The specific embodiment
The utility model is fixedly connected with by fixing hole and lathe, utilizes screw-nut to assemble base, micrometric displacement compliant mechanism and piezoelectric ceramics, and the device assembling is fixed on lathe.Apply the poor sinusoidal signal of out of phase by the piezoelectric ceramics of giving three vertical direction, apply respectively following signal to x direction, y direction and z direction:
Obviously,
be respectively the amplitude of three sinusoidal signals,
be respectively the initial phase of three sinusoidal signals,
for vibration frequency, t is time variable.The sinusoidal signal of x direction drives rear side piezoelectric ceramics to move, and drives knife rest to do front-rear reciprocation movement under the guiding of four straight round flexible hinges of symmetry; The sinusoidal signal of y direction drives the piezoelectric ceramics action of two, right side, drives " mouth " shaped support frame band movable knife rack under the guiding of four symmetrical twin shaft rectangle type flexible hinges, to do left and right and moves back and forth; The sinusoidal signal of z direction drives bottom side piezoelectric ceramics action, drives " mouth " shaped support frame band movable knife rack to pump under the guiding of four symmetrical twin shaft rectangle type flexible hinges.Follow phase place extent by the amplitude size of controlling the sinusoidal signal applying, can synthesize between two the different elliptical trajectories in xy, xz, tri-planes of yz, by the elliptical trajectory obtaining in basic plane and superimposed different elliptical trajectories that just can obtain space of sinusoidal signal perpendicular to this face.Because right side and bottom side are all to be driven by two piezoelectric ceramic actuators, so easily obtain the vibration of larger frequency, between L shaped pretension plate and " mouth " shaped support frame, be connected by four symmetrical vertical twin shaft rectangle type flexible hinges simultaneously, between " mouth " shaped support frame and knife rest, be connected by four symmetrical straight round flexible hinges, in driving process, symmetrical flexible hinge has well been divided equally driving force like this, make motion more steadily accurately, also extended accordingly service life of the present utility model simultaneously.
Meanwhile, can input by active accommodation three sinusoidal signals of piezoelectric ceramics
amplitude
size, frequency f and phase place
variation adjust shape and the position of space ellipse, the relevant parameters of inputting sinusoidal signal by adjustment reaches the object from the three-dimensional elliptical trajectory of main control, can better adapt to like this processing operation under different machining conditions.
The utility model can be arranged on accurate and super precision lathe and apply, and can the utility model be bonded on precision or super precision lathe by being fixedly connected with of screw bolt and nut, for example, can be fixed on the slip crate of lathe and carry out work.Due to of the present utility model simple in structure, be easy to assembling, can well coordinate with accurate and super precision lathe the task of precision cutting, compared with traditional machining, under of the present utility model assisting, can obtain a series of advantage, as reduce cutting force, heat in metal cutting, extend cutter life etc.
