Description

Technical Field

[0001] The utility model relates to the technical field of wheel hubs, in particular to a pneumatic drill fixture for machining wheel hubs. Background Art

[0002] The wheel hub is a cylindrical metal part with the inner profile of the tire supporting the tire and the center mounted on the shaft. It is also called a wheel rim, steel rim, wheel, or tire bell. There are many types of wheel hubs depending on the diameter, width, molding method, and material. Before processing the wheel hub, it needs to be fixed first;
