Description
Die Seitenflächen von flachen Teilen aua Holz oder ähnlichem weichen Material, wie ζ. B. Bürstenstiele u. dgl., werden derart bearbeitet, daß die in einer dem Maschinenschraubstock ähnlichen Spannvorrichtung zusammengepreßten Teile, die alle dieselbe Form erhalten sollen, von Hand an eine senkrecht stehende Frässpindel herangeführt werden, wobei die Formgebung durch die zur Begrenzung der Fräsarbeit dienende, miteingespannte Schablone erfolgt. Diese bisher bekannten' Spannvorrichtungen weisen jedoch den Nachteil auf, daß die zu bearbeitenden Einzelteile, nachdem die vordere Seitenfläche gefräst ist, zur Fertigstellung der rückseitigen Seitenfläche umgespannt werden müssen, wodurch außer dem großen Zeitverlust, der bei Massewaren schwer ins Gewicht fällt, auch meistens ein Verrutschen der einseitig bearbeiteten Teile eintrat, so daß keine genaue Übereinstimmung dieser Teile erhalten wurde. Dieser Übelstand machte sich besonders bei der Herstellung von feineren Bürstenhölzern unangenehm bemerkbar, da diese in ihrer äußeren Form übereinstimmen sollen.The side surfaces of flat parts made of wood or similar soft material, such as ζ. B. brush handles and the like., Are processed in such a way that the in one of the machine vise Similar clamping device pressed together parts, which should all get the same shape, by hand to a vertical standing milling spindle are brought up, the shape being limited by the The template used for the milling work is also clamped in. These previously known ' However, clamping devices have the disadvantage that the individual parts to be processed after the front side surface is milled, must be reclamped to complete the rear side surface, whereby In addition to the great loss of time, which is very important with bulk goods, also mostly a slipping of the one-sided processed Parts occurred so that an exact match of these parts was not obtained. This malady was particularly common the production of finer brush woods is uncomfortably noticeable, as this is in their external shape should match.
Ein weiterer Nachteil der bekannten Spannvorrichtungen besteht darin, daß die Preßspindel sehr weit hinter dem Angriffspunkt der Druckbacke angeordnet ist, wodurch das aus manchmal recht schmalen Teilen bestehende eingespannte Paket das Bestreben zeigte, auszubiegen, wodurch unliebsame Störungen im Arbeitsgange eintraten und sich des öfteren auch Arbeitsausschuß ergab.Another disadvantage of the known clamping devices is that the press spindle is arranged very far behind the point of application of the pressure jaw, which sometimes makes this out the clamped package consisting of quite narrow parts showed the tendency to bend, as a result of which unpleasant disturbances occurred in the work process and there was often also a work committee.
Durch den vorliegenden Erfindungsgegeüstand werden diese Nachteile in einfacher und sicherer Weise vermieden. Der der Erfindung zugrunde liegende Gedanke besteht darin, daß die beiden das zu bearbeitende, aus den einzelnen Teilen bestehende Paket zusammenspannenden Preßbacken zwischen den Schenkeln der U-förmig gestalteten Haltevorrichtung drehbar angeordnet sind, wobei die Einrichtung getroffen ist, daß nach Lösung der auf die Druckbacke zentrisch wirkenden Preßspindel infolge der unter Federdruck stehenden, die leichte Drehbewegung der Preßbacken bewirkenden Kugellagerringe die einzelnen Teile, da ständig unter Druck stehend, sich nicht verschieben können. Die Drehbewegung der Preßbacken um i8o° nach der einen oder anderen Richtung wird durch seitlich angeordnete Federklinken automatisch begrenzt, so daß nach Fertigstellung der Fräsarbeit der einen Seite ohne Zeitverlust die Rückseite bearbeitet werden kann. Die Feststellung der Preßbacken in der Arbeitsstellung erfolgt durch einen in eine der Preßbacken eingreifenden federnden Stellstift. Die obere Preßbacke ist schlittenartig geführt und wird durch die zentrisch zu ihr angeordnete Preßspindel verstellt.Through the present subject matter of the invention these disadvantages are avoided in a simple and safe manner. That of the invention The underlying idea is that the two of them make the work to be done the individual parts of the existing package clamping clamping jaws between the Legs of the U-shaped holding device are rotatably arranged, the Device is made that after the release of the press spindle acting centrally on the pressure jaw as a result of the ball bearing rings under spring pressure causing the slight rotary movement of the press jaws, the individual Parts cannot move because they are constantly under pressure. The rotary motion the jaws turned through 180 ° in one direction or the other through to the side arranged spring pawls automatically limited, so that after completion of the milling work of one side without loss of time the back can be edited. The determination of the press jaws in the working position takes place by a resilient adjusting pin engaging in one of the press jaws. the upper jaw is guided like a slide and is arranged centrically to it by the Adjusted press spindle.
Ein weiterer Vorteil der Spannvorrichtung besteht noch darin, daß die Schablone undAnother advantage of the jig is that the template and
die Gegenhalterplatte infolge der drehbaren Anordnung der Preßbacken stets an diesen befestigt bleiben können, wodurch das Einrichten und Festspannen der einzelnen Teile sehr erleichtert wird. Die ganze Vorrichtung wird auf dem Frästisch von Hand verschoben und an den senkrecht stehenden Frässpindeln entlanggeführt.the counter-holder plate due to the rotatable arrangement of the jaws always on these Can remain attached, thereby setting up and tightening the individual parts is very relieved. The entire device is moved by hand on the router table and guided along the vertical milling spindles.

In der U-förmig gestalteten Haltevorrichtung ι ist die untere Preßbacke 2 um den Zapfen 3 drehbar gelagert, wobei durch den unter dem Druck der Federn 4 stehenden Kugellagerring 5, der zwischen Preßbacke 2 und Druckring 6 angeordnet ist, nicht nur eine leichte Drehbeweglichkeit der Preßbacke gewährleistet ist, sondern auf diese auch während der Drehung nach Lösung des Preßspindeldruckes ständig der Druck der Federn 4 wirkt. Ober der unteren Preßbacke 2 ist die obere Preßbacke 7 in der gleichen Weise drehbar um den Zapfen 8 angeordnet, der in dem in der Haltevorrichtung 1 verschiebbaren Schlitten 9 befestigt ist, wobei auch hier zwischen der Preßbacke 7 und dem unter den Druck der Federn 10 stehenden Druckring 11 der Kugellagerring 12 angeordnet ist. Der die Preßbacke 7 tragende Schlitten 9 wird mittels der in der Haltevorrichtung gelagerten Preßspindel 13 durch Drehen des Schlüssels 14 auf bzw. nieder bewegt.In the U-shaped holding device ι the lower jaw 2 is around the Pin 3 rotatably mounted, whereby standing under the pressure of the springs 4 by the Ball bearing ring 5, which is arranged between the press jaw 2 and pressure ring 6, not only a slight rotational mobility of the press jaw is guaranteed, but also during this the rotation after releasing the press spindle pressure is constantly the pressure of the springs 4. Above the lower jaw 2 is the upper jaw 7 rotatably arranged in the same way around the pin 8, which in is attached to the slide 9 displaceable in the holding device 1, and also here between the press jaw 7 and the pressure ring under the pressure of the springs 10 11 the ball bearing ring 12 is arranged. The carriage 9 carrying the press jaw 7 is mounted in the holding device by means of the Press spindle 13 is moved up or down by turning the key 14.
Zur Begrenzung der Drehbewegung der Preßbacken 2 und damit auch der Preßbacke 7 um 18o° dienen die zu beiden Seiten der Haltevorrichtung 1 angeordneten Federklinken 15, die um die Zapfen 16 drehbar angeordnet sind und in der nach oben gehenden Begrenzungslage durch Federn 17 gehalten werden. Die Schablone 18 und die Gegenhalterplatte 19, die auswechselbar sind, werden durch Schrauben an den Preßbacken 2 bzw. 7 befestigt. "Zwischen diesen werden nun die zu bearbeitenden Teile 20 gelegt und ausgerichtet, und durch Drehen der Preßspindel 13 werden sie zusammengespannt. Die ganzeTo limit the rotational movement of the press jaws 2 and thus also the press jaw 7 at 180 ° they serve on both sides of the Holding device 1 arranged spring pawls 15, which are arranged rotatably about the pin 16 are and held in the upward limiting position by springs 17 will. The template 18 and the counter holder plate 19, which are interchangeable, are fastened by screws to the press jaws 2 and 7, respectively. "Between these will be now the parts to be machined 20 are placed and aligned, and by rotating the press spindle 13 they are clamped together. The whole
Haltevorrichtung 1 wird nunmehr von dem Arbeiter mittels der an ihr angeordneten Haltegriffe 2, wobei die Hände gegen Verletzungen durch die Frässpindel durch Schutzhauben 22 geschützt werden, gegen die senk- 60 recht stehende, sich drehende Frässpindel geführt, wobei die Begrenzung der Arbeitsfläche durch die Schablone 18 erfolgt. Ist die Vorderseite fertig bearbeitet, wird die Preßspindel 13 etwas gelöst, eine der Federklinken 65 15 heruntergedrückt und das zwischen den Preßbacken 2 und 7 eingespannte Paket um i8o° gedreht, wobei durch die inzwischen wieder hochgeschnellte Federklinke 15 automatisch die Begrenzung der Drehbewegung 70 erfolgt. Die Sicherstellung in dieser Lage erfolgt durch Einschnappen eines federnd angeordneten Stellstiftes 23, der in ein Loch der Preßbacke 7 einspringt und der vor Vornahme der Drehbewegung auch hochgehoben 75 werden muß.Holding device 1 is now arranged by the worker by means of the Handles 2, with the hands against injuries from the milling spindle by protective hoods 22 are protected against the vertically 60 rotating milling spindle, the working surface is delimited by the template 18. Is the The front side is finished, the press spindle 13 is loosened somewhat, one of the spring pawls 65 15 pressed down and the package clamped between the jaws 2 and 7 around rotated i8o °, with the spring pawl 15, which has now jumped up again, automatically the limitation of the rotary movement 70 takes place. The assurance in this situation takes place by snapping a resiliently arranged adjusting pin 23, which is in a hole of the The press jaw 7 springs in and the 75 is also lifted up before the rotary movement is carried out must become.
