摘要I數(shù)控臥式鏜銑床主軸箱用液壓平衡機(jī)構(gòu)的設(shè)計與分析摘要任何液壓系統(tǒng)都是由一些基本回路所組成的，所謂的液壓基本回路是指能實現(xiàn)某種規(guī)定功能的液壓元件的組合。壓力控制回路是控制整個系統(tǒng)或局部油路的工作壓力。壓力控制回路是利用壓力控制閥來控制整個系統(tǒng)或局部油路的壓力，達(dá)到調(diào)壓、卸載、減壓、增壓、平衡、保壓、泄壓等目的，以滿足執(zhí)行元件對力或力矩的要求。對于液壓基本回路的實驗裝置設(shè)計，能使我們更好的掌握也壓得基本原理及液壓系統(tǒng)設(shè)計的基本流程，并且對設(shè)計的一般步驟與方法有了更好的掌握。本文闡述了主軸箱用液壓系統(tǒng)使主軸箱向上運動、向下運動、以及停止運動時的平衡壓力基本穩(wěn)定。根據(jù)液壓原理圖以及主軸箱平衡機(jī)構(gòu)裝配圖對各部分液壓元件進(jìn)行選材校核，從而完成整個設(shè)計。論文首先綜述了國內(nèi)外液壓技術(shù)的研究進(jìn)展及研究現(xiàn)狀、分析課題的研究背景、闡述課題研究的意義和內(nèi)容。然后重點根據(jù)液壓原理圖，從而選擇液壓元件，計算其性能是否符合指標(biāo)，最后在說明液壓系統(tǒng)工作時的注意事項。關(guān)鍵詞:主軸箱；液壓平衡系統(tǒng)；平衡液壓缸。AbstractIICNChorizontalboringandmillingmachinespindleboxdesignandanalysisofhydraulicbalancemechanismAbstractAnyhydraulicsystemiscomposedofsomeofthebasiccircuitofthehydraulicbasiccircuit,themeanstoachieveacertainprovisionsofthehydrauliccomponentsfunctionalcombination.Pressurecontrolloopistocontroltheentiresystemorlocaloilpressureofwork.Pressurecontrolcircuitisacontrolvalvetocontroltheentiresystemorthelocaloilpressure,pressure,unloading,achievedecompression,pressure,balance,pressure,pressurereliefpurposes,inordertomeettherequirementsofexecutivecomponentofforceortorque.Forthedesignofexperimentaldeviceofhydraulicbasiccircuit,willenableustobettergraspthebasicprocessdesignisthebasicprincipleandthehydraulicsystem,haveabettergraspofdesignandthegeneralstepsandmethods.Thispaperexpoundsthemainspindleboxhydraulicsystemforthemainspindleboxmovesupward,downwardmovement,andstopthemovementofthebasicstabilityofequilibriumpressure.Accordingtovariouspartsofthehydrauliccomponentsofhydraulicschematicdiagrammaterialcheckandbalancemechanismofspindleboxassemblydrawing,thuscompletingthewholedesign.Thepaperfirstsummarizestheanalysisofthestatusquo,andresearchprogressofstudyonthehydraulictechnologyathomeandabroadandthesignificanceofresearchbackground,describestheresearchtopics.Secondlybasedonthehydraulicprinciplediagram,thustheselectionofhydrauliccomponents,itsperformancemeetstheindexcalculation,thepointsforattentioninthehydraulicsystemwork.AbstractIIIKeyWords：robotarm；harmonicdrive；structuredesign.畢業(yè)設(shè)計（論文）IV目錄1緒論.11.1數(shù)控鏜銑床概述.11.2主軸箱以及液壓系統(tǒng)簡介.11.3數(shù)控機(jī)床的發(fā)展.21.4液壓技術(shù).41.4.1液壓技術(shù)的現(xiàn)狀及其發(fā)展.41.4.2液壓技術(shù)的特點.52主軸箱液壓平衡系統(tǒng)的總體設(shè)計.62.1主軸箱用液壓平衡機(jī)構(gòu)的簡要分析.62.2負(fù)載分析.102.2.1工作負(fù)載.102.2.2摩擦負(fù)載.102.2.3慣性負(fù)載.102.3液壓缸主要參數(shù)確定.112.3.1初選液壓缸的工作壓力.112.3.2計算液壓缸的尺寸.122.3.3液壓平衡系統(tǒng).122.4平衡液壓缸的設(shè)計.142.4.1液壓缸的組成.142.4.2平衡液壓缸的計算.152.4.3平衡液壓缸與主軸箱的連接.192.4.4防止雜質(zhì)侵入.202.4.5吸油管與回油管.202.4.6液面指示.212.4.7液壓
