Background

The nondestructive testing is a method for inspecting and testing the structure, properties and states of the interior and the surface of a test piece by taking a physical or chemical method as a means and by means of advanced technologies and equipment on the premise of not damaging the test piece. The method is a detection means which is implemented on the material or the workpiece and does not damage or influence the future service performance or application of the material or the workpiece.

The common nondestructive testing methods include Ray Testing (RT), ultrasonic Testing (UT), magnetic powder testing (MT) and Penetration Testing (PT), which are called four conventional testing methods. The four methods are the most common nondestructive testing methods for manufacturing quality testing and in-use testing of pressure-bearing special equipment. RT and UT are mainly used for detecting the internal defects of the test piece, and MT and PT are mainly used for detecting the surface defects of the test piece. Other nondestructive testing methods for pressure-bearing special equipment include eddy current testing (ET for short), acoustic emission testing (AE for short) and the like.

The internal structure of a coarse-grain metal material with a larger wall thickness or a nonmetal composite material with a smaller wall thickness is detected, after the processing is finished, a workpiece is detected by using a penetration method UT, a probe is placed in a probe fixing device according to the thickness of the workpiece to be detected during the detection, and then the probe is placed at the farthest position by adjusting a telescopic rod. Then the telescopic rod is moved to achieve the purpose of detecting the product. The detection method is used for finding the defects of slag inclusion, delamination, white spots and the like in the material.

This auxiliary device can realize quick fixed effect of accuracy again promptly.

The applicant finds that at least the following technical problems exist in the prior art: in the detection process, one person uses two hands to operate simultaneously, so that the two probes are difficult to be simultaneously ensured to be positioned at the same position and the workpiece is slightly larger, and a place which cannot be detected exists; two people use one hand to operate simultaneously, and it is difficult to ensure that the two probes are in the same position simultaneously. Thereby causing low detection pin rate and high labor cost.
