Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic steel surface magnetism testing, and in particular relates to a magnetic steel surface magnetism testing fixture. Background Art

[0002] Magnets are also called hard magnets. They are not easy to lose magnetism and can maintain magnetism for a long time, such as natural magnets and artificial magnets. Surface magnetism is the magnetic induction intensity of a certain point on the surface of the magnet. The data is measured by a gaussmeter contacting the surface of the magnet. Companies that produce magnets generally need to conduct surface magnetism tests on finished magnets. When testing, the magnets need to be magnetized first, and then the magnets and gaussmeters need to be fixed separately using fixtures.

[0003] The current test equipment cannot keep the magnetic ring consistent with the fitting surface of the Gaussmeter when clamping it, and needs to be manually fixed. Manual fixation cannot maintain the vertical position of the Gaussmeter and the magnetic ring product. Therefore, during the test, the operation of adjusting the plane where the Gaussmeter is located to be tangent to the outer circle of the magnetic steel requires the operator to spend a long time, which can easily make the test data unstable, resulting in the analysis of the magnetic properties of such magnetic steel samples not corresponding to the actual values. Utility Model Content

Furthermore, it also includes a first cross bar, the first cross bar is embedded in the through groove, the end of the first cross bar is connected to a vertical upright pole, the upper end of the upright pole is connected to a horizontal second cross bar, the fixing sleeve is slidably connected to the second cross bar, and the end of the second cross bar is engaged with a third hand-tightened screw corresponding to the fixing sleeve.
