- 17D4变速箱壳体加工工艺制订与取力窗口面螺纹底孔专用钻床设计摘 要
17D4－00030－B变速箱是东风系列EQ6100汽车的基础零件之一。它把变速箱中的轴和齿轮等有关零件和机构联结为一个整体，使这些零件和机构保持正确的相对位置，以便其上各个机构和零件能正确、协调一致地工作。变速箱的加工质量直接影响变速箱的装配质量，进而影响汽车的使用性能和寿命。
专用机床一般采用多轴、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。因此专用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。专用机床一般用于加工箱体类或特殊形状的零件。加工时,工件一般不旋转,由刀具的旋转运动和刀具与工件的相对进给运动,来实现钻孔、扩孔、锪孔、铰孔、镗孔、铣削平面、切削内外螺纹以及加工外圆和端面等。有的组合机床采用车削头夹持工件使之旋转,由刀具作进给运动,也可实现某些回转体类零件(如飞轮、汽车后桥半轴等)的外圆和端面加工。

Abstract
17D400030B gearbox is one of the basic parts of Dongfeng series EQ6100 car. The relevant parts and mechanism in transmission shaft and gear connected as a whole, make these parts and institutions to maintain the relative position of the right, so that it can correct all agencies and parts, working in harmony. The processing quality of the gearbox directly affects the assembly quality of the gearbox, and then affects the service performance and the service life of the automobile.
Special machine tools are generally multi axis, multi knife, multi process, multi - or multi station processing at the same time, the production efficiency is higher than the general machine several times to several times. Due to the standardization and serialization of the general components, it can be configured flexibly according to the requirements. Therefore, the special machine tool has the advantages of low cost and high efficiency, and is widely used in a large number of mass production, and can be used to form an automatic production line. Special machine tools are generally used for machining box or special shape parts. When machining the workpiece is generally not rotated by the relative feed motion of the tool rotation and tool and workpiece, to achieve the drilling, reaming, boring, reaming, boring, cutting and milling, and the processing thread and the circle and etc.. There is a combination of rotating tool with clamping workpiece machining head to, by the tool feed motion, also can achieve some of the rotating parts (such as flywheel, car rear axle etc.) of the circle and the process.
Key words:The processing technology to make Aggregate machine-tool headstock drilling.
