C6150普通机床的自动化改造毕业论文.doc

普通车床的自动化改造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普通车床的自动化改造ABSTRACTWiththedevelopmentofindustryequipment,theprecisionrequiredofindustryequipmentismoreandmorehigh.Themoreandmoreprecisionofequipmentwhichmachinedtheindustryequipmentisrequired.ButinChinathecommonlathehaveaverygreatcomparisoninthemachinedequipment,thisalreadyrestrictthedevelopmentofindustrialnowadays.ButtheCNlatheismoreexpensive,andneededworkerswithhighertechnically.Soitisanecessityverymuchtomodifythecommonlathetolathesautomatic.ThispaperisinthefoundationofthecommonnesshorizontallatherC6150andmodifiedittoLathesautomatic.Theauthorhasperformedthefurtherresearchandforthelathesautomaticmodificationonthebasisoftheconstantconsultationofabundantrelativedocuments,whichfocusesondescribingthedesignofcontrolofthemachine.Themaintomodifythelatheistomodifytheportrait,horizontalentertothesystemintheWholemodificationprocessandchoosetheautomatickniferestandbeprocessedthethreadneedbypulser.ThewholecontrolsystemwiththeCPUof8031istocontrolthemachineforcenter,throughaplaitdistancedrivetoolmachineanequipmentstocarryoncontroltoattainneedofprocessdegree.KeywordsMachineryToolReformLathesautomaticServosystem普通车床的自动化改造1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.............................322.3电机与滚珠丝杠连接用一级减速齿轮的设计与校核...........342.3.1齿轮传动.........................................342.3.2纵向减速齿轮的设计与校核.........................352.3.3横向减速齿轮的设计与校核.........................392.4进给系统的步进电动机的计算与选择.......................422.4.1步进电动机.......................................422.4.2纵向电机的计算与选择.............................44普通车床的自动化改造22.4.3横向电机的计算与选择.............................472.5电动刀架选择与介绍.....................................50第3章主轴脉冲发生器介绍与选型...........................523.1光电编码器原理.........................................523.2主轴脉冲发生器的安装...................................533.3主轴脉冲发生器的选择...................................54第4章普通车床自动化改造的单片机控制...................564.1系统设计...............................................564.2用单片机控制系统电路...................................584.2.1存储器扩张电路...................................584.2.2面板操作键和功能选择开关.........................614.2.3功能选择开关.....................................624.2.4键盘、显示器接口电路.............................634.2.5步进电动机驱动电路设计...........................644.2.6M.S.T接口.......................................674.2.7辅助电路设计.....................................68第5章小结........................................69参考文献...........................................70英文原文...........................................71中文译文..............................错误未定义书签。致谢............................................71
