本科毕业设计论文题目精密倾角计标定平台设计系别机电信息系专业机械设计制造及自动化班级学生学号指导教师2013年04月1精密倾角计标定平台设计摘要测量技术是工业制造的一个重要部分,精密零件制造完毕后都要进行检查,看精度是否达到要求,比如平面的角度,高度等。一般的倾角计很难达到高精度的测量。针对这一情况,本文设计了一款数控倾角计,能够实现三个坐标方向上的自由度。本文中,对数控倾角计标定平台的总体布局、床身的选材、导轨的设计、进给方式的选择做了介绍,选用燕尾型气体静压导轨,同步齿形带传动,摩擦杆进行驱动选用伺服电机作为动力源。最后利用AUTOCAD软件对其整体进行设计绘制。关键词倾角计数控标定平台2AbstractPrecisioninclinometercalibrationplatformdesignAbstractMeasurementtechnologyisanimportantpartofindustrialmanufacturing,precisionpartsmanufacturingaftercheck,lookattheaccuracymeetstherequirement,suchasplaneangle,heightetc..Theinclinometerisdifficulttoachievehighprecisionmeasurement.Inviewofthissituation,thispaperintroducesthedesignofadigitalinclinometer,canrealizethethreecoordinatedirectionsonthedegreesoffreedom.Inthispaper,theNCinclinometerofoveralllayout,bedmaterial,guidedesign,feedingmodeselectionisintroduced,thedovetailtypegasstaticpressureguiderail,synchronousbelttransmission,frictionroddriveservomotoraspowersourceselection.Finally,theoveralldesigndrawingwithAUTOCADsoftware.KeyWordsinclinometerCNCAUTOCAD3目录摘要..............................................................................................................1ABSTRACT....................................................................................................21绪论........................................................................................................11.1前言..........................................................................................................................11.2数控测量仪测量原理..............................................................................................11.3数控倾角计的组成和特点......................................................................................21.4本文主要设计内容及要求......................................................................................22数控倾角计整机机构介绍...................................................................................42.1总体布局...................................................................................................................42.2床身材料选用...........................................................................................................52.3导轨的设计...............................................................................................................62.4进给传动方式的选择...............................................................................................92.4.1进给丝杠...........................................................................................................92.4.2钢丝和钢索传动...............................................................................................92.4.3摩擦驱动.........................................................................................................102.5本章小结.................................................................................................................103数控倾角计的主要零部件的设计...................................................................113.1电机选型.................................................................................................................113.1.1X方向驱动电机选择.....................................................................................123.1.2Y方向驱动电机.............................................................................................133.2带的设计计算.........................................................................................................143.2.1X轴同步带机构的设计计算.........................................................................143.2.2Y同步带机构的设计计算.............................................................................153.3环境控制平台.........................................................................................................1643.3.1温度控制.........................................................................................................163.3.2隔振.................................................................................................................173.4光栅尺的选型.........................................................................................................183.5本章小结.................................................................................................................194测量仪精度分析....................................................................................................214.1测量仪误差源.........................................................................................................204.2测量仪精度分析.....................................................................................................224.2.1测量表的精度.................................................................................................224.2.2数学模型的误差.............................................................................................224.2.3测杆受力引起的误差.....................................................................................234.3本章小结.................................................................................................................235结论.......................................................................................
