[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] Please see Figures 1 to 3 This utility model provides a device for mounting a brake disc on a wheel hub, including a frame 10, a limiting fixture 20, and a mounting sleeve 30. The limiting fixture 20 is used to fit the wheel hub and the brake disc together, and the mounting sleeve 30 is used to tighten the bolts and nuts, thus completing the connection between the wheel hub and the brake disc.

[0029] Specifically, the limiting fixture 20 includes a fixture plate 21 and limiting rods 22. The fixture plate 21 is movably mounted on the frame 10. Multiple limiting rods 22 are located on the side of the fixture plate 21 away from the frame 10 and are distributed circumferentially to form a shape and size that fits the wheel hub. A sliding groove is also formed on the limiting rod 22 along the axial direction, and a slidingly connected support rod 221 is connected within the groove via a spring. The support rod 221 is positioned inward to fit against the wheel hub. Multiple mounting sleeves 30 are distributed circumferentially on the side of the fixture plate 21 away from the frame 10 and are rotatably connected to the fixture plate 21.

[0030] The wheel hub to be installed is placed between multiple limiting rods 22, which limit the wheel hub. Then, the tooling plate 21 moves relative to the frame 10, moving towards the brake disc on the workstation, so that the wheel hub and brake disc are in contact, and the drive axle bolts pass through the through holes of the wheel hub. Simultaneously, the nuts in the multiple mounting sleeves 30 are aligned with the bolts, and rotating the mounting sleeves 30 connects the nuts and bolts, thus completing the connection between the wheel hub and brake disc. This significantly improves work efficiency and reduces manual labor. When tightening the nuts, the tooling plate 21 continues to move towards the brake disc, allowing the mounting sleeves 30 to move axially. The support rod 221, under the action of a spring, presses against the wheel hub, maintaining the contact between the wheel hub and brake disc.

[0031] Specifically, the frame 10 is equipped with a cylinder 11, which is connected to the tooling plate 21. The cylinder 11 can push the tooling plate 21 to move and bring the wheel hub into contact with the brake disc. When tightening the nut, it can also push the tooling plate to move the sleeve forward.

[0032] Specifically, the limiting fixture 20 also includes positioning rods 23. Multiple positioning rods 23 are located on the side of the fixture plate 21 away from the frame 10 and can be inserted between the spokes of the wheel hub. The positioning rods 23 are used to position the circumferential position of the wheel hub when inserted into the spokes, thereby ensuring that the through hole of the wheel hub is aligned with the through hole of the brake disc before installation, allowing bolts to pass directly through the through hole of the wheel hub.

[0033] The tooling plate 21 is also provided with multiple through slots 211 circumferentially. The end of the positioning rod 23 passes through the through slot 211 and is threaded. The portions of the positioning rod 23 located on both sides of the through slot 211 are threaded with locking nuts 231. Depending on the spokes of different wheel hubs, the positioning rod 23 can be moved within the through slot 211 to adjust its position. Then, the locking nuts 231 are tightened on both sides to fit the tooling plate 21, thus completing the fixation.

[0034] A motor 24 is located on the side of the tooling tray 21 near the frame 10. The output shaft of the motor 24 is connected to a drive gear 241. The ends of the mounting sleeves 30 all pass through the tooling tray 21 and are equipped with driven gears 31. The drive gear 241 is located at the center of multiple driven gears 31 and meshes with all the driven gears 31. By driving the drive gear 241 to rotate through the motor 24, the multiple driven gears 31 can be driven to rotate, thereby driving the mounting sleeves 30 to rotate, connecting the nut and bolt, and completing the installation of the wheel hub and brake disc.

[0035] The working principle of the above-mentioned wheel hub brake disc mounting device is as follows: the wheel hub to be installed is placed between multiple limiting rods 22, and the circumferential position of the wheel hub is limited by the positioning rod 23 (e.g., Figure 4(As shown), the cylinder 11 is then activated to move the tooling plate 21 toward the brake disc on the workstation, so that the wheel hub and brake disc are in contact, and the bolts of the drive axle pass through the through holes of the wheel hub. At the same time, multiple mounting sleeves 30 are aligned with each bolt, and the motor 24 is activated to drive the mounting sleeves 30 to rotate, so that the nuts are threadedly connected to the bolts, thereby completing the connection between the wheel hub and the brake disc. When tightening the nuts, the cylinder 11 pushes the tooling plate 21 to move forward continuously, and the support rod 221 on the limit rod 22 is in contact with the wheel hub, maintaining the contact between the wheel hub and the brake disc under the action of the spring.

[0036] Using the above-mentioned wheel hub brake disc mounting device, the wheel hub only needs to be placed on the tooling plate, and the device can automatically complete the installation of the brake disc. This not only greatly improves work efficiency and reduces manual labor, but also can be applied to different styles of wheel hubs.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
