毕业设计（论文）摘要作为现代机械设备实现传动与控制的重要技术手段，液压技术在国民经济各领域得到了广泛的应用.与其他传动方式相比较，液压传动具有其独特的技术优势，其应用领域几乎囊括了国民经济各工业部门。本文根据数控铣床的用途﹑特点和要求，利用液压传动的基本原理，拟定出合理的液压系统图，再经过必要的计算来确定液压系统的参数，然后按照这些参数来选用液压元件的规格和进行系统的结构设计。数控铣床的液压系统，外形新颖美观，动力系统采用液压系统，结构简单、紧凑、动作灵敏可靠。本文通过对数控铣床的工况分析,给出了对于一般夹紧装置分析的方法,对于提高制造质量、实际生产具有一定的指导意义。关键词：现代机械；数控铣床；夹紧装置；液压系统设计ABSTRACTAsamodernmachineryequipmentrealizationtransmissionandcontrolofimportanttechnicalmeans,hydraulictechnologyinthefieldofnationaleconomyhasbeenwidelyusedwithothertransmissionway.Comparedwithitsunique,hydraulictransmissiontechnologyadvantage,itsapplicationfieldalmostincludethenationaleconomiceachindustrialsectors.Thisarticleaccordingtotheusage,characteristicsandrequirementsofthepurposesofCNCmillingmachineusesthebasicprincipleofhydraulictransmission,drawsupareasonablehydraulicsystemandundergoesthenecessarycalculationtodeterminetheparametersofhydraulicsystemwhichdeterminetochoosehydrauliccomponentsandsystemstructureofthespecification.ThehydraulicsystemofCNCmillingmachineisnewandoriginalbeautiful,thedrivingforcesystemadoptshydraulicpressuresystemthatmakesthestructuresimpleandcompact,theactionquickandreliable.ThispaperanalyzedtheoperationconditionoftheCNCmillingmachine,andgivestheanalysisforaverageclampingdevicetoimprovethemethod,manufacturingquality,theactualproductionhascertaindirectivesignificanceKeywords：Modernmachinery；CNCmillingmachine；Clampingdevice；Hydraulicsystemdesign目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc295288394"摘要PAGEREF_Toc295288394\hIHYPERLINK\l"_Toc295288395"ABSTRACTPAGEREF_Toc295288395\hIIHYPERLINK\l"_Toc295288396"目录PAGEREF_Toc295288396\hIIIHYPERLINK\l"_Toc295288397"1液压传动的发展状况以及优缺点PAGEREF_Toc295288397\h1HYPERLINK\l"_Toc295288398"1.1国内液压传动的发展状况PAGEREF_Toc295288398\h1HYPERLINK\l"_Toc295288399"1.2国外液压传动的发展状况PAGEREF_Toc295288399\h1HYPERLINK\l"_Toc295288400"1.3液压传动的优缺点PAGEREF_Toc295288400\h1HYPERLINK\l"_Toc295288401"1.3.1液压传动有以下一些优点PAGEREF_Toc2952884
