Abstract
The utility model relates to a large power supersonic vibrator, relating to an industrial supersonic generating device, comprising one vibrating head and one composite stick which is made by a central screw in series connecting with one front cover, a vibrating chip and a back cover. The large power supersonic vibrator is characterized in that the front cover and the back cover are both made of two different metals. The acoustic impedance rate of the front cover and the back cover matches with the acoustic impedance rate of the vibrating chip. Optimum sound conversion efficiency is obtained. The back cover can not burn out the vibrating chip because of burning. Thus, the utility model is used for supersonic cleaning vibrator to obtain very high cleaning effect. The large power supersonic vibrator has the advantages of long service life and stable performance.
Description
The utility model relates to a kind of industrial ultrasonic generator tool.
The large power supersonic oscillator that the existing eighties is general.The general piezoelectric ceramic piece that adopts, protecgulum and bonnet with metal, constitute its compound bar by center bolt serial connection, compound bar is fixed in the casing, refill shake the head and form, the acoustic wave energy that piezoelectric ceramic piece vibration is produced is sent to by metal bezel and shakes head and transfer out, but, often because before, the metal material that bonnet is selected, the specific acoustic impedance of its specific acoustic impedance and piezoelectric ceramic piece does not match, when causing acoustic energy in compound bar, to transmit, energy loss is bigger, makes bonnet hot, even burns out piezoelectric ceramic piece, and cause this kind oscillator service life short, and deadly defect such as efficient is lower.
The purpose of this utility model is: the protecgulum that a kind of its serial connection closes system and the specific acoustic impedance and the piezoelectric ceramic piece specific acoustic impedance coupling of bonnet are provided, make the higher and durable large power supersonic ticker of conversion efficiency.
Technical essential of the present utility model is: the protecgulum of ticker, the different metal material piece serial connection that bonnet adopts two or more (comprising two kinds) are made, its geometric average specific acoustic impedance and piezoelectric ceramic piece specific acoustic impedance are complementary, be stamped first protecgulum before promptly establishing, second protecgulum: bonnet also has first bonnet and second bonnet, its first, second represent to adopt two kinds of different metal materials respectively, protecgulum, bonnet all are serially connected with the vibration wafer two ends of center bolt.
Simultaneously, take necessary glissando,, increase durable tolerance to reduce the influence of hull vibration.
Detailed structure of the present utility model gives detailed description by the embodiment accompanying drawing that provides:
Fig. 1 is the utility model structural representation.
Among the figure: the 1--head that shakes, 2--is nodal section fixedly, 3--first protecgulum
Four piezoelectric ceramic pieces of the 4--second protecgulum 5--center bolt 6--
7--flame-retarded foamed plastic 8--electrode slice 9--second bonnet
The 10--first bonnet 11--casing
Wherein, first protecgulum adopts identical metal carbon steel material to make with first bonnet, and second protecgulum adopts identical aluminum alloy materials to make with second bonnet, and their specific acoustic impedance is respectively: p
1C
1=39.78 * 10
6Kg/m
2S, p
2C
2=14.04 * 10
6Kg/m
2S, both geometrical means are
Like this, just in time with the specific acoustic impedance P of piezoelectric ceramic piece
0C
0=22.42 * 10
6Kg/m
2S is close.So, the protecgulum and first bonnet that adopt first protecgulum to be connected in series with second protecgulum to make are connected in series the bonnet made from second bonnet, just adopt two kinds of different materials, as: protecgulum and bonnet that carbon steel and aluminum alloy materials piece serial connection are made, be serially connected with the vibration wafer two ends of center bolt, can be so that the specific acoustic impedance of the specific acoustic impedance of forward and backward lid and piezoelectric ceramic piece be complementary, thereby, make the unlikely back wave that in compound bar, produces of sound oscillation energy, cause the loss of acoustic energy.And obtain higher sound conversion ratio.Two kinds of different materials of indication can also be titanium alloy and aluminium alloy.
Simultaneously; in order to reduce the energy loss that various extraneous vibration brings; also taked some necessary glissandoes: as: 1. all have the beam of making by vegetable cork or foamed plastics elastomeric material at fixedly nodal section 2 places that ticker is fixed in casing: 2. the electrode slice 8 bonding wires part of piezoelectric ceramic piece being drawn is all curved turn 90 degrees after; and second bonnet between the thick flame-retarded foamed plastic 7 of cushioning; because the specific acoustic impedance of foamed plastics is significantly less than the piezoelectric ceramic piece specific acoustic impedance; so can decay by the caused vibration of electrode slice; thereby; the guard electrode sheet is difficult for impaired, and eliminates the added losses that vibration is thus produced.
The utility model has the advantage of: 1. before having solved in the large power supersonic ticker, The specific acoustic impedance matching problem of bonnet and piezoelectric ceramic piece. Overcome because sound energy loss is big Cause the deadly defects such as bonnet is hot, piezoelectric ceramic piece easy burn-out, thereby obtained well The acoustic energy conversion efficiency. Make and the utlity model has long service life, advantage that efficient is high; 2. Owing to adopted some necessary glissandoes; Eliminated additional energy loss, and protection Electrode slice is difficult for impaired, makes this ticker stable performance, and is good, use at supersonic cleaning machine On have higher cleaning performance.
