Description
Gegenstand der Erfindung ist eine Verbesserung der Kopiervorrichtung gemäß Patent 326103 und unterscheidet sich von dieser dadurch, daß der schwingbar angeordnete Werkzeughalter sowohl einen verschiebbaren Drehstahl als auch einen Abstechstahl trägt, der beim Ausschwingen des Werkzeughalters in Tätigkeit tritt.The invention is an improvement of the copying device according to Patent 326103 and differs from this in that the oscillating Tool holder carries both a sliding turning tool and a parting tool, which comes into action when the tool holder swings out.
In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung in Seitenansicht teilweise geschnitten dargestellt.In the drawing, an example embodiment of the invention is in side view shown partially cut.
Wie bei Patent 326103 ist auf dem Bett der Drehbank der Werkzeugschlitten b angeordnet, welcher den schwingbaren Werkzeughalter e trägt. Das freie Ende der Schablone g wird in einer Ausnehmung des Armes m geführt, der mit dem Werkzeugschlitten b aus einem Stück bestehen oder, wie in der Zeichnung angegeben, mit einer vom Schlitten b abnehmbaren Konsole η verbunden sein kann. An dieser Konsole η ist ein Handhebel d drehbar gelagert, welcher am unteren Ende mit einer Ausnehmung 0 versehen ist, in welche ein Zapfen oder Gleitstück p eines Werkzeugschlittens q hineingreift, der zur Aufnahme des Drehstahles i dient. Dieser Werkzeugschlitten q gleitet in dem Werkzeughalter e. Gehalten wird der Drehstahl i' in dem Werkzeugschlitten q durch eine oder mehrere Spannschrauben r. Um jedoch den Drehstahl i vor- und rückwärts bewegen zu können, besitzt der Werkzeughalter e an der Stelle, an welcher der Werkzeugschlitten q Spannschrauben trägt, eine in Richtung der Drehstahlbewegung sich erstreckende Aussparung s.As in patent 326103, the tool slide b is arranged on the bed of the lathe and carries the swingable tool holder e. The free end of the template g is guided in a recess of the arm m , which can consist of one piece with the tool slide b or, as indicated in the drawing, can be connected to a bracket η which can be removed from the slide b. A hand lever d is rotatably mounted on this bracket η , which is provided at the lower end with a recess 0 into which a pin or slide p of a tool slide q engages, which is used to hold the turning tool i . This tool slide q slides in the tool holder e. The turning tool i 'is held in the tool slide q by one or more clamping screws r. However, in order to be able to move the turning tool i back and forth, the tool holder e has a recess s extending in the direction of the turning tool movement at the point at which the tool slide q carries clamping screws.
Gleichzeitig trägt der Werkzeughalter e At the same time, the tool holder e
an seinem unteren Ende einen in geeigneter Weise befestigten Abstechstahl t, welcher durch Ausschwingen des Werkzeughalters e mittels eines Hebels u in Tätigkeit tritt. Dieser Hebel u dient gleichzeitig zur Feststellung des Werkzeughalters, solange der Drehstahl in Tätigkeit ist.at its lower end a parting tool t fastened in a suitable manner, which comes into action by swinging the tool holder e by means of a lever u. This lever u also serves to fix the tool holder as long as the turning tool is in operation.
Mit dem Handhebel d auf gemeinschaftlicher Drehachse sitzt fest der Taster /, dessen Gleitbahn, mit welcher er an der Schablone entlanggleitet, nach einer Kurve gekrümmt ist.With the hand lever d on the common axis of rotation, the pushbutton / is firmly seated, the sliding track of which it slides along the template is curved according to a curve.
An Stelle einer Zugfeder ist hier ein gewichtbelasteter Hebel ν vorgesehen, welcher das Bestreben hat, den Handhebel in Richtung des Pfeiles zu ziehen, wodurch der Taster / eine innige Berührung mit der Schablone g erhält. Bei Vorwärtsbewegung des Werkzeugschlittens b beschreibt wie im Hauptpatent der Drehstahl i an dem Werkstück / eine Kurve, die genau der Form der Schablone entspricht.Instead of a tension spring, a weight-loaded lever ν is provided here, which tends to pull the hand lever in the direction of the arrow, whereby the button / gets intimate contact with the template g. When the tool slide b moves forward, as in the main patent, the turning tool i on the workpiece / describes a curve that corresponds exactly to the shape of the template.
Sobald jedoch das Werkstück die gewünschte Form erhalten hat, wird durch Anheben des Hebels u der mit dem letzteren verbundene Werkzeughalter e ausgeschwungen und der Drehstahl i ausgerückt.However, as soon as the workpiece has obtained the desired shape , the tool holder e connected to the latter is swung out by lifting the lever u and the turning tool i is disengaged.
Da jedoch auch der Abstechstahl t in dem schwingenden Werkzeughalter e befestigt ist, so tritt bei Ausrücken des Drehstahles i der Abstechstahl t in Tätigkeit, der das Abtrennen des fertigen Werkstückes von dem Stangenmaterial bewirkt.However, since the parting tool t is also fastened in the oscillating tool holder e , when the turning tool i is disengaged, the parting tool t comes into operation, which causes the finished workpiece to be separated from the bar material.
