文档介绍：中文摘要
随着社会的不断发展,制造业的制造技术也在飞快的提高。我国在机械加工方面跟上了国外的发展,在普通的机床加工基础上,开始了用数控机床和加工中心进行加工。
对于大型结构的零件加工,需要设计一台专用机床进行加工。本文介绍了一台用于加工曲轴润滑油孔的专用钻床,该专机具有主轴调速范围大、行程长等特点,该机床适用于大型结构件深孔加工。使用结果表明,具有一定的实用性和应用价值。
设计的机床总体结构类似于一台三坐标摇臂钻床,能够在一次装夹中完成钻铰直油孔、切削多道工序。其大体工作原理如下:曲轴和夹具安装在固定不动的平台上,装有钻头的主轴箱随进给拖板实现钻削进给运动,工作位置的调整是通过大拖板横向运动、摇臂的上下运动、摇臂的转动来实现的。本机床原理正确,使用方便,加工效率高,精度有保证。使用本专用机床加工曲轴,大大缩短了加工时间和制造成本。

Abstract
By the continual development of society,making technology of manufacturing has improved processing of our country catch up with the development of the other countries in machining the basic mon machine tool’s machining,people begin to make with The Machining Center.
With the machining in accessory of good-sized structural,I need to design a special machine tool to machining. In this paper, a special machine tool for drilling lubricating hole and flange hole of crankshaft is introduced. The machine tool has some p rocessing characters, such as large range of speed governing for headshaft, long travel of feeding motion..The using result make know ,it has definite practicability and worthiness of adhibition.
The collectivity configuration of the machine tool is similarity as the radial dring and it has three can finish a lot of processes,for example drilling lubricating hole and so mainly working elements are: crankshaft and clamp are built on the imovable table-board. The headstock has aiguille and it follows dragging board e true the boring landscape orientation of dragging board, the up and down sport of shaking-arm and the running of dragging board turn up the modulating of working elements of machine tool is right and the use of it is efficiency of working is high and precision is to the special machine tool to process crankshaft than can shorten the time of processing and the making cost.
Key words: crankshaft; lubricating hole; radial dr
