Description
Die Erfindung betrifft einen Drehmomentschlüssel mit Auslösemechanismus von der im Oberbegriff des Anspruchs 1 angegebenen Art.The The invention relates to a torque wrench with a triggering mechanism of the type specified in the preamble of claim 1.
Solche sogenannte auslösende Drehmomentschlüssel werden in der Serienmontage (z. B. Automobilindustrie) sowie in der Einzelmontage (Werkstätten, Maschinenbau) verwendet, um sicherzustellen oder zu überprüfen, dass die Schraubverbindungen auf ein jeweils vorgegebenes Mindestdrehmoment festgezogen werden. Die bei Erreichen des Drehmoments erfolgende Auslösung wird vom Benutzer mit der Hand erfühlt und/oder durch ein dabei auftretendes typisches Klickgeräusch wahrgenommen. Zusätzlich kann bei der Auslösung ein Kontrollsignal erzeugt und an eine externe Empfangseinrichtung übertragen werden, die anhand der empfangenen Signale prüft und dokumentiert, ob sämtliche bei einem Werkstück festzuziehenden Schraubverbindungen ordnungsgemäß auf das Mindestdrehmoment festgezogen worden sind.Such so-called triggering torque wrench are used in series assembly (eg automotive industry) as well as in individual assembly (workshops, Mechanical Engineering) used to ensure or verify that the screw connections to a given minimum torque be tightened. The taking place when the torque is reached release is felt by the user by hand and / or by one occurring typical click sound perceived. additionally can when triggered generates a control signal and transmitted to an external receiving device which checks and documents on the basis of the received signals, whether all at a workpiece tightened screw properly to the minimum torque have been tightened.
Der Auslösewiderstand, bei dessen Überwindung die Auslösung erfolgt, kann mittels einer Einstellvorrichtung so eingestellt werden, dass er einem gewünschten Anziehdrehmoment entspricht. Die in der Serienmontage verwendeten Drehmomentschlüssel werden vorweg auf einen bestimmten Drehmomentwert eingestellt und dann durchgehend mit dieser Einstellung verwendet. In der Einzelmontage muss der Benutzer die Einstellung oft verändern, um Schraubverbindungen mit unterschiedlichen Drehmomenten festziehen zu können. Dabei besteht jedoch die Problematik, dass nicht ausgeschlossen werden kann, dass der Drehmomentschlüssel mit einem falsch eingestellten Auslösewiderstand verwendet wird. In der Serienmontage kann es vorkommen, dass der Werker die Einstellung des Drehmomentschlüssel eigenmächtig verändert oder unterschiedlich eingestellte Drehmomentschlüssel miteinander verwechselt. Bei der Einzelmontage ist das Problem der richtigen Einstellung des Drehmomentschlüssels noch kritischer, da der Werker selbst die Einstellungen vornehmen muss und dabei Fehler machen kann.Of the Trip resistance, in overcoming it the trigger can be adjusted by means of a setting device, that he wanted Tightening torque corresponds. The used in the series assembly torque wrench are set in advance to a certain torque value and then used throughout with this setting. In the single assembly The user often has to change the setting to screw connections tighten with different torques. there However, there is the problem that can not be excluded can that the torque wrench is used with an incorrectly set trip resistance. In the series assembly, it may happen that the worker the setting of the torque wrench unauthorized changed or different set torque wrench confused with each other. For single mounting, the problem is the right attitude of the torque wrench yet more critical, since the worker himself must make the settings and can make mistakes.
Aus
Der Erfindung liegt die Aufgabe zugrunde, einen Drehmomentschlüssel der angegebenen Art dahingehend zu verbessern, dass bei jedem Auslösevorgang gleichzeitig eine Kontrolle über die richtige Einstellung des Drehmomentschlüssels ermöglicht wird.Of the Invention is the object of a torque wrench of specified type to improve that at each triggering operation at the same time a control over the correct setting of the torque wrench is made possible.
Die erfindungsgemäße Lösung der Aufgabe ist in den Patentansprüchen angegeben.The inventive solution of Task is in the claims specified.
Durch die Erfassung der Einstellposition der Einstellvorrichtung und die Übertragung eines entsprechenden Signals an die externe Empfangsvorrichtung bei jedem Auslösevorgang wird es der externen Empfangsvorrichtung ermöglicht, zu prüfen und zu dokumentieren, ob sämtliche für den jeweiligen Montagevorgang erforderlichen Schraubverbindungen mit einer ”richtigen” Einstellung des Drehmomentschlüssels festgezogen worden sind, d. h. mit einer Einstellung des Auslösedrehmoments, die dem vorgeschriebenen Mindestdrehmoment entspricht.By the detection of the setting position of the adjuster and the transmission a corresponding signal to the external receiving device at every triggering process It will enable the external receiving device to test and to document whether all for the each assembly process required screw with a "right" attitude of the torque wrench have been tightened, d. H. with a setting of the triggering torque, which corresponds to the prescribed minimum torque.
Eine Ausführungsform der Erfindung wird anhand der Zeichnung näher erläutert. Diese zeigt eine schematische Draufsicht eines erfindungsgemäßen Drehmomentschlüssels, wobei die elektrischen bzw. elektronischen Komponenten vereinfacht als Blockschaltbild dargestellt sind.A embodiment The invention will be explained in more detail with reference to the drawing. This shows a schematic Top view of a torque wrench according to the invention, wherein the electrical or electronic components simplified as a block diagram are shown.
