Abstract

The invention relates to a tooth-edge cutting machine for rotationally symmetric workpieces (1), comprising a work spindle and two tool spindles (3) arranged symmetrically to the workpiece axis for accommodating one tool (2) each, drives being provided for rotating the workpiece (1) and the tools (2). In order to manage with the least possible number of degrees of freedom, provision is made for each tool (2) to be adjustable parallel to and transversely to the workpiece axis and also at an angle in two planes perpendicular to one another, and for the drives (4) for rotating the tools to be synchronised with the drive for rotating the workpiece in accordance with tooth form and pitch. <IMAGE>

Description

Die Erfindung betrifft eine Zahnkantenbearbeitungsmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a tooth edge processing machine according to the preamble of claim 1.

Bekannte Zahnkantenbearbeitungsmaschinen zur Komplettbear­ beitung von rotationssymmetrischen Werkstücken benötigen dreizehn Frei­ heitsgrade, u.a. eine Tangentialverstellung der Werkzeugspindeln. Dies bedeutet einen erheblichen Aufwand.Known tooth edge processing machines for complete machining Machining rotationally symmetrical workpieces require thirteen free degrees, among others a tangential adjustment of the tool spindles. This means a considerable effort.

Aufgabe der Erfindung ist es, eine Zahnkantenbearbeitungsma­ schine nach dem Oberbegriff des Anspruchs 1 zu schaffen, die mit einer verringerten Zahl an Freiheitsgraden auskommt und daher konstruktiv einfacher ist.The object of the invention is to provide a tooth edge machining create according to the preamble of claim 1, with a reduced number of degrees of freedom and therefore constructive is easier.

Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des Anspruchs 1 gelöst.This task is performed according to the characteristic part of the Claim 1 solved.

Hierdurch wird erreicht, daß man mit elf Freiheitsgraden für zwei Werkzeuge und das Werkstück auskommt, auf die bisher vorgesehene zusätzliche Tangentialverstellung wird verzichtet.This ensures that one with eleven degrees of freedom for two tools and the workpiece gets along on the previously provided additional tangential adjustment is dispensed with.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further refinements of the invention are as follows Description and the dependent claims.

Die Erfindung wird nachstehend anhand des in der beigefügten Abbildung dargestellten Grundmodells für die Zahnkantenbearbeitungsma­ schine näher erläutert. The invention is illustrated below in the attached Figure shown basic model for tooth edge machining machine explained in more detail.  

Die Zahnkantenbearbeitungsmaschine umfaßt elf Freiheitsgrade, und zwar Werkstückrotation C(das zu bearbeitende Werkstück 1 wird mittels einer nicht dargestellten Werkstückspindel an einem Werkstück­ spindelstock aufgespannt und ist mittels eines CNC-gesteuerten Antriebs drehbar);
Werkzeugrotation T 1 und T 2 (zwei spiegelsymmetrisch zum Werkstück 1 angeordnete Werkzeuge 2, die von Werkzeugspindeln 3 aufge­ nommen werden und über CNC-gesteuerte Antriebe 4 antreibbar sind);
Neigungswinkel A 1 bzw. A 2 für die jeweilige Achse 5 des je­ weiligen Werkzeugs 2;
Schwenkwinkel B 1 bzw. B 2 für die jeweilige Achse 5 des je­ weiligen Werkzeugs 2;
(die Freiheitsgrade Neigungs- und Schwenkwinkel A 1, B 1 und A 2, B 2 können durch jeweils einen kugelgelenkartigen Schwenkkopf oder getrennt voneinander CNC-gesteuert oder manuell einstellbar sein) ;
Vorschub Z 1 bzw. Z 2 (realisiert durch entsprechende, parallel zur Werkstückachse verstellbare Längsschlitten 6, die CNC- oder manuell gesteuert sind und die Einrichtungen zur Realisierung der vorstehend aufgeführten Freiheitsgrade für jeweils ein Werkzeug 2 tragen);
Zustellung X 1 bzw. X 2 (realisiert durch entsprechende jeweils einen Längsschlitten 6 aufnehmende Querschlitten 7, die CNC- oder ma­ nuell gesteuert und senkrecht zur Werkstückachse verstellbar angeordnet sind).The tooth edge processing machine comprises eleven degrees of freedom, namely workpiece rotation C (the workpiece 1 to be machined is clamped on a workpiece headstock by means of a workpiece spindle, not shown, and can be rotated by means of a CNC-controlled drive);
Tool rotation T 1 and T 2 (two tools 2 arranged mirror-symmetrically to the workpiece 1 , which are taken up by tool spindles 3 and can be driven via CNC-controlled drives 4 );
Inclination angle A 1 or A 2 for the respective axis 5 of the respective tool 2 ;
Swivel angle B 1 or B 2 for the respective axis 5 of the respective tool 2 ;
(The degrees of freedom inclination and swiveling angles A 1 , B 1 and A 2 , B 2 can be CNC-controlled or manually adjustable by means of a ball joint-like swivel head or separately from one another);
Feed Z 1 or Z 2 (realized by means of corresponding longitudinal slides 6 which can be adjusted parallel to the workpiece axis and which are controlled by CNC or manually and which carry the devices for realizing the above-mentioned degrees of freedom for one tool 2 each);
Infeed X 1 or X 2 (realized by corresponding cross slides 7 each accommodating a longitudinal slide 6 , which are controlled by CNC or manually and are adjustable perpendicular to the workpiece axis).

Die Werkzeugrotation ist mit der Werkstückrotation entspre­ chend Zahnform und -teilung synchronisiert, während die beiden Werk­ zeugspindeln in ihren Freiheitsgraden unabhängig voneinander zur Erzie­ lung eines vergrößerten Arbeitsbereichs einstellbar sein können.The tool rotation corresponds to the workpiece rotation Tooth shape and pitch synchronized while the two work Free spindles in their degrees of freedom for education development of an enlarged work area can be adjustable.

Die Querschlitten 7 können auf einem gemeinsamen Bettschlit­ ten (nicht dargestellt) angeordnet sein.The cross slide 7 can be arranged on a common bed slide (not shown).

Ferner können Werkzeugwechsler mit entsprechenden Werkzeug­ magazinen vorgesehen sein.Tool changers can also be used with appropriate tools magazines may be provided.
