毕业设计（论文） 课 题 名 称 螺旋千斤顶结构设计及运动仿真 学 生 姓 名 学 号 1141402015 系、年级专业 魏源国际2011级 11机械设计制造及自动化 指 导 教 师 职 称 讲 师 二0一五年五月 内容提要 千斤顶是一种起重高度比较小的简单起重设备。主要用于厂矿、交通运输、企业等部门。其结构轻巧坚固、灵活可靠、方便操作。千斤顶是用刚性顶举件作为工作装置，通过顶部托座或底部托爪在小行程内顶升重物的轻小起重设备。而螺旋千斤顶是千斤顶中最小的种，体积小方便携带，造价低，在日常生活中被广泛应用。 螺旋千斤顶也是一种最简单的机械传动，主要由螺杆、手柄、底座、螺套、旋转杆、挡环、托杯等零部件组装而成的。本文主要分析螺旋千斤顶工作原理的基础上，研究其组成，根据螺旋千斤顶的承载需求，计算螺杆、螺纹等关键件的承载及受力分析；并利用CAD软件及三维造型软件对其进行二维及三维设计。最后利用SOLIDWORKS软件对设计的螺旋千斤顶进行运动模拟仿真。 本文从螺旋千斤顶的零部件的设计与选材等多方面，阐述了它设计的全过程。结合产品设计需求和理论计算公式，最终完成了该产品的设计。 Abstract Jack is a lifting height is relatively small and simple lifting equipment. Mainly used for industrial, transportation, business and other departments. The structure is light and durable, flexible and reliable, convenient operation. Jack is made of rigid top lifts as a working device, through the bracket at the top or bottom bracket claws in the short distance in lifting weights in the light small lifting equipment. The screw jack is Jack in the smallest one, small volume and convenient carrying, low cost and in daily life is widely used.Screw jack is a most simple mechanical transmission, which is mainly composed of a screw, a handle, a base seat, screw sleeve, rotary rod, a baffle ring, a supporting cup components assembled. This paper mainly analyzes the screw jack working principle based on its composition, according to screw jack load demand calculated screw, screw thread of the key parts of the load and stress analysis; and the use of CAD software and 3D modeling software for the A two-dimensional and three-dimensional design. The last screw jack of motion simulation by using SOLIDWORKS software. This article from th
