Description

Vorrichtung zum Halten der Messer in der Messerwelle für Hobelmaschinen Die Erfindung betrifft eine Vorrichtung zum Halten der Messer in der Messerwelle für Hobelmaschinen, und zwar die Art; bei der zwischen dem Messer und der durch Spannschrauben radial verstellbaren Keilleiste eine gegen radiale Verschiebung beim Verspamnen gesicherte Druckleiste eingeschaltet ist. Während diese Sicherung bisher durch eine ,an der Druckleiste sitzende seitliche und in eine besondere Führungsnut eingreifende Leiste erfolgt, wird gemäß der vorliegenden Erfindung die Druckleiste mit einem unterdie Keilleiste greifenden winkligen Ansatz versehen, auf dem die Spannschrauben abgestützt sind. Es Wird hierdurch die nur schwer genau passend herstellbare besondere Nut entbehrlich, während die Herstellung des winkligen Ansatzes keine 'besonderen Schwierigkeiten macht.Device for holding the knife in the knife shaft for planing machines The invention relates to a device for holding the knife in the knife shaft for planing machines, namely the type; at the between the knife and the through Clamping screws radially adjustable V-ledge a counter radial displacement when Spam the secured print bar is switched on. While this backup so far through a lateral and special guide groove on the pressure bar engaging bar takes place, according to the present invention, the pressure bar provided with an angled approach reaching under the V-ledge on which the Clamping screws are supported. This makes it difficult to manufacture to fit exactly special groove unnecessary, while the production of the angled approach no 'creates particular difficulties.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Schnitt dargestellt.The drawing shows an exemplary embodiment of the subject matter of the invention shown in section.

Der Wellenkörper i ist zweckmäßig mit vier über den Umfang gleichmäßig verteilten Nuten 2 versehen, deren Flanken 3 und derart zueinander verlaufen, daß sich die Nut 2 nach außen verjüngt. An der Flanke 4. stützt sich das Messer 5 ab, gegen das sich andererseits leine spitzwinklige Druckleiste. 6 legt, an der eine den verbleibenden Raum ausfüllende Keilleiste 7 anliegt. Letztere besitzt Bohrungen für Spannschrauben 8, durch welche die Keilleiste 7 in der sich verjüngenden Nut 2 nach außen gedrückt wird. Die Spannschrauben 8 stützen sich auf dem unter die Keilleiste 7 greifenden winkligen Ansatz 9 der Druckleiste 6 ab.The shaft body i is expediently uniform with four over the circumference provided distributed grooves 2, the flanks 3 and 3 extend to each other that the groove 2 tapers outwards. The knife 5 is supported on the flank 4, against which on the other hand there is an acute-angled pressure bar. 6 attaches to the one the remaining space filling V-ledge 7 is applied. The latter has holes for clamping screws 8, through which the V-ledge 7 in the tapered groove 2 is pushed outwards. The clamping screws 8 are based on the under the Wedge bar 7 engaging angled approach 9 of the pressure bar 6.

Durch diese Einrichtung wird beim Anziehen der Spannschrauben 8 gleichzeitig das Messer 5- festgeklemmt, der unter die Keilleiste 7 greifende winklige Ansatz 9 der Druckleiste 6 gegen .seine Auflage io gedrückt und somit ein radiales Verlagern der Druckleiste und des Messers vermieden.With this device, when tightening the clamping screws 8, at the same time the knife 5- clamped, the under the V-ledge 7 reaching angled approach 9 of the pressure bar 6 pressed against its support io and thus a radial displacement the pressure bar and the knife avoided.

Vorteilhaft ist der Schenkel 9 der Druckleiste 6 mit einer Stützfläche i i versehen, die senkrecht zur Achse der Spannschraube 8 verläuft.The leg 9 of the pressure bar 6 is advantageous with a support surface i i provided which runs perpendicular to the axis of the clamping screw 8.
