Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub calibration, in particular to a manual calibration device applied to a wheel hub drilling fixture. Background Art

[0002] The wheel hub is the rotating part of the wheel core, connected to the tire's inner profile by a column. It's the central metal component that supports the tire and is mounted on an axle. It's also called a rim, steel wheel, wheel, or wheel bell. Wheel hubs come in a wide variety of diameters, widths, molding methods, and materials. The tire and wheel assembly often can't be fully assembled at once, which is difficult to observe with the naked eye. Installing a tire and wheel on a car without a fully assembled tire and wheel increases safety risks and causes wear on both tires and wheels, leading to economic losses and potential safety hazards. In existing technologies, inaccurate circumferential (Z-rotation) positioning of the wheel hub leads to increased product defect rates.

[0003] In summary, how to design a manual calibration device for hub drilling fixture to solve the problem of hub circumferential (Z rotation) positioning difficulty and avoid circumferential (Z rotation) positioning error is an urgent problem to be solved by those skilled in the art.
