Description

Schleifmaschine für Schälmesser.Grinder for peeling knives.

Die Erfindung bezieht sich auf eine Schleifmaschine nach dem Oberbegriff von Anspruch 1. Schleifmaschinen zum Schleifen (Abziehen) von Drehwerkzeugen sind weit verbreitet.The invention relates to a grinding machine according to the preamble of claim 1. Grinding machines for grinding (removing) turning tools are widely used.

Bei der Innenbearbeitung von Bohrungen können je nach Anordnung des Messers in der Bohrung, insbesondere bei Schrägstellung der Messer, nicht geradlinige Schneidkanten an den Messern erforderlich werden, deren Kontur von Hand schlecht oder nicht angeschliffen werden kann.When drilling holes internally, depending on the arrangement of the knife in the hole, especially when the knife is at an angle, non-rectilinear cutting edges may be required on the knives, the contour of which cannot be sharpened by hand or not.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Schleifvorrichtung zu entwickeln, die den besonderen Anforderungen an eine Schneidkantenform für schräggestellte Schneidmesser zur Bearbeitung von zylindrischen Bohrungen entspricht.The invention is therefore based on the object of developing a grinding device which meets the special requirements for a cutting edge shape for inclined cutting knives for machining cylindrical bores.

Die Lösung dieser Aufgabe ist im kennzeichnenden Teil von Anspruch 1 beschrieben. Die Topfform der Schleifscheibe berücksichtigt die beanspruchte Verschiebbarkeit der Spannmittel, wobei das bearbeitete Schneidmesser wie später bei der Bearbeitung der Bohrung axial zur Drehachse der Schleifmaschinenspindel an der zylindrischen Innenwand der Schleifscheibe vorbeigeführt wird und dabei der Bohrungsinnenfläche entsprechend geschliffen wird. Da nicht für jeden Bohrungsdurchmesser ein entsprechender Schleifscheibeninnendurchmesser zur Verfügung steht, wird die Anpassung an den gewünschten Bohrungsdurchmesser durch eine geänderte Neigung des Trägersegments zur Spindelachse erreicht.The solution to this problem is described in the characterizing part of claim 1. The cup shape of the grinding wheel takes into account the stressed displaceability of the clamping device, whereby the machined cutting knife is guided past the cylindrical inner wall of the grinding wheel axially to the axis of rotation of the grinding machine spindle, as is the case later when machining the bore, and the inner surface of the bore is ground accordingly. Since not a ent for every bore diameter Voice S is chleifscheibeninnendurchmesser available, to adapt to the desired bore diameter by a changed inclination of the support segment is reached to the spindle axis.

Durch die Schrägstellung der Schnittflächen der Schneidmesser - insbesondere der Nebenschneiden - relativ zur Längsachse der Bohrung, erhalten die Schneidkanten eine konvexe Form. Zusätzlich zu dieser Neigung des zu schleifenden Schneidmessers müssen für jeden Durchmesser der zu fertigenden Bohrung die Spannmittel um ihre zur Spindeldrehachse der Schleifscheibe parallele Achse geschwenkt werden, um somit dem Schneidmesser den richtigen Freiflächenwinkel vermitteln zu können. Mit einer Schwenkung des Trägersegments um die zur Spindeldrehachse der Schleifscheibe parallele Schwenkachse der Spannmittel wird der Freiflächenwinkel bestimmt. Die Ausgestaltung der erfindungsgemäßen Schleifmaschine mit dieser weiteren Drehachse für die Spannmittel, zusätzlich zu der Verschwenkbarkeit der Trägersegmente um die Achse quer zur Drehachse der Schleifscheibenspindel ist eine Besonderheit für Schneidmesser deren Freiflächenwinkel variiert werden müssen. Weiterhin ist zur richtigen Wahl der Neigung der Schneiden um die die Schleifscheibenspindelachse-querende Schwenkachse wichtig, daß der Mittelpunkt des Kreissegments mit der Längsmitte der zu bearbeitenden Schneide zusammenfällt, da sich die Schneidenkrümmung auch nach dem Schwenkpunkt des Trägersegments bestimmt.Due to the inclined position of the cutting surfaces of the cutting knives - in particular the secondary cutting edges - relative to the longitudinal axis of the bore, the cutting edges are given a convex shape. In addition to this inclination of the cutting knife to be ground, the clamping means for each diameter of the bore to be manufactured must be pivoted about their axis parallel to the axis of rotation of the grinding wheel, in order to be able to impart the correct flank angle to the cutting knife. The flank angle is determined by pivoting the carrier segment about the pivot axis of the clamping means parallel to the spindle rotation axis of the grinding wheel. The design of the grinding machine according to the invention with this further axis of rotation for the clamping means, in addition to the pivotability of the carrier segments about the axis transverse to the axis of rotation of the grinding wheel spindle, is a special feature for cutting knives whose flank angle must be varied. Furthermore, for the correct choice of the inclination of the cutting edges around the swiveling axis crossing the grinding wheel spindle axis, it is important that the center point of the circular segment coincides with the longitudinal center of the cutting edge to be machined, since the cutting edge curvature is also determined by the pivot point of the carrier segment.

Um eine wirklichkeitsgetreue Übertragung der Schneidenverhältnisse aus der Bohrung auf die Schleifscheibe zu erzielen, ist die Ebene des Kreises, in der das in den Trägersegment eingespannte Schneidmesser geschwenkt wird, parallel oder annähernd parallel zu der Tangentialebene am Umfang der Schleifscheibe in der das Schneidmesser also hier das Werkstück, die Schleifscheibe berührt.In order to achieve a realistic transfer of the cutting conditions from the hole to the grinding wheel, the plane of the circle in which the cutting knife clamped in the carrier segment is pivoted is parallel or almost parallel to the tangential plane on the circumference of the grinding wheel in which the cutting knife is here Workpiece touching the grinding wheel.

Bei der vorzugsweise entsprechend Anspruch 2 ausgestalteten Schleifmaschine kann unter Berücksichtigung der Schrägstellung der Messer dem Umstand Rechnung getragen werden, daß unterschiedliche Längsabschnitte der SChneidkanten eines Schneidmessers bearbeitet werden müssen. Durch eine entsprechende Wahl der Lageanordnung der Aufnahme für die Schneidmesser in den Trägersegmenten kann somit den übrigen Forderungen nach richtiger Lage der zu bearbeitenden Schneide Rechnung getragen werden.In the grinding machine, which is preferably designed in accordance with claim 2, the fact that different longitudinal sections of the cutting edges of a cutting knife have to be machined can be taken into account, taking into account the inclined position of the knives. By appropriately selecting the position of the receptacle for the cutting knives in the carrier segments, the remaining requirements for the correct position of the cutting edge to be machined can thus be met.

Zur Vereinfachung der Einstellung des Freiflächenwinkels an den Schneiden der Schneidmesser kann die Ausgestaltung der Erfindung gem. Anspruch 3 vorgesehen sein. Dadurch ist gewährleistet, daß ohne Veränderung der anderen Parameter der Freiflächenwinkel variiert werden kann.To simplify the setting of the flank angle on the cutting edges of the cutting knives, the embodiment of the invention can. Claim 3 can be provided. This ensures that the flank angle can be varied without changing the other parameters.

  • F ig. 4 shows a detail from FIG. 3.

Die Schleifmaschine 1 besteht aus einem Tisch 7, darauf angeordneten Spannmitteln 8 für ein Schneidmesser 2, aus einer napfförmigen, hohlzylindrischen Schleifscheibe 6, die stirnseitig a n einer Spindel 5 befestigt ist. Die Schleifscheibe rotiert um die Drehachse 9 der Spindel 5 in Richtung des Pfeiles 20. Auf dem Spanntisch 7 ist parallel zur Drehachse 9 der Smindel 5 eine Schiene 21 angeordnet. Entlang dieser werden entsprechend Pfeil 10 die Spannmittel 8 hin- und hergeschoben. Diese Bewegung kann von Hand oder von einem nicht dargestellten Motor durchgeführt werden. Der Schlitten 16 gleitet unmittelbar an der Schiene 21 entlang. Er hat eine Bohrung, in die ein Bolzen 18 eines Spannkopfes 17 eingreift. Der Spannkopf 17 ist entsprechend Pfeil 22 mit dem Bolzen 18 in der Bohrung des Schlittens 16 dreheinstellbar und durch die seitlich geschlitzte Ausführung des Schlittens und die Spannschraube 23 in der gewählten Winkellage arretierbar. Der Spannkopf 17 hat an seinem schleifscheibenseitigen Ende eine kreissegmentförmige Führung 12, in der ein Trägersegment 15 entsprechend Pfeil 31 winkelverstellbar angeschraubt ist. Der Mittelpunkt 13 der Schwenkbewegunq des Trägersegments 15 fällt mit der Längsmitte der bearbeiteten Schneide zusammen. (Vergl. Fig. '2)The grinding machine 1 consists of a table 7, clamping means 8 arranged thereon for a cutting knife 2, and a cup-shaped, hollow-cylindrical grinding wheel 6 which is attached to a spindle 5 on the end face. The grinding wheel rotates about the axis of rotation 9 of the spindle 5 in the direction of the arrow 20. A rail 21 is arranged on the clamping table 7 parallel to the axis of rotation 9 of the spindle 5. The clamping means 8 are pushed back and forth along this in accordance with arrow 10. This movement can be carried out by hand or by a motor, not shown. The carriage 16 slides directly along the rail 21. It has a bore into which a bolt 18 of a clamping head 17 engages. The clamping head 17 can be rotated according to arrow 22 with the bolt 18 in the bore of the carriage 16 and can be locked in the selected angular position by the laterally slotted design of the carriage and the clamping screw 23. The clamping head 17 has at its end on the grinding wheel side a circular segment-shaped guide 12 in which a carrier web element 15 is screwed in an angle-adjustable manner according to arrow 31. The center point 13 of the pivoting movement of the carrier segment 15 coincides with the longitudinal center of the machined cutting edge. (See Fig. '2)

Die Drehachse 9 der Spindel 5 verläuft narallel zur Drehachse 11 des Bolzens 18. Die Drehachse 11 geht durch den Mittelpunkt des Kreises der segmentförmigen Führung 12. Dieser Mittelnunkt und die Längsmitte der zu bearbeitenden Nebenschneide 3 fallen zusammen. Die Drehachse 11 berührt den inneren Umfang der Schleifscheibe 6.
Zur Bearbeitung einer anderen Schneide, z.B. der Hauptschneide 4 des Schneidmessers 2, wird ein anderes Trägersegment 19 eingesetzt, das eine entsprechende Aufnahme für die jeweilige Lage des Schneidmessers aufweist.The axis of rotation 9 of the spindle 5 runs parallel to the axis of rotation 11 of the bolt 18. The axis of rotation 11 passes through the center of the circle of the segment-shaped guide 12. This center point and the longitudinal center of the secondary cutting edge 3 to be machined coincide. The axis of rotation 11 touches the inner circumference of the grinding wheel 6.
In order to machine another cutting edge, for example the main cutting edge 4 of the cutting knife 2, another carrier segment 19 is used, which has a corresponding receptacle for the respective position of the cutting knife.

Die Schleifmaschine wird so eingestellt, daß die Situation des Schneidmessers in der Bohrung nachempfunden wird. Zunächst wird die Neigung der Schneidkante bzw. der Schnittfläche 30 des Messers 2 relativ zur Bohrungslängsachse, bzw. entsprechend relativ zur Spindelachse 9 eingestellt ( vergl. Fig. 2). Diese Einstellung erfolgt mit Hilfe der Skala 24 am Spannkopf 17 und des Zeigers 25 am Trägersegment 15. Im Anschluß daran wird die Dreheinstellung des Spannkopfes 17 an Hand der Skala 26 und des Zeigers 27 vorgenommen. Hier wird der Freiflächenwinkel der zu bearbeitenden Schneide festgelegt.The grinding machine is set so that the situation of the cutting knife in the bore is modeled. First, the inclination of the cutting edge or the cutting surface 30 of the knife 2 is set relative to the longitudinal axis of the bore, or correspondingly relative to the spindle axis 9 (see FIG. 2). This setting is made with the aid of the scale 24 on the clamping head 17 and the pointer 25 on the carrier segment 15. The rotary setting of the clamping head 17 is then carried out using the scale 26 and the pointer 27. The free surface angle of the cutting edge to be machined is specified here.

Das Trägersegment 15 wird in der gewünschten Stellung durch die Schrauben 28, 29 arretiert, der Bolzen 18 und damit der Spannkopf 17 wird durch die Spannschraube 23 festgelegt. Die Gesamtheit aus Schlitten 16, Spannkopf 17, Trägersegment 15 und Schneidmesser 2 wird nach erfolgter Einstellung der Schleifmaschine entlang der Schiene 21 hin- und hergeschoben, bis daß die Schleifscheibe 6 keinen Abtrag am Schneidmesser mehr vornimmt.The T support segment 15 is locked in the desired position by the screws 28, 29, the bolt 18 and thus the clamping head 17 is fixed by the clamping screw 23. The whole of the carriage 16, clamping head 17, carrier segment 15 and cutting knife 2 is pushed back and forth along the rail 21 after the grinding machine has been adjusted until the grinding wheel 6 no longer removes the cutting knife.

Mit der erfindungsgemäßen Schleifmaschine ist jede beliebige Gestaltung der Schneidkanten und der angrenzenden Winkel des Schneidmessers, soweit sie zur Innenbearbeitung von Bohrungen benötigt wird, möglich.With the grinding machine according to the invention, any design of the cutting edges and the adjacent angles of the cutting knife, insofar as it is required for the internal machining of bores, is possible.
