Abstract
Description
Die vorliegende Erfindung betrifft einen Schlüssel, insbesondere einen elektronischen Drehmomentschlüssel mit einer Auslöseeinheit.The The present invention relates to a key, in particular an electronic torque wrench with a trip unit.
Herkömmliche
Drehmomentschlüssel können in mechanische Arten,
wie zum Beispiel die in den
Bei einem herkömmlichen elektronischen Drehmomentschlüssel werden in der Regel mehrere Dehungsmessstreifen eingesetzt, die an einem Hebel angebracht sind, um einen veränderlichen Widerstand zu erzeugen und so ein angelegtes Drehmoment zu messen. Wenn das durch den Schlüssel angelegte Drehmoment einen voreingestellten Drehmomentwert überschreitet, aktiviert eine Verarbeitungseinheit des Schlüssels einen Vibrationsmotor, ein hörbares Alarmsignal oder eine aufleuchtende Lampe, um den Benutzer zu warnen. Obgleich ein herkömmlicher elektronischer Drehmomentschlüssel den voreingestellten Drehmomentwert durch ein elektronisches Steuerverfahren genau einstellen kann, kann der Benutzer das Auslösen des Hebels nicht direkt und deutlich fühlen, da der Hebel nicht so verschoben werden kann, dass er gegen das röhrenförmige Gehäuse stößt, so dass der Benutzer den Betrieb wahrscheinlich zu spät anhält, was zur Ausübung eines übermäßigen Drehmoments führt.at a conventional electronic torque wrench As a rule, several strain gauges are used, the attached to a lever to a variable To create resistance and thus to measure an applied torque. If the torque applied by the key has a preset torque value is exceeded, activated a processing unit of the key a vibration motor, an audible alarm or a flashing lamp, to warn the user. Although a conventional electronic Torque wrench the preset torque value through an electronic control method can set exactly the user can not trigger the lever directly and feel clearly, because the lever will not be moved that way that he can against the tubular case bumps, so that the user is likely to operate Too late, which leads to the exercise of excessive Torque leads.
Deshalb besteht die Aufgabe der vorliegenden Erfindung in der Bereitstellung eines elektronischen Drehmomentschlüssels, der ein genaues und direktes Auslösen ähnlich wie bei einem mechanischen Drehmomentschlüssel erzeugen kann.Therefore the object of the present invention is to provide an electronic torque wrench that is an accurate and direct release similar to a mechanical one Can generate torque wrench.
Gemäß der vorliegenden Erfindung umfasst ein elektronischer Drehmomentschlüssel ein röhrenförmiges Gehäuse, eine Arbeitseinheit, einen Dehnungssensor, eine Auslöseeinheit und einen Zentralprozessor. Das röhrenförmige Gehäuse weist eine Umgebungswand auf, die einen Aufnahmeraum mit einer Längsachse begrenzt. Die Arbeitseinheit weist einen sich von dem röhrenförmigen Gehäuse nach außen erstreckenden Antriebskopf und einen sich axial in den Aufnahmeraum erstreckenden Schaftteil auf, der an einem Drehpunkt an der Umgebungswand angelenkt ist. Der Dehnungssensor ist in der Arbeitseinheit vorgesehen. Die Auslöseeinheit weist mindestens ein angetriebenes Element auf, das im Schaftteil angeordnet ist und sich zwischen einer Nichtauslöseposition und einer Auslöseposition bewegen kann. In der Nichtauslöseposition wird das angetriebene Element dicht gegen die Umgebungswand gedrückt, so dass die Arbeitseinheit bezüglich des röhrenförmigen Gehäuses nicht schwenken kann. In der Auslöseposition wird das angetriebene Element nicht dicht gegen die Umgebungswand gedrückt, so dass die Arbeitseinheit bezüglich des röhrenförmigen Gehäuses schwenken kann. Der Zentralprozessor ist im röhrenförmigen Gehäuse vorgesehen und elektrisch mit dem Dehnungssensor und der Auslöseeinheit verbunden. Der Zentralprozessor steuert und bewegt das angetriebene Element in die Auslöseposition, wenn ein durch den Dehnungssensor gemessenes angelegtes Drehmoment größer als ein voreingestellter Bezugsdrehmomentwert ist.According to the The present invention includes an electronic torque wrench a tubular housing, a working unit, a strain sensor, a trip unit and a central processor. The tubular housing has a surrounding wall on, which limits a receiving space with a longitudinal axis. The unit of work is one of the tubular Housing outwardly extending drive head and a shaft part extending axially into the receiving space, which is articulated at a pivot point on the surrounding wall. The strain sensor is provided in the work unit. The trip unit has at least one driven element in the shaft part is arranged and between a non-triggering position and a trigger position can move. In the non-trigger position the driven element is pressed tight against the surrounding wall, so that the working unit with respect to the tubular Housing can not pan. In the trigger position the driven element is not tight against the surrounding wall pressed so that the work unit respect of the tubular housing can. The central processor is in tubular Housing provided and electrically connected to the strain sensor and the trip unit connected. The central processor controls and moves the driven element into the release position, when an applied torque measured by the strain sensor greater than a preset reference torque value is.
