Abstract

The invention for which a patent has been applied for here is a compound-bed construction for steep-bed lathes. The headstock (1) is structurally connected to the lathe bed (2) and the stand (3) and bolted together to form a single unit. The arrangement and dimensioning of the joining bolts is in accordance with the overall construction. Compared to the previous lathe constructions, in which the headstock is suspended or stands freely on the bed body, this construction makes a decisive improvement to the static and dynamic rigidity of the headstock. Vibrations and oscillations of the spindle nose, which could result in the work-driving spindle being offset out of its zero position, are virtually eliminated. Advantages of this lathe construction are: - high rigidity of the headstock - high truth of running of the work-driving spindle at high speeds and even in the case of unbalanced workpieces - high cutting speeds are possible, giving increased capacity while lowering tool costs. <IMAGE>

Description

■tnt\Jtk<\*\■ tnt \ Jtk <\ * \

Der Spindelstock (1) ist mit dem Drehbankbett (2) und der Grundkonsole (3) zu einer Einheit fest verschraubt, wodurch sich eine besonders hohe Steifigkeit und Vibrationsfreiheit des Spindel kopfes ergibt. Die Abbildung (1) zeigt die Steilbett - Jrehmaschine in der Vorderansicht, auch dort sichtbar der Spindelkopf (1), das Steilbett (2) und die Grundkonsole (3).The headstock (1) is firmly screwed to the lathe bed (2) and the base bracket (3) to form a unit, whereby particularly high rigidity and freedom from vibration of the spindle head results. The figure (1) shows the steep bed lathe in the front view, also visible there the spindle head (1), the steep bed (2) and the base bracket (3).

Bei allen bisherigen Drehmaschinen, ganz gleich, ob es sich hier um Horizontal bett - Drehmaschinen oder um andere Steilbett Drehmaschinen handelt, bei all diesen Drehmaschinen steht oder hängt der Spindelstock jeweils frei auf dem Bettkörper.With all previous lathes, regardless of whether it is here about horizontal bed lathes or other steep bed lathes acts, with all these lathes the headstock stands or hangs freely on the bed body.

Beim überschreiten einer bestimmten Belastungsgrenze wird der Spindelkopf in Vibrationen versetzt, das heißt, abhängig von der jeweiligen Belastung, wird die Dreharbeitsspindel mehr oder weniger weit aus ihrer absoluten Nullposition heraus versetzt. If a certain load limit is exceeded, the The spindle head is set in vibration, that is, depending on the respective load, the lathe work spindle becomes larger or offset less from their absolute zero position.

Bei der hier zum Patent angemeldeten Verbundbett - Konstruktion wird die statische und dynamische Steifigkeit des SpindelStockes so erhöht, daß Vibrationen des Spindel Stockes somit praktisch ausgeschlossen werden.With the composite bed construction for which a patent is pending, the static and dynamic rigidity of the spindle stock so increased that vibrations of the spindle stock are practically excluded.

Aufgrund der hier zum Patent angemeldeten Verbundbett - Konstruktion ergibt sich wegen der besonders hohen Steifigkeit des Spindelstockes eine hohe Rundlaufgenauigkeit der Arbeitsspindel bei höheren Drehzahlen. Hierdurch kann mit höheren Schnittgeschwindigkeiten bearbeitet werden. Dies bedeutet eine Steigerung'der Leistungsfähigkeit der Drehmaschine bei gleichzeitiger Senkung der Werkzeugkosten. Because of the composite bed construction for which a patent is pending Because of the particularly high rigidity of the headstock, the work spindle has a high concentricity higher speeds. This allows machining at higher cutting speeds. This means an increase in performance of the lathe while reducing tool costs.

zum Brief vom 1. 9. 1983 an Deutsches Patentamton the letter dated September 1, 1983 to the German Patent Office

Die Verbundbett - Konstruktion hat theoretisch Gültigkeit für jede denkbare Steilbett Drehbankgröße, gebaut werden sollen Steilbett - Drehmaschinen von 15o - 8oo mm Spitzenhöhe. Gerade bei schweren Maschinen bringt diese Verbundbett Konstruktion für die hier Patentschutz beantragt wird, ganz besondere Vorteile m i t s i c h.The composite bed construction is theoretically valid for every conceivable steep bed lathe size that can be built steep bed lathes with a center height of 150 - 8oo mm should be used. This composite bed construction is particularly useful for heavy machinery for which patent protection is applied for here, very special advantages with s i c h.

Aufgrund der hohen Steifigkeit dieser Maschinenkonstruktion sind höhere Unwucht einzelner Drehteile zugelassen, als dies bei frei aufgehängten Spindel köpfen der Fall sein kann, weil ja eben Spindelkopf, Drehbankbett und Grundkonsole zu einer Einheit verschraubt werden.Due to the high rigidity of this machine construction, higher unbalance of individual turned parts are permitted than this This can be the case with freely suspended spindle heads, because the spindle head, lathe bed and base console become one unit be screwed.
