Abstract

A centrifugally operated clamping device for clamping a reversible blade insert in a planing tool ensures positive engagement between the clamp and the blade. The clamping device includes a clamping wedge which has an inverted T-shaped cross-section and is positioned in a similarly configured groove in the tool. The wedge is biased relative to the bottom of the groove so that the clamp will be easily disconnected from the blade.

Description

Die Erfindung bezieht sich auf eine Schnellspannvorrichtung mit Fliehkraftbetätigung zum Festspannen eines Einweg-Wendemessers an dem Messerkopf oder der Messerwelle einer Hobelmaschine gemäß Oberbegriff des Anspruchs 1.The invention relates to a quick-action clamping device with centrifugal force actuation for clamping a disposable reversible knife to the cutter head or the cutter shaft of a planing machine according to the preamble of claim 1.

Eine Schnellspannvorrichtung dieser Art ist aus dem Dokument FR-A-2 180 088 bekannt. Der Fliehkraft-Spannkeil dieser Vorrichtung hat insgesamt einen keilförmigen Querschnitt.A quick release device of this type is known from document FR-A-2 180 088. The centrifugal clamping wedge of this device has an overall wedge-shaped cross section.

Aus dem Dokument DE-A-36 42 137 ist eine Schnellspannvorrichtung mit einem Fliehkraft-Spannkeil bekannt, der einen vorspringend verbreiterten Fuß aufweist. Eine Schraube zum Festspannen des Messers wirkt auf den Fußvorsprung. Durch die Fliehkraft wird die Einklemmung des Messers verstärkt, zugleich aber eine radial nach innen gerichtete Kraft auf den Fußvorsprung ausgeübt.From document DE-A-36 42 137 a quick release device with a centrifugal tension wedge is known, which has a protruding widened foot. A screw for clamping the knife acts on the foot projection. The centrifugal force increases the clamping of the knife, but at the same time exerts a radially inward force on the foot projection.

Aufgabe der Erfindung ist die Schaffung einer Schnellspannvorrichtung, die einen schnellen Messerwechsel mit sicherem Festspannen von Einweg-Wendemessern unter Vermeidung der Gefahr eines Unfalls und/oder einer Beschädigung von Teilen der Hobelmaschine ermöglicht.The object of the invention is to provide a quick-action clamping device which enables a quick knife change with secure clamping of disposable reversible knives while avoiding the risk of an accident and / or damage to parts of the planing machine.

Zur Lösung dieser Aufgabe ist die Schnellspannvorrichtung erfindungsgemäß durch die Kennzeichnungsmerkmale des Anspruchs 1 gekennzeichnet.To achieve this object, the quick release device according to the invention is characterized by the characterizing features of claim 1.

Die erfindungsgemäße Schnellspannvorrichtung gestattet ein sofortiges, sicheres Festspannen des Einweg-Wendemessers unmittelbar nach dem Anlassen der Hobelmaschine. Infolge der Formgebung des Fliehkraft-Spannkeils und des Nutquerschnittes im Werkzeug-Grundkörper ist ein Verschleudern des Spannkeils aus der jeweiligen Nut des Messerkopfes oder der Messerwelle ausgeschlossen, selbst bei irrtümlicher Inbetriebnahme der Hobelmaschine ohne eingesetzte Wendemesser.The quick-action clamping device according to the invention allows the disposable reversible knife to be immediately and securely clamped immediately after the planing machine has been started. Due to the shape of the centrifugal clamping wedge and the groove cross-section in the tool body, the clamping wedge cannot be thrown out of the respective groove of the cutter head or the cutter block, even if the planing machine is started up by mistake without a reversible knife being used.

Ferner wird durch die Ausgestaltung des Fliehkraft-Spannkeils ein überraschend einfacher Messerwechsel ermöglicht, wie weiter unten noch im einzelnen beschrieben wird.Furthermore, the design of the centrifugal tension wedge enables a surprisingly simple knife change, as will be described in more detail below.

Bevorzugte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen 2 bis 7 angegeben.Preferred developments of the invention are specified in the dependent claims 2 to 7.

Die Erfindung wird beispielsweise anhand zweier bevorzugter Ausführungsformen gemäss der Zeichnung näher erläutert.The invention is explained in more detail, for example, using two preferred embodiments according to the drawing.

Wie aus Fig. 1, 2 und 4 bis 6 hervorgeht, sind in den drehbaren Werkzeug-Grundkörper 1 einer Hobelmaschine axial verlaufenden Nuten 1.1 eingearbeitet. In einer jeden Nut 1.1 ist ein Fliehkraft-Spannkeil 2 angeordnet, mit dessen Hilfe jeweils eine Einweg-Wendemesser 3 festgeklemmt werden kann. Nut 1.1 und Fliehkraft-Spannkeil 2 weisen gleichermassen eine Querschnittsform auf, die im wesentlichen ähnlich wie ein auf den Kopf gestellter Buchstabe T aussieht. Der Fliehkraft-Spannkeil 2 ist über eine Anzahl elastischer Zwischenglieder, vorzugsweise von Federn 4, gegen den Nutengrund 1.2 abgestützt, wobei die Federn 4, in der Querschnittsdarstellung der Nut 1.1 gesehen (vgl. Fig. 1, 2 und 4 bis 6), in bezug auf die Mitte des Nutengrundes 1.2 unsymmetrisch angebracht sind. In einer ersten Ausführungsform der erfindungsgemässen Schnellspannvorrichtung gemäss den Fig. 1 bis 3 ist zur Gewährleistung einer genauen Führung des Fliehkraft-Spannkeils 2 bei dessen Niederdrücken in Richtung des Pfeils A zur Lösung des Einweg-Wendemessers 3 aus der Verspannung oder zum Einsetzen desselben zweckmässig jeweils zwischen Feder 4 und Nutengrund 1.2 je ein Druckkörper in der Gestalt einer Kugel 5 vorgesehen. Nach erfolgter Lösung wird das Entfernen des Einweg-Wendemessers 3 in Axialrichtung möglich (vgl. Pfeil B in Fig. 3).As can be seen from FIGS. 1, 2 and 4 to 6, axially extending grooves 1.1 are incorporated into the rotatable tool base 1 of a planing machine. A centrifugal wedge 2 is arranged in each groove 1.1, with the aid of which a disposable turning knife 3 can be clamped in place. Groove 1.1 and centrifugal clamping wedge 2 likewise have a cross-sectional shape which looks essentially similar to a letter T placed upside down. The centrifugal clamping wedge 2 is supported by a number of elastic intermediate members, preferably by springs 4, against the groove base 1.2, the springs 4, seen in the cross-sectional representation of the groove 1.1 (see FIGS. 1, 2 and 4 to 6), in are asymmetrically attached to the center of the groove base 1.2. In a first embodiment 1 to 3 is expedient to ensure precise guidance of the centrifugal force wedge 2 when it is pressed down in the direction of arrow A to release the one-way turning knife 3 from the tensioning or to insert the same between the spring 4 and the groove base 1.2 a pressure body in the form of a ball 5 is provided. After the solution has been obtained, the disposable turning knife 3 can be removed in the axial direction (see arrow B in FIG. 3).

Bei einer zweiten Ausführungsförm der Erfindung nach den Fig. 4 bis 7 weist der Fliehkraft-Spannkeil 2 besonders vorteilhaft eine Formgebung auf, so dass im festgespannten Betriebszustand desselben dessen Bodenfläche eine in bezug auf den Nutengrund 1.2 schiefe Lage einnimmt. Dabei befindet sich auf Seite des Einweg-Wendemessers 3 die axiale Unterkante des Fliehkraft-Spannkeils 2 näher am Nutengrund 1.2. Wenn der Fliehkraft-Spannkeil 2 zwecks Loslösung des Einweg-Wendemessers 3 aus der Verspannung oder zum Einsetzen desselben in Richtung des Pfeils C in Fig. 5 niedergedrückt wird, kippt er um die besagte Unterkante als eine Schwenkachse in Richtung des Pfeils D in Fig. 6, bis seine Bodenfläche am Nutengrund 1.2 satt aufliegt, und gibt gleichzeitig das Einweg-Wendemesser 3 zum Herausziehen in der Radialrichtung frei (vgl. Pfeil E in Fig. 7).In a second embodiment of the invention according to FIGS. 4 to 7, the centrifugal force wedge 2 particularly advantageously has a shape so that, in the clamped operating state thereof, its bottom surface assumes an oblique position with respect to the groove base 1.2. The axial lower edge of the centrifugal force wedge 2 is located closer to the groove base 1.2 on the side of the disposable turning knife 3. When the centrifugal tension wedge 2 is depressed in the direction of arrow C in FIG. 5 in order to release the one-way turning knife 3 from the bracing or to insert it, it tilts around the lower edge as a pivot axis in the direction of arrow D in FIG. 6 until its bottom surface rests snugly on the bottom of the groove 1.2, and at the same time releases the one-way turning knife 3 for pulling out in the radial direction (see arrow E in FIG. 7).

Die sich in Achsenrichtung des Werkzeug-Grundkörpers 1 erstreckenden Seitenflächen 2.1, 2.2 des aufragenden Mittelteils des Fliehkraft-Spannkeils 2 sowie die jeweils diesen benachbarten Geitenflächen 1.3, 1.4 der Nut 1.1 sind je um einen spitzen Steigungswinkel α, β gegen den Nutengrund 1.2 geneigt. Der Steigungswinkel α derjenigen einander benachbarten Seitenflächen 1.3 bzw. 2.1 von Nut 1.1 bzw. Fliehkraft-Spannkeil 2, zwischen denen jeweils das Einweg-Wendemesser 3 festgeklemmt wird, ist kleiner als der Steigungswinkel β der jeweiligen anderen Seitenflächen 1.4 bzw. 2.2 besagter Teile.The side surfaces 2.1, 2.2 of the upstanding central part of the centrifugal force wedge 2, which extend in the axial direction of the tool base body 1, and the respective adjacent sliding surfaces 1.3, 1.4 of the groove 1.1 are each inclined at an acute angle α, β against the groove base 1.2. The pitch angle α of those adjacent side surfaces 1.3 or 2.1 of groove 1.1 or centrifugal clamping wedge 2, between which the one-way turning knife 3 is clamped, is smaller than the pitch angle β of the respective other side surfaces 1.4 or 2.2 of said parts.

Es ist in die letztgenannte Seitenfläche 1.4 der Nut 1.1 und die damit zusammenwirkende Seitenfläche 2.2 des Fliehkraft-Spannkeils 2 je eine in Axialrichtung verlaufende Aussparung 1.5 und 2.3 eingearbeitet. Eine hierdurch über der Aussparung 2.3 entstandene Keilnase 1.7 kann beim Niederdrücken des Fliehkraft-Spannkeils 2 in die Aussparung 1.5 der Seitenfläche 1.4 der Nut 1.1 kippen und damit das Herausnehmen des Einweg-Wendemessers 3 aus der letzteren in Radialrichtung ermöglichen (vgl. Fig. 4 bis 6).In the last-mentioned side surface 1.4 of the groove 1.1 and the interacting side surface 2.2 of the centrifugal force wedge 2, a recess 1.5 and 2.3 running in the axial direction is machined in each case. A wedge nose 1.7 thus created over the recess 2.3 can tip into the recess 1.5 of the side face 1.4 of the groove 1.1 when the centrifugal clamping wedge 2 is depressed and thus enable the one-way turning knife 3 to be removed from the latter in the radial direction (cf. FIGS. 4 to 6).

Zur zentrierten Aufnahme des Einweg-Wendemessers 3 ist ferner an der zugeordneten Seitenfläche 1.3 der Nut 1.1 eine Rippe 1.6 ausgebildet, die mit einer in Axialrichtung verlaufenden Wölbung 3.1 auf der Rückseite des Einweg-Wendemessers 3 zusammenwirkt (vgl. Fig. 6).To center the disposable reversible knife 3, a rib 1.6 is also formed on the associated side face 1.3 of the groove 1.1, which cooperates with an axially extending curvature 3.1 on the back of the disposable reversible knife 3 (see FIG. 6).
