Description

Zur Erzielung eines hohen Gütegrades bei der Herstellung von Knöpfen ist es notwendig, die Bohrer an ihrer Spitze und an der Versenkerschneide öfter nachzuschleifen. Um den Bohrer nicht jedesmal anschließend wieder zentrieren und einstellen zu müssen, was erfahrungsgemäß schwierig und zeitraubend ist, wurde bisher die Spindel mit dem Bohrer stillgesetzt und aus ihren Lagerstellen genommen, was naturgemäß bezüglich der Abnutzung der Lager zu großen Unzuträglichkeiten führte. To achieve a high level of quality in the manufacture of buttons it is necessary to use the drill at its tip and at the countersink more often regrind. Do not then re-center around the drill every time and to have to adjust, which experience has shown is difficult and time-consuming, has been up to now the spindle with the drill stopped and taken from its bearings, what naturally led to major inconveniences with regard to the wear and tear of the bearings.

Die Erfindung vermeidet diese Nachteile. Sie ist in den Abb. I und 2 der Zeichnung beispielsweise veranschaulicht; es stellt dar 1 Bohrspindel, 2 Spannfutter, 3 Bohrer, 4 Abdrückmutter, 5 Kugellager, 6 Führungshüchse. The invention avoids these disadvantages. It is shown in Figs. I and 2 of the drawing illustrates, for example; it represents 1 drilling spindle, 2 chucks, 3 drill bits, 4 jack nuts, 5 ball bearings, 6 guide sleeves.

Die Spindel I weist in ihrem unteren Ende einen Kegelscllaft auf, in den das Spannfutter 2 mit haftendem Sitz, genau zentriert, paßt. Das Lösen des Futters zum Zwecke des Bohrerschleifens geschieht durch Abdrücken mittels der Mutter 4; dazu ist auf die Spindel über ihrem Kegelende ein Gewinde aufgeschnitten. Somit ist es möglich, den Bohrer zu schleifen, ohne ihn auszuspannen bzw. ohne die ganze Spindel herausnehmen zu miissen. The spindle I has a conical shape in its lower end, in which the chuck 2 with adhesive seat, exactly centered, fits. Solving the Chuck for the purpose of drill grinding is done by pressing the nut 4; for this purpose, a thread is cut on the spindle above its cone end. Consequently it is possible to grind the drill without unclamping it or without the whole To have to take out the spindle.
