Description

technical field [0001] The invention relates to the technical field of ultrasonic flaw detection auxiliary devices, more specifically, it relates to an ultrasonic probe operating device with a pressure sensor. Background technique [0002] Ultrasonic flaw detection is a method for inspecting parts defects by using ultrasonic energy to penetrate deep into the metal material and pass from one section to another section, reflecting at the edge of the interface to inspect parts defects. Inside the metal, when a defect and the bottom surface of the part are encountered, reflected waves will be generated respectively, and pulse waveforms will be formed on the fluorescent screen. Based on these pulse waveforms, the position and size of the defect can be judged. [0003] At present, the common ultrasonic probe is an oblique probe, which includes a probe body and an inclined wedge located at the lower end of the probe body. A piezoelectric wafer and a damping block are arranged in th...

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when testing, it is necessary to manually apply a certain pressure to the probe to make the rest of the measured workpieces fit closely. When the applied pressure is too large, the wear of the probe will be accelerated; Hours will affect the accuracy of the detection. It takes a certain amount of work experience for the master to grasp this strength, which makes it difficult for novices to accurately grasp the magnitude of the applied pressure.
