The external transfer gripper drives the workpiece to move toward the three-jaw chuck of the active end connecting rod clamping assembly 2-3 until the connecting rod is inside the three-jaw chuck clamping area and then stops.

At the same time, the equipment stops and an audible and visual alarm reminds the operator to manually mark the circular area with a marker pen. After marking, press the start button of the equipment. The equipment continues to work until the entire straight section area of ​​the workpiece is detected. After the detection is completed, the external transfer gripper automatically reaches the top of the ultrasonic flaw detector to clamp the workpiece, and the three-jaw chucks on both sides are released to remove the workpiece.

[0045] After the inner liner of the Type III hydrogen storage bottle is formed, the automatic non-destructive ultrasonic flaw detector accurately controls the movement position of the detection head through the PLC internal program, and cooperates with the servo rotation of the equipment itself to monitor and detect the straight section of the bottle body in real time.
