Vertical type wheel hub dynamic balancing machine

The invention discloses a vertical type wheel hub dynamic balancing machine, comprising a frame and a control mechanism, a main shaft for supporting the wheel hub and drive the wheel hub to rotate is arranged vertically on the frame, the main shaft is driven by a motor, a jacket driven by a cylinder for clamping the wheel hub is arranged at the top, the bottom of the main shaft is connected with a horizontal stress plate, a vertical force sensor and a horizontal force sensor for respectively measuring the vertical weight and the horizontal weight of the wheel hub are arranged near the stress plate, the control mechanism is used for receiving the measuring value of the vertical force sensor and the horizontal force sensor, the size and the phase of the dynamic imbalance amount of the upper end surface and the lower end surface are calculated according to the formula (I). The dynamic balancing machine adopts the vertical type dynamic balancing machine structure, the sensor can not support the weight of the maqc
