[0002] The production of bicycle wheels requires the assembly of the rim (which can be a disc wheel or a cutter wheel) and the hub assembly. The process steps of a carbon fiber bicycle disc wheel or cutter wheel product are as follows: first, the carbon fiber disc wheel and cutter wheel body products (including the bonding surface and size structure, etc.) are formed and produced, and the flatness indicators of the carbon fiber disc wheel and cutter wheel body are confirmed to be good products, and then the trimming operation is carried out, and then the grinding and spraying operation (grinding and repairing the carbon fiber surface) is carried out. After the grinding and repairing, the carbon fiber disc wheel and cutter wheel are glued to the hub assembly.
[0003] The wheel rim hub bonding adjustment device of the prior art has a problem that the rim and the inner shaft of the hub are not effectively fixed and limited. Therefore, when the adjustment rotation is performed, the inner shaft of the hub is prone to slip or even completely slide out of the supporting ear frame. This not only affects the adjustment work, but is also likely to lead to a reduction in the adjustment accuracy, and even cause equipment damage and safety risks to the staff. The design without fixed limits makes the adjustment operation unstable and unreliable. During the rotation process, the instability of the inner shaft of the hub will directly affect the accuracy of the adjustment result, making it difficult for the adjustment work to achieve the expected effect.
