Description
Gegenstand der Erfindung ist ein Antrieb für den Sprin-gschlitten ariWerkzeugmaschinen zumHinterdrehen, Hinterfräsen oder Hinterschleifen von Werkstücken, insbesondere Wälzfräsern, mit umlaufender Nockenscheibe, deren Hub Über einen Stößel und einen Hebel mit einem einstellbaren Zwischenglied veränderlich auf den Springschlittenübertragbar ist.The subject of the invention is a drive for the sprint slide ari machine tools for back turning, back milling or back grinding of workpieces, in particular hobs, with a rotating cam disc, the stroke of which is via a ram and a lever with an adjustable link variably transferable to the jumping sled is.
Bei den bekannten Antrieben dieser Art ist die Veränderung der Hubhöhe unter Beibehaltung der Nockenscheibe oft mit umständlichen Einstellarbeiten verknüpft, welche für diese Umstellung eine lange Rüstzeit notwendig machen. Andere in kürzerer Zeit verstellbare Hi,nterdreheinr#chtungen sindini-hremAufbaurec,htverwickelt._ Diese Nachteile werden erfindungsgemäß leseitigt dadurch, daß der übertragungshebel zwischen ,der Nockenscheibe und dem Spriiigschlitfen doppelarmig ist und sein einer Arm am Springschlitten. angreift, w2hrend sein anderer Arm ein Gleitstück mit einer auf verschiedene Neigung zur Verschieberichtung des Stößels einstellbare ebene Schrägfläche trägt, auf die der Stößel einwirkt.In the known drives of this type, there is a change in the lifting height often associated with cumbersome adjustment work while retaining the cam disk, which require a long set-up time for this changeover. Others in shorter Time-adjustable hi, reverse turning devices are in-line with These disadvantages are read side according to the invention in that the transmission lever between, the cam and the Spriiigschlitfen is double-armed and its one Arm on the jump sled. attacks, while his other arm is a slider with a flat inclined surface adjustable to different inclinations to the slide direction carries on which the plunger acts.
Wahlweise kann naturgemäß auch die ne#gbare Gleitfläche an dem Stößel die an ihr anletifende Rolle am Doppelhebel angebracht sein. --. Optionally, of course, the inclinable sliding surface can also be attached to the plunger, and the roller that adjoins it can be attached to the double lever. -.
In weiterer Ausführung wird die Gleitfläche als Sehne eines kreisabschnittsförmigen ;Körpers ausgebildet, der im Kreismittelpunkt gelagert und dessen kreisförmiger Teil des Umfanges mit einer Verzahnung versehen ist, in die eine beispielsweise, ebenfalls am Doppelhebel gelagerte Schneckenwelle eingreift, welche ihren Antrieb von. einer von Hand drehbaren Schnecke mit Schneckenrad hält, welchin der Drehachse des Doppelhebels gelagert ist. Hierdurch ist die Möglichkeit gegeben, den, Sprung ,des Schlittens, jederzeit, auch während des Ganges ,der Maschine, -beliebig zu verändern.» In der Zeichnung ist ein Ausführungsbeispie1 der Erfindung in Verbindung mit einer Werkzeugmaschin e zum Hinterdrehen von Werkstücken, insbesondere Wälzfräsern, dargestellt.In a further embodiment, the sliding surface is designed as a chord of a segment of a circle ; Body formed, which is stored in the center of the circle and its circular Part of the circumference is provided with a toothing in which, for example, Also on the double lever mounted worm shaft engages, which their drive from. a manually rotatable worm with worm wheel, which holds in the axis of rotation of the double lever is mounted. This gives the opportunity to jump , of the slide, at any time, even while the machine is in motion change." In the drawing, an exemplary embodiment of the invention is in connection with a machine tool for back turning of workpieces, especially hobs, shown.
Auf der Welle 56, welche mit einerder Nutenzahl des zu bearbeitenden, Werkstückes entsprechenden Umlaufzahl angetrieben wird, sitzt--der Nocken,57. Er hebt bei jedem Umlauf einmal den StÖßel 74, welcher an einem seitlichen Arm eine Rolle75 trägt. Diese legt sich gegi#n, die gerade GleitfläChe 77 des in seinem Mittelpunkt auf einem Arm des Doppelhebels 76 gelagerten kreisabschnittsförmiggen GleitstÜckes 83, auf dessen, Kreisumfang eine Verzahnung angebracht ist. Der Doppelhebel 76 ist am Maschinenrähmen auf der Drehachse 79 schwenkbar gelagert. Sein oberer Hebelarm legt sich mit der Druckrolle 84 gegen eine Gleitfläche des Springschlittens 85b entgegen der Wirkung einer Feder 86. The cam 57 is seated on the shaft 56, which is driven with a number of revolutions corresponding to the number of slots on the workpiece to be machined. With each revolution it lifts the ram 74, which carries a roller 75 on a side arm. This lies against the straight sliding surface 77 of the sliding piece 83 in the form of a segment of a circle, which is mounted in its center on an arm of the double lever 76 and on the circumference of which a toothing is attached. The double lever 76 is pivotably mounted on the machine frame on the axis of rotation 79. Its upper lever arm rests with the pressure roller 84 against a sliding surface of the jumping slide 85b against the action of a spring 86.
-,Auf der Drehachse 79 des Doppelhebels ist ein (gestrichelt bezeichnetes) Handrad 78 gelagert, welches mittels Schnecke und Schneckenrad 8 1 über die--Schneckenwelle 8o die Schnecke 82 dreht, die, in die Verzahniffig -des Gleitstückes 83 eingreifend, die Neigung der Gleitfläche und damit den Hub des Häbels 76 v-erä#n-dert.' - -, On the axis of rotation 79 of the double lever a (dashed line) handwheel 78 is mounted, which by means of worm and worm wheel 8 1 on the - worm shaft 8o rotates the worm 82 , which engages in the teeth of the slider 83, the inclination of The sliding surface and thus the stroke of the lever 76 is changed.
