Description
(1) technical field
The present invention relates to a kind of vibration boring method and device, particularly relate to a kind of leading type auto-feed Boring by Cutter under Ultrasonic Vibration method and the device that are used for drilling, belong to metal cutting processing and metal cutting equipment component technology field.
(2) background technology
Under the prior art condition, the hole processes the especially little macropore processing in operating space, and there are problems such as processing dynamics deficiency, process system poor rigidity in conventional processing, and cutting effect is undesirable.Because the bottom outlet surplus is uneven, conventional boring process cutting force is big, and the process system deformation that knife bar, lathe bed, workpiece constitute is big, and " error is rerun a movie " is serious, is difficult to realize accurate correction.Boring by Cutter under Ultrasonic Vibration has extremely strong precision cutting ability, and actual cutting-in very near theoretical cutting-in, significantly improves the bore hole surface quality, reaches ground effect; Ultrasonic boring cutting force is impulse type, and amplitude is less than common cutting force, and the corresponding mean force of actual machine is the counteracting of positive negative pulse stuffing less than common cutting force, particularly radial-thrust force more, makes average drag be merely one of the percentage magnitude of common cutting; Ultrasonic boring processing is significantly eliminated " error is rerun a movie " phenomenon, improves the linearity of bore hole, reaches rectifying effect.
Existing Boring by Cutter under Ultrasonic Vibration adopts boring bar one end to fix, and the boring method that overhangs that the other end is unsettled constantly overhangs because boring bar is sent to main shaft, and the amount of deflection that the knife bar system produces because of deadweight changes is also different, and when the longer endoporus of processing, the axis in hole is prone to produce crooked.Because main shaft constantly stretches out, the continuous variation of whole knife bar system rigidity, under the cutting force effect, the system resilience distortion increases gradually, influences the boring precision in hole during boring, makes processed hole produce deviation from cylindrical form.Adopt leading type ultrasonic vibration bore hole, can significantly improve the process system rigidity, surface quality reaches ground effect behind the bore hole, and dimensional accuracy, axiality and linearity are significantly improved.
The ultrasonic vibration transducer is a most important component in the ultrasonic vibration system of processing, and its design effect directly influences the quality of processing.Generally speaking, transducer self has three kinds of vibration modes: extensional vibration, flexural vibrations and twisting vibration can obtain elliptical vibration after two kinds of vibration modes are compound with certain phase difference.Two curved oval transducers can vibrate the compound elliptical vibration that obtains through the tangent bend that two driving sources provide respectively; And can also obtain multiple multi-form elliptical vibration through driving voltage size and the phase difference of adjusting two driving sources, this is very useful beyond doubt to the influence of crudy for the different vibration mode of research.
