[0004] In traditional ultrasonic clamps, the ultrasonic vibrations generated by the ultrasonic transducer are transmitted to the vibration table through the ultrasonic commutation block. However, due to its own structural design, during the transmission of the ultrasonic vibrations, part of the ultrasonic vibrations may be transmitted to components other than the vibration table, such as the outer casing.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The various technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the various technical features in the above-described embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] See also Figures 1 to 3 The ultrasonic fixture 10 in one embodiment is used to assist in processing hard and brittle materials such as mobile phone glass cover plates by ultrasonic means. During operation, the mobile phone glass cover plate is fixed on the ultrasonic fixture 10, and ultrasonic vibration is transmitted to the mobile phone glass cover plate through the ultrasonic fixture 10. At the same time, the CNC cutter head cuts the mobile phone glass cover plate. The ultrasonic fixture 10 includes a base 100, a housing 200, an ultrasonic commutation block 300, an ultrasonic transducer 400, a vibration table 500, and a workpiece carrier 600.

[0036] Specifically, the housing 200 is covered on the base 100, and together with the base 100, forms a receiving cavity 100a. For example, the base 100 is a plate-like structure, the housing 200 is a shell-like structure, the base 100 is arranged at the bottom of the housing 200, and seals the bottom of the housing 200. Optionally, the base 100 is fastened to the bottom of the housing 200 by fasteners such as screws. A sealing member may also be provided between the base 100 and the housing 200 to increase the sealing between the base 100 and the housing 200.

[0037] Furthermore, a mounting plate 210 is provided at the bottom of the housing 200, and a mounting hole 211 is provided on the mounting plate 210, and a fastener such as a screw is inserted into the mounting hole 211 to fix the housing 200 on the machine tool workbench. For example, the mounting plate 210 can be integrally formed with the housing 200, and the mounting hole 211 can be a long strip hole, which is convenient for adjusting the position of the ultrasonic fixture 10.

[0038] The ultrasonic commutation block 300 is fixed on the base 100, and the ultrasonic commutation block 300 is located in the accommodating cavity 100a. Specifically, a vibration input part 310 is provided on opposite sides of the ultrasonic commutation block 300, a vibration output part 320 is provided on the top of the ultrasonic commutation block 300, and at least one commutation amplification hole 330 and an even number of energy-gathering amplification holes 340 are provided inside the ultrasonic commutation block 300. The even number of energy-gathering amplification holes 340 are arranged symmetrically about the central axis of the ultrasonic commutation block 300, and the spacing between the energy-gathering amplification holes 340 on both sides of the central axis gradually decreases in the vertical upward direction. The commutation amplification hole 330 is used to perform the first commutation and amplification of the ultrasonic vibration in the horizontal direction, and the energy-gathering amplification hole 340 is used to perform the second commutation and amplification of the ultrasonic vibration. Since the spacing between the energy-gathering amplification holes 340 on both sides of the central axis gradually decreases in the vertical upward direction, the energy-gathering amplification holes 340 converge on the vibration output part 320 after the second commutation of the ultrasonic vibration, and play a certain energy-gathering role.

[0039] The ultrasonic transducer 400 is located in the accommodating cavity 100a, and the ultrasonic transducer 400 is installed on the vibration input part 310. Specifically, there are two ultrasonic transducers 400, and the two ultrasonic transducers 400 are respectively installed on the two vibration input parts 310. Therefore, the horizontal ultrasonic vibration generated by the ultrasonic transducer 400 is transmitted to the ultrasonic commutation block 300 through the vibration input part 310, and is output to the vibration table 500 by the vibration output part 320 after being commutated and amplified by the ultrasonic commutation block 300.

[0040] Since the vibration output part 320 is at the top of the ultrasonic commutation block 300, at least one commutation amplifying hole 330 and an even number of energy focusing amplifying holes 340 are opened inside the ultrasonic commutation block 300, and the even number of energy focusing amplifying holes 340 are symmetrically arranged about the central axis of the ultrasonic commutation block 300, and the spacing between the energy focusing amplifying holes 340 on both sides of the central axis gradually decreases in the vertical upward direction. Therefore, the ultrasonic vibration generated by the ultrasonic transducer 400 is transmitted from the vibration input part 310 in the horizontal direction to the ultrasonic commutation block 300, and the ultrasonic wave is commutated and amplified through the commutation amplifying hole 330, and then transmitted to the energy focusing amplifying hole 340 for further energy focusing and amplification, and then transmitted to the vibration output part 320 for output, which can not only convert the horizontal ultrasonic vibration into the vertical direction, effectively reduce the height of the ultrasonic clamp 10 from the overall structural form, but also can focus and amplify the ultrasonic vibration, reduce the height of the ultrasonic clamp 10 from the size, and reduce the overall height of the ultrasonic clamp 10 by combining the structure and size to be suitable for CNC machining machine tools.

[0041] It should be noted that the "horizontal direction" and "vertical direction" in this article are only used as an example to illustrate that the ultrasonic clamp 10 is horizontally installed on the machine tool workbench in the figure, but this does not limit the scope of protection. For example, when the ultrasonic clamp 10 is vertically installed on the machine tool workbench, the "horizontal direction" and "vertical direction" also need to be adjusted according to the installation direction of the ultrasonic clamp 10.

[0042] Furthermore, each reversing amplifying hole 330 is arranged at intervals in the vertical direction, and an even number of energy-focusing amplifying holes 340 are axially symmetrically located on opposite sides of the reversing amplifying hole 330, and the lowest point of the energy-focusing amplifying hole 340 located at the bottom is lower than the highest point of the reversing amplifying hole 330 located at the top, and the highest point of the energy-focusing amplifying hole 340 located at the top is higher than the highest point of the reversing amplifying hole 330 located at the top. That is, the top reversing amplifying hole 330 and the bottom energy-focusing amplifying hole 340 overlap in space in the horizontal direction. The purpose of such a setting is to further improve the amplification effect of the energy-focusing amplifying hole 340.

[0043] See also Figures 3 to 8 In the embodiment shown in the figure, the number of the reversing amplifying hole 330 is one, and the central axis of the reversing amplifying hole 330 coincides with the central axis of the ultrasonic reversing block 300, and the number of the energy focusing amplifying holes 340 is two, and the two energy focusing amplifying holes 340 are symmetrical about the central axis. Setting the energy focusing amplifying holes 340 to be symmetrical about the central axis is conducive to more uniform transmission of ultrasonic vibrations on the left and right sides to the vibration table 500. Setting the number of the reversing amplifying holes 330 to one and the number of the energy focusing amplifying holes 340 to two is conducive to simplifying the structure and reducing the difficulty of manufacturing.

[0044] Furthermore, the two energy focusing amplifying holes 340 are located on opposite sides of the reversing amplifying hole 330, and the lowest point of the energy focusing amplifying hole 340 is lower than the highest point of the reversing amplifying hole 330, and the highest point of the energy focusing amplifying hole 340 is higher than the highest point of the reversing amplifying hole 330. That is, the reversing amplifying hole 330 and the energy focusing amplifying hole 340 overlap in space along the horizontal direction, so it is easier for the ultrasonic vibration to be transmitted from the side wall of the reversing amplifying hole 330 to the side wall of the energy focusing amplifying hole 340, and combined with the energy focusing effect of the energy focusing amplifying hole 340, the ultrasonic vibration can be better transmitted to the vibration output part 320.

[0045] Of course, in other embodiments, the number of the reversing amplifying holes 330 can also be two, three, etc., and the number of the energy focusing amplifying holes 340 can also be four, six, etc.

[0046] Please continue reading Figure 7 The ultrasonic commutation block 300 has a first side surface 301, a second side surface 302, a third side surface 303 and a fourth side surface 304. The first side surface 301 is arranged opposite to the second side surface 302, and the third side surface 303 is arranged opposite to the fourth side surface 304. The first side surface 301 is adjacent to the third side surface 303 and the fourth side surface 304, and the second side surface 302 is adjacent to the third side surface 303 and the fourth side surface 304. The first side surface 301 and the second side surface 302 are provided with an assembly hole 350, and the assembly hole 350 is connected with the commutation amplifying hole 330. The commutation amplifying hole 330 and the energy focusing amplifying hole 340 pass through the third side surface 303 and the fourth side surface 304, so that the ultrasonic vibration can be transmitted more evenly and the processing accuracy is improved.

[0047] Furthermore, an inclined surface 360 ​​is provided between the first side surface 301 and the top of the ultrasonic commutation block 300, and between the second side surface 302 and the top of the ultrasonic commutation block 300, and the distance between the two inclined surfaces 360 gradually decreases in the vertical upward direction. In some embodiments, the inclined surface 360 ​​is provided, and when the ultrasonic vibration is transmitted from the ultrasonic transducer 400 to the ultrasonic commutation block 300, since the distance between the two inclined surfaces 360 gradually decreases in the vertical upward direction, it can further play an energy focusing and amplification role.

[0048] Furthermore, the inclination angle of the inclined surface 360 ​​differs from the inclination angle of the energy focusing amplifying hole 340 by 0°-5°, so the inclined surface 360 ​​and the energy focusing amplifying hole 340 are not arranged in parallel, and the transmission direction of the ultrasonic vibration can be further reversed for the third time to ensure that the ultrasonic vibration is output along the vibration output part 320. For example, in this embodiment, the inclination angle of the inclined surface 360 ​​differs from the inclination angle of the energy focusing amplifying hole 340 by 4.5°.

[0049] A first vacuum adsorption hole 370 is provided on the top of the ultrasonic commutation block 300, and a second vacuum adsorption hole 380 is provided on the side of the ultrasonic commutation block 300 adjacent to the vibration input part 310, and the first vacuum adsorption hole 370 is connected to the second vacuum adsorption hole 380. Therefore, the ultrasonic fixture 10 adsorbs and fixes the workpiece by vacuum adsorption.

[0050] The ultrasonic transducer 400 includes a first piezoelectric sheet 410 , a second piezoelectric sheet 420 , a first electrode sheet 430 , a second electrode sheet 440 and a fastener 450 . The fastener 450 is sequentially inserted into the first piezoelectric sheet 410 , the first electrode sheet 420 , the second piezoelectric sheet 430 and the second electrode sheet 440 and fastened to the vibration input part 310 .

[0051] The top surface of the housing 200 is provided with an opening 201, and the vibration output unit 320 protrudes from the housing 200 through the opening 201. The vibration table 500 is fixed on the vibration output unit 320, and there is a distance between the vibration table 500 and the housing 200. The workpiece carrier 600 is fixed on the vibration table 500, and the workpiece carrier 600 is used to place the workpiece to be processed, such as a mobile phone glass cover. For example, the workpiece carrier 600 can be fixed to the vibration table 500 by fasteners such as screws. Of course, in other embodiments, the workpiece carrier 600 can also be integrally formed with the vibration table 500.

[0052] The ultrasonic vibration isolation structure is defined to include the ultrasonic commutation block 300 and the housing 200 mentioned above. Furthermore, a bearing portion 390 is also provided on the top of the ultrasonic commutation block 300, and the bearing portion 390 is located on the peripheral side of the vibration output portion 320. For example, the bearing portion 390 can be located on the peripheral side of one end of the vibration output portion 320. The housing 200 has a top plate 220 and a peripheral wall 230, an opening 201 is opened on the top plate 220, and a vibration reduction arm 202 is protruded on the inner side wall of the opening 201. The thickness of the vibration reduction arm 202 is less than the thickness of the top plate 220, and the vibration reduction arm 202 is overlapped on the bearing portion 390, and the vibration output portion 320 protrudes from the housing 200 through the opening 201. The top plate 220 and the vibration output portion 320 are spaced apart.

[0053] After assembly, the vibration reduction arm 202 is overlapped on the bearing part 390, and the vibration output part 320 protrudes from the housing 200 through the opening 201. During operation, the ultrasonic vibration is transmitted to the vibration table 500 through the vibration output part 320. Since the housing 200 is overlapped on the bearing part 390 through the vibration reduction arm 202, the ultrasonic vibration of the vibration output part 320 will be transmitted to the vibration reduction arm 202, and the thickness of the vibration reduction arm 202 is less than the thickness of the top plate 220 of the housing 200. Therefore, the vibration reduction arm 202 is more likely to deform than the top plate 220 of the housing 200, and the ultrasonic vibration transmitted from the vibration output part 320 is offset. Therefore, the ultrasonic vibration transmitted from the vibration output part 320 will not or rarely be transmitted to the housing 200, thereby ensuring that the housing 200 will not be affected by the ultrasonic vibration, thereby ensuring the processing accuracy.

[0054] In addition, in the illustrated embodiment, since the vibration output part 320 is at the top of the ultrasonic commutation block 300 and the vibration input part 310 is at the bottom of the ultrasonic commutation block 300, combined with the zero-point vibration principle, the zero-point vibration is roughly located at or near the contact point between the vibration-damping arm 202 and the bearing part 390. Therefore, the vibration-damping arm 202 is arranged on the inner wall of the opening 201 of the outer shell 200. The ultrasonic vibration received by the vibration-damping arm 202 here is very small or even close to the zero point, which is more conducive to avoiding the transmission of the ultrasonic vibration to the outer shell 200.

[0055] Furthermore, the vibration damping arm 202 has a lap joint surface 203 and a welding surface 204. The vibration damping arm 202 is lap jointed on the bearing portion 390 through the lap joint surface 203, and the vibration damping arm 202 is welded to the side of the vibration output portion 320 through the welding surface 204. Therefore, the vibration damping arm 202 is fixed to the ultrasonic commutation block 300 by welding. For example, a semi-V-shaped groove can be formed on the vibration damping arm 202, and a semi-V-shaped groove can be formed on the vibration output portion 320. The two semi-V-shaped grooves constitute a V-shaped groove, and then the V-shaped groove is filled with solder for welding, which can improve the firmness between the vibration damping arm 202 and the ultrasonic commutation block 300.

[0056] Furthermore, a boss 205 is protruding from the top surface of the vibration damping arm 202, the opening 201 passes through the boss 205, the inner side wall of the boss 205 is flush with the welding surface 204, and the top surface of the boss 205 is lower than the top surface of the vibration output part 320. Therefore, the boss 205 is provided to increase the contact area between the vibration damping arm 202 and the vibration output part 320 to improve the firmness between the vibration damping arm 202 and the ultrasonic commutation block 300, and the top surface of the boss 205 is lower than the top surface of the vibration output part 320, so that the boss 205 will not directly contact the vibration table 500, preventing the ultrasonic vibration of the vibration table 500 from being transmitted to the housing 200 through the boss 205. The length of the boss 205 can be less than the thickness of the vibration damping arm 202.

[0057] Of course, in other embodiments, the damping arm 202 is located above the inner side wall of the opening 201, and the top surface of the damping arm 202 is flush with the top surface of the housing 200. For example, the damping arm 202 can be formed by slotting the bottom of the top plate 220 of the housing 200, thereby simplifying the molding process.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
