5, amplitude transformer 6, tool heads etc. mix the compositions such as connecting screw and lead, outside protective covers again（Such as Fig. 1）.
It is an important technique that how preceding load block 5 and amplitude transformer 6 are clamped in transducer system.Be clamped it is bad will
The transfer efficiency of energy converter and the stability of welding are seriously affected, the quality of weldment is directly affected.Therefore load block 5 before energy converter
Can the clamping with amplitude transformer 6 becomes Ultrasonic machining stablize one key of progress.The piezoelectric element of energy converter accesses high-frequency electrical
Piezoelectric effect occurs after pressure, tens of thousands of high frequency elastic vibration per second is generated, with the premenstrual load block 5 of the state of sine wave, luffing
The vibration that bar 6,8 output amplitude of soldering tip reach 5~20 μm is sent to welding zone.Each component of energy converter is bolted into using screw rod
It is whole, and on machine.Generally for being arranged and fixed conveniently, we must be simultaneously the zero of preceding load block 5 and amplitude transformer 6
A whole fixed bit of one bulge loop of processing as energy converter at shaking, achieves to be easily installed and is fixed on the machine（See Fig. 1）.By
In inconsistent or processing technology the deviation of material property, the zero of preceding load block 5 and amplitude transformer 6, which shakes, a little will appear deviation and in work
As when generate slight vibration.Whole efficiency is reduced when the vibration generation consumption that can make energy converter after reinforcing is clamped, is clamped
Position also generates heat because of vibration and is unfavorable for the normal work of machine.Existing clamp structure is usually in preceding load block 5 and luffing
The vehicle that shakes of the zero of bar 6 goes out a bulge loop, with certain gap and mixes using upper and lower gasket 11,12 and mutually clamp ring 13, lower clamping 14
Form is gripping position transmission to eliminate vibration, and whole complex so as to cause energy converter 1, part is more.And its
When processing installation fee, and volume is larger, and adaptability and consistency are poor, and vibration can not preferably be overcome to generate the feelings of fever
Condition.
Utility model content
The purpose of the utility model is to overcome existing ultrasonic transducer clamping bulge loop it is complicated, part compared with
More, processing time-consuming, the deficiencies of vibration cannot be overcome to generate heat well difficult to install, and provide a kind of simple in structure, installation be easy,
The improvement ultrasonic transducer that vibration can be overcome to generate heat well.
What the purpose of this utility model was realized in：

The front end face that bulge loop is clamped is equipped with the first weakening annular groove, the first weakening annular groove and the along the circumferential direction of clamping bulge loop
It is staggered inside and outside two weakening annular grooves.
The utility model can also improve further below.
The preceding load block is integrally formed with clamping bulge loop.
The rear end face of the clamping bulge loop is equipped with a plurality of spaced second vibration absorbing ring along the circumferential direction of clamping bulge loop
The front end face of shape slot, the clamping bulge loop is equipped with a plurality of spaced first weakening annular along the circumferential direction of clamping bulge loop
Slot.
The transducer body is connected successively back to front by rear connection bolt, back loading block, electrode copper sheet, piezoelectric ceramics
Composition is connect, the another side of the piezoelectric ceramics is connect with the rear end of preceding load block, and the front end of preceding load block is connect with soldering tip.
The depth of the first weakening annular groove is consistent with the depth of the second weakening annular groove.
The depth of the first weakening annular groove is the 3/4 of the thickness that bulge loop is clamped.
The beneficial effects of the utility model are as follows：
（One）The clamping bulge loop of the utility model is integrally formed with preceding load block, therefore avoids the inconsistent of material property
Or the deviation of processing technology, and bulge loop is clamped and is connected by the way of being threadedly coupled, it shakes to solve the zero of preceding load block
Point will appear deviation and lead to the problem of slight vibration at work.The structure of the utility model ultrasonic transducer is simple,
The deficiencies of processing is easy, installation is easy, vibration can be overcome to generate heat well can overcome the problems, such as vibration fever well.
（Two）In addition, the clamping bulge loop of the utility model is equipped with the first weakening annular groove, the second weakening annular groove, therefore
With resilient property welding equipment production will not be corresponded to ensure sound wave conscientiously while in longitudinally to soldering tip transmittance process
Raw oscillation crosswise.
