飞机襟翼铣切设备一键式全气动控制系统设计

针对飞机襟翼与滑轨座对接面铣切设备的平面自动进给问题,提出了通过一键式全气动控制系统实现自动进给、限位停止和自动复位的控制方法。根据刀具路径规划,在需要换向的地方设置机碰换向阀,在零点和终点设置限位开关。通过设置多种控制信号的优先级关系,有序控制平面内X向和Y向行走气马达的正转、反转和停止,自动按照规划路径完成对接面加工。实验结果表明:该一键式全气动控制系统性能稳定,反应敏捷,能准确地自动实现平面自动进给、停止和复位,满足生产技术要求。

Design of One-Key All Pneumatic Control System for Aircraft Flap Milling Equipment

Aimed at the automatic movement problem of the milling equipment for the joint plane of the aircraft flap and slide block, a control method of automatic feed, limit stop and automatic reset is presented through a one-key all pneumatic control system. According to the tool path planning, a control switch is set at the place where the commutation is required, and limit switches are set at the zero and the end points. By setting the priority of various control signals, we orderly control the forward rotation, the reverse rotation and the stop of X-direction and Y-direction walking gas motors in the plane, and make the system complete the milling of the joint plane automatically as the planned path. The experimental results show that the one-key all pneumatic control system has stable performance and quick response, which can automatically realize the automatic feed, the stop and the reset of the plane to meet the production technical requirements.
