汽车发动机翻转架是一种汽车修理和保养单位常用的设备，广泛应用于轿车等小型车的维修和保养。目前，全国生产翻转架的厂家较多，生产的翻转架的形式也比较繁多，本文介绍了发动机翻转架国内外现状以及发展趋势，在确定了所要设计的翻转架方案之后，即针对翻转架的结构及其特点要求进行了设计与说明，同时对翻转架设计过程中所涉及到的工艺性问题进行补充说明。然后对立柱的强刚度和托臂的强度进行了校核验算。

   本课题所设计的是蜗杆传动360°任意角翻转锁止的发动机翻转架。它的特点是：1、性能可靠，操作方便；2、结构简单；3、拖脚的最低位置低，使得车辆的底盘可以比较低，对各种车辆的适应性扩大了；4、利用蜗杆传动可360°任意角度翻转锁止；5、价格低廉，拥有的市场份额较大。

 

 

    The car engine flip frame is an automobile repair and maintenance units commonly used equipment, widely used in the repair and maintenance of cars and other small cars. Currently,more manufacturers of production flip, flip frame in the form of production is also more diverse, this paper introduces the domestic and international status and development trend of engine flip,flip scheme requirements for the design and description, flip the frame structure and characteristics of supplement flip the aircraft design process involved in the process. Checking checking and then on a column of strong stiffness and the strength of the corbel.
     This topic is a worm drive 360 ° flip lock the engine at any angle flip racks. It is characterized by: 1.reliable, easy to operate; 2.the structure is simple; 3.the dragging feet of the lowest low, making the vehicle chassis can be relatively low, and adaptability to a variety of vehicles to expand; 4. the worm drive can be  360° at any angle flip lock; 5.low prices have a larger market share.
