Abstract
A simple ultrasonic tool head comprises an ultrasonic tool head body and a hemispherical head, wherein the surface of the ultrasonic tool head body is smooth and columnar, a mounting hole is formed in the tail end of the ultrasonic tool head body, and a threaded hole is formed in the head end of the ultrasonic tool head body; the hemispherical head comprises a circular plane end and a hemispherical surface end, and the circular plane end is connected with a threaded rod matched with the threaded hole; when the threaded rod of the hemispherical head is arranged in the threaded hole, the ultrasonic tool head body and the hemispherical head form the ultrasonic tool head. The end part which is easy to wear is arranged at the end part of the ultrasonic tool head in a detachable connection mode.
Description
Technical Field
The utility model relates to the technical field of generation or transmission of mechanical vibration, in particular to an ultrasonic tool head for transmitting ultrasonic vibration.
Background
The function of the ultrasonic transducer is to convert the input electric power into mechanical power (i.e. ultrasonic waves) and transmit the mechanical power, and a small part of the power is consumed by the ultrasonic transducer. Ultrasonic tool heads are important components of ultrasonic devices, and have the function of transmitting the vibration energy of ultrasonic waves into an object of action. The ultrasonic tool head is generally in the shape of a cylinder, a cone, a cuboid and the like, the working surface of the ultrasonic tool head is basically the end surface of the top end, and the working surface of the ultrasonic tool head is generally not large in consideration of actual installation and use, so that the radiation capacity is relatively concentrated, and the ultrasonic tool head can be better applied to the traditional ultrasonic application directions of ultrasonic welding, cutting and the like.
The power density of the end of the ultrasonic tool head is the largest, the energy is most concentrated, and the end of the ultrasonic tool head is partially cavitated, abraded and more severely cavitated during the working process.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art, and provides a simple ultrasonic tool head, wherein the end part which is easy to wear is arranged at the end part of the ultrasonic tool head in a detachable connection mode, and the ultrasonic tool head is in a split type design, is convenient to replace and use.
The technical scheme of the utility model is as follows: the ultrasonic tool head comprises an ultrasonic tool head body and a hemispherical head, wherein the surface of the ultrasonic tool head body is smooth and columnar, a mounting hole is formed in the tail end of the ultrasonic tool head body, and a threaded hole is formed in the head end of the ultrasonic tool head body; the hemispherical head comprises a circular plane end and a hemispherical surface end, and the circular plane end is connected with a threaded rod matched with the threaded hole; when the threaded rod of the hemispherical head is arranged in the threaded hole, the ultrasonic tool head body and the hemispherical head form the ultrasonic tool head.
And a flange sheet is mounted at a zero node of the ultrasonic tool head body and is close to the head end of the ultrasonic tool head body. The zero node position needs to be determined according to the frequency, the wavelength and the design structure of the tool head, the maximum amplitude position and the zero amplitude position exist in one wavelength, the zero node wafer is arranged at the zero amplitude position, and the zero amplitude position can be regarded as zero vibration without doing work and consuming energy when the transducer works.
The threaded rod is arranged at the position of the center of the circle of the circular plane end.
The ultrasonic tool head body is made of a round steel pipe or a round steel rod.
The diameter of the circular plane end is the same as the diameter of the ultrasonic tool head body.
The ultrasonic energy radiation surface is the whole tool head, and the radiation area is wider; the processing is convenient and the time is saved; long service life and material saving. Aiming at the fact that cavitation, abrasion and cavitation of the head end part of the ultrasonic tool are severe mainly in the working process, the utility model adopts a split type design, and is convenient for replacing the hemispherical head part.
