In one embodiment, as shown in fig. 10, the first base vibration isolation groove 431 is ring-shaped, and the second base vibration isolation groove 432 is ring-shaped.
Because the first base vibration isolation groove 431 and the second base vibration isolation groove 432 are annular, the base vibration transmission area 41 and the base vibration isolation area 42 are isolated, the transmission of the vibration energy of the base vibration transmission area 41 to the base vibration isolation area 42 is reduced, and better vibration and noise reduction effects can be realized.
In the embodiment shown in fig. 10, the first base vibration isolation groove 431 and the second base vibration isolation groove 432 are both in the shape of a rectangular ring, which is the same as the outer circumference of the base 4.
In an embodiment not shown in the figures, the base isolation structure may further comprise other numbers of base isolation grooves, such as 1, 3, 5, etc. When the base vibration isolation structure includes a plurality of base vibration isolation grooves, the plurality of base vibration isolation grooves may be simultaneously located on the same surface (upper surface or lower surface) of the base, or may be partially located on the upper surface of the base and partially located on the lower surface of the base.
In one embodiment, as shown in fig. 7, the lower surface of the lower shell 22 protrudes downward to form a bump 23, and the bump 23 is fixedly connected to the base vibration transmission region 41.
The contact vibration transmission area of the lower shell 22 and the base 4 is reduced by providing the projection 23 on the lower surface of the lower shell 22.
In the embodiment shown in fig. 7, the lower bottom surface of the lower shell 22 has 4 bumps 23.
In other embodiments not shown in the drawings, the number of the bumps may also be 3, 5 or 6, and the number and arrangement of the bumps are required to ensure that the lower shell can be smoothly installed on the vibration transmission region of the base.
In one embodiment, as shown in fig. 6 and 7, the lower shell 22 is provided with cable holes 24 for passing cables.
The cable hole 24 is internally provided with a cable, the ultrasonic generator 3 is connected with external equipment through the cable so as to receive a high-frequency excitation signal from the external equipment, the ultrasonic generator 3 converts the received high-frequency excitation signal into high-frequency mechanical vibration and excites the vibration plate 1 of the ultrasonic vibration device to vibrate, so that the whole workpiece to be machined is driven to vibrate at high frequency.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
