Description

Vorliegende Erfindung betrifft eine Schraubenschlitzmaschine, welche vollständig selbständig das Schlitzen und Fräsen von Schrauben ii. dgl., sowie das Auswerfen der fertigen Stücke bewirkt, wobei lediglich das Einführen der zu bearbeitenden Werkstücke von Hand vorgenommen werden muß. Die Maschine gehört zu jener Gattung, bei der die Arbeitsstücke in eine Transportscheibe eingelegt werden, welche sie durch Drehung nach der Bearbeitungsstelle befördert. Die Transportscheibe besteht zu diesem .Zweck aus zwei durch eine Feder auseinandergehaltenen Hälften, welche nur an der Bearbeitungsstelle zusammengedrückt werden, um das Werkstück festzuhalten. Die Werkstücke liegen hierbei lose in radialen V-förmigen Rinnen, welche ihrer Gestalt zufolge Werkstücke verschiedenen Durchmessers zu bearbeiten gestatten. Die beiden Scheiben klaffen an der der Bearbeitungsstelle gegenüberliegenden Seite auseinander, wodurch die fertigen Werkstücke selbsttätig ausfallen.The present invention relates to a screw slot machine which is completely self-contained the slotting and milling of screws ii. Like., As well as the ejection of the finished Pieces caused, with only the introduction of the work pieces to be processed by hand must be made. The machine belongs to the genus in which the work pieces are inserted into a transport disc, which they are rotated after the processing point promoted. For this purpose, the transport disc consists of two halves held apart by a spring. which are only pressed together at the processing point in order to hold the workpiece in place. The workpieces are here loosely in radial V-shaped grooves, which according to their shape different workpieces Allow diameter to be machined. The two disks gape at the processing point opposite side apart, whereby the finished workpieces automatically fail.

Bei den bisher bekannten derartigen Ma-In the previously known such ma-

schinen war nun der Übelstand vorhanden, daß eine Beschädigung des Schraubengewindes durch das Festklemmen der Schrauben während der Bearbeitung sehr häufig eintrat.
Dieser Ubelstahd wird nun gemäß vorliegender Erfindung dadurch vermieden, daß neben dem erwähnten Organ zum Zusammendrücken der beiden Scheibenhälften an der Bearbeitungsstelle noch ein besonderes Andrückorgan verwendet ist, welches sich während der Bearbeitung gegen die Stirnseite des Werkstücks legt, so daß es unverrückbar festgehalten ist, ohne daß der seitliche Druck sehr groß sein müßte.Machines now had the disadvantage that damage to the screw thread due to the clamping of the screws during processing occurred very often.
This Ubelstahd is now avoided according to the present invention in that, in addition to the mentioned organ for pressing the two disc halves together at the processing point, a special pressing member is used, which lies against the face of the workpiece during processing so that it is held immovably without that the pressure on the side should be very large.

Der Gegenstand vorliegender Erfindung ist auf der Zeichnung in einer beispielsweisen Ausführungsform dargestellt.The subject matter of the present invention is shown in an exemplary manner on the drawing Embodiment shown.

Fig. 3 bis 6 zeigen Einzelansichten in größerem Maßstabe. .3 to 6 show individual views on a larger scale. .

Die zu bearbeitenden Schrauben α liegen lose in einer Transportscheibe, welche vom Maschinenantrieb 3 aus in bekannter Weise mit Hilfe der Schnecke 13 und des auf der Achse 15 der Transportscheibe sitzenden Schneckenrades 14 gedreht wird, wodurch die Werkstücke α nacheinander dem Werkzeug 21 zugefülirt werden (Fig. 6). The screws α to be machined lie loosely in a transport disk, which is rotated by the machine drive 3 in a known manner with the aid of the worm 13 and the worm wheel 14 sitting on the axis 15 of the transport disk, whereby the workpieces α are fed one after the other to the tool 21 (Fig . 6).

Diese Transportscheibe besteht, nun aus den beiden Hälften 16 und 17, von denen die Scheibe 17 auf der Nabe der Scheibe 16 achsial verschiebbar ist und so viel Spiel hat, daß sie um ein Geringes kippen kann (Fig. 5). Diese beiden Scheiben 16 und 17 werden durch eine Feder 18 auseinandergedrückt und sind mit Hilfe je einer vor und hinter der Nabe der Scheibe 16 angeordneten Mutter 19 auf der Achse 15 achsial verstellbar. Zur Aufnahme der Werkstücke sind die beiden Scheiben 16 und 17 mit einer Anzahl radialer Aussparungen 20 versehen, welche V-förmig gestaltet sind.This transport disk now consists of the two halves 16 and 17, of which the Disk 17 is axially displaceable on the hub of disk 16 and has so much play, that it can tip a little (Fig. 5). These two disks 16 and 17 become pushed apart by a spring 18 and are each with the help of one in front of and behind the Hub of the disc 16 arranged nut 19 on the axis 15 axially adjustable. To the The workpieces are received by the two disks 16 and 17 with a number of radial ones Provided recesses 20 which are V-shaped.

Das Schlitzen und Fräsen der Werkstücke, beispielsweise einer Schraube a, wird mittels einer Säge, Fräse 21 o. dgl. bewirkt, welcheThe slotting and milling of the workpieces, for example a screw a, is effected by means of a saw, milling cutter 21 or the like, which

Claims

acts with respect to the axis 15 in the radial direction and sits on a rotating axis 22 in a bearing block 24, which .wird rotated continuously with the aid of its drive disks 23. During the transport of the workpieces α , the saw 21 is removed from its path, which in some known manner, for. B. by means of a cam 25, which sits on the axis 6 of the worm wheel 13. In this cam disk 25, the pin 26 of a horizontally moving rod 27 engages, which is connected to the bearing block 24, which can be moved in guides 29 of the machine frame 1 against the transport disk 16, 17 and away from it. The cam disk 25 'is designed in such a way that by means of the same the bearing block 24 is drawn towards the transport disk 16, 17 while the transport disk 16, 17 is at a standstill, while it is pushed away during its movement.

To hold the workpieces α lying loosely in the recesses 26 of the disks 16 and 17, a roller 31 is provided which presses the two disks 16 and 17 together at the processing point, whereby the workpieces α are held there. For this purpose, the roller 31 is continuously pressed against the disks 16, 17 by an adjustable spring 34.

According to the present invention, the workpieces is now for holding α a pressure member during machining, z. B. a plate 36 is provided which is under the action of a spring 37 which moves back and forth with the tool 21 and is provided with a slot for its passage (Fig. 1). During the machining of the workpieces, this' plate 36 lies against the end face and is pressed against it by its spring 37, while the tool 21 then engages even deeper during work, for which purpose the plate 36 is displaceable in the bearing block 24 by means of a guide rod 38 is stored. The slots of the finished screws b made in this way are recessed in the middle.

Due to the roller 31, the disks 16, 17 are eccentrically pressed against each other, ie only at the processing point, so that they protrude somewhat from each other at the remote points and allow the finished slotted screws b on the underside of the disk 16, 17 to fall out.
