The invention discloses an ultrasonic flaw detector for a hollow axle. The ultrasonic flaw detector comprises a frame, an axle detection mechanism and a cantilever mechanism, the cantilever mechanism comprises an adjusting assembly, the adjusting assembly comprises a first sleeve, a second sleeve, a third sleeve, a spring, an adjusting rod and a hanging block, the second sleeve is arranged in the first sleeve, the third sleeve is arranged in the second sleeve, the spring is located in the third sleeve, the adjusting rod is partially arranged in the third sleeve, and the spring is arranged on the adjusting rod in a sleeving mode. The lower end of the adjusting rod extends out of the third sleeve and is connected with a hanging block, and the hanging block is connected with an axle detection mechanism. And by arranging the three sleeves, the adjusting stroke is increased, so that the applicable height range of the ultrasonic flaw detector for the hollow axle is wider. By pushing the adjusting rod, the second sleeve and the third sleeve stretch out and draw back synchronously along with movement of the adjusting rod, so that fine adjustment of the vertical height of the axle detection mechanism is achieved, more detection requirements can be met, and the detection efficiency is high.
本发明公开了一种空心车轴超声波探伤机,其包括车架、车轴检测机构和悬臂机构;悬臂机构包括调节组件,调节组件包括第一套筒、第二套筒、第三套筒、弹簧、调节杆和吊块,第二套筒设置在第一套筒的内部,第三套筒设置在第二套筒的内部,弹簧位于在第三套筒的内部,调节杆部分设置在第三套筒的内部,弹簧套设于调节杆,调节杆的下端从第三套筒伸出,并与吊块连接,吊块与车轴检测机构连接。通过设置三节套筒,增大了调节行程,使得该空心车轴超声波探伤机所适用的高度范围更加广泛。通过推动调节杆,第二套筒和第三套筒随着调节杆的移动同步伸缩,从而实现对车轴检测机构的竖向高度的微调,能够满足更多的检测需求,检测效率高。
