Description

Technical Field

[0001] The utility model belongs to the technical field of sensor testing, and particularly relates to a testing device for mine sensors. Background Art

[0002] The increment of displacement per unit time is velocity. Velocity sensors include linear velocity sensors and angular velocity sensors. Among them, according to the contact method, angular velocity sensors are divided into two categories: contact type and non-contact type. The non-contact velocity sensor has no direct contact with the measured moving object, but measures the angular velocity of the rotating object through photoelectric, magnetoelectric and other methods. The non-contact velocity sensor has technical advantages such as long service life and no need to add compensation circuits. During the process of factory production of such velocity sensors, it is necessary to measure data such as the functional parameters, accuracy, and sensitivity of the sensors to ensure that the quality of the produced products meets the requirements of customers or corresponding standards;

[0003] After retrieval, the application (publication) number: CN220626411U discloses a testing device for mine velocity sensors, "including: a substrate, a support plate, a slider, a threaded rod, a mounting plate, a rotating gear mechanism, a scale, and a measuring plate. The support plate is fixed on the substrate, and the slider is placed on the substrate and located on the right side of the support plate. One end of the threaded rod sequentially passes through the support plate and the slider and is threadedly connected therebetween. The mounting plate is vertically fixed on the upper surface of the slider. The rotating gear mechanism is fixed on the substrate and located on the right side of the slider. The scale is horizontally arranged on the side of the mounting plate, and the scale is at the same height as the velocity sensor mounted on the mounting plate. The measuring plate is two pieces, one end of the measuring plate has a downwardly arranged bayonet, and the measuring plate is snap-fitted on the scale through the bayonet and is slidably connected therewith" and other technical features, having "able to more precisely adjust the distance between different velocity sensors and experimental gears, improving the accuracy of test results";

[0004] Although this method can perform tests when the sensor is at different distances from the object, the measuring plate needs to be disassembled and assembled each time during the test, increasing the work intensity. At the same time, the manual pushing method cannot control the speed consistency, affecting the test smoothness. At the same time, the device is arranged in a "one" shape, is narrow and long, and the overall proportion is uneven, which is not conducive to the stability of transportation, installation, and use;

[0005] At the same time, the device does not have a quick positioning and clamping mechanism for the sensor, and the deviation of the fixed position of the sensor during the test will affect the detection accuracy and effect;

[0006] To solve the above problems, a testing device for mine sensors is proposed in this application. Summary of the Utility Model

[0015] Further, the bottom of the pressing plate fits the outer contour of the speed sensor.

[0016] The present utility model has the following beneficial effects:

[0017] The present utility model ensures the horizontal movement of the speed sensor by setting a horizontal sliding seat and a sliding groove. At the same time, through the cooperation of the adjusting motor, the eccentric wheel and the driving groove, and driven by the adjusting motor, the speed sensor is driven to slide horizontally, ensuring the smooth and stable movement of the speed sensor, thereby improving the credibility of the data measured by the speed sensor.

[0018] The utility model facilitates the rapid positioning of the speed sensor by arranging a positioning groove and a positioning stop block on the test seat, and then the pressing plate presses the speed sensor tightly through the cooperation of the screw rod and the internal thread sleeve, thereby ensuring the consistency and stability of the position of the speed sensor during detection;

[0019] The scale pointer and the indicating sleeve provided by the utility model are directly in sliding cooperation with the test seat on the horizontal sliding seat, and the distance between the front end of the speed sensor and the test gear is indicated in real time, which improves the convenience of use while ensuring the accuracy of the distance. At the same time, the positions of the substrate, the driving motor, the test gear, the test seat, the adjusting component, and the clamping component are more evenly and compactly distributed, which is conducive to transportation, handling, and installation work.

[0020] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
