摘要随着当今工业设备对精密程度的要求越来越高，加工设备的机械加工设备的加工的精密程度也要求越来越高。而在中国的机械加工设备的车床中普通车床占了很大比例。这已经越来越制约着当今工业的发展。而数控机床由于价格昂贵，且需要较高技术的加工工人。所以对机床进行自动化改造很是必要。本篇论文是在对普通卧式车床C6150的基础上对其进行自动化改造。作者在搜索、查阅研究大量有关资料的基础上，对机床自动化改造技术进行了深入的研究和分析，并描述了机床控制系统的设计。整个改造过程主要对车床纵、横向进给系统进行改造，选用自动转位刀架，由脉冲发生器来加工所需要的螺纹。整个控制系统以8031型号的单片机为中心，通过编程对机床的驱动设备进行控制以达到所需要的加工程度。关键词：机床改造；自动化机床；控制系统ABSTRACTWiththedevelopmentofindustryequipment,theprecisionrequiredofindustryequipmentismoreandmorehigh.Themoreandmoreprecisionofequipmentwhichmachinedtheindustryequipmentisrequired.ButinChinathecommonlathehaveaverygreatcomparisoninthemachinedequipment,thisalreadyrestrictthedevelopmentofindustrialnowadays.ButtheCNlatheismoreexpensive,andneededworkerswithhighertechnically.Soitisanecessityverymuchtomodifythecommonlathetolathesautomatic.ThispaperisinthefoundationofthecommonnesshorizontallatherC6150andmodifiedittoLathesautomatic.Theauthorhasperformedthefurtherresearchandforthelathesautomaticmodificationonthebasisoftheconstantconsultationofabundantrelativedocuments,whichfocusesondescribingthedesignofcontrolofthemachine.Themaintomodifythelatheistomodifytheportrait,horizontalentertothesystemintheWholemodificationprocessandchoosetheautomatickniferestandbeprocessedthethreadneedbypulser.ThewholecontrolsystemwiththeCPUof8031istocontrolthemachineforcenter,throughaplaitdistancedrivetoolmachineanequipmentstocarryoncontroltoattainneedofprocessdegree.Keywords:MachineryToolReform；Lathesautomatic；Servosystem目录第1章绪论..................................................11.1数控机床与数控技术.......................................11.1.1数控机床与发展趋势.................................11.1.2数控技术...........................................21.1.3数控技术发展趋势...................................41.1.4数控机床目前在工业中的地位.........................61.2数控改造的必要性.........................................61.2.1机床与生产线数控化改造的市场.......................71.2.2机床数控化改造的必要性.............................71.3数控化改造的内容及优缺...................................81.4对我国数控技术和产业化发展的战略见解....................101.4.1形势考虑..........................................101.4.2发展策略..........................................101.5本文的选题及主要研究内容................................111.5.1本文的选题........................................111.5.2主要研究内容......................................11第2章数控车床总体改造方案及机械部分设计...............132.1设计要求................................................132.1.1设计基本思路......................................132.1.2改造方案的确定....................................132.1.3设计目的..........................................132.1.4总体方案设计......................................152.2滚珠丝杠的设计计算与选用................................152.2.1滚珠丝杠..........................................152.2.2纵向滚珠丝杠的设计与计算..........................162.2.3横向滚珠丝杠的设计与计算..........................242.2.4滚珠丝杠的安装与使用...........
