摘 要

机床作为机械制造业最为普遍的生产工具，其重要性不言而喻。传统机床的应用，很大程度上仍然是依靠人工劳动，对操作者机床操作的熟练性要求较高。零件生产过程中，残次产品的产出率较高，精度、粗糙度等参数不易控制。而且传统机床安全隐患较高，发生劳工伤害的案例比比皆是。然而，伴随着计算机技术的飞速发展，计算机技术和机床二者结合，使传统机床发生了质的变化。从第一台数控机床的诞生开始，到如今近半个世纪的发展，数控机床技术日臻成熟，派生出多种多样贴合生产的专用数控机床。

本文以阀体零件的多工位专用数控机床为研究对象，在充分理解机床结构，熟悉机床工作原理的基础上，选择合理相关参数实现该机床的零部件计算与设计。确定相关零部件尺寸后，依靠pro/e软件来实现零部件的绘制和专用数控机床实体的组装。通过此次设计，加深了对于专用数控机床的认识的同时也学习了一门新的计算机绘图软件，总体上说是收获良多的。

Body parts of the multi-station CNC machine tools design

ABSTRACT

Machinery manufacturing machine as the most common means of production, and its importance is self-evident. Application of conventional machines, still largely rely on manual labor, the higher the operator machine operator proficiency requirements. Parts production process, high yield defective products, precision and roughness parameters difficult to control. Traditional tools and high security risks, the occurrence of labor injury case everywhere. However, with the rapid development of computer technology, computer technology and machine tools combination of both, the traditional machine has undergone a qualitative change. From the birth of the first CNC machine tools began, but now nearly half a century of development, CNC technology matured, derived from the production of a variety of bonding special CNC machine tools.

In this paper, the body parts of multi-station special machine tools for the study, a full understanding of the machine structure, familiar with the working principle of the machine, based on the relevant parameters to achieve a reasonable choice parts calculation and design of the machine. After determining the size of related parts, rely on pro / e software to achieve the assembly drawing and special machine tools entity components. Through this design, deepened the understanding of the special machine tools, while also learning a new computer graphics software, generally speaking, a lot of the harvest.
