Description

Protective magnetic core checking fixture Technical Field The utility model relates to the field of magnetic core detectors, in particular to a protective magnetic core detector. Background The magnetic core gauge is special testing equipment for detecting the dimensional accuracy of magnetic materials, and can be used for rapidly identifying product defects in an automatic or manual mode to ensure that the magnetic core meets design standards, and is mainly applied to the electronic element manufacturing, power equipment and communication industries to ensure the quality stability of products. The existing magnetic core checking fixture lacks protection function, and therefore the problem that the rejection rate is improved due to the fact that the magnetic core is rubbed or bumped with a tabletop for many times when the position of the magnetic core is moved in detection is likely to occur due to the fact that the protection function is not achieved. Therefore, aiming at the problem that the existing magnetic core checking fixture lacks protection function, the magnetic core is damaged due to contact friction with a tabletop, so that the rejection rate is improved, a novel protection type magnetic core checking fixture is needed to be designed. Disclosure of utility model In order to overcome the problem that the existing magnetic core checking fixture lacks the protection function, the magnetic core is in contact friction with a tabletop to generate damage in appearance, so that the rejection rate is improved. The technical scheme includes that the protective magnetic core testing fixture comprises an outer diameter testing fixture, a placing groove, a mounting platform, a falling groove, supporting legs and an inner diameter testing fixture, wherein the placing groove is formed in the middle position of the left surface and the right surface of the outer diameter testing fixture, the mounting platform is mounted on the lower side of the inner portion of the outer diameter testing fixture, the falling groove is formed in the middle position of the upper surface of the mounting platform in a penetrating mode, the supporting legs are mounted on the front side and the rear side of the lower surface of the outer diameter testing fixture, a sliding assembly is arranged between the two supporting legs, and the inner diameter testing fixture is arranged on the upper surface of the sliding assembly.
