摘 要
车床是主要用车刀对旋转的工件进行车削加工的机床,而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。
本设计是把6136普通车床改造成全自动液压专用机床，对车床结构作了设计，在设计过程中考虑到车床的形

成工艺，床身的受力分析和床身的热态分析。该设计满足了全自动液压专用机床的加工精度要求，整体性能

稳定。

Abstract
Lathe is mainly used tool for rotating workpiece turning processing machine tools, and special

machine tools commonly used multi-spindle, multi-tool, process, surface or transfer process at

the same time, the production efficiency is higher than general machine tools several times or

more. Due to gm parts have standardization and seriation, can be flexibly configured according

to need, to shorten design and manufacturing cycle. So dedicated machine tool has both the

advantages of low cost and high efficiency, is widely used in large, mass production, and can

be used to form automatic production line.
Dedicated box is generally used in the machine or special shaped parts. When the workpieces are

generally not rotate, the by the rotation of the tool movement and relative feed movement of

cutting tool and workpiece, to implement a drilling, reaming, counter boring, reaming, boring,

milling plane, cylindrical internal and external screw thread and cutting processing and face,

etc. Some combination machine tools using turning head clamping workpiece to rotate, the tool

feed movement, also can achieve some of the revolving body parts, such as flywheel, vehicle

driving axle half shaft, etc.) of the cylindrical and face processing.
This design is put 6136 ordinary lathe to transform into a special machine, automatic hydraulic

structure design of the lathe, in the design process of forming process considering lathe bed,

bed of the thermal stress analysis and modal analysis. The design of automatic hydraulic meet

the special machine machining accuracy requirement, and overall stability.
