Definitions
- the present invention relates to a large-capacity ultrasonic composite vibration device used for an ultrasonic processing machine for performing vibration processing (joining, cutting, polishing, plastic processing, and the like) on metal, plastics, ceramics, electronic components, and the like, a moving device, and the like.
- An object of the present invention is to provide a large-capacity ultrasonic composite vibration device by installing a plurality of sets of ultrasonic vibrators on a disk vibrator having high rigidity of a vibrating material and low vibration loss. It is here. Disclosure of the invention
- the present invention provides a plurality of sets of ultrasonic vibrators, which are opposed to each other and are driven in opposite phases, at equal intervals on an outer peripheral portion of the disk vibrator, so that the center of the disk vibrator is provided. This was done by finding that the part induces a composite vibration that draws a Lissajous trajectory.
- n sets (n ⁇ 2) of ported Langevin type ultrasonic transducers (hereinafter abbreviated as BLT) having the same characteristics are opposed to the outer peripheral part of a disk vibrator in which a central part forms a vibration loop.
- BLTs are driven in opposite-phase mode, and the phase between adjacent BLTs in each set is driven in a vibration mode that shifts by ⁇ / n.
- This is a large-capacity ultrasonic composite vibration device with a structure in which the center of the disk vibrator is subjected to composite vibration.
- the invention according to claim 2 has a structure in which, in the invention according to claim 1, the antinode of vibration of a vibrating round bar vibrating in a composite bending vibration mode is connected to a center portion of the disk vibrator. It is a thing.
- the disk vibrator mechanically coupled to the BLT is excited in the diameter direction connecting the axes of both BLTs.
- the ⁇ / ⁇ phase is delayed from the first set of BLTs to excite the second set of BLTs next to the first set, and the ⁇ / ⁇ phase is delayed from the second set to the third set of BLTs next to the second set. Exclude the BLT of the set and similarly excite the BLT up to the ⁇ th set.

- the center of the disk vibrator 4 is a vector sum due to the vibrations of the three sets of B L ⁇ ⁇ ⁇ , and induces a composite vibration that draws a loci trajectory.
- the vibrating round bar 5 is excited by the composite vibration induced in the disk vibrating body 4, and the vibration mode at the tip thereof becomes the elliptical vibration shown in FIG.
- the elliptical oscillation trajectory is generated by a slight difference between the drive voltage and the resonance frequency of each BL ⁇ , and is adjusted by adjusting each drive voltage and drive phase of the power amplifier with a phase shifter to form a circle. You can do it.
- the material of the disk vibrator 4 is steel S45C (diameter 126mm, thickness 40mm), the longitudinal resonance frequency of each BLT is 27kHz (diameter 40mm), and the material of the vibrating round bar 5 is steel S45C.

Is applied. This signal is applied to each pair of BLs as two signals in opposite phase mode by the transformers 7, 8, and 9 with intermediate taps.
- B L ⁇ ⁇ converts the signal into mechanical elastic vibration and drives the disk vibrator 4.
- the center of the moving object is connected to the antinode of the oscillating body to induce a compound vibration, and the vibration output is about twice that of a simple substance.
- the vibration circle 5 connected to the center of the disk body 4 is excited by the composite vibration at the center of the disk body, and its tip becomes a composite vibration, and the output is six times that of the BLT alone, and a large-capacity ultrasonic composite A vibration device can be realized.
- the embodiment of the present invention has been described in detail with reference to the drawings.
- the specific configuration of the present invention is not limited to this embodiment, and a design change without departing from the gist of the present invention.
