drilling this particular process, a dedicated bination of machine tools, in this design, on the basis of sufficient data to calculate the standard generic parts carefully selected based on the structural characteristics of the parts to be processed, the processing parts of the dimensional accuracy, surface roughness, as well as a way of locating and clamping process and processing the tool used in the process, productivity, cutting usage was designed rational structure of the multi-axle box.
