Abstract

To assist their actual function, manually or mechanically actuated tools are set in ultrasonic vibration at the tool tip in such a way that the tools are given a widened range of use. For example, jammed or rusted-in screws can be unscrewed with the ultrasonic tool without resulting in a tool or screw fracture.

Description

Anwendungsgebiet:Field of use:

Die Erfindung betrifft manuell oder maschinell betätigte Werkzeuge,die zur Unterstützung der eigentlichen Funktion derart in Ultraschallschwingungen versetzt werden, daß die Werkzeuge einen erweiterten Anwendungsbereich bekommen.The invention relates to manually or mechanically operated tools that to support the actual function in such a way set in ultrasonic vibrations that the tools get a wider area of application.

Stand der Technik: Werkzeuge, wie z.B. Schraubendreher, Maulschlüssel, können Schrauben bis zu einer bestimmten Drehmomentgrenze einschrauben, anschließend bricht entueder die Schraube aufgrund der zu großen Reibungskräfte im Gewinde oder das Werkzeug verformt sich bzw. wird zerstört.Genauso kann das Aufdrehen festsitzender bzw. festgerosteter Schrauben zum Zerstören oder Verformen des Werkzeuges führen, wenn die Schrauben nicht über mehrere Stunden vorher mit einem rostlösenden 01 oder ähnlichem behandelt wurden und erhöhte Kräfte deshalb erforderlich sind. Abgebrochene Schrauben müssen aus dem Werkstück ausgebohrt werden, eventuell ist das Gewinde beschädigt, so daß ein neues Gewinde mit größerem Durchmesser ins Werkstück geschnitten werden muß oder ein Gewindeeinsatz erforderlich wird.State of the art: tools such as screwdrivers, open-end wrenches, can screw in screws up to a certain torque limit, then Either the screw breaks due to excessive friction in the thread or the tool deforms or is destroyed or rusted screws lead to the destruction or deformation of the tool, if the screws have not been treated with a rust-removing 01 or were treated similarly and therefore increased forces are required. Aborted Screws must be drilled out of the workpiece, possibly the thread damaged, so that a new thread with a larger diameter is cut into the workpiece or a threaded insert is required.

Bohren in Werkstücke mit hoher Härte führt meist zu übergroßer Bohrerhitze, vorzeitigem Stumpfwerden der Bohrerspitze und Bohrerbruch können die Folge sein Das Ein- oder Austreiben von Stiften kann ebenfalls unter Umständen eine überhöhte Kraft erforderlich machen, für die das Werkzeug nicht ausgelegt ist.Drilling in workpieces with high hardness usually leads to excessive drill heat, The result can be premature blunting of the drill tip and drill breakage Driving in or out of pins can also be excessive Require force for which the tool is not designed.

Aufgabe: Der Erfindung liegen die Aufgaben zugrunde, ein Lösen festsitzender Schrauben über ein in Ultraschallschwingungen versetztes Werkzeug zu erreichen. Genauso sollen die Ultraschallschwingungen den Eindrehvorgang einer Schraube erleichtern, in dem durch die Ultraschallschwingungen die Reibung zwischen Schraube und Werkstückgewinde verringert wird.Task: The invention is based on the task of releasing stuck To achieve screws using a tool set in ultrasonic vibrations. In the same way, the ultrasonic vibrations should facilitate the screwing-in process of a screw, in which the friction between the screw and the workpiece thread is caused by the ultrasonic vibrations is decreased.

Genau das Gleiche gilt für das Eintreiben bzw. Ausschlagen von Stiften in bzw. aus einem Werkstück.Exactly the same applies to driving in or knocking out pins in or out of a workpiece.

Die Unfallgefahren werden verringert, wenn am Werkzeug dank der Ultraschallunterstützung keine derartig hohen Kräfte, die zum Werkstück-oder Werkzeugbruch führen können, auf treten.The risk of accidents is reduced when on the tool thanks to the ultrasonic support no such high forces that can lead to workpiece or tool breakage, appear.

Ausführung: Das Werkzeug wird mit einem Mechanismus versehen, der die Werkzeugspitze in Ultraschallschwingungen (20.0nu ...60.000 Hz, Amplitude 0,005...0,1 mm) versetzt. Dieser Mechanismus kann in das Werkzeug integriert sein oder an das Werkzeug angekoppelt werden, ohne daß die eigentliche Werkzeughandhabung dadurch erschwert wird. Die Ultraschallquelle (z.B. ein Nickel-Lamellenbündel, das über einen hochfrequenten Strom in Schwingungen gebracht wird) wird als Energiezufuhr vorzugsweise mit elektrischem Strom gespeist. Die Werkzeuge werden -sofern nicht schon vorhanden- mit einer Netzleitung bzw. Energieleitung versehen.Execution: The tool is provided with a mechanism that the tool tip in ultrasonic vibrations (20.0nu ... 60,000 Hz, amplitude 0.005 ... 0.1 mm) offset. This mechanism can be integrated into the tool or attached to the Tool can be coupled without the actual tool handling thereby is made more difficult. The ultrasound source (e.g. a bundle of nickel lamellas that extends over a high-frequency current is made to vibrate) is used as an energy supply preferably fed with electricity. The tools are - so far not already available - provided with a power line or power line.
