文档介绍：中文摘要
我们本次毕业设计的题目是CA6140床头箱体工艺以及装备的设计,工艺是一门很大的课程。零件的机械加工、热处理、表面处理,部件和产品的装配等是直接改变毛坯的形状、尺寸、相对位置和性能的过程,称为机械制造工艺过程,简称工艺过程。工艺过程是生产过程的主要组成部分,其中零件的机械加工是采用合理有序安排的各种加工方法逐步地改变毛坯的形状、尺寸和表面质量使其成为合格零件的过程。
组合机床是以通用部件为基础,配以按工件特定形状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。  组合机床一般采用多轴、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和系列化,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、大量生产中得到广泛应用,并可用以组成自动生产线。
通过对变速箱体零件图的分析,制定其工艺过程,确定组合机床形式,绘制三图一卡;以及对专用部件多轴箱的设计。
组合机床的数量和品种正在日益增长,它们已在我国机械制造工业上得到广泛应用。

Abstract
The machine of spare parts process, hot processing, surface processing, assemble etc. of parts and product is direct to change the shape, size, opposite position of the semi-finished product and the process of the function, be called the craft process of the machine manufacturing and call craft craft process is mainly a production line to constitute part, among them, the machine of spare parts process is adoption reasonable have a preface arrangement of various process a square the hair gradually changes semi-finished product of shape, size and surface quality make it e the process of qualified spare parts.
The aggregate machine-tool is take the general part as a foundation, matches by presses the work piece specific shape and the processing technological design special-purpose part and the jig, position semiautomatic or the automatic special purpose machine □aggregate machine-tool generally selects the method which multiple spindle, the multi- knives, the multi- working procedures, the multi- surface or the multi- locations simultaneously processes, production efficiency ratio general engine bed high several times to several dozens times. Because the general part already the standardization and the seriation, might according to need nimbly to dispose, could reduce the design and the manufacture cycle. Therefore, the aggregate machine-tool concurrently has the low cost and the high efficiency merit, in large quantities of, the mass productions obt
