Description

STÄNDER FÜR EINE STEINBEARBEITUNGSMASCHINE, INSBE¬ SONDERE EINE KERNBOHRMASCHINE STAND FOR A STONE WORKING MACHINE, IN PARTICULAR A CORE DRILLING MACHINE
Die Erfindung betrifft einen Ständer für eine Steinbearbeitungsma¬ schine, insbesondere eine Kernbohrmaschine, mit einer Tragschiene und einem an dieser höhenverstellbar geführten Schlitten mit einer Werkzeughalterung, an welcher ein Antriebsaggregat und ein an letzterem drehverbundenes Werkzeug befestigbar ist, dessen Dreh¬ achse parallel zur Tragschiene verläuft und die Vorschubbewegung durch eine Verstellung der Werkzeughalterung entlang der Trag¬ schiene erfolgt.The invention relates to a stand for a stone working machine, in particular a core drilling machine, with a mounting rail and a slide which is guided on this in a height-adjustable manner with a tool holder, to which a drive unit and a tool connected to the latter, the axis of rotation of which runs parallel to the mounting rail, can be fastened and the feed movement takes place by adjusting the tool holder along the support rail.
Bei einer gattungsmässigen Kernbohrmaschine nach der Patentschrift EP-B l 0 321 395 steht die Tragschiene vertikal oder in einem be¬ stimmten Winkel zur Vertikalen auf dem Boden oder dergleichen. An dieser Tragschiene ist ein Halteelement höhenverstellbar angeordnet, an welchem ein als Elektromotor ausgebildetes Antriebsaggregat befestigt ist. An die Antriebswelle dieses Elektromotors kann dann gleichachsig ein Kern- oder Hohlbohrer (Hohlfräser) über eine Kupplungseinrichtung angeflanscht werden. Durch die üblicherweise von Hand über einen Hebel erzeugte Vorschubbewegung wird dieses Halteelement und mit ihm der vom Elektromotor in Drehung ver¬ setzte Kernbohrer entlang seiner Drehachse vorwärtsgeschoben und bewirkt einen Ausschnitt eines zylindrischen Loches in einen Beton¬ oder Gesteinsboden oder ähnlichem. Nachteilig hierbei ist, dass beim Auswechseln oder bei einem Verlängern des Kernbohrers die gesam¬ te Tragschiene angehoben werden muss, damit der alte Kernbohrer losgekuppelt werden kann und ein neuer einsetzbar ist.In the case of a generic core drilling machine according to the patent specification EP-B 10321 395, the mounting rail stands vertically or at a certain angle to the vertical on the floor or the like. A height-adjustable holding element is arranged on this mounting rail, to which a drive unit designed as an electric motor is attached. A core or hollow drill (hollow milling cutter) can then be flanged to the drive shaft of this electric motor coaxially via a coupling device. By means of the feed movement usually produced by hand using a lever, this holding element and with it the core drill set in rotation by the electric motor are pushed forward along its axis of rotation and causes a cutout of a cylindrical hole in a concrete or stone floor or the like. The disadvantage here is that when the core drill is replaced or extended, the entire mounting rail must be raised so that the old core drill can be uncoupled and a new one can be used.
Aufgabe der vorliegenden Erfindung besteht demgegenüber darin, einen Ständer für eine Steinbearbeitungsmaschine nach der eingangs beschriebenen Gattung zu schaffen, mittels dem eine schnelle Ver¬ längerung oder ein Wechsel des an ihm ankuppelbaren Werkzeuges ermöglicht ist und dieser Ständer dennoch eine sehr stabile Halte- rung des daran befestigbaren Werkzeuges bietet.In contrast, the object of the present invention is to provide a stand for a stone processing machine of the type described in the introduction, by means of which a rapid extension or a change of the tool which can be coupled to it is made possible, and this stand nevertheless provides a very stable holding of the same attachable tool offers.
Erfindungsgemäss ist die Aufgabe dadurch gelöst, dass die Werk¬ zeughalterung über eine Schwenkeinrichtung am Schlitten gehalten ist, wobei mittels dieser Schwenkeinrichtung die Werkzeughalterung quer zur Werkzeugdrehachse wegschwenkbar und/oder vom Schlitten wegnehmbar ist, indessen in der Bearbeitungsposition dieses Werkzeug zur Tragschiene mittels der Schwenkeinrichtung fixierbar ist.According to the invention, the object is achieved in that the tool holder is held on the slide via a pivoting device, the tool holder being pivotable away from the slide and / or removable from the slide by means of this pivoting device, but in the processing position of this tool can be fixed to the mounting rail by means of the pivoting device is.
Bei einer sehr vorteilhaften Lösung weist die Schwenkeinrichtung zwei parallel zur Tragschiene verlaufende, im Schlitten nebeneinan¬ der angeordnete Achsen auf, die einzeln oder zusammen mit der Werkeughalterung in oder ausser Eingriff bringbar sind.In a very advantageous solution, the pivoting device has two axes which run parallel to the mounting rail and are arranged next to one another in the slide and which can be brought into or out of engagement individually or together with the tool holder.
Mit dieser erfindungsgemässen Ausbildung des Ständers ergibt sich eine erhebliche Vereinfachung der Bedienbarkeit und Manipulierung des an diesem drehbar gelagerten Werkzeuges, insbesondere eines Kernbohrers. So kann das Werkzeug verlängert werden, ohne dass der Ständer von diesem gelöst und auf die Seite gestellt werden muss, dadurch überdies gewährleistet ist, dass das verlängerte Werkzeug am Ständer wieder in derselben Position wie das vorherige verbrauchte befestigt werden kann.With this design of the stand according to the invention, there is a considerable simplification of the usability and manipulation of the tool, in particular one, which is rotatably mounted thereon Core drill. In this way, the tool can be extended without having to detach the stand from it and set it aside, which also ensures that the extended tool can be attached to the stand again in the same position as the previous one used.
Ausführungsbeispiele der Erfindung sowie weitere Vorteile dersel¬ ben sind nachfolgend anhand der Zeichnung näher erläutert. Es zeigt:Exemplary embodiments of the invention and further advantages thereof are explained in more detail below with reference to the drawing. It shows:

Fig. l zeigt einen Ständer 10 für eine Steinbearbeitungsmaschine, die im vorliegenden Ausführungsbeispiel als sogenannte Universal- Kernbohrmaschine ausgeführt ist. Dieser Ständer 10 besteht im we¬ sentlichen aus einem Schlitten 20, einer diesen führenden Trag¬ schiene 12, einen letztere über ein Gelenk 14 haltender Stützfuss 15 sowie aus zwei Stützelementen 17, welche am oberen Ende gelenkig an einem an der Tragschiene 12 festklemmbaren Führungsnocken 27 und am unteren Ende gelenkig an der Hinterseite des Stützfusses 15 gehalten sind. An dem an der Tragschiene 12 höhenverstellbar geführten Schlitten 20 ist eine Werkzeughalterung 25 angebracht, an welcher ein Antriebsaggregat 19, bspw. ein Bohrmotor, mittels einer Klemmeinrichtung 25' befestigt ist. Dieses Antriebsaggregat 19 hat unten eine Motorwelle 26, an welche über eine Kupplung 21 , wie sie zum Beispiel in der Patentschrift EP-Bl 0 321 395 ausführlich erläutert ist, ein als Kernbohrer dargestelltes Werkzeug 1 8 an¬ gekoppelt ist. Die Drehachse 18' von letzterem verläuft dabei parallel zur Tragschiene 12 und die Vorschubbewegung des Werk¬ zeuges 18 erfolgt durch eine Verstellung der Werkzeughalterung 25 entlang der Tragschiene 12 vom Ständer 10. Das Werkzeug wird zu diesem Zwecke vom Antriebsaggregat 19 mit einer entsprechenden Drehzahl gedreht und durch einen Vorschub in Achsrichtung des Kernbohrers erzeugt dieser einen ringförmigen Ausschnitt in den die Auflagefläche 11 bildenden Betonboden oder dergleichen.Fig. L shows a stand 10 for a stone processing machine, which is designed in the present embodiment as a so-called universal core drilling machine. This stand 10 consists essentially of a slide 20, a support rail 12 guiding it, a support leg 15 holding the latter via a joint 14, and two support elements 17 which are articulated at the upper end to a guide cam 27 which can be clamped to the support rail 12 and are held in an articulated manner on the rear side of the support foot 15 at the lower end. A tool holder 25 is attached to the slide 20, which is adjustable in height on the mounting rail 12, to which a drive unit 19, for example a drill motor, is fastened by means of a clamping device 25 '. This drive unit 19 has at the bottom a motor shaft 26, to which a tool 1 8, shown as a core drill, is coupled via a coupling 21, as described in detail for example in the patent specification EP-Bl 0 321 395. The axis of rotation 18 'of the latter runs parallel to the support rail 12 and the feed movement of the tool 18 takes place by adjusting the tool holder 25 along the support rail 12 from the stand 10. The tool is closed For this purpose, it is rotated by the drive unit 19 at a corresponding speed and, by means of a feed in the axial direction of the core drill, this produces an annular cutout in the concrete floor or the like which forms the support surface 11.
Erfindungsgemäss ist die Werkzeughalterung 25 über eine Schwenk¬ einrichtung 30 am Schlitten 20 gehalten, wobei mittels dieser Schwenkeinrichtung 30 die Werkzeughalterung 25 quer zur Werk¬ zeugdrehachse 18' wegschwenkbar und/oder vom Schlitten 20 weg¬ nehmbar ist, indessen in der Bearbeitungsposition dieses Werkzeug 18 zur Tragschiene 12 mittels der Schwenkeinrichtung 30 fixierbar ist.According to the invention, the tool holder 25 is held on the slide 20 via a swivel device 30, the swivel device 30 being able to swivel the tool holder 25 transversely to the tool axis of rotation 18 'and / or to remove it from the slide 20, but in the machining position of this tool 18 can be fixed to the mounting rail 12 by means of the swivel device 30.
Der Schlitten 20 ist vorteilhaft selbsthemmend in von der Trag¬ schiene 12 gebildeten Schienen 13 geführt und er wird über eine von Hand betätigbare Vorschubeinrichtung entlang dieser Tragschiene 12 bewegt. Von dieser Vorschubeinrichtung ist nur gerade eine über einen Hebel oder dergleichen bewegbare Drehachse 21 ersichtlich, die mit einem Ritzel drehverbunden ist, welches mit einer an der Vorderseite der Tragschiene 12 angeordneter Zahnstange 16 in Ein¬ griff steht und bei dessen Drehung eine Höhenverstellung des Schlittens 20 bewirkt.The slide 20 is advantageously self-locking in rails 13 formed by the support rail 12 and is moved along this support rail 12 by a manually operable feed device. From this feed device, only an axis of rotation 21 that can be moved via a lever or the like can be seen, which is rotationally connected to a pinion which engages with a toothed rack 16 arranged on the front side of the mounting rail 12 and, when it rotates, a height adjustment of the slide 20 causes.
Die Tragschiene 12 kann im übrigen um das am Stützfuss 15 vorge¬ sehene Gelenk 14 beispielsweise in eine Position P12 geschwenkt werden, wodurch die Richtung der Werkzeug-Vorschubbewegung in bezug auf die Auflagefläche 11 vom Stützfuss 15 um einen zwischen 90° - wie gezeigt - und annähernd 15° festlegbaren Winkel einstell¬ bar ist. Damit lässt sich beispielsweise in einen Betonboden eine schräge Bohrung mit einem Durchmesser entsprechend des Aussen- durchmessers des Kernbohrers einfräsen. Der Stützfuss 15 ist fer¬ nerhin mit Nivellierschrauben 15' versehen, mit welchen sich die Tragschiene 12 und demzufolge die Bohrrichtung des Kernbohrers zu der Auflagefläche 11 genau justieren lässt. Gemäss der Fig. 2 ist der Schlitten 20 in seinem Querschnitt U-för- mig ausgebildet und er weist seitlich je zwei Führungsbolzen 23 auf, welche in die zueinander gegenüberliegenden Schienen 13 an der Tragschiene 12 eingreifen und dabei zumindest auf der einen Schie¬ nenseite senkrecht zur Tragschiene 12 einstellbar sind. Mit dieser Verstellbarkeit dieser Führungsbolzen 23 kann die aufzuwendende Kraft für das Verschieben des Schlittens 20 wunschgemäss festgelegt werden. Vorteilhaft ist diese Einstellung so gewählt, dass der Schlitten selbsthemmend an dieser Tragschiene geführt ist, wenn das Antriebsaggregat nicht montiert ist.The support rail 12 can, moreover, be pivoted about the joint 14 provided on the support leg 15, for example into a position P12, as a result of which the direction of the tool feed movement with respect to the contact surface 11 of the support leg 15 by between 90 ° - as shown - and approximately 15 ° definable angle is adjustable. This can be used, for example, to mill an oblique hole in a concrete floor with a diameter corresponding to the outside diameter of the core drill. The support foot 15 is also provided with leveling screws 15 ', with which the mounting rail 12 and consequently the drilling direction of the core drill relative to the contact surface 11 can be precisely adjusted. According to FIG. 2, the cross section of the slide 20 is U-shaped and it has two guide pins 23 on each side, which engage in the rails 13 opposite one another on the mounting rail 12 and at least vertically on one side of the rail to the mounting rail 12 are adjustable. With this adjustability of these guide bolts 23, the force to be moved for moving the carriage 20 can be determined as desired. This setting is advantageously selected such that the slide is guided on this mounting rail in a self-locking manner when the drive unit is not mounted.
Die Schwenkeinrichtung 30 weist zwei parallel zur Tragschiene 12 verlaufende, im Schlitten 20 nebeneinander angeordnete Achsen 32 auf. die einzeln oder zusammen mit der Werkeughalterung in oder ausser Eingriff bringbar sind. Diese seitlich an der Werkzeughalte¬ rung 25 angeordneten Achsen 32 ermöglichen ein Wegschwenken dieser Werkzeughalterung 25 von der Bearbeitungsposition Pl aus beidseitig um je einen Winkel von annähernd 180° in je eine das Werkzeug freigebende Stellung P2 bzw. P3, infolgedessen das ange¬ deutete Werkzeug 18, welches sich beispielsweise in einer Bohrung befindet, ungehindert senkrecht nach oben herausgehoben werden kann, ohne dass der Ständer weggetragen werden müsste. Die Werk¬ zeughalterung kann dabei wahlweise auf die eine oder andere Seite ausgeschwenkt werden und die Schwenkebene befindet sich senk¬ recht zur Drehachse 1 8' des Werkzeuges 18.The swiveling device 30 has two axes 32, which run parallel to the mounting rail 12 and are arranged next to one another in the slide 20. which can be brought into or out of engagement individually or together with the tool holder. These axes 32 arranged on the side of the tool holder 25 enable this tool holder 25 to be pivoted away from the machining position P1 on both sides by an angle of approximately 180 ° into a position P2 or P3 which releases the tool, consequently the indicated tool 18 , which is located, for example, in a bore, can be lifted unhindered vertically upwards without the stand having to be carried away. The tool holder can optionally be swung out to one side or the other and the swivel plane is perpendicular to the axis of rotation 18 ′ of the tool 18.
Bei dieser Draufsicht sind ferner die beiden Stützelemente 17 er¬ sichtlich, die einerseits am Stützfuss 15 und andererseits an dem Führungsnocken 27 gehalten sind. Der Führungsnocken 27 ist eben¬ falls in Führungen der Tragschiene 12 höhenverstellbar geführt und mittels einer sich durch diesen erstreckenden Schraube 28 lässt sich dieser Führungsnocken 27 in einer bestimmten Position festklemmen.This top view also shows the two support elements 17, which are held on the one hand on the support foot 15 and on the other hand on the guide cam 27. The guide cam 27 is also vertically adjustable in guides of the mounting rail 12 and by means of a screw 28 extending through this guide cam 27 can be clamped in a certain position.
Die in Fig.3 ausschnittweise verdeutlichte Achse 32 der Schwenkein¬ richtung 30 weist jeweils zwei koaxial zueinander im Schlitten 20 angeordnete Achsteile 33, 34 auf, welche an dem einander zugekehr- ten Ende je ein gegenläufiges Aussengewinde 33', 34' aufweisen, die in einer im Schlitten 20 drehbar geführten Mutter 35 verschiebbar gehalten sind und dabei jeweils passend in eine Bohrung 36, 37 der den Schlitten 20 umgreifenden Werkzeughalterung 25 eingreifen oder aus dieser Bohrung 36, 37 herausschiebbar sind, wobei letztere leicht konisch ausgebildet sind und somit die Achsteile 33, 34 darin formschlüssig festgehalten sind. Diese Achsteile 33, 34 sind mit Ausnahme der Gewinde gleich ausgebildet und in symmetrischer An¬ ordnung zur Mutter 35 im Schlitten 20 axial verstellbar gehalten. Sie sind überdies verdrehsicher in einem jeweiligen Führungsteil 39 angeordnet und ihnen sind überdies Bohrungen 41 zwecks Schmie¬ rung ihrer Führungsflächen zugeordnet.The axis 32 of the swivel device 30, which is shown in detail in FIG. 3, has two axis parts 33, 34 arranged coaxially to one another in the slide 20, which on the mutually facing th end each have an opposing external thread 33 ', 34', which are held displaceably in a nut 35 rotatably guided in the slide 20 and in each case fit into a bore 36, 37 of the tool holder 25 encompassing the slide 20 or from this bore 36, 37 can be pushed out, the latter being slightly conical and thus the axle parts 33, 34 are held therein in a form-fitting manner. With the exception of the threads, these axle parts 33, 34 are of identical design and are held axially adjustable in the carriage 20 in a symmetrical arrangement with the nut 35. In addition, they are arranged in a respective guide part 39 in such a way that they cannot rotate, and they are also assigned bores 41 for the purpose of lubricating their guide surfaces.
In der gezeigten Position ist die Achse 32 ausser Eingriff gebracht und die dadurch gelöste Werkzeughalterung 25 kann demzufolge um die andere, nicht dargestellte Achse 32 geschwenkt werden, sofern diese in Eingriff steht. Diese Achsen 32 sind daher alternativ als Schwenkachse der Werkzeughalterung 25 einsetzbar. Beim Lösen beider Achsen kann die Werkzeughalterung 25 vom Schlitten 20 und damit von der Tragschiene 12 insgesamt weggenommen werden. Die Mutter 35 ist von aussen zugänglich und kann von Hand in der einen oder andern Richtung gedreht werden.In the position shown, the axis 32 is disengaged and the tool holder 25 thus loosened can consequently be pivoted about the other axis 32, not shown, if this is in engagement. These axes 32 can therefore alternatively be used as the pivot axis of the tool holder 25. When loosening both axes, the tool holder 25 can be removed from the slide 20 and thus from the mounting rail 12 as a whole. The nut 35 is accessible from the outside and can be turned by hand in one direction or the other.
Gemäss der Fig.4 ist beispielsweise beim Anbringen einer horizonta¬ len Bohrung in eine Wand oder dergleichen an der in vorliegendem Falle vertikal angeordneten Tragschiene 12 eine an dieser mittels einer Klemme 42 befestigte zusätzliche Tragschiene 40 vorgesehen. An dieser im Querschnitt vorteilhaft gleich wie die Tragschiene 12 ausgebildeten Tragschiene 40 ist wiederum der Schlitten 20 längs¬ verschiebbar geführt und an letzterem die Werkzeughalterung 25 über eine Schwenkeinrichtung 30 befestigt. Die Werkzeughalterung 25 kann gemäss der Erfindung durch diese oben ausführlich um¬ schriebene Schwenkeinrichtung 30 quer zur Drehachse des horizontal ausgerichteten Werkzeuges geschwenkt werden. Die Klemme 42 weist einen Basisteil 43 auf, der höhenverstellbar an der Tragschiene 12 geführt und an dieser in einer beliebigen Position fixiert werden kann. Mittels dieser Klemme 42 kann somit die Tragschiene 40 wie gezeigt in horizontaler oder aber in einer geneigten, bis hin zu einer vertikalen Stellung angeordnet werden. An dem Basisteil 43 ist ein Klemmstück 44 mit einer senkrecht zur Tragschiene 12 sich erstrek- kenden Drehachse drehbar gehalten, sofern der Basisteil 43 von der Tragschiene gelöst ist, hingegen in der durch Schrauben 45 bewirk¬ ten fixierten Stellung ist auch das Klemmstück 44 gegen Verdrehung gesichert. Letzteres hat eine Führungsbahn 47, in welcher die Tragschiene 40 längsverschiebbar geführt ist und mittels einer Klemmbacke 48 sowie einer Schraube 46 fixiert werden kann.According to FIG. 4, for example, when a horizontal bore is made in a wall or the like, an additional mounting rail 40 fastened to the mounting rail 12, which is arranged vertically in the present case, is provided thereon by means of a clamp 42. On this support rail 40, which is advantageously of the same cross-section as the support rail 12, the slide 20 is in turn guided in a longitudinally displaceable manner and the tool holder 25 is fastened to the latter via a swivel device 30. According to the invention, the tool holder 25 can be pivoted transversely to the axis of rotation of the horizontally oriented tool by means of this pivot device 30, which has been described in detail above. The clamp 42 has a base part 43, which is guided in a height-adjustable manner on the mounting rail 12 and fixed thereon in any position can. By means of this clamp 42, the support rail 40 can thus be arranged as shown in a horizontal position or in an inclined position up to a vertical position. On the base part 43, a clamping piece 44 is rotatably held with an axis of rotation extending perpendicular to the mounting rail 12, provided that the base part 43 is detached from the mounting rail, but in the fixed position caused by screws 45, the clamping piece 44 is also against rotation secured. The latter has a guide track 47, in which the mounting rail 40 is guided in a longitudinally displaceable manner and can be fixed by means of a clamping jaw 48 and a screw 46.
Der Ständer und insbesondere auch die Schwenkeinrichtung könnten selbstverständlich in anderer Konstruktion verwirklicht werden. Mit dem erläuterten Ausführungsbeispiel ist die vorliegende Erfindung jedoch genügend dargetan. The stand and in particular also the swivel device could of course be realized in a different construction. With the illustrated embodiment, however, the present invention is sufficiently demonstrated.
