工业制造领域中对零件加工的要求也越来越高，而激光技术在材料加工行业具有非常明显的优势。激光加工技术与传统技术相互一比，激光加工的优点就十分明显了，如节约材料，对加工对象的某些局限性要求较低，在大批大量生产中大量节约成本。在国外，很多高精密仪器的零件加工，大多数都需要用到激光加工技术。该课题是基于某科研项目来开展的，近年来，已经有很多行业逐渐在使用激光加工工艺，它能够在各种型面上进行雕刻，并且即使图案异常复杂，它也能够满足要求，不仅如此，无论是平面，还是三维立体，都能够通过激光加工来完成，但该工艺对于机械和控制系统有着较为苛刻的要求，本课题的目的就是开展机械传动平台的设计。本文先分析该机械平台所需满足的条件，总体方案定下来之后，对各部件分开进行设计，设计主体是电控旋转台，各轴的直径强度，轴承的寿命等都需要计算。其次是支架尺寸设计，夹具尺寸设计，旋转工作台尺寸设计。最后对该机械平台进行经济和环保性上的分析。关键词机械平台，两自由度，球形件，激光加工，蜗轮蜗杆毕业设计说明书（论文）外文摘要TitleMechanicalPlatformDesignofSphericalLithographySystemAbstractInthefieldofindustrialmanufacturing,therequirementsforpartsprocessingarealsoincreasing,andlasertechnologyhasobviousadvantagesinthematerialprocessingindustry.Theadvantagesoflaserprocessingtechnologyandtraditionaltechnologyareveryobvious.Theadvantagesoflaserprocessingareobvious.Forexample,materialsaving,somelimitationsonprocessingobjectsarerequired,andalargeamountofcostissavedinmassproduction.Inforeigncountries,mostoftheprocessingofpartsofhigh-precisioninstrumentsrequireslaserprocessingtechnology.Thesubjectisderivedfromascientificresearchproject.Laserprocessinghasbeenwidelyusedinvariousindustries.Itcanengraveverycomplicatedpatternsondifferentprofilestomeetdifferentprocessingneeds.Itcanbeplanarorthree-dimensional.Therequirementsformachineryandcontrolsystemsareveryhigh.Thistopicmainlydesignsthemechanicaltransmissionplatform.Thispaperfirstanalyzestheconditionsthatthemechanicalplatformneedstomeet.Aftertheoverallplanisset,thecomponentsaredesignedseparately.Themainbodyofthedesignistheelectronicallycontrolledrotatingtable.Thediameterstrengthofeachshaftandthelifeofthebearingneedtobecalculated.Followedbythebracketsizedesign,fixturesizedesign,rotarytablesizedesign.Finally,themechanicalplatformisanalyzedeconomicallyandenvironmentally.Keywordsmechanicalplatform,twodegreesoffreedom,sphericalparts,lasermachining,wormgear目录1引言.....................................................................................................................................11．1国内外发展趋势...........................................................................................................11．2研究意义.......................................................................................................................22功能设计.............................................................................................................................23方案设计.............................................................................................................................33.1总体方案设计..................................................................................................................33.2电控旋转台方案设计......................................................................................................43.2.1电控旋转台结构设计..................................................................................................
