AI Technical Summary

Technical Problem

In the material corrosion performance test, the existing ultrasonic detection methods have incomplete fixed-point detection, inability to detect different materials at the same time, lack of control data, inconvenient manual operation, and difficult to control the amount of coupling agent added, which affects the test accuracy.

Method used

An intelligent online testing device for material corrosion performance was designed, using a material fixing mechanism composed of upper pressure plate, suspender rod, upper limit slot, collection groove, lower pressure plate, lower limit slot, and external thread sleeve. Combined with the rotation mechanism of the motor, first shaft, main gear, driven gear, and second shaft, the rotational testing of the ultrasonic probe is realized, and the coupling agent is automatically added through the nozzle to ensure the test accuracy.

Benefits of technology

It realizes online testing of multiple groups of materials simultaneously, reduces random errors, acquires the overall characteristics of the materials, improves the accuracy and efficiency of the test, and ensures the transmission efficiency of ultrasonic waves.

Abstract

The present invention discloses an intelligent online testing device for material corrosion performance and a method for using the same, which belongs to the technical field of material corrosion performance testing, and includes a base, a reaction pool located on the top of the base, a cover plate covering the top of the reaction pool, and a cylinder for controlling the lifting of the cover plate. The present invention uses a material fixing mechanism composed of an upper pressure plate, a suspension rod, an upper limit groove, a collecting groove, a lower pressure plate, a lower limit groove, and an external threaded sleeve, which can simultaneously load and test multiple groups of materials during the test, reduce random errors, and help obtain the overall characteristics of the material. In addition, an ultrasonic probe is provided at the top of the material fixing mechanism and above the material fixing position. At the same time, a rotating mechanism composed of a motor, a first shaft rod, a main gear, a driven gear, and a second shaft rod can be used to continuously control the ultrasonic probe to rotate around the axis of the material during the test, and continuously test the single-sided average corrosion of the material, so that the test structure is more accurate.
