Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic non-destructive testing, in particular to a metal ultrasonic non-destructive testing device. Background Art

[0002] Non-destructive testing is an indispensable and effective tool for industrial development. The biggest feature of non-destructive testing is that it can be carried out without damaging the material and structure of the test piece. After the implementation of non-destructive testing, the inspection rate of the product can reach 100%. Ultrasonic non-destructive testing is to study the reflected, transmitted and scattered waves through the interaction between ultrasonic waves and test pieces, and perform macro-defect detection, geometric property measurement, detection and characterization of changes in organizational structure and mechanical properties of the test piece, and then evaluate the specific performance of the test piece. Therefore, a metal plate ultrasonic non-destructive testing device has appeared on the market.

[0003] At present, the existing metal ultrasonic non-destructive testing devices are mostly used for manual handheld testing when testing metal plates or pipes. During the testing, all areas on both sides of the metal need to be tested. During the testing, the detection probe needs to be close to the outer surface of the metal to be tested. When testing some wider plates, the detection efficiency is often poor. During the testing, the metal area needs to be tested back and forth, and the work intensity during the testing is relatively high. For this reason, we propose a metal ultrasonic non-destructive testing device. Utility Model Content

[0011] The utility model provides a metal ultrasonic nondestructive testing device, which has the following beneficial effects:

[0012] 1. The metal ultrasonic nondestructive testing device cooperates with a sleeve, a slide plate, a first spring, a metal ultrasonic testing probe, a servo motor, a reciprocating screw, a slider, a support plate, a slide rail, a track motor and a testing plate. During testing, it is only necessary to place the metal plate to be tested in the placement groove on the testing plate. The weight of the metal plate itself contacts the metal ultrasonic testing probe on the top of the testing table, which squeezes the first spring, thereby making one metal ultrasonic testing probe in close contact with the outer surface of the bottom of the plate. Subsequently, by turning on the electric telescopic rod, the other metal ultrasonic testing probe is pushed into precise contact with the upper surface of the plate to ensure accurate testing. Finally, by turning on the servo motor to drive the reciprocating screw to rotate, the slider can be driven to move back and forth horizontally through the thread. While moving, the width of a probe on the horizontal surface of the plate can be tested. The track motor can drive the testing plate to move longitudinally by the width of the metal ultrasonic testing probe so that the untested surface of the plate moves to the testing end of the metal ultrasonic testing probe, thereby performing comprehensive and automatic testing on the plate. The testing is convenient and fast, and the testing efficiency is higher.

[0013] 2. The metal ultrasonic nondestructive testing device is coordinated by a 7-type frame, a slide bar, a pressure plate, a back plate, a second spring and a guide rod. When testing the plate, the slide bar is pulled up and the metal plate is placed inside the placement groove. After releasing the slide bar, the elastic force of the second spring pushes the back plate to press the pressure plate down to fix the plate inside the placement groove. By opening an arc-shaped limit groove on the inner side of the detection plate and the pressure plate, the metal of the pipe can also be tested, and the compatibility is high.
