摘要

本篇设计是汽车用四轮定位举升机液压控制系统设计,主要是通过液压缸来驱动连接杆,而连接杆是说主连杆固接,这样就等于说控制了连杆在升降,而主连杆是一端通过滚轮支撑主大剪台一端是通过销轴固定在大剪台下面,这样就同时带动了大剪台的升降,而大剪台的升降行程与液压缸的行程有直接关系。文章主要介绍了汽车用四轮定位举升机液压控制系统的类型以及结构和液压缸的选型计算等等。车用四轮定位举升机液压控制系统作为液压控制系统的一个重要组成的部分,随时时代的发展和工业的进步,液压工业对其提出了新的要求。车用四轮定位举升机液压控制系统在汽车的维修方面起着重要的作用,它直接影响着汽车维修的工作效率和成本,因此车用四轮定位举升机液压控制系统的设计是当今机械工业发展的必然趋势,在以后的若干年里,也会起到越来越重要的作用。 本次设计是关于车用四轮定位举升机液压控制系统的设计,通过对新式的车用四轮定位举升机液压控制系统的结构和液压方面进行创新设计,使得此种类型的车用四轮定位举升机液压控制系统的使用范围更广泛,在汽车维修领域也会起到越来越重要的作用。

Abstract

For a lot of special places, like the risk is very big, or we are difficult to reach, such as disarm bombs, unknown corresponding domains such as detection, probing deep of more dangerous situation usually need to implement the robot.It’s a main part of robot for micro pedipulator, walking robots and more than six feet, compared to the Eight Legged Robot, because of strong bearing capacity, good stability, which the meritss is simple construction, So, a large number of researchers around the world, start .an important positionin national economy mould technology has also become to measure a national product manufacture level of important symbol.Injection molding plastic molding isan important method .it is mainly suitable for thermoplastic molding .and canbea complicated shape of precision plastic forming parts is the adsl surface hella a design model .

Its principle is diagonal synchronization, leg activity by the structure of the crank rocker, front leg movements around the same, it detailed performance curve characteristics of the connecting rod,when the curve trajectory diagonal straight line segment, the robot is stationary, the motion trajectory when the diagonal curve is slanting line do the walking.
