Description

Die Erfindung bezeichnet einen Maschinenständer mit einer Maschinenkupplung für eine transportable Werkzeugmaschine, insbesondere zum Antrieb einer Kernbohrkrone zum Bohren von Beton und Mauerwerk.The invention refers to a machine frame with a machine coupling for a portable machine tool, in particular for driving a core bit for drilling concrete and masonry.

Die beim Kernbohren von Gestein notwendigen hohen Drehmomente und Vorschubkräfte werden üblicherweise von der Werkzeugmaschine gegen einen Maschinenständer aufgebracht, der fest mit dem Untergrund verbunden ist. Dabei werden die Kräfte von der Werkzeugmaschine über einen versetzbaren, mit einem Maschinenkupplungsteil zur zentralen Befestigung der Werkzeugmaschine ausgebildeten, Führungsschlitten symmetrisch auf eine Führungsschiene und weiter über eine Bodenplatte in den Untergrund übertragen.The necessary during the core drilling of rock high torques and feed forces are usually applied by the machine tool against a machine stand, which is firmly connected to the ground. The forces are transmitted from the machine tool via a displaceable, with a machine coupling part for central mounting of the machine tool, guide carriage symmetrically on a guide rail and further via a bottom plate in the ground.

Nach der DE3237057 ist an einer Führungsschiene eines Maschinenständers ein versetzbarer Führungsschlitten mit einem Schlittenkupplungsteil mit einer Spannfläche angeordnet, an dem über ein koppelbar zugeordnetes Maschinenkupplungsteil mit einer zugeordneten Spannfläche eine Werkzeugmaschine über eine spitzwinkelige, exponiert hervorstehende Nase (bei üblicher Montage unten) in den Schlittenkupplungsteil eingehängt, in die Verspannposition verschwenkt und sicher arretiert und über einen einsteckbaren Hebel verspannt werden kann, indem mittels des Hebels ein umfänglich freiliegender Bolzen des Schlittenkupplungsteils exzentrisch versetzt wird.After DE3237057 is on a guide rail of a machine stand a displaceable guide carriage with a carriage coupling part arranged with a clamping surface on which a machine-coupling part with an associated clamping surface via a coupling-associated, a machine tool via an acute-angled, exposed protruding nose (in the usual assembly below) mounted in the carriage coupling part, in the Can be pivoted clamping position and securely locked and clamped by a plug-in lever by means of the lever, a circumferentially exposed bolt of the carriage coupling part is offset eccentrically.

Die Aufgabe der Erfindung besteht in der Realisierung eines Maschinenständers mit einer Maschinenkupplung mit einem kleineren und weniger auskragenden Maschinenkupplungsteil. Ein weiterer Aspekt besteht in der technologisch einfacheren Herstellung insbesondere des Maschinenkupplungsteils.The object of the invention is the realization of a machine stand with a machine coupling with a smaller and less cantilevered machine coupling part. Another aspect is the technologically simpler production, in particular of the machine coupling part.

Die Aufgabe wird im Wesentlichen durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The object is essentially achieved by the features of claim 1. Advantageous developments emerge from the subclaims.

So weist ein Maschinenständer eine am Führungsschlitten angeordnete Maschinenkupplung für eine transportable Werkzeugmaschine auf, wobei am Führungsschlitten ein Schlittenkupplungsteil mit einer Spannfläche angeordnet ist, dem ein Maschinenkupplungsteil für die Werkzeugmaschine mit einer Spannfläche koppelbar zugeordnet ist, wobei das Maschinenkupplungsteil zwei zumindest teilweise umfänglich freiliegende Bolzen aufweist, die hinter zwei koppelbar zugeordnete Haken des Schlittenkupplungsteils einhängbar sind, wobei zumindest ein erster Haken im Schlittenkupplungsteil entlang dessen Spannfläche versetzbar ist.Thus, a machine stand has a machine coupling arranged on the guide carriage for a transportable machine tool, wherein the guide carriage has a Carriage coupling part is arranged with a clamping surface, which is assigned a machine coupling part for the machine tool coupled with a clamping surface, wherein the machine coupling part has two at least partially circumferentially exposed bolts which are hooked behind two coupling associated hooks of the carriage coupling part, wherein at least a first hook in the carriage coupling part along whose clamping surface is displaceable.

Durch die beiden am Haken des Schlittenkupplungsteils einhängbaren, zumindest teilweise umfänglich freiliegenden Bolzen des Maschinenkupplungsteils ist eine exponiert hervorstehende Nase verzichtbar, wodurch das Maschinenkupplungsteil kleiner ausführbar ist und die zumindest teilweise Integration in das Maschineninnere besteht. Zudem ist über die beiden Bolzen die Werkzeugmaschine auch im unarretierten Zustand an zwei Orten eingehängt und somit unschwenkbar fixiert. Die Herstellung des Maschinenkupplungsteils ist technologisch einfach, da als Bolzen Standardteile verwendbar sind, die nur zumindest teilweise umfänglich freiliegend beanspruchbar festgelegt sein müssen, bspw. in Löchern von zwei planparallelen Platten des Maschinenkupplungsteils.By the two hooked on the hook of the carriage coupling part, at least partially circumferentially exposed bolts of the machine coupling part an exposed protruding nose is dispensed with, whereby the machine coupling part is smaller executable and at least partially integration into the machine interior. In addition, the machine tool is hung in two places over the two bolts even in the unlocked state and thus fixed unschwenkbar. The production of the machine coupling part is technologically simple, since standard parts can be used as bolts, which only need to be fixed at least partially exposed to the circumference, for example in holes of two plane-parallel plates of the machine coupling part.

Vorteilhaft ist der erste Haken durch einen Exzentermechanismus versetzbar, wodurch die Arretierung selbstarretierend ausgebildet ist.Advantageously, the first hook is displaceable by an eccentric mechanism, whereby the lock is designed self-locking.

Vorteilhaft ist der Exzentermechanismus als ein in einer Zylinderhülse geführter Exzenterbolzen ausgebildet, der weiter vorteilhaft eine radial sprialförmige Kontaktfläche aufweist, wodurch verschleissarm hohe Verspannkräfte aufbringbar sind.Advantageously, the eccentric mechanism is designed as an eccentric bolt guided in a cylinder sleeve, which furthermore advantageously has a radially sprial-shaped contact surface, as a result of which high-tensioning forces can be applied with little wear.

Vorteilhaft weist der Exzentermechanismus eine Hebelaufnahme zum Einstecken eines Hebels auf, wodurch bei zweckentsprechender Verwendung der Hebel selbst entfernbar ist und nicht stört.Advantageously, the eccentric mechanism has a lever receptacle for inserting a lever, whereby the lever itself can be removed and does not interfere with appropriate use.

Vorteilhaft ist der erste Haken an einem Schwenkhebel ausgebildet, der über den Exzentermechanismus verschwenkbar ist, wodurch die Verspannkraft übersetzbar ist.Advantageously, the first hook is formed on a pivot lever, which is pivotable via the eccentric mechanism, whereby the clamping force is translatable.

Vorteilhaft ist am Schlittenkupplungsteil ein zweiter Haken starr festgelegt, wodurch dieser technologisch einfach montierbar ist, bspw. durch eine Passbolzenverschraubung.Advantageously, a second hook is rigidly fixed to the carriage coupling part, whereby this is technologically easy to assemble, for example. By a fitting bolt.

Vorteilhaft sind die Spannflächen geneigt zur Versetzungsrichtung des Führungsschlittens angeordnet, wodurch bei Verwendungen in horizontaler Versetzungsrichtung ein allfällig auf den Spannflächen befindliches Wasser selbstständig abfliessen kann.Advantageously, the clamping surfaces are arranged inclined to the direction of displacement of the guide carriage, whereby when used in the horizontal direction of dislocation any befindliches on the clamping surfaces water can drain off independently.

Vorteilhaft sind sowohl an dem Maschinenkupplungsteil als auch an dem Schlittenkupplungsteil jeweils zwei gegeneinander orientierte Führungsflächen ausgebildet, die senkrecht zu den Spannflächen verlaufen, wodurch eine Arbeitsachse der Werkzeugmaschine definiert zu der Versetzungsrichtung des Führungsschlittens ausgerichtet ist.Two mutually oriented guide surfaces are advantageously formed both on the machine coupling part and on the carriage coupling part, which run perpendicular to the clamping surfaces, whereby a working axis of the machine tool is defined aligned to the displacement direction of the guide carriage.

Das Schlittenkupplungsteil ist im allgemeinen Fall ein integraler Bestandteil des Führungsschlittens. Doch vorteilhaft sind mit dem Schlittenkupplungsteil Nutensteine verbunden, die in senkrecht zur Versetzungsrichtung eines separaten Führungsschlittens verlaufende T-förmige Quernuten eingreifen, wodurch eine Justage der Lage des Schlittenkupplungsteils an einem separaten Führungsschlitten möglich ist.The carriage coupling part is in the general case an integral part of the guide carriage. However, slot nuts are advantageously connected to the carriage coupling part, which engage in perpendicular to the displacement direction of a separate guide carriage extending T-shaped transverse grooves, whereby an adjustment of the position of the carriage coupling part on a separate guide carriage is possible.

Die Erfindung wird bezüglich eines vorteilhaften Ausführungsbeispiels näher erläutert mit:

  • Fig. 1 als Maschinenständer mit Maschinenkupplung zur Werkzeugmaschine im Längsschnitt
  • Fig. 2 als Schlittenkupplungsteil in Seitenansicht
  • Fig. 3 als Maschinenkupplungsteil mit Werkzeugmaschine in Seitenansicht
  • Fig. 4 als Werkzeugmaschine beim Einhängen in die Maschinenkupplung im Längsschnitt
The invention will be explained in more detail with respect to an advantageous embodiment with:
  • Fig. 1 as a machine stand with machine coupling to the machine tool in longitudinal section
  • Fig. 2 as a slide coupling part in side view
  • Fig. 3 as machine coupling part with machine tool in side view
  • Fig. 4 as a machine tool when hanging in the machine coupling in longitudinal section

Nach Fig. 1 weist ein (nur angedeuteter) Maschinenständer 2 eine Maschinenkupplung 1 zu einer (nur teilweise dargestellten) transportablen Werkzeugmaschine 3 in Form einer Kernbohrmaschine mit einer Drehachse A auf. An einem Führungsschlitten 4 mit einer Versetzungsrichtung V des Maschinenständers 2 ist ein Schlittenkupplungsteil 1a und ein angekoppelt zugeordnetes Maschinenkupplungsteil 1 b der Werkzeugmaschine 3 mit je einer zur Versetzungsrichtung V des Führungsschlittens 4 geneigten Spannfläche 5a, 5b angeordnet. Das an der Werkzeugmaschine 3 montierte Maschinenkupplungsteil 1b weist zwei umfänglich freiliegende Bolzen 6 auf, die hinter zwei koppelbar zugeordnete Haken 7a, 7b des Schlittenkupplungsteils 1a einhängbar sind. Der erste Haken 7a ist im Schlittenkupplungsteil 1a längs seiner Spannfläche 5a durch einen Exzentermechanismus versetzbar. Dabei ist der Exzentermechanismus selbst als ein in einer Zylinderhülse 8 geführter Exzenterbolzen 9 ausgebildet, der eine radial sprialförmige Kontaktfläche 10 aufweist, die auf einen federnd vorgespannt, schwenkbar gelagerten Schwenkhebel 11 drückt, an dem der erste Haken 7a ausgebildet ist. Der zweite Haken 7b ist am Schlittenkupplungsteil 1a starr festgelegt. Weiter sind mit dem Schlittenkupplungsteil 1a verspannbare Nutensteine 12 verbunden, die in senkrecht zur Versetzungsrichtung V des Führungsschlittens 4 verlaufende T-förmige Quernuten 13 eingreifen.To Fig. 1 has a (only hinted) machine stand 2 a machine coupling 1 to a (only partially shown) portable machine tool 3 in the form of a core drill with a rotation axis A. On a guide carriage 4 with a displacement direction V of the machine stand 2, a carriage coupling part 1a and a coupled machine coupling part 1b of the machine tool 3 are arranged, each with a direction of displacement V of the guide carriage 4 inclined clamping surface 5a, 5b. The machine coupling part 1b mounted on the machine tool 3 has two circumferentially exposed bolts 6 which can be hooked behind two hooks 7a, 7b of the carriage coupling part 1a that are coupled to one another. The first hook 7a is displaceable in the carriage coupling part 1a along its clamping surface 5a by an eccentric mechanism. In this case, the eccentric mechanism itself is designed as a guided in a cylinder sleeve 8 eccentric pin 9, which has a radially sprialförmige contact surface 10 which presses on a resiliently biased pivotally mounted pivot lever 11, on which the first hook 7a is formed. The second hook 7b is rigidly fixed to the carriage coupling part 1a. Further, with the carriage coupling part 1a braced sliding blocks 12 which engage in perpendicular to the displacement direction V of the guide carriage 4 extending T-shaped transverse grooves 13 engage.

Nach Fig. 2 weist der quer zur Versetzungsrichtung V (Fig. 1) längs seiner Exzenterachse E versetzbare Exzenterbolzen 9 eine aussen freiliegende Hebelaufnahme 14 in Form eines Innenvierkants zum Einstecken eines zugeordnet passenden Hebels 15 auf. Zudem sind sowohl an den Haken 7a, 7b des Schlittenkupplungsteils 1a als auch nach Fig. 3 an dem an der Werkzeugmaschine 3 montierten Maschinenkupplungsteil 1b beidseitig der beiden umfänglich freiliegende Bolzen 6 jeweils zwei gegeneinander orientierte Führungsflächen 16a, 16b ausgebildet, die senkrecht zu den Spannflächen 5a, 5b verlaufen.To Fig. 2 has the direction transverse to the displacement direction V ( Fig. 1 ) along its eccentric axis E displaceable eccentric pin 9 an externally exposed lever receptacle 14 in the form of a square socket for insertion of an associated matching lever 15. In addition, both on the hooks 7a, 7b of the carriage coupling part 1a and after Fig. 3 on the machine coupling part 1b mounted on the machine tool 3 on both sides of the two circumferentially exposed pins 6, two mutually oriented guide surfaces 16a, 16b are formed, which run perpendicular to the clamping surfaces 5a, 5b.

Nach Fig. 4 geschieht das Einhängen des Maschinenkupplungsteils 1b, das selbst weitgehend in die Werkzeugmaschine 3 eingelassen ist, indem die Werkzeugmaschine 3 von oben nach unten mit dem oberen Bolzen 6 zuerst in den zweiten Haken 7b eingehängt wird und dann mit einer Schwenkbewegung S auf die Spannfläche 5a des Schlittenkupplungsteils 1a geschwenkt wird. In einer (dargestellten) Einhängposition dreht sich dann der Schwenkhebel 11 gegen die Kraft einer Feder 17, bis der (zuvor herausgezogene) Exzenterbolzen 9 längs seiner Exzenterachse E (Fig. 2) seitlich in das Schlittenkupplungsteil 1a eingeschoben werden kann und mit seiner sprialförmigen Kontaktfläche 10 (Fig. 1) den Schwenkhebel 11 hintergreift. Damit ist die Werkzeugmaschine 3 fest aber noch nicht verspannt, was anschliessend durch die Drehung des Exzenterbolzens 9 geschieht.To Fig. 4 happens to hang the machine coupling part 1b, which is itself largely embedded in the machine tool 3 by the machine tool 3 is suspended from top to bottom with the upper pin 6 first in the second hook 7b and then with a pivoting movement S on the clamping surface 5a of the carriage coupling part 1a is pivoted. In a (shown) Einhängposition then the pivot lever 11 rotates against the force of a spring 17 until the (previously extracted) eccentric pin 9 along its eccentric axis E ( Fig. 2 ) can be inserted laterally into the carriage coupling part 1a and with its sprial-shaped contact surface 10 (FIG. Fig. 1 ) engages behind the pivot lever 11. Thus, the machine tool 3 is fixed but not yet braced, which is then done by the rotation of the eccentric pin 9.
