Description

Technical Field

[0001] The utility model relates to a Barkhausen probe fixing device. Background Art

[0002] During the grinding process, ferromagnetic workpieces are easily affected by the sharp increase in grinding surface temperature, which can easily cause grinding burn defects on the grinding surface, seriously affecting the performance and life of the workpiece. Currently, the commonly used methods include acid leaching, metallographic structure analysis, and Barkhausen noise detection. Among them, the Barkhausen detection method has the advantages of non-destructive detection and detection of substrate burns through the coating, and is increasingly widely used in the industry.

[0003] In actual application, the Barkhausen test is usually performed by holding the front end of the probe, touching the working surface of the probe to the surface of the workpiece to be tested, and moving at a constant speed on the working test surface along the grinding tangent direction with the contact point as the starting point. During this process, the working surface of the probe must always be placed vertically on the surface of the workpiece to be tested. The probe needs to be held for a long time, and the human operation error is large, which can easily affect the accuracy of the test results. Utility Model Content

[0024] A cylindrical pin 62 for connecting with the second locking assembly 5 is disposed at the bottom of the probe fixing frame 6 .

[0025] In this embodiment, the first locking assembly 3 and the second locking assembly 5 have the same structural principle, and the second locking assembly 5 is described in detail below with reference to the accompanying drawings as an example:
