Problems solved by technology

This method uses tooling to fix the distance between the test magnet and the magnetic proximity switch to reduce the size of the detection device. However, since the distance is fixed at the minimum value required for the operating distance, it can only effectively detect defective products with smaller operating distances. Large defective products cannot be detected

Abstract

The invention discloses a portable magnetic proximity switch detection device, which comprises: a shell provided with a first accommodating cavity and a second accommodating cavity for placing a to-be-detected switch; a test magnet arranged in the first accommodating cavity and provided with a first position closest to the to-be-detected switch and a second position farthest from the to-be-detected switch, wherein the test magnet moves between the first position and the second position; and a detection circuit provided with a power supply, an indicating piece and a connecting plug for connecting the to-be-detected switch, wherein the power supply, the indicating piece and the connecting plugare connected in series. According to the invention, the portable magnetic proximity switch detection device is ingenious in structure, small in size and easy to operate; a to-be-detected switch can be conveniently installed in a semi-closed second accommodating cavity, a pressing type moving piece capable of automatically returning is used in cooperation with a first accommodating cavity with a limiting function to replace the lead screw transmission mode of a traditional detection platform and the fixing mode of a detection tool, and the moving path and the moving distance of a detection magnet are limited, so that the detection magnet moves more conveniently and quickly.

Description

technical field [0001] The invention relates to the technical field of magnetic proximity switch detection, in particular to a portable magnetic proximity switch detection device. Background technique [0002] The magnetic proximity switch uses a soft magnetic reed as a contact switch. It uses the magnetization characteristics of a soft magnetic body by a magnetic field and cooperates with an external magnet to sense the position of the measured object. It is usually used for position detection. Among the performance parameters of the magnetic proximity switch, the most important is the operating distance, which refers to the farthest distance that the test magnet can just make the magnetic proximity switch conduct, and determines whether the external magnet can make the magnetic proximity switch conduct within the specified range. [0003] There are generally two detection methods for magnetic proximity switches. One is to connect the magnetic proximity switch in series to ...
