Abstract

The present invention discloses an electromagnet suction measuring device. The device comprises an armature, a matched tool, a guide rod, a displacement measurement unit, a spring dynamometer and a traction mechanism. The guide rod is connected with the armature through the matched tool and is capable of sliding along the axial direction of a to-be-measured electromagnet. The displacement measurement unit is used for measuring the displacement of the guide rod. The spring dynamometer is used for measuring the suction of the guide rod along the axial direction of the to-be-measured electromagnet. The traction mechanism is used for pulling the spring dynamometer to move along the axial direction of the to-be-measured electromagnet. According to the technical scheme of the invention, the displacement measurement unit directly measures the relative displacement between the guide rod and a guide groove. The spring dynamometer directly measures the value of the tensile force of the guide rod and the measurement accuracy is high. The value of the tensile force of the guide rod can be read at any displacement. Therefore, the suction measurement at any desired displacement can be realized, and the measurement process is simple.

Description

technical field [0001] The invention relates to the field of measurement, in particular to an electromagnet attraction measuring device. Background technique [0002] Electromagnet attraction is the core performance of an electromagnet, which needs to be accurately measured before use. [0003] In the Chinese utility model patent with the authorized notification number CN203376465U, an electromagnet suction measuring device is disclosed, which includes a fixed frame for fixing the electromagnet under test and an electromagnetic force applied to the iron block adsorbed on the electromagnet under test. The traction measurement mechanism of the separation force of the suction force; it also includes a cryogenic container for holding a low-temperature medium and a protective tank for immersing in the low-temperature medium of the low-temperature container, and the protective tank has an interior for placing the electromagnet under test. The cavity and the opening for the electr...
