Adopt technique scheme, have following beneficial effect:
Circumference is rotated on the middle supporting plate that positioning boss is fixed on machine tool, workpiece be installed on chuck and top between, with the rotation according to workpiece, the ultrasonic whirlwind of driven by motor mills main shaft device to carry out ultrasonic whirlwind to workpiece and mills and carry out the high speed and precision cutting operation.Ultrasonic machining is a kind of processing method that makes workpiece produce certain controlled vibration clocklike.Ultrasonic machining is the micro cutting process of finishing in the short time at a utmost point, surface damage and residual stress are all less, and do not rely on the electric conductivity of workpiece, and are non-electric machining processes, not influenced by electricity, the chemical characteristic of workpiece, the especially suitable hard crisp processing that waits difficult-to-machine material.
By adjusting the fixed position of set bolt in the arc adjustment hole, can adjust the cutting angle between the axis of rotation that ultrasonic whirlwind mills the rotation of main shaft device and workpiece, be convenient to process workpiece dissimilar, different size.
During ultrasonic Milling Process, the driven by motor main shaft rotates, main shaft drives profile milling cutter by the luffing bar and rotates at a high speed, the high-frequency electrical concussion that supersonic generator produces is passed to ultrasonic transducer by brush terminal box and brush, the high-frequency electrical vibration is converted to the high frequency mechanical oscillation by ultrasonic transducer, amplification by the luffing bar is amplified to the processing request that satisfies profile milling cutter with the amplitude of high frequency mechanical oscillation again, thereby makes cutter produce dither.So just under the situation that does not change lathe driving-chain structure, realize the processing of large-scale precision screw thread.
The present invention is easy to adjust, flexible, surface accuracy is high, stock-removing efficiency is high, can realize that one-pass finishes the screw thread processing of better quality, can remedy the deficiency of common cold machining processing, working (machining) efficiency is 3～5 times of common process methods, be particularly useful for the hard crisp processing that waits difficult-to-machine material, significantly improve the crudy of screw thread, practical, be easy to apply.
