Description

Die Erfindung bezieht sich auf die bekannten elektromotorisch angetriebenen Fräsketten-Stemmmaschinen für Zimmereibetriebe, bei denen der Antriebselektromotor auf zwei lotrechten Säulen eines auf den Balken aufsetzbaren Maschinenfußes geführt ist. Das Ausstemmen oder Fräsen des im Balken erforderlichen Schlitzes erfolgt durch Niederdrücken des Motors, wobei die Fräskette in das Balkenholz eindringt. Es ist bekannt, bei diesen Maschinen den beweglichen Maschinenteil, also insbesondere den Motor, federnd abzustützen, was bei einer bekannten Ausführung durch einen Stützhebel geschah, der im Maschinenfuß vorn drehbar gelagert war und der sich schräg nach oben und hinten erstreckte, wobei unterhalb des Motors eine Abstützrolle angeordnet war, die mit dem freien Ende des Stützhebels zusammenarbeitete.The invention relates to the known electric motor driven Milling chain mortising machines for carpentry businesses where the drive electric motor guided on two vertical columns of a machine base that can be placed on the beam is. The required slot in the beam is chiseled out or milled through Depressing the motor, whereby the milling chain penetrates the timber. It is known, in these machines, the moving machine part, so in particular the Motor to be resiliently supported, which in a known embodiment by a support lever happened, which was rotatably mounted in the front of the machine base and which is sloping afterwards extending above and behind, with a support roller arranged below the motor that cooperated with the free end of the support lever.

Diese bekannte Ausführung hat den Nachteil, daß die Abstützung außerhalb der Schwerpunktsebene des beweglichen Maschinenteils erfolgte und daß infolgedessen beim Arbeiten eine erhöhte Reibung an den Gestellsäulen auftrat, daß eine größere von der Hand des Zimmermanns auszuübende Kraft erforderlich war und daß die Maschine leicht zum Kippen neigte.This known design has the disadvantage that the support outside the center of gravity plane of the movable machine part took place and that as a result When working, there was increased friction on the frame columns that greater force to be exerted by the hand of the carpenter was required and that the machine tended to tip over.

Dieser Nachteil ist erfindungsgemäß dadurch vermieden worden, daß der im Maschinenfuß drehbar gelagerte und federbeeinflußte Stützhebel den heb- und senkbaren Maschinenteil in seiner Schwerpunktsebene abstützt. Bei der Stützhebelanordnung gemäß der Erfindung liegt der Drehpunkt des Stützhebels hinter den Führungssäulen in dem rückwärtigen Ende des Maschinenfußes.This disadvantage has been avoided according to the invention in that the spring-controlled support lever, which is rotatably mounted in the machine base, controls the lifting and lowerable machine part is supported in its center of gravity plane. With the support lever arrangement according to the invention the fulcrum of the support lever lies behind the guide columns in the rear end of the machine foot.

Die Bewegung der Maschine ist dadurch wesentlich erleichtert worden. Ein gefühlvolles Anfahren gegen das Werkstück ist nunmehr möglich, und die Neigung zum Auftreten von Kettenbrüchen ist ganz erheblich herabgemindert worden. Durch den verminderten Gegendruck beim Niederdrücken der Fräskette entsteht eine geringere Haftwirkung auf dem Werkstück, so daß sich der Querzug der Fräskette besser auswirken kann. Das hat zur Folge, daß der bekannte, an der Maschine befindliche Seitenanschlag stets gut zur Anlage kommt. Das Entstehen ungewollter gestaffelter Balkenlöcher wird dadurch vermieden. Die Führungssäulen des Gestells sind geringerer Abnutzung ausgesetzt, so daß sie beispielsweise nunmehr aus ungehärtetem Werkstoff bestehen können.The movement of the machine has been made much easier as a result. A sensitive approach against the workpiece is now possible, and the inclination the occurrence of continued fractions has been reduced quite considerably. By the reduced counterpressure when pressing down the milling chain results in a lower one Adhesive effect on the workpiece, so that the transverse pull of the milling chain has a better effect can. This has the consequence that the well-known, located on the machine side stop always comes to the plant. The emergence of unwanted staggered beam holes is thereby avoided. The guide pillars of the frame are less subject to wear exposed, so that they now consist of uncured material, for example can.

In der Zeichnung ist eine Fräsketten-Stemmmaschine nach der Erfindung in einem Ausführungsbeispiel von der Seite gesehen dargestellt, wobei alle hier nicht interessierenden lUaschinenteile weggelassen sind.In the drawing is a milling chain mortising machine according to the invention shown in one embodiment seen from the side, all here Machine parts that are not of interest have been omitted.

Der Maschinenfuß i, der beispielsweise als Hohlgehäuse ausgebildet ist, trägt vorn die beiden lotrechten Führungssäulen 2, auf denen der Antriebselektromotor 3 samt Fräskettenführung und Fräskette mittels der Hülsen 4 heb- und senkbar geführt ist. Der Stützhebel 5 ist um die im Fuß i hinten liegende Achse 6 drehbar, und sein freies Ende arbeitet in an sich bekannter Weise mit einer unten am Motorgehäuse befestigten Stützrolle 7 zusammen. Die Stützrolle 7 liegt in der Schwerpunktsebene des beweglichen Maschinenteils 3, 4. Im Maschinenfuß sind eine oder zwei Zugschraubenfedern 8 angeordnet, die einerseits an einem festen Bolzen 9 und andererseits an den Enden 5' des Stützhebels angreifen.The machine base i, which is designed, for example, as a hollow housing is, the front carries the two vertical guide columns 2, on which the drive electric motor 3 including the milling chain guide and milling chain can be raised and lowered by means of the sleeves 4 is. The support lever 5 is rotatable about the axis 6 located at the rear in the foot i, and its free end works in a manner known per se with a bottom on the motor housing attached support roller 7 together. The support roller 7 lies in the plane of the center of gravity of the moving machine part 3, 4. There are one or two tension coil springs in the machine base 8 arranged on the one hand on a fixed bolt 9 and on the other hand at the ends Engage 5 'of the support lever.
