Problems solved by technology

In addition, known nozzle arrangements include a distribution plate for conveying the medium, which however restricts the working space and has to be considered kinematically
In addition, a cost-intensive handling unit (Handhabungseinheit) for changing the tool is required
Furthermore, another disadvantage is that the known systems are limited to solid tapered shank tool holders (Vollschaftkegel-Werkzeugaufnahme), conversely, there is not enough for accommodating (andocken) media for large cone angle connections (Steilkegelverbindung) allocator space
Another important disadvantage is that only the provided hollow-walled nozzle bodies can be manufactured cost-intensively

Embodiment Construction

[0020] exist figure 1 The tool holder schematically shown in the figure basically consists of a shrink chuck 10 which can be placed on the machine tool spindle (Maschinenspindel) for thermally clamping the rotating tool 12 and for spraying, in particular for cooling, lubrication and Nozzle arrangement 14 for liquid and / or gaseous media sweeps away the working region of tool 12 .

[0021] as best as possible from figure 2 As can be seen in FIG. 2 , the nozzle device 14 comprises an inner media supply 16 in the shrink chuck 10 and a nozzle sleeve 18 for screwing onto the conical chuck body 20 of the shrink chuck. The chuck body 20 has an axial perforation 22 embodied as a stepped bore, which is designed to have smaller dimensions in its front section relative to the shank diameter of the tool 12 , which is in particular configured as a drill or milling cutter, so that By heating the collet body 20 on one side, the tool 12 can be clamped or removed in a clamping manner.

Abstract

The invention relates to a tool holder having a rotationally drivable collet chuck (10) for clamping a rotary tool (12) and a nozzle device (14) for impinging a liquid and / or gaseous medium on the rotary tool (12). According to the invention, the nozzle device (14) comprises a nozzle sleeve (18) that can be fixedly connected to the collet chuck (10) and is able to rotate along with said chuck, and the inner wall (34) of the nozzle sleeve (18) bounds an annular channel (38) for conveying the medium relative to the collet chuck (10).

Description

technical field [0001] The invention relates to a tool holder with a rotatably driven collet for clamping a rotary tool, in particular a drill or milling cutter, and for loading the rotary tool with a liquid and / or gaseous medium nozzle device. Background technique [0002] Known from document EP-A 42 05 91984144 is a machine tool (Werkzeugmaschine) which can be equipped with different tool holders and associated nozzle arrangements, wherein the tool holders and nozzle arrangements associated in pairs are loosely engaged with each other, The tool holder is thus rotatable, while the nozzle arrangement has a non-rotating nozzle body which concentrically surrounds a frustoconical tool holder. In this case, the mutual positioning must be so precise that interference cannot occur. Furthermore, the known nozzle arrangements comprise a distribution plate for conveying the medium, which however restricts the working space and has to be considered kinematically. Furthermore, a cos...
