Description

Technical Field

[0001] The utility model relates to the technical field of positioning structures, in particular to a hub processing positioning structure for aluminum alloy hub production. Background Art

[0002] The wheel hub is a cylindrical metal part with the inner profile of the tire supporting the tire, and the center is mounted on the shaft. It is also called a wheel rim, a steel rim, a wheel, or a tire bell. There are many types of wheels according to diameter, width, molding method, and material. Aluminum alloy wheels need to be positioned during the processing to ensure that they match the working trajectory of the processing parts. At the same time, the wheel hub needs to be effectively clamped during the positioning process, and the force range must be controlled within a range that will not cause damage to the wheel hub surface.

[0003] The positioning chuck in the prior art has a complex structure and is relatively bulky, and is not flexible enough to use. In addition, in actual production, some wheel hub blanks are often affected by factors such as casting burrs and heat treatment deformation, resulting in the outer edge of the wheel hub blank not being a standard perfect circle. Therefore, the method of using a transverse pull rod to drive the stepped positioning block to slide left and right to complete the radial positioning of the wheel hub blank cannot meet the positioning accuracy requirements of the wheel hub blank installation, and the positioning will have a large deviation. Utility Model Content
