导辊除锈机床设计说明书.doc

I摘要随着机械工艺技术的不断创新,机械装备更是日新月异,各类运输机械和轧机上的滑动导轨装置逐渐被滚动导轨导辊所代替。导辊的工作条件十分恶劣,易受到输送物件的强冲击工作时与接触物件产生的摩擦磨损与疲劳磨损以及冷热刺激等,这些都会使导辊的表面发生锈蚀现象。长时间的锈蚀会影响导辊的表面强度,如不及时清理,会影响设备的正常工作。导辊除锈机可以对导辊表面的锈迹进行及时彻底的清理,从而保证输送机械工作的正常进行。除锈机的种类很多,其中使用范围最广的是抛丸机和酸洗机。前者机身大,结构复杂适用于大件型材。后者使用经济方便,但除锈剂为酸基物质,难以清除油脂和污垢,废液处理难,除锈效果差。本设计的主要内容是设计一台结构合理,功能完整且精度满足要求的导辊除锈机。该除锈机可以对不同长度和直径的导辊完成表面除锈。除锈机床主要部件如床身,主轴箱等参照外圆磨床,主要除锈原理是使用电机带动钢丝刷对导辊表面进行打磨,来去除松动或翘起的氧化皮、铁锈、焊渣等。关键词导辊除锈机床IIAbstractWiththemachineryandtechnologyinnovation,mechanicalequipmentischangerapidly,alltypesoftransportmachineryandmillonaslideraildevicehasbeenreplacedbytherollingguideGuideroller.Guiderollverypoorworkingconditions,subjecttothestrongimpactoftransportingobjectsobjectwhenworkingwithcontactfrictionandwearandfatiguewearhotandcoldstimulation.Willmaketherollersurfacerustingphenomenon.Longtimecorrosioncanaffecttheguiderollersurfacestrength,ifnotclearintime,willaffectthenormaloperationofequipment,derustingmachineguiderollerofrollersurfacerustaretimelyandthoroughcleaning,soastoensurethenormalworkingofconveyingmachinery.Rustcleaningmachineofmanykinds,themostwidelyusedistheshotblastingmachineandpicklingmachine.Thefuselage,complexstructuresuitableforlargesection.Thelatteruseseconomicconvenience,butrustremoverforacidbasematerial,itisdifficulttoremovegreaseanddirt,wastewatertreatment,cleaningeffectispoor.Themaincontentsofthisdesignistodesignareasonablestructure,completefunctionandaccuracycanmeettherequirementsoftheguiderollerdescalingmachine.Therustremovingmachinecanbeofdifferentlengthsanddiametersoftheguiderollersurfacederusting.Derustingmachinetoolsmaincomponentssuchasbed,spindleboxofhorizontallathemainreference,usingtoolssuchaswirebrushonthesurfaceoftheguiderollergrinding,canberemovedbylooseningortiltoftheoxidescale,rust,weldingslag.KeywordsGuiderollerderustingmachineIII目录摘要..........................................................................................................................IAbstract.....................................................................................................................II目录.......................................................................................................................IIICONTENTS..............................................................................................................V第1章绪论........................................................................................................11.1课题目的及意义.......................................................................................11.2国内外钢管除锈技术发展概况...............................................................21.2.1目前国内外除锈技术分析.............................................................21.2.2国内外现有的除锈设备................................................................61.2.3国外除锈设备的新发展.................................................................71.3本课题的任务及技术要求.....................................................................101.3.1课题任务......................................................................................101.3.2主要技术要求...........................................................................10第2章导辊除锈机床原理及方案设计.............................................................112.1导辊除锈机床的原理..............................................................................112.2导辊除锈机床的方案设计......................................................................112.2.1导辊除锈机床的结构设计方案...................................................122.2.2机床主要部件及其运动方式的选定...........................................122.3本章小结.................................................................................................14第3章结构设计................................................................................................153.1主轴箱结构设计.....................................................................................153.2刀架结构.................................................................................................173.3尾座结构设计.........................................................................................183.4溜板箱结构设计.....................................................................................183.5床身结构设计.........................................................................................193.6本章小结.................................................................................................20第4章设计校核................................................................................................214.1主轴V带设计........................................................................................214.2钢丝刷的计算.........................................................................................234.3蜗轮、蜗杆的设计.................................................................................25IV4.4主轴的设计与校核.................................................................................284.5轴承的设计计算.....................................................................................334.6滚珠丝杠副选择与校核.........................................................................344.6.1滚珠
