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,alltypesoftransportmachineryandmillonaslideraildevicehasbeenreplacedbytherollingguide-Guideroller.Guiderollverypoorworkingconditions,subjecttothestrongimpactoftransportingobjects；objectwhenworkingwithcontactfrictionandwearandfatiguewear；hotandcoldstimulation.Willmaketherollersurfacerustingphenomenon.Longtimecorrosioncanaffecttheguiderollersurfacestrength,ifnotclearintime,willaffectthenormaloperationofequipment,derustingmachineguiderollerofrollersurfacerustaretimelyandthoroughcleaning,soastoensurethenormalworkingofconveyingmachinery.Rustcleaningmachineofmanykinds,themostwidelyusedistheshotblastingmachineandpicklingmachine.Thefuselage,complexstructuresuitableforlargesection.Thelatteruseseconomicconvenience,butrustremoverforacid-basematerial,itisdifficulttoremovegreaseanddirt,wastewatertreatment,cleaningeffectispoor.Themaincontentsofthisdesignistodesignareasonablestructure,completefunctionandaccuracycanmeettherequirementsoftheguiderollerdescalingmachine.Therustremovingmachinecanbeofdifferentlengthsanddiametersoftheguiderollersurfacederusting.Derustingmachinetoolsmaincomponentssuchasbed,spindleboxofhorizontallathemainreference,usingtoolssuchaswirebrushonthesurfaceoftheguiderollergrinding,canberemovedbylooseningortiltoftheoxidescale,rust,weldingslag.Keywords:Guideroller；derustingmachineIII目录摘要.IAbstract.II目录.IIICONTENTS.V第1章绪论.-1-1.1课题目的及意义.-1-1.2国内外钢管除锈技术发展概况.-2-1.2.1目前国内外除锈技术分析.-2-1.2.2国内外现有的除锈设备.-6-1.2.3国外除锈设备的新发展.-7-1.3本课题的任务及技术要求.-10-1.3.1课题任务.-10-1.3.2主要技术要求.-10-第2章导辊除锈机床原理及方案设计.-11-2.1导辊除锈机床的原理.-11-2.2导辊除锈机床的方案设计.-11-2.2.1导辊除锈机床的结构设计方案.-12-2.2.2机床主要部件及其运动方式的选定.-12-2.3本章小结.-14-第3章结构设计.-15-3.1主轴箱结构设计.-15-3.2刀架结构.-17-3.3尾座结构设计.-18-3.4溜板箱结构设计.-18-3.5床身结构设计.-19-3.6本章小结.-20-第4章设计校核.-21-4.1主轴V带设计.-21-4.2钢丝刷的计算.-23-4.3蜗轮、蜗杆的设计.-25-IV4.4主轴的设计与校核.-28-4.5轴承的设计计算.-33-4.6滚珠丝杠副选择与校核.-34-4.6.1滚珠丝杠副简介.-34-4.6.2滚珠丝杠副的选择及校核.-35-4.7本章小结.-38-结论.-39-致谢.-40-参考文献.-41-VCONTENTSAbstract.IChapter1Introduction.11.1subjectofthepurposeandsignificance.11.2domesticandforeignsteelpiperustTechniqueDevelopment21.2.1athomeandabroadRustTechnology.21.2.2athomeandabroadblastingequipment.61.2.3blastingequipmentabroad.71.3topics,tasksandtechnicalrequirements101.3.1Thecurriculumtask.101.3.2Themaintechnicalrequirements.10Chapter2Rustremovalmachineprincipleanddesignoftheguideroller.112.1Theprincipleoftheguiderollerrustmachine112.2Designoftheguiderollerrustmachine.112.2.1Guiderollerruststructureofthemachinedesign.122.2.2Machinetoolpartsandtheirmovementpatternselected.122.3Summary14Chapter3StructuralDesign153.1spindleboxdesign.153.2Theturretstructure173.3Tailstockstructuraldesign183.4apron,structuraldesign.183.5bodystructuredesign193.6Summary.20Chapter4Designcheck214.1SpindleVbeltdesign214.2wirebrushcomputing.234.3worm,thewormdesign.254.4Designofthespindleandcheck.284.5bearingdesigncalculation.33
