Description
Die Erfindung bezieht sich auf einen Senker mit ausschwingendem Messer. Er ermöglicht, einfach und schnell innenliegende Bohrungen anzusenken. Inniensenker mit ausschwingenden Messern sind zwar schon länger bekannt, doch müssen alle durch besonders angebrachte und durchweg verwickelte Vorrichtungen gesteuert werden.The invention relates to a countersink with a swinging knife. He enables countersink internal bores quickly and easily. Inner countersink with swinging out Knives have been known for a long time, but all have to be made by specially attached and consistently intricate devices being controlled.
Die Arbeitsweise dieser schon bekannten to Innensenker ist daher oft unwirtschaftlich. Durch die selbsttätige Einstellung des Messers am Erfindungsgegenstand geht das Ansenken ininen fast so schnell als außen, denn die Drehbewegung der Arbeitsspindel braucht wie bei einem gewöhnlichen Außensenker nicht unterbrochen zu werden.The working method of this already known to countersink is therefore often uneconomical. Countersinking occurs through the automatic adjustment of the knife on the subject of the invention inside almost as fast as outside, because the work spindle needs the rotary movement not to be interrupted as with an ordinary countersink.
Bei den Innensenkern mit gesteuerten Messern ist ferner der Winkel der Ansenkung der Größe des Spanvorschubs entsprechend veränderlich, jedoch beim Erfindungsgegenstand immer gleich und unabhängig von der Größe der Spanabhebung.In the case of the inner countersink with controlled knives, the angle of the countersink is also the The size of the chip feed can be changed accordingly, but with the subject matter of the invention always the same and independent of the size of the chip removal.
Eine Ausführungsform des Erfindungsgegenstandes ist auf der Zeichnung beispielsweise dargestellt. Es zeigt:An embodiment of the subject matter of the invention is shown in the drawing, for example shown. It shows:

Abb. 5 die Arbeitsstellung des Messers.
Der Senker besteht aus drei Teilen, dem Schaft«, dem Messer δ und dem Bolzene.
Beim Ansenken großer Bohrungen kann der Schaft« auch kegelig gestaltet werden.Fig. 5 the working position of the knife.
The countersink consists of three parts, the shaft «, the knife δ and the bolt. When countersinking large bores, the shank can also be designed with a taper.
Der Schaft« ist unten als gegabelter Halter ausgebildet, in dem das Messer b leicht beweglich am Bolzene angeordnet ist. Das Messer b ist auswechselbar. Durch die Aussparung d wird die Lage, des Messers bestimmt, die durch die Schwerpunktverlagerung desselben herbeigeführt wird.The shaft ″ is designed as a forked holder at the bottom, in which the knife b is arranged on the bolt so that it can move easily. The knife b is exchangeable. The position of the knife, which is brought about by the shift in its center of gravity, is determined by the recess d.
Vor Beginn der Arbeit nimmt das Messer b immer die steile Lage gernjiß Abb. 1 ein. Für das Ansenken wird die Arbeitsspindel zunächst in Drehbewegung gebracht und dann der Senker durch axialen Vorschub der Arbeitsspindel frei durch die Bohrung geführt. Das Werkstück wird dann seitlich etwas verschoben, so daß sich die Kanten des Messers auf die Arbeitsfläche aufsetzt. Durch weiteren Vorschub der Arbeitsspindel wird das Messer in die richtige Arbeitsstellung gebracht. Ist die Spanabhebung am Werkstück beendet, wird die Arbeitsspindel zurückbewegt. Sofort nimmt das Messer selbstfetig wieder f die Steillage ein und kann bequem aus der Bohrung zurückgeführt werden.Before starting work, the knife b always assumes the steep position, as shown in Fig. 1. For countersinking, the work spindle is first made to rotate and then the countersink is guided freely through the bore by axially advancing the work spindle. The workpiece is then shifted a little sideways so that the edges of the knife touch the work surface. By advancing the work spindle further, the knife is brought into the correct working position. When the chip removal on the workpiece is finished, the work spindle is moved back. Immediately takes the knife selbstfetig again f is the forward position, and can be easily recycled from the bore.
