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,然后根据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,动力系统采纳液压系统,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ABSTRACTAs a modern machinery equipment realization transmission and control of important technical means, hydraulic technology in the field of national economy has been widely used with other transmission way. Compared with its unique, hydraulic transmission technology advantage, its application field almost include the national economic each industrial sectors.This article according to the usage, characteristics and requirements of the purposes of CNC milling machine uses the basic principle of hydraulic transmission, draws up a reasonable hydraulic system and undergoes the necessary calculation to determine the parameters of hydraulic system which determine to choose hydraulic components and system structure of the specification. The hydraulic system of CNC milling machine is new and original beautiful, the driving force system adopts hydraulic pressure system that makes the structure simple and compact, the action quick and reliable. This paper analyzed the operation condition of the CNC milling machine, and gives the analysis for average clamping device to improve the method, manufacturing quality, the actual production has certain directive significanceKey words:Modern machinery;CNC milling...
