基于PLC的双面钻孔组合机床监控系统设计
摘 要
本文以双面钻孔组合机床为研究对象，通过分析机床的工作原理和运动形式，结合机床的电气控制要求，设计了以PLC为核心的主控制系统。
硬件方面进行了PLC选型，列出了I/O分配表，并绘制了接线图；软件方面以STEP 7-Micro/WIN32为编程软件编写梯形图并导出指令表；监控方面用组态王设计出组态监控画面实现对机床的实时监控。
将PLC技术应用到机床的电气化控制系统中，提高了机床的加工精度和可靠性，降低了设备故障率，方便了设备的维护，在节约经济成本的同时完全满足了批量生产的要求。

Design of Two-sided Drill Hole Modular Machine Tool Control System
Based on PLC
ABSTRACT
In this paper, two-sided combination drilling machine for the study, through the analysis of the principles and form of exercise to work the machine, combined machine electrical control requirements, the design of the PLC as the core of the main control system.
The PLC hardware aspects of the selection, a list of I/O allocation table and draw a wiring diagram; software in order for the programming software STEP 7-Micro/WIN32 ladder and export instruction sheet; surveillance design with kingview the configuration of the machine's monitor screen to achieve real-time monitoring.
The PLC technology will be applied to the machine control system electrification improves machining accuracy and reliability, reduce equipment failure rate, easy maintenance equipment costs while saving the economy to fully meet the requirements of mass production.
KEY WORDS: PLC, two-sided drilling, combination machine tools, control system, configuration
