水射流切割机机械结构设计

水射流切割机机械结构设计摘要水射流切割技术是近几十年来新兴的一种环保高效的冷加工技术。与目前的加工制造技术相比它所具有众多优点，如切割方向无限制、材料几乎没有热变形物化属性影响极小、切割精度高速度快并且成本低等优点。特别是在工业切割和清洗领域水射流切割技术应用广泛。本设计将水射流切割技术应用于切割岩芯实验材料，解决目前岩芯切割试验材料形状不符问题。针对目前岩芯属性测量试验中物料的形状、力学性能难以满足实验要求的问题，设计一种基于水射流切割技术的岩芯制备机。使用水切割的方法，对岩芯进行切割。和传统的切割方法相比，采用这种加工方法可极大的减少材料的热变形提高了加工精度，同时噪音相对较小，工人的工作环境得到改善。采用XYZ悬臂滑轨结构、机电一体化与超高压系统技术联合使用，实现对水射流切割岩芯制备机设计。与目前的岩芯制备技术相比，满足了岩芯属性测量试验对物料的要求。水射流切割技术必将是一个发展趋势。本文对水射流切割岩心制备机机械结构设计以及高压零部件的选型做了详细地说明。关键字：水射流切割；岩芯切割；结构设计WaterjetcuttingrockmechanicaldesignofpreparationmachineABSTRACTWaterjetcuttingtechnologyisemerginginrecentdecadesanenvironmentallyfriendlyandefficientcoldtechnology.Comparedwithcurrentmanufacturingtechniquesithasmanyadvantages,suchascuttingdirectionunrestricted,materialpropertiesalmostnoheatdistortionmaterializedminimalimpact,cutprecisionhigh-speedfastandlowcost.Inthefieldofindustrialcuttingandcleaningapplicationsarerelativelyextensive.Thedesignofwaterjetcuttingtechnologytocutcoreexperimentalmaterials,solvethecoreproblemdoesnotmatchtheshapeofthecuttingtestmaterial.Fortheshapeofthecorematerialpropertymeasurementtestspresent,themechanicalpropertiesoftheproblemaredifficulttomeetthetestrequirements,thedesignofawater-jetcuttingcorepreparationmachine.Usewatercuttingmethod,thecorecutting.Comparedwithtraditionalcuttingmethods,usingthisprocessingmethodcangreatlyreducethethermaldeformationofthematerialtoimprovethemachiningprecision;whilethenoiseisrelativelysmall,theworkers'workingenvironmenthasbeenimproved.XYZcantileverstructureusingrail,mechatronicsystemsandultra-highpressuretechnologyincombination,toachievethewaterjetcuttingcorepreparationmachinedesign.Comparingwiththecurrentcorepreparationtechnology,theresultcanmeetthepropertymeasurementtestrequirements.Waterjetcuttingtechnologywillbeatrend.Thispaperispreparedforwaterjetcuttingmachinemechanicaldesignandselectionofhigh-pressurecorecomponentsmadedescribedindetail.Keyword:Water-jetCutting；Cuttingcore；StructureDesign目录第一章绪论....................................................................................................................11.1水射流技术的发展历史及应用............................................................................................11.2水射流切割的特点................................................................................................................11.3水射流切割技术的应用........................................................................................................21.4水射流切割岩芯制备机机械结构设计背景........................................................................2第二章水射流切割机的结构设计................................................................................32.1水射流切割的基本原理........................................................................................................32.2水射流切割岩芯制备机机机械结构方案.............................................错误!未定义书签。2.2.1水射流切割岩芯制备机机械结构设计要求..............................错误!未定义书签。2.2.2方案选择......................................................................................错误!未定义书签。2.3水射流切割岩心制备机机械结构设计计算.........................................错误!未定义书签。2.3.1增压器的设计与计算..................................................................错误!未定义书签。2.3.2油泵及油泵电机的确定..............................................................错误!未定义书签。2.3.3水泵以及水泵电机的确定选择..................................................错误!未定义书签。2.3.4蓄能器的型号选型......................................................................错误!未定义书签。2.3.5液压缸的设计..............................................................................错误!未定义书签。2.3.6悬臂滑轨的选择..........................................................................错误!未定义书签。2.3.7喷嘴结构的设计..........................................................................错误!未定义书签。第三章机床的误差来源与分析.....................................................错误!未定义书签。3.1误差和误差来源.....................................................................................错误!未定义书签。3.1.1研究误差的意义..........................................................................错误!未定义书签。3.1.2误差的来源..................................................................................错误!未定义书签。3.2误差传递的规律.....................................................................................错误!未定义书签。3.3水射流切割岩芯制备机的误差以及较小误差的措施.........................错误!未定义书签。3.3.1自身误差和安装误差..................................................................错误!未定义书签。3.3.2减小误差采取的措施..................................................................错误!未定义书签。第四章水射流切割机的维护和润滑.............................................错误!未定义书签。4.1液压元件的维护与安装.........................................................................错误!未定义书签。4.2XYZ滑轨光杆轨道、丝杠螺母副以及轴承的维护与润滑..................错误!未定义书签。第五章结论.....................................................................................错误!未定义书签。参考文献.............................................................................................错误!未定义书签。附录.....................................................................................................错误!未定义书签。英文原文..................................................................................
