Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Bearbeitung von Rotationsteilen umfassend mindestens einen Arbeitsschritt, in dem ein Schleifen mindestens einer Fläche des in einer Vorrichtung eingespannten Werkstücks erfolgt. Ein derartiges Verfahren ist zum Beispiel aus der Druckschrift
Die Bearbeitung von Rotationsteilen, beispielsweise Kurbelwellen oder dergleichen in der Automobilindustrie ist mit hohem Fertigungsaufwand verbunden. In der Regel werden alle relevanten Flächen eines solchen Rotationsteils mindestens einem Schleifarbeitsgang unterzogen. Andere Arbeitsgänge an dem Werkstück, wie beispielsweise das Einbringen einer stirnseitigen Bohrung erfordern bei Rotationsteilen der genannten Art, beispielsweise Kurbelwellen eine hohe Präzision. Das Einbringen einer solchen Bohrung erfolgte daher bislang in einer separaten Sondermaschine. Nach dem Stand der Technik ist somit für einen solchen Arbeitsgang eine Sondermaschine, eine eigene Arbeitsfolge und damit verbunden das erneute Einspannen des Werkstücks notwendig. Dies führt zu hohen Investitions- und Fertigungskosten.The machining of rotating parts, such as crankshafts or the like in the automotive industry is associated with high production costs. As a rule, all relevant surfaces of such a rotary part are subjected to at least one grinding operation. Other operations on the workpiece, such as the introduction of an end bore require in rotary parts of the type mentioned, for example, crankshafts high precision. The introduction of such a bore was therefore previously in a separate special machine. According to the state of the art, a special machine, a separate working sequence and, associated therewith, the re-clamping of the workpiece is thus necessary for such an operation. This leads to high investment and manufacturing costs.
Die Aufgabe der vorliegenden Erfindung besteht darin, ein Verfahren zur Bearbeitung von Rotationsteilen der vorgenannten Gattung zu vereinfachen, zur Senkung der Fertigungskosten bei Erzielung einer hohen Prozesssicherheit unter Erhalt von Werkstücken mit hohem Qualitätsstandard.The object of the present invention is to simplify a method for processing rotary parts of the aforementioned type, to reduce manufacturing costs while achieving a high process reliability to obtain workpieces of high quality standard.
Die Lösung dieser Aufgabe liefert ein erfindungsgemäßes Verfahren zur Bearbeitung von Rotationsteilen der eingangs genannten Gattung mit den Merkmalen des Hauptanspruchs. Erfindungsgemäß ist vorgesehen, dass in das für den Schleifvorgang eingespannte Werkstück in der gleichen Einspannvorrichtung mittels eines Bohrwerkzeugs mindestens eine stirnseitige Bohrung eingebracht wird. Erfindungsgemäß ist somit ein erneutes Einspannen des Werkstücks in einer dazu vorgesehenen Sondermaschine mit eigener Arbeitsfolge nicht mehr notwendig. Das Bohren, zum Beispiel das Einbringen einer stirnseitigen Passbohrung in ein Rotationsteil, beispielsweise in einen Kurbelwellenflansch erfolgt in der gleichen Einspannvorrichtung, in der auch der Schleifvorgang erfolgt. Dies kann in einer dazu geeigneten Einspannvorrichtung erfolgen. Beispielsweise kann man während eines Schleifvorgangs das Werkstück mindestens jeweils an beiden Enden in einer Einspannvorrichtung einspannen und für den Bohrvorgang die Einspannvorrichtung an mindestens einem Ende lösen und dort ein Spannfutter für ein Bohrwerkzeug anordnen, welches dann die gewünschte stirnseitige Bohrung ausführt. Vorzugsweise wird in das Werkstück stirnseitig mindestens eine Feinbohrung beziehungsweise Präzisionsbohrung eingebracht.The solution to this problem provides a method according to the invention for the machining of rotary parts of the aforementioned type with the features of the main claim. According to the invention, at least one front-side bore is introduced into the workpiece clamped for the grinding operation in the same clamping device by means of a drilling tool. According to the invention, a new clamping of the workpiece in a dedicated special machine with its own work sequence is thus no longer necessary. The drilling, for example, the introduction of a front-side fitting bore in a rotary part, for example in a crankshaft flange takes place in the same clamping device, in which also the grinding process takes place. This can be done in a suitable clamping device. For example, during a grinding operation, the workpiece can be clamped at least in each case at both ends in a clamping device and, for the drilling process, release the clamping device at at least one end and arrange there a chuck for a drilling tool, which then performs the desired frontal bore. Preferably, at least one fine bore or precision bore is introduced into the workpiece on the front side.
Gemäß einer bevorzugten Weiterbildung der Erfindung kann man vorsehen, dass nach Lösen einer Spannvorrichtung mindestens an einem Ende der Einspannung eine zusätzliche Führung des Werkstücks am Umfang geschaffen wird durch ein dazu geeignetes Führungselement, beispielsweise eine Führungslünette. Der in der Einspannvorrichtung an dem Werkzeug vorgenommene Schleifvorgang umfasst vorzugsweise mindestens ein CBN-Schleifen mittels einer Schleifscheibe.According to a preferred embodiment of the invention can provide that after loosening a clamping device at least at one end of the clamping additional guidance of the workpiece on the circumference is created by a suitable guide element, such as a guide bezel. The grinding operation performed on the tool in the chuck preferably comprises at least one CBN grinding by means of a grinding wheel.
Bislang werden Kurbelwellen in der Regel unabhängig von der Leistungsklasse mit einem hohen Fertigungsaufwand produziert. Beispielsweise werden unter anderem die Passlager nahezu aller Kurbelwellen gedreht und festgewalzt mittels einer separaten Maschine beziehungsweise Arbeitsfolge. Gemäß einer Weiterbildung der Erfindung kann diese Arbeitsfolge des Drehens und Festwalzens der Passlager entfallen und durch Schleifen der Passlager ersetzt werden. Dieses Schleifen der Passlager kann beispielsweise in der ohnehin vorgenommenen Operation des Flansch-Zapfen-Schleifens erfolgen. Auf diese Weise lassen sich die Fertigungskosten bei der Herstellung derartiger Rotationsteile, insbesondere Kurbelwellen, erheblich senken.So far, crankshafts are usually produced independently of the power class with a high production cost. For example, among other things, the ball bearing almost all crankshafts are rotated and rolled by a separate machine or sequence. According to one embodiment of the invention, this sequence of operations of turning and deep rolling the ball bearing can be omitted and replaced by grinding the ball bearing. This grinding of the pivot bearing can be done for example in the already made operation of the flange-pin grinding. In this way, the manufacturing costs in the production of such rotating parts, in particular crankshafts, can be significantly reduced.
Bei Kurbelwellen erfolgt nach dem Stand der Technik in der Regel eine Finish-Bearbeitung, unabhängig von den Anforderungen an die Kurbelwelle. Dabei werden beispielsweise Haupt-, Hublager, Flansch und Zapfen der Kurbelwelle poliert. Dieser Arbeitsgang des Polierens kann gemäß einer Weiterbildung der Erfindung entfallen und durch einen geeigneten Schleifvorgang ersetzt werden, insbesondere durch CBN-Schleifen. In diesem Fall können Rauheiten von zum Beispiel in der Größenordnung von etwa 2 µm erzielt werden. Bei Optimierung können noch weitere Feinheiten für Rz erreicht werden, beispielsweise wenn Probleme auftreten im Bereich einer Ölkanalbohrung, einer Rille im Lager oder dergleichen. Wenn die Finish-Bearbeitung des Rotationsbauteils, insbesondere bei Kurbelwellen entfällt, führt dies ebenfalls zu einer weiteren erheblichen Reduzierung der Herstellkosten.In the case of crankshafts, the state of the art usually involves finish machining, regardless of the requirements of the crankshaft. In this case, for example, main, stroke bearings, flange and pins of the crankshaft are polished. This polishing operation can be dispensed with according to an embodiment of the invention and replaced by a suitable grinding operation, in particular by CBN grinding. In this case, roughnesses of, for example, on the order of about 2 μm can be achieved. Upon optimization, even more subtleties can be achieved for R z , for example, when problems occur in the area of an oil passage, a groove in the bearing or the like. If the finish machining of the rotary component, in particular in the case of crankshafts, is eliminated, this likewise leads to a further considerable reduction in the production costs.
Gegenstand der vorliegenden Erfindung ist weiterhin ein Rotationsbauteil, insbesondere eine Kurbelwelle, welches nach einem Verfahren der vorgenannten Art hergestellt wurde. Die in den Unteransprüchen genannten Merkmale betreffen bevorzugte Weiterbildungen der erfindungsgemäßen Aufgabenlösung. Weitere Vorteile der Erfindung ergeben sich aus der nachfolgenden Detailbeschreibung.The subject matter of the present invention is furthermore a rotary component, in particular a crankshaft, which has been produced by a method of the aforementioned type. The features mentioned in the dependent claims relate to preferred developments of Task solution according to the invention. Further advantages of the invention will become apparent from the following detailed description.
