摘要
本文作者主要研究了φ400mm經(jīng)濟(jì)型中檔精度數(shù)控車床的橫向進(jìn)給機(jī)構(gòu)的設(shè)計及其改造。其中,主要論述了兩種不同的橫向手動進(jìn)給裝置,亦即兩種不同的設(shè)計方案。通過對兩種不同設(shè)計方案的優(yōu)缺點(diǎn)比較,根據(jù)提高定位精度、重復(fù)定位精度等因素,最終確定設(shè)計方案二為本次設(shè)計的設(shè)計方案。在設(shè)計計算中, 本文作者主要對數(shù)控車床橫向進(jìn)給機(jī)構(gòu)的主要組成部件:滾珠絲杠副、同步帶、同步帶輪、交流伺服電機(jī)、導(dǎo)軌副及其自動轉(zhuǎn)位刀架等進(jìn)行了設(shè)計計算或選型。其中對滾珠絲杠副、同步帶、交流伺服電機(jī)以及自動轉(zhuǎn)位刀架的設(shè)計計算及選型作了重點(diǎn)論述。此外, 本文作者還對各個零部件進(jìn)行了設(shè)計,并繪制了全部零件圖以及該數(shù)控車床橫向進(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
Main research φ 400 mm economical middle-grade precision numerical control crosswise of lathe, author of this text of summary, enter give design of organization and transform. Among them, have described two kinds of different entering horizontal and manually to the device, namely two kinds of different plans of design mainly. Compare through the pluses and minuses to two kinds of different plans of design , according to raising and orientate the precision , orient the factors, such as precision,etc. repeatedly, confirm plan of design two as the plan of design designed this time finally. In design in calculating, have lathe horizontal to enter give main composition part of organization to numerical more control authors of this text mainly: Ball guide screw vice, bring, bring wheel, exchange servo electrical machinery, vice guide and transfer to location knife rest, etc. design calculating or selecting type automatically in step in step. Among them guide screw vice to ball taking, exchange servo electrical machinery and transfer to location design of knife rest calculate and selecting type act as and expound the fact especially automatically in step. In addition author of this text go on and design to each spare part also, draw all part picture and lathe horizontal to enter give installation diagram of organization numerical control this. It is reliable that this is of simple structure, can apply to similar all kinds of numerical control lathes .
