Description

Elektromotorisch angetriebene Elektroerosionsmaschine, welche zur Herstellung von Werkstücken mit Durchbrüchen oder Aussparungen mit beliebigen Profilen dient Die Erfindung bezieht sich auf eine elektromotorisch angetriebene Elektroe.rosionsmaschine, welche zur Herstellung von Werkstücken mit Durchbrüchen oder Aussparungen mit beliebigen Profilen dient. Solche Elektroerosionsmaschinen sind mit verschiedenen komplizierten Getrieben versehen, und zwar mit je einer Vorschubeinrichtung für die Erosionselektrode und für den Erosionselektrodenhalter sowie mit einer Kopiereinrichtung zur Übertragung der herzustellenden Form von einer Musterkurve auf die Erosionselektrode und mit einer Antriebseinrichtung für eine Drehbewegung des Erosionselektrodenhalters. Die Elektroerosionsmaschinen haben daher einen verwickelten *Aufbau und beanspruchen entsprechend viel Platz.Electric discharge machine driven by an electric motor, which is used for Production of workpieces with openings or recesses with any profile The invention relates to an electric motor driven electrical discharge machine, which for the production of workpieces with openings or recesses with any Profiles is used. Such electrical discharge machines are complicated with various Provided with gears, each with a feed device for the erosion electrode and for the erosion electrode holder and with a copier for transferring the shape to be produced from a sample curve to the erosion electrode and with a drive device for a rotary movement of the erosion electrode holder. the EDM machines therefore have an intricate * structure and are demanding accordingly a lot of space.

Die Erfindung vermeidet diese Nachteile dadurch, daß ein Antriebsmotor mit zwei Antriebsorganen vorgesehen ist, von denen eins die Kopiereinrichtung und die Vorschubeinrichtung für die axiale Verstellung des Erosionselektrodenhalters und das andere die Antriebseinrichtung für die Drehbewegung des Erosionselektrodenhalters um seine Achse antreibt. Durch diese Erfindung wird eine Elektroerosionsmaschine geschaffen, welche in gedrängter Anordnung sämtliche erforderlichen Getriebe enthält und nur von einem einzigen Elektromotor angetrieben wird.The invention avoids these disadvantages in that a drive motor is provided with two drive elements, one of which is the copier and the feed device for the axial adjustment of the erosion electrode holder and the other the drive device for the rotational movement of the erosion electrode holder drives around its axis. This invention provides an electrical discharge machine created, which contains all the necessary gear in a compact arrangement and is only powered by a single electric motor.

Ein Ausführungsbeispiel der Erfindung ist in der Figur schematisch dargestellt, bei welchem ein schlangenlinienförmiges Profil 1 nach einer Schablone 13 hergestellt werden soll. Die Elektrode 2 wird über einen zweiarmigen Hebel 3, die Verbindungsstange 4 über den Zahnstangenteil 5 und die Zahnräder 6, 7 sowie das Zahnsegment 8 mit dem Hebel 9 angetrieben, an dessen Ende 10 ein Taster 11 angelenkt ist, der die Kurve 12 der Schablone 13 abtastet, welche in Richtung 14 hin- und herbewegt werden kann. Zum Antrieb des Bohrkopfes 15 dient ein Zahngetriebe 16 für die Auf- und Abwärtsbewegung des Bohrkopfes und ein Zahngetriebe 17 für die Erzeugung der Drehbewegung des Bohrkopfes um seine senkrechte Achse. Die Maschine wird von einem Motor 18 angetrieben, der über ein Zahnrad 19 und die Zahnung 20 der Schablone 13 diese und über die Kegelräderpaare 21, 22, 23 das Zahnrad 24 des Zahngetriebes 17 antreibt. Das Zahnrad 25 des Zahngetriebes 16 wird von einer Zahnung 26 der Schablone 13 angetrieben. Entsprechend der Bewegung des Hebelarmes 9 in Pfeilrichtung 27 beim Abtasten der Kurve 12 der Schablone 13 wird die Elektrode 2 in proportionaler Weise waagerecht bewegt. Die einzelnen Glieder zur Übertragung dieser Bewegungen können so gestaltet sein, daß die Bewegungen im Verhältnis 1:1 oder aber auch in einem anderen Verhältnis, z. B. größer oder kleiner, übertragen werden.An embodiment of the invention is shown schematically in the figure shown, in which a serpentine profile 1 according to a template 13 is to be produced. The electrode 2 is operated by a two-armed lever 3, the connecting rod 4 via the rack part 5 and the gears 6, 7 as well the toothed segment 8 is driven by the lever 9, at the end 10 of which a button 11 is articulated which scans the curve 12 of the template 13 which reciprocates in the direction 14 can be moved. To drive the drill head 15, a toothed gear 16 is used for the up and down movement of the drill head and a toothed gear 17 for the generation the rotary movement of the drill head around its vertical axis. The machine is powered by a motor 18 driven by a gear 19 and the teeth 20 of the template 13 these and via the bevel gear pairs 21, 22, 23 the gear 24 of the gear mechanism 17 drives. The gear 25 of the gear mechanism 16 is of a toothing 26 of the template 13 powered. Corresponding to the movement of the lever arm 9 in the direction of arrow 27 at Scanning the curve 12 of the template 13 becomes the electrode 2 in a proportional manner moved horizontally. The individual limbs for the transmission of these movements can be designed so that the movements in a ratio of 1: 1 or in one other ratio, e.g. B. larger or smaller, are transmitted.
