Detection distance control mechanism for magnetic flux density detection

Abstract

The invention discloses a detection distance control mechanism for magnetic flux density detection. The detection distance control mechanism comprises: a motion assembly and a detection assembly. The motion assembly comprises a base, a ball sliding table cylinder, a horizontal manual precision sliding table and a vertical manual precision sliding table. The detection assembly is fixedly arranged on the outer side of the vertical manual precision sliding table and comprises: a bottom plate, a roller mounting frame, a detection roller and a Hall element. The roller mounting frame is movably arranged on the outer side of the bottom plate and may move relative to the bottom plate. A sensor fixing block is disposed on the outer side of the roller mounting frame. The Hall element is arranged on the outer side of the sensor fixing block. A detection roller is disposed on both sides of the Hall element. The detection roller and the roller mounting frame are connected through a pin roll. The detection distance control mechanism can freely adjust required detection distance, can precisely control the detection distance in a motion situation, and is suitable for a non-flat surface of a product to be measured.

Description

technical field [0001] The invention relates to the field of magnetic flux density detection, in particular to a detection distance control mechanism for magnetic flux density detection. Background technique [0002] In the existing manual and automatic magnetic flux density detectors, the structure of the detection terminal is mostly fixed, that is, a fixed platform is used to carry the Hall element. During the detection process, the relative position of the whole group structure and the object under test does not change. , It is mostly used to detect the magnetic flux density of planar magnets, fixed-point magnets or magnet products that do not require high precision. [0003] The detection component structure of the existing magnetic flux density detection equipment cannot accurately adjust the required detection distance, or can only correspond to a single detection distance; in the case of mobile detection, it is impossible to accurately detect the magnetic flux density...
