四缸曲轴钻扩大头孔专用机床设计+CAD图纸
诚然，这次我的毕业设计课题为四缸曲轴钻扩大孔专用机床设计，四缸曲轴作为汽车业最为普遍的零部件，起产量是非常大的，并且四缸曲轴有可以成为汽车发动机的一条核心桥梁，它的质量要求直接影响着一台发动机，甚至是一辆车的优劣。虽然我课题的这个步骤是整个汽车生产的极小一环，但若是我能设计出一个高效的设备，仍然是具有价值和意义的。
在接下来的说明阐述中，我便将介绍我的四缸曲轴钻扩大孔专用机床设计，为了呈现出我设计的重点——多轴高效钻床，我会详细说明我的组合机床多轴箱设计，并列写出具体的参数计算过程以及关键的齿轮传动系统图，最后是专用夹具的设计过程。

Abstract The development of industrial manufacturing is a benchmark for the progress of the country, and how to reflect the strong industry manufacturing industry, it is from the product quality, production efficiency and so on.. Is not difficult for us to from an industrial powerhouse Germany seen their pipeline is banned industrial robots, a station can be processed in many kinds of, which is the production efficiency is famous in the world.
Indeed, the graduation design topic for four cylinder crankshaft drill expanding hole special machine tool design, four cylinders crankshaft automobile industry, as the most common parts, yield is very large, and four cylinder crankshaft can become a central bridge of automobile engine, its quality to seek to directly affect the engine, even the pros and cons of a car. Although this step of my subject is a minimal ring of the entire car production, but if I can design a highly efficient equipment, is still valuable and meaningful.
In the next explain in, I will introduce my four cylinders crankshaft drill to extend special drilling machine design, in order to show I design the focus of multiple axes, drilling machine, I will my multiple spindle box of modular machine tool design are described in detail, tied to write specific parameters of the calculation process and the key of the gear transmission system graph, and finally the special fixture design process.
Keywords：High efficiency；Multiple axis drilling； Gear axle ；Special fixture
