The invention discloses a variable displacement type magnetic fluid variable damping rotary joint which comprises a stator magnetic conductive sheet module and a rotor magnetic conductive sheet module, the stator magnetic conductive sheet module comprises a plurality of stator magnetic conductive sheets placed in a magnetic fluid cavity shell, the stator magnetic conductive sheets are arranged in the axial direction, stator magnetic conductive sheet isolation blocks exist between the stator magnetic conductive sheets, and the rotor magnetic conductive sheet module is arranged between the stator magnetic conductive sheets. The magnetic conductive sheet isolation blocks are arranged on the surfaces of the stator magnetic conductive sheets, so that gaps exist between the stator magnetic conductive sheets; and the rotor magnetic conductive sheet module comprises a plurality of rotor magnetic conductive sheets sleeved on the guide grooves of the rotor hollow shaft, the rotor magnetic conductive sheets are arranged along the axial direction, rotor magnetic conductive sheet isolation blocks exist among the rotor magnetic conductive sheets, and the rotor magnetic conductive sheet isolation blocks are arranged on the rotor magnetic conductive sheets, so that gaps exist among the rotor magnetic conductive sheets. The high-strength permanent magnet is adopted to generate a magnetic field, and the small motor is controlled to adjust the position of the permanent magnet in the joint cavity, so that the form of the magnetic fluid in the joint is changed, and the joint damping is adjusted.
