Double-plate type six-dimensional force torque sensor

The invention discloses a double-plate type six-dimensional force torque sensor, and relates to the field of sensors. The sensor comprises a first strain part and a second strain part. The first strain part comprises a loading disc, a first cover pressing ring, a supporting plate and a first disc type elastic body. The second strain part comprises a second cover pressing ring, a second disc type elastic body and a fixed base. The basic structure also comprises a semiconductor strain assembly, a circuit board and a fixed connecting piece. The first disc type elastic body is fixed on a bracket through a first cover pressing ring, and the bracket is fixed below the loading circular plate. The second disc type elastic body is fixed on the fixed base through a second cover pressing ring. The two stages of strain parts are connected through a boss at the central position of the disc-type elastic body. The first disc type elastic body and the second disc type elastic body are respectively provided with six groups of
