KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei der Metallbearbeitung, namentlich beim Ausarbeiten von Prägestanzen, Gesenken, sind an einem Werkstück oft mehrere Flächen zu bearbeiten, welche verschiedene Steigung zu einander haben, concave oder, convexe Form erhalten sollen und dergl.In metalworking, especially when working out embossing punches, dies, are Often several surfaces to be machined on a workpiece, which have different slopes should have one another, should have a concave or convex form, and the like.
Bei Benutzung der jetzt im Gebrauch befindlichen Maschinen können solche Flächen ohne Umspannung des Werkstückes nicht hergestellt werden.When using the machines now in use, such surfaces cannot be produced without reclamping the workpiece.
Die vorliegende Einrichtung hilft diesem Uebelstande ab.The present device remedies this problem.
Fig. ι der Zeichnung stellt einen Schnitt durch die Vorrichtung dar.Fig. Ι of the drawing shows a section through the device.
Fig. 2 zeigt eine Oberansicht mit Schnitt durch die Kugel.Fig. 2 shows a top view with a section through the ball.
Fig. 3 ist ein Schnitt durch den Lagerkörper, die Kugel in Ansicht.Fig. 3 is a section through the bearing body, the ball in view.
Fig. 4 ist ein halber Querschnitt.Fig. 4 is a half cross section.
Fig. 5 zeigt in vergröfsertem Mafsstabe die Festspannvorrichtung.Fig. 5 shows the clamping device on an enlarged scale.
Fig. 6 zeigt einen Schnitt durch die Vorrichtung mit geneigter Arbeitsfläche.6 shows a section through the device with an inclined work surface.
Die Aufspannvorrichtung besteht zunächst aus einer Platte a, auf welche das zu bearbeitende Werkstück in bekannter Weise aufgespannt wird.The jig initially consists of a plate a on which the workpiece to be machined is clamped in a known manner.
Die Platte läuft unten in eine mit derselben aus einem Stück bestehende oder abnehmbare Kugel b aus, welche in einem mit Supportführung versehenen Kugellager d liegt; auch die letztere kann mit dem Körper aus einem Stück hergestellt werden oder abnehmbar sein.The plate runs out at the bottom into a ball b consisting of one piece or removable, which lies in a ball bearing d provided with a support guide; the latter can also be made in one piece with the body or it can be detachable.
Durch die Mitte der Kugel geht ein Bolzen h mit Schraube s1, welche mit einer Mutter m festgezogen werden kann. A bolt h with screw s 1 , which can be tightened with a nut m, goes through the center of the ball.
Diese prismatische Mutter führt sich in so langen schwalbenschwanzförmigen Schlitzen n, als für die Bewegung der Kugel beabsichtigt wird.This prismatic nut is guided in dovetail-shaped slots n as long as is intended for the movement of the ball.
Durch Anziehen der Schraube s1 wird die prismatische Mutter m in dem schwalbenschwanzförmigen Schlitz η festgeklemmt (Fig. 5) und hierdurch die Kugel b in der betreffenden Lage festgestellt.By tightening the screw s 1 , the prismatic nut m is clamped in the dovetail-shaped slot η (FIG. 5) and the ball b is thereby fixed in the relevant position.
Ist die Kugel mit der Platte durch Anziehen der Schraube in der gewünschten Steigung festgestellt, so läfst sie sich durch Hand oder Schneckengetriebe noch um ihre Achse bewegen. Once the ball has been fixed to the plate by tightening the screw at the desired pitch, so it can still be moved around its axis by hand or worm gear.
Zu diesem Behuf ist die Kugel am Umfange mit Schraubengewinde versehen, in welches die Schnecke g eingreift.For this purpose, the circumference of the ball is provided with a screw thread into which the worm g engages.
Um jede gewünschte Steigung und Stellung zu erzielen, sind die schwalbenschwanzförmigen Schlitze η am unteren Lager der Kugel als Kreuzschlitze angeordnet, so dafs durch Bewegen der Kugel in den Schlitzen die Arbeitsfläche nach vier Seiten geneigt werden kann, während durch das Schneckengetriebe eine Bewegung um die Achse erfolgt.In order to achieve any desired incline and position, the dovetail-shaped slots η on the lower bearing of the ball are arranged as cross slots, so that by moving the ball in the slots the work surface can be inclined to four sides, while the worm gear causes a movement around the axis he follows.
Durch Support mit Rundbewegung kann eine weitere Drehung erfolgen.A further rotation can take place by means of a support with a circular movement.
Die Kugel wird in der gewünschten Stellung durch einen getheilten Ring festgespannt, welcher durch Ringsegmente, Spanneisen, Druckschraube s oder sontwie ersetzt werden kann.The ball is clamped in the desired position by a split ring, which can be replaced by ring segments, clamping irons, pressure screws s or other.
Durch Drehen der Kugel in ihrem Lager und um ihre Achse ist man in der Lage, je nach der Stellung des Arbeitsfraisers nur durch Drehen der Kurbel concave und convexe Kegelflächen herzustellen. Man kann aufserdemBy turning the ball in its bearing and around its axis one is able to ever after the position of the worker, only by turning the crank concave and convex To produce conical surfaces. One can also
bei Benutzung einer λ Bohrmaschine schiefe Löcher in Kreis- oder Curvenstellung bohren.when using a λ drill, drill oblique holes in a circle or curve position.
