Die Erfindung bezieht sich auf eine Nachformfräseinrichtung in Form eines Zusatzgerätes zum Anbau an eine Bohr- oder Fräsmaschine, wobei der Antrieb für den Fräser von der Bohr- oder Fräsmaschine ableitbar ist.The invention relates to a reshaping milling device in the form of an additional device for attachment to a drilling or milling machine, whereby the drive for the milling cutter can be derived from the drilling or milling machine is.

Solche Nachformfräseinrichtungen sind bekannt (DE-GM 19 65 035), sie werden auf dem Tisch einer Bohr- oder Fräsmaschine in Form eines seitlich bewegbaren Parallelogrammes angebaut. In Verbindung mit einer Heimwerkerbohrmaschine, die bekanntlieh keinen Maschinentisch besitzt, ist eine solche Nachformfräseinrichtung jedoch nicht verwendbar.Such Nachformfräseinrichtungen are known (DE-GM 19 65 035), they are one on the table Drilling or milling machine attached in the form of a laterally movable parallelogram. In connection with a do-it-yourself drill, which is known to have no machine table, is such a thing Post-form milling device, however, cannot be used.

Es ist Aufgabe der Erfindung, eine Nachformfräseinrichtung als Zusatzgerät zu Heimwerkerbohrmaschinen zu schaffen. Dies wird erfindungsgemäß dadurch erreicht, daß die Nachformfräseinrichtung zum Anbau an eine Heimwerkerbohrmaschine als Pantograph ausgebildet ist, dessen Systemhauptachse mit ihrem einen Ende an der Spindel der Heimwerkerbohrmaschine befestigbar ist und die gleichzeitig als Antriebswelle für den Fräser dient, wozu sie mit ihrem anderen Ende über Antriebsübertragungseinrichtungen mit dem Fräser in Antriebsverbindung steht.It is the object of the invention to provide a post-form milling device as an additional device for do-it-yourself drills to accomplish. This is achieved according to the invention in that the reshaping milling device for attachment is designed as a pantograph on a do-it-yourself drill, the system main axis of which with its one end can be attached to the spindle of the do-it-yourself drill and at the same time as a drive shaft serves for the milling cutter, for which purpose it is connected to the milling cutter with its other end via drive transmission devices is in drive connection.

Hierdurch können bei Heimwerkerbohrmaschinen diese zur Halterung und zum Antrieb von Kopiervorrichtungen in Form von Pantographen verwendet werden, wozu deren Hauptachse am senkrechten oder waagerechten Antriebswellenende der Bohrmaschine befestigbar ist. Hierzu kommt die lösbare Befestigung des Pantographen dadurch erfolgen, daß, wie an sich bekannt, die Hauptachse als Antriebswelle mittels Anschlußkegel am Spindelende der Bohrmaschine vsrspannt und auf dieser sodann das Drehlager als Träger der Kopiervorrichtung drehbar sitzt, wobei das austretende Wellenende dem Antrieb des Kopierfräsers dient.As a result, in do-it-yourself drills, these can be used to hold and drive copier devices be used in the form of pantographs, including their main axis on the vertical or horizontal drive shaft end of the drill can be attached. This is where the detachable attachment comes in of the pantograph take place in that, as is known per se, the main axis as a drive shaft by means of Connection cone on the spindle end of the drill vsrspannt and on this then the pivot bearing as Carrier of the copying device is rotatably seated, the exiting shaft end being the drive of the copying cutter serves.

Nach der DE-OS 21 10 574 ist nämlich eine Radienfräsvorrichtung bekannt, welche in gleicher Weise an der Spindel einer Bohr- oder Fräsmaschine ansetzbar ist und bei der auch der Fräserantrieb in gleicher Weise von der Bohr- bzw. Frässpindel ableitbar ist.According to DE-OS 21 10 574 namely a radius milling device is known which in the same Way can be attached to the spindle of a drilling or milling machine and in which the cutter drive in can be derived in the same way from the drilling or milling spindle.

Ausführungsformen von Nachformfräseinrichtungen gemäß der Erfindung sind beispielsweise in der Zeichnung dargestellt, und zwar zeigtEmbodiments of Nachformfräseinrichtungen according to the invention are for example in Drawing shown, namely shows

F i g. 1 und 2 die Vorderansicht und Draufsicht einer Parallelogramm-Pantographenausführung bei senkrechter Antriebsspindel,F i g. 1 and 2 show the front view and top view of a parallelogram pantograph design in a vertical position Drive spindle,

F i g. 3 und 4 die Vorderansicht und Draufsicht einer Parallelogramm-Pantographenausführung bei waagerechter Antriebsspindel.F i g. 3 and 4 the front view and top view of a parallelogram pantograph design with a horizontal one Drive spindle.

Beim ersten Ausführungsbeispiel nach F i g. 1 und 2 ist an der Antriebsspindel 21 einer Heimwerkerbohrmaschine, welche senkrecht über einem Tisch 22 angeordnet ist, die Systemwelle 23 eingespannt. Diese (23) trägt über das Zwischenlager 24 einen Parallelogramm-Pantographen 25 mit Taster 26 und Fräser 27, welch letzterer (27) mittels Umlenk- und Übersetzungstrieb und -Riemen 28, 29 von der Antriebsspindel 21 betrieben wird. Wird nun, wie bei Pantographen üblich, mit dem Taster 26 eine Schablonenkurve S nachgefahren, so erzeugt der Fräser 27 am Werkstück 30 hier eine verkleinerte Kopie. Die Verkleinerung oder Vergrößerung ist durch Verstellung der Hebel zueinander einstellbar. Wie ersichtlich, ist diese Anordnung in einfacher Weise an stationär eingespannten Heimwerkerbohrmaschinen als Zusatzgerät anbringbar.In the first embodiment according to FIG. 1 and 2, the system shaft 23 is clamped on the drive spindle 21 of a do-it-yourself drill, which is arranged vertically above a table 22. This (23) carries a parallelogram pantograph 25 with button 26 and milling cutter 27 via the intermediate storage 24, the latter (27) being operated by the drive spindle 21 by means of deflection and translation drives and belts 28, 29. If, as is usual with pantographs, a template curve S is followed with the button 26, the milling cutter 27 generates a reduced copy on the workpiece 30 here. The reduction or enlargement can be adjusted by adjusting the levers in relation to one another. As can be seen, this arrangement can be attached in a simple manner to stationary do-it-yourself drills as an additional device.

Das zweite Ausführungsbeispiel nach F i g. 3 und 4 zeigt hiergegen eine Antriebsspindel 31 einer Heimwerkerbohrmaschine, welche waagerecht zu einem Tisch 32 angeordnet ist, wobei an der Antriebsspindel 31 die Systemwelle 33 eingespannt ist. Die Systemwelle 33 trägt sodann über das Zwischenlager 34 mit Winkelstück 34a und Winkelwelle 33a wiederum einen Parallelogramm-Pantographen 35 mit Taster 36 und Fräser 37, welch letzterer (37) mittels Umlenk- und Übersetzungstrieb und -Riemen 38, 39 von der Antriebsspindel 31 betrieben wird.The second embodiment according to FIG. 3 and 4 show, on the other hand, a drive spindle 31 of a do-it-yourself drill, which is arranged horizontally to a table 32, with the drive spindle 31 the system shaft 33 is clamped. The system shaft 33 then carries over the intermediate bearing 34 with an angle piece 34a and angled shaft 33a in turn a parallelogram pantograph 35 with button 36 and Milling cutter 37, which the latter (37) by means of deflection and translation drive and belts 38, 39 from the Drive spindle 31 is operated.

Wird nun, wie bei Pantographen üblich, mit dem Taster 36 eine Schablonenkurve 8 nachgefahren, so erzeugt der Fräser 37 am Werkstück 40 eine verkleinerte Kopie, wobei hier in der Pantographenebene und durch zusätzliche Verschwenkungsmöglichkeit des Winkelstücks 34a um die Achse A-A auch räumlich kopiert werden kann.If, as is usual with pantographs, a template curve 8 is traced with the button 36, the milling cutter 37 generates a reduced copy on the workpiece 40, whereby here in the pantograph plane and through the additional possibility of pivoting the angle piece 34a about the axis AA, it is also possible to copy spatially .
