Description
Technisches Gebiettechnical area
Die Erfindung betrifft die Meßeinrichtung eines Handwerkzeuges, die eine höhere Meßgenauigkeit aufweist.The The invention relates to the measuring device of a hand tool, a higher one measurement accuracy having.
Stand der TechnikState of technology
Bei einem Drehmomentwerkzeug wird das Werkstück durch das Drehmoment festgezogen oder abgedreht. Wenn das Drehmoment zu groß ist, kann das Werkzeug übertrieben festgezogen werden, was zu einem Bruch oder einer Verformung des Werkstückes führen kann. Wenn das Drehmoment zu klein ist, kann das Werkzeug unzureichend festgezogen werden, was zu einem Herunterfallen des Werkstückes führen kann. Aus dem amerikanischen Patent 3970155 ist ein Schraubenschlüssel bekannt, der zwischen dem Handgriff und dem Kopf zwei Spannungsmesser aufweist, der mit einem Auswerter und einem Display des Handgriffs verbunden ist. Diese Spannungsmesser sind nicht direkt am Ort des Drehmomentes angeordnet, so daß die Meßgenauigkeit niedrig ist.at a torque tool, the workpiece is tightened by the torque or turned off. If the torque is too high, the tool may be exaggerated be tightened, resulting in a fracture or deformation of the workpiece to lead can. If the torque is too small, the tool may be insufficient be tightened, which can lead to a fall of the workpiece. From the American patent 3970155 a wrench is known, which between the handle and the head has two voltmeter, the with an evaluator and a display of the handle is connected. These voltmeters are not directly at the location of the torque arranged so that the Measurement accuracy low is.
Aufgabe der ErfindungTask of invention
Der Erfindung liegt die Aufgabe zugrunde, die Meßeinrichtung eines Handwerkzeuges zu schaffen, die eine höhere Meßgenauigkeit aufweist.Of the Invention is based on the object, the measuring device of a hand tool to create a higher one measurement accuracy having.
Diese Aufgabe wird durch die erfindungsgemäße Meßeinrichtung eines Handwerkzeuges gelöst, die in den inneren Seitenwänden des Kopfs mindestens einen Sensor aufweist, der mit einem Prozessor verbunden ist, wobei, wenn der Kopf ein Werkstück dreht, der Sensor mit einer Gegenkraft aus dem Werkstück belastet wird und somit ein Signal erzeugt, das an den Prozessor gesendet wird, der entsprechend dem Signal einen Drehmomentwert errechnet und diesen auf einem Display anzeigt.These The object is achieved by the measuring device according to the invention of a hand tool solved, in the inner sidewalls of the head has at least one sensor connected to a processor is connected, wherein when the head rotates a workpiece, the sensor with a Counterforce from the workpiece is loaded and thus generates a signal to the processor is sent, which according to the signal a torque value calculated and displays this on a display.
Da der Sensor im Kopf angeordnet ist, wird der Sensor direkt mit der Druckkraft belastet, so daß die Meßgenauigkeit höher ist.There the sensor is placed in the head, the sensor is directly connected to the Pressure loaded, so that the measurement accuracy is higher.
