1、 *大学毕业设计(论文) I 内容提要 气动传动作为一种易于推广普及的实现工业自动化的应用技术，其气源容易获 得，环境污染小，工作速度快，动作频率高，工程容易实现,而PLC是一种功能强， 编程简单、可靠性高的自动化控制产品，二者在工业生产上都得到了广泛的应用。正 是基于以上考虑，为提高生产效率，提高自动化程度，现设计一台基于PLC的全自 动气动钻床，该机床能对工件进行快速定位，夹紧及钻削加工。 本文主要是通过应用机床设计的一般方法对传统机床的机构和控制系统进行设 计及改进。设计的主要内容是普通台式钻床传动系统的改进、送料夹紧系统设计、进 给系统的设计、PLC控制系统的设计和钻床的结构设计等方面
2、，其中重点在于进给 系统、进给系统气压缸的设计和PLC控制系统的设计。气压系统的设计主要是解决 主轴高速旋转与轴向进给两个自由度的实现；PLC控制系统的设计主要是通过应用 PLC控制程序来实现对气压回路的动作控制及钻床加工过程的动作设计。 *大学毕业设计(论文) II Summary As a popular industrial automation technology, the pneumatic drive is easy to spread with advantage easy access to the gas sourse,low environmental pollution
3、,high working speed, high movement frequency and high engineering feasibility. Because PLC is a automation and control products with high function, simple programming and high reliability .Both of them have been widely used in industrial production. It is based on the above considerations,here I am
4、to disign a fully automatic pneumatic drilling machine that based on PLC which can quickly locate,clamp and drill on the the workpiece in order to improve the production efficiency and the degree of automation. This paper is mainly to design and improve the institution of traditional machine tools and control systems through general application of machine tool designing. The main content of the design is ordinary desktop drill transmission system improvement, feeding clamping system design
