Abstract

A tool support for fixed or rotating tools embodied with a collet chuck receiver for a collet chuck for clamping a tool shaft from the direction of the tool side. The collet chuck receiver has a tapering bore for receiving a collet chuck and a coaxial screw thread assigned to the bore for receiving a tensioning nut. In place of a collet chuck, a tool clamping insert is inserted with a tapering receiving neck into the tapering receiving bore, wherein the tool clamping insert is clamped in place by fastening means from the direction of the tool side.

Claims

1. A tool support for fixed or rotating tools,

having a collet chuck receiver (4) embodied on tool support means for a collet chuck (6) used for clamping a tool shaft (8) from the direction of the side of the tool, wherein the collet chuck receiver (4) has a tapering bore (5) having a bore axis for receiving a collet chuck (6) and a coaxial screw thread (12), assigned to the bore for receiving a tensioning nut (10),

having a first end face (18) at the tool support means (2), assigned to the tapering bore (5) and extending at right angles to the bore axis (14), and

having fastening means (20) on the tool support means for a tool clamping insert (23), which is inserted by means of a tapering receiving neck (24) into the tapering bore (5) in place of the collet chuck (6), wherein the fastening means are accessible from the direction of the tool side.

2. The tool support in accordance with claim 1, characterized in that it has a tool clamping insert (23), which is inserted by means of a tapering receiving neck (24) into the tapering bore (5) and which is releasably fastened by fastening means (20, 28, 30) on the tool support means (2).

3. The tool support in accordance with claim 2, characterized in that the tool clamping insert (23) has a second end face (25) and that, with the tool clamping insert (23) inserted into the tapering bore (5), the two end faces (18, 25) are kept in contact with each other free of play by the fastening means (20).

4. The tool support in accordance with claim 1, characterized in that fastening means (20) are arranged in the area of the first end face (18).

5. The tool support in accordance with claim 4, characterized in that the fastening means have threaded bores (20), which are arranged axis-parallel in respect to the tapering bore (5) in the first end face (18).

6. The tool support in accordance with claim 1, characterized in that at least one transverse bore (21) extending transversely in respect to the axis (14) of the tapering bore (5) is provided in the tool support means, by means of which a clamping device (33) on a tool clamping insert (23) inserted into the collet chuck receiver is accessible from the outside.

7. The tool support in accordance with claim 1, characterized by at least one tool clamping device (33), which extends transversely to the axis of the receiving neck (24) and is arranged on the tool clamping insert (23) so it can be operated from the outside.

8. The tool support in accordance with claim 1, characterized in that the screw thread of the collet chuck receiver is an internal screw thread (12).

9. The tool support in accordance with claim 8, characterized in that the tool clamping insert (23), which has been inserted into the tapering bore (5), is radially set back in the area (26) of the internal screw thread (12) in respect to the tool support means.

10. The tool support in accordance with claim 6, characterized in that the tool clamping device has a tensioning screw (33), which is screwed into a corresponding threaded bore (34) of the tool clamping insert (23) and through which the transverse bore (21) is accessible.

11. The tool support in accordance with claim 10, characterized in that the tensioning screw (33b) has a tapering clamping neck (43).

12. The tool support in accordance with claim 2, characterized in that the tool clamping insert (23c) has an external screw thread (54), on which a tensioning nut (53) of a clamping device on the tool clamping insert (23c) is screwed.

13. The tool support in accordance with claim 3, characterized in that the tool clamping insert is designed for receiving a quick-action change insert (45), which is inserted with a shaft (46) into the clamping insert (23c) and which is releasably connected with the clamping insert.

14. The tool support in accordance with claim 13, characterized in that the quick-action change insert (45) supports a split ring (51), which is acted upon by a tensioning nut (53) screwed onto a corresponding external screw thread (54) of the clamping insert (23c).

15. The tool support in accordance with claim 1, characterized in that it is designed as a tool holder.

16. The tool support in accordance with claim 1, characterized in that the tool support means (2) have at least one recess (22) on their circumference for a hooked wrench to be placed against, and that stationary seating means (62) are arranged in the vicinity of the tool support means, on which a substantially L-shaped double-hooked wrench (57) is pivotably seated, which has two legs (58), each of which supports a blocking element (59) pointing inward, and that when a blocking element (59) of a leg (58) engages a recess (22), the blocking element (59) of the other leg (58) is maintained out of contact with a recess.

17. A double-hooked wrench for use with a tool support in accordance with claim 16.

18. A tool clamping insert for use with a tool support in accordance with claim 1, having a tapering receiving neck (24), which is inserted into a tapering receiving bore (5) of a collet chuck receiver (4), having a second end face (25) extending at right angles in respect to the longitudinal center axis of the receiving neck, which has means for maintaining the end face (25) in contact with a first end face (18) assigned to the collet chuck receiver (4), and having a tool clamping device, which can be operated from the outside.

19. The tool clamping insert in accordance with claim 18, characterized in that it is arranged for receiving a tool quick-action change insert (45), and that the tool clamping device is a clamping device for the tool quick-action change insert (45).

20. The tool clamping insert in accordance with claim 19, characterized in that the clamping device has a tensioning nut (53) screwed onto a screw thread (54) of the tool clamping insert (23c), and that the tool quick-action change insert (45) supports a ring (51), on which the tensioning nut can be supported.
