This bearing device provides stable bearing and can be used for different types of wheel hubs. The above-mentioned technical solution requires manual adjustment of the positions of multiple positioning rods during the positioning process of different models of wheel hubs, which reduces the efficiency of wheel hub positioning and cannot accurately align the wheel hub axis with the platform axis, resulting in a certain deviation in the positioning position and reducing the effect of wheel hub inspection. Therefore, we need to propose a wheel hub bearing device for wheel hub inspection platform. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a wheel hub bearing device for a wheel hub inspection platform, including a platform frame 1, a wheel hub bearing mechanism 2 installed in the inner cavity of the platform frame 1, the wheel hub to be inspected is placed through the wheel hub bearing mechanism 2, and the horizontal angle of the wheel hub bearing mechanism 2 can be adjusted by the platform frame 1 so as to inspect the positioned wheel hub at different angles; The wheel hub bearing mechanism 2 is equipped with a drive mechanism 3 inside. Multiple wheel hub positioning mechanisms 4 are provided on the upper surface of the wheel hub bearing mechanism 2. The drive mechanism 3 drives the multiple wheel hub positioning mechanisms 4 to adjust their positions to position the wheel hub. The multiple wheel hub positioning mechanisms 4 move closer and further away simultaneously, which facilitates the rapid positioning of the wheel hub.

[0016] In this embodiment, the hub bearing mechanism 2 includes a bearing plate 24. The upper surface of the bearing plate 24 is provided with a first slide groove 25 for sliding multiple sets of hub positioning mechanisms 4. The multiple sets of first slide grooves 25 are arranged at equal angles. Each set of first slide grooves 25 is fixedly connected with a guide rod 27 for guiding the hub positioning mechanism 4. A rotating component is installed on the lower surface of the bearing plate 24. The wheel hub bearing mechanism 2 provides a sliding track for the wheel hub positioning mechanism 4 through the first sliding groove 25 on the bearing plate 24. The sliding groove is set at equal angles to adapt to the positioning of wheel hubs of different sizes. The guide rod 27 guides the positioning mechanism to ensure sliding stability. The rotating component can drive the bearing plate 24 to rotate, which facilitates the rotation detection of the wheel hub and improves the detection flexibility.

[0017] Furthermore, the hub positioning mechanism 4 includes a fixed seat 41 slidably disposed on the outside of the guide rod 27. A threaded tube 44 is fixedly connected to the upper surface of the fixed seat 41. A connecting screw 46 is threadedly connected to the threaded tube 44. Lubricating oil is applied between the connecting screw 46 and the threaded tube 44 to prevent corrosion. A positioning rod 45 is fixedly connected to the upper end of the connecting screw 46. Side sliders 43 are fixedly connected to both sides of the fixed seat 41. A second slide groove 26 is provided on both sides of the inner cavity of the first slide groove 25 for the side sliders 43 to slide. In the wheel hub positioning mechanism 4, the fixed seat 41 slides in the second slide groove 26 via the side slider 43, and the guide rod 27 further improves the stability of the sliding. The threaded tube 44 and the threaded connection of the connecting screw 46 allow for quick installation and removal of the positioning rod 45, so that different lengths of positioning rod 45 can be selected for installation according to the width of the wheel hub. The outer side of the mounting rod is provided with a rubber sleeve to prevent the positioning rod 45 from rigidly contacting the wheel hub, thereby avoiding damage to the wheel hub. This mechanism is suitable for wheel hubs of different thicknesses or specifications, improving the versatility of the positioning mechanism.

[0018] Meanwhile, the drive mechanism 3 includes a third motor 31 installed in the middle of the lower surface of the bearing plate 24. The output end of the third motor 31 is connected to a lead screw 32, and the lower end of the lead screw 32 is connected to a hexagonal plate 33. Multiple sets of hinge seats 34 are fixedly connected to the outside of the hexagonal plate 33. A connecting beam 35 is rotatably mounted on each set of hinge seats 34. The bottom of the fixed seat 41 is provided with a mounting groove 42 for the connecting beam 35 to be rotatably mounted. Both ends of the connecting beam 35 are provided with connecting pins (not shown in the figure), which are connected to the hinge seats 34 through the connecting pins. At the same time, the connecting beam 35 is mounted in the mounting groove 42 through the connecting pins. The drive mechanism 3 drives the lead screw 32 through the third motor 31, which moves the hexagonal plate 33. This causes one end of the connecting beam 35 to descend through the hinge seat 34, while the other end of the connecting beam 35 drives the wheel hub positioning mechanism 4 to slide along the first slide groove 25 toward the center of the wheel hub. This enables the synchronous adjustment of multiple wheel hub positioning mechanisms 4, ensuring consistent positioning. The adjustment process is convenient and efficient, and can quickly adapt to the positioning requirements of wheel hubs of different diameters.

[0019] Specifically, the rotating assembly includes a second motor 21 and multiple sets of support legs 23. The output end of the second motor 21 is connected to a rotating seat 22. The multiple sets of support legs 23 are all fixedly connected to the outside of the rotating seat 22, and the upper ends of the multiple sets of support legs 23 are all fixedly connected to the lower surface of the bearing plate 24. The lower end of the lead screw 32 is rotatably mounted on the upper surface of the rotating seat 22. The outside of the lead screw 32 is coated with lubricating oil to reduce driving noise. In the rotating assembly, the second motor 21 drives the bearing plate 24 to rotate stably through the rotating seat 22 and the support leg 23. The support leg 23 enhances the structural strength and bearing stability of the bearing plate 24. The lower end of the lead screw 32 is rotatably mounted on the rotating seat 22 to ensure that the drive mechanism 3 operates synchronously and stably when the bearing plate 24 rotates, without affecting the positioning adjustment function.

[0020] In addition, the platform frame 1 includes a connecting frame 15 for mounting the second motor 21. A reinforcing ring 16 is fixedly connected to the upper end of the connecting frame 15, and a support shaft is fixedly connected to both ends of the connecting frame 15. The connecting frame 15 provides a stable mounting foundation for the second motor 21, while the reinforcing ring 16 enhances the structural strength of the connecting frame 15. The support shaft facilitates the connection between the connecting frame 15 and the support column 13, ensuring the stability of the overall structure.

[0021] Secondly, the platform frame 1 also includes a base plate 11. Two sets of extension plates 12 and two sets of support columns 13 are fixedly connected to the outer side of the base plate 11. The connecting frame 15 is rotatably set on the upper end of the opposite side of the two sets of support columns 13 via two sets of support shafts. A first motor 14 for driving one set of support shafts is installed on one side of one set of support columns 13. The base plate 11, extension plate 12 and support column 13 provide overall support for the device. The extension plate 12 can expand the placement space. The first motor 14 drives the support shaft to rotate the connecting frame 15 and the wheel hub bearing mechanism 2, so as to realize the tilt angle adjustment of the bearing plate 24, which facilitates the detection of the wheel hub from different angles and improves the comprehensiveness of the detection.

[0022] During operation, the wheel hub to be tested is first placed on the bearing plate 24 (at this time, multiple wheel hub positioning mechanisms 4 are close to the center of the bearing plate 24). The third motor 31 of the drive mechanism 3 is started, and the hexagonal plate 33 is moved upward through the lead screw 32. During the upward movement of the hexagonal plate 33, the fixed seat 41 of the multiple wheel hub positioning mechanisms 4 is pushed to slide along the first slide groove 25 through the connecting beam 35. At the same time, the stability of the movement is further ensured by the guidance of the guide rod 27 and the side slider 43, so that the rubber sleeve on the outside of the positioning rod 45 abuts against the inner wall of the wheel hub, thereby achieving accurate positioning of the wheel hub. If different circumferential angles of the wheel hub need to be detected, the second motor 21 drives the bearing plate 24 to rotate through the rotating seat 22 and the support leg 23. If the detection tilt angle needs to be adjusted, the first motor 14 drives the support shaft to rotate, causing the connecting frame 15 and the wheel hub bearing mechanism 2 to tilt, thereby achieving stable bearing and detection adaptation of the wheel hub in multiple directions and angles.
