Description

Spindelstock Headstock
Die vorliegende Erfindung betrifft einen Spindelstock fur Werkzeugmaschinen; mit einem Spindelteil und einem Gehauseteil.The present invention relates to a headstock for machine tools; with a spindle part and a housing part.
Der Spmdelstock ist emer der mehreren ko¬ stenaufwendigen Baugruppen einer Werkzeugmaschine. Abhan¬ gig von der jeweiligen Bearbeitungsart und Ausfuhrung der Werkzeugmaschine wurden bis anhin Spindelstocke unter¬ schiedlich ausgebildet, so dass bei der Herstellung auf¬ grund einer verhältnismässig kleinen Stuckzahl gleich ausgebildeter Spindelstocke die Kosten fur einen einzel¬ nen Spmdelstock entsprechend hoch gewesen sind. Weiter ist bisher insbesondere der Spindelteil emes Spindel¬ stockes em verhältnismässig aufwendig und damit wieder teuer herzustellender Gegenstand gewesen.The Spmdelstock is one of the several costly assemblies of a machine tool. Depending on the particular type of processing and design of the machine tool, headstocks have so far been designed differently, so that the costs for a single headstock have been correspondingly high during manufacture due to a relatively small number of headstocks of the same design. Furthermore, in particular the spindle part emes a spindle stock has been relatively complex and therefore expensive to manufacture again.
Ziel der Erfindung ist, die angeführten Nach¬ teile zu beheben und einen Spmdelstock zu schaffen, der einfach aufgebaut und kostengünstig ist, und der fur eine Vielzahl von Anwendungen praktisch unverändert eingesetzt werden kann.The aim of the invention is to remedy the disadvantages mentioned and to create an exercise stick which is simple in construction and inexpensive and which can be used practically unchanged for a large number of applications.
Der erfindungsgemasse Spmdelstock ist da¬ durch gekennzeichnet, dass der Spindelteil und der Gehau- seteil aus j e einem Rohrstuck gebildet sind, wobei der Spindelteil aus einem zylindrischen Rohrstuck besteht, der im Gehauseteil drehbar gelagert ist.The inventive spindle stick is characterized in that the spindle part and the housing part are each formed from a pipe piece, the spindle part consisting of a cylindrical pipe piece which is rotatably mounted in the housing part.
Die Vorteile des erfindungsgemässen Spindel- stockes smd insbesondere darin zu sehen, dass er aus einfach herzustellenden, robusten Teilen aufgebaut ist und mit ausserst kleinen Aenderungen, falls überhaupt notwendig, fur jedwelche Werkzeugmaschine, bzw. Bearbei¬ tungsart praktisch universell eingesetzt werden kann. Im folgenden wird die Erfindung anhand von mehrere Ausfuhrungswege darstellenden Zeichnungen bei¬ spielsweise naher erläutert. Figur 1 zeigt eme Teilansicht eines Spindel- stockes m Richtung des Pfeiles A der Fig. 2, undThe advantages of the headstock according to the invention can be seen, in particular, in the fact that it is constructed from simple, robust parts and, with very small changes, if at all necessary, can be used practically universally for any machine tool or type of machining. In the following, the invention is explained in more detail, for example, with the aid of drawings showing several embodiments. FIG. 1 shows a partial view of a headstock in the direction of arrow A in FIG. 2, and
Figur 2 zeigt einen erfindungsgemäss ausge¬ bildeten Spmdelstock, der in der oberen Hälfte der Figur 2 im Schnitt und m der unteren Hälfte in einer Seitenan¬ sicht gezeichnet ist.FIG. 2 shows an exercise stick designed according to the invention, which is drawn in section in the upper half of FIG. 2 and in a side view in the lower half.
Der Spmdelstock weist emen Spindelteil 1 und einen Gehauseteil 2 auf. Dabei ist der Spindelteil 1 über Spmdellager 3,4,5,6,7,8 drehbar im Gehauseteil 2 gelagert. Der Spindelteil 1 besteht lediglich aus einem Rohrstuck. Er weist somit eme glattwandige Aussenflache und eme glattwandige Innenflache auf. Insbesondere weist der Spindelteil 1 keine Bunde, Schultern, etc. auf, die eine besondere Bearbeitung, z.B. durch Drehen bei der Herstellung benotigen wurden.The Spmdelstock has a spindle part 1 and a housing part 2. The spindle part 1 is rotatably mounted in the housing part 2 via spindle bearings 3, 4, 5, 6, 7, 8. The spindle part 1 consists only of a piece of pipe. It thus has a smooth-walled outer surface and a smooth-walled inner surface. In particular, the spindle part 1 has no collars, shoulders, etc. that require special processing, e.g. by turning during manufacture.
Der Gehauseteil 2 ist ebenfalls ein einfaches Rohrstuck, welches, wie aus der Fig. 2 ersichtlich, mit emem minimalen Arbeitsaufwand hergestellt werden kann. Bei der mit ausgezogenen Linien gezeigten Ausfuhrung erfolgt der Antrieb des Spmdelteiles 1 über einen Poly-V, Keil- oder Zahnriemenantrieb von einem nicht gezeichneten Antriebsmotor her. Ersichtlich ist die Riemenscheibe 18, die über eme an sich bekannte Klemman¬ ordnung mit einem Klemmring 19 und Klemmgliedern 32 mit dem Spindelteil 1 drehfest verbunden ist. Die Bezugszif¬ fern 20, 21 bezeichnen die Riemen des Antriebs. Bei ihrem oberen, rechten Ende gemass Fig. 2 steht die Riemenschei¬ be 18 in Antriebsverbindung mit emem Drehgeber 22 be¬ kannter Ausbildung, wobei die Kraftübertragung über Zahn- rader oder wieder emem Riementeil 23 erfolgt.The housing part 2 is also a simple piece of pipe which, as can be seen from FIG. 2, can be produced with a minimal amount of work. In the embodiment shown with solid lines, the spool part 1 is driven by a poly-V, V-belt or toothed belt drive from a drive motor, not shown. The pulley 18 can be seen, which is connected in a rotationally fixed manner to the spindle part 1 via a known clamping arrangement with a clamping ring 19 and clamping members 32. The reference numerals 20, 21 denote the belts of the drive. At its upper, right-hand end according to FIG. 2, the pulley 18 is in drive connection with a known encoder 22, the force being transmitted via gear wheels or a belt part 23 again.
Weiter ist bei der mit ausgezogener Linien gezeigten Ausfuhrung beim rechtsliegenden Spmdelteilende 11 em Spmdelflansch 13 aufgeschrumpft. Der Spindel¬ flansch 13 steht somit in einem Pressverbund mit dem Spindelteil 1. Die Ausbildung des Spmdelflansches 13 kann somit frei gewählt werden, ohne dass das Spindelteil 11 angepasst werden müsste. So ist es möglich, die Grosse des Ξpindelflansches zu variieren, eme zylindrische Auf¬ nahme einzusetzen, aber auch einen Fraskonus oder andere Aufnahmen fur z.B. ISO-Aufnahmen zu integrieren. Der Spindelflansch 13 weist innen mehrere Innenumfangsrillen 24 auf. Diese dienen zur Aufnahme einer unter Druck ste¬ henden Hydraulikflussigkeit, wenn der Spindelflansch 13 vom Spmdelendteil entfernt werden muss.Furthermore, in the embodiment shown with solid lines, at the right end of the part 11 of the part 13, the part flange 13 is shrunk. The spindle flange 13 is thus in a press connection with the spindle part 1. The configuration of the spindle flange 13 can thus be chosen freely without the spindle part 11 having to be adapted. So it is possible the big one to vary the spindle flange, to use a cylindrical receptacle, but also to integrate a milling cone or other receptacles for, for example, ISO receptacles. The spindle flange 13 has a plurality of inner circumferential grooves 24 on the inside. These serve to hold a hydraulic fluid under pressure when the spindle flange 13 has to be removed from the spindle end part.
Der rohrförmige Gehauseteil 2 ist von einer Hülse 14 umringt. Der Zwischenraum 15 zwischen der Hülse 14 und dem Gehauseteil 2 ist mit einem Stoff gefüllt, der die Vibrationen dampft, z.B. Blei oder em emvibrierter Quarz-Sand. Durch diese Vibrationsdampfung werden Eigen¬ schwingungen des Spmdelstockes im Falle emer Unwucht oder durch Zerspannungsemflusse stark reduziert. Das Montieren des insgesamt rohrförmigenThe tubular housing part 2 is surrounded by a sleeve 14. The space 15 between the sleeve 14 and the housing part 2 is filled with a substance which dampens the vibrations, e.g. Lead or emvibrated quartz sand. This vibration damping greatly reduces the natural vibrations of the baffle stick in the event of an imbalance or due to cutting effects. Assembling the overall tubular
Spmdelstockes auf der jeweiligen Werkzeugmaschine er¬ folgt durch Klemmbriden 16, 17.Spmdelstockes on the respective machine tool follows by clamping brackets 16, 17.
Bei der in Fig. 2 mit ausgezogenen Linien ge¬ zeichneten Ausfuhrung erfolgt der Antrieb des Spindel- teils 1 links über einen Riementrieb 18, 20, 21 und der Spmdelflansch 13 ist an der rechten Seite des Spindel- teils 1 angeordnet.In the embodiment shown in solid lines in FIG. 2, the spindle part 1 is driven on the left via a belt drive 18, 20, 21 and the spindle flange 13 is arranged on the right side of the spindle part 1.
Eine weitere Ausfuhrungsmoglichkeit, die bei¬ spielsweise bei einer Uebertragung vor grösseren Momenten zur Anwendung kommt, ist mit strichlmierten Linien ge¬ zeichnet. Der Antrieb des Spmdelteils 1 erfolgt in die¬ sem Fall über em Zahnradgetriebe, von welchem das mit dem Spindelteil 1 über das Klemmsystem 33 verbundene Zahnrad 25 gezeichnet ist. Es ist ersichtlich, dass nun die Kraftübertragung auf den Spindelteil 1 nicht am Ende, sondern m der Mitte erfolgt. Damit kann em Spindel¬ flansch 12 am linken Ende des Spmdelteils 1 montiert werden. Wie es insbesondere bei Mittenantriebsmaschinen, Oelfeldmaschmen, usw. wo Doppelfutter oder andere Auf- nahmen verwendet werden üblich ist, kann an beiαen Enden des Spmdelteils 1 jeweils em Spmdelflansch 12, 13 fur das zu befestigende Spannmittel angeordnet werden. Um nun den verschiedensten Anwendungen ge¬ recht zu werden, ist der Spindelteil 1 an zwei Lagerstel¬ len im Gehauseteil 2 gelagert, wobei bei jeder Lagerstel¬ le eme wahlbare Anzahl Lagereinheiten vorhanden ist, de- ren Position in der Lagerstelle zudem wahlbar ist.Another possible embodiment, which is used, for example, for transmission before larger moments, is drawn with dashed lines. In this case, the spindle part 1 is driven via a gear transmission, of which the gear 25 connected to the spindle part 1 via the clamping system 33 is drawn. It can be seen that the force is now transmitted to the spindle part 1 not in the end but in the middle. This enables a spindle flange 12 to be mounted on the left end of the spindle part 1. As is customary, in particular, in center drive machines, oil field machines, etc., where double chucks or other receptacles are used, in each case one spindle flange 12, 13 for the clamping means to be fastened can be arranged at both ends of the spindle part 1. In order to do justice to the most varied of applications, the spindle part 1 is mounted on two bearing points in the housing part 2, with each bearing point having a selectable number of bearing units, the position of which in the bearing point can also be selected.
Bei der mit ausgezogenen Linien dargestellten Ausfuhrung des Spmdelstockes (Fig. 2), also im Falle ei¬ nes Riementriebs 18, 20, 21 und einem Spindelflansch 13 beim rechten Ende des Spmdelteiles 1 befinden sich bei der Lagerstelle links beispielhaft zwei Kugellager 3, 4 und bei der Lagerstelle rechts vier Kugellager 5,6,7 und 8.In the case of the embodiment of the spindle stick (FIG. 2) shown in solid lines, that is to say in the case of a belt drive 18, 20, 21 and a spindle flange 13 at the right end of the spindle part 1, two ball bearings 3, 4 and at the bearing point on the right four ball bearings 5,6,7 and 8.
Die Arretierung der Lagereinheiten erfolgt beispielhaft durch eme mit der Bezugsziffer 26 angedeu- tete Klemmeinrichtung.The bearing units are locked, for example, by a clamping device indicated by reference number 26.
Als maximale Anzahl Lagereinheiten smd bei der rechts liegenden Lagerstelle, die den höheren Bela¬ stungen als die links liegende Lagerstelle ausgesetzt ist, vier Spindellager 5,6,7 und 8 angeordnet. Diese ma- ximale Anzahl kann nun, wie es bei der links liegendenFour spindle bearings 5, 6, 7 and 8 are arranged as the maximum number of bearing units smd at the bearing on the right, which is exposed to the higher loads than the bearing on the left. This maximum number can now, as with the one on the left
Lagerstelle ersichtlich ist vermindert werden, indem le¬ diglich zwei Spindellager 3 und 4 vorhanden smd. In dem sich damit ergebende Leerraum ist eme Stutzhulse 9 mit hier einer Lange von zwei Lagerbreiten angeordnet. Es ist ersichtlich, dass diese zwei Lagereinheiten 3 und 4 auch in emem Abstand voneinander angeordnet sein können, in welchem Fall dann die Hülse 9 zwischen den zwei Lagerein¬ heiten 3 und 4 eingeschoben ist, wobei zusätzlich eme (nicht gezeichnete) Innenhulse unmittelbar auf dem Spin- delteil 1 sitzt. Eine solche Anordnung wird beispielswei¬ se bei einem Mittenantrieb (Zahnrad 25) gewählt. Die An¬ zahl Lagereinheiten und der Embauort derselben innerhalb der Lagerstellen ist damit frei wahlbar.The bearing point can be reduced by only having two spindle bearings 3 and 4. In the resulting empty space, a support sleeve 9 with a length of two storage widths is arranged here. It can be seen that these two bearing units 3 and 4 can also be arranged at a distance from one another, in which case the sleeve 9 is then inserted between the two bearing units 3 and 4, with an additional inner sleeve (not shown) directly on the Spindle part 1 sits. Such an arrangement is selected, for example, in the case of a center drive (gear wheel 25). The number of storage units and the place where they are built within the storage locations is thus freely selectable.
Damit lasst sich der Spmdelstock nur durch die Wahl der Lagereinheiten fur einen Antrieb mittels ei¬ nem Riemenantrieb oder fur einen Mittenantrieb über em Zahnradgetriebe, fur eme Leichtbaulagerung oder eine Schwerbaulagerung mit kleinster Aenderung des Aufbaus ausoilden.Thus, the beater can only be selected by the choice of the bearing units for a drive by means of a belt drive or for a center drive via a gear transmission, for a lightweight construction or Train heavy-duty storage with the smallest change in the structure.
Beim rechten Ende des Spmdelteils 1 ist eme dreifache Labyrinthdichtung vorhanden, die durch die Rmgteile 27, 28 gebildet ist, wobei der Ringteil 27 mit dem Spindelteil 1 und der Rmgteil 28 beispielsweise über Schraubbolzen 29 mit dem Gehauseteil 2 verbunden smd.At the right end of the spindle part 1 there is a triple labyrinth seal which is formed by the ring parts 27, 28, the ring part 27 being connected to the spindle part 1 and the ring part 28, for example via screw bolts 29, to the housing part 2.
Im Spindelflansch 13 smd Gewmdelocher 30 zur Verbindung mit emem jeweiligen Arbeitstell, z.B. Spannfutter vorhanden. Die Gewindelocher 31 werden beim Abpressen des Spindelflansches 1 benutzt. In the spindle flange 13 smd punch hole 30 for connection to a respective work place, e.g. Chuck available. The threaded holes 31 are used when pressing off the spindle flange 1.
