Description
Technical Field
The utility model relates to the technical field of magnetic proximity switch detection, in particular to a portable magnetic proximity switch detection device.
Background
The magnetic proximity switch uses a soft magnetic reed as a contact switch, and can sense the position of a measured object by utilizing the magnetization characteristic of a magnetic field of a soft magnet and matching with an external magnet, and is generally used for position detection. The most important performance parameter of the magnetic proximity switch is the operating distance, which is the farthest distance that the test magnet can just make the magnetic proximity switch conductive, and determines whether the external magnet can make the magnetic proximity switch conductive within a specified range.
The detection method of the magnetic proximity switch is generally divided into two methods, one method is that the magnetic proximity switch is connected in series to a detection circuit on a test platform, a standard detection magnet slowly approaches from a far end through a controller, the distance of the switch triggered to be conducted is recorded, and whether the distance is within a specified action distance range is checked. The method needs to build a complex platform and a control circuit in the early stage, the platform is large and heavy, the magnetic proximity switch is inconvenient to take, place and move, the magnetic proximity switch needs to be completely fixed on the platform during testing, the magnetic proximity switch installed on an instrument needs to be disassembled to be detected, and the use is limited. And secondly, limiting the action distance between the test magnet and the magnetic proximity switch to the minimum required action distance through a tool, and checking whether the magnetic proximity switch can be triggered to be conducted or not. According to the method, the distance between the test magnet and the magnetic proximity switch is fixed through the tool, so that the size of the detection device is reduced, but the distance is fixed on the minimum value required by the action distance, so that only the defective products with the reduced action distance can be effectively detected, and the defective products with larger action distance cannot be detected.

Detailed Description
The following describes embodiments of the present invention in detail with reference to the drawings, which are implemented on the premise of the technical solution of the present invention, and give detailed implementation manners and specific working procedures, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1 and 2, the portable magnetic proximity switch detection device of the present invention includes a rectangular housing 1, a detection circuit is installed on the top of the housing, the detection circuit includes a button cell 201 (power supply), an LED lamp 202 (indicator) and a plug 203, which are connected in series through a wire, and the plug 203 is used for connecting a switch M to be detected. The first chamber 3 that holds has been seted up at casing 1 middle part, and the second that is used for placing the switch M that awaits measuring is seted up to the bottom holds the chamber 4. The first receiving chamber 3 is provided therein with a moving member 6 for connecting a test magnet 5, both of which are moved generally in the longitudinal direction of the housing 1, i.e., in the arrangement direction of the first receiving chamber 3 and the second receiving chamber 4. In this embodiment, the test magnet 5 is mounted on the side surface of the moving member 6 by a bolt, and the bottom surfaces thereof are flush with each other. In order to provide sufficient space for the test magnet 5 and the moving member 6 to move, the distance between the top surface (i.e., the second end surface) and the bottom surface (i.e., the first end surface) of the first accommodating chamber 3 is generally greater than the longitudinal length of the test magnet 5 and the moving member 6; meanwhile, the first end face and the second end face limit the moving distance of the test magnet 5, so that the switch M to be tested can be conveniently detected within a specified action distance range. In general, the position where the test magnet 5 is closest to the switch M to be tested is referred to as a first position, and the position where the test magnet 5 is farthest from the switch M to be tested is referred to as a second position. In order to push and pull the moving member 6, a guide rod 7 capable of penetrating out of the shell 1 is arranged at the top of the moving member 6, and correspondingly, a guide hole matched with the shape of the guide rod 7 is formed in the top surface of the shell 1. Further, in order to improve the convenience of operation, a return spring 8 is installed between the bottom surface of the moving member 6 and the bottom surface of the first receiving chamber 3, so that the test magnet 5 and the moving member 6 can be automatically returned after being pushed. At this time, the first position of the test magnet 5 is the position where the return spring 8 is maximally compressed, and the second position is the position where the test magnet 5 is located when the top surface of the moving member 6 is in contact with the top surface of the first accommodating chamber 3. However, in actual operation, the position of the test magnet 5 when the top surface of the moving member 6 contacts the top surface of the first accommodating chamber 3 should be slightly larger than the maximum distance of the specified action of the test magnet 5, so that the LED lamp 202 does not emit light when the test magnet 5 is in the initial position. In order to conveniently take and place the switch M to be tested, the second accommodating cavity 4 is a semi-closed groove matched with the switch M to be tested.
When the LED lamp is used, firstly, the switch M to be tested is installed in the second accommodating cavity 4, then the switch M to be tested and the plug-in connector 203 are connected through a wire, then the guide rod 7 is slowly pressed, the moving piece 6 drives the test magnet 5 to move downwards, and if the switch M to be tested is qualified, the test magnet 5 triggers the switch M to be tested at a certain position in the stroke, so that the LED lamp 202 emits light; on the contrary, if the LED lamp 202 already emits light when the test magnet 5 is in the initial state or the LED lamp 202 still does not emit light when the test magnet 5 reaches the second position, it is determined that the switch M to be tested is not qualified.
It should be noted that in the description of the present invention, terms such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
