数控卧式镗铣床主轴箱用液压平衡机构的设计与分析(开题报告,中期报告,外文翻译,论文说明书15500字,CAD图7张)
摘 要
任何液压系统都是由一些基本回路所组成的,所谓的液压基本回路是指能实现某种规定功能的液压元件的组合。
压力控制回路是控制整个系统或局部油路的工作压力。压力控制回路是利用压力控制阀来控制整个系统或局部油路的压力,达到调压、卸载、减压、增压、平衡、保压、泄压等目的,以满足执行元件对力或力矩的要求。对于液压基本回路的实验装置设计,能使我们更好的掌握也压得基本原理及液压系统设计的基本流程,并且对设计的一般步骤与方法有了更好的掌握。
本文阐述了主轴箱用液压系统使主轴箱向上运动、向下运动、以及停止运动时的平衡压力基本稳定。根据液压原理图以及主轴箱平衡机构装配图对各部分液压元件进行选材校核,从而完成整个设计。论文首先综述了国内外液压技术的研究进展及研究现状、分析课题的研究背景、阐述课题研究的意义和内容。然后重点根据液压原理图,从而选择液压元件,计算其性能是否符合指标,最后在说明液压系统工作时的注意事项。

CNC horizontal boring and milling machine spindle box design and analysis of hydraulic balance mechanism
Abstract
Any hydraulic system is composed of some of the basic circuit of the hydraulic basic circuit, the means to achieve a certain provisions of the hydraulic components functional combination.
Pressure control loop is to control the entire system or local oil pressure of work.Pressure control circuit is a control valve to control the entire system or the local oil pressure, pressure, unloading, achieve decompression, pressure, balance, pressure, pressure relief purposes,in order to meet the requirements of executive component of force or torque. For the design of experimental device of hydraulic basic circuit, will enable us to better grasp the basic process design is the basic principle and the hydraulic system, have a better grasp of design and the general steps and methods.
This paper expounds the main spindle box hydraulic system for the main spindle box moves upward, downward movement, and stop the movement of the basic stability of equilibrium pressure. According to various parts of the hydraulic components of hydraulic schematic diagram material check and balance mechanism of spindle box assembly drawing, thus completing the whole design. The paper first summarizes the analysis of the status quo, and research progress of study on the hydraulic technology at home and abroad and the significance of research background, describes the research topics. Secondly based on the hydraulic principle diagram, thus the selection of hydraulic components, its performance meets the index calculation, the points for attention in the hydraulic system work.
