Description

Technical Field

[0001] The present invention relates to the technical field of automobile axle wheel processing, in particular to a processing system and a processing method for automobile axle wheels. Background Art

[0002] An automotive axle is the transmission device connecting the vehicle's drive system to the wheels. It typically includes one or two half-shafts (depending on the vehicle's drivetrain) and is used to efficiently transmit engine torque to the wheels. One end of the axle is connected to the differential or drive shaft, while the other end is connected to the wheel rim via a ball joint. This structural design allows the wheel to rotate around a fixed point (usually the steering knuckle), enabling the vehicle to move and travel.

[0003] For example, Chinese patent CN115091281A discloses a system and method for machining the small inner ring of an automotive wheel hub bearing, which relates to the technical field of metal processing. The system comprises a lifting and rotating mechanism, a measuring assembly, and a small inner ring grinder. The sidewall of the inner flange ring is provided with a press-fit surface. The measuring assembly comprises a standard small inner ring, a measuring sleeve, and an inductor pen, which is communicatively connected to the small inner ring grinder. The lifting and rotating mechanism ascends and rotates, causing the groove of the standard small inner ring to contact a steel ball and the lower end of the measuring sleeve to press-fit the surface. The inductor pen measures the displacement of the measuring sleeve and transmits it to the small inner ring grinder, which then processes the end face of the small inner ring. Conventional automotive axles require multiple heating and cooling cycles to improve their quality and strength. However, this process consumes a lot of energy, is complex, and takes a long time, significantly impacting the efficiency of automotive axle machining. Therefore, a system and method for machining automotive axles are proposed to address these issues. Summary of the Invention
