Device for machining flange plate half shaft

The invention discloses a device for machining a flange plate half shaft. The device comprises a spline turning device, two punching devices, two clamping devices, a bearing device, a first driving device, a second driving device, a third driving device and a fourth driving device, wherein the two punching devices are used for punching a center hole of a flange plate of the flange plate half shaftand the spline end of the flange plate of the flange plate half shaft separately; the two clamping devices are used for clamping the flange plate and the half shaft of the flange plate half shaft correspondingly; the half shaft is arranged in an inner ring of the bearing device; the first driving device drives the half shaft to rotate; the second driving device drives the punching devices to makeaxial movement; the third driving device drives the spline turning device to be away from or get close to the half shaft; and the fourth driving device drives the clamping devices to be clamped and loosened.
