Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 3 In the embodiment of the present invention, a wheel hub detection and identification device includes a fixed bottom plate 1. A fixing hole is provided on the fixed bottom plate 1, and the fixing hole can be fixed to the ground through bolts. The top surface of the fixed bottom plate 1 is fixedly connected with a column 2. The top end of the column 2 is rotatably connected with a guide groove 3. A cantilever 4 adapted to it is slidably connected in the guide groove 3. One end of the cantilever 4 is fixedly connected with a counterweight seat 5. The other end of the cantilever 4 slidably penetrates a guide rod 6. A round hole for the guide rod 6 to penetrate and slide is provided on the cantilever 4. The bottom end of the guide rod 6 is fixedly connected with a connecting frame 7. The middle part of the top surface of the connecting frame 7 is fixedly connected with a threaded rod 8. The threaded rod 8 movably penetrates the cantilever 4. A round hole for the threaded rod 8 to penetrate and move is provided on the cantilever 4. A threaded sleeve 9 adapted to it is sleeved on the outer side of the threaded rod 8. The threaded sleeve 9 is rotatably connected to the top surface of the cantilever 4. A first gear 10 is fixedly connected to the threaded sleeve 9. A second gear 11 meshing and driving with the first gear 10 is provided on the outer side of the first gear 10. A first motor 12 is fixedly installed on the bottom surface of the cantilever 4 corresponding to the second gear 11.

The bottom of the connecting frame 7 is connected with a connecting plate 13. A wheel hub 14 is provided below the connecting plate 13.

[0022] The hub 14 is connected and detected through the connecting plate 13. Driven by the first motor 12, the first gear 10 and the second gear 11 cooperate with the threaded sleeve 9 to drive the threaded rod 8, so as to drive the connecting plate 13 to lift and adjust through the guide rod 6. At the same time, the cantilever 4 can rotate at the top of the column 2 through the guide groove 3, and the cantilever 4 can slide in the guide groove 3, so as to adjust the position, so that the connecting plate 13 can be easily brought close to and corresponding to the hub 14. There is no need to carry the hub 14 to the workbench, and only the connection between the connecting plate 13 and the hub 14 needs to be operated, effectively reducing the working intensity.

[0023] The cantilever 4 can rotate at the top of the column 2 through the guide groove 3, and the cantilever 4 can slide in the guide groove 3, so as to adjust the position. Thus, after detecting the hub 14, the hub 14 can be carried, which is convenient for separating the stacked hubs and detecting and stacking them again.

[0024] A rotating seat 15 is rotatably penetrated through the middle of the connecting plate 13 corresponding to the mounting hole of the hub 14. A positioning column 16 is fixedly connected to the bottom surface of the rotating seat 15 corresponding to the mounting hole of the hub 14, and the positioning column 16 is inserted into the mounting hole on the hub 14.

[0025] A third gear 17 is fixedly connected to the outer side of the top of the rotating seat 15. A fourth gear 18 meshing with the third gear 17 is arranged outside the third gear 17. A second motor 19 is fixedly installed on the connecting plate 13 corresponding to the fourth gear 18. The output end of the second motor 19 rotatably penetrates through the connecting plate 13 and is fixedly connected to the fourth gear 18.

[0026] A plurality of guide rods 21 are fixedly connected in parallel in the movable cavity 20 opened on the circumference of the rotating seat 15. A hook member 22 is slidably connected to the corresponding guide rods 21 in common. A plurality of tension springs 23 are fixedly connected between the hook member 22 and the movable cavity 20 evenly.

[0027] The bottom end of the hook member 22 extends to the inner side of the hub 14, the hook member 22 hooks on the hub 14, and the top end of the hook member 22 extends out of the top surface of the rotating seat 15.

[0028] On the top surface of the connecting plate 13, sliding grooves 24 are symmetrically and fixedly connected to both sides of the hub 14. A sliding rod 25 adapted to the sliding grooves 24 is slidably connected in the sliding grooves 24. A connecting piece 26 is fixedly connected to the top end of the sliding rod 25. An electric push rod 27 is provided between the connecting piece 26 and the connecting plate 13. The electric push rod 27 is fixedly installed on the connecting plate 13. The telescopic end of the electric push rod 27 is fixedly connected to the connecting piece 26. A laser rangefinder 28 is fixedly connected to the bottom of the sliding rod 25 and the side close to the hub 14. The first motor 12, the second motor 19, the electric push rod 27, and the laser rangefinder 28 are all electrically connected to an external controller through wires. The controller is externally connected to a power supply. The controller can control the working states of the first motor 12, the second motor 19, the electric push rod 27, and the laser rangefinder 28, and can also display and calculate the measurement data of the laser rangefinder 28. The distance between the laser rangefinders 28 is fixed. Subtracting the measurement values of the two laser rangefinders 28 from this fixed distance is the diameter of the hub 14, and the roundness of the hub 14 can be judged by the change of the measurement values of the laser rangefinder 28.

[0029] The hook member 22 is pulled by the tension spring 23 to slide on the guide rod 21, so that the hook member 22 penetrates through the hub 14 from the central hole of the hub 14 and hooks the hub 14. At the same time, the rotation of the hub 14 is limited by the positioning column 16, so that the hub 14 can be driven to rotate by the second motor 19. Further, the laser rangefinder 28 is driven to move up and down by the electric push rod 27, so as to connect and comprehensively detect and identify the hub 14, and detect whether the diameter and roundness of the hub are qualified.

[0030] The working principle of the present utility model is:

[0031] During use, the device is fixed through the fixed base plate 1, slides through the cantilever 4 in the guide groove 3, and the guide groove 3 rotates at the top of the column 2, so as to control the correspondence between the connecting plate 13 and the wheel hub 14. At this time, the first motor 12 is started, and the first gear 10 and the second gear 11 cooperate to drive the rotation of the threaded sleeve 9. The threaded rod 8 drives the lifting of the connecting frame 7 in cooperation with the guide rod 6, so as to control the correspondence between the connecting plate 13 and the stacked wheel hubs 14 placed on the ground. At this time, the hook member 22 is toggled towards the middle, so that the rotating seat 15 fits with the wheel hub 14, and the positioning post 16 is further inserted into the mounting hole of the wheel hub 14. The hook member 22 is released and slides along the guide rod 21 under the action of the tension spring 23, so that the hook member 22 hooks on the wheel hub 14, and the wheel hub 14 is connected to the bottom end of the rotating seat 15. At this time, the wheel hub 14 can be suspended by the drive of the first motor 12. Further, the second motor 19 is started, and the third gear 17 and the fourth gear 18 cooperate to drive the rotation of the rotating seat 15, so that the fixed wheel hub 14 rotates. Furthermore, the wheel hub 14 is detected by the laser rangefinder 28. At the same time, the electric push rod 27 can be started, and the connecting piece 26 drives the sliding rod 25 to descend along the chute 24, so that the laser rangefinder 28 detects different height positions of the wheel hub 14, making the detection comprehensive. After the detection is completed, the wheel hub 14 is further transported away from the stacking position placed in the completion area for stacking by sliding the cantilever 4 in the guide groove 3, and the guide groove 3 rotates at the top of the column 2.
