[0003] In the current field of new energy eddy current sensor testing technology, electromagnetic interference in eddy current sensor testing is difficult to eliminate, and there are problems with compatibility with various products and insufficient equipment flexibility and accuracy. For testing equipment, true four-axis adjustability is not possible, and equipment stability is not high, especially as it cannot be used for sharing with different products. Utility Model Content

[0004] To address the aforementioned issues, this application provides a reasonably structured eddy current sensor testing device, which is compatible with the testing and installation of different models of eddy current sensors, meets various testing requirements, and offers high flexibility in use.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An eddy current sensor testing device includes a working platform with a support mounted on the platform via a support column. The support has a box-like structure. An XYZR adjustment platform is mounted on the working platform outside the support. A stator support is mounted on the output part of the XYZR adjustment platform, and the stator support is located above the support. The device also includes a rotor support mounted vertically through the middle of the support. The rotor of the eddy current sensor is mounted on a rotor fixture, which is mounted on the rotor support.

The output end of the motor faces upward and a rotating shaft is mounted on it via a coupling. A rotating disk is fitted on the rotating shaft, and the rotating shaft and the rotating disk constitute a rotor support.

[0009] The rotating disk is housed inside the support.

[0010] The support has a central hole on its top surface, which is located above the rotating disk.

[0011] The upper edge of the front end of the support is provided with an opening. The XYZR adjustment platform is installed behind the support. The stator support includes a cantilever plate installed on the XYZR adjustment platform at the rear end. A support pin is installed with the front end of the cantilever plate facing downward.

[0012] The support pin passes through the cantilever plate from top to bottom, and a clamping structure is installed on the bottom surface of the cantilever plate to hold and clamp the support pin.

[0013] The bottom end of the support pin is a convex spherical structure, which is supported on the inner bottom surface of the support through the contact of the convex spherical structure.

[0014] A through hole is provided in the middle of the cantilever plate.

[0034] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown, an eddy current sensor testing device according to this embodiment includes a working platform 1, on which a support 3 is mounted via a support column 2. The support 3 has a box-like structure. An XYZR adjustment platform 5 is mounted on the working platform 1 located outside the support 3. A stator support 4 is mounted on the output part of the XYZR adjustment platform 5, and the stator support 4 is located above the support 3. It also includes a rotor support 6 that is installed vertically through the middle of the support 3. The rotor of the eddy current sensor is mounted on a rotor fixture 82, which is mounted on the rotor support 6. The stator of the eddy current sensor is mounted on a stator fixture 81, which is mounted on the stator support 4.

[0036] In this embodiment, during use, corresponding stator fixtures 81 and rotor fixtures 82 can be installed on the stator support 4 and rotor support 6 as needed to match the testing and installation of different types of eddy current sensors. The operation of the XYZR adjustment platform 5 can be used to easily adjust the stator fixtures 81 and rotor fixtures 82 to be on the same axis. The position and angle of the stator relative to the rotor of the eddy current sensor can also be adjusted in real time during testing to meet different testing requirements.

[0037] like Figure 3 As shown, a motor base 71 is mounted on the bottom surface of the support 3, and a motor 7 is mounted on the bottom surface of the motor base 71. The output end of the motor 7 faces upward and a rotating shaft 61 is mounted on it via a coupling. A rotating disk 62 is fitted on the rotating shaft 61. The rotating shaft 61 and the rotating disk 62 constitute the rotor support 6.

[0038] In this embodiment, the support 3 with a box structure effectively ensures the structural reliability of the rotor support 6, which helps to ensure the test results.

[0039] The rotating disk 62 is housed inside the support 3.

[0040] In this embodiment, the overall structure of the testing equipment is arranged using a box-shaped support 3. The rotating disk 62 is housed inside the support 3, and the rotor is installed above the rotating disk 62 via the rotor tool 82. The stator is installed on the stator support 4 above the support 3 via the stator tool 81. This allows the stator and rotor to be installed separately during testing, effectively ensuring and maintaining the positional structural relationship between the stator and rotor during testing.

[0041] The support 3 has a central hole 32 on its top surface, which is located above the rotating disk 62, facilitating the installation of the rotor tooling 82 and the rotor.

[0042] The support 3 has an opening 31 on its upper front edge. The XYZR adjustment platform 5 is installed behind the support 3. Figure 4 As shown, the stator support 4 includes a cantilever plate 41 mounted on the XYZR adjustment platform 5 at its rear end. A support pin 42 is mounted on the front end of the cantilever plate 41 facing downward. The bottom end of the support pin 42 passes through the opening 31 downward and is supported on the inner bottom surface of the support 3.

[0043] In this embodiment, the cantilever plate 41 in the stator support 4 is installed on the output part of the XYZR adjustment platform 5 in a cantilever structure. By installing the support pin 42 on the cantilever plate 41 which is far away from the XYZR adjustment platform 5, the cantilever end of the cantilever plate 41 can be reliably supported by the support pin 42, which effectively ensures the structural stability of the stator support 4 and ensures the reliability and consistency of the test.

[0044] The support pin 42 passes through the cantilever plate 41 from top to bottom, and a clamping structure is installed on the bottom surface of the cantilever plate 41 to hold and clamp the support pin 42.

[0045] In this embodiment, the height and position of the cantilever end of the cantilever plate 41 relative to the inner bottom surface of the support 3 can be quickly and conveniently adjusted via the support pin 42 combined with the clamp structure, according to equipment maintenance or actual testing needs.

[0046] The bottom end of the support pin 42 is a convex spherical structure, which is supported on the inner bottom surface of the support 3 through the contact of the convex spherical structure.

[0047] In this embodiment, the bottom end of the support pin 42 is set as an outwardly convex spherical structure, so that the stator support 4 can rotate relative to each other within a certain range under the drive of the XYZR adjustment platform 5. The outwardly convex spherical structure ensures the support of the cantilever end of the stator support 4, effectively meeting the testing requirements while ensuring structural and testing reliability.

[0048] A through hole 441 is provided in the middle of the cantilever plate 41 to facilitate the installation of the rotor tooling 82 and the rotor, as well as the matching of the rotor and the stator after testing.

[0049] The structure of the XYZR adjustment platform 5 is as follows: it includes an XYZ three-axis platform 51 horizontally mounted on the work platform 1, an L-shaped movable seat 52 mounted on the top output part of the XYZ three-axis platform 51, a rotation drive power 53 mounted on the side of the movable seat 52, and a stator support seat 4 mounted on the side output part of the rotation drive power 53.

[0050] In this embodiment, the stator support 4 is moved and adjusted in the X, Y, and Z directions by the operation of the XYZ three-axis platform 51; the stator support 4 is driven to rotate in the vertical plane by the rotation drive power 53 to achieve angle adjustment.

[0051] In this embodiment, the XYZ three-axis platform 51 can adopt the structure of an existing conventional three-axis platform, which can perform the required movement and adjustment in the X, Y, and Z directions for testing.

[0052] The rotation drive 53 can be a commercially available standard product, such as a rotary table, which can drive the stator support 4 to rotate within a certain preset angle.

[0053] In this embodiment, corresponding tooling components 8 can be provided according to the structural requirements of the stator and rotor in the eddy current sensor, such as... Figure 5 , Figure 6 , Figure 7As shown, the stator is installed by the corresponding stator fixture 81, and the rotor is installed by the corresponding rotor fixture 82. Then, the stator fixture 81 is installed and fixed on the stator support 4, and the rotor fixture 82 is installed and fixed on the rotor support 6. The motor 7 works, and in conjunction with the work of the XYZR adjustment platform 5, the test between the rotor and the stator is carried out.

[0054] In this embodiment, a positioning pin for aligning the stator tooling 81 can be installed on the stator support 4, and a threaded hole for locking and fixing the stator tooling 81 can be opened, which facilitates the installation and matching of different stator tooling 81.

[0055] In this embodiment, the rotor tooling 82 is mounted on the rotating shaft 61. Depending on actual needs, the rotor tooling 82 can also be fixed to the rotating disk 62 using fasteners, etc., to achieve the installation and matching of the rotor tooling 82 on the rotor support seat 6.

[0056] In this embodiment, the testing equipment is housed in a shielded protective chamber, all workpieces are demagnetized, and communication is achieved using test cables to reduce or even avoid electromagnetic interference during testing.

[0057] In this embodiment, the rotor support 6 can be manufactured using traditional spindle technology, effectively ensuring that its runout tolerance is 0.005mm.

[0058] The testing equipment in this embodiment is used for testing eddy current sensors. Combined with the settings of corresponding sensors and other data collection terminals, it can perform parameter tests including pole pair number, harmonic amplitude, amplitude fluctuation, etc.

[0059] The method of using this utility model is as follows:

[0060] The position and orientation of the stator support 4 are adjusted by the XYZR adjustment platform 5 so that the stator support 4 is located at the same axis position relative to the rotor support 6; the rotor is installed on the corresponding rotor fixture 82, and the rotor fixture 82 is installed on the rotor support 6; the stator is installed on the corresponding stator fixture 81, and the stator fixture 81 is installed on the stator support 4, thus completing the installation of the fixture assembly 8 on the test equipment.

[0061] When motor 7 is working, the test is initiated. During the test, the position and angle of the stator tooling 81 and the stator can be adjusted via the stator support seat 4 through the XYZR adjustment platform 5 according to the actual test requirements.

[0062] This invention can be matched with the testing and installation of different models of eddy current sensors, meeting different testing needs, effectively ensuring testing efficiency, improving product compatibility, and offering high flexibility in use.
