After wave vibration control runs 2 information command of computer, cutter head frequency can be quickly captured, and in the temperature change of knife or the frequency of knife
When rate changes, automatic frequency tracking is carried out, frequency is lockked using the method that the quick scan frequency of broadband captures, it is then gradually smart
Quasi- scanning adjustment.
The present invention is acted on ultrasonic activation on cutter using ultrasonic transducer, and ultrasonic transducer is arranged in knife handle
In.But knife handle is that rotation sends out ultrasonic power so the present invention designs a set of wireless power supply in process
The electric energy that raw device 3 generates passes to the ultrasonic transducer 5 in knife handle by wireless power supply.
As shown in figure 3, the non-contact wireless power supply 4 of ultrasonic transducer of the present invention, is mainly completed by rotary transformer
Power transformation function, the device include transformer secondary output and secondary, and primary is made of primary magnetic core 41, primary coil 42, are become
Depressor secondary is made of secondary magnetic core 43, secondary coil 44, is generated electricity between primary and secondary by magnetic coupling, primary
Wire circle is different between secondary, and the voltage of output is just different.In the present invention, in order to cooperate the revolving property of knife handle, it will become
Depressor primary is fixed, by transformer secondary output in knife handle, rotates with knife handle, so producing when primary is powered
The magnetisation line of force, the transformer secondary output of rotation cut the primary magnetic line of force and generate electricity.For the self-movement for keeping knife handle, transformer
Secondary and secondary is separately positioned, between be spaced certain interval D.
Further, primary coil is solidificated in primary magnetic core by electric insulating sealant, secondary coil is close by insulating
Sealing is solidificated in secondary magnetic core.
Further, primary magnetic core 41 and secondary magnetic core 43 are all a U-type groove magnet ring, and coil is corresponding in U-type groove.
Primary is fixedly mounted on main shaft of numerical control machine tool bracket；Transformer secondary output is fixed on by electric insulating sealant
In the annular groove that knife handle surface opens up, fixed rear surface and knife handle flush make itself and knife handle become an entirety.Transformer
Two magnet ring magnetic poles of primary and secondary are opposite, D separated by a distance after fixing, and guarantee to contact when secondary and then knife handle rotation
To primary.Transformer is by the way that in cable connection to ultrasonic power generator 3, secondary coil is arrived by cable connection
On ultrasonic transducer 6, ultrasonic power generator high voltagehigh frequency electric energy is converted to magnetic field, transformer secondary output by primary
Pass through coupling transformer primary magnetic field and is converted into ultrasonic transducer work energy.
The present invention conveys ultrasonic energy in a manner of voltage conversion output, is a new mentality of designing；It is contactless
Wireless power supply system also solves the problems, such as the winding of knife handle rotary cable, so that electric energy realizes delivered spaced.
Ultrasonic transducer 5 combines the structure of knife handle 6 in knife handle 6.As shown in Figure 4,5, 6, knife handle 6 is in traditional infrastructure
On improve, firstly, as previously mentioned, annular groove is opened up in 6 outer surface of knife handle, wherein installing transformer secondary output；Secondly, knife
6 center of handle is emptied, inside inserting ultrasonic transducer 5, the ring Zhou Kaishe on the end face connecting with ultrasonic transducer 5 of knife handle 6
There is flange bolt hole, passes through bolt and 5 flanged joint of ultrasonic transducer.5 head of ultrasonic transducer is exposed, for connecting
Connect collet cutter 7.The electrode 51 of ultrasonic transducer 5, piezoelectric ceramics 52, insulator 53 etc. are mounted in the inside of knife handle, amplitude transformer
Related flange 55 on 54,54 head of amplitude transformer set external screw thread connecting clip cutter 7.Knife handle head uses standard numerical control machine tool handle
Head, such as BT series, IOS series, the knife handles head such as HSK series, fast and easy handling cutter；Knife handle collet installing mechanism is using general
Structure size design, can be compatible with ER collet, KR collet, and SK collet etc. is versatile.
Ultrasonic transducer 5 obtains electric generation high-frequency vibration, drives collet cutter 7 to vibrate together, ultrasonic transducer 5
Narrow high-frequency vibration is generated, so cutter is small to the vibration intensity of workpiece, workpiece will not be destroyed.But the if high frequency of ultrasonic wave
Effect of vibration to cutter in that on lathe, will generate shake, the problems such as generating cutter fever frequency drift, therefore damping problem is always
It is insoluble problem.In order not to allow in ultrasonic energy back transfer to main shaft of numerical control machine tool, set on ultrasonic transducer
In respect of damping.Further, the damping, which refers to, sets in energy converter flange 55 close to the root position of amplitude transformer 54
The damping groove 56 of a ring shape is counted, as shown in Figure 7, Figure 8.
Shock absorption principle is as follows:
As shown in figure 8, damping groove 56 and amplitude transformer 54 are natural sparse model transition, transition face S can be arcwall face can also
To be tapered plane, the size of the point that transition face S intersects with damping groove 56 to 56 root of damping groove is defined as D, transition face S with
The size of point to 56 root of damping groove (and amplitude transformer root) that amplitude transformer 54 intersects is defined as E, by dimensioning be D and
The triangle shadow region that two right-angle sides of E surround all can be transitional region.The point that transition face S intersects with damping groove 56,
Line (the triangle that two right-angle sides namely having a size of D and E surround between the point that intersects with amplitude transformer 54 of transition face S
The bevel edge of shape) with 54 axial angle of amplitude transformer be defined as F.It is this to pass through the knot that damping groove 56 is collapsed to amplitude transformer 54 from flange
Structure, when ultrasonic wave comes from back side radiant, energy can be focused on center and is applied on cutter by damping groove horn mouth.
Meanwhile the flange of damping groove outer ring thickeies, and forms the cliff of displacement together with Damping ditch slot, the thickening of the cliff of displacement is having a size of A
The transition face of (flange normal thickness should be a), damping groove 56 and the cliff of displacement is defined as S ', the folder of transition face S ' and amplitude transformer axial direction
Angle is adjustable between ± 60 °, such as the angle B and angle C in Fig. 8.Segment thickness other than damping groove increases and its quality becomes
Greatly, greater than the part of damping groove, will significantly decay when such ultrasonic transmission is to this cliff of displacement.
Reach damping purpose by design above two, by designing damping on the transducer, solves energy damage
It becomes estranged the problem of destroying machine tool.The each key position size of shock absorbing part, which meets following requirement, simultaneously can reach damping effect
Fruit:
A:0.5 to 3 millimeters
B:0 to 60 degree
C:0 to 60 degree
D:0 to 15 millimeters
