摘要： The present invention concerns an ultrasonic welding installation comprising an ultrasonic vibration unit having a sonotrode and a converter, wherein the sonotrode and the converter are arranged in mutually adjacent relationship along a longitudinal axis and the ultrasonic vibration unit can be caused to resonate with an ultrasonic vibration in the direction of the longitudinal axis with a wavelength λ, wherein there can be provided an amplitude transformer arranged between the sonotrode and the converter, wherein there is provided a holder for holding the ultrasonic vibration unit. To provide an ultrasonic welding installation having a holder which allows simple adjustment of the ultrasonic vibration unit and simple replacement thereof it is proposed according to the invention that the holder has a clamping device which is reciprocable between an opened position in which the ultrasonic vibration unit can be removed from the holder and a closed position in which the clamping device comes into contact with the ultrasonic vibration unit and exerts a force on same so that the ultrasonic vibration unit is held.

摘要： The present invention concerns a vibration element like for example a sonotrode with a component fixed thereto. To provide a vibration element having a component fixed thereto, which is simple to manufacture, has a long service life and in addition prevents detachment of the component from the sonotrode, it is proposed according to the invention that the vibration element has a bore and the component has a fixing portion fitted in the bore, wherein arranged between the fixing portion and the bore is an elastic element which is either elastically deformed, and more specifically preferably parallel to the bore axis, or is arranged at least partially within a recess provided in the inside surface of the bore in such a way that the component can be removed from the bore only by elastic deformation of the elastic element.
