Description

Technical Field

[0001] This utility model relates to the field of inductive proximity switch technology, specifically a frequency testing device. Background Technology

[0002] Inductive proximity switches are a low-cost method for non-contact detection of metal objects. When a metal object moves toward or away from the proximity switch, the signal changes automatically, thus achieving the purpose of detection.

[0003] In the prior art, when performing frequency detection on an inductive proximity switch, the detection metal plate in the inductive proximity switch is fixed on a rotatable push plate, and the sensor is fixed at a position relative to the detection metal plate. Generally, only the left-right relative distance between the detection metal plate and the sensor can be adjusted. When adjusting the front-back distance between the detection metal plate and the sensor, it can generally only be adjusted by adjusting the placement position of the sensor, which is a rather cumbersome operation.

A touch controller 18 is installed on the top of the test box 1 near the oscilloscope plotting component 17. The touch controller 18 is used to control the various components in the device and can display the data processed by the oscilloscope plotting component 17. A switch 19 for controlling the motor 2 is installed on the middle platform of the test box 1. Several switches 19 can control the motor 2, the touch controller 18 and the oscilloscope plotting component 17 to start, stop and turn off. A receiving slot 20 for storing the test metal plate is opened on one side of the tray 3. The receiving slot 20 can provide a relatively stable installation position for the test metal plate.

[0022] like Figures 1 to 4 As shown, a first slide rail 9 is fixedly installed in the middle of the vertical moving seat 6, and a second locking block 8 is slidably installed on the outside of the first slide rail 9. An elastic element 10 is installed between one end of the second locking block 8 and the vertical moving seat 6.

[0023] Push the second locking block 8 to slide along the outer side of the first slide rail 9. At this time, the elastic element 10 is in a compressed state, and the sensor is installed between the first locking block 7 and the second locking block 8. The sensor is stably installed between the first locking block 7 and the second locking block 8 by the pushing of the elastic element 10 on the second locking block 8, which facilitates the assembly of the sensor.

A micrometer head 13 is fixedly installed at the top of the horizontal moving seat 5, and the moving end of the micrometer head 13 is fixedly connected to the middle of the vertical moving seat 6.

[0025] By rotating the handle 16, the screw 15 will be rotated. The horizontal moving seat 5 will move between the two limit rods 14 through the threaded connection between the horizontal moving seat 5 and the screw 15, thereby adjusting the relative left and right position between the sensor and the detection metal plate.

[0026] like Figures 1 to 4 As shown, the fixed seat 4 has symmetrically fixedly installed limit rods 14 inside, the horizontal moving seat 5 is slidably installed between the two limit rods 14, the middle part of the fixed seat 4 is rotatably installed with a screw 15 through a bearing, one end of the screw 15 is fixedly installed with a handle 16, and the screw 15 is threadedly connected to the middle part of the horizontal moving seat 5.

[0027] By rotating the knob at the end of the micrometer head 13, the vertical moving base 6 connected to the moving end of the micrometer head 13 will move along the trajectory of the fixed slider 11, thereby adjusting the distance between the sensor and the detection metal plate.

[0029] When using the device, the detection metal plate is installed inside the receiving groove 20 of the tray 3, and the second locking block 8 is pushed to slide along the outside of the first slide rail 9. At this time, the elastic element 10 is in a compressed state, and the sensor is installed between the first locking block 7 and the second locking block 8.

Then, by turning the handle 16, the screw 15 will be driven to rotate. The horizontal moving seat 5 will be driven to move between the two limit rods 14 through the threaded connection between the horizontal moving seat 5 and the screw 15. Then, by turning the knob at the end of the micrometer head 13, the vertical moving seat 6 connected to the moving end of the micrometer head 13 will be driven to move along the trajectory of the fixed slider 11, thereby adjusting the distance between the sensor and the detection metal plate.
