Abstract

The invention relates to a tool receptacle 1 comprising a receiving body 3 , which has a receiving opening 5 for a tool shaft 6 of a tool and a first fluid supply structure 22, 33 and 35 for supplying fluid to the tool, said fluid supply structure extending through the receiving body 3 . In order to allow a diversified supply of working fluids to the tool, a second fluid supply structure 23, 34 and 41 , which is not connected with the first fluid supply structure 22, 33 and 35 , extends through the receiving body 3 , hereby allowing a fluid supply to the tool which is separate from the first fluid supply structure 22, 33 and 35.

First claim

The invention claimed is:

1. A tool receptacle ( 1 ) comprising a receiving body ( 3 ), which has a receiving opening ( 5 ) for connection to a tool shaft ( 6 ) of a tool and a first fluid supply structure ( 22 , 33 , 35 ) for supplying fluid to the tool, the first fluid supply structure ( 22 , 33 , 35 ) extending through the receiving body ( 3 ), and further comprising a second fluid supply structure ( 23 , 34 , 41 ) which is not connected with the first fluid supply structure ( 22 , 33 , 35 ), wherein the second fluid supply structure ( 23 , 34 , 41 ) extends through the receiving body ( 3 ) and provides, a fluid supply to the tool which is separate from the first fluid supply structure ( 22 , 33 , 35 ), wherein the first fluid supply structure ( 22 , 33 , 35 ) is formed by a first through hole ( 22 ) positioned in a connecting piece ( 17 ) arranged in the receiving body ( 3 ), a second through hole ( 33 ) is positioned in a transfer element ( 9 ) arranged in the receiving body ( 3 ), and a connecting tube ( 35 ) is arranged in the receiving body ( 3 ) for connecting the first and second through holes ( 22 , 33 ).

2. The tool receptacle of claim 1 , wherein the second fluid supply structure ( 23 , 34 , 40 ) is formed in the connecting piece ( 17 ) and includes at least one thoroughfare channel ( 23 ) which is separated from the first through hole ( 22 ), the transfer element ( 9 ) includes at least one further thoroughfare channel ( 34 ) which is separated from the second through hole ( 33 ), and a connecting passage ( 41 ) arranged in the receiving body ( 3 ) for connecting the thoroughfare channels ( 23 , 34 ).

3. The tool receptacle of claim 2 , wherein the transfer element ( 9 ) is connected with the connecting piece ( 17 ) by means of a sealing sleeve ( 40 ) arranged inside a through hole ( 8 ) of the receiving body ( 3 ).

4. The tool receptacle of claim 3 , wherein the sealing sleeve ( 40 ) is arranged in concentric fashion about the connecting tube ( 35 ) and the connecting passage ( 41 ) is restricted between an inner wall of the sealing sleeve ( 40 ) and an outer wall of the connecting tube ( 35 ).

5. The tool receptacle of claim 3 , wherein the sealing sleeve ( 40 ) and the connecting piece ( 17 ) are connected with one another in overlapping fashion, thereby ensuring a sealed connection between the transfer element ( 9 ) and the connecting piece ( 17 ), even when the connecting piece ( 17 ) is axially adjusted.

6. The tool receptacle of claim 1 , wherein the ends of the connecting tube ( 35 ) are radially sealed and arranged in the first through hole ( 22 ) of the connecting piece ( 117 ) and in the second through hole ( 33 ) of the transfer element ( 9 ).

7. The tool receptacle of claim 1 , wherein the second fluid supply structure ( 23 , 34 , 41 ) is arranged in a distribution space ( 26 ) formed between the tool shaft ( 6 ) and the receiving opening ( 5 ), or opens into fluid channels ( 28 , 29 , 48 ) arranged in a frontal tensioned area ( 7 ) of the receiving body ( 3 ).

8. The tool receptacle of claim 7 wherein the fluid channels ( 28 , 29 , 48 ) are formed by cross holes and longitudinal holes ( 28 , 29 ) in the frontal tensioned area of the receiving body ( 3 ), or by longitudinal slots ( 48 ) on the inner side of the receiving opening ( 5 ).

9. The tool receptacle of claim 1 , wherein a sealing component ( 24 ) for sealing the tool shaft ( 6 ) is arranged at the end of the connecting piece ( 17 ) facing the tool shaft ( 6 ).

10. The tool receptacle of claim 1 , wherein an end of the connecting piece ( 17 ) facing the tool shaft ( 6 ) includes a divider element ( 51 ) arranged for distributing fluids supplied via the first fluid supply structure ( 22 , 33 , 35 ) and the second fluid supply structure ( 23 , 34 , 41 ).

11. The tool receptacle of claim 10 , wherein the divider element ( 51 ) has a frontal contact part ( 52 ) and a rear spring element ( 53 ).

12. The tool receptacle of claim 10 , wherein the divider element ( 51 ) has a central passageway ( 56 ) and a depression ( 55 ) in a frontal contract surface ( 54 ).

13. The tool receptacle of claim 10 , wherein the divider element ( 51 ) has a central passageway ( 56 ) and passages ( 57 ) that are connected with the passage channels ( 23 ) of the connecting piece ( 17 ).

14. The tool receptacle of claim 10 , wherein the divider element ( 51 ) has a first passage channel ( 58 ) extending from the inside to the outside of the tool receptacle, and a second passage channel ( 59 ) extending from the outside to the inside of the tool receptacle.

15. The tool receptacle of claim 1 , wherein the tool includes a tool shaft ( 6 ) inserted into a tool receptacle, wherein the tool shaft ( 6 ) includes at least one fluid channel ( 60 ) with at least one inlet port ( 63 ) arranged as a shell surface ( 62 ) of the tool shaft ( 6 ).

16. The tool of claim 15 , wherein a second fluid channel ( 61 ) of the tool shaft ( 6 ) includes at least one inlet port ( 64 ) located at a rear surface ( 65 ) of the tool shaft ( 6 ).

17. The tool receptacle of claim 1 , further comprising a central cooling hole ( 25 ) extending through the tool shaft ( 60 ) and multiple cooling channels ( 49 ) located within the tool shaft ( 6 ) and extending in helical fashion about the central cooling hole ( 25 ).

18. The tool receptacle of claim 17 , wherein the connecting piece ( 17 ) includes a depression ( 50 ) facilitating guidance of fluid supplied through the thoroughfare channel ( 23 ) to the multiple cooling channels ( 49 ).
