Description

Die Erfindung betrifft eine Festwalzmaschine für Kurbelwellen nach dem Oberbegriff des Hauptanspruchs.The invention relates to a deep rolling machine for Crankshafts according to the preamble of the main claim.

Beim Festwalzen von Einstichen oder Radien an Kurbelwellen kann es vorkommen, daß sich die Kurbelwelle verbiegt. Zu diesem Zwecke wird im Anschluss an die Festwalzoperation die Kurbelwelle vermessen um festzustellen, ob sie einen Schlag aufweist. Das Vermessen geschieht in der Regel mit Hilfe von Messtastern, die nach der Festwalzoperation auf eines oder mehrere der Hauptlager der Kurbelwelle abgesenkt werden und elektrisch mit einem Auswertegerät in Verbindung stehen. Während der Messung führt die Kurbelwelle eine Umdrehung um ihre Längsachse aus. Durch die Zuordnung von jeweils einem Messtaster zu jedem der Hauptlager der Kurbelwelle wird auf diese Weise die Güte der festgewalzten Kurbelwelle ermittelt. Entsprechend dem Messergebnis kann sich daran eine weitere Festwalzoperation anschließen, bei welcher die Radien oder Einstiche einzelner Lagerstellen gezielt nachgewalzt werden. Das Nachwalzen kann sich über den gesamten Umfang der betreffenden Lagerstelle erstrecken, es kann aber auch nur einen Teil des Umfangs erfassen. Das Nachwalzen kann die Radien oder Einstiche an einzelnen Hauptlagern oder auch an Kurbelzapfenlagern der Kurbelwelle umfassen.When deep rolling punctures or radii Crankshafts it can happen that the crankshaft bends. For this purpose, following the Deep-rolling operation to measure the crankshaft determine if she has a hit. The Surveying is usually done with the help of Probes, which after the deep-rolling operation on a or lowered several of the main bearing of the crankshaft be and electrically with an indicator in Connection stand. During the measurement, the Crankshaft one revolution about its longitudinal axis. By the assignment of one probe to each of the Main bearing of the crankshaft is in this way the goodness determined the hard-rolled crankshaft. According to that Measurement result may be another Connect a deep rolling operation at which the radii or recesses of individual bearings selectively rolled become. The re-rolling can be over the entire circumference extend to the relevant depository, but it may capture only part of the scope. The rolling down Can the radii or punctures on individual main bearings or at crankpin bearings of the crankshaft.

An die Messgenauigkeit der Messung des Schlages werden hohe Anforderungen gestellt. So ist es zum Beispiel erforderlich, bei einer Kurbelwelle mit einer Gesamtlänge von etwa 400 mm am mittleren Hauptlager noch einen Schlag zu messen, der in der Größenordnung von 10-2 mm liegt.High demands are placed on the measurement accuracy of the measurement of the impact. For example, with a crankshaft having a total length of about 400 mm, it is necessary to measure one more stroke on the central main bearing, which is on the order of 10 -2 mm.

Ausgehend vom jeweiligen Messergebnis wird an der Festwalzmaschine über das Auswertegerät die Festwalzoperation geregelt. Üblich ist es, eine Mehrzahl von Messtastern, entsprechend jedem Hauptlager, entlang der Kurbelwelle anzuordnen. Durch die gegenseitigen Abstände, welche die Messtaster voneinander haben, ist die Anordnung jeweils nur für einen bestimmten Typ einer Kurbelwelle geeignet. Moderne Festwalzmaschinen für Kurbelwellen sind allerdings so ausgelegt, daß mehrere Typen von Kurbelwellen nacheinander bearbeitet werden können. Das bedingt aber, daß die Einstellung der Messtaster von Kurbelwellentyp zu Kurbelwellentyp angepasst werden muss. Beispielsweise erfordert das Festwalzen einer Kurbelwelle für einen 3-Zylinder-Motor eine geringere Anzahl an Messtastern als das Festwalzen von Kurbelwellen für Motoren, welche eine größere Anzahl von Zylindern haben. Dementsprechend muss die Festwalzmaschine für die Kurbelwellen jedes Mal umgerüstet werden, wenn darauf unterschiedliche Typen von Kurbelwellen bearbeitet werden sollen. Abgesehen von dem damit einhergehenden Wechsel der Festwalzwerkzeuge müssen jedesmal die Messtaster mit der erforderlichen Genauigkeit neu eingerichtet werden, damit die Festwalzoperation zum Erfolg führt.Starting from the respective measurement result is at the Hard rolling machine via the evaluation device Fixed rolling operation. It is common, a majority of probes, corresponding to each main bearing, along to arrange the crankshaft. By the mutual Distances that the probes have from each other is the arrangement in each case only for a certain type of Crankshaft suitable. Modern deep rolling machines for However, crankshafts are designed so that several Types of crankshafts are machined sequentially can. This requires, however, that the setting of Probe from crankshaft type to crankshaft type must be adjusted. For example, that requires Deep rolling a crankshaft for a 3-cylinder engine a smaller number of probes than the deep rolling of crankshafts for engines, which require a larger number of cylinders. Accordingly, the Deep rolling machine for the crankshafts every time be upgraded if different types of Crankshafts are to be processed. Except for the concomitant change of deep-rolling tools must each time the probes with the required Accuracy will be refurbished so that the Deep rolling operation leads to success.

Daraus ergibt sich die Aufgabe für die vorliegende Erfindung, entsprechend dem jeweiligen Typ der festzuwalzenden Kurbelwelle Messtaster in erforderlicher Anzahl und vorbereiteter Anordnung auswechselbar an der Festwalzmaschine anzubringen. Dabei soll neben der geforderten Messgenauigkeit zugleich gewährleistet sein, daß die Vielfachverbindung der Messtaster mit dem Auswertegerät mit großer Schonung und Zuverlässigkeit sowie in kürzester Zeit hergestellt werden kann. Schließlich soll die Umrüstzeit von einer Messtastergruppe auf die andere so kurz wie möglich, und das Anbringen der Messtaster so leichtgängig wie möglich sein.This results in the task for the present Invention according to the respective type of to be tightened crankshaft probe in required Number and prepared arrangement replaceable at the To install a deep rolling machine. It should in addition to the be guaranteed at the same time required measurement accuracy, that the multiple connection of the probe with the Evaluation unit with great protection and reliability as well as can be produced in a short time. Finally, the changeover from a Probe group on the other as short as possible, and attaching the probes as smoothly as possible be.

Die Aufgabe wird mit den Merkmalen des Hauptanspruchs gelöst. Dort ist eine Messtaster-Brücke vorgesehen, auf welcher entsprechend der Anzahl der zu vermessenden Hauptlager eine Mehrzahl von Messtastern vorgesehen ist, die in gegenseitigem Abstand zueinander angeordnet sind. Die Messtaster-Brücke kann über eine Schnellkupplung mit dem freien Ende des Armes verbunden werden, der dazu vorgesehen ist, die Messtaster mit der Kurbelwelle in Eingriff zu bringen. Die Schnellkupplung ist so ausgestaltet, daß daneben zugleich die Kabelverbindung hergestellt werden kann, über welche die einzelnen Messtaster mit dem Auswertegerät in Verbindung stehen. Im vorliegenden Fall ist die Kabelverbindung ein mehrpoliger Stecker, der ein sorgfältiges und hochgenaues miteinander Verbinden der einzelnen Kabel sicherstellt, die jedem Messtaster zugeordnet sind. Die Schnellkupplung gewährleistet, daß die Messbrücke ohne Verkanten und leichtgängig an der Festwalzmaschine angebracht werden kann. Zugleich erfolgt das Kuppeln der Messtaster mit dem Auswertegerät unter größtmöglicher Schonung der Steckverbindung. Jedem Kurbelwellentyp ist eine eigene Messtaster-Brücke zugeordnet, auf welcher die einzelnen Messtaster typengerecht angebracht sind. Durch die schnelle Austauschbarkeit einzelner Messtaster-Brücken kann die Rüstzeit der Festwalzmaschine wesentlich verringert werden.The task comes with the characteristics of Main claim solved. There is a probe bridge provided on which according to the number of measuring main bearing a plurality of probes is provided, which are at a mutual distance from each other are arranged. The probe bridge can have a Quick coupling connected to the free end of the arm which is intended to be the touch probe with the Engage crankshaft. The quick coupling is designed in such a way that beside it at the same time the Cable connection can be made, over which the single probe connected to the evaluation device stand. In the present case, the cable connection is a multipolar plug, which is a meticulous and highly accurate Ensuring interconnection of each cable ensures which are assigned to each probe. The quick coupling ensures that the bridge without jamming and be easily attached to the deep rolling machine can. At the same time, the measuring probes are coupled with the Evaluation device with the utmost protection of the Plug connection. Each type of crankshaft is its own Assigned to the probe bridge on which the individual Probe are mounted according to the type. By the fast interchangeability of individual probe bridges can the set-up of the deep rolling machine essential be reduced.

Besonders vorteilhaft ist die Ausbildung der Schnellkupplung als Stellhülse, in welche zum Befestigen von Messtastern ein Zapfen einführbar ist, der seinerseits Teil der Messtaster-Brücke ist und durch achsiales Verschieben einer Schalthülse entriegelt werden kann. Stellhülsen der genannten Art sind beispielsweise aus der DIN 55 058 bekannt. Über die aus der Norm bekannten Stellhülsen werden Werkzeuge mit den Spindelköpfen von Werkzeugmaschinen verbunden. In Anlehnung an die DIN Norm wurden die Stellhülsen beziehungsweise Werkzeughalter in einer Weise weiterentwickelt, daß sie ohne Hilfswerkzeuge schnell wechselbar sind und durch Einstoßen in die Spindel der Werkzeugmaschine verriegelt werden. Die Entriegelung erfolgt durch achsiales Verschieben einer Schalthülse. Ein entsprechendes System ist unter der Typenbezeichnung ASBVA einer Firmenschrift der Firma Otto Bilz Werkzeugfabrik GmbH & Co., 73760 Ostfildern, bekannt geworden.Particularly advantageous is the training of Quick coupling as adjusting sleeve, in which to attach of probes a pin is insertable, the in turn is part of the probe bridge and through axial displacement of a shift sleeve are unlocked can. Adjusting sleeves of the type mentioned are, for example known from DIN 55 058. About the out of the norm known adjusting sleeves are tools with the Spindle heads connected by machine tools. In Based on the DIN standard were the adjusting sleeves or tool holder in a way evolved that they quickly without auxiliary tools are changeable and by pushing into the spindle of Machine tool to be locked. The unlocking takes place by axial displacement of a switching sleeve. A corresponding system is under the type designation ASBVA a company publication of the company Otto Bilz Werkzeugfabrik GmbH & Co., 73760 Ostfildern, known become.

Ein sicheres Kuppeln und Entkuppeln der Messtaster-Brücke mit der Festwalzmaschine wird erzielt, wenn zwei Arme in gleicher geometrischer Anordnung mit der Welle drehfest verbunden sind, die für das In-Eingriff-Bringen der Messtaster mit der Kurbelwelle an der Festwalzmaschine vorgesehen ist. Jedem der beiden Arme ist sodann jeweils auch eine Stellhülse zugeordnet. Die freien Enden der beiden Arme sind über eine Platte miteinander verbunden. Seitlich neben den Armen sind die Stellhülsen für die Schnellkupplung auf der Platte befestigt. Safe coupling and decoupling of the probe bridge with the deep rolling machine is achieved when two arms in the same geometric arrangement with the shaft rotation are connected, which are responsible for engaging the Probe with the crankshaft on the deep rolling machine is provided. Each of the two arms is then each also assigned an adjusting sleeve. The free ends of the Both arms are connected by a plate. Laterally next to the arms are the adjusting sleeves for the Quick coupling fixed to the plate.

Damit das Anbringen der Messtaster-Brücke an der Festwalzmaschine möglichst ohne Verkanten und daher leichtgängig erfolgen kann, ist eine der Stellhülsen über ein Gelenk mit der Platte verbunden, die ihrerseits die Enden der beiden Arme miteinander verbindet. Durch das Gelenk können zugleich auch gewisse Fertigungstoleranzen aufgefangen werden, die bei der Herstellung einer Messtaster-Brücke unvermeidbar sind. Durch das Gelenk wird weitgehend ausgeschlossen, daß sich die Messtaster-Brücke beim Anbringen an der Festwalzmaschine verkanten kann, wodurch die Leichtgängigkeit der Verbindung als auch die Messgenauigkeit gewährleistet ist. Zur Schonung der elektrischen Kontakte sind Teile der lösbaren Steckverbindung, die zum Auswertegerät führen, ebenfalls mit der Platte fest verbunden.Thus attaching the probe bridge to the Hard rolling machine as possible without tilting and therefore can be done smoothly, is one of the adjusting sleeves over a joint connected to the plate, which in turn the Ends of the two arms connects. By the Joint can also have certain manufacturing tolerances be caught in the production of a Probe bridge are unavoidable. Through the joint is largely excluded that the probe bridge when attaching to the deep rolling machine tilt can, thereby reducing the ease of the connection as also the measuring accuracy is guaranteed. For the sake of protection The electrical contacts are parts of the detachable Plug connection leading to the evaluation, also firmly connected to the plate.

Wie an sich üblich, steht jeder Messtaster in der Stellung des Eingriffs mit der Kurbelwellen senkrecht. Während des Festwalzens der Kurbelwellen werden die Messtaster außer Eingriff geschwenkt und nehmen dabei eine annähernd horizontale Lage ein. In dieser ausgeschwenkten Stellung der Messtaster können die Festwalzwerkzeuge ungehindert die Radien oder Einstiche der Kurbelwelle festwalzen.As usual, each probe is in the Position of engagement with the crankshaft vertical. During the deep rolling of the crankshafts, the The probe is disengaged and take it an approximately horizontal position. In this swung out position of the probe, the Deep rolling tools unhindered the radii or recesses firmly roll the crankshaft.

The Probes 4 are at mutual distances 5, according to the arrangement of the main bearing 3, with their attached to a probe bridge 6 upper ends. The Probe bridge 6 consists of a profile strip 7, in whose grooves 8 slidable prism stones 9 attached are. At each two prismatic stones 9 is a probe 4 bolted with its upper end.

Die Profilleiste 7 ist auf einer Platte 10 befestigt. Auf der die Profilleiste 7 tragenden Oberseite 11 weist die Platte 10 einen Handgriff 12 auf. Auf der der Oberseite 11 gegenüberliegenden rückwärtigen Oberseite 13 der Platte 10 (Fig. 2) springen zwei Zapfen 14 und 15 senkrecht hervor (Fig. 5 und 6). Die beiden Zapfen 14 und 15 haben einen gegenseitigen Abstand voneinander, welcher dem Abstand 16 entspricht, den die beiden Schnittlinien J-J und H-H voneinander haben (Fig. 1). Die horizontale Höhenlage der beiden Zapfen 14 und 15 auf der Platte 10 ist gleich und erstreckt sich parallel zur Längsachse 2 der Kurbelwelle 1; in der Fig. 1 ist das durch die jeweiligen Befestigungen 17 und 18 für die Zapfen 14 und 15 erkennbar. Während die Befestigung 17 für den Zapfen 14 in der Fig. 5 als Schraubverbindung 19 zu erkennen ist, ist die Befestigung 18 für den Zapfen 15 an der Platte 10 als Gelenk 20 ausgestaltet. Das Gelenk 20 wird von einer Platte 21 und Schrauben 22 an der Platte 10 gehalten; es ist in begrenztem Umfang nach allen Richtungen bewegbar.The profile strip 7 is mounted on a plate 10. On the profile strip 7 carrying top 11 has the Plate 10 on a handle 12. On the top 11 opposite rear top 13 of Plate 10 (Fig. 2) jump two pins 14 and 15th perpendicular (Figs. 5 and 6). The two pins 14 and 15 have a mutual distance from each other, which the distance 16 corresponds to the two cutting lines J-J and H-H have each other (Fig. 1). The horizontal one Altitude of the two pins 14 and 15 on the plate 10th is equal and extends parallel to the longitudinal axis. 2 the crankshaft 1; in Fig. 1 is through the respective fasteners 17 and 18 for the pins 14 and 15 recognizable. While the attachment 17 for the pin 14 in FIG. 5 as a screw 19 to recognize is the attachment 18 for the pin 15 at the Plate 10 designed as a joint 20. The joint 20 becomes from a plate 21 and screws 22 on the plate 10th held; it is to a limited extent after all Movable directions.

Die Zapfen 14 und 15 greifen jeweils in gleichartige Stellhülsen 23 ein, die über Schrauben 24, welche jeweils mit einer Scheibe 25 unterlegt sind, an einer Leiste 26 befestigt sind. Die Leiste 26 verbindet die äußeren freien Enden 27 von zwei Armen 28 miteinander, die auf einer Welle 29 drehfest und in gegenseitigem Abstand 30 voneinander befestigt sind.The pins 14 and 15 each engage in similar Adjusting sleeves 23, which via screws 24, which respectively are underlaid with a disk 25, on a bar 26th are attached. The bar 26 connects the outer free ends 27 of two arms 28 together, on a shaft 29 rotatably and at a mutual distance 30th are attached to each other.

Ebenso wie die beiden Zapfen 14 und 15 sind die Stellhülsen 23 Teile von zwei Schnellkupplungen 31, über die die Messtaster-Brücke 6 an die Leiste 26 und somit an die Arme 28 und die Welle 29 der Festwalzmaschine 41 angeschlossen werden kann. Das Anschließen der Messtaster-Brücke 6 an die Festwalzmaschine 41 erfolgt durch einfaches Einführen der Zapfen 14 und 15 in die jeweiligen Stellhülsen 23. Konisch ausgestaltete Enden 42 erleichtern das Einführen der Zapfen 14 und 15 in die Stellhülsen 23; Bünde 43 auf ihrem Schaft 44 gewährleisten einen passgenauen Sitz und Leichtgängigkeit der Zapfen 14 und 15 innerhalb der Stellhülsen 23. Davon zu lösen ist die Messtaster-Brücke 6 über Schalthülsen 32, welche ihrerseits achsial beweglich auf dem äußeren Abschnitt der Stellhülsen 23 geführt sind.

Die Fig. 3 zeigt die Messtaster-Brücke 6 jeweils in der Arbeits- und in der Ruhestellung. In der Arbeitsstellung auf der linken Hälfte der Fig. 3 ist der Messtaster 4 auf die Kurbelwelle 1 abgesenkt und steht nahezu senkrecht auf einem der Hauptlager 3. Im rechten Teil der Fig. 3 befindet sich die Messtaster-Brücke 6 in der Ruhestellung. Beim Übergang von der Arbeits- in die Ruhestellung beschreibt die Spitze des Messtasters 4 einen Bogen 39. Eine Stützkette 40 bewahrt die aus dem Teil 37 des Kabelsteckers 35 austretenden Kabel (nicht gezeigt) davor, beim Verschwenken des Messtasters 4 entlang des Bogens 39 Schaden zu nehmen. Die Welle 29, mit ihren Armen 28 und der die Enden der Arme 28 verbindenden Leiste 26 sind Teile der Festwalzmaschine 41, welche beständig daran verbleiben. Fig. 3 shows the probe bridge 6 respectively in the At work and at rest. In the working position on the left half of Fig. 3, the probe 4 is on the crankshaft 1 is lowered and is almost vertical on one of the main bearings 3. In the right part of FIG. 3 is the probe bridge 6 in the Rest. In the transition from work to work Rest position describes the tip of the probe 4 a bow 39. A support chain 40 preserves the from the Part 37 of the cable connector 35 leaking cable (not shown) before, during pivoting of the probe 4 to take damage along the arch 39. The wave 29, with their arms 28 and the ends of the arms 28 connecting bar 26 are parts of the deep rolling machine 41, which persist in it.
