Background

The novel ultrasonic knife handle component is as in the Chinese publication No. CN104526751, and is mainly characterized in that: comprises a knife handle shell, piezoelectric ceramics and a knife sleeve connected with the knife handle shell; the piezoelectric ceramic is used for converting electric energy into mechanical vibration energy and generating vibration; the cutter sleeve comprises an amplitude-variable rod part and a cutter head connected with the amplitude-variable rod part and used for machining a workpiece, wherein the amplitude-variable rod part is connected with piezoelectric ceramics and used for transmitting the vibration of the piezoelectric ceramics to the cutter head after amplitude amplification treatment; the piezoelectric ceramic is positioned in the cavity of the knife handle shell; the positive electrode and the negative electrode of the piezoelectric ceramic are both connected with wires, and the wires are both electrically connected with conductive pieces; the cutter handle shell is provided with two mounting grooves, and each mounting groove penetrates through the outer side wall of the cutter handle shell; the mounting groove is internally provided with an insulating sleeve, the two conductive pieces are correspondingly inserted into the insulating sleeves one by one, and the conductive pieces are separated from the handle shell by the insulating sleeves; the conductive piece is provided with an outer end surface exposed outside the cutter handle shell; the main disadvantages of the structure are as follows: when the designed positions of the conducting wire and the insulating sleeve are arranged on the main shaft, the contact of the conducting wire and the balance of the knife handle are poor due to a trace pollutant (micropollutant).

The conventional ultrasonic cutting blade holder for center processing machine is disclosed in Taiwan patent No. TWM454887, which is mainly characterized in that: the piezoelectric device comprises a cutter handle, a plurality of piezoelectric sheets and a joint rod, wherein the joint rod is fixed on the cutter handle, two ends of each piezoelectric sheet are divided into a positive pole end and a negative pole end, the piezoelectric sheets are stacked and fixed on the joint rod, the polar ends with the same polarity are adjacent, and the piezoelectric sheets generate ultrasonic-level vibration to drive the joint rod to linearly vibrate relative to the cutter handle; therefore, the joint rod clamps a cutting-off knife, and the cutting-off knife can be driven to generate ultrasonic-level linear vibration through the ultrasonic-level vibration of the piezoelectric sheets, so that the cutting-off knife can be used for cutting a workpiece; the main disadvantages in its constitution are: the assembly of the joint rod on the cutter handle can not control the balance precision and quality of the assembly.

Since complete tool shank balancing is never achieved, a suitable residual amount is allowed, and the amount of the residual amount depends on the size of the mechanical type and the cost of the balancing operation, so that a balance grade standard is provided.

In the invention, firstly, an impedance analyzer is used for measuring the piezoelectric impedance basic characteristic and the equivalent circuit value of the vibration generator system under a static state (low voltage), the response characteristic of the moving current to the resonance frequency of the vibration generator system is obtained by the concept of measuring the dynamic state (high voltage), and the two are compared and analyzed to establish the dynamic equivalent circuit of the vibration generator system under the actual application condition. And measuring the maximum mechanical vibration of the chuck caused by the vibration generator system after the vibration generator system is added into the resonant cavity by using an optical fiber displacement measuring module. By means of the measurement of the moving current and the amplitude, compared with the result of the impedance analyzer, the actual measurement result obtained at the resonance frequency is lower than that obtained by using the impedance analyzer, so that the static equivalent circuit is not suitable for practical application.

As shown in fig. 1 and 7, the negative contact electrode 63 is made of a copper alloy 71(copper alloy) plated with a hard gold alloy plating 72(hard gold alloy plating), the hard gold alloy plating film 72 mainly contains a crystalline structure (crystalline structure) of amorphous phase (amorphous phase) composed of fine crystals (micro crystals), the outer surface of which is formed in a sectional round bar shape of an outer step such that a small diameter portion 636 is integrally extended from a bottom surface 635 of a large diameter portion 634, and is loosely fitted into the positioning hole 52 of the contact electrode draw pin 5, a through hole 631 having an inner step upstream of the negative contact electrode 63, the upper section of the through hole 631 of the inner step having a larger size than the lower section of the through hole, a bottom end 632(bottom) disposed downstream of the negative contact electrode 63 and a thread end 633(free end of the thread) formed on the outer surface of the small diameter portion 636 of the negative contact electrode 63;

The two insulating sleeves 62 are respectively provided with a through hole 621 and respectively composed of the insulating sleeve 62 of an outer step and the insulating sleeve 62 with a gas hole 622 opened at one side edge, a concave portion 623(dent) is formed above the through hole 621 of the insulating sleeve 62 of the outer step, the insulating sleeve 62 of the outer step is arranged in the through hole 631 of the inner step at an upstream in a tight fit manner, and the insulating sleeve 62 with the gas hole 622 opened at a downstream of the through hole 631 is arranged in the tight fit manner;

the positive contact electrode 61 is made of a copper alloy 71(copper alloy) plated with a hard gold alloy plating film 72(hard gold alloy plating), the hard gold alloy plating film 72 mainly contains an amorphous phase crystalline structure (crystalline structure) composed of micro crystals, and is disposed in the two through holes 621 of the two insulating sleeves 62 at the upstream and the downstream, the positive contact electrode 61 has a large diameter and an inclined angle θ (enclosed angle) cone 611(cone) and a small diameter positive terminal cone 612, respectively, the inclined angle θ is preferably 150 degrees or less, preferably 135 degrees or less, and more preferably 120 degrees or less, the inclined angle 611 has the inclined angle and is accommodated in the recess 623(dent) above the through hole 621 of the insulating sleeve 62 at the outer step, the crystalline structure and the amorphous phase crystalline structure of the hard gold alloy plating film 72 can accelerate the current diffusion, a moving current applied to the positive contact electrode 61 is uniformly dispersed (spreading) and concentrated (current of current) to the positive contact electrode 61, so as to avoid the current crowding (crowning) causing a high voltage;

The nut 65 is fastened to the threaded protruding end 633 of the contact negative electrode 63 to adjust the position of the contact negative electrode 63 at an upper limit (upper bounds) of the contact electrode pull stud 5.

The positive contact electrode 61 is connected to the positive plate 32 of the vibration generator system 3 by a first wire 54, the negative contact electrode 63 is connected to the negative plate 34 of the vibration generator system 3 by a second wire 55, the negative plate 34 provides a negative earth (minus earth) effect, and the positive contact electrode 61 of the contact electrode 6 inputs a movement current (migration current) to drive the vibration generator system 3 to generate an amplitude to drive the chuck 25 to cause mechanical vibration (mechanical vibration). Since the logarithm of the moving current and the current intensity (current) are in a linear relationship, in order to maintain the sufficient energy required by the vibration generator system 3 for the reaction rate, the hard gold alloy coating 72 plated on the cone 611 contacting the positive electrode 61 mainly contains the crystal structure of amorphous phase formed by micro-crystals for uniformly applying the current intensity (current) of the moving current to uniformly disperse and concentrate the moving current, so as to avoid the current crowding (current) from causing the voltage to be too high, thereby affecting the moving current transfer rate and maintaining the reaction rate of the vibration generator system 3.

The contact negative electrode 63 received in the positioning hole 52 has a sectional round bar shape with an outer surface formed with an outer step, and has a large diameter portion 634, a bottom surface 635, and a small diameter portion 636, the small diameter portion 636 being integrally formed extending from the bottom surface 635 of the large diameter portion 634.

The upper end of the elastic body 64 composed of a compression spring abuts against the bottom surface 635 of the contact negative electrode 63. The elastic body 64 further has a lower end abutting against one of the stepped positioning hole 52 and the upper and lower limits 53 receive the elastic body 64, so that the outer surface of the elastic body 64 is supported by the inner surface of the upper and lower limits 53. And then, the nut 65 is locked on the threaded protruding end 633 of the contact negative electrode 63. Accordingly, the contact negative electrode 63 is not detached from the contact electrode tab 5. The contact negative electrode 63 is allowed to slide in the upper and lower limits 53 of the positioning hole 52 of the contact electrode pull stud 5 in a loose fit manner, or the contact electrode 6 is allowed to form a stroke (stroke) for moving a position by receiving a pressure.

As can be seen from fig. 7, the insulating sleeve 62 of an outer step (outer step) is received in the through hole 631 of the inner step upstream of the contact negative electrode 63, and the upper section of the bore of the insulating sleeve 62 of the outer step has a larger size than the lower section of the bore, so that the insulating sleeve 62 of the outer step upstream of the through hole 631 does not enter the inside of the through hole 631. The downstream of the through hole 631 receives the insulating sleeve 62 with an air hole 622 opened on the side, and the air hole 622 is used to exhaust the air in the through hole 631, so as to avoid air resistance (air resistance) generated when the contact positive electrode 61 is disposed in the through hole 621 of the two insulating sleeves 62 in the upstream and downstream directions and slides.

Further, the hard gold alloy plating film 72 of the contact positive electrode 61 and the contact negative electrode 63 is formed by adding cobalt, nickel, etc. to gold, and the hardness of the hard gold alloy plating film 72 can be improved without lowering the original good conductivity and chemical stability of gold. The hard gold alloy plating film 72 has a crystal structure in which fine crystals (10 to 30nm) of hard gold are aggregated, and can be regarded as a substance having a hardness (Knoop hardness) of HK200 at which the lowest limit necessary for obtaining the wear resistance required for the contact material of the positive contact electrode 61 and the negative contact electrode 63 can be obtained due to the crystal structure. The fine crystal of the hard gold alloy plating film 72 of the present invention is a crystal structure of the hard gold alloy plating film 72 that does not lower the hardness, although the crystal structure of the amorphous phase can maintain the excellent specific resistance and chemical stability inherent in hard gold in the practical and reliable operation, and further enhance the hardness and wear resistance of the hard gold alloy plating film 72.

The vibration generator system 3 may consist of the same or similar type of coating 41 subjected to a coating operation. Coating operation the vibration generator system 3 is advantageously configured for dispensing the coating 41 in the appropriate stripe shape and width during the overlay process and bonding process. Further, the coating 41 is made of more than two layers of stripe shapes and widths. As used herein, a "layer" refers to a plurality or group of bonding compounds that share similar characteristics, including, but not limited to, similar composition, size, function, and/or coating pattern. Thus, while the coating 41 is described and illustrated in terms of a few examples of bonding compounds for a coating operation, it is contemplated that the coating 41 may be applied together in a staggered layered configuration or staggered configuration and a plurality of stripes extending along the appearance in a curing action.

Referring to fig. 15, an inorganic colloid 42(inorganic colloid) is fed to a gap between the resonant cavity 13 and the vibration generator system 3 by a filling device (filling device) using an impulse response (impulse response) and a filling pulse (filler pulse), and the inorganic colloid 42 is filled from the second side 15 to the gap between the first side 14, the pulsating response and the filling pulse can balance the flow rate, so that no bubble (bubble) or air hole (air hole) is generated in the gap, and is kept in a colloidal stationary phase (colloidal stationary phase) flowing and sealing an appearance (external finish) of the first piezoelectric crystal 31, the positive plate 32, the second piezoelectric crystal 33, the negative plate 34, the balance weight 35 and the round nut 36 with a fixed lock hole on the side surface of the vibration generator system 3 to provide proper package protection against electrical short circuit and dust (dust) contamination. The inorganic gel 42 is formed by a solid-state process configured to bear a vibration potential (shear deformation) applied in the vertical direction and a shear deformation (shear deformation) applied in the horizontal direction by the first piezoelectric crystal 31, the positive electrode plate 32, the second piezoelectric crystal 33, the negative electrode plate 34, the weight 35 and the side-face-fixed-lockhole round nut 36 of the vibration generator system 3; in the present embodiment, the thickness of the inorganic colloid 42 (the distance from the outer surface of the vibration generator system 3 to the inner surface of the resonant cavity 13) within the resonant cavity 13 is equal to the gap, so as to achieve the flow rate balance between the first side 14 and the second side 15. Further, the amount of the starting material or the composition of the components used for the inorganic colloid 42, the difference in the source or purity, or the composition of the initial concentration or the mixing ratio can be varied, and the magnitude of the vibration amount of the ultrasonic tool shank and the phase angle position thereof can be effectively adjusted, as shown in fig. 16 to 17. Alternatively, as shown in fig. 18, the coating layer 41 and a plurality of layers of the inorganic colloid 42 can be used.

The gap between the resonant cavity 13 and the vibration generator system 3 includes a constricted passage through which the inorganic colloid 42 flows. For the purposes of this disclosure, the constricting channel is intended to mean any narrowing in at least one dimension. The constricted passage may be formed by: (A) one side of the resonant cavity 13 has a protrusion protruding towards one side of the vibration generator system 3, (B) both sides of the resonant cavity 13 have at least one protrusion protruding towards one side of the vibration generator system 3, wherein such plurality of protrusions are aligned with each other, or staggered along the gap, or (C) at least one cylinder or column protruding between two walls of the resonant cavity 13, to distinguish the slower velocity flow through the gap. In one embodiment, the constricting channel includes a region of the gap having a smaller cross-sectional area than adjacent regions of the gap on the upstream first side 14 and downstream second side 15 of the constricting channel. The size or dimension of the constricting channels is limited at any point in time to allow for balancing of the inorganic gel 42 through the constricting channels, which facilitates balancing of the respective flow rates through the constricting channels 42. The ease of individual flow rate changes is indicative of the nature, parameters or characteristics of the inorganic colloid 42 passing through the constricted passages.

The filling device enters the first side 14 of the resonant cavity 13 through the channel 12 of the tool sheath 1, and then by applying the pulse response and the filling pulse wave (the pulse response with lower power and the filling pulse wave with longer power, or the pulse response with higher power and the filling pulse wave with shorter length) to the inorganic colloid 42, the inorganic colloid 42 generates vertical fluid pressure (vertical fluid pressure) to flow into the gap between the resonant cavity 13 and the vibration generator system 3 or the shrinking channel, so that when the inorganic colloid 42 flows from the first side 14 to the second side 15, the bubbles or air holes contained in the inorganic colloid 42 can be removed when the pulse response and the filling pulse wave are activated, and the state of removing the bubbles or air holes can be maintained in the inorganic colloid 42. As a by-product, a suitable amount of heat may be generated. Preferably, a lower power of the pulse response and a longer fill pulse to provide a pulse of heat to the inorganic gel 42 without forming bubbles or voids. If a partial or complete blockage of the inorganic gel 42 occurs in the flow, a higher power of the pulse response and a relatively short filling pulse can be used to clear the blockage.

The inorganic colloid 42 flows into the gap or the angle of the contraction channel is parallel to the center of mass, no air bubbles or pores are generated, and if the inflow angle is not 90 degrees, the flow rate is changed. Therefore, the inflow angle of the inorganic colloid 42 is required to be at least more than 0 degree and 90 degrees or less, preferably 50 to 90 degrees, and more preferably 70 to 90 degrees. In addition, although at least one inorganic colloid 42 is used to remove air bubbles or air holes by the vertical fluid pressure, it is preferable that two or more inorganic colloids 42 are formed and arranged so that the vertical fluid pressure of the inorganic colloids 42 flowing in is uniform in order to effectively remove air bubbles or air holes. When three or more inorganic colloids 42 are formed, the flow rate balance can be arranged three-dimensionally. Fluid control used in the inorganic gel 42 is achieved by achieving a natural balance between vertical fluid pressure and fluid flow acceleration, whereby the gap or constricted, curved portion of the constricted passage creates a pressure drop associated with dissipation.

In the present embodiment, the contact positive electrode 61 and the contact negative electrode 63 are made of conductive material or made of conductor, and the contact positive electrode 61 and the contact negative electrode 63 can electrically connect the positive plate 32 and the negative plate 34 of the vibration generator system 3; the negative contact electrode 63 can be electrically connected to at least one grounding path (such as the knife sheath 1) to enlarge the grounding area, so as to help guide the noise interference of the gap between the resonant cavity 13 and the vibration generator system 3 to the ground, thereby obtaining good electrical characteristics.

In addition, preferably, the contact negative electrode 63 surrounds and encloses the contact positive electrode 61, the contact negative electrode 63 and the contact positive electrode 61 are separated by the insulating sleeve 62, such that the contact negative electrode 63 and the contact positive electrode 61 are separated and electrically isolated from each other, and the contact negative electrodes 63 are respectively used for at least one second wire 55 to electrically connect to the negative electrode 34 of the vibration generator system 3. In the embodiment, the contact positive electrode 61 and the contact negative electrode 63 are formed by performing a surface treatment such as a gold chemical treatment on copper or a copper alloy 71, but the invention is not limited thereto, and other surface treatments may be used for other applications, such as: using surface treatment methods such as nickel plating, nickel-cobalt plating, nickel-zinc plating, and gold plating to form the contact positive electrode 61 and the contact negative electrode 63 that can be electrically connected and welded; alternatively, other methods may be used to dispose or form the contact positive electrode 61 and the contact negative electrode 63 on the surface of the copper or copper alloy 71 for electrically connecting or welding. It is worth mentioning that, by the design that each contact negative electrode 63 surrounds each contact positive electrode 61 respectively, the electrical isolation effect between the contact positive electrodes 61 can be improved, and the leakage current interaction effect generated between the contact positive electrodes during the test process can be reduced, so as to improve the electrical characteristics and the test accuracy, so that the electrical path is protected more perfectly, in addition, by the design of the contact negative electrode 63, the effect of conducting the noise interference or static electricity generated in the environment away from the contact positive electrode 61 can be achieved, so that the test path is protected and noise interference is reduced, the electrical characteristics of the contact electrode pull plug 5 are improved, and the distortion of the contact result is avoided.

When the vibration generator system 3 works under an external high voltage through the contact electrode tie bolt 5, the resonance frequency of the vibration generator system 3 is shifted by the temperature rise phenomenon generated by the vibration generator system 3 and the external prestress, so that the mechanical power output by the chuck 25 is reduced. On the other hand, since the amplitude of the vibration generated by the vibration generator system 3 itself is not large, the resonant cavity 13 is added to amplify the mechanical vibration (mechanical vibration) of the chuck 25.

In the present invention, an impedance analyzer is used to measure the piezoelectric impedance basic characteristic and the equivalent circuit value of the vibration generator system 3 under the static state (low voltage), and the response characteristic of the moving current to the resonance frequency of the vibration generator system 3 is obtained by the concept of measuring the dynamic state (high voltage), and the two are compared to analyze, so as to establish the dynamic equivalent circuit of the vibration generator system 3 under the actual application condition. And the maximum mechanical vibration caused by the vibration generator system 3 to the chuck 25 after being added to the resonant cavity 13 is measured using a fiber displacement measurement module. By means of the measurement of the moving current and the amplitude, compared with the result of the impedance analyzer, the actual measurement result obtained at the resonance frequency is lower than that obtained by using the impedance analyzer, so that the static equivalent circuit is not suitable for practical application. The result of simulation is closer to the actual measurement with a dynamic equivalent circuit. In addition, the resonance cavity 13 of the stepped alloy steel is added to the vibration generator system 3 to obtain larger mechanical vibration (about 3-6 times of the original vibration), so that the working efficiency of the vibration generator system 3 is increased, and the resonance cavity 13 can be regarded as a series connection of a negative resistance and an inductance on an equivalent circuit.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
