Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] A first aspect of the present invention provides an ultrasonic device. In an application scenario, the ultrasonic device can be installed and fixed in production equipment so that the ultrasonic device of the production equipment can perform ultrasonic processing on a workpiece to be processed at a predetermined position. The ultrasonic processing can specifically include but is not limited to scenarios such as ultrasonic welding, ultrasonic cleaning, or ultrasonic chemical processing, which are not limited here.

[0041] An ultrasonic device of the present invention, in one embodiment, Figure 1-Figure 3As shown, the ultrasonic device includes a transformer 1, a node adjustment ring 2 and a locking nut 3; wherein, the outer surface of the transformer 1 is provided with a node adjustment interval for adjusting the node position of the transformer 1. It can be understood that in the mass production process of the transformer 1, due to many factors such as the material difference of the transformer 1, the dimensional deviation of the manufacturing or the system matching, the node position of the transformer 1 will have a large change relative to the design value. Therefore, different transformers 1 can be measured by, for example, an amplitude measuring device to measure the specific node positions of different transformers 1 in the working state, or the node position of the transformer 1 in the working state can be detected by, for example, a contact method (for example, the radial amplitude is the largest at the position where the axial position is zero, etc., so that the node position can be accurately found). In this way, the measured node The point position is taken as the target node position. It can be understood that the axial amplitude of the horn 1 is the smallest in the target node position, so the energy leakage is the smallest, so that the horn 1 is fixedly installed on the main frame according to the target node position (not shown in the figure); specifically, after determining the specific target node position, the node adjustment ring 2 can be sleeved on the target node position of the node adjustment interval, wherein the node adjustment ring 2 is also provided with a plurality of connection holes 21, and the plurality of connection holes 21 can be used to install the node adjustment ring 2 on the main frame. In specific implementation, the main frame is also provided with connection holes 21 corresponding to the plurality of connection holes 21, and the connection holes 21 on the node adjustment ring 2 and the plurality of connection holes 21 on the main frame can be connected by means such as bolts, so that the ultrasonic device is installed on the main frame. It can be understood that the main frame here can be, for example, the main frame of a production equipment or a production machine, and the main frame can be used to place the ultrasonic device at a certain spatial position, so that the ultrasonic device performs ultrasonic processing on the workpiece to be processed on the fixture at the predetermined position. The locking nut 3 is sleeved on the node adjustment interval and on the top of the node adjustment ring 2 . The locking nut 3 can be used to fix the node adjustment ring 2 .

As a result, when the amplitude transformer 1 is fixedly installed on the main frame, the vibration isolation effect of the amplitude transformer can be improved, the loss of vibration energy can be reduced, and the working efficiency of the amplitude transformer can be improved. In addition, in view of the poor vibration isolation effect of the amplitude transformer, the vibration during the working process will also be transmitted to the components connected thereto. In the above-mentioned embodiment, by adjusting the nodes for different amplitude transformers 1, it is also possible to reduce damage to other components and reduce adverse effects such as heating and abnormal noise, thereby improving the stability of the ultrasonic device.

In this embodiment, by setting the internal and external threads, when the node adjustment ring 2 is sleeved on the pre-measured target node position, and then the locking nut 3 is rotated and sleeved on the upper part of the node adjustment ring 2, the locking nut 3 can have a fixing effect on the node adjustment ring 2.

[0047] Furthermore, in order to better achieve the locking effect of the locking nut 3 on the node adjustment ring 2, in one embodiment, an anti-skid structure is also provided on the annular boss 31.
