[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figures 1-6 As shown, the automatic motor rotor appearance inspection device provided in this embodiment includes a workbench 1, a rotor placement platform 2 is arranged at the center of the workbench 1, a camera 3 is arranged above the rear side of the rotor placement platform 2, clamping plates 4 are arranged on both sides of the rotor placement platform 2 on the workbench 1, a chuck 5 is rotatably connected to the inner side of the clamping plate 4, a cylinder 6 is arranged on the outer side of the clamping plate 4, a motor 7 is arranged on the outer side of one side of the clamping plate 4, the output shaft of the motor 7 is fixedly connected to one side of the chuck 5, and a groove 8 is provided on the chuck 5, the groove 8 is an outwardly expanding frustum shape.

[0025] The outwardly expanding frustum-shaped groove 8 on the chuck 5 can accommodate electronic rotors of various specifications.

[0026] Before use, set the height of the rotor placement platform 2 so that the axis of the motor rotor is slightly lower than the axis of the chuck 5.

[0027] In use, the motor rotor is placed on the rotor placement platform 2, and the cylinders 6 on both sides are activated, causing the clamps 5 on both sides to gradually move inward. The two ends of the motor rotor gradually extend into the grooves 8 of the clamps 5. During the extension process, the axis of the motor rotor will gradually move upward until it coincides with the axis of the clamps 5. At this time, the two ends of the motor rotor are firmly clamped, and the bottom surface of the motor rotor will leave the rotor placement platform 2. Then, the motor 7 is started to make the motor rotor rotate. While rotating, the camera 3 continuously takes pictures of the appearance of the motor rotor to complete the automatic detection.

[0028] In this embodiment, as Figure 6 As shown, multiple anti-slip textures 9 are evenly distributed along the circumference of the groove 8 to enhance the ability to transmit rotational torque and prevent detection misalignment caused by slippage.

[0029] In this embodiment, as Figure 1 As shown, the rotor placement platform 2 is a downwardly concave arc-shaped structure, which places the electronic rotor at the center of the rotor placement platform 2, ensuring that the axis of the motor rotor and the axis of the chuck 5 are on the same plane.

[0030] In this embodiment, as Figure 5 As shown, a rack plate 10 passing through the worktable 1 is provided below the rotor placement platform 2. A gear 11 meshes on the rack plate 10. A rotating shaft 12 is provided at the center of the gear 11. Both ends of the rotating shaft 12 are rotatably connected to the worktable 1. A worm gear mechanism 13 is provided at one end of the rotating shaft 12. A rocker arm 14 is provided at one end of the worm of the worm gear mechanism 13.

[0031] Rotating gear 11 causes rack plate 10 to move up and down, thereby adjusting the height of rotor placement platform 2 according to motor rotors of different diameters, so that the axis of motor rotor can be slightly lower than the axis of chuck 5 before clamping.

[0032] The worm gear mechanism 13 ensures that the gear 11 can only rotate when an external force is applied, thus guaranteeing the stability of the structure.

[0033] In this embodiment, as Figure 5 As shown, a movable plate 15 passing through the worktable 1 is provided below the rotor placement platform 2 and spaced apart from the rack plate 10. A slide groove 16 is provided on the outer side of the movable plate 15 along its height direction. A fixed plate 17 is provided below the worktable 1. A slide rail 18 that works with the slide groove 16 is provided on the inner side of the fixed plate 17 along its height direction. The fixed plate 17 moves together with the rack plate 10, making the movement of the rotor placement platform 2 more stable.

[0034] In this embodiment, as Figure 1 As shown, a guide rail 19 is provided on the workbench 1 along its length, and a guide rail groove 20 is provided on the bottom surface of the clamping plate 4, so that the movement of the clamping plate 4 is smoother.

[0035] In this embodiment, as Figure 1 As shown, cylinder fixing blocks 21 are provided at both ends of the workbench 1 to fix the cylinder 6.

[0036] In this embodiment, as Figure 6 As shown, a push plate 22 is provided on the piston rod of cylinder 6, and push columns 23 are provided at both ends of the push plate 22. The push columns 23 are fixed on the outside of the clamping plate 4. The symmetrical force application structure effectively disperses the stress concentration points and ensures the pushing effect.

[0037] In summary, this embodiment achieves automated inspection of the motor rotor's appearance through the coordinated operation of cylinder 6, motor 7, and camera 3. The outwardly expanding frustum-shaped groove 8 on the chuck 5 can accommodate various specifications of motor rotors; combined with the rack plate 10 and gear 11 transmission system, the height of the rotor placement platform 2 can be adjusted. Before inspecting motor rotors of different specifications, height calibration ensures that the motor rotor axis is slightly lower than the axis of the chuck 5, guaranteeing that the motor rotor can detach from the rotor placement platform 2 after secure clamping without interfering with the rotation process.

[0038] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
