厂修车中,滚动轴承的货车越来越多,由于因RD2车轴轴端三个螺孔造成的探伤盲区,使小角度探头已不能适用于车轴镶入部的超声波探伤。为了消除冷切隐患,我厂采用了大角度探头及贯通探伤的新工艺。设备结构见图1。 该装置可使轮对自由转动到任意位置进行探伤检查。探伤完后,用风动推轮机构将轮对推出。 Plant repair vehicles, rolling stock trucks more and more, due to RD2 axle shaft end of the three screw holes caused by the detection of blind spots, so that the small angle probe has been unable to apply to the Ministry of the axle inlaid ultrasonic testing. In order to eliminate cold hidden trouble, I plant using a large angle probe and penetrating new technology. Equipment structure shown in Figure 1. The device allows the wheel to rotate freely to any position for inspection. After the flaw detection, with the wind push wheel mechanism will wheel out.
