龙门刨床电气控制系统设计茹亮摘要目前中国在世界上是机床消费的第一大国，并正在由制造大国向制造强国发展，数控机床是制造业的关键设备，数控维修和改造正在成为制造业的新兴产业，其产生和发展有着深刻的社会背景和经济背景。（1）我国现有数以万计的陈旧落后的机床，这些是机床大修和数控化改造业赖以生存的现实基础之一。（2）20世纪进口的大量二手数控设备已进入维修和改造的高峰期。（3）机床及数控设备造价高昂，显著的经济效益是数控改造行业发展的动力，一般改造的费用仅为购置新设备费用的30%左右。（4）通过数控改造可以进一步满足用户对设备的工艺要求以获取更大的效益。本文目的就是对龙门刨床进行PLC改造，提高其工作的效率。PLC作为一种新型的控制装置与传统的继电器控制系统相比具有时间响应快、可靠性好、控制程序可随工艺改变、易与计算机连接、维修方便、体积小、重量轻和功耗底等诸多高品质与功能。从而减少其维修时间，提高其工作效率。对于电气车间龙门刨床PLC的研究和实际应用都具有非常高的价值。关键词：龙门刨床,改造,数控化,PLCElectricalcontrolsystemdesignofPlanningmachineAbstractAtpresentChinaistheworld'slargestmachinetoolconsumerandismanufacturedbythemanufacturingpowertopowerthedevelopmentofCNCmachinetoolsisthekeytomanufacturingequipment,maintenanceandimprovementofnumericalcontrolmanufacturingisbecominganemergingindustry,itsemergenceanddevelopmentofThereisaprofoundsocialbackgroundandeconomicbackground.(1)tensofthousandsofChina'scurrentoutdatedandbackwardinmindthemachine,thesearemajorrepairsandCNCmachinetoolindustryinthetransformationoftherealityofsurvivaloneofthebases.(2)20thcentury,alargenumberofimportedsecond-handCNCequipmenthasenteredthemaintenanceandimprovementofthepeak.(3)AndCNCmachinetoolequipmentwillcostasignificanttransformationoftheeconomicbenefitsoftheNCdrivingforceforthedevelopmentoftheindustry,thegeneraltransformationofthecostoftheacquisitionofnewequipmentonlycostsabout30%.(4)ThroughtheNCcanbefurthermodifiedtomeetuserrequirementsforprocessequipmentinordertoobtaingreaterbenefits.Thepurposeofthispaperisthetransformationofdouble-housingplanertoPLCtoenhancetheefficiencyofitswork.PLCasanewtypeofcontroldevicewiththetraditionalrelaycontrolsystemswithfastresponsetime,reliability,andcontrolproceduresmaychangewithtechnology,easycomputerconnectivity,easymaintenance,smallsize,lightweightandpowerconsumptionattheendofandmanyotherhigh-qualityandfunction.Soastoreducetheirmaintenancetimeandimprovetheirworkefficiency.Workshopfortheelectricaldouble-housingplanerPLCresearchandpracticalapplicationshaveveryhighvalue.Keywords:Gantryplaner,alteration,NC,PLC目录1绪论..............................................................11.1龙门刨床简介..................................................11.1.1龙门刨床定义..............................................11.1.2龙门刨床的分类............................................11.1.3龙门刨床的工作情况........................................11.2PLC简介.......................................................21.2.1PLC简述...................................................21.2.2PLC定义...................................................21.2.3PLC的发展历程.............................................31.2.4PLC的构成.................................................31.2.5PLC的特点.................................................31.2.6PLC分类...................................................31.2.7PLC应用...................................................41.3设计的提出和主要工作..........................
