Description

Technical Field

[0001] The utility model relates to the technical field of electric inductive proximity switches, in particular to a device for detecting the effectiveness of electric inductive proximity switches. Background Art

[0002] An inductive proximity switch is a sensor that works on the principle of inductive electromagnetic field and is used to detect the presence or position of a metal object. The principle is that when current passes through a coil, a magnetic field is generated. When a metal object approaches the inductive head, the metal object affects the magnetic field in the coil, causing eddy currents to be induced in the coil, thereby changing the inductance of the coil and the impedance of the coil. The proximity switch detects the change in impedance and converts it into an electrical signal, thereby realizing the detection of the metal object. Inductive proximity switches are widely used in the field of industrial automation, such as object detection on material conveying lines, position control of mechanical equipment, etc. Before an inductive proximity switch leaves the factory, it is necessary to test its effectiveness to ensure its effectiveness and performance, and to ensure that it can work accurately and reliably in actual applications. Therefore, a person skilled in the art provides a device for detecting the effectiveness of an inductive proximity switch to solve the problems raised in the above background technology.

[0013] Technical effects and advantages of the utility model:

[0014] The utility model clamps the electric inductive proximity switch by means of a clamping device, and then drives the residual gear to rotate by means of a motor, so that the residual gear successively meshes with the upper row of teeth and the lower row of teeth during rotation, thereby driving the arc frame and the metal object for detection to move back and forth, so that the metal object for detection repeatedly approaches and moves away from the electric inductive proximity switch, and it is possible to observe whether the switch can accurately detect the presence of the metal object and respond in time when the metal object is removed, and it is possible to observe the stability and reliability of the electric inductive proximity switch in a continuous working state, and to check whether it will have false triggering or other abnormal conditions.

[0015] The utility model can adjust the distance between the metal object for detection and the inductive proximity switch through the telescopic rod. By adjusting the detection distance of the inductive proximity switch, its detection ability of metal objects at different distances can be tested. In practical applications, it may be necessary to adjust the detection distance of the inductive proximity switch according to specific circumstances, so it is very important to verify the effectiveness at different distances.
