Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, in particular to a wheel hub oblique hole drilling device. Background Art

[0002] The wheel hub is a cylindrical metal part with the inner contour of the tire supporting the tire, and the center is mounted on the shaft. It is also called a wheel rim, steel rim, wheel, or tire bell. The main function of the wheel hub is to bear the overall weight of the car. Whether the wheel hub is intact represents whether the car can run normally and the safety during driving. There are many types of wheel hubs according to diameter, width, molding method, and material. According to the characteristics and needs of different models, the wheel hub surface treatment process will also adopt different methods. Generally, there are inclined holes on the wheel hub. On the one hand, it is for the consideration of reducing weight and heat dissipation. By designing the inclined holes, the weight of the wheel hub can be reduced. On the other hand, the inclined holes also help to dissipate heat and prevent the wheel hub from being damaged due to overheating.

[0003] The traditional method of drilling inclined holes in wheel hubs often relies on manual operation, which is not only inefficient but also difficult to ensure accuracy. It is prone to problems such as inclined hole position deviation and inconsistent hole diameter. For wheel hubs that need to be drilled in a circular array of inclined holes, the traditional drilling method is even more difficult to achieve uniform and equidistantly distributed inclined holes, further increasing the manufacturing difficulty and cost. For this reason, we propose a wheel hub inclined hole drilling device. Utility Model Content
