Online full volume phased array ultrasonic detecting device for wire rods

The invention relates to the field of PAUT phased array ultrasonic nondestructive detection, and especially relates to an online full volume phased array ultrasonic detecting device for wire rods. Thedevice includes a support; the support is provided with a liftable arc-shaped plate; the lower surface of the arc-shaped plate fits with the side surface of a wire rod; the arc-shaped plate is provided with probe installation holes and water injection holes; the device also includes a motor and two first leading screws; the motor drives the two first leading screws to perform co-rotating; and thetwo ends of the two first leading screws are located on the support through bearing pedestals. The full volume ultrasonic detection of the wire rods that rotate while moving forward can be realized by utilizing the two co-rotating leading screws to drive the wire rods to rotate and utilizing nut seats matching the leading screws to push the wire rods to move forward; the rapid detection of multiple wire rods can be realiz
