本科毕业设计 题目名称： 小型双级液压举升器设计 学 院： 专业年级： 学生姓名： 班级学号： 指导教师： 二XXX 年 六 月 十 日 摘 要 目前随着汽车工业的迅速发展，汽车保有量逐渐增多，汽车维修厂和售后服务站不断建立，汽车的维修设备也在不断的更新和完善的过程。虽然现代的先进维修设备给汽车的维修服务带来了极大的方便性，但是传统的维修设备还是非常重要的。这次设计的小型举升器是一种传统的辅助维修设备，它是一种千斤顶的改进型，双级的液压缸构成了它的主要举升部分，柱塞为动力输出部分，还有托盘，底座支撑部分，通过人来踩动踏板，柱塞提供高压的液压油，推动双级活塞进行举升，举升的重物放置在托盘上。本次设计的举升器结构紧凑，占用的面积小，举升的高度高，举升的重量大，工作可靠，便于维修。本文将系统的介绍液压系统的设计，活塞杆直径的选取，结构设计，强度计算等主要参数的计算和系列化设计等方面介绍其设计过程。 dfgsdfget45768@3245ERTIUI#$%#^*^SDFSDHFJsAs中国设备管理网 4aj ith the rapid development of automobile industry, automobile population is gradually increasing in volume, At the same time car repair workshop and service stations are continually established. Vehicle maintenance equipment is also in the process of updated and improved. Although the advanced modern equipment has brought great convenience to the vehicle maintenance services, the traditional maintenance equipment is very important. This design of small lifting is a traditional Auxiliary equipment, which is a jack of improved, and the two-stage hydraulic cylinders constitute its main lifting of the plunger as the driving force of the output. Plunger as the driving force of the output, pallets, formed part of the support base by moving people to stamping on the pedals, the plunger to provide high-pressure hydraulic oil, and promote two-stage piston lift, lift weights placed on pallets On. This design of lifting has a compact structure, occupying little space, lifting the height, weight lifting, reliable, an easy maintenance. This paper introduces the main parameters of calculation and its design process of the hydraulic system design, selected of the diameter of the rod, structural design, calculation of strength and so on .
