Definitions
- the invention relates to a method for Schrupphonen the lateral surface of a bore, in which for correcting the offset of the position of the longitudinal axis and / or the angularity of the bore relative to its desired position, the lateral surface is first processed in partial section until the position of the axis of the bore to be machined equal The axis of the honing tool is, and then done the machining of the bore in full section.
- Disadvantages are both the need for a fixed bearing of the tool axis above and below the workpiece and the need for a compensation of an axial offset between the axis of the honing tool and the axis of the work spindle by a double joint.
- the invention is therefore an object of the invention to provide a method of the type mentioned, which is universally applicable.
- a compensation of the offset of the longitudinal axis of the work spindle to the longitudinal axis of the honing tool is no longer required due to the flying support of the work spindle and the fixed arrangement of the honing tool on this.
- a solid mounting of the honing tool on both sides of the bore is no longer necessary. Rather, the procedure is such that, first in the partial and then in full section, the position of the longitudinal axis of the honing tool, the position of the longitudinal axis of the work spindle, which is equal to the desired position of the bore, approaches and achieved.
- the lifting movement of the honing tool is carried out by a carriage unit, so that the work spindle is moved by the carriage unit alternately with respect to its longitudinal axis.
- the carriage unit offers, regardless of its current position, a constant guiding stability of the spindle.
- the honing spindle is in its upper end position.
- the combination of carriage unit with built-honing spindle allows in partial section a high stability of the carriage unit and in full cut high lifting speeds, as it allows a honing spindle. Due to this configuration, a cantilevered work spindle can be minimized in terms of their overall length.
- an electromechanical delivery of the honing stones takes place with defined break times during an initial partial cut.
- Switching from partial cutting to full-cut parameters can be triggered by monitoring the power consumption, since the torque increases with the full application of the cutting bars.
- This can also be the signal for retracting the carriage movement, so that it uses the lifting movement by the honing spindle and the alternating longitudinal movement is performed by the honing spindle in full section.
- a first set of honing stones is applied during the partial cutting and the full cut is carried out with a second set of honing stones.
- the Fig. 1 shows a workpiece 1, which is an engine block in the embodiment.
- This workpiece 1 comprises a plurality of holes 2, which are provided as cylinder bores and have a lateral surface 3, which is to be processed.
- Each bore 2 has a longitudinal axis M B.
- On the engine block 1 a plurality of crankshaft bearings 4 are provided in the lower region, which has a common Have axis ⁇ , namely the longitudinal axis of the crankshaft M K.
- the engine block 1 is accurately positioned on a workpiece carrier 8 by means of indexing pins 9, so that the relative position of the workpiece 1 is accurately positioned.
- the correction of the angular position of the bore axis means a correct angle recording of the workpiece. It is therefore necessary that the axes M A and M K are aligned at right angles to each other.
- a honing tool 5 which is arranged on a cantilevered work spindle 6 and includes a plurality of honing stones 7, which are provided for machining the lateral surface 3 of the holes 2.
- the work spindle 6 and thus also the honing tool 5 itself have a longitudinal axis M A , wherein from Fig. 1 It can be seen that an offset S occurs between the longitudinal axis of the work spindle M A and the longitudinal axis of the bore M B before machining by means of the honing tool 5. Apart from a few exceptions, such an offset of the axes is present, which is up to 0.3 mm.
- the longitudinal axis of the work spindle M A is deflected at a corresponding angle to get in this way in the hole 2 and the lateral surface 3 to to edit.
- a possibly assumed angle of the longitudinal axis M A may also be caused by the manufacturing tolerances of the engine block 1.
- the Fig. 2 shows a section through the engine block 1 according to Fig. 1
- the honing tool 5 is located in the bore 2 and the state is shown near the end of the machining.
- the reference numerals with those of Fig. 1 match. It is off Fig. 2
- the work spindle 6 is guided in a carriage unit 10, wherein the carriage unit 10 for a certain portion of the process (eg working in partial section) with the work spindle 6 in the longitudinal direction of the work spindle 6 and the longitudinal axis M A can be locked.
- a certain portion of the process eg working in partial section

- the Fig. 3 shows a radial section through a hole 2 and the honing tool 5 at the beginning of processing. It can be seen that the longitudinal axis M B of the bore 2 has a distance or an offset S to the longitudinal axis M A of the work spindle or of the honing tool 5. Centrally located in the honing tool 5 is a feed rod 11 which acts on the honing stones 7 via feed wedges 12. The Zustellkeile 12 can be pressed radially outward by the feed rod 11, whereby the honing stones 7 perform a radially outward movement.
- Fig. 3 shows, is at the beginning of processing, only a part of the honing tool 5 on the lateral surface 3 of the bore 2, so that with respect to the Schrupphonoperation initially a partial section takes place, in which the honing tool 5 is incomplete.
- the removal of material only part of the lateral surface 3 causes the bore center and thus the longitudinal axis of the bore M B shifts, so that the longitudinal axis of the work spindle M A and the longitudinal axis of the bore M B approach each other.
- the bore 2 is everywhere processed nationwide and thus the offset S between the axes is eliminated, the bore 2 is everywhere processed nationwide, so that the honing stones 7 rest over the entire circumference of the bore 2.
- the full section is reached, with which then the evenly honed lateral surface 3 is generated.
- the Fig. 4 shows a perspective view of a section of the bore wall or the lateral surface 3 of the cylinder bore 2.
- a section 13 can be seen with a rotary profile in the left region of the bore 2, while a Section 14 with Honprofil in the right part of the bore 2 is present. From this representation, it is clear that in the partial section that follows, only a certain section of the lateral surface 3 is machined by roughing and there is a transition from the rotary profile to the honing profile.

Abstract
Description
Die Erfindung betrifft ein Verfahren zum Schrupphonen der Mantelfläche einer Bohrung, bei dem zur Korrektur des Versatzes der Lage der Längsachse und/oder der Winkeligkeit der Bohrung gegenüber ihrer Sollposition die Mantelfläche zunächst im Partialschnitt bearbeitet wird, bis die Lage der Achse der zu bearbeitenden Bohrung gleich der Achse des Honwerkzeugs ist, und anschließend die Bearbeitung der Bohrung im Vollschnitt erfolgt.The invention relates to a method for Schrupphonen the lateral surface of a bore, in which for correcting the offset of the position of the longitudinal axis and / or the angularity of the bore relative to its desired position, the lateral surface is first processed in partial section until the position of the axis of the bore to be machined equal The axis of the honing tool is, and then done the machining of the bore in full section.
Ein solches Verfahren ist aus dem Artikel von
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu schaffen, das universeller anwendbar ist.The invention is therefore an object of the invention to provide a method of the type mentioned, which is universally applicable.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst, wobei die Achse der Arbeitsspindel gleich der Sollposition der Bohrung ist, wobei die Arbeitsspindel fliegend gelagert und das Honwerkzeug an ihrem Ende fest angeordnet ist, und wobei ferner das Honwerkzeug bei Beginn der Bearbeitung exzentrisch in die zu bearbeitende Bohrung eingeführt wird und die Bearbeitung erfolgt, bis die Längsachse der Bohrung gleich der Längsachse der Arbeitsspindel ist.This object is solved by the features of
Ein Ausgleich des Versatzes der Längsachse der Arbeitsspindel zur Längsachse des Honwerkzeugs ist infolge der fliegenden Lagerung der Arbeitsspindel und der festen Anordnung des Honwerkzeugs an dieser nicht mehr erforderlich. Ebenso ist eine feste Lagerung des Honwerkzeugs beidseitig der Bohrung nicht mehr erforderlich. Vielmehr ist der Verfahrensablauf derart, dass, zunächst im Partial- und dann im Vollschnitt, sich die Lage der Längsachse des Honwerkzeugs der Lage der Längsachse der Arbeitsspindel, die gleich der Sollposition der Bohrung ist, annähert und diese erreicht.A compensation of the offset of the longitudinal axis of the work spindle to the longitudinal axis of the honing tool is no longer required due to the flying support of the work spindle and the fixed arrangement of the honing tool on this. Likewise, a solid mounting of the honing tool on both sides of the bore is no longer necessary. Rather, the procedure is such that, first in the partial and then in full section, the position of the longitudinal axis of the honing tool, the position of the longitudinal axis of the work spindle, which is equal to the desired position of the bore, approaches and achieved.
Dadurch wird es möglich, auch Bohrungen an Werkstücken mittels Schrupphonen zu bearbeiten, die lediglich von einer Seite zugänglich sind. Dabei ist sowohl eine Korrektur der Bohrungsposition als auch eine Korrektur der Winkellage der Bohrungsachse möglich. Letzteres ist insbesondere bei Motorblöcken von erheblicher Bedeutung, da es dort in besonderem Maße auf die Winkelgenauigkeit, bezogen auf die Kurbelwellenachse, ankommt. Vorteilhafte Weiterbildungen sind in den Unteransprüchen vorgesehen.This makes it possible to edit holes on workpieces by means of roughing, which are accessible only from one side. Both a correction of the bore position and a correction of the angular position of the bore axis is possible. The latter is particularly important in engine blocks of considerable importance, since it is particularly important on the angular accuracy, based on the crankshaft axis, arrives. Advantageous developments are provided in the subclaims.
Gemäß einer bevorzugten Weiterbildung des Verfahrens ist vorgesehen, dass zumindest während der Bearbeitung des einer Schlitteneinheit abgewandt liegenden Abschnitts der Bohrung die Hubbewegung des Honwerkzeugs von einer Schlitteneinheit ausgeführt wird, so dass die Arbeitsspindel von der Schlitteneinheit alternierend bezüglich ihrer Längsachse bewegt wird. Die Schlitteneinheit bietet unabhängig von ihrer momentanen Position eine gleichbleibende Führungsstabilität der Spindel. Dabei befindet sich die Honspindel in ihrer oberen Endlage. Die verwendete Kombination von Schlitteneinheit mit aufgebauter Honspindel ermöglicht im Partialschnitt eine hohe Stabilität der Schlitteneinheit und im Vollschnitt hohe Hubgeschwindigkeiten, wie sie eine Honspindel ermöglicht. Aufgrund dieser Ausgestaltung kann eine fliegend gelagerte Arbeitsspindel bezüglich ihrer Baulänge minimiert werden. Dabei ist als minimale Baulänge zu verstehen, dass bei Erreichen des unteren Hubumkehrpunktes des Werkzeugs bei maximal üblicher Überlauflänge die Werkzeuglagerung sich kurz vor der oberen Bohrungskante befindet. Dies entspricht der minimalen Baulänge, die nicht weiter unterschritten werden kann und durch die zu honende Bohrungslänge vorgegeben ist.According to a preferred development of the method, it is provided that, at least during the processing of the section of the bore remote from a carriage unit, the lifting movement of the honing tool is carried out by a carriage unit, so that the work spindle is moved by the carriage unit alternately with respect to its longitudinal axis. The carriage unit offers, regardless of its current position, a constant guiding stability of the spindle. The honing spindle is in its upper end position. The combination of carriage unit with built-honing spindle allows in partial section a high stability of the carriage unit and in full cut high lifting speeds, as it allows a honing spindle. Due to this configuration, a cantilevered work spindle can be minimized in terms of their overall length. It should be understood as a minimum length that when reaching the lower stroke reversal point of the tool at maximum usual overflow length, the tool storage is located just before the upper edge of the hole. This corresponds to the minimum overall length, which can not be exceeded and is predetermined by the hole length to be honed.
Es wird als zweckmäßig angesehen, dass während eines zunächst erfolgenden Partialschnitts eine elektromechanische Zustellung der Honleisten mit definierten Pausenzeiten erfolgt. Das Umschalten von Partialschnitt auf Vollschnittparameter kann durch eine Überwachung der Leistungsaufnahme ausgelöst werden, da das Drehmoment mit vollflächigem Anlegen der Schneidleisten zunimmt. Dies kann auch das Signal zum Retirieren der Schlittenbewegung sein, so dass damit die Hubbewegung durch die Honspindel einsetzt und die alternierende Längsbewegung durch die Honspindel im Vollschnitt ausgeführt wird. Durch die Verwendung der Schlitteneinheit als Hubtrieb kann die Stabilität der Spindel wesentlich erhöht werden.It is considered expedient that an electromechanical delivery of the honing stones takes place with defined break times during an initial partial cut. Switching from partial cutting to full-cut parameters can be triggered by monitoring the power consumption, since the torque increases with the full application of the cutting bars. This can also be the signal for retracting the carriage movement, so that it uses the lifting movement by the honing spindle and the alternating longitudinal movement is performed by the honing spindle in full section. By using the carriage unit as a lift drive, the stability of the spindle can be significantly increased.
Während des Vollschnitthonens erfolgt eine elektromechanische Schrittzustellung, wobei die Zustellkraft, die auf die Honleisten wirkt, überwacht wird. Es ergibt sich daraus eine Kombination von weg- und kraftgesteuerter Zustellung. Gemäß einer weiteren Ausgestaltung des Verfahrens wird während des Partialschnitts ein erster Honleistensatz beaufschlagt und der Vollschnitt wird mit einem zweiten Honleistensatz durchgeführt.During full-cut honing, an electromechanical step feed occurs, with the delivery force acting on the honing stones being monitored. This results in a combination of path- and force-controlled delivery. According to a further embodiment of the method, a first set of honing stones is applied during the partial cutting and the full cut is carried out with a second set of honing stones.

Ebenso bedeutet die Korrektur der Winkellage der Bohrungsachse eine winkelgerechte Aufnahme des Werkstücks. Es ist daher erforderlich, dass die Achsen MA und MK rechtwinklig zueinander ausrichtbar sind.Likewise, the correction of the angular position of the bore axis means a correct angle recording of the workpiece. It is therefore necessary that the axes M A and M K are aligned at right angles to each other.
Über dem Werkstück 1 ist ein Honwerkzeug 5 dargestellt, das an einer fliegend gelagerten Arbeitsspindel 6 angeordnet ist und mehrere Honleisten 7 umfasst, die zur Bearbeitung der Mantelfläche 3 der Bohrungen 2 vorgesehen sind. Die Arbeitsspindel 6 und somit auch das Honwerkzeug 5 selbst besitzen eine Längsachse MA, wobei aus
Durch den Arbeitsschritt des Schrupphonens kann ein entsprechender Materialabtrag bei gleichzeitiger Eliminierung des Versatzes S erfolgen und somit die Längsachse der Bohrung MB dahingehend verlagert werden, dass diese Achse der tatsächlich im Motorblock 1 benötigten Lage exakt entspricht und somit sich der Längsachse MA annähert. Damit wird gleichzeitig die hohe Winkelgenauigkeit der Längsachse MB der Bohrung 2 der Längsachse der Kurbelwelle MK erreicht.By the step of Schrupphonens a corresponding removal of material can take place with simultaneous elimination of the offset S and thus the longitudinal axis of the bore M B be shifted to the effect that this axis of the actually required in the
Sofern der Versatz S der Längsachse der Arbeitsspindel MA zur Längsachse der Bohrung MB in einer Größe liegt, durch die das freie Einführen des Honwerkzeugs 5 in die Bohrung 2 nicht möglich ist, so wird die Längsachse der Arbeitsspindel MA in einem entsprechenden Winkel ausgelenkt, um auf diese Weise in die Bohrung 2 zu gelangen und deren Mantelfläche 3 zu bearbeiten. Während der Bearbeitung wird nicht nur der Versatz S der Längsachsen MA und MB zueinander eliminiert, sondern auch ein evtl. eingenommener Winkel der Längsachse MA der gegebenenfalls auch durch die Fertigungstoleranzen des Motorblocks 1 bedingt sein kann.If the offset S of the longitudinal axis of the work spindle M A to the longitudinal axis of the bore M B is in a size by which the free insertion of the
