数控车床横向进给机构的设计(含CAD零件图总图)(任务书,论文说明书10000字,CAD图纸26张)
摘要
本文作者主要研究了φ400mm经济型中档精度数控车床的横向进给机构的设计及其改造。其中,主要论述了两种不同的横向手动进给装置,亦即两种不同的设计方案。通过对两种不同设计方案的优缺点比较,根据提高定位精度、重复定位精度等因素,最终确定设计方案二为本次设计的设计方案。在设计计算中, 本文作者主要对数控车床横向进给机构的主要组成部件:滚珠丝杠副、同步带、同步带轮、交流伺服电机、导轨副及其自动转位刀架等进行了设计计算或选型。其中对滚珠丝杠副、同步带、交流伺服电机以及自动转位刀架的设计计算及选型作了重点论述。此外, 本文作者还对各个零部件进行了设计,并绘制了全部零件图以及该数控车床横向进给机构的装配图。此结构简单可靠,可应用于相似的各类数控车床上。

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 .
