Ultrasonic detector testing device

Abstract

The invention discloses an ultrasonic detector testing device. The ultrasonic detector testing device comprises a tester, sliding blocks are slidably connected to the two sides of the top of the tester through threaded columns correspondingly, an ultrasonic detector transducer is slidably connected to the inner walls of the sliding blocks, and a positioning groove is formed in the surface of the ultrasonic detector transducer; and the left sides of the inner walls of the sliding blocks are fixedly connected with first bearings. According to the ultrasonic detector testing device, by arrangingthe tester, the sliding blocks, the ultrasonic detector transducer, the positioning groove, the first bearings, a positive and negative threaded column, threaded sleeves, an oblique plate, idler wheels, connecting plates, a lifting plate, sliding mechanisms, springs and a positioning column, the problems that the transducer of the ultrasonic detector cannot be well fixed through an existing testing device, the transducer is prone to falling off, and consequently, the testing result of the ultrasonic detector is affected are solved; and the ultrasonic detector testing device has the advantage that the fixing effect is good, the practicality of the testing device is improved, and using by a user is facilitated.

Description

technical field [0001] The invention relates to the technical field of ultrasonic detector testing, in particular to an ultrasonic detector testing device. Background technique [0002] Sound waves are the propagation form of the mechanical vibration state (or energy) of objects. The so-called vibration refers to the reciprocating motion of the particle of matter near its equilibrium position. Ultrasonic vibration frequency is greater than 20KHz, which exceeds the upper limit of human hearing (20000Hz). People call this inaudible sound wave ultrasonic. It usually propagates in the elastic medium in the form of longitudinal waves. It is a form of energy propagation. It is characterized by high ultrasonic frequency and short wavelength. It has good beam radiation and directivity when propagating in a straight line within a certain distance. [0003] The ultrasonic detector needs to be tested before it is put into use, but the existing testing device cannot fix the transducer...
