毕业设计论文-三级液压缸毕业设计将液压缸提供的液压能重新转换成机械能的装置称为执行元件。执行元件是直接做功者，从能量转换的观点看，它与液压泵的作用是相反的。根据能量转换的形式，执行元件可分为两类三种：液压马达、液压缸、和摆动液压马达，后者也可称摆动液压缸。液压马达是作连续旋转运动并输出转矩的液压执行元件；而液压缸是作往复直线运动并输出力的液压执行元件。而此说明书是针对液压缸的工作环境和工作要求来确定液压缸的工作压力和承载能力，来确定其缸筒内径、壁厚和活塞杆的直径。再根据液压缸的零部件的工作要求确定零件的工艺，根据零件的精度要求确定零件的加工方法，并生成工艺卡片，完成零件的加工。

Abstract
Hydraulic cylinder will be able to provide the hydraulic-mechanical energy conversion device called actuators. Work is a direct implementation of components， from the point of view of energy conversion; it is the role of the hydraulic pump opposite. According to energy conversion in the form of implementation of the three components can be divided into two categories: hydraulic motors， hydraulic cylinders， hydraulic motors and swing， which may also be said swing hydraulic cylinder. Hydraulic motor is the continuous torque and rotational movement of the hydraulic actuators， and hydraulic cylinder is a reciprocating linear motion and the output of the hydraulic components. And this statement is the hydraulic cylinders for the working environment and job requirements of hydraulic cylinders to determine the pressure and work load， to determine the cylinder diameter， thickness and diameter of the rod. According to the hydraulic cylinder parts of the job requirements identified parts of the process， according to parts of the accuracy of determining parts processing methods， and generate process card， complete the processing parts.
