Abstract

This selective cooling device not only provides a simple and effective solution to cooling and lubricating problems on machine tools, but also permits additional means of machining workpieces. The object of the invention is to carry out, for example, axial and radial machining operations on turned parts. This object is achieved in that the tool holder drives a tool by a cooling medium under pressure. Thus, eccentric bores, internal and external polygons, positive and negative grooves, threads, etc, can be made, for example, on turned parts. Axial and radial movements can thus be carried out in a superimposed manner by this solution.

Description

Diese selektive Kühlvorrichtung dient nicht nur zur einfachen und rationellen Lösung von Kühl- und Schmierproblemen an Werkzeugmaschinen, Probleme wie durch DE-P 36 17 540.4 sowie durch DE-P 36 31 763.2-14 bereits bekannt und gelöst, sondern erlaubt zu­ sätzliche Bearbeitungsmöglichkeiten von Werkstücken.This selective cooling device is not only used for simple and rational solution of cooling and Lubrication problems on machine tools, problems like by DE-P 36 17 540.4 and by DE-P 36 31 763.2-14 already known and solved, but allowed to additional processing options for workpieces.

Der Erfindung liegt die Aufgabe zugrunde, ein in einem Werkzeughalter (1) angebrachtes Werkzeug (7) in vor­ zugsweise rotative Bewegung zu versetzen.The invention has for its object to set a tool ( 7 ) attached in a tool holder ( 1 ) in preferably rotational movement.

Dies wird durch unter Druck stehendes Kühlmedium aus aus der Hochdruckpumpe für Kühlmedium (12) ermöglicht. This is made possible by pressurized cooling medium from the high pressure pump for cooling medium ( 12 ).

Die Kühlmediumspumpe (11) beaufschlagt über die Kühl­ mediumsweiche (8) vorzugsweise ein innen- oder außen­ gekühltes Werkzeug (siehe DE-P 36 31 763.2-14).The coolant pump ( 11 ) acts on the coolant switch ( 8 ) preferably an internally or externally cooled tool (see DE-P 36 31 763.2-14).

Durch Umrüstung des Werkzeughalters (1) auf einen mit Treibrad (3), Antriebswelle (4), Lagerung (5), Spannzange (6) und Werkzeug (7) ausgestatteten Werk­ zeughaltereinsatz (2) wird das Werkzeug (7) durch die Hochdruckpumpe für Kühlmedium (12) aus dem Kühlmediumsbehälter (15) in Bewegung versetzt (Fig. 17).By conversion of the tool holder (1) to a flask equipped with drive wheel (3), drive shaft (4), storage (5), the collet (6) and tool (7) Tool holder insert (2), the tool (7) by the high pressure pump Cooling medium ( 12 ) from the cooling medium container ( 15 ) set in motion ( Fig. 17).

Der Durchfluß der Stellkugel für Kühlmedium (10) wird über den Druckminderer (9) eingestellt.The flow of the control ball for cooling medium ( 10 ) is set via the pressure reducer ( 9 ).

Der für das Werkzeug (7) benötigte Druck am Treib­ rad (3) wird durch das Leistungsstellglied (14) der Hochdruckpumpe für Kühlmedium (12) eingestellt (Fig. 1).The pressure on the driving wheel ( 3 ) required for the tool ( 7 ) is set by the power actuator ( 14 ) of the high-pressure pump for cooling medium ( 12 ) ( FIG. 1).

Das Rückschlagventil (13) der Kühlmediumspumpe (11) verhindert den Druckabfall im Kühlmediumszulauf (20) über die Kühlmediumspumpe (11) (Fig. 1). The check valve ( 13 ) of the coolant pump ( 11 ) prevents the pressure drop in the coolant supply ( 20 ) via the coolant pump ( 11 ) ( Fig. 1).

Die Werkzeugkennung (16), der Schalter (17) und die Leistungsversorgung (18) schalten durch die Umrüstung der Werkzeugmaschine die Hochdruckpumpe für Kühl­ medium (12) in aktiven Zustand (Fig. 1).The tool identifier ( 16 ), the switch ( 17 ) and the power supply ( 18 ) switch through the conversion of the machine tool, the high pressure pump for cooling medium ( 12 ) in the active state ( Fig. 1).

Die Bewegungsrichtung des Treibrades (3) bzw. des Werkzeuges (7) kann durch Verdrehen des Werkzeughal­ tereinsatzes (2) im Werkzeughalter (1) geändert werden. Dies kann vorzugsweise durch Vertauschen des Kühlmittelzulaufs (20) und des Kühlmittel­ rücklaufs (19) erfolgen (Fig. 2, 3).The direction of movement of the drive wheel ( 3 ) or the tool ( 7 ) can be changed by turning the tool holder insert ( 2 ) in the tool holder ( 1 ). This can preferably be done by interchanging the coolant inlet ( 20 ) and the coolant return ( 19 ) ( Fig. 2, 3).
