1、摘要组合机床及其0动线是集机电于一体的综合0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,冈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0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屮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A台,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ft睐,它应用多位主轴箱、可换主轴箱、编码随行夾具和刀具的自动更换,配以可编程序控制器(PLC)、数
2、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。木文对可编程序控制器(PLC)应用于双面钻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。通过上位计算机可对机床的现场状态实施监控和对工作参数进行调整,使系统工作在最佳状态。近几年来的现场应用情况表明,该PLC控制系统工作可靠,操作方便,提高了工效。关键词:PLC;组合机床;步进梯形指令(STL)。AbstractCombinationmachinetoolsandautomaticlineisacomprehensivecol
