摘要
此設(shè)計是經(jīng)濟型中檔精度數(shù)控車床橫向進給系統(tǒng) 。面對我國目前機床數(shù)量少、工業(yè)生產(chǎn)規(guī)模小的特點,突出的任務(wù)是用較少的資金迅速改變機械工業(yè)落后的面貌。而數(shù)控車床(及其系統(tǒng))已經(jīng)成為現(xiàn)代機器制造業(yè)中不可缺少的組成部分。所以,實現(xiàn)這一任務(wù)的有效的、基本的途徑就是普及應(yīng)用經(jīng)濟型數(shù)控機床。
進給系統(tǒng)是由伺服電機經(jīng)滾珠絲杠拖動工作臺來完成的所以設(shè)計涉及伺服電機的選擇,滾珠絲杠設(shè)計等。目前絕大部分的機床的橫向進給均是采用滾珠絲杠來傳遞運動的,傳動的精確性主要取決于絲杠支承形式,絲杠與伺服電機的聯(lián)接方式。在設(shè)計中充分考慮到這兩個問題,并且,設(shè)計精度須達原始數(shù)據(jù)。

Abstract
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 become 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 on.Now, 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.
