The invention discloses an ultrasonic measuring device for automatically detecting the wall thickness of a thin-walled tube, and in the device, a lifting cylinder is mounted on a cylinder fixing plate, and a connecting frame is mounted on the lifting cylinder; a cylinder bracket is fixed at the upper part of the connecting frame, and the lower part of the connecting frame is connected with a measurement fixing frame arranged in the water tank; the pressing air cylinder is installed on the air cylinder support, and the pressing block is installed on an output shaft of the pressing air cylinder. The buffer block is fixedly connected with the pressing block; the floating measurement module is located in the water tank and connected with the measurement fixing frame. The lifting air cylinder drives the floating measurement module to move up and down through the connecting frame and the measurement fixing frame. A workpiece to be measured is arranged between the floating measurement module and the buffer block, a cylindrical positioning block on the floating measurement module is in contact with the workpiece after the lifting cylinder is lifted, the pressing cylinder extends out, the workpiece is pressed through the pressing block and the buffer block, and therefore stable measurement of the wall thickness is achieved through an ultrasonic probe on the floating measurement module.
Description
technical field [0001] The invention relates to the field of ultrasonic measurement, in particular to an ultrasonic measurement device for automatic detection of the wall thickness of thin-walled pipes. Background technique [0002] Thin-walled tubes are widely used in aerospace, nuclear industry, automobile and other fields, and the quality requirements for the tubes have become very strict, and there are high requirements for uniform wall thickness. In order to ensure the uniform wall thickness of thin-walled aluminum tubes Firstly, it is necessary to select a suitable detection method to realize the automatic detection of the wall thickness of thin-walled aluminum tubes. [0003] At present, there are many methods for testing the wall thickness of seamless pipes. The more mature thickness measurement methods include eddy current method, laser method, magnetic flux leakage method, ray thickness measurement method and ultrasonic method. Compared with other non-destructive ...
