1、 1 摘 要 随着当今工业设备对精密程度的要求越来越高，加工设备的机械加工设 备的加工的精密程度也要求越来越高。而在中国的机械加工设备的车床中普 通车床占了很大比例。这已经越来越制约着当今工业的发展。而数控机床由 于价格昂贵，且需要较高技术的加工工人。所以对机床进行自动化改造很是 必要。本篇论文是在对普通卧式车床 CA6140 的基础上对其进行机电一体化 改造。 作者在搜索、查阅研究大量有关资料的基础上，对机床自动化改造技术 进行了深入的研究和分析，并描述了机床控制系统的设计。整个改造过程主 要对车床纵、横向进给系统进行改造，丝杠选用摩擦损失小，效率高，精度 高，寿命长的滚珠丝杠,电机选用步进

2、电机,电动机与滚珠丝杠用齿轮减速； 刀架改造成能自动换刀的回转刀架，由脉冲发生器来加工所需要的螺纹；整 个控制系统以 JKW-15T 型号的单片机为中心，通过编程对机床的驱动设备 进行控制以达到所需要的加工程度。 关键词关键词：机床改造； 自动化机床； 控制系统 2 ABSTRACT With the development of industry equipment, the precision required of industry equipment is more and more high. The more and more precision of equipment whic

3、h machined the industry equipment is required. But in China the common lathe have a very great comparison in the machined equipment, this already restrict the development of industrial nowadays. But the CN lathe is more expensive, and needed workers with higher technically. So it is a necessity very

4、 much to modify the common lathe to lathes automatic. This paper is in the foundation of the commonness horizontal lather CA6140 and modified it to Lathes automatic. The author has performed the further research and for the lathes automatic modification on the basis of the constant consultation of a

5、bundant relative documents, which focuses on describing the design of control of the machine. Screw on the choice of friction loss, high efficiency, high precision, long life of the ball screw, the electrical selected stepper motor, motor and the ball screw with gear deceleration.The main to modify

6、the lathe is to modify the portrait, horizontal enter to the system in the Whole modification process and choose the automatic knife rest and be processed the thread need by pulser. The whole control system with the CPU of JKW-15T is to control the machine for center, through a plait distance drive tool machine an equipments to carry on control to attain need of process degree.
