基于华中数控系统的复合加工机床控制系统

为了提高机身大部件在装配过程中钻孔铆接的效率,并满足高精度制孔要求,设计了由五轴机床和末端执行器组成的自动化协同钻铆控制方案。机床本体及高精度转台采用华中数控系统控制,末端执行器采用倍福PLC程序控制。在明确钻铆需求后设计了基于工业网络的硬件组态和基于多软件平台的软件组态,并利用Microsoft Visual Studio开发平台编写了上位机集成控制软件。控制系统分别采用Ethernet和Ether CAT工业以太网实现上位机控制系统和华中数控系统、倍福PLC控制程序的通信连接。在集成控制软件中通过套接字进行以太网通信接口开发,并在复合加工机床上进行试验验证。该控制系统具有稳定性好、集成度高、响应快、效率高的特点,能够满足钻铆需求。

Control System of Combined Machining Machine Tool Based on Huazhong Numerical Control System

In order to improve the efficiency of drilling and riveting in the assembly process of large fuselage parts and meet the requirement of high precision drilling,a collaborate control scheme of auto-drilling rivet system composed of five-axis machine tool and end-effector is designed.The machine tool and high precision turntable are controlled by Huazhong numerical controller and the end-effector is controlled by the PLC program of Beckhoof.After making clear the drilling and riveting demands,the hardware configuration is designed based on industrial network and software configuration is designed based on multi-software platform.And the integrated control software of the host computer is written using Microsoft Visual Studio.The connection of the host computer control system with Huazhong NC system and Beckhoof PLC employs the Ethernet and EtherCAT,respectively.The development of Ethernet interface in the integrated control system uses Socket and some experiments on the combined machining machine tool are conducted.The control system has many advantages as follows:good stability,high integration,fast response and high efficiency,which can meet the requirements of drilling and riveting.
