Ultrasonic detector testing device

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
