Die vorliegende Erfindung betrifft eine Hilfsvorrichtung für Drehbänke, bei welcher das zu bearbeitende Arbeitsstück oder das Werkzeug unter jedem beliebigen Winkel eingestellt werden kann dadurch, daß an einem auf dem Support drehbar angeordneten Pfeiler ein Bügel in senkrechter Richtung verschiebbar angeordnet ist, der seinerseits einen um die Horizontalachse drehbaren SpindelhalterThe present invention relates to an auxiliary device for lathes in which the workpiece or tool to be machined is set at any angle can be achieved in that a bracket can be displaced in the vertical direction on a pillar rotatably arranged on the support is arranged, which in turn has a spindle holder rotatable about the horizontal axis

ίο trägt, in welchem wieder eine auch um die horizontale Achse drebare Hülse sich befindet, welche zur Aufnahme der Spindel dient. Es sind zwar schon derartige Hilfsvorrichtungen bekannt geworden, die entweder um eine senkrechte Achse drehbar waren oder bei welchen das Werkzeug in der Horizontalachse drehbar war, oder wo schließlich das Werkzeug in senkrechter Richtung verstellbar war, jedoch haben alle diese bekannten Vorrichtungen nur eine beschränkte Verwendbarkeit, entsprechend der einseitigen Verstellbarkeit. Demgegenüber besitzt der Gegenstand der vorliegenden Erfindung den großen Vorteil, daß die Hilfsvorrichtung zur Ausführung von allen auf der Drehbank möglichen Schneidarbeiten benutzt werden kann, gleichgültig ' ob die Arbeit im Innern oder an der Außenseite des Arbeitsstückes ausgeführt wird oder ob kurvenförmige oder gerade Arbeiten gemacht werden sollen. In allen Fällen kann die Hilfsvorrichtung die Arbeit mit großer Genauigkeit ausführen, wobei die jeweilige Verstellung stets meßbar ist. Die nach dieser Erfindung konstruierte Vorrichtung wird auf der Werkzeugplatte des Supports angeordnet und ist auf bei liegender Zeichnung zur Veranschaulichung gekommen, und zwar istίο carries, in which again one also around the horizontal axis rotatable sleeve is located, which serves to accommodate the spindle. There are already such auxiliary devices became known, which were either rotatable about a vertical axis or in which the tool in the Horizontal axis was rotatable, or where finally the tool in the vertical direction was adjustable, but all these known devices have only a limited one Usability, according to the one-sided adjustability. In contrast, the The present invention has the great advantage that the auxiliary device for All cutting work possible on the lathe can be used, regardless of whether the work is inside or is carried out on the outside of the workpiece or whether curved or work is about to be done. In all cases, the auxiliary device can Carry out work with great accuracy, the respective adjustment always being measurable is. The apparatus constructed in accordance with this invention is mounted on the die plate of the support and is on the accompanying drawing for illustration come, and that is

Wie aus den Zeichnungen ersichtlich, besteht diese Hilfsvorrichtnng aus einem Pfeiler ι, an welchem die ganze Vorrichtung verstellbar angeordnet ist. Dieser Pfeiler ist auf der Werkzeugplatte 2 des Supports angeordnet und auf derselben verstellbar befestigt, d. h. er ist um den Bolzen 3, der durch den Pfeiler hindurchgeht und in einer Führungshülse 4 befestigt werden kann, drehbar, wobei der Bolzenkopf in einem Schlitz der Werkzeugplatte festgehalten wird. Auf diesem Pfeiler gleitet mittels Feder und Nut 8 ein Bügel 9, wobei die Bewegung dieses Bügels auf dem Pfeiler durch eine Schraubenspindel 10, die parallel mit dem Pfeiler geht, bewirkt wird. Diese Spindel arbeitet in einemAs can be seen from the drawings, this auxiliary device consists of a pillar ι, on which the entire device is adjustable. This pillar is arranged on the tool plate 2 of the support and adjustably fastened on the same, d. H. it can be rotated around the bolt 3, which passes through the pillar and can be fastened in a guide sleeve 4, wherein the bolt head is held in a slot in the tool plate. A tongue and groove 8 slides on this pillar a bracket 9, the movement of this bracket on the pillar by a screw spindle 10, which goes parallel with the pillar, is effected. This spindle works in one

Claims

Approach 11 of the bracket 9 and is rotated by the handle 12. A scale 13 on the column coincides with the screw thread of the spindle IO and can be read from the sharpened edge 14 on the bracket 9. The periphery of the collar .15 on the spindle 10 is also graduated in order to be brought into alignment with the notch 16 when the spindle is turned a quarter turn. The bracket 9 can be _{adjusted to Y 64} inches against the pillar if the scale 13 is set in 16 parts to 1 inch. It goes without saying, however, that this division can be selected more or less finely. The bracket 9 is attached to the pillar by bolts 17. In the extension 18 of the bracket 9, a slot 19 is cut, which forms a bearing for the conical head 20 on the extension 21 of the bracket or spindle holder 22 (Fig. 3, 4, 6 and 8). This bearing is completed by a wedge 23 and by the bolt 24 (Fig. 5). The attachment 21 can be removed from the attachment 18 by loosening the bolt 24 and the wedge 23. The edge of one of these lugs is graduated and can be brought into line with a notch in the other lug, corresponding to the angle of the axis of the spindle holder with respect to the axis of the pillar. A bearing sleeve 25 is arranged in the axial direction of the spindle holder 22; the spindle holder 22 is tightened by bolts 26 (Fig. 6) to secure the bearing sleeve 25 so that this sleeve can be pulled out and rotated. In ball bearings of this sleeve 25, the spindle 27 is rotatable, the ends of which are provided with screw threads (FIG. 7). At one end this spindle is provided with a hand crank or a cord pulley 28, by means of which the spindle is set in rotation. The chuck or the like for receiving the workpiece is arranged on the other end of the spindle.

Is the work piece (metal or wood) clamped on the lathe and the tool attached to one end of the spindle 27 and the disk 28 is now driven by cord or belt, so the construction of this device allows work to be carried out on any one Points or at any angle or inclination, d. H. In addition to the movements of the support, the pillar can stand on it rotate while the bracket 9 can slide in the vertical direction on the pillar and the spindle holder 22, which carries the spindle 27, is rotatable in the bracket 9. Will the device is used as a workpiece holder, so the work item can be in any Can be held so that it can be drilled, knurled, cut or otherwise in any way machined in one direction by the tool carried by the lathe can be.

If the object to be processed is held by the spindle 27, the cord disc 28 can be removed and replaced with a graduated, notched wheel 29. A resilient adjustment pin 30, which is carried by the bracket 31, comes here with the Notches of the wheel 29 engaged so that the work continued step by step can be. The bracket 31 · has a prismatic foot 32, which is in the Spindle holder 22 is mounted and is secured here by a washer 33. This disc is cut off at 34 to allow the bracket 31 to be removed. These Device can be used for cutting teeth of a gear, the unfinished wheel is held by spindle 27 while the knife is on the lathe is arranged.
