Abstract
Die Erfindung betrifft eine Vorrichtung zum Schleifen der Schneiden von Bohrern in Verbindung mit einem Schleif scheibenantrieb bestehend aus einer Einspanneinrichtung für den zu schleifenden Bohrer in Form von zwei als Einheit verbundene Spannbacken zum Zwischenspannen dessel ben, welche Spannbacken auf einem Bolzen am Standteil umsteckbar angeordnet sind. Hierbei ist es Aufgabe der Erfindung eine Haltevorrichtung für handwerkliche und maschinelle Zwecke zu schaffen, welche mit größeren Bohrern mit 20, 40, 60 mm und mehr Durchmesser arbeiten. Die Vorrichtung zeichnet sich hierfür durch einen L-förmigen Aufnahmeteil für die Spannbackeneinheit aus, wobei der Bozen zum festen Aufstecken derselben am Basisteil der Aufnahme nach oben steht, während der Rückenteil der Aufnahme am Standteil schwenkbar gelagert ist mit waage rechter und zum Steckbolzen rechtwinkliger Lagerachse, derart, daß bei eingespanntem Bohrer dessen Schneidkegel von der Lagerachse um diese schwenkbar durchkreuzt wird. The invention relates to a device for grinding the Cutting drills in connection with a grinding disc drive consisting of a clamping device for the drill to be ground in the form of two as a unit connected jaws for intermediate clamping of the same ben, which jaws on a bolt on the stand part are arranged reversible. It is the job of Invention a holding device for craft and to create mechanical purposes, which with larger Work drills with 20, 40, 60 mm and more diameters. For this purpose, the device is characterized by an L-shaped one Receiving part for the jaw unit, the Bolzano for firmly attaching them to the base part of the Recording is up while the back of the The receptacle on the stand is pivoted with a scale right and right-angled bearing axis to the pin, such that when the drill is clamped, its cutting cone is crossed by the bearing axis pivotable about this.
