Electromagnet attraction detecting device

Abstract

The invention provides an electromagnet attraction detecting device capable of accurately obtaining an electromagnet attraction value by controlling an air gap value between an armature and an armature core so as to accurately display the electromagnet attraction, thereby eliminating laborious calculation and saving time. An electromagnet to be tested comprises a magnetic yoke, an armature and a coil. A convex armature core is arranged at the center of the magnetic yoke. The electromagnet attraction detecting device is characterized in that the electromagnet attraction detecting device comprises a base, a center positioning through hole is arranged in the center of the base; the central position of the magnetic yoke to be tested is fixedly installed in the center positioning through hole by a step pin; an upper plate is disposed right above the bas and is supported right above the base by a plurality of support rods; a vertical through hole is disposed right above the upper plate relative to the center positioning through hole; the middle screw portion of a upper pull rod passes through the vertical through hole and then is fixed to the upper plate by a upper nut and a lower nut; and the lower end of the upper pull rod is fixedly connected with the upper end of a tension sensor.

Description

technical field [0001] The invention relates to the technical field of electromagnet detection, in particular to an electromagnet suction detection device. Background technique [0002] The value of the suction force of the existing electromagnet needs to be obtained through complex calculations. Due to the complexity of the calculation process and the fact that the electromagnet itself will deviate from the design during production, the value obtained through complex calculations may not be accurate; In the actual production process, factors such as the ampere-turn value, the polarization area of ​​the iron core, the air gap value of the armature and the armature core will affect the suction force of the electromagnet, among which the ampere-turn value and the polarization area of ​​the armature are the characteristics of the part itself and are not easy to change. , and the air gap value of the armature and the armature core is relatively more likely to deviate, which make...
