The invention relates to a double-spiral-groove combined type single-excitation three-dimensional curved surface ultrasonic-assisted turning device and belongs to the field of compound ultrasonic vibration cutting machining. The double-spiral-groove combined type single-excitation three-dimensional curved surface ultrasonic-assisted turning device comprises an ultrasonic excitation device, a double-spiral-groove combined type pressing twisting device and a fixed frame. Through combination of the ultrasonic excitation device and the double-spiral-groove combined pressing twisting device, underultrasonic high-frequency vibration excitation, the double-spiral-groove combined type pressing twisting device is twisted in the horizontal direction and meanwhile deforms in the vertical direction,a turning tool vibrates up and down to a certain extent in the vertical plane in the axial direction while being driven to make arc-shaped rotation movement in the horizontal plane, and one-dimensional ultrasonic vibration gen
