Example Embodiment

[0019] Embodiment: A method for adjusting the parallelism between the transmitting surface of the ultrasonic transducer probe and the reflector, including the following steps:

[0020] (1) Install two laser transmitters on the side of the ultrasonic transducer probe, and adjust the position of the laser transmitter so that the emitted laser is perpendicular to the probe emitting surface, and two laser receiving points are correspondingly installed on the reflector. The sensor, first adjust when the ultrasonic transducer probe's emitting surface is initially parallel to the reflector, the two laser beams emitted by the laser transmitter are aligned with the two laser receiving point sensors in the reflector; the initial parallel adjustment method is as follows : Start the ultrasonic transducer probe, connect the ultrasonic transducer probe to the oscilloscope, repeatedly adjust the position of the reflector, and use the oscilloscope to observe the return time delay data of the ultr...

Abstract

The invention discloses a method and a device for regulating the emission surface of an ultrasonic transducer probe to be parallel to a reflecting plate. Two laser emitters are arranged at one side of the probe, and a laser receiving point sensor is correspondingly arranged on the reflecting plate. In actual application process, when the parallelism degree between the emission surface of the ultrasonic transducer probe and the ultrasonic reflecting plate deviates, and the upper, lower, left and right positions of the reflecting plate are repeatedly regulated till laser narrow beams emitted from the emission surface of the ultrasonic transducer probe realign to the laser receiving point sensor in the reflecting plate, thus the parallelism between the emission surface of the ultrasonic transducer probe and the reflecting plate can be determined. The invention has the advantages of convenient regulation, time and labor saving and high accuracy, reduces experiment preparation working intensity of instruction teachers and the experimental difficulty of students and improves the experimental efficiency and effect.

Description

technical field [0001] The invention relates to a device for measuring the spreading angle of an ultrasonic transducer, in particular to a method and a device for adjusting the emitting surface of the emitting probe of the ultrasonic transducer to be strictly parallel to the plane of the ultrasonic echo reflection plate before measuring the spreading angle. Background technique [0002] The utility model patent with the patent number "CN200720108554.9" discloses "a device for measuring the sound beam spread angle of an ultrasonic transducer", which uses the principle of geometric acoustics and adopts the method of measuring the ultrasonic echo signal of the rotatable signal reflector The method indirectly measures the sound field diffusion angle of the sound beam emitted by the ultrasonic transducer. This device is simple and practical, has strong operability, is convenient to assemble and disassemble, and is low in price. It replaces expensive imported equipment and is widel...
