Description

Technical Field

[0001] The present application relates to an automobile steel rim rounding machine. Background Art

[0002] The steel rim is also called the wheel hub. It is a cylindrical metal part that supports the tire with its inner profile. It is a metal part mounted on the shaft in the center. It is also called a wheel rim, steel rim, wheel, or tire bell. Nowadays, the wheel hub of a good car is definitely not small. When modifying a car, the wheel hub is also the first entry point for many people. It not only improves the appearance of the car, but also directly improves the performance of a certain aspect of the car. When the steel rim of a car is out of round, it needs to be repaired by a rounding machine.

[0003] The existing patent publication number CN212760452U discloses a rounding device for automobile steel rims, including a workbench, a functional groove is fixedly opened on the surface of the workbench, the inner wall of the functional groove is circular, the inner wall of the functional groove is slidably connected with a functional disk, the inner bottom wall of the functional groove is fixedly installed with a fixed bearing, the inner ring of the fixed bearing is fixedly connected with a rotating shaft, and one end of the rotating shaft is fixedly connected to the lower surface of the functional disk. The automobile steel rim rounding device is provided with a positioning support device. When in use, the automobile steel rim to be rounded is positioned and fixedly supported by the arc support plate, and the functional disk and the automobile steel rim are driven to rotate by the servo motor, and the rounding roller is pushed by the hydraulic cylinder and the hydraulic rod to round the automobile steel rim, thereby solving the problem that the existing automobile steel rims that fail the out-of-roundness detection need to be re-stamped and repeatedly processed, which increases the production process cost.

[0004] Although the above-mentioned automobile steel rim rounding device has the function of rounding the steel rim, when rounding the steel rim, the steel rim is tightly fixed by the abutment structure, and the rotating structure drives the steel rim and the abutment structure to rotate at the same time. When rounding the steel rim, the contact position between the abutment structure and the steel rim is always fixed, which is not convenient for supporting and rounding different repair positions on the steel rim, resulting in poor rounding effect.

[0005] Therefore, it is hoped to provide an automobile steel rim rounding machine. Utility Model Content
