The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises piezoelectric ceramics group 4, horn 6, duralumin piece 3 and directive wheel 8; Directive wheel 8 centers have the big and little shoulder hole of mid diameter of two ends diameter; After horn 6 one ends pass directive wheel 8 central small hole; Be fixed on the one end aperture end face of directive wheel 8 centers with locking nut 7; The large conic end of horn 6 other ends withstands on the end face of directive wheel 8 center other end apertures; After in rotating shaft connection support 5 holes on the small cone end of horn 6 other ends piezoelectric ceramics group 4 and duralumin piece 3 outwards being installed successively, be fixedly connected with bolt 2, rotating shaft connects support 5 and is connected with motor through power transmission shaft; Have many cannelures that are equally spaced vertically at directive wheel 8 external cylindrical surfaces.
Described cannelure bar number is to set according to the processing request that is cut material.
Like Fig. 4 and shown in Figure 5, during use, follower 9 external cylindrical surfaces also have with directive wheel 8 along axle and equate the cannelure that the bar number is equally spaced, and incisory steel wire 1 is installed respectively in every cannelure, and directive wheel 8 rotates after many steel wires 1 drive follower 9 rotations.
Alternate electrical signal makes piezoelectric ceramics group 4 produce mechanical oscillation through after the piezoelectric ceramics group 4, and mechanical oscillation act on the horn 6; Make horn 6 produce axial vibration; To produce compressional wave vertically in the horn 6, the particle vibration direction of displacement is parallel to axially, according to elastically-deformable poisson effect; Axial distortion can cause horizontal deformation, so particle also produces displacement perpendicular to axial direction when producing axial displacement.Make directive wheel 8 produce radial vibrations after horn 6 and directive wheel 8 cascades.Directive wheel 8 can connect support 5 through rotating shaft to be realized being connected with electric machine rotational axis, drives directive wheel 8 rotations.
In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, further specify the technical scheme and the course of work of the utility model.
The rotary ultrasonic transducer is used in the cutting of multifibres line, comprising: duralumin piece 3, piezoelectric ceramics group 4, horn 6 and directive wheel 8.It is fixing through bolt 2 that piezoelectric ceramics group 4 is clamped the back by duralumin piece 3 and horn 6, and horn 6 axially has internal thread hole, is used for fixing bolt 2; Horn 6 is passed directive wheel 8 vertically; Have circular hole in the middle of the directive wheel 8, through locking nut 7 horn 6 is fixed on the directive wheel 8, the end of horn 6 has external screw thread; Be used for the fixing of locking nut 7, it is as a whole with horn 6 that rotating shaft connects support 5.Above type of attachment all belongs to mechanical connection, and the constant intensity that is produced by mechanical connection is enough, thus the displacement that can not cause owing to external vibration in use or come off.On piezoelectric ceramics group 4, load the excitation alternating voltage through collecting ring, make piezoelectric ceramics group 4 produce mechanical oscillation, produce extensional vibration thereby drive horn 6, the vibration of horn 6 is delivered to the directive wheel 8 that is attached thereto, and makes directive wheel produce radial vibration.Difference according to the processing technology demand; Can change the radially amplitude of directive wheel 8 through setting to horn 6 sizes; Because the horn 6 that the utility model adopted is non-rule, adopt difficulty of traditional analytic method design, therefore can adopt FInite Element to carry out analytical calculation.
