卧式双面扩孔组合机床电气控制系统设计 摘 要 组合机床及其自动线是集机电于一体的综合自动化程度较高的制造技术和成套工艺装备。它的特征是高效、高质、经济实用，因而被广泛应用于工程机械、交通、能源、军工、轻工、家电等行业。我国传统的组合机床及组合机床自动线主要采用机、电、气、液压控制，它的加工对象主要是生产批量比较大的大中型箱体类和轴类零件，完成钻孔、扩孔、铰孔，加工各种螺纹、镗孔、车端面和凸，在孔内镗各种形状槽，以及铣削平面和成形面等。随着技术的不断进步，一种新型的组合机床——柔性组合机床越来越受到人们的青睐，它应用多位主轴箱、可换主轴箱、编码随行夹具和刀具的自动更换，配以可编程序控制器（PLC）、数字控制（NC）等，能任意改变工作循环控制和驱动系统，并能灵活适应多品种加工的可调可变的组合机床。 本文对可编程序控制器（PLC）应用于双面孔组合机床电气控制系统的设计思想作了介绍。对系统的硬件组成和软件设计作了较为详细的阐述。PLC）,组合机床,步进梯形指令(STL)Abstract  Combination machine tools and automatic line is a comprehensive collection and integration of high degree of automation in the manufacturing technology and process equipment packages. It is characterized by highly efficient, high quality, economical and practical, they have been widely used for mechanical engineering, communications, energy, industry, light industry, and home electrical appliances industry. Our traditional combination machine tools and machine tool portfolio automatically routes primarily use machines, electricity, gas, hydraulic control, and its processing is targeted at the production lot larger-and medium-bold type and Zhou Lei parts and complete drilling, reaming, cut Kong, the processing of thread, boring, cars carry noodles and protrude Taiwan in Conedera smooth-bore various shapes shafts and horizontal Xianxiao and shape face. As technology advances, a new portfolio of machine tools -- soft combination machine tools increasingly been favored, it applied a line box, convertible main boxes, coding and cutlery accompanying jig automatic replacement, coupled with programmable controller (PLC), numerical control (NC), to arbitrarily change the work cycle control and drive systems, and the flexibility to adapt to the multi-species processing scale variable portfolio tools.  This article mainly introduces the design thought of PLC applying for Modular Machine Tool electronic control system. It gives a detailed statement on the components of the system hardware and design of software. Key words: PLC
