摘　　要：用于加工深孔的钻床多采用继电器和液压结合的方法,该加工系统需要大量的硬件接线,可靠性低,同时钻头速度和机床进给速度单一且不能相互有效配合,对不同硬度材质钻孔的效率不高。基于此,提出以PLC和变频器相结合的控制系统,采用分段进给和变频可以有效解决这些问题,同时可以根据需要通过扩展模块实现一台PLC控制多个钻孔单位,满足大规模工业生产的需要。Drilling deep hole machining for multi-use relays and hydraulic combination of methods, such a system requires a lot of hardware wiring, low reliability, Meanwhile drill speed and machine feed rate single and can not be effective co-ordination, drilling efficiency of different hardness materials is not high. with the combination of PLC and inverter control system. Use segmented feed and frequency conversion can effectively solve these problems.At the same time it can be achieved as required by the extension of a PLC to control multiple drilling units to meet the needs of large-scale industrial production.
