Description

Technical Field

[0001] This application relates to the field of rotary fixture technology, specifically a rotary fixture for lightweight automotive wheel hub processing. Background Technology

[0002] A wheel hub (CarRim) is the part at the center of a wheel where the axle is mounted; it is commonly referred to as a "wheel rim" or "steel rim." Car wheel hubs are an important component of automotive parts. Along with the growth of China's automotive parts industry, the wheel hub industry has gradually developed and expanded. Fixtures are required during wheel hub processing.

[0003] In the existing technology, when processing wheel hubs, it may be necessary to process both sides of the wheel hub. When processing the other side, the existing technology usually requires disassembling the wheel hub and then reinstalling it to process the other side. In addition, when fixing the wheel hub, multiple sets of clamping components are set up, and each clamping component needs to be adjusted separately when adjustment is required, which is quite troublesome. Therefore, there is a need for a lightweight rotary fixture for processing automotive wheel hubs. Utility Model Content

[0006] By adopting the above technical solution, when it is necessary to process the other side of the wheel hub, an external power source can be activated to drive the rotating shaft to rotate, which in turn drives the mounting ring to rotate, making it easier to process the other side of the wheel hub.

[0007] Optionally, the clamping mechanism includes an active hinge rod, the other end of which is hinged to a support roller, and a driven hinge rod is hinged to the support roller.

[0008] By adopting the above technical solution, when the active hinge rod rotates, it will drive the support roller to move, thereby driving the driven hinge rod to rotate.

[0009] Optionally, the mounting ring is provided with a sliding groove, a sliding block is slidably mounted on the sliding groove, and a driven hinge rod is hinged to the sliding block.

[0010] By adopting the above technical solution, the driven hinge rod can slide on the sliding groove.

[0012] By adopting the above technical solution, rotating the rotating ring can drive the rack to rotate.

[0013] Optionally, a connecting shaft is fixedly mounted on the active hinge rod, and a small gear is fixedly mounted on the connecting shaft through the side wall of the mounting ring, wherein the small gear and the rack mesh with each other.

[0014] By adopting the above technical solution, when the rack rotates, it will drive the small gear to rotate, which in turn will drive the connecting shaft to rotate, thereby driving the active articulating rod to rotate.

[0015] Optionally, the fixing mechanism includes a fixing frame, which has a threaded hole, a threaded rod is threadedly installed in the threaded hole, and a knob is fixedly installed on the threaded rod.

[0016] By adopting the above technical solution, when fixing is required, the knob can be turned, thereby driving the threaded rod to rotate, which in turn drives it to move.

[0017] Optionally, the fixing hole is a threaded hole, and the size of the fixing hole is the same as the size of the threaded rod.

[0018] By adopting the above technical solution, it is easy to fix the rotating ring by fixing the fixing hole through the threaded rod.

[0019] Optionally, anti-slip grooves are provided at equal intervals on the outer side of the support roller.

[0020] By adopting the above technical solution, the friction between the support roller and the outer side of the hub is increased, thereby facilitating the rotation of the hub.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application, by setting up an easily adjustable support roller, can conveniently adjust the hubs of different sizes when they need to be fixed. By setting up a rotating shaft, it is easy to adjust when the other side of the hub needs to be processed. The various structures cooperate with each other, saving time and making it more efficient.

[0029] Please see Figure 1-4 This application provides a technical solution: a lightweight automotive wheel hub machining rotary fixture, including a mounting frame 1, a rotating shaft 2 rotatably mounted on the mounting frame 1, an external power supply connected to the rotating shaft 2, a mounting ring 3 fixedly mounted on the rotating shaft 2, a mounting plate 4 hinged to the mounting ring 3, the mounting plate 4 being a telescopic plate, a small motor 5 fixedly mounted on the mounting plate 4, and a clamping mechanism and a fixing mechanism 6 provided on the mounting ring 3. When it is necessary to process the other side of the wheel hub, the external power supply can be activated, thereby driving the rotating shaft 2 to rotate, thereby driving the mounting ring 3 to rotate, facilitating the processing of the other side of the wheel hub.

[0030] In the technical solution of this application, such as Figure 1 As shown, the clamping mechanism includes an active hinge rod 8, with a support roller 9 hinged to the other end of the active hinge rod 8. A driven hinge rod 10 is hinged to the support roller 9. When the active hinge rod 8 rotates, it will drive the support roller 9 to move, thereby driving the driven hinge rod 10 to rotate.

[0031] In the technical solution of this application, such as Figure 2 As shown, a sliding groove 11 is provided on the mounting ring 3, a sliding block is slidably installed on the sliding groove 11, and a driven hinge rod 10 is hinged on the sliding block, which can slide on the sliding groove 11.

[0032] In the technical solution of this application, such as Figure 1 and 4As shown, a rotating ring 7 is slidably mounted on the mounting ring 3. A rack 15 is provided on the rotating ring 7. A fixing hole 17 is provided on the rotating ring 7. When the rotating ring 7 is rotated, the rack 15 can be driven to rotate.

[0033] In the technical solution of this application, such as Figure 1 and 4 As shown, a connecting shaft is fixedly installed on the active hinge rod 8. A small gear 16 is fixedly installed on the connecting shaft through the side wall of the mounting ring 3. The small gear 16 and the rack 15 mesh with each other. When the rack 15 rotates, it will drive the small gear 16 to rotate, thereby driving the connecting shaft to rotate, and thus driving the active hinge rod 8 to rotate.

[0034] In the technical solution of this application, such as Figure 3 As shown, the fixing mechanism 6 includes a fixing frame 12, which has a threaded hole. A threaded rod 14 is threadedly installed in the threaded hole, and a knob 13 is fixedly installed on the threaded rod 14. When fixing is required, the knob 13 can be rotated, thereby driving the threaded rod 14 to rotate, which in turn drives it to move.

[0035] In the technical solution of this application, such as Figure 1 and 3 As shown, the fixing hole 17 is a threaded hole, and the size of the fixing hole 17 is the same as the size of the threaded rod 14, so as to fix the fixing hole 17 through the threaded rod 14, thereby fixing the rotating ring 7.

[0036] In the technical solution of this application, such as Figure 1 As shown, anti-slip grooves are provided at equal intervals on the outer side of the support roller 9 to increase the friction between the support roller 9 and the outer side of the hub, thereby facilitating the rotation of the hub.

[0037] During clamping, the hub is placed at the center of the device, and then the rotating ring 7 is rotated. When the rotating ring 7 is rotated, the rack 15 is rotated, which in turn drives the small gear 16 to rotate, thereby driving the connecting shaft to rotate, which in turn drives the active hinge rod 8 to rotate. When the active hinge rod 8 rotates, it drives the support roller 9 to move, which in turn drives the driven hinge rod 10 to rotate. This allows the position of the support roller 9 to be adjusted to accommodate hubs of different sizes. When the hub needs to be rotated, the small motor 5 is started, which drives the support roller 9 to rotate, thereby driving the hub to rotate. This makes it easier to adjust the processing position when needed. When the other side of the hub needs to be processed, an external power supply can be started, which drives the rotating shaft 2 to rotate, which in turn drives the mounting ring 3 to rotate, facilitating the processing of the other side of the hub.
