Abstract

Hollow drilling system, has an exhaust, a hollow drill (16) with a driving axle (4) can be withdrawn from the suction system without the use of tools. The driving axle is installed into hollow drill and has a through-hole, which serves for driving drill core residue by means of an output drive pins and for receiving the centering drilling holder (12).

Description

Die Erfindung betrifft eine Staubabsaugung und eine Anbohrzentrierung für Hohlbohrer mit einen werkzeuglosen Wechselsystem gemäß dem Oberbegriff des Anspruchs 1–4The The invention relates to a dust extraction and an Anbohrzentrierung for hollow drills with a tool-free change system according to the preamble of the claim 1-4

Für das Bohren von Löchern in Mauerwerk oder Beton – beispielsweise für das Einsetzen von Schalter oder Abzweigdosen einer elektrischen Installation, sind Hohlbohrer bekannt, die von einer Handbohrmaschine angetrieben werden. Da diese Bohrungen mit Diamantwerkzeugen sehr viel gesundheitsschädlichen Staub erzeugen, muss dieser Staub mittels eines Staubsaugers abgesaugt werden. Auch muss der Hohlbohrer bei Beginn des Bohrvorgangs mit einem Zentrierbohrhalter geführt werden, welcher nach dem der Hohlbohrer ca. 5 mm Bohrtiefe erreicht hat, entnommen werden muss.For drilling of holes in masonry or concrete - for example for the Inserting switches or junction boxes of an electrical installation, Holes are known which are powered by a hand drill become. Because these holes with diamond tools are very much harmful to health To generate dust, this dust must be extracted by means of a vacuum cleaner become. Also, the hollow drill must at the beginning of the drilling process with guided a center drill holder which achieves about 5 mm drilling depth after the hollow drill has to be taken.

Der Staub wird durch den Hohlbohrerboden der durch Öffnungen wie Löcher der Ausfräsungen versehen ist über die Saugglocke abgezogen. Bei dem Bohrvorgang passiert es häufig, das der Bohrkern sich vom Mauerwerk löst und im Hohlbohrer stecken bleibt und sich schwer entfernen lässt.Of the Dust is through the hollow bottom of the well through holes such as holes Milled out is over the suction bell pulled off. During the drilling process, it often happens that the drill core is released from the masonry and stuck in the hollow drill stays and can be difficult to remove.

Hier will die Erfindung Abhilfe schaffen in dem man der Hohlbohrer auf eine Antriebsachse montiert wird, welche Werkzeuglos vom Absaugsystem entfernt werden kann um so den Kern durch die Durchgangsbohrung in der Antriebsachse mit einem Austreibdorn zu entfernen.Here If the invention seeks to remedy in which one of the hollow drill on a drive axle is mounted, which is tool-free from the exhaust system can be removed so the core through the through hole to remove in the drive axle with a Austreibdorn.

Eine weitere Aufgabe der Erfindung ist, das die Durchgangsbohrung der Antriebsachse den Zentrierbohrhalter aufnimmt, welcher mit einem Ringmagnet im Hohlbohrer gehalten wird und mit 2 Nocken die in die Aussparrung der Antriebsachse eingreifen und so gegen Verdrehungen gesichert ist.A Another object of the invention is that the through hole of the Drive axle receives the Zentrierbohrhalter, which with a Ring magnet is held in the hollow drill and with 2 cams in the Aussparrung the drive axle engage and so against rotation is secured.

Das Hohlbohren in Mauerwerk, Stein oder Beton mit Staubabsaugung ist vorgeschrieben in geschlossenen Räumen. In offenen Räumen oder an Außenmauern wird meistens auf diese Staubabsaugung verzichtet. In diesem Fall ist die Absaugglocke störend, weil durch das Fehlen des Absaugschlauchs sie sich mit dem Bohrer dreht und eine Unwucht des Bohrsystems erzeugt.The Hollow drilling in masonry, stone or concrete with dust extraction is mandatory in closed rooms. In open spaces or on outer walls is mostly dispensed with this dust extraction. In this case is the exhaust bell disturbing, because by the absence of the suction hose they themselves with the drill rotates and generates an imbalance of the drilling system.

Hier soll die Erfindung Abhilfe schaffen in dem die Absaugglocke bei Bohrvorgängen ohne Staubabsaugung mittels Bajonettverschluss Werkzeuglos nach vorne aufgenommen werden kann.Here the invention is intended to remedy the case in which the suction bell drilling operations without dust extraction by means of bayonet lock without tools can be taken in the front.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen schematisch dargestellt und wird nachfolgend näher erläutert.One embodiment the invention is shown schematically in the drawings and will be closer below explained.

1 Zusammenstellung des Bohrsystems. 1 Compilation of the drilling system.

2 Hohlbohrer mit Antriebsachse 2 Hollow drill with drive axle

3 Austreibdorn 3 Austreibdorn

4 Zentrierbohrhalter mit Ringmagnet 4 Center drill holder with ring magnet

Das abgebildete Bohrsystem zeigt in 1 den Hohlbohrer (16) welcher auf die Antriebsachse (4) geschraubt ist die in die Antriebswelle (1) gesteckt wird und über eine Sechskantverbindung (4C) angetrieben wird. Die Antriebsachse (4) wird durch eine Stahlkugel (3) welche in eine Nute (4a) der Antriebsachse eingreift und mit der Schiebebüchse (11) das unbeabsichtigte raus fallen der Antriebsache (4) verhindert. Um den Hohlbohrer (16) mit Antriebsachse (4) zu entfernen muss die Schiebebüchse (11) in Richtung Druckfeder (10) geschoben werden, damit die Stahlkugel (3) in die Nute (11a) der Schiebebüchse (11) eintritt und so das Entfernen der Antriebsachse (4) zu ermöglichen. Das Einsetzen der Antriebsachse (4) erfolgt in umgekehrter Reihenfolge.The illustrated drilling system shows in 1 the hollow drill ( 16 ) which on the drive axle ( 4 ) is screwed into the drive shaft ( 1 ) and via a hexagonal connection ( 4C ) is driven. The drive axle ( 4 ) is replaced by a steel ball ( 3 ) which into a groove ( 4a ) engages the drive axle and with the sliding sleeve ( 11 ) the unintentional fall out of the drive thing ( 4 ) prevented. To the hollow drill ( 16 ) with drive axle ( 4 ) must remove the sliding sleeve ( 11 ) in the direction of the compression spring ( 10 ) so that the steel ball ( 3 ) into the groove ( 11a ) of the sliding sleeve ( 11 ) and so removing the drive axle ( 4 ). The insertion of the drive axle ( 4 ) takes place in reverse order.

Der Zentrierbohrer (15) wird mit dem Zentrierbohrhalter (12) in die Bohrung der Antriebsachse (4) gesteckt und mit den Mitnehmernocken (13) und mit der Ausnehmung (4b) der Antriebsachse (4) gegen verdrehen gesichert.The center drill ( 15 ) with the center drill holder ( 12 ) in the bore of the drive axle ( 4 ) and with the drive cam ( 13 ) and with the recess ( 4b ) of the drive axle ( 4 ) secured against twisting.

Um das Heraus fallen des Zentrierbohrhalters (12) zu verhindern ist ein Ringmagnet (14; am Zentrierbohrhalter (12) montiert. Der Zentrierbohrhalter (12) mit dem Zentrierbohrer (15) wird nach dem Anbohrvorgang entfernt.To fall out of the center drill ( 12 ) is a ring magnet ( 14 ; at the center drill holder ( 12 ) assembled. The center drill holder ( 12 ) with the center drill ( 15 ) is removed after the tapping process.

Löst sich beim Bohren der Bohrkern vom Mauerwerk und bleibt im Hohlbohrer (16) stecken, so wird der Hohlbohrer mit Antriebsachse (4) aus dem System entnommen und mittels Austreibdorn (18) durch die Bohrung (4b) der Antriebsachse (4) aus dem Hohlbohrer (16) nach vorne ausgetrieben.Dissolves when drilling the core of the masonry and remains in the hollow drill ( 16 ), the hollow drill with drive axle ( 4 ) removed from the system and by Austreibdorn ( 18 ) through the hole ( 4b ) of the drive axle ( 4 ) from the hollow drill ( 16 ) expelled to the front.

Beim Bohren ohne Absaugung wird die Absaugglocke (17) vom Lagerring (8) über einen Bajonettverschluss entfernt.When drilling without suction, the suction bell ( 17 ) from the bearing ring ( 8th ) via a bayonet lock.
