航天异形紧固件加工多工位机床的控制系统设计

Control design of multi-station machine tool for aerospace special-shaped fastener processing

  • 摘要: 针对航空航天领域某异形紧固件内孔生产工序分散、加工效率和加工精度低、加工成品一致性差,设计开发出以ZMC406运动控制器为控制核心的多工位专用机床。该机床由机械结构、气动系统和电气控制系统组成。文章主要阐述了控制系统的总体要求、各个控制系统模块、控制系统的软硬件设计。通过工控一体机触摸屏以EtherCAT为通讯协议对机床加工动作的控制和加工参数的设置,实现了异形紧固件内孔的集中化、自动化加工。机床实际加工试制结果表明机床生产节拍为8 pcs/min,合格率在99%以上,提高了该异形紧固件的加工精度和效率,产品一致性较好,在航天异形紧固件生产制造领域具有一定应用推广价值。

     

    Abstract: Aimed at the problems of process dispersion, low processing efficiency and precision,and poor consistency of finished products in the production of inner hole of special-shaped fasteners in the aerospace field,a multi-station special machine tool with ZMC406 motion controller as the control core is designed and developed.The machine tool is made up of mechanical structure,pneumatic system and electrical control system.The general requirements of the control system, each control system module, software and hardware design of the control system are described.Through the touch screen of the integrated industrial control machine with EtherCAT as the communication protocol to control the machining action of the machine tool and set the processing parameters, the centralized and automatic processing of the inner hole of the special fastener is realized.The actual processing and trial production results of the machine tool show that the production cycle of the machine tool is 8 pcs/min, and the pass rate is more than 99%. The machining precision and efficiency of the special-shaped fastener are improved, and the product consistency is good. Certain application and promotion value is included in the manufacturing field of aerospace special-shaped fastener.
