Ultrasonic magnetorheological vibration drilling device

An ultrasonic magnetorheological vibration drilling device comprises a lathe bed, a base, a working table, a spindle system and a cutter and is characterized in that the spindle system is connected with an energy converter, an output end of the energy converter is connected with an input end of a cone-shaped amplitude-variable bar, an output end of the cone-shaped amplitude-variable bar is matched with the cutter in a Mohs taper shank form, an auxiliary electrode is arranged on the upper surface of the working table, a workpiece is arranged on the upper surface of the auxiliary electrode, a check ring is arranged on the upper surface of the workpiece, and magnetorheological fluid particles and abrasive particles are arranged in the round check ring. According to the device, due to the action of a magnetic field, the magnetorheological fluid particles flow to a gap between the cutter and the workpiece, cuttings caused by machining are far away from the machining surface, and the magnetorheological fluid partic
