Description
Zahnradstoßmaschine mit in Richtung einer Längsachse in einer Büchse hin und her gehenden ' und um diese Achse sich drehenden Stößeln Um das Abhebendes Werkzeugs -von dem Werkstück bei Zahnradstoßmaschinen mit Zahnschneidrad zu bewirken, hat man bereits Einrichtungen angeordnet, bei denen der gesamte Stößelträger mit Spindel und Stößelrad verschwenkt wird. ' Hierbei ist der Nachteil vorhanden, daß verhältnismäßig große XIassen in Schwingungen versetzt werden müssen. Dieser Nachteil ist beim Erfindungsgegenstand dadurch beseitigt, daß der oder die Stößel außermittig in ihren Büchsen geführt sind, die zum Abheben und Einstellen des Stößels auf dein Rückhub bzw.Arbeitshub hin und her schwingbar sind.Gear shaping machine with in the direction of a longitudinal axis in a sleeve reciprocating 'and around this axis rotating plungers around the lifting point Tool from the workpiece in gear shaping machines with gear cutting wheels, one has already arranged facilities in which the entire slide carrier with Spindle and ram is pivoted. The disadvantage here is that relatively large XIassen must be made to vibrate. This disadvantage is eliminated in the subject matter of the invention in that the plunger or plungers are eccentric are guided in their sleeves, which are used to lift and adjust the plunger on your Return stroke or working stroke can be oscillated back and forth.
Durch diese Bauweise 'sind die hin und her schwingenden Massen klein. Außerdem wird hierdurch das Werkzeug zum Werkstück in bequemer Weise in die richtige Lage gebracht, die besonders wichtig bei Mehrspindelmaschinen ist. Es können durch diese Einrichtung kleine Maßunterschiede von 1/,o und i/ioo mm eingestellt werden, um die Zahntiefe zu vergrößern oder zu verringern. Diese Änderungen sind besonders bei Zwei- oder Mehrspindelmaschinen notwendig.This design means that the masses oscillating back and forth are small. In addition, this makes the tool for the workpiece conveniently in the correct position Position that is particularly important in multi-spindle machines. It can get through this device allows small differences in dimensions of 1 /, o and i / 100 mm to be set, to increase or decrease the tooth depth. These changes are special necessary for two- or multi-spindle machines.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in den F ig. i und -a der Zeichnung dargestellt.An exemplary embodiment of the subject matter of the invention is shown in FIGS. i and -a shown in the drawing.
Fig. z zeigt den Spindelstock einer Zweispindelstoßmaschine im Schnitt.Fig. Z shows the headstock of a two-spindle slotting machine in section.
Fig.2 stellt einen Schnitt nach der Linie 11-II der Fig. T dar.FIG. 2 shows a section along the line 11-II of FIG.
Im Stößelträger i der :Maschine liegen, drehbar gelagert und axial nach beiden Seiten festgelegt, die Büchsen 2 und 2a. Die Büchsen führen in ihren exzentrischen Bohrungen die Stößelspindeln 3 und 3a mit den Schneidrädern .4 und 41 1, in bekannter Weise die Hub- und die rotierenden Abwälzbewegungen ausführen. Dabei erfolgt der Antrieb der Spindeln in bekannter Weise.In the ram carrier i of the: machine lie, rotatably mounted and axially fixed on both sides, the sleeves 2 and 2a. The cans lead in theirs eccentric bores the ram spindles 3 and 3a with the cutting wheels .4 and 41 1, the lifting and rotating rolling movements in a known manner carry out. The spindles are driven in a known manner.
An den Büchsen :2 sind Schwenkhebel 5 und 511 angeordnet, an welchen die Stoßstangen 6 und 6a angelenkt sind.On the sleeves: 2 pivot levers 5 and 511 are arranged on which the bumpers 6 and 6a are hinged.
Bei Verdrehung der Büchsen 2 und 2a mittels der Stoßstangen 6 und 611 im Uhrzeigersinne schwingen die Mittelpunkte 7 und 7a der Stößelspindeln 3, 3a um die Mittelpunkte 8 und 8a der Büchsen. Demzufolge rücken die Stößel bzw. ihre Schneidräder 4,4!' vom Werkstück g um einen bestimmten Betrag ab, und zwar in der Größe entsprechend dem Ausschlagswinkel der Hebel 5 und 5a.When the bushes 2 and 2a are rotated by means of the bumpers 6 and 611 the center points 7 and 7a of the ram spindles 3 swing clockwise, 3a around the centers 8 and 8a of the sleeves. As a result, move the plunger or their Cutting wheels 4,4! ' from the workpiece g by a certain amount, namely in the Size according to the angle of deflection of levers 5 and 5a.
Die Exzenterbüchsen 2 und 2a der Stößelspindeln 3 und 3a können so eingestellt werden, daß deren Abheb- und Zustellbewegungen zum Werkstück immer in Richtung der Verbindungslinien io und ioa vom Mittelpunkt des Werkzeuges 7, 7a bzw. Stößels zum Mittelpunkt i i bzw. i ja des Werkstückes erfolgen. Dabei ist zu berücksichtigen, daß je nach dem Werkstückdurchmesser sich die Richtungen der Mittelpunktsverbindungslinien io und ioa verändern. Dementsprechend wird die Ausgangsstellung der Schwenkhebel s und 511 für ihre Ausschlagbewegung eingestellt. Die Ausschlagbewegung der Schwenkhebel und damit der Exzenterbüchsen 2 und 2a erfolgt jeweils im unteren und oberen Ende der Hubbewegungen des Stößels. Das Bewegen der Hebel kann mechanisch, elektrisch oder hydraulisch erfolgen.The eccentric bushes 2 and 2a of the ram spindles 3 and 3a can be adjusted so that their lifting and infeed movements to the workpiece are always in the direction of the connecting lines io and ioa from the center of the tool 7, 7a or ram to the center ii and i ja of the workpiece take place. It must be taken into account that the directions of the midpoint connecting lines io and ioa change depending on the workpiece diameter. The starting position of the pivot levers s and 511 is set accordingly for their deflection movement. The deflection movement of the pivot levers and thus the eccentric bushings 2 and 2a takes place in the lower and upper end of the stroke movements of the plunger. The levers can be moved mechanically, electrically or hydraulically.
In dem dargestellten Ausführungsbeispiel könnte die Schrupparbeit z. B. von dem Stößel n und die Schlichtarbeit von dem Stößel 3a übernommen werden.In the illustrated embodiment, the roughing work could z. B. be taken over by the plunger n and the finishing work by the plunger 3a.
