Abstract

A tool receptacle for a screw-in tool having a main body, which has a receiving region including at least one conical contact surface for supporting a corresponding conical support surface of the screw-in tool. For thread-protection and for tightening with high concentricity and low production outlay, an insert is disposed in the main body, the insert is movable transversely with respect to the longitudinal axis of the main body and is rotationally-fixed with respect to the main body and has a mating thread for a thread on the screw-in tool.

First claim

The invention claimed is:

1. A tool receptacle for a screw-in tool that is screwed into an insert, said tool receptacle comprising:
a main body including a receiving region that includes at least one conical support surface for contact with a corresponding conical support surface of the screw-in tool; and
an insert movable transversely to a longitudinal axis of the main body and secured against rotation in relation to the main body, said insert being arranged in the main body, and said insert including a matching thread for engaging a corresponding thread on the screw-in tool,
wherein at least one damping element is arranged between the insert and the main body for damping transverse movement of the insert inside the main body and for damping vibrations between the insert and the main body.

2. The tool receptacle according to claim 1 , wherein the insert is connected to the tool receptacle via a form-fitting connection.

3. The tool receptacle according to claim 1 , wherein a first conical support surface is arranged on a front end face of the main body for a first of the conical support surfaces of the screw-in tool, and a second conical support surface is arranged in an interior of the main body for a second of the conical support surfaces of the screw-in tool.

4. The tool receptacle according to claim 1 , wherein the matching thread on the insert is constructed as an internal thread for receiving the corresponding thread, which is constructed as an external thread, on the screw-in tool.

5. The tool receptacle according to claim 4 , wherein the matching thread on the insert is constructed as a trapezoidal thread, a round thread, or a buttress thread.

6. A tool arrangement comprising:
a tool receptacle according to claim 1 ; and
a screw-in tool that includes a plurality of conical support surfaces for contacting the conical support surfaces of the tool receptacle.

7. The tool arrangement according to claim 6 ,
wherein a first conical support surface of the tool receptacle is at a front end face of the main body, and a second conical support surface of the tool receptacle is in an interior of the main body,
a first of the plurality of conical support surfaces of the screw-in tool contacts with the first conical support surface of the main body, and a second of the plurality of conical contact surfaces of the screw-in tool contacts with the second conical support surface in the interior of the main body, and
the first of the plurality of conical support surfaces of the screw-in tool has a cone angle of 140° to 179°, and the second of the plurality of conical support surfaces of the screw-in tool has a cone angle of 1° to 40°.

8. The tool receptacle according to claim 1 , wherein the insert protrudes from a rear end face of the main body, and includes, on a rear end, an annular shoulder for contacting the rear end face of the main body.

9. The tool receptacle according to claim 1 , wherein the insert is arranged completely inside the main body, and is fixedly connected to the main body in a region opposite the thread.

10. The tool receptacle according to claim 1 , wherein the insert is constructed as a sleeve arranged inside the main body so as to be movable with a predetermined play transverse to the longitudinal axis of the main body.

11. The tool receptacle according to claim 1 , wherein a cone angle of a first conical support surface of the receiving region of the main body is about 170°.

12. The tool receptacle according to claim 11 , wherein a cone angle of a second conical support surface of the receiving region of the main body is about 10°.

13. The tool receptacle according to claim 1 , wherein a cone angle of a second conical support surface of the receiving region of the main body is about 10°.

14. A tool receptacle for a screw-in tool that is screwed into an insert, said tool receptacle comprising:
a main body including a receiving region that includes at least one conical support surface for contact with a corresponding conical support surface of the screw-in tool; and
an insert movable transversely to a longitudinal axis of the main body and secured against rotation in relation to the main body, said insert being arranged in the main body, and said insert including a matching thread for engaging a corresponding thread on the screw-in tool,
wherein the insert is connected to the tool receptacle via a form-fitting connection, and
wherein the insert has an external profile for form-fitting engagement with a corresponding internal profile in the main body.

15. The tool receptacle according to claim 14 , wherein the external profile of the insert is constructed as an external hexagon and is arranged with a slight radial play in the internal profile constructed as an internal hexagon in the main body.
