摘要 洛阳理工学院毕业设计（论文） PAGE IV PAGE I PLC控制振动送料机 摘 要 本课题题目为：“PLC控制振动送料机” ，阐述了电动液压经轴装卸车的工作原理、整体机构的设计过程并对其液压系统进行了计算和设计。本课题着重叙述液压系统的设计和计算，主要内容有：根据相关要求对各阀类零件的选用；集成块的各零件设计及其装配设计；液压站的装配设计；以及液压缸等部件的设计与计算。本课题采用CAD设计，以及液压系统集成化设计，缩短开发周期、调试周期，易于修改。在设计的过程中根据实际情况取得相关数据，参考有关资料，吸取前人的设计经验，并根据客观实际和掌握的现有知识加以改进，在指导老师的帮助下最终完成对电动液压经轴装卸车的设计与计算。 关键词：经轴装卸车；液压系统；设计计算。 全套图纸加扣 3346389411或3012250582 JingZhou loading and unloading car system Abstract This subject topic is: “Electric hydraulic JingZhou loading and unloading car system”, explain operation principle of the machine which split the nut with hydraulic pressure, whole design process and calculate and design hydraulic pressure system of the machine. whole design process and calculate and design hydraulic pressure system of the machine. The main content included: according to relevant requirements of each valve parts choose; the main content is: integrates one all parts design and assemble designing; the assembly of the hydraulic pressure station is designed; And the design and calculation of such parts as the hydraulic cylinder, etc. This subject design with CAD skill, include the hydraulic pressure system is designed integrated, shortens development period, debugs cycle, because CAD is easy to revise. Obtain relevant data according to the actual conditions during the process of designing, consult relevant materials, draw forefathers design experience, and improve according to the objective reality and existing knowledge grasped, with the help of counselor, I finish design and calculation of the machine which split the nut with hydraulic pressure finally. KEY WORDS: JingZhou loading and unloading car；Hydraulic pressure; Design and calculation. 前言 目　录 TOC \o 1-3 \h \z \u 前　言 1 第1章 液压系统设计 2 1.1 PLC控制的振动送料机液压系统 2 1.1.1 振动下料机的基本结构 2 1.1.2 振动下料机的液压系统图及其工作原理 3 1.1.3技术特点 4 1.1.4 技术参数（见表1-1） 4 第2章 液压缸的设计 6 2.1 液压缸主要尺寸的确定 6 2.1.1 夹紧缸内径D和活塞杆直径d的确定 6 2.1.2 液压缸壁厚和外径计算 8 2.1.3 液压缸的选用及工作行程的确定 9 2.2 各工作阶段液压缸
