Definitions

Ultrasonic processing devices usually consist of e.g. piezoelectric vibration exciter, a coaxial sonotrode and a coaxial tool.
the sonotrode is a rotationally symmetrical body and acts as a spring-mass system.
the vibration exciter excites them to longitudinal natural vibrations, which form around a node level.
the sonotrode often has a larger cross section on the input side than on the output side. As a result, it acts as an amplitude amplifier.
the known ultrasonic devices build relatively long in the direction of the oscillation axis, so that workpieces that are difficult to access are often difficult to machine.
the present invention has for its object to provide a sonotrode that allows a shorter length in the direction of vibration of the tool. This object is achieved by the combination of features of the claims.
the vibration exciter 1 consists of a vibration exciter 1 with a piezo-quartz thickness transducer 2 and two metal cylinders 3 connected at the end, an amplifier or booster 4, a sonotrode 5 and a tool 6.
the vibration exciter is cylindrical and has longitudinal longitudinal harmonic vibrations its axis 10 with a node plane in its axial longitudinal center. The maximum amplitude occurs on the end faces of the vibration exciter 1.
the thicker end face of the coaxial amplifier 4 designed as a rotating body is connected to one end face.
the amplifier 4 is preferably tapered towards the other end face and also oscillates longitudinally about a node plane at its natural frequency. The vibration amplitude is increased by the taper.
the sonotrode 5 is designed as an annular bending oscillator with a cylindrical outer surface 15 and a coaxial, cylindrical inner surface 16.
the thinner end of the amplifier 4 is screwed into an inlet 17 of the sonotrode, which is designed as an internal thread.
the inlet 17 is coaxial to the axis 10 and radially to the cylindrical outer surface 15.
the outlet 18 of the sonotrode 5 is designed as a bore into which the tubular tool 6 is firmly connected (e.g. soldered).
the output axis 19 is also radial and intersects the input axis 10 at an angle of approximately 90 °.
a coaxial tube 20 is formed on the sonotrode 4 and communicates with a bore 21 passing through the vibration exciter 1 and the amplifier 4.
the tube 20 is connected to the axial bore 23 of the tool 6 via a hose 22.
abrasive can be sucked out of the end face 24 of the tool 6, which acts as a working surface, or can be supplied to this end face 24 through the bore 21, the hose 22 and the hollow tool 6.
the natural bending frequency of the sonotrode 5 is equal to the longitudinal natural vibration frequency of the amplifier 4 and the vibration exciter 1.
the sonotrode 5 oscillates around four nodes 33 to 36.
FIG. 2 shows the oscillation of the neutral fiber of the sonotrode 5. If the cross section of the sonotrode 5 is the same over the entire circumference, the output amplitude 31 of the sonotrode oscillation is equal to the input amplitude 30 (apart from friction losses). As can be seen, the output amplitude is maximum when the output axis 19 is perpendicular to the input axis 10, but the output amplitude is still close to the maximum value when the angle is slight, e.g. Deviates from this value by ⁇ 20 °.
the ring cross section of the sonotrode 5 increases from the exit 18 on both sides to the diametrically opposite point.
An advantageous embodiment of this variant is shown in FIG. 3:
the sonotrode 5 is wedge-shaped when projected in the direction of the input axis 10. As a result, the sonotrode 5 acts as an amplifier and the output amplitude 31 is greater than the input amplitude 30.
FIG. 4 shows a variant of the sonotrode 5, in which the tool 6 is detachably connected to the sonotrode, e.g. screwed into a nut thread 18 'from above.
an abrasive supply can additionally be provided via an additional bore 40 in the amplifier 4, a further hose 41 and an annular nozzle 42 surrounding the tool 6.
the inventive design of the sonotrode 5 as an annular bending oscillator ensures that the tool 6 oscillates at an angle to the axis 10 of the vibration exciter 1 and amplifier 4. This allows workpieces that are difficult to access to be processed efficiently using ultrasound.
the tool 6 is to vibrate laterally in addition to the longitudinal vibrations, it can be angled.
