Embodiment Construction
[0019] The specific embodiment of the present invention will be further described below in conjunction with the accompanying drawings. The basic innovation of the scanning device of the present invention is: a scanning support for a trolley car that moves in a plane is designed, and the scanning support includes a panel 3 provided with four universal wheels and an embedded The rectangular bracket 13 of the scanning probe 1 and the pin shaft 9 for the scanning probe are embedded in the chute 14 on both sides of the end of the bottom surface of the rectangular bracket. To enable the scanning device to achieve stable coupling with the workpiece, a magnet 10 is arranged at the bottom of the rectangular bracket. In order to make the probe move smoothly during ultrasonic flaw detection, a damping spring 7 is arranged in the holding bracket above the scanning probe. The vibration damping spring is four circles arranged in the middle of the upper spring pressing block 6 and the lower ...

The present invention relates to an ultrasonic wave detection scanning apparatus capable of achieving stable coupling. The ultrasonic wave detection scanning apparatus comprises a scanning support, a scanning probe and moving universal wheels, wherein the scanning support comprises a panel provided with the four universal wheels and a rectangular bracket for installing the scanning probe in an embedded manner, the scanning probe is installed on the sliding grooves on both sides on the rectangular bracket bottom surface end head in the embedded manner by using a hinged shaft, the bottom of the rectangular bracket is provided with a magnet, and a vibration reduction spring is arranged above the scanning probe. The ultrasonic wave detection scanning apparatus has the following beneficial effects that: the suction force of the magnet on the work-piece and the vibration reduction spring arranged on the rectangular bracket are adopted to achieve stale running of the probe during flaw detection with the ultrasonic wave and reduce the detection result deviation caused by human factors, the operator pushes the scanning apparatus to move on the surface of the work-piece with hands during use so as to provide strong practicality, the scanning speed is increased, and the production efficiency is significantly improved.
Description
technical field [0001] The invention relates to a scanning device for ultrasonic detection capable of realizing stable coupling, and belongs to the technical field of ultrasonic flaw detection supporting equipment. Background technique [0002] In the current ultrasonic flaw detection process, the coupling agent is applied to the surface of the workpiece, and the operator holds the ultrasonic probe to move on the surface for detection. Since the coupling between the probe and the flaw detection surface directly affects the detection results during ultrasonic flaw detection, it is difficult to ensure the stability of the coupling during flaw detection manually. Contents of the invention [0003] In order to solve the coupling stability of the existing ultrasonic detection surface, ensure the stable quality of flaw detection, and improve the detection efficiency, the present invention provides an ultrasonic detection scanning device capable of providing continuous and stable...
