Description

Technical Field

[0001] The utility model relates to the technical field of eddy current ranging calibration mechanical structures, and particularly relates to an eddy current ranging sensor calibration device. Background Art

[0002] An eddy current ranging sensor is a distance measurement device based on the principle of electromagnetic induction and is widely used in industrial inspection, automation control and other fields; in the stone processing and building decoration industries, precise control of the distance between the stone and the pendant is particularly crucial, which directly affects the aesthetics and safety of the final product; in order to ensure that the eddy current ranging sensor can accurately measure the distance, it needs to be calibrated before being put into use to correct possible errors.

[0003] Deficiencies of the Prior Art

[0004] 1. Manual adjustment is inaccurate: Traditional calibration methods usually rely on manual adjustment by operators, and it is difficult to meet high-precision requirements with this method. Especially when adjusting small distances, deviations are likely to occur.

[0005] 2. Lack of an integrated solution: Some existing calibration devices have relatively single functions and often only focus on solving certain specific problems (such as only being able to adjust the probe height or horizontal position), and do not provide a highly integrated and easy-to-operate overall solution.

[0006] 3. Poor adaptability: There are large differences in the sizes of different types of stones and pendants. The clamping devices in the prior art lack flexibility and cannot well meet the needs of various specifications of materials.

[0007] 4. Insufficient reliability of measurement results: Due to the lack of an effective feedback mechanism or auxiliary positioning tools, the stability and repeatability of measurement data are poor during actual use.

[0008] Therefore, there are deficiencies in the prior art and further improvement is needed. Content of the Utility Model

[0009] In view of the problems existing in the prior art, the utility model provides an eddy current ranging sensor calibration device.

[0010] To achieve the above object, the specific scheme of the utility model is as follows:

[0011] The utility model provides an eddy current ranging sensor calibration device, including:

[0012] a probe, a two-dimensional adjustment mechanism, a first clamping mechanism, a second clamping mechanism, and a distance adjustment mechanism;

[0013] The two-dimensional adjustment mechanism, the first clamping mechanism, the second clamping mechanism, and the distance adjustment mechanism are sequentially arranged on a base from left to right;

[0014] The probe is arranged on the two-dimensional adjustment mechanism. The first clamping mechanism is used to clamp the stone, the second clamping mechanism is used to clamp the hanging piece, and the distance adjustment mechanism is used to adjust the position of the second clamping mechanism, so as to change the distance between the stone and the hanging piece;

[0015] The distance adjustment mechanism includes a first motor, a first lead screw, and a first nut;

[0016] The first motor is installed on the base. One end of the first lead screw is connected to the rotating shaft of the first motor. The first nut is installed on the second clamping mechanism and is simultaneously threadedly connected to the first lead screw;

[0017] The first motor drives the first lead screw to rotate forward and backward, thereby driving the first nut to move reciprocally, so as to adjust the distance between the second clamping mechanism and the first clamping mechanism.

[0018] Furthermore, the two-dimensional adjustment mechanism includes a first column, a first slider, and a second slider;

[0019] A first slide rail is arranged on the side wall of the first column in the up and down direction. The first slider is installed on the first slide rail so as to be movable up and down;

[0020] A second slide rail is arranged on the first slider in the horizontal direction. The second slider is installed on the second slide rail;

[0021] The probe is installed on the second slider;

[0022] The probe abuts against the left side of the stone. The height of the probe is adjusted by adjusting the first slider up and down, and the horizontal position of the probe is adjusted by adjusting the second slider horizontally, so as to adjust the relative position between the probe and the stone.

[0023] Furthermore, a first handle is arranged on the side surface of the first slider, and a second handle is arranged on the side surface of the second slider.

[0024] Furthermore, the first clamping mechanism includes a first clamping plate and a second clamping plate;

[0025] The first clamping plate and the second clamping plate clamp the stone therebetween. The first clamping plate and the second clamping plate are detachably installed on the base, and are used to adjust the distance between the first clamping plate and the second clamping plate, so as to facilitate clamping of stones with different thicknesses, and at the same time, the distance between the first clamping mechanism and the two-dimensional adjustment mechanism is also adjusted.

[0026] Furthermore, the second clamping mechanism includes a third slide rail, a third slider, a first side plate, a first mounting plate, a second mounting plate, a third clamping plate, and a fourth clamping plate;

[0027] On both sides of the base along the length direction, a third slide rail is respectively arranged, a third slider is arranged on each third slide rail, and a first side plate is mounted on each third slider;

[0028] The first nut is also mounted on the first mounting plate;

[0029] A second mounting plate is mounted at the upper ends of the two first side plates, and the first mounting plate is connected to the second mounting plate;

[0030] The third clamping plate and the fourth clamping plate are mounted in parallel on the top of the second mounting plate for clamping the hanging parts;

[0031] The first motor drives the first lead screw to rotate, thereby driving the first nut to move, further driving the first mounting plate and the second mounting plate to move, and further driving the third clamping plate and the fourth clamping plate to move.

[0032] Further, a third handle is passed through the third clamping plate and the fourth clamping plate;

[0033] The outer wall of the third handle is provided with threads. By rotating the handle, the fourth clamping plate is driven to move, so as to adjust the distance between the third clamping plate and the fourth clamping plate, and realize the clamping of the hanging parts.

[0034] Further, a scale or a laser distance measuring mechanism is also arranged on the side wall of the base to ensure the accuracy of distance measurement.

[0035] Adopting the technical scheme of the present utility model, the following beneficial effects are obtained:

[0036] 1. High-precision distance adjustment:

[0037] By using the combination of the first lead screw driven by the first motor and the first nut, the distance between the stone material and the hanging parts can be accurately controlled. This mechanical transmission method provides stable and accurate distance adjustment ability, and is suitable for application occasions requiring high-precision measurement.

[0038] 2. Flexible two-dimensional positioning:

[0039] The probe is mounted on the two-dimensional adjustment mechanism, and the position of the probe relative to the stone material can be adjusted by moving the first slider up and down and moving the second slider in the horizontal direction. This enables the user to easily change the height and horizontal position of the probe according to actual needs, improving the adaptability and flexibility of the device.

[0040] 3. Convenient manual fine adjustment:

[0041] Handles are respectively provided on the sides of the first slider and the second slider, facilitating manual fine-tuning by the operator and ensuring more precise position adjustment even on the basis of automated adjustment.

[0042] 4. Adjustable clamping system:

[0043] The first clamping plate and the second clamping plate in the first clamping mechanism can be disassembled and repositioned to accommodate stones of different sizes; the second clamping mechanism is also designed as an adjustable structure, and the distance between the third clamping plate and the fourth clamping plate can be adjusted by rotating the third handle, thereby fastening hangers of various specifications. Such a design greatly increases the compatibility of the device with different material sizes.

[0044] 5. Enhanced measurement accuracy:

[0045] The scale or laser ranging mechanism on the side wall of the base provides a reliable reference benchmark, helping to ensure the consistency and accuracy of distance measurement results throughout the calibration process. This is crucial for improving the overall performance of the eddy current ranging sensor.

[0046] 6. Integrated solution:

[0047] The device integrates multiple functional modules (such as two-dimensional adjustment, clamping and fixing, automatic distance adjustment, etc.), forming a complete eddy current ranging sensor calibration system. Compared with traditional decentralized tool combinations, such an integrated design simplifies the operation process, improves work efficiency, and reduces the risk of misoperation.

[0063] Combined with Figures 1 - 3As shown in the figure, the utility model provides a calibration device for an eddy current ranging sensor, including:

[0064] a probe 1, a two-dimensional adjustment mechanism, a first clamping mechanism, a second clamping mechanism, and a distance adjustment mechanism;

[0065] The two-dimensional adjustment mechanism, the first clamping mechanism, the second clamping mechanism, and the distance adjustment mechanism are sequentially arranged on a base 6 from left to right;

[0066] The probe 1 is arranged on the two-dimensional adjustment mechanism. The first clamping mechanism is used for clamping a stone 7, the second clamping mechanism is used for clamping a hanging piece 8, and the distance adjustment mechanism is used for adjusting the position of the second clamping mechanism, so as to change the distance between the stone 7 and the hanging piece 8;

[0073] The probe 1 is installed on the second slider 203;

The height of the probe 1 is adjusted by adjusting the first slider 202 up and down, and the position of the probe 1 in the horizontal direction is adjusted by adjusting the second slider 203 horizontally, so as to adjust the relative position between the probe 1 and the stone 7.

[0075] A first handle 206 is arranged on the side surface of the first slider 202, and a second handle 207 is arranged on the side surface of the second slider 203.

[0076] The first clamping mechanism includes a first clamping plate 301 and a second clamping plate 302;

[0077] The first clamping plate 301 and the second clamping plate 302 clamp the stone material 7 therebetween. The first clamping plate 301 and the second clamping plate 302 are detachably mounted on the base 6 and are used to adjust the distance between the first clamping plate 301 and the second clamping plate 302, facilitating the clamping of stone materials 7 with different thicknesses. Meanwhile, the distance between the first clamping mechanism and the two-dimensional adjustment mechanism is also adjusted.

[0078] The second clamping mechanism includes a third slide rail 401, a third slider 402, a first side plate 403, a first mounting plate 404, a second mounting plate 405, a third clamping plate 406, and a fourth clamping plate 407;

[0079] One third slide rail 401 is respectively arranged on both sides of the base 6 along the length direction. One third slider 402 is arranged on each third slide rail 401, and one first side plate 403 is mounted on each third slider 402;

[0082] The third clamping plate 406 and the fourth clamping plate 407 are mounted in parallel on the top of the second mounting plate 405 and are used to clamp the hanging member 8;

[0083] The first motor 501 drives the first lead screw 502 to rotate, thereby driving the first nut 503 to move, further driving the first mounting plate 404 and the second mounting plate 405 to move, and further driving the third clamping plate 406 and the fourth clamping plate 407 to move.

[0084] A third handle 408 is penetrated through the third clamping plate 406 and the fourth clamping plate 407;

[0085] The outer wall of the third handle 408 is provided with threads. By rotating the handle, the fourth clamping plate 407 is driven to move, thereby adjusting the distance between the third clamping plate 406 and the fourth clamping plate 407 and realizing the clamping of the hanging member 8.

[0086] A scale or a laser distance measuring mechanism is further arranged on the side wall of the base 6 to ensure the accuracy of distance measurement.

[0087] The working steps are as follows:

[0088] Step 1: Select the required clamping device as needed, fix the probe 1 and the object to be measured at corresponding positions, and preliminarily adjust the centering of the probe 1 and the object to be measured.

[0089] Step 2: Fix the left - right position, adjust the probe 1 up and down to find the position with the maximum signal, and determine the vertical alignment; fix the up - down position, adjust the left - right position to find the position with the maximum signal, and determine the horizontal alignment, thus completing the centering of the center point. If it is electrically adjusted, the electric adjustment mechanism can be adjusted according to this logic.

[0090] Step 3: For scenes with obstacles, the obstacles can be fixed first to ensure that the calibration scene matches the site. For direct measurement, this step can be omitted.

[0091] Step 4: Regularly adjust the distance between the target to be measured and the probe 1, record the measured values at different distances, form a curve of the measured values and the distance, and then the calibration of the target to be measured can be completed (the electric mechanism can set the adjustment distance and adjustment delay and automatically record the curve).

[0092] Step 5: Randomly adjust the position of the target to be measured, calculate the distance through the measured value and make a comparison. If they are inconsistent or the deviation is large, repeat Step 4 for secondary calibration until the distance measurement is accurate.

[0093] The principle of the present utility model is as follows:

[0094] Place the stone 7 in the first clamping mechanism, and use the first clamping plate 301 and the second clamping plate 302 to fix the stone 7.

[0095] Adjust the distance between the first clamping plate 301 and the second clamping plate 302 as needed to adapt to stones 7 of different sizes, and ensure that the stone 7 is stably fixed on the base 6.

[0096] Install the hanging piece 8 between the third clamping plate 406 and the fourth clamping plate 407 in the second clamping mechanism, and tighten the hanging piece 8 by rotating the third handle 408.

[0097] Adjustment of the position of the probe 1:

[0098] The probe 1 is installed on the second slider 203 of the two - dimensional adjustment mechanism.

[0099] Use the first handle 206 to move the first slider 202 up and down to adjust the height of the probe 1 so that it maintains an appropriate vertical distance from the surface of the stone 7.

[0100] Use the second handle 207 to move the second slider 203 horizontally to adjust the position of the probe 1 in the horizontal direction to ensure that the probe 1 can accurately contact the designated position of the stone 7.

[0101] Distance adjustment:

[0102] Start the first motor 501 to rotate the first lead screw 502 forward or backward.

[0103] The first nut 503 reciprocates along the axis of the screw as the first screw 502 rotates.

[0104] Since the first nut 503 is fixed to the first mounting plate 404 of the second clamping mechanism, when the first nut 503 moves, it drives the first mounting plate 404 and the second mounting plate 405 connected thereto to move together.

[0105] In this way, the distance between the second clamping mechanism (together with the hanging part 8) and the first clamping mechanism (together with the stone 7) is adjusted.

[0106] Measurement and calibration:

[0107] After adjusting the positions of the stone 7, the hanging part 8 and the probe 1, the calibration of the eddy current distance measuring sensor can be started.

[0108] The scale on the side wall of the base 6 or the laser distance measuring mechanism provides an accurate distance reference to help the operator confirm whether the actual distance meets the expected value.

[0109] According to the actual measurement results, compare with the theoretical values and perform necessary calibration on the eddy current distance measuring sensor.

[0110] The calibration device of the eddy current distance measuring sensor realizes the automatic and precise adjustment of the distance between the stone 7 and the hanging part 8 through the design of a series of precision mechanical structures, and at the same time provides a convenient manual fine-tuning option. This design not only improves the efficiency of the calibration process, but also ensures the reliability of the measurement data.

[0111] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the protection scope of the present invention.
