The invention discloses an ultrasonic compound finishing machine tool for removing slender rod burrs by abrasive current ultrasonic compounding. The machine tool is characterized by comprising a base (1), an abrasive barrel (2) and a slender rod single fixture (6); the slender rod single fixture (6) is clamped on the slender rod single fixture (6) through a clamping nut (5); the slender rod single fixture (6) is connected with an ultrasonic abrasive compounding special fixture (7); the ultrasonic abrasive compounding special fixture (7) is connected with an amplitude change rod (8); the amplitude change rod (8) is connected with an ultrasonic generation device (9); a stirring head of a stirring device (4) extends into the abrasive barrel (2) to guarantee that liquid abrasives in the abrasive barrel are in a suspension state; and an outlet end of a hydraulic diaphragm pump (14) communicates with the ultrasonic abrasive compounding special fixture (7) through an air damper (11). The machine tool is simple in structure, convenient to manufacture and high in machining efficiency, and realizes green machining.
Description
technical field [0001] The invention relates to an ultrasonic composite finishing machine tool, in particular to a special ultrasonic composite finishing machine tool for ultrasonic composite removal of burrs on slender rods by abrasive flow. Background technique [0002] The surface finishing of the workpiece has always been the focus of researchers. The surface quality of the workpiece determines the performance and reliability of the workpiece. Especially in aerospace, national defense and military, etc., its importance is particularly prominent, such as the deburring of valves and spools of parts that play an important role in aerospace, as well as metal thin tubes and cross holes in medical equipment. The deburring process of the inner wall of the slender rod also needs to be solved urgently. [0003] The original slender rods are removed by electrochemical deburring process, which does not conform to the concept of green manufacturing. At present, manual deburring is ...
