Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, in particular to a wheel hub positioning fixture. Background Art

[0002] A wheel hub is a metal component mounted on a vehicle like a car or truck to support and secure the tire. It's typically made of metal, such as aluminum alloy, steel, or magnesium alloy, for its strength and durability. While its primary function is to support the tire, it also influences the size of the brake pedal and tire. There are many different types of wheels, depending on their diameter, width, molding method, and material.

[0003] Patent No. 201920420787.5 discloses a wheel hub tooling positioning fixture. The device avoids damage to the wheel hub caused by high force during the positioning process through soft contact between the airbag and the wheel hub. It can be used to position wheels made of softer aluminum alloy, and the clamping and disassembly processes are relatively convenient.

[0004] However, when the existing hub tooling positioning fixture is used, the hub is processed using the positioning fixture to avoid deviation during hub processing. However, the hub processing position is not fixed, and the position of the hub cannot be effectively adjusted. The staff needs to adjust their position to achieve processing at different positions of the hub. The operation steps are cumbersome and have a certain impact on the processing efficiency of the hub. Therefore, a hub positioning fixture is provided. Utility Model Content
