摘要
此设计是经济型中档精度数控车床横向进给系统。面对我国目
前机床数量少、工业生产规模小的特点,突出的任务是用较少的资金
迅速改变机械工业落后的面貌。而数控车床(及其系统)已经成为现
代机器制造业中不可缺少的组成部分。所以,实现这一任务的有效的、
基本的途径就是普及应用经济型数控机床。
进给系统是由伺服电机经滚珠丝杠拖动工作台来完成的所以设
计涉及伺服电机的选择,滚珠丝杠设计等。目前绝大部分的机床的横
向进给均是采用滚珠丝杠来传递运动的,传动的精确性主要取决于丝
杠支承形式,丝杠与伺服电机的联接方式。在设计中充分考虑到这两
个问题,并且,设计精度须达原始数据。

数控机床横向进给设计.
This design is the feeding operation of numerical control lathe with
economic type of intermediate precision
In view to the quantity of machine tools in our country is not enough and
the scale of industrial production is little at present, the outstanding
task is to change our mechanical industrial appearance with less fund in
short order.
And the numerical control lathe and its system have e an
important part in modern manufacturing industry.
So, to realize this task, the effective and the basic channel is to use
this economic type of numerical control lathe widely.
Feeding system goes normally with the ball screw which is droved by
servo-motor dragging the workbench up and down.
So, this design includes the option of servo motor, the design of ball
screw and so , the landscape orientation feeding of most machine
tools is offered by ball screw. The accuracy of the transmission depends
on mainly the form of the screw supports and the way of how screw and
servo-motor to be joined. Besides the precision of the design needs Bases
the primal data.
Consider these two questions in the design sufficient.
