Abstract
The utility model relates to a vibrator in ultrasonic cleaning machine, which is designed for improving energy exchanging efficiency and reducing internal resistance. The utility model comprises a sound head and a back cover. A piezoelectric ceramic sheet and a pole sheet are arranged between the sound head and the back cover. The utility model is characterized in that: the sound head has a wimble table-shaped main body whose one end with big diameter is connected with a short cylinder and the end with small diameter is provided with a screw; the corresponding back cover is a cylinder with a through hole at the top; the sound head, the piezoelectric ceramic sheet, the pole sheet and the back cover are connected through a screw. The utility model has the advantages of simple structure, high efficiency of energy exchanging and small internal resistance, being suitable for the promotion and utilization in ultrasonic cleaning machine.
Description
The utility model relates to the critical component oscillator technical field in a kind of supersonic wave cleaning machine.
Along with science and technology is constantly progressive, wash metal parts at the industrial supersonic wave cleaning machine that used in a large number, a critical component is arranged in supersonic wave cleaning machine, it includes sound head and bonnet, be fixed with piezoelectric ceramic piece and pole piece between sound head and the bonnet, its effect is that electrical signal energy is converted into ultrasonic energy, come excited vibration liquid, play necessary cleaning function then, so say that its performance quality is very important, directly have influence on each functional parameter parameter quality of supersonic wave cleaning machine, have a lot of scientific and technical personnel that the oscillator in the supersonic wave cleaning machine is improved for this reason.In the Chinese patent literature storehouse, concentrate report supersonic wave cleaning machine technology morely, as the patent No. 94102138.6 " ultrasonic wave cleans the method for oscillating of the ultrasonic oscillator of usefulness ", the patent No. be 98226240.X's " using supersonic wave cleaning machine " more, the ultrasonic wave combined elements also there is certain report, as the patent No. is 90208268.X " a kind of combination ultrasonic transducing head ", but single oscillator structure is not had the detailed technology report, and single then oscillator performance quality is as the conversion efficiency height, dynamic internal resistance size, the simplified and traditional supersonic wave cleaning machine quality that directly has influence on of structure.
The purpose of this utility model just is to provide at above-mentioned prior art present situation the oscillator in the supersonic wave cleaning machine that a kind of conversion efficiency is higher, internal resistance is less, simple in structure.
The purpose of this utility model is achieved in that the oscillator that changes in the supersonic wave cleaning machine, it includes sound head and bonnet, piezoelectric ceramic piece and pole piece are housed between sound head and the bonnet, it is characterized in that described sound head has the taper type main body, be connected with short cylinder at the big end of its diameter, have screw at the little end center of diameter, described accordingly bonnet is a cylinder, on have through hole, with screw sound head, piezoelectric ceramic piece and pole piece, bonnet are coupled together.
Above-mentioned taper type body height 32mm, outside diameter ￠ 64mm, end diameter ￠ 38mm, it connects short cylinder height 7mm, bonnet cylinder height 22mm, diameter ￠ 38.5mm, above counter bore hole diameters ￠ 19mm, degree of depth 10mm, through-hole diameter ￠ 12.5mm, screw ￠ 12 * 1.25mm.
According to experiment, to compare with oscillator in the prior art supersonic wave cleaning machine, advantage of the present utility model is that conversion efficiency is higher, internal resistance is less, simple in structure, makes things convenient for its manufacturing.For the ease of transfer of ultrasonic energy, its oscillator is made taper type, installs for convenience and makes, and the big end of its diameter is connected with short cylinder, in order to reduce dynamic internal resistance, bonnet and sound head will have certain thickness, and the distribution equilibrium of trying one's best is again according to quality and frequency relation, design these concrete sizes, we adopt ￠ 12 * 1.25mm screw, because its existing certain intensity is loosening not too easily again.
Description of drawings.
Oscillator cutaway view in Fig. 1 supersonic wave cleaning machine.
Below in conjunction with description of drawings embodiment of the present utility model is described in further detail.
Anticipate as shown, oscillator in this supersonic wave cleaning machine, it includes sound head 1 and bonnet 2, between sound head 1 and the bonnet 2 piezoelectric ceramic piece and pole piece are housed, these are as traditional oscillator, do not have special character, its special character is that sound head 1 has taper type main body 11, its height 32mm, major diameter one end ￠ 64mm, minor diameter one end ￠ 38mm is connected with short cylinder 12 at the big end of its diameter, its height 7mm, have screw 13 at the little end center of diameter, bonnet 2 also is a cylinder accordingly, and its diameter ￠ 38.5mm has through hole 21 above, through-hole diameter ￠ 12.5mm, counterbore 22 diameter ￠ 19mm on the through hole, degree of depth 10mm uses screw ￠ 12 * 1.25 with sound head 1, piezoelectric ceramic piece and pole piece, bonnet 2 is connected in turn.
