摘要
本文主要研究了CA6140經(jīng)濟(jì)型中檔精度數(shù)控車床的縱向進(jìn)給及導(dǎo)軌潤滑機(jī)構(gòu)的設(shè)計(jì)及其改造。本文對數(shù)控車床縱向進(jìn)給系統(tǒng)的設(shè)計(jì)與改造方案進(jìn)行了重點(diǎn)論述，對該機(jī)構(gòu)的主要組成部件:滾珠絲杠副、交流伺服電機(jī)、聯(lián)軸器等進(jìn)行了設(shè)計(jì)計(jì)算與選型。其中對滾珠絲杠副、交流伺服電機(jī)的設(shè)計(jì)計(jì)算及選型作了詳細(xì)論述。進(jìn)行這一設(shè)計(jì)主要是為了進(jìn)一步地提高數(shù)控車床縱向進(jìn)給機(jī)構(gòu)的定位精度，重復(fù)定位精度以及改造手動進(jìn)給裝置，以使其能夠可靠地運(yùn)行，且能滿足各項(xiàng)性能指標(biāo)的要求,達(dá)到預(yù)期的結(jié)果,即滿足設(shè)計(jì)任務(wù)書的要求。最后, 本文還對各個(gè)零部件進(jìn)行了設(shè)計(jì),并繪制了全部零件圖以及該數(shù)控車床縱向進(jìn)給機(jī)構(gòu)的裝配圖。此結(jié)構(gòu)簡單可靠,可應(yīng)用于相似的各類數(shù)控車床上。

Abstract
This article mainly told the research, the designing and transformation on the longitudinal motion system and track lubrication mechanism of CA6140 economic medium precision NC machine. The article made a brilliant exposition on the designing and transformation scheme of the longitudinal motion system and track lubrication mechanism of NC machine. The article also exposed brilliantly the mechanism’s mail parts: the ball-race bearing, the servo-electric machine, the coupling and so on. Doing the design is for the sake of improving the site precision, duplicate site precision and transformating the Longitudinal motion system .So it can work credibility, meet the request of every property norm, come to the expected consequence, and fulfill the require of design assignment list. Besides, the author has designed and drawed all of mechanism’ parts, and also drawed the assemble chart. This mechanism is simple and reliable, it can apply to every similar NC machine.
Key words: NC machine Longitudinal motion system Track lubrication mechanism
