Design and Implementation of Control System in Ultrasonic Detection Machine for Plate Part
It is provided that when a machine has some thin-walled monolithic structure parts, It can improve equipment stiffness, reduce the weight of the equipment, greatly reducing equipment parts number. But, the casting property of the thin-walled monolithic structure parts are very bad, at the same time, those parts may have a warp in machining processes. So, to a thin-walled monolithic structure part of an important machine, nondestructive inspection should be carried out before assembly. The machine typically was designed to detect if a plate part has some imperfections. The machine includes control system built with SIEMENS CPU224 programmable logic controller (PLC), hydraulic driving system and the ultrasonic detection, etc. The prototype built can detect a key part before assembled, which is used in military, high pressure vessel and huge bridge.
