Detection auxiliary device for wheel hub

The invention discloses a detection auxiliary device for a wheel hub. The device includes a fixation mechanism, a driving mechanism and a transmission mechanism. The fixation mechanism includes a clamping unit, and the clamping unit is used for fixing the wheel hub; the driving mechanism includes a rotating unit and a clamping driving unit, the rotating unit drives the fixing mechanism to rotate around the center of the wheel hub, and the clamping driving unit drives the clamping unit to move; the transmission mechanism is connected to the rotating unit and the fixation mechanism, and transmits torque of the rotating unit to the fixation mechanism; and the transmission mechanism is also connected to the clamping driving unit and the clamping unit, and is driven by the clamping drive unit to clamp or loosen the wheel hub. The fixation mechanism achieves rotation and clamping functions through simultaneous connection of the rotating unit and the clamping driving unit through the integrated transmission mechanis
