Description

Spiralbohrer wurden bisher aus den Spindeln der Bohrmaschinen mittels sogenannter Keiltreiber entfernt, deren Nachteile bekannt sind. Man hat daher schon früher Vorrichtungen angewendet, um den Bohrer durch Gegenpressen von Muttern gegen den Ansatz des Bohrers stoßlos aus der Maschine zu entfernen. Diese Vorrichtungen haben den Nachteil, daß: das Widerlager auf demTwist drills were previously made from the spindles of the drilling machines by means of so-called Removed wedge drivers whose disadvantages are known. Devices have therefore been used earlier to the drill by pressing nuts against the shoulder of the drill smoothly out of the machine to remove. These devices have the disadvantage that: the abutment on the

ίο Bohrerschaft vor seiner Einführung in die Maschine befestigt werden muß.ίο drill shank prior to its introduction to the Machine must be attached.

Die Erfindung beseitigt diese Nachteile in höchst einfacher Weise durch die Anwendung eines aus zwei gelenkig miteinander verbundenen Teilen bestehenden ringartigen Stückes, das zu einer dem Arbeiter genehmen Zeit entweder auf den bei jedem Spiralbohrer vorhandenen zylindrischen Ansatz oder auch auf den Konusschaft aufgesetzt werden kann.The invention overcomes these disadvantages in a very simple manner through use a ring-like piece consisting of two parts that are articulated to one another and which can be convenient for the worker Time either on the cylindrical attachment present in every twist drill or also can be placed on the cone shaft.

ao Durch Zwischenschieben eines Hebels, durch Dazwischenschlagen eines zweiteiligen Keiles oder schließlich durch Gegendrücken einer Mutter gegen dieses Stück kann der Bohrer mühelos entfernt werden. In den Abbildungen sind verschiedene Ausführungsbeispiele dargestellt.ao By pushing a lever in between, by slamming a two-part wedge or finally by pressing a nut against this piece, the drill can can be easily removed. The figures show various exemplary embodiments shown.

ι ist das aus zwei Teilen bestehende Stück, das entweder auf den zylindrischen Ansatz oder auf den Konusschaft des Bohrers aufgesetzt wird. Die beiden Teile sind um einen Bolzen 2 drehbar und nach Abb. 3 kegelförmg abgedreht. Soll der Spiralbohrer entfernt werden, so wird zunächst Teil 1 auseinandergeklappt und um den Spiralbohrer gelegt, so wie es im Grundriß der Abb. 1 dargestellt ist. Der Bohrer kann nun auf verschiedene Weise entfernt werden. Entweder der Hebel 3 wird zwischen Metallstück 1 und Bohrspindel 4 eingeschoben. Der Hebel 3 zeigt die gleiche Abschrägung wie das Metallstück ι (s. Abb. 3). Bei Überschieben des Hebels über das Metallstück 1 wird also verhindert, daß dieses letztere sich wider Willen auseinanderspreizen kann. Wird nun derι is the two-part piece that either attaches to the cylindrical neck or is placed on the tapered shank of the drill. The two parts can be rotated around a bolt 2 and as shown in Fig. 3 turned off in a conical shape. If the drill bit is to be removed, part 1 is unfolded first and placed around the twist drill, as shown in the plan of Fig. 1 is. The drill can now be removed in a number of ways. Either the lever 3 is between the metal piece 1 and Drilling spindle 4 pushed in. The lever 3 shows the same bevel as the metal piece ι (see Fig. 3). When the lever is pushed over the metal piece 1, this prevents that this latter can spread itself apart against its will. Will now be the

Statt des Hebels 3 'kann "rttaii "äucn'-den Doppelschlagkeil nach Abb. 5 benutzen, der aus zwei keilförmigen Hämmern 5 besteht, die an ganz leicht drehbaren Gelenken 6 befestigt sindy Die Keilhämmer werden auseinandergezogen, in den Zwischenraum zwischen Metallstück 1 und Bohrspindel 4 eingefügt und izusammengeschlagen. Dabei legen sie sich mit solchem Druck gegen das Metallstück 1 und die Bohrspindel an, daß der Bohrer leicht entfernt werden kann. Als drittes Ausführungsbeispiel für die Entfernung des Bohrers zeigt Abb. 7 eine auf die Bohrmaschinenspindel aufgeschraubte Mutter 7, die sich beim Herausdrehen aus dem Gewinde gegen das Metallstück ι legt. Abb. 8 stellt eine andere Ausführung des zweiteiligen Metallstückes 1 dar. Sie unterscheidet sich von der in Abb. 1 dargestellten nur durch die Hinzufügung eines Bolzens 8, der das nicht gewollte Auseinandergehen der beiden Teile des Metallstückes ι verhindert.Lever 3 raised, the drill is lifted with it easy to remove. Instead of the lever 3 ', "rttaii" can äucn'-the double hammer use according to Fig. 5, which consists of two wedge-shaped hammers 5, which at all easily rotatable joints 6 are attached y The wedge hammers are pulled apart, inserted into the space between the metal piece 1 and the drill spindle 4 and beaten up. In doing so, they lay down against the metal piece 1 and the drill spindle with such pressure indicate that the drill bit can be easily removed. As a third embodiment for the removal of the drill shows Fig. 7 a nut 7 screwed onto the drilling machine spindle, which turns when it is unscrewed from the thread against the metal piece ι sets. Fig. 8 shows another version of the two-part metal piece 1. It differs from that shown in FIG only by the addition of a bolt 8, which prevents the unwanted parting of the two parts of the metal piece ι prevented.
