Abstract

The invention relates to an ultrasonic tool head. The ultrasonic tool head is provided with an installation hole which is used for connecting an ultrasonic transducer or an amplitude amplifier pole, the ultrasonic tool head is an ultrasonic radiation head which is of a circular ring body shape or is similar to the circular body shape, and the ultrasonic tool head at least is provided with one first circular ring curved surface which is used for radiating ultrasonic waves by adopting a bending vibration way. According to the ultrasonic tool head disclosed by the invention, a single flat-surface radiation surface is replaced by utilizing a radiation curved surface with the curvature, and thus the radiation area of the ultrasonic tool head is greatly increased; meanwhile, the radiation surface of the ultrasonic tool head, which is of a circular ring shape or similar to the circular ring shape, adopts radial radiation which is similar to the circular ring shape, and thus the uniformity of a sound field in liquid or gas is better; and the radiation curved surface adopts the bending vibration way, thus the transmission direction of vibration is changed, the radiation sound intensity is more uniform, the using flexibility of the ultrasonic tool head is increased, and the ultrasonic tool head is suitable for the welding of the ultrasonic waves of which the cross sections are similar to round surfaces and can be used as the amplitude amplifier pole.

Description

technical field

[0001] The invention relates to the technical field of generation or transmission of mechanical vibrations, in particular to an ultrasonic tool head for ultrasonic vibration transmission. Background technique

[0002] Ultrasonic tool head is an important component of ultrasonic equipment, and its function is to transmit ultrasonic vibration energy to the target. The shape of the ultrasonic tool head is generally a cylinder, a cone or a cuboid, and its working surface is basically the end surface of the top. Considering the actual installation and use, the working surface of this type of tool head is generally small, so the radiation ability is relatively large. It is more concentrated and can be better applied in the traditional application directions of ultrasonic waves such as ultrasonic welding and cutting. However, with the continuous advancement of science and technology, ultrasonic waves are no longer limited to traditional applications, and their appl...
