Machinery scanning machine comprises motor, the frame that motor is installed, frame is provided with the slideway that slides before and after the power supply machine, on the output shaft of motor chuck is installed, the position corresponding with the chuck of motor at the other end of frame is equipped with dop, and ultrasonic probe is installed in the rotating shaft of motor and between chuck and dop.
Machinery scanning machine dop is the support of a matrix, and the end axle of brake beam is placed in the support, respectively is provided with an adjustment sheet that adapts to the different diameters of axle on the anchor point of dop both sides.
The clamping leaf spring of static probe is installed on the ultrasonic probe.
During flaw detection, end axle and brake beam are placed on the dop, and chuck is sleeved on the end of holding axle, mechanical scanning machine is fixed on the end axle; Open the power switch of scanning machine then, ultrasonic probe is just advanced in the detected end axle surface formula of spinning under driven by motor, rotating through 100 square-wave signals of probe output in the journey each week, waveform recording is carried out in defective place; Such detection is not to judge that by a waveform flawless and defective are arranged, and any point on the part all is through the repeatedly detection of the ultrasonic signal of different azimuth, forms a synthesis result, and the crackle image of generation adopts rotatable 3 D stereo color graphics; Advanced technologies such as the ultrasonic analysis instrument of defectoscope and high-speed data acquisition card, ultrasonic signal can be converted to the digital signal that computing machine can be handled, carry out the analyzing and processing of data by the defectoscope special software, carry out determining defects, improve the accuracy of carrying out flaw detection greatly, can effectively avoid omission, flase drop.
The technical progress that the utility model is obtained is:
Realization is to surface crack, weld ripples defective and be bumped into automatic judgement, demonstration and the printout of the comprehensive flaw detection of position crackle, inherent vice, reduce leak visit, the wrong spy, guarantee vehicle transport safety.
Because the utility model volume is little, in light weight, easy to install, therefore can be applied on the repair assembly line, carry out continuity production.
Through end axle of brake beam being carried out the contrast of wet method magnetic powder inspection and two kinds of operations of UT (Ultrasonic Testing),, in the UT (Ultrasonic Testing) inspection, can all detect end axle crackle that find in the wet method magnetic particle testing or undiscovered; Particularly the opposite end axle is bumped into ND positions such as brake head position and inherent vice, and the utility model has been given full play to advantages such as its flaw detection accuracy rate height, misjudgement, misdetection rate are low.The utlity model has reliable usability, can effectively prevent the brake beam case accident that causes because of the end axle of brake beam rhegma, guarantee safety of railway traffic, avoid the economic loss of bringing because of driving accident.
