摘 要: | 针对复合螺栓搓丝模板的成型特点,引入闭环控制系统对液压缸的位移、压力进行实时动态调节,首先设定位移、压力值,其次对传感器采集的数值与设定值比较,二者的偏差经PID算法调节后送入比例放大器调节比例阀的开度,以控制液压缸的动作,最后利用CAN总线将传感器采集的实时数据传输至触摸屏,实现位移、压力等数据的实时显示。通过现场调试及生产应用,实现了复合螺栓搓丝模板表面在同一水平面上,用该模板加工而成的复合螺栓的螺纹牙底在同一圆柱面上,复合螺栓具有较好的可旋合性与防松可靠性。

Abstract: | According to the formation characteristics of composite bolt twist wire tem -plates, closed loop control system was introduced to real-time control the displacement andpressure of the hydraulic cylinder. First of all, displacement and pressure values were set; then the values collected by the sensors were compared with the preset ones and the devia -tion is sent to the proportional amplifier after adjustment by PID algorithm to regulate theopening of proportional valve and in turn to control the action of hydraulic cylinder; finally,the real-time sensor data is transmitted to the touch screen by the CAN bus, realizing real-time display of displacement and pressure. Through on-site test and production application, itis achieved that the surface of the composite bolt twist wire templates on the same horizontalplane and the thread bottom of composite bolts processed by the templates are on the same cylindrical surface, which proves the composite bolt has good screwing property and anti-loos -ening reliability. |
