发动机活塞自动安装系统设计摘要随着社会的发展，自动安装技术是现代工业生产中的重要组成，它体现了一个国家的工业重点技术发展水平，它高效的实现人工操作所不能完成的一些工作，解决人工操作的一些弊端，提高生产效率，增加了效益，减少了错误的几率。在这次毕业设计中,传动机构采用了滚珠丝杠来完成水平的运动。夹具部分采用了缓冲较小，易于控制的液压缸控制。导向机构采用直线滚动导轨来完成。控制部分是运用了步进电动机。导向装置是用来支撑和导向的，为各个机械系统中运动装置能到安全、准确的完成其特定方向的运动提供安全保障。直线滚动导轨的接触面之间放置滚珠，帮助两导轨间的相对运动。但这种导轨摩损小，寿命大，定位精度高，灵敏度好，运行平稳可靠，但对尺寸精度要求很高，抗振性不好，保护要求较高。本次设计完成了横向和纵向两自由度的活塞自动安装。关键词自动安装、传动、导向AbstractAutomaticinstallationtechnologyreflectsthelevelofdevelopmentofacountry'sindustrialtechnology,Iteffectivelysolvesthedrawbacksofmanualandimprovingtheefficiencyandreducingtheerrorrate.Inthisdesignprocess,widelyusedforcontrollingasteppingmotor.Bufferclamppartissmallandeasilytocontrolthehydrauliccontrolcylinder.Controlprogramusingmicrocontrollerassemblylanguage.Ballscrewmechanicaltransmissioniscompletedhorizontal,verticalmovement.Mechanicalguidemechanismuseslinearmotionguidetocomplete.Guidingroleistosupportandguidedeviceformechanicalsystemscaneachmovementmeanstosecurecomplete,accuratemotionofitsspecificdirectiontoprovideprotection.Placetheballbetweenthelinearguiderailrollingsurface,toachievetwoslidingrailswithoutrelativemotion.Thisrailwear,highlifelarge,positioningaccuracy,sensitivity,smoothandreliableoperation,buthighergeometricprecision,vibrationandpoor,highprotectionrequirements.Twodegreesoffreedomaredesignedfortheautomaticinstallationofhorizontalandverticalpistons.Keywords:Automaticinstallation,Transmission,Guiding目录1前言...............................................................................................................................................................11.1课题来源及研究的目的和意义..........................................................................................................11.2国内外研究发展现状..........................................................................................................................11.3设计任务..............................................................................................................................................12总体设计方案和电机的选择.......................................................................................................................22.1总体设计..............................................................................................................................................22.2步进电动机的选择计算......................................................................................................................33传动系统设计...............................................................................................................................................93.1传动系统概述......................................................................................................................................93.2齿轮传动设计....................................................................................................................................103.3齿轮回差及其控制..................................
