Abstract

In a workpiece (5), the bore (6) can be cylindrically ground internally and at the same time a rear flat face (8, 9) running at right angles to the bore (6) can be face-ground by the mushroom-shaped design of the abrasive wheel (2). This is advantageously also carried out in an oscillating manner with a tapering base part (3) of the abrasive wheel (2) while inclining the axis of rotation of the grinding arbor. <IMAGE>

Description

Die Erfindung betrifft einen Schleifkörper für eine Schleifmaschine zum gleichzeitigen Innen-, und/oder Planschleifen von Werkstücken.The invention relates to a grinding body for a grinding machine for simultaneous internal and / or surface grinding of workpieces.

In der EP-OS 00 51 136 wird eine Schleifmaschine beschrieben, mit welcher gleichzeitig mehrere Schleifvorgänge durchgeführt werden können. Für jeden Schleifvorgang ist aber ein entsprechender Schleifkörper mit zugehöriger Schleifeinheit notwendig. Je mehr unterschiedliche Schleifvorgänge an einem Werkstück durchgeführt werden sollen, um so mehr Schleifeinheiten müssen bei einer solchen Schleifmaschine vorgesehen werden.EP-OS 00 51 136 describes a grinding machine with which several grinding processes can be carried out simultaneously. For each grinding process, however, a corresponding grinding tool with the associated grinding unit is necessary. The more different grinding processes to be carried out on a workpiece, the more grinding units must be provided in such a grinding machine.

Der Erfindung liegt die Aufgabe zugrunde, die Anzahl der notwendigen Schleifeinheiten beim simultanen Schleifen von Bohrungen und rück- bzw. vorderseitigen Planschleifen eines Werkstückes zu reduzieren.The invention has for its object to reduce the number of grinding units required for simultaneous grinding of bores and back or front face grinding of a workpiece.

Zur Lösung dieser Aufgabe werden die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmale vorgeschlagen.To solve this problem, the features specified in the characterizing part of claim 1 are proposed.

Bei entsprechender Steuerung der Schleifeinheit mit einem solchen Schleifkörper kann in einem einzigen Steuerungsvorgang sowohl Innenrund- als auch plangeschliffen werden.With appropriate control of the grinding unit with such a grinding body, both internal cylindrical and face grinding can be ground in a single control process.

In der Zeichung sind Ausführungsbeispiele dargestellt. Es zeigen:

  • Fig. 1 den Bereich des zu schleifenden Werkstückes mit dem Schleifkörper in Schleifstellung.
  • Fig. 2 eine andere Schleifkörperanordnung.
Exemplary embodiments are shown in the drawing. Show it:
  • Fig. 1 shows the area of the workpiece to be ground with the grinding body in the grinding position.
  • Fig. 2 shows another grinding wheel arrangement.

Auf dem Schleifdorn 1 ist der pilzförmige Schleifkörper 2 mit seinem Fußteil 3 und seinem Kopfteil 4 befestigt. Mit 5 ist ein Werkstück bezeichnet, dessen Bohrung 6 innenrund geschliffen werden soll und außerdem zu schleifende Planflächen 7, 8 und 9 aufweist. Die Planflächen 7 bzw. 9 werden über die angedeuteten separaten Schleifscheibe 10 geschliffen, wobei die Schleifscheibe 10 auch die Stellung 11 einnimmt. Mit dem pilzförmigen Schleifkörper 2 kann gleichzeitig die Bohrung 6 und die Planfläche 8 geschliffen werden. Während das Werkstück 5 um die Achse 12 rotiert ist die Drehachse 13 des Schleifdorns 1 hierzu etwas schräg gestellt. Gleichzeitig ist das Fußteil kegelförmig verjüngt ausgebildet. Schrägstellung der Drehachse 13 zur Achse 12 und kegelförmige verjüngung des Fußteiles 3 sind so aufeinander abgestimmt, daß die Bohrung 6 innenrund geschliffen werden kann, aber gleichzeitig die Planfläche des Kopfteiles 4 die Planfläche 8 des Werkstückes schleifen kann. Weil die hintere Planfläche des Kopfteiles 4 rechtwinklig zur Schleiffläche des Fußteiles 3 angeorndet ist, erfolgt durch die Schrägstellung des Schleifdornes 1 der Schliff nur an den in der Zeichnung angedeuteten Berühungsstellen.The mushroom-shaped grinding body 2 is fastened to the grinding arbor 1 with its foot part 3 and its head part 4. 5 denotes a workpiece, the bore 6 of which is to be ground on the inside and also has flat surfaces 7, 8 and 9 to be ground. The flat surfaces 7 and 9 are ground over the indicated separate grinding wheel 10, the grinding wheel 10 also occupying position 11. The bore 6 and the flat surface 8 can be ground simultaneously with the mushroom-shaped grinding body 2. While the workpiece 5 rotates about the axis 12, the axis of rotation 13 of the grinding mandrel 1 is slightly inclined. At the same time, the foot part is conically tapered. Inclination of the axis of rotation 13 to the axis 12 and conical taper of the foot part 3 are coordinated so that the bore 6 can be ground internally, but at the same time the flat surface of the head part 4 can grind the flat surface 8 of the workpiece. Because the rear flat surface of the head part 4 is arranged at right angles to the grinding surface of the foot part 3, the inclination of the grinding mandrel 1 results in the grinding only at the contact points indicated in the drawing.

Fig. 2 zeigt eine andere Anordnung des Schleifkörpers, so daß neben der Bohrung 6 von dem Schleifkörper 2 gleichzeitig die dem Schleifdorn 1 zugewandte Planfläche 9 geschliffen werden kann. In diesem Falle ist der Fußteil 3 zum Kopftteil 4 hin kegelförmig erweitert. Für die Schleifgenauigkeit ist der auf diese Weise für das Planschleifen mögliche stabile und kurze Schleifdorn von großem Vorteil.Fig. 2 shows another arrangement of the grinding body, so that in addition to the bore 6 of the grinding body 2, the flat surface 9 facing the grinding mandrel 1 can be ground at the same time. In this case, the foot part 3 is widened conically towards the head part 4. For the grinding accuracy the is on In this way, possible stable and short grinding arbors are of great advantage for face grinding.

Das gleichzeitige Einstechschleifen einer Bohrung mit dazugehöriger rückseitiger Planfläche ist durch den pilzförmigen Schleifkörper mit kegelförmigem Fußteil und gleichzeitiger Schrägstellung des Schleifdornes auch oszillierend möglich.The simultaneous plunge grinding of a hole with the corresponding flat face on the back is also possible with an oscillating motion thanks to the mushroom-shaped grinding body with a conical base and simultaneous inclination of the grinding mandrel.
