Description

Technical Field

[0001] This utility model relates to the field of automotive wheel hub processing technology, specifically a polishing device for lightweight automotive wheel hub processing. Background Technology

[0002] A wheel rim is a cylindrical metal component mounted on an axle that supports the tire. It is also called a wheel rim, steel rim, wheel hub, or tire rim. Wheel rims come in many varieties depending on their diameter, width, molding method, and materials.

[0003] A search revealed that utility model patent publication number CN 215092865 U discloses a polishing device for automobile wheel hub processing, relating to the field of automobile wheel hub processing technology. This device addresses the issue of handheld polishing equipment moving along the rim of the automobile wheel hub to polish it. However, this method requires highly skilled operators, and variations in the contact force between the polishing equipment and the wheel hub can lead to issues with polishing accuracy. The device has a first column and a second column above its base, both connected to the base by screws. A lifting device is located between the first and second columns, with a first polishing head positioned above it. A rotating rod is located on one side of the first column, with a tenon joint at one end, forming a single unit with the rotating rod. A second polishing head is located on one side of the second column.

[0004] Existing automotive wheel rims can only be polished on one side at a time, not both sides simultaneously, which reduces work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight polishing device for processing automotive wheel hubs, which solves the problem mentioned in the background art that automotive wheel hubs can only be polished on one side and cannot be polished on both sides at the same time, thus reducing work efficiency.

[0006] This application provides a polishing device for lightweight automotive wheel hub processing, including a polishing body. A rotating assembly is rotatably connected inside the polishing body. A first rotating disk and a second rotating disk are fixedly connected to the upper and lower parts of the rotating assembly. A limiting assembly is fixedly connected inside the rotating assembly. A drive roller and a rotating roller are rotatably connected inside the limiting assembly to provide a transmission connection to the wheel hub body.

[0007] By adopting the above technical solution, the wheel hub body is placed on the drive roller, and then the third and second electric telescopic rods are driven to push the push frame. The push frame pushes the rotating roller to clamp the wheel hub body. After the wheel hub body is clamped, the first electric telescopic rod drives the polishing disc of the polishing machine to polish the surface of the wheel hub body. At the same time, the second motor drives the drive roller to rotate, and the drive roller drives the wheel hub body to rotate, ensuring that the surface of the wheel hub body is polished. When the surface of the wheel hub body is polished, the limit bolt is pulled out from the fixed frame, and then the first motor drives the second rotating disc to rotate. The second rotating disc drives the fixed frame wheel hub body to rotate 180 degrees, ensuring that the other side of the wheel hub body is polished. Then the limit bolt is inserted into the fixed frame to prevent the wheel hub body from shaking during the polishing process.

[0008] Optionally, it also includes a polishing assembly and a connecting plate. A first electric telescopic rod is fixedly connected inside the connecting plate. A polishing machine is fixedly connected to the telescopic end of the first electric telescopic rod. A polishing disc is fixedly connected to the output end of the polishing machine to polish the surface of the wheel hub body.

[0009] By adopting the above technical solution, the wheel hub is polished to enhance its overall practicality.

[0010] Optionally, both ends of the rotating drum are rotatably connected to a push frame, the outer wall of the push frame is fixedly connected to the telescopic ends of the second and third electric telescopic rods, and the other end of the drive drum is fixedly connected to a second motor.

[0011] By adopting the above technical solution, the wheel hub is driven to rotate, ensuring that the wheel hub can be polished quickly.

[0012] Optionally, a fixed frame is fixedly connected inside the rotating assembly, and the fixed frame is fixedly connected to the first rotating disk and the second rotating disk, and a first motor is fixedly connected to the lower part of the second rotating disk.

[0013] By adopting the above technical solution, the wheel hub is rotated, and both sides of the wheel hub are polished.

[0014] Optionally, a limiting groove is provided inside the fixed frame and the polishing body.

[0015] By adopting the above technical solution, it is easier to insert the limit bolt and avoid the wheel hub from shaking during the polishing process.

[0016] Optionally, the connecting plate of the polishing assembly has a fixing groove inside, and the fixing groove of the connecting plate is fixedly connected to the fixing end of the first electric telescopic rod.

[0017] The first electric telescopic pole is fixed by adopting the above technical solution.

[0018] Optionally, there are three sets of rotating rollers, with the three sets of rotating rollers surrounding each other around the center of the hub body.

[0019] By adopting the above technical solution, the rotation of the wheel hub is guaranteed.

[0020] Optionally, the polishing body has an internal movable connection of a limit bolt, and the pull head of the limit bolt is provided with an anti-slip layer.

[0021] By adopting the above technical solution, the limiting bolt limits the fixed frame, thereby enhancing the overall practicality.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This technical solution involves placing the wheel hub body on a drive roller, then driving a third and second electric telescopic rod to push a push frame. The push frame pushes a rotating drive roller to clamp the wheel hub body. Once the wheel hub body is clamped, a first electric telescopic rod drives a polishing disc to polish the surface of the wheel hub body. Simultaneously, a second motor drives the drive roller to rotate, which in turn rotates the wheel hub body, ensuring that the surface of the wheel hub body is polished. After the surface of the wheel hub body is polished, a limit bolt is pulled out from the fixed frame. Then, a first motor drives a second rotating disc to rotate, which in turn rotates the fixed frame and the wheel hub body 180 degrees, ensuring that the other side of the wheel hub body is polished. Finally, a limit bolt is inserted into the fixed frame to prevent the wheel hub body from shaking during the polishing process. The rotating assembly ensures double-sided polishing of the wheel hub, improving polishing efficiency. Attached Figure Description
