Description

Die bisherige Lagerung der Spindeln bei Horizontaiboh r- und Fräswerken ist für die vielseitige Verwendung dieser Maschinen nicht geeignet.The previous storage of the spindles in horizontal drilling and milling machines is not suitable for the versatile use of these machines.

Die Bohrspindel, die zum Feinausbohren benutzt wird, ist in einer Hohlwelle gelagert, -die ihrerseits in dem Getriebekasten gelagert ist. Die Laufgenauigkeit der Bohrspindel isst also von der der Hohlwelle abhängig. .The drill spindle that is used for fine boring is in one Hollow shaft stored -which in turn is stored in the gear box. The running accuracy the drilling spindle eats depending on that of the hollow shaft. .

Die Hohlwelle, auf der die Planscheibe angebracht ist und die zum Teil zum Fräsen mit Messerköpfen verwendet wird, ist verhältnismäßig großen Beanspruchungen ausgesetzt. Dadurch leidet die Lagerung sehr, und es ist nach kurzer Zeit nicht mehr möglich, mit der Bohrspindel, da diese ja, durch die Hohlwelle beeinflußt wird; genaue Bohrungen auszuführen. Man verwendet daher die Horizon;talbohr- und Fräswerke nur zum Fräsen mit geringer Leistung.The hollow shaft on which the faceplate is attached and which is used for Part used for milling with cutter heads is relatively heavy loads exposed. As a result, the storage suffers a lot, and it is not after a short time more possible with the drilling spindle, since this is influenced by the hollow shaft; to carry out precise bores. The Horizon; valley boring and milling machines are therefore used only for milling with low power.

Die Erfindung sieht nun- eine Spindellagerung vor, bei der die Bohrspindel unabhängig von der Hohlwelle in einem in die Hohlwelle hineingezogenen Arm gelagert wird'. Die Hofilwelde ist in ihrem vorderen Teil in dem Spindelkasten und in ihrem hinteren Teil auf dem in die Hohlwelle hineingezogenen Arm gelagert. Durch diese Erfindung wird erreicht, daß man einerseits Feinstbohrungen und andererseits schwere Fräsarbeiten ausführen. kann, ohne daß eine Lagerung die andere beeinflußt.The invention now provides a spindle bearing in which the drilling spindle stored independently of the hollow shaft in an arm drawn into the hollow shaft will'. The Hofilwelde is in its front part in the headstock and in its rear part mounted on the arm drawn into the hollow shaft. Through this Invention is achieved that on the one hand fine bores and on the other hand heavy Perform milling work. can without one bearing affecting the other.

Es ist also möglich, bei dieser Spindellagerüng das Bohrwerk ails Langfräsmaschine für schwerste Schnitte und auch trotzdem zum Feinbohren zu verwenden. Die Zeichnung zeigt einen Schnitt durch die Frässpindellagerung. Der Arm a, der an der hinteren Wand b des Spind'elkastens angebracht ist, ragt in die Hohlwelle c hinein und' nimmt in seinem vordersten Ende beispielsweise ein Wälzlager d auf, in welchem die Bohrspindel e gelagert ist. Diese Spindel wird an der Hinterwand b des Spindelkastens noch einmal gelagert. An der stärksten, Stelle f des ,Armes, a ist die Hohlwelle c gelagert, die andererseits am vorderen Ende g in der Vorderwand h des Getriebekastens gelagert ist.It is therefore possible to use the boring mill with this spindle bearing Long milling machine for the heaviest cuts and can still be used for fine boring. The drawing shows a section through the milling spindle bearing. The arm a, the is attached to the rear wall b of the Spind'elkastens, protrudes into the hollow shaft c in and 'takes a roller bearing d in its foremost end, for example, in which the drilling spindle e is mounted. This spindle is on the back wall b of the headstock stored again. At the strongest point of the arm a, the hollow shaft c is supported, the other hand at the front end g in the front wall h of the gear box is stored.
