毕业设计（论文）-PROE油缸实体造型设计.doc

摘要
启闭机用于各类大型给排水、水利水电工程。用于控制各类大、中型铸铁闸门及钢制闸门的升降达到开启与关闭的目的。启闭机按照类型分为液压启闭机,卷扬启闭机,门机,手轮启闭机,手摇启闭机,螺杆式启闭机等。液压启闭机由于在设计和制造方面存在精度和用料等方面的限制,故现在基本上采用三维绘图软件设计和装配液压启闭机的各部分零件,随着三维绘图技术的不断完善和成熟,三维技术在工程件检修和设计方面起到了举足轻重的作用。Pro/E即为一款三维绘图软件,在目前的三维造型软件领域中占有着重要地位,并作为当今世界机械CAD/CAE/CAM领域的新标准而得到业界的认可和推广,是现今最成功的CAD/CAM软件之一,得到了大众的认可。
本论文主要介绍如何利用Pro/E软件对液压启闭机油缸的各部分零件进行绘制并装配成实体。通过对CAD二维图纸的分析、查阅相关资料之后,通过Pro/E软件中的零件模块和装配模块分别对零件进行设计和将零件组合成完整的实体,运用到的主要设计方法多种多样,如运用旋转特征对圆盘类和圆柱类等具有单一对称轴的圆形零件进行操作。设计中综合运用机械设计基础、机械制图、机械制造基础,在Pro/E搭建的平台上对液压启闭机进行全方位的设计和装配,并可以通过对装配体的修改达到二次开发的效果。

Abstract
Hoister are used for all kinds of large Water and Wastewater Engineering, water conservancy and hydropower for controlling all kinds of big, medium-sized iron gates and steel gate lifting which can achieve the purpose of opened and closed. Hoist according to type into hydraulic hoister, roll Yang hoister, door machine, the handwheel hoister, hand operated hoister, screw headstock gear. Because of the hydraulic hoister existing a limit in design and manufacture of precision and materials etc, so now basically used 3-d graphics software design and assembly of the hydraulic hoister each the 3d drawing technology ing perfect and mature, 3d technology palyed a pivotal role in the engineeringof a repair and design area. Pro/E namely as a super 3d drawing software, the three-dimensional modeling software occupies an important position field, and as the world mechanical CAD/CAE/CAM domain the new standards and have been recognized and promotion, is now the most essful one of CAD/CAM software, got public recognition.
This thesis mainly describes how to use the software Pro/E plete each parts of oil cylinder drawing and assembling into entity. Through the analysis of two-dimensional drawing by CAD, access relevant information , useing the parts module and assembly software design of Pro/E for parts modules and parts assembled plete entities, applied to the main design vari
