Abstract
Description
Die Erfindung betrifft eine Schleifmaschine, insbes. eine Feinschleifmaschine, für im Querschnitt zylindrische Werk stücke (z. B. ringförmige zylindrische Werkstücke), - mit rotierbarer Werkstückaufnahme, die Anlageflächen für die Werk stücke aufweist. Die Rotationsbewegung der Werkstückaufnahme kann über Treiber erfolgen, die am Werkstück angreifen, die Werkstückaufnahme kann aber auch angetrieben sein.The invention relates to a grinding machine, in particular a fine grinding machine, for workpieces which are cylindrical in cross section (for example annular cylindrical workpieces), - with a rotatable workpiece holder which has contact surfaces for the workpieces. The rotational movement of the workpiece holder can take place via drivers which engage the workpiece, but the workpiece holder can also be driven.
Bei der aus der Praxis bekannten Schleifmaschine, von der die Erfindung ausgeht, sind die Anlageflächen Ringflächen, deren Ebene orthogonal zur Rotationsachse erfolgt. Daraus resultieren Nachteile, weil an der Anlagefläche keine Zen trierung der mit der Werkstückaufnahme rotierenden Werkstücke erfolgt.In the grinding machine known from practice, from the the invention is based, the contact surfaces are ring surfaces, whose plane is orthogonal to the axis of rotation. Out of it Disadvantages result because there is no Zen on the contact surface the workpieces rotating with the workpiece holder he follows.
Der Erfindung liegt die Aufgabe zugrunde, eine Schleifmaschi ne des eingangs beschriebenen Aufbaus zu schaffen, bei der die zu bearbeitenden Werkstücke in der Werkstückaufnahme auch eine Zentrierung erfahren.The invention has for its object a grinding machine ne to create the structure described above, in which the workpieces to be machined in the workpiece holder too experience a centering.
Zur Lösung dieser Aufgabe lehrt die Erfindung, daß die Werk stückaufnahme konische Anlageflächen für die Werkstücke auf weist und daß die Werkstücke mit einer Umfangskante an der konischen Anlagefläche anliegen. Handelt es sich um Werkstük ke, die innen zu bearbeiten sind, so arbeitet man im Rahmen der Erfindung mit konischen Anlageflächen, die als Außenkonus flächen zu bearbeiten sind. Handelt es sich um Werkstücke, die außen bearbeitet werden müssen, so arbeitet man mit ko nischen Anlageflächen, die als Außenkonusflächen ausgebildet sind.To achieve this object, the invention teaches that the work piece conical contact surfaces for the workpieces points and that the workpieces with a peripheral edge on the conical contact surface. Is it a workpiece Ke, which are to be processed inside, so you work in the frame the invention with conical contact surfaces, which as an outer cone areas to be processed. If it is workpieces, that have to be processed on the outside, that's how you work with ko African contact surfaces, which are designed as outer conical surfaces are.
Die erreichten Vorteile sind darin zu sehen, daß bei der er findungsgemäßen Schleifmaschine die Werkstücke in der Werk stückaufnahme auch eine Zentrierung erfahren. Diese Zentrie rung erfolgt über den gesamten Umfang der zu bearbeitenden Werkstücke, so daß einspannungsbedingte Ungenauigkeiten nicht zu befürchten sind.The advantages achieved can be seen in the fact that he inventive grinding machine the workpieces in the factory piece recording also experience a centering. This center tion takes place over the entire scope of the work to be done Workpieces, so that clamping inaccuracies are not are to be feared.
Im folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung ausführlicher erläutert. Es zeigen in schematischer DarstellungIn the following, the invention is based on only one Embodiment representing drawing in more detail explained. They show a schematic representation
Fig. 1 einen Axialschnitt durch eine erfindungsgemäße Schleif maschine im Bereich der Werkstückaufnahme, ausschnitts weise, Fig. 1 is an axial section through an inventive grinding machine in the region of the workpiece holder, as the cutout,
Fig. 2 eine andere Ausführungsform des Gegenstandes der Fig. 1 und Fig. 2 shows another embodiment of the object of Fig. 1 and
Fig. 3 den Gegenstand der Fig. 1 mit konstruktiven Einzel heiten. Fig. 3 units the subject of Fig. 1 with constructive single.
Bei der in den Figuren ausschnittsweise dargestellten Schleif maschine mag es sich um eine Feinschleifmaschine handeln. Sie ist für die Schleifbearbeitung von im Querschnitt kreis förmigen Werkstücken 1 eingerichtet. Dabei mag es sich um ringförmige oder um zylindrische Werkstücke 1 handeln. Die Schleifmaschine besitzt eine rotierbare Werkstückaufnahme 2, die Anlageflächen 3 für die Werkstücke 1 aufweist.The grinding machine shown in sections in the figures may be a fine grinding machine. It is set up for grinding machining of circular workpieces 1 in cross section. This may be ring-shaped or cylindrical workpieces 1 . The grinding machine has a rotatable workpiece holder 2 , which has contact surfaces 3 for the workpieces 1 .
Aus einer vergleichenden Betrachtung der Fig. 1 und 2 entnimmt man, daß die Werkstückaufnahme 2 konische Auflageflächen 3 für die jeweils zu bearbeitenden Werkstücke 1 aufweist. Die Anordnung ist so getroffen, daß die Werkstücke 1 mit einer Umfangskante 4 an den konischen Anlageflächen anliegen. Die Umfangskante kann mit einer Fase versehen sein (vgl. Fig. 1).Take from a comparison of FIGS. 1 and 2 in that the workpiece holder 2 has conical contact surfaces 3 for each of workpieces to be processed 1. The arrangement is such that the workpieces 1 rest with a peripheral edge 4 on the conical contact surfaces. The peripheral edge can be provided with a chamfer (cf. FIG. 1).
Bei der Ausführungsform nach Fig. 1 ist die Anordnung so ge troffen, daß die konischen Anlageflächen 3 als Innenkonus flächen ausgebildet sind. Im Gegensatz dazu ist bei der Aus führungsform nach Fig. 2 die Anordnung so getroffen, daß die konischen Anlageflächen 3 als Außenkonusflächen ausgebildet sind.In the embodiment according to FIG. 1, the arrangement is such that the conical contact surfaces 3 are formed as inner cone surfaces. In contrast, in the embodiment from FIG. 2, the arrangement is such that the conical contact surfaces 3 are designed as outer conical surfaces.
Die Fig. 3 entspricht der Fig. 1, zeigt aber weitere konstruk tive Einzelheiten. Insbes. zeigt sie die konische Lagerung des Werkstückes. Fig. 3 corresponds to Fig. 1, but shows further constructive details. Esp. it shows the conical bearing of the workpiece.
