机械液性塑料心轴夹具设计及分析

内蒙古科技大学本科生毕业设计说明书题目：液性塑料心轴夹具设计及分析学生姓名：学号：专业：机械设计制造及自动化班级：机械06-8班指导教师：内蒙古科技大学毕业设计说明书I液性塑料心轴夹具设计及分析摘要心轴定位是机械加工中常见的一种定位方式，广泛应用于车、铣、钻、磨等工序中，主要应用于要求以内孔为定位基准，并保证外圆轴线和内孔轴线的同轴度要求或者螺栓孔对于中心孔有位置度要求的情况。本设计将以加工轴套类零件外表面为例来对塑料心轴进行设计与制造，并对其夹紧力进行分析，使其能准确的夹紧工件，实现高精度加工液性塑料定心夹紧机构是弹性定心夹紧机构的一种,是适应近年来机械行业对零件的高精度要求出现的，效率高且极大的降低了成本.它以液性塑料作为介质，利用其不可压缩性,可以将压力均匀地传递给薄壁套筒或滑柱,使薄壁套筒或滑柱产生均匀的径向弹性变形或位移而将工件定位和夹紧.液性塑料定心夹紧机构的优点在于定心精度高,其定心精度一般可以达0.005mm～0.01mm,最高达0.001mm,同轴度可达0.01mm～0.02mm.另外还用于多位夹紧,其夹紧迅速,夹紧力大且可靠.但对目前现在存在的各种局限性也做了相关例举。……………………………全套图纸，加153893706关键词:液性塑料；薄壁；高精度；心轴；夹具；弹性变形内蒙古科技大学毕业设计说明书IIThefixturedesignandanalysioftheliquidplasticsAbstractThelocationisamechanicalinacommonalignment,itiswidelyusedincars,innovation,andwornforimplementation,themainapplicationforapositiontowithinabenchmarkandmakesurethattheoutercircleofaxesandtheaxisoftheholeintherequestorboltholeinthecenterofagoodlocationfortherequirements.Thisdesignwillbeprocessedthepartsoftheexternalsurfaceoftypeofplasticmadetothedesignandmanufacture,andanalysis,theforcetobeprecisegrip,highprecisionworktotheheartofplasticsprocessingbetweentheagency'sauthoritycentringbetweena,inrecentyearsmachineryindustrytothepartsofhigh-precisiondemand,highefficiencyandreducethecostofgreat。Withthefluidnatureoftheplasticforamedium,usingitscompressibility,youcannotbeevenlyontoatubeortravellerunwieldilyflimsy,orslidecolumnsthatareunwieldilyflimsysetitproduceseventheradialdisplacementcompliancesorandaligningworkpiecesandgrip.Liquidplasticbetweensexualheartofheartishighprecision,theheartofthegeneralcan0.005mm～0.01mm,upto0.001mm,coaxialdegreesof0.01mm～0.02mm.alsousedformoregripandtheclampingforcefastandreliable.butnowtherearevariouslimitationsandtherelevantcases.…………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………。Keywords:thenatureoftheplastic；thin-wall；highaccuracy；spindle；fixture；elasticdeformation内蒙古科技大学毕业设计说明书III目录摘要....................................................................................................................................IAbstract.....................................................................................................................................II第一章概述...............................................................................................................11.1液性塑料夹具的研究背景.......................................................................................11.2液性塑料夹具的工作机理.......................................................................................21.3液性塑料夹具的特点及应用...................................................................................31.3.1液性塑料夹具的特点：.................................................................................31.3.2液性塑料夹具的应用：.................................................................................31.4液性塑料心轴的具体应用及其实际过程...............................................................41.5设计步骤...................................................................................................................51.5.1设计研究内容.................................................................................................51.5.2设计预期目标.................................................................................................51.5.3设计方法和路线.............................................................................................5第二章液性塑料心轴夹具的结构设计.................................................................................62.1采用液性塑料心轴的定位夹紧方案.........................................................................62.2薄壁套筒的设计..........................................................................................................72.2.1薄壁套筒的结构...............................................................................................72.2.2薄壁套筒材料的选用.....................................................................................82.2.3薄壁套筒参数设计.........................................................................................82.2.4套筒的夹紧力及产生的力矩【2】..................................................................162.3心轴基体的设计.....................................................................................................172.4加压螺钉和滑柱的设计.........................................................................................182.4.1加压螺钉.......................................................................................................182.4.2滑柱.................................................................................................................192.4.3加压螺钉与滑柱的设计...............................................................................19内蒙古科技大学毕业设计说明书IV第三章液性塑料心轴的制造和使用.............................................................................223.1液性塑料心轴的制造工艺.......................................................................................223.1.1薄壁套筒的制造工艺.....................................................................................223.1.2心轴基体的制造工艺.................
