The invention discloses an ultrasonic combined adaptive anti-fatigue precision
machining system and method of a multi-curvature curved surface, and belongs to the field of mechanical precision
machining common technologies. The ultrasonic combined adaptive anti-fatigue precision
machining system and method of the multi-curvature curved surface aim to solve the technical problem of how to
machine acurved surface of a key part with the multi-curvature curved surface while guaranteeing that the part has the anti-fatigue performance of a part with the multi-curvature curved surface. According tothe adopted technical scheme, the ultrasonic combined adaptive anti-fatigue precision
machining system structurally comprises a flexible
grinding head device and a
control unit. The
control unit is electrically connected with and has control over the flexible
grinding head device, an ultrasonic
coupling agent circulation structure and an
impact vibration structure. The flexible
grinding head device is used for machining the multi-curvature curved surface of the part. The
control unit is used for having control over the working state of the flexible grinding head device. The flexible grinding head device comprises a flexible adjustment box body, the ultrasonic
coupling agent circulation structure and the
impact vibration structure. The
impact vibration structure is arranged in the flexibleadjustment box body. The interior of the flexible adjustment box body communicates with the ultrasonic
coupling agent circulation structure. The invention further discloses the ultrasonic combined adaptive anti-fatigue precision machining method of the multi-curvature curved surface.
