Ultrasonic detection box for shaft rod

The invention discloses an ultrasonic detection box for a shaft rod. The ultrasonic detection box comprises a box body. Openings are arranged on both sides of the box body for a conveyor belt to move. An ultrasonic wave detector is arranged on the upper end in the box body. Symmetric clamps are arranged on the conveyor belt to arrange and fix the shaft rod. A rotating disc is arranged on each clamp to drive the rotation of the shaft rod. A position sensor is arranged in the box body. The position sensor is connected with the ultrasonic wave detector. The rotating discs are electrically connected with the ultrasonic wave detector. The thickness of the protection layer on the surface of the shaft rod is detected by ultrasonic wave. The ultrasonic detection box provided by the invention has the advantages of simple structure and convenient operation. The detection quality and efficiency of the shaft rod are improved. 本发明公开了种轴杆的超声波检测箱，包括有箱体，在所述箱体的两侧设置有开口供运输带移动，所述箱体的内部上端设置有超声波检测器，所述运输带上设置有对称的夹具用来安装固定轴杆，并在夹具上设置有旋转盘
