Eine Bohrmaschine mit einer solchen Einspannvorrichtung ist aus der WO 2005/118190 bekannt, wobei in der Einspannvorrichtung eine Einspannaussparung, die von einer Seitenwand umgeben ist und eine Aussparungsöffnung aufweist, zum Einspannen einesA drilling machine with such a clamping device is known from WO 2005/118190, wherein in the clamping device, a clamping recess, which is surrounded by a side wall and having a recess opening for clamping a
Ankers vorgesehen ist. Der Begriff „Anker" ist in diesem Zusammenhang sehr umfassend zu verstehen und soll jedes beliebige Element bezeichnen, das in einem Ankergrund verankerbar ist, um einen Gegenstand zu befestigen. Die Seitenwand ist in mehrere Spannlaschen unterteilt. Eine Außenseite der Seitenwand ist konisch ausgebildet und weist ein Außengewinde auf. Auf das Außengewinde ist ein Spannring aufschraubbar. Beim Aufschrauben des Spannrings werden die Spannlaschen nach innen gebogen, um den Anker in der Einspannaussparung einzuspannen. Zum Bohren wird der Anker, der deshalb auch als Sonotrode bezeichnet wird, in axialer Richtung (in Längsrichtung des Ankers) mit einer Frequenz, die im Ultraschallbereich zwischen etwa 20 kHz und 1000 MHz liegt, beaufschlagt. Aufgrund der hohen Frequenz wirken dabei sehr große Kräfte auf den Anker ein.Anchor is provided. The term "anchor" is to be understood in this context as being very comprehensive and is intended to designate any element that can be anchored in an anchorage in order to fasten an object The sidewall is subdivided into a plurality of tensioning straps An outer side of the sidewall is conically shaped When screwing on the clamping ring, the clamping straps are bent inwards to clamp the armature in the clamping recess For drilling, the armature, which is therefore also referred to as sonotrode, in the axial direction (in Longitudinal direction of the armature) with a frequency which lies in the ultrasonic range between approximately 20 kHz and 1000 MHz, because of the high frequency, very large forces act on the armature.
Ein Nachteil einer solchen Einspannvorrichtung liegt darin, dass ein guter Halt zwischen dem Anker und der Einspannvorrichtung nicht erreicht werden kann. Dadurch ist eine befriedigende Fixierung des Ankers oft nicht möglich, oder es kann zu einerA disadvantage of such a clamping device is that a good grip between the armature and the clamping device can not be achieved. As a result, a satisfactory fixation of the anchor is often not possible, or it can be to a
Relativbewegung und somit Reibung zwischen dem Anker und der Einspannvorrichtung kommen, die sich infolgedessen stark erwärmen und sogar miteinander verschweißen können. Zudem verschlechtert sich die Bohrleistung.Relative movement and thus friction between the armature and the jig come, which can heat up as a result, and even weld together. In addition, the drilling performance deteriorates.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Einspannvorrichtung für eine Bohrmaschine und eine Bohrmaschine zu schaffen, die es ermöglichen, einen Anker in der Einspannvorrichtung so einzuspannen, dass eine Relativbewegung und somit Reibung zwischen Einspannvorrichtung und Anker verhindert wird.The present invention has for its object to provide a clamping device for a drill and a drill, which allow a Anchor anchor in the jig so that a relative movement and thus friction between jig and anchor is prevented.
Die der Erfindung zugrunde liegende Aufgabe wird durch eine Einspannvorrichtung mit den Merkmalen des kennzeichnenden Teils des Patentanspruchs 1 und eineThe object underlying the invention is achieved by a clamping device with the features of the characterizing part of patent claim 1 and a
Bohrmaschine mit den Merkmalen des kennzeichnenden Teils des Patentanspruchs 5 gelöst.Drilling machine with the features of the characterizing part of claim 5 solved.
Erfindungsgemäß weist die Einspannaussparung einen Einführungsbereich, der so bemessen ist, dass ein Endabschnitt des Ankers, an dem ein Profil ausgebildet ist, in einer axialen Richtung durch die Aussparungsöffnung in den Einführungsbereich einführbar ist, und einen Eingriffsbereich auf, wobei der Einführungsbereich und der Eingriffsbereich ineinander übergehen, so dass der Endabschnitt des Ankers von dem Einführungsbereich im wesentlichen senkrecht zu der axialen Richtung in den Eingriffsbereich verschiebbar ist, wobei auf einer Innenseite der Seitenwand in demAccording to the invention, the chucking recess has an insertion portion dimensioned such that an end portion of the anchor on which a profile is formed is insertable into the insertion portion through the recess opening in an axial direction, and an engagement portion, wherein the insertion portion and the engagement portion are intermeshed so that the end portion of the armature is slidable from the insertion portion substantially perpendicular to the axial direction into the engagement portion, on an inner side of the side wall in the first position
Eingriffsbereich ein Gegenprofil ausgebildet ist, das geeignet ist, in das Profil an dem Endabschnitt des Ankers einzugreifen, so dass der Endabschnitt des Ankers nicht in axialer Richtung aus der Einspannaussparung herausziehbar ist.Engagement region is formed a counter-profile, which is adapted to engage in the profile at the end portion of the armature, so that the end portion of the armature can not be pulled out of the clamping recess in the axial direction.
Die axiale Richtung ist in diesem Zusammenhang die Richtung, in welcher gebohrt werden soll und in welcher sich die Längsrichtung des Ankers erstreckt. In diesem Zusammenhang bedeutet „Profil an dem Endabschnitt", dass es auf der Oberfläche des Endabschnitts mindestens einen Punkt gibt, der eine Tangente hat, die durch das Innere des Endabschnitts hindurchgeht. Dabei ist unter dem Profil vor allem ein Profil in axialer Richtung zu verstehen, d.h. es gibt auf der Oberfläche des Endabschnitts mindestens einen Punkt, der eine Tangente in axialer Richtung hat, die durch das Innere des Endabschnitts hindurchgeht. Entsprechend bedeutet in diesem Zusammenhang „Gegenprofil an der Innenseite der Seitenwand", dass es auf der Innenseite der Seitenwand mindestens einen Punkt gibt, der eine Tangente hat, die durch die Seitenwand hindurchgeht. Dabei soll unter dem Gegenprofil vor allem ein Gegenprofil in axialer Richtung verstanden werden, d.h. es gibt auf der Innenseite der Seitenwand mindestens einen Punkt, der eine Tangente in axialer Richtung hat, die durch die Seitenwand hindurchgeht. Vorteilhafterweise wird eine Erwärmung von Einspannvorrichtung und Anker aufgrund von Reibung zwischen diesen verhindert. Anders ausgedrückt kommt es durch das Profil und Gegenprofil zu einer Hinterschneidung die zu einer stabilen formschlüssigen Verbindung zwischen Anker und Einspannvorrichtung führt.The axial direction in this context is the direction in which drilling is to take place and in which the longitudinal direction of the armature extends. In this context, "profile at the end portion" means that there is at least one point on the surface of the end portion having a tangent that passes through the interior of the end portion, wherein the profile is primarily an axial profile That is, there is at least one point on the surface of the end portion that has a tangent in the axial direction that passes through the inside of the end portion. Accordingly, in this context, "counter profile on the inside of the side wall" means that it is on the inside of the side wall there is at least one point that has a tangent that passes through the sidewall. It should be understood by the counter profile especially a counter-profile in the axial direction, ie there is on the inside of the side wall at least one point which has a tangent in the axial direction, which passes through the side wall. Advantageously, heating of the clamping device and armature due to friction between them is prevented. In other words, it comes through the profile and counter profile to one Undercut which leads to a stable positive connection between the armature and jig.
In einer bevorzugten Ausführungsform ist das Gegenprofil als Innengewinde ausgebildet.In a preferred embodiment, the counter-profile is formed as an internal thread.
Dabei soll der Begriff Innengewinde ein unvollständiges Innengewinde einschließen, wie weiter unten erläutert.The term internal thread should include an incomplete internal thread, as explained below.
Vorteilhafterweise ist ein Innengewinde besonders geeignet, in ein Außengewinde einzugreifen, wie es typischerweise an einem Anker vorhanden sind.Advantageously, an internal thread is particularly suitable for engaging in an external thread, as is typically present at an anchor.
In einer Weiterbildung der bevorzugten Ausführungsform ist eine Auskragung auf einer Vorderseite der Einspannvorrichtung, auf der die Aussparungsöffnung ausgebildet ist, vorgesehen, um eine Mutter zu positionieren, durch welche der Endabschnitt des Ankers hindurchgeht. Mit der Mutter kann der Anker gegen die Vorderseite der Einspannvorrichtung gekontert werden, so dass er sich nicht beim Betrieb der Bohrmaschine in Richtung des Einführungsbereichs verschiebt, sondern festgehalten ist.In a further development of the preferred embodiment, a projection on a front side of the clamping device, on which the recess opening is formed, is provided in order to position a nut, through which the end section of the anchor passes. With the mother of the anchor can be countered against the front of the jig, so that it does not move during operation of the drill in the direction of the lead-in, but is held.
Vorteilhafterweise stellt eine Auskragung eine konstruktiv einfache und stabile Lösung dar, um den Anker in der Aussparung zu fixieren.Advantageously, a projection is a structurally simple and stable solution to fix the anchor in the recess.
In noch einer Weiterbildung der bevorzugten Ausführungsform ist die Auskragung als ein Ring ausgebildet, in dessen Mitte ein Bereich der Aussparungsöffnung liegt, der in dem Eingriffsbereich mündet.In a further embodiment of the preferred embodiment, the projection is formed as a ring, in the middle of which a region of the recess opening lies, which opens into the engagement region.
Vorteilhaferweise ist ein Ring besonders geeignet, um die Mutter zu positionieren.Advantageously, a ring is particularly suitable for positioning the nut.
Erfindungsgemäß betrifft die vorliegende Erfindung ferner eine Bohrmaschine mit einer erfindungsgemäßen Einspannvorrichtung.According to the invention, the present invention further relates to a drilling machine with a clamping device according to the invention.
Die Erfindung wird nachfolgend anhand der Zeichnungen näher beschrieben.The invention will be described in more detail with reference to the drawings.

Fig. 1 zeigt eine schematische Seitenansicht einer elektrischen Bohrmaschine mit einer Einspannvorrichtung 4. Die Bohrmaschine umfaßt außerdem einen Schwingungserreger 1 , einen Booster 2, ein Halterungselement 3 für die Einspannvorrichtung 4, einenFig. 1 shows a schematic side view of an electric drill with a clamping device 4. The drill also comprises a vibration exciter 1, a booster 2, a support member 3 for the chuck 4, a
Handgriff 5 und ein Stromkabel 6. Der Booster 2 erhöht die Schwingungsamplitude der vom Schwingungserreger 1 erzeugten axial gerichteten Schwingungen (Richtung des Doppelpfeils). An dem Halterungselement 3 ist die Einspannvorrichtung 4 über eine Schrumpfverbindung befestigt. In der Einspannvorrichtung 4 ist der Anker 7 mittels einer Mutter 8 eingespannt bzw. gekontert. An dem Handgriff 5 wird die elektrischeHandle 5 and a power cable 6. The booster 2 increases the amplitude of vibration generated by the vibration generator 1 axially directed vibrations (direction of the double arrow). On the support member 3, the clamping device 4 is attached via a shrink connection. In the chuck 4, the armature 7 is clamped or countered by means of a nut 8. On the handle 5, the electric
Bohrmaschine während des Bohrens gehalten. Über das Stromkabel 6 wird die elektrische Bohrmaschine mit Strom versorgt. Der aus dem Stand der Technik bekannte Anker 7 weist eine Gewindestange 9, eine Spreizhülse 10 und ein vorderes konisches Ende 1 1 auf und wird auch zum Bohren verwendet, wie in der WO 2005/1 18190 beschrieben.Drilling machine held during drilling. About the power cable 6, the electric drill is powered. The known from the prior art anchor 7 has a threaded rod 9, an expansion sleeve 10 and a front conical end 1 1 and is also used for drilling, as described in WO 2005/1 18190.
Fig. 2 zeigt eine perspektivische Ansicht der Einspannvorrichtung 4. Die Einspannvorrichtung 4 umfaßt in axialer Richtung einen hinteren zylindrischen Befestigungsabschnitt 12 zur Befestigung in dem Halterungselement 3 durch eine Schrumpfverbindung und einen vorderen verdickten Einspannabschnitt 13, in dem eineFig. 2 shows a perspective view of the chuck 4. The chuck 4 comprises in the axial direction a rear cylindrical attachment portion 12 for attachment in the support member 3 by a shrink connection and a front thickened chucking portion 13 in which a
Einspannaussparung 14 ausgebildet ist. Die Einspannaussparung 14 hat die Querschnittsform einer Superellipse (Zwischenform von Rechteck und Ellipse) und weist einen Einführungsbereich 15 und einen Eingriffsbereich 16 auf, die nebeneinander angeordnet sind und ineinander übergehen, und ist seitlich von einer Seitenwand 17 umgeben. Im Einführungsbereich 15 ist auf der Innenseite der Seitenwand 17 kein Profil vorgesehen, während im Eingriffsbereich 16 auf der Innenseite der Seitenwand 17 ein Profil 18 in Form eines unvollständigen Innengewindes vorgesehen ist. Unvollständig ist das Innengewinde, weil dessen Gewindegänge durch den Einführungsbereich 16 unterbrochen sind. Der Einführungsbereich 15 ist wegen der fehlenden Profils 18 weiter als der Eingriffsbereich 16. Daher kann in den Einführungsbereich 15 dieClamping recess 14 is formed. The clamping recess 14 has the cross-sectional shape of a superellipse (intermediate shape of rectangle and ellipse) and has an insertion portion 15 and an engaging portion 16, which are arranged side by side and merge into each other, and is laterally surrounded by a side wall 17. In the introduction area 15 no profile is provided on the inside of the side wall 17, while in the engagement area 16 on the inside of the side wall 17, a profile 18 is provided in the form of an incomplete internal thread. Incomplete is the internal thread, because its threads are interrupted by the introduction region 16. Because of the missing profile 18, the insertion area 15 is wider than the engagement area 16. Therefore, in the insertion area 15, the
Gewindestange mit dem Profil zunächst in axialer Richtung eingeführt werden (siehe Fig. 3) und diese dann im wesentlichen senkrecht zu der axialen Richtung in den Eingriffsbereich 16 verschoben werden, wo das Profil und das Gegenprofil 18 ineinandergreifen, so dass die Gewindestange 9 nicht aus der Einspannaussparung 14 in axialer Richtung gezogen werden kann. Während des Einführens kann die Gewindestange 9 dabei aufgrund ihres kreisförmigen Querschnitts teilweise auch in demThreaded rod with the profile are first introduced in the axial direction (see 3) and these are then displaced substantially perpendicular to the axial direction in the engagement region 16, where the profile and the counter-profile 18 engage, so that the threaded rod 9 can not be pulled out of the Einspannaussparung 14 in the axial direction. During insertion, the threaded rod 9 can also partially due to their circular cross-section in the
Eingriffsbereich 16 verlaufen. Um eine Aussparungsöffnung 21 auf einer flachen Vorderseite der Einspannvorrichtung 4, die sich senkrecht zu der axialen Richtung erstreckt, verläuft eine ringförmige Auskragung 19, in deren Mitte ein Bereich der Aussparungsöffnung 21 liegt, der in dem Eingriffsbereich 16 mündet. Die Auskragung 19 dient dazu, die Mutter 8, durch welche die Gewindestange 9 hindurchgeht, senkrecht zu der axialen Richtung zu positionieren, so dass die Gewindestange 9 nicht senkrecht zu der axialen Richtung verschoben werden kann. Alternativ kann auch in dem Einführungsbereich ein Profil, insbesondere ein Innengewinde vorgesehen sein. Die Aussparung muß in dem Einführungsbereich dann jedoch gegenüber dem Eingriffsbereich aufgeweitet sein, um das Einführen der Gewindestange zu ermöglichen.Engaging area 16 run. To a recess opening 21 on a flat front side of the chuck 4, which extends perpendicular to the axial direction, extends an annular projection 19, in the middle of which a portion of the recess opening 21 is located, which opens into the engagement region 16. The projection 19 serves to position the nut 8, through which the threaded rod 9 passes, perpendicular to the axial direction, so that the threaded rod 9 can not be displaced perpendicular to the axial direction. Alternatively, a profile, in particular an internal thread, may also be provided in the introduction region. However, the recess must then be widened in the insertion area relative to the engagement area to allow the insertion of the threaded rod.
Fig. 3 zeigt eine Schnittansicht der Einspannvorrichtung 4 mit eingeführter Gewindestange 9. Die Einspannaussparung 14 ist als vorne offenes Sackloch mit der Querschnittsform einer Superellipse ausgebildet, das von einer Seitenwand 17 umgeben ist und hinten durch eine Rückwand 20 verschlossen ist. Ein Außengewinde der3 shows a sectional view of the clamping device 4 with inserted threaded rod 9. The clamping recess 14 is designed as a front open blind hole with the cross-sectional shape of a superellipse, which is surrounded by a side wall 17 and rear closed by a rear wall 20. An external thread of
Gewindestange 9 greift in das unvollständige Innengewinde 18 im Eingriffsbereich 16 ein. Die Mutter 8 liegt seitlich an der Auskragung 19 an, so dass die Gewindestange 9 nicht senkrecht zu der axialen Richtung verschoben werden kann und folglich nicht aus der Einspannaussparung 14 gezogen werden kann. Die Mutter 8 ist fest angezogen, so dass das Außengewinde der Gewindestange 9 in axialer Richtung fest gegen dasThreaded rod 9 engages in the incomplete internal thread 18 in the engagement region 16 a. The nut 8 bears laterally against the projection 19, so that the threaded rod 9 can not be displaced perpendicular to the axial direction and consequently can not be pulled out of the clamping recess 14. The nut 8 is tightened so that the external thread of the threaded rod 9 in the axial direction firmly against the
Innengewinde 18 in dem Eingreifbereich 16 gedrückt wird und es kein Spiel zwischen der Gewindestange 9 und der Einspannvorrichtung 4 gibt. Diese Konterung und die Auskragung 19 verhindern eine Verschiebung des Ankers 7 aus dem eingespannten Zustand zurück in den Einführungsbereich 15. Zum Ausspannen des Ankers 7 muss durchgehend die Mutter 8 gelöst und der Anker 7 zum Einführungsbereich 15 verschoben werden. Dann kann die Einspannvorrichtung 4 vom Anker 7 abgezogen werden. Internal thread 18 is pressed in the engaging portion 16 and there is no play between the threaded rod 9 and the clamping device 4. This lock and the projection 19 prevent a displacement of the armature 7 from the clamped state back into the insertion region 15. To relax the armature 7, the nut 8 must be continuously released and the armature 7 is moved to the insertion region 15. Then the clamping device 4 can be deducted from the armature 7.
