摘要I數(shù)控臥式鏜銑床主軸箱用液壓平衡機構的設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，達到調壓、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計，能使我們更好的掌握也壓得基本原理及液壓系統(tǒng)設計的基本流程，并且對設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構裝配圖對各部分液壓元件進行選材校核，從而完成整個設計。論文首先綜述了國內外液壓技術的研究進展及研究現(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，最后在說明液壓系統(tǒng)工作時的注意事項。關鍵詞: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)控機床的發(fā)展.21.4液壓技術.41.4.1液壓技術的現(xiàn)狀及其發(fā)展.41.4.2液壓技術的特點.52主軸箱液壓平衡系統(tǒng)的總體設計.62.1主軸箱用液壓平衡機構的簡要分析.62.2負載分析.102.2.1工作負載.102.2.2摩擦負載.102.2.3慣性負載.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防止雜質侵入.202.4.5吸油管與回油管.202.4.6液面指示.212.4.7液壓
