Referring to fig. 1 to 3, an ultrasonic clamp 10 according to an embodiment is used for processing a hard and brittle material such as a mobile phone glass cover plate in an ultrasonic mode, when the ultrasonic clamp 10 is in operation, the mobile phone glass cover plate is fixed on the ultrasonic clamp 10, ultrasonic vibration is transmitted to the mobile phone glass cover plate through the ultrasonic clamp 10, and a CNC tool bit cuts the mobile phone glass cover plate. The ultrasonic clamp 10 includes a base 100, a housing 200, an ultrasonic reversing block 300, an ultrasonic transducer 400, a vibration table 500 and a workpiece bearing table 600.
Specifically, the housing 200 covers the base 100 and encloses an accommodating cavity 100a together with the base 100. For example, the base 100 has a plate-like structure, the housing 200 has a shell-like structure, and the base 100 is disposed at the bottom of the housing 200 and seals the bottom of the housing 200. Alternatively, the base 100 is fastened to the bottom of the housing 200 by a fastener such as a screw. A sealing member may be further disposed between the base 100 and the housing 200 to increase the sealability between the base 100 and the housing 200.
Further, the bottom of the housing 200 is further provided with a mounting plate 210, the mounting plate 210 is provided with a mounting hole 211, and the mounting hole 211 is penetrated by a fastener such as a screw to fix the housing 200 on the machine tool workbench. For example, the mounting plate 210 may be integrally formed with the housing 200, and the mounting hole 211 may be an elongated hole to facilitate adjustment of the position of the ultrasonic clamp 10.
The ultrasonic reversing block 300 is fixed on the base 100, and the ultrasonic reversing block 300 is located in the accommodating cavity 100 a. Specifically, the two opposite sides of the ultrasonic reversing block 300 are provided with vibration input parts 310, the top of the ultrasonic reversing block 300 is provided with a vibration output part 320, at least one reversing amplification hole 330 and an even number of energy-collecting amplification holes 340 are formed in the ultrasonic reversing block 300, the even number of energy-collecting amplification holes 340 are axially and symmetrically arranged relative to the central axis of the ultrasonic reversing block 300, and the distance between the energy-collecting amplification holes 340 on the two sides of the central axis is gradually reduced along the vertical upward direction. The reversing amplification hole 330 is used for reversing and amplifying the ultrasonic vibration in the horizontal direction for the first time, the energy-collecting amplification holes 340 are used for reversing and amplifying the ultrasonic vibration for the second time, and the distance between the energy-collecting amplification holes 340 on the two sides of the central shaft is gradually reduced along the vertical upward direction, so that the energy-collecting amplification holes 340 perform the second time of reversing on the ultrasonic vibration and then converge on the vibration output part 320, and a certain energy-collecting effect is achieved.
The ultrasonic transducer 400 is located in the accommodating chamber 100a, and the ultrasonic transducer 400 is mounted to the vibration input portion 310. Specifically, the number of the ultrasonic transducers 400 is two, and the two ultrasonic transducers 400 are respectively mounted on the two vibration input portions 310. Therefore, the ultrasonic vibration in the horizontal direction generated by the ultrasonic transducer 400 is transmitted to the ultrasonic wave reversing block 300 through the vibration input portion 310, and is reversed and amplified by the ultrasonic wave reversing block 300 and then output to the vibration table 500 through the vibration output portion 320.
Because the vibration output part 320 is arranged at the top of the ultrasonic reversing block 300, at least one reversing amplifying hole 330 and even energy-gathering amplifying holes 340 are arranged in the ultrasonic reversing block 300, the even energy-gathering amplifying holes 340 are arranged in an axial symmetry way around the central axis of the ultrasonic reversing block 300, and the distance between the energy-gathering amplifying holes 340 at two sides of the central axis is gradually reduced along the vertical upward direction, the ultrasonic vibration generated by the ultrasonic transducer 400 is transmitted to the ultrasonic reversing block 300 from the vibration input part 310 in the horizontal direction, the ultrasonic is reversed and amplified through the reversing amplifying holes 330, then transmitted to the energy-gathering amplifying holes 340 for further energy gathering and amplification, and then transmitted to the vibration output part 320 for output, the ultrasonic vibration in the horizontal direction can be converted into the vertical direction, the height of the ultrasonic clamp 10 is effectively reduced from the overall structure form, and the ultrasonic vibration can be subjected to energy gathering and amplification, the height of the ultrasonic clamp 10 is reduced in size, and the overall height of the ultrasonic clamp 10 is reduced in combination with both structure and size so as to be suitable for CNC processing machines.
The "horizontal direction" and "vertical direction" in this document are only examples of the ultrasonic jig 10 being horizontally mounted on the machine tool table in the drawings, but this does not limit the scope of protection. For example, when the ultrasonic clamp 10 is vertically mounted on the machine tool table, "horizontal direction" and "vertical direction" also need to be adjusted appropriately in accordance with the mounting direction of the ultrasonic clamp 10.
Furthermore, the inverting amplifying holes 330 are arranged at intervals in the vertical direction, the even number of energy collecting amplifying holes 340 are axisymmetrically located at two opposite sides of the inverting amplifying holes 330, the lowest position of the energy collecting amplifying hole 340 located at the lowermost position is lower than the highest position of the inverting amplifying hole 330 located at the uppermost position, and the highest position of the energy collecting amplifying hole 340 located at the uppermost position is higher than the highest position of the inverting amplifying hole 330 located at the uppermost position. That is, the uppermost inverting amplifying hole 330 and the lowermost energy collecting amplifying hole 340 are spatially overlapped in the horizontal direction. The purpose of this is to further enhance the amplification effect of the shaped energy amplifying hole 340.
Referring to fig. 3 to 8, in the embodiment shown in the drawings, the number of the inverting amplifying holes 330 is one, the central axis of the inverting amplifying holes 330 coincides with the central axis of the ultrasonic wave inverting block 300, the number of the energy collecting amplifying holes 340 is two, and the two energy collecting amplifying holes 340 are axisymmetric with respect to the central axis. The energy-gathering and amplifying holes 340 are arranged to be axisymmetric with respect to the central axis, which is beneficial to the ultrasonic vibration on the left and right sides to be more uniformly transmitted to the vibration table 500. The number of the reversing amplifying holes 330 is set to be one, and the number of the energy collecting amplifying holes 340 is set to be two, so that the structure is simplified, and the manufacturing difficulty is reduced.
Further, the two energy collecting and amplifying holes 340 are located on two opposite sides of the reversing amplifying hole 330, the lowest position of the energy collecting and amplifying holes 340 is lower than the highest position of the reversing amplifying hole 330, and the highest position of the energy collecting and amplifying holes 340 is higher than the highest position of the reversing amplifying hole 330. That is, the inverting amplification hole 330 and the energy collecting amplification hole 340 are spatially overlapped in the horizontal direction, so that the ultrasonic vibration is more easily transmitted from the side wall of the inverting amplification hole 330 to the side wall of the energy collecting amplification hole 340, and the ultrasonic vibration can be better transmitted to the vibration output unit 320 by combining the energy collecting effect of the energy collecting amplification hole 340.
Of course, in other embodiments, the number of the commutating amplifying holes 330 may also be two, three, etc., and the number of the energy concentrating amplifying holes 340 may also be four, six, etc.
With reference to fig. 7, the ultrasonic wave reversing block 300 has a first side 301, a second side 302, a third side 303 and a fourth side 304, the first side 301 is opposite to the second side 302, the third side 303 is opposite to the fourth side 304, the first side 301 is adjacent to the third side 303 and the fourth side 304, the second side 302 is adjacent to the third side 303 and the fourth side 304, the first side 301 and the second side 302 are provided with assembling holes 350, the assembling holes 350 are communicated with the reversing amplifying hole 330, and the reversing amplifying hole 330 and the energy concentrating amplifying hole 340 penetrate through the third side 303 and the fourth side 304, so that the ultrasonic wave vibration can be transmitted more uniformly, and the processing precision is improved.
Further, inclined surfaces 360 are arranged between the first side surface 301 and the top of the ultrasonic reversing block 300 and between the second side surface 302 and the top of the ultrasonic reversing block 300, and the distance between the two inclined surfaces 360 is gradually reduced along the vertical upward direction. In some embodiments, the inclined surfaces 360 are provided, and after the ultrasonic vibration is transmitted from the ultrasonic transducer 400 to the ultrasonic wave reversing block 300, the distance between the two inclined surfaces 360 is gradually reduced along the vertical upward direction, so that the energy gathering and amplifying effects can be further achieved.
Further, the difference between the inclination angle of the inclined surface 360 and the inclination angle of the energy-collecting and amplifying hole 340 is 0 to 5 degrees, so that the inclined surface 360 and the energy-collecting and amplifying hole 340 are not parallel to each other, the transmission direction of the ultrasonic vibration can be further reversed for the third time, and the ultrasonic vibration is ensured to be output along the vibration output part 320. For example, in the present embodiment, the inclination angle of the inclined surface 360 is different from the inclination angle of the energy concentrating aperture 340 by 4.5 °.
The top of the ultrasonic reversing block 300 is provided with a first vacuum adsorption hole 370, the side surface of the ultrasonic reversing block 300 adjacent to the vibration input part 310 is provided with a second vacuum adsorption hole 380, and the first vacuum adsorption hole 370 is communicated with the second vacuum adsorption hole 380. Therefore, the ultrasonic jig 10 fixes the workpiece by suction by vacuum suction.
The ultrasonic transducer 400 includes a first piezoelectric plate 410, a second piezoelectric plate 420, a first electrode plate 430, a second electrode plate 440, and a fastener 450, wherein the fastener 450 is sequentially inserted into the first piezoelectric plate 410, the first electrode plate 420, the second piezoelectric plate 430, and the second electrode plate 440 and fastened to the vibration input portion 310.
The top surface of the housing 200 is provided with an opening 201, the vibration output part 320 protrudes out of the housing 200 through the opening 201, the vibration table 500 is fixed on the vibration output part 320, and a space is formed between the vibration table 500 and the housing 200. The workpiece bearing table 600 is fixed on the vibration table 500, and the workpiece bearing table 600 is used for placing a workpiece to be processed, such as a mobile phone glass cover plate. For example, the workpiece holder 600 may be fixed to the vibration table 500 by a fastener such as a screw. Of course, in other embodiments, the workpiece support platform 600 may be integrally formed with the vibration platform 500.
The ultrasonic vibration isolation structure is defined to include the ultrasonic reversing block 300 and the housing 200, and further, a bearing part 390 is further provided at the top of the ultrasonic reversing block 300, and the bearing part 390 is located at the periphery of the vibration output part 320. For example, the bearing part 390 may be located on the circumferential side of one end of the vibration output part 320. The housing 200 has a top plate 220 and a peripheral wall 230, the opening 201 is opened on the top plate 220, a damping arm 202 is formed on the inner side wall of the opening 201 in a protruding manner, the thickness of the damping arm 202 is smaller than that of the top plate 220, the damping arm 202 is lapped on the bearing part 390, and the vibration output part 320 protrudes out of the housing 200 through the opening 201. The top plate 220 is spaced apart from the vibration output portion 320.
When assembled, the damping arm 202 is mounted on the carrier 390, and the vibration output portion 320 protrudes out of the housing 200 through the opening 201. During operation, ultrasonic vibration is transmitted to the vibration table 500 through the vibration output part 320, and since the housing 200 is lapped on the bearing part 390 through the vibration reduction arm 202, the ultrasonic vibration of the vibration output part 320 is transmitted to the vibration reduction arm 202, and the thickness of the vibration reduction arm 202 is smaller than that of the top plate 220 of the housing 200, so that the vibration reduction arm 202 is more easily deformed than the top plate 220 of the housing 200, and the ultrasonic vibration transmitted from the vibration output part 320 is offset, so that the ultrasonic vibration transmitted from the vibration output part 320 is not or rarely transmitted to the housing 200, and the housing 200 is not influenced by the ultrasonic vibration, and the processing precision is ensured.
In addition, in the illustrated embodiment, since the vibration output portion 320 is located at the top of the ultrasonic reversing block 300 and the vibration input portion 310 is located at the bottom of the ultrasonic reversing block 300, in combination with the principle of zero point vibration, the zero point vibration is located approximately at or near the contact between the damping arm 202 and the bearing portion 390, so that the damping arm 202 is disposed on the inner side wall of the opening 201 of the housing 200, and the ultrasonic vibration received by the damping arm 202 is small or even close to the zero point, thereby being more beneficial to avoiding the transmission of the ultrasonic vibration to the housing 200.
Further, the damper arm 202 has a contact surface 203 and a welding surface 204, the damper arm 202 is contacted to the mount 390 via the contact surface 203, and the damper arm 202 is welded to the side surface of the vibration output portion 320 via the welding surface 204. Therefore, the damping arm 202 is fixed to the ultrasonic reversing block 300 by welding. For example, a half V-shaped groove may be formed in the damper arm 202, a half V-shaped groove may be formed in the vibration output portion 320, the two half V-shaped grooves may form a V-shaped groove, and then the V-shaped groove may be filled with solder to be welded, thereby improving the firmness between the damper arm 202 and the ultrasonic wave commutation block 300.
Further, a boss 205 is convexly arranged on the top surface of the vibration damping arm 202, the opening 201 penetrates 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 provision of the boss 205 not only increases the contact area between the vibration reduction arm 202 and the vibration output portion 320 to improve the firmness between the vibration reduction arm 202 and the ultrasonic wave reversing block 300, but also the top surface of the boss 205 is lower than the top surface of the vibration output portion 320, so that the boss 205 does not directly contact the vibration table 500, and the ultrasonic vibration of the vibration table 500 is prevented from being transmitted to the housing 200 through the boss 205. The length of the boss 205 may be less than the thickness of the damping arm 202.
Of course, in other embodiments, the damping arm 202 is located above the inner sidewall of the opening 201, and the top surface of the damping arm 202 is disposed flush with the top surface of the housing 200. For example, the damping arm 202 may be formed by a slot at the bottom of the top plate 220 of the housing 200, thus simplifying the molding process.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
