Abstract
The utility model relates to an ultrasonic tool head. An installation hole is formed in the tool head, wherein the installation hole is used for connecting an ultrasonic transducer or an installation hole of an amplitude-change pole. The ultrasonic tool head is an ultrasonic radiation head in an annular-body shape or the shape of the ultrasonic radiation head is similar to the annular-body shape. The ultrasonic tool head is provided with at least a first annular curved surface which radiates ultrasonic waves in a bending vibration mode. According to the ultrasonic tool head, the radiation curved surface with the curvature replaces a single plane radiation surface, and therefore the radiating area of the tool head is greatly increased. In addition, due to the fact that radial radiation similar to annular-shape radiation is applied to the tool head which is in an annular-body shape or similar to the annular-body shape, sound filed evenness in liquid or in gas is better. Besides, due to the fact that the bending vibration mode is applied to the radiating curved surface, the direction of transmission of the vibration is changed, the sound intensity of radiation is more uniform, and the flexibility of utilization of the tool head is improved. Therefore, the ultrasonic tool head can be appropriate for some ultrasonic welding connections and serves as the amplitude-change pole, wherein the sections of the ultrasonic welding connections are similar to circular surfaces.
