Abstract

一种机车车辆车轮轮辐缺陷超声波检测装置,其超声波探头包括四对单发、单收的探头及六个收发一体的探头。四对探头中每个探头的发射角或接收角均为15~33°,扭转角为5~35°,各对探头按设定位置排列;六个收发一体探头中:二个直探头,分别设置在滚动圆的两侧,与滚动圆的轴向距离为1-8mm;二个斜探头,其发射角与滚动圆面平行,距离滚动圆的轴向距离为1-8mm;二个发射角为0~10°的探头,分别设置于滚动圆旁的两侧,且与滚动圆的轴向距离均为1-4mm。该装置能够对各类车轮轮辐的缺陷进行全方位的检测;检测过程不需人工参与,检出率高;检测方法简单,检测结果可靠。
The invention relates to an ultrasonic testing device of a wheel spoke of an engine vehicle, wherein, an ultrasonic probe thereof comprises four pairs of single-emission and single-receiving probes and six probes integrated with emission and receiving. In the four pairs of probes, the emission angle or receiving angle of each probe is 15-33 degrees; the torsion angle is 5-35 degrees; and each pair of probes is arranged according to the set position. In the six probes integrated with emission and receiving, two normal probes are respectively arranged at two sides of a rolling circle; the axialdistance with the rolling circle is 1-8 mm; the emission angles of two angle probes are parallel to the rolling circle surface and the axial distance with the rolling circle is 1-8 mm; and two probeswith the emission angle of 1-10 degrees are respectively arranged at two sides beside the rolling circle and the axial distance with the rolling circle is 1-4 mm. The device can carry out all-around detection on the defects of each type of wheel spoke; the detection process is free of manual work participation with high detection rate; and the detection method is simple and the detection result is reliable.
