Description

Technical Field

[0001] The utility model relates to the technical field of sensor testing, and more specifically to a measuring device for an eddy current sensor. Background Art

[0002] Sensors made based on the eddy current effect are called eddy current sensors, which are widely used in the electric power, petroleum, chemical, metallurgy and other industries. In the production process of eddy current sensors, measuring devices are needed to test their sensitivity to ensure product quality and reduce the probability of failure in actual use.

[0003] Based on the above, it is found that when the existing measuring device is in use, it is difficult to quickly and accurately adjust the distance between the eddy current sensor and the test sample block, making it difficult for the eddy current sensor to be moved to the specified position quickly and accurately, resulting in the test data of the eddy current sensor being inaccurate. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a measuring device for an eddy current sensor. This solution can quickly and accurately adjust the sensor and the test sample block to ensure the accuracy of the test data of the eddy current sensor, and can guide the movement of the moving component while reducing the moving friction to ensure the movement stability of the moving component.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A measuring device for an eddy current sensor comprises a base, one end of the base is fixedly connected to a driving motor, and the top surface of the base is fixedly connected to a control display on one side, a pair of support frames are slidably connected to the center of the top surface of the base, stabilizing mechanisms are provided on both sides of the support frames, the output end of the driving motor is fixedly connected to a screw rod, a pair of ball sliders are sleeved on the outer side of the screw rod, the top surface of the support frame is fixedly connected to a mounting plate, two mounting plates are respectively penetrated by sensing probes and test sample plates, and one end of the sensing probe is electrically connected to the control display.

[0007] Furthermore, the stabilizing mechanism comprises a guide rail, a support rod is sleeved on the outer side of the guide rail, grooves are provided on both sides and the top surface of the guide rail, and one end of the support rod is movably connected to a plurality of movable balls on the inner side.

[0008] Furthermore, the screw rod and the ball slider are both located inside the base, and the screw rod is movably connected to the base, and the ball slider is slidably connected to the base.

[0009] Furthermore, the outer surface of the screw rod is provided with two sections of rotating threads with the same length and opposite directions, and the two sections of rotating threads are respectively matched with two ball sliders, and the top surface of the ball slider is fixedly connected to the bottom surface of the support frame.

[0010] Furthermore, nuts are threadedly connected on both sides of the connection between the sensing probe and the test sample plate and the corresponding mounting plate.

[0011] Furthermore, the support rod is arranged in an L shape, and an inner end of the support rod is fixedly connected to the support frame.

[0012] Furthermore, the guide rail is fixedly connected to the top surface of the base, and one side of the movable ball is fitted in the groove.

[0013] Compared with the prior art, the utility model has at least the following beneficial technical effects:

[0014] (1) This solution fixes the sensor probe and the test sample plate by setting up two mounting plates. Then, the rotation of the screw rod cooperates with the two rotating threads to make the two support frames drive the two mounting plates to move synchronously in opposite directions, thereby adjusting the distance between the sensor probe and the test sample block. Compared with the existing technology, the sensor and the test sample block can be adjusted quickly and accurately to ensure the accuracy of the test data of the eddy current sensor.

[0015] (2) By setting up a stabilizing mechanism, the movement of the support frame drives the support rod to slide on the outside of the guide rail. The guide rail is fixedly connected to the top surface of the base, and one side of the movable ball is in contact with the groove. When the support rod moves, the movable ball rubs against the groove, and the movable ball rotates, thereby reducing the moving friction. Compared with the prior art, the moving component can be guided and the moving friction can be reduced, thereby ensuring the moving stability of the moving component.
