Problems solved by technology

In the first alternative, although a precise axial positioning of the screw-in tool inside the receptacle is achieved by the plane of the radial flange, the centering effect by the cylindrical contact surface is limited
Although an improved centering effect can be achieved by the conical contact surface, the outer wall of the tool holder can, however, be deformed outwards due to the wedging action of the conical contact surface, which can have a negative effect on the axial orientation

Embodiment Construction

[0028] exist figure 1 and 2 The figure shows a tool assembly with a screw-in tool 1 and an associated tool receptacle 2 in longitudinal section and in perspective view. The screw-in tool 1 has a tool head 3 designed here as a ball-nose milling cutter and a conical, rearwardly tapering tool shank 4 with an external thread 5 . Provided between the tool head 3 and the external thread 5 is a first support region with a conical first contact surface 6 for bearing against a corresponding conical surface on the front side of the tool receptacle 2 . and a second conical contact surface 8 for abutting against a second conical bearing surface 9 inside the tool receiving device. This results in a double-cone structure at the transition between tool head 3 and external thread 5 , which double-cone structure serves for improved centering and increased support. A second support region 11 is provided on the free rear end 10 of the tool shank 4 .

Abstract

The invention relates to a screw-in tool (1) and a tool holder (2) for such a screw-in tool. A screw-in tool (1) comprising a tool head (3) and a tool shank (4) with an external thread (5) and a support area arranged between the tool head (3) and the external thread (5) . According to the invention, the support region is formed by two conical contact surfaces (6, 8) with different cone angles.

Description

technical field [0001] The invention relates to a screw-in tool / screw drive tool (Einschraubwerkzeug). The invention also relates to a tool receptacle for such a screw-in tool and a tool assembly with a screw-in tool and a tool receptacle. Background technique [0002] WO 2006 / 033617 A1 discloses a screw-in tool comprising a tool head and a tool shank with an external thread and a first support region arranged between the tool head and the external thread. In this known screw-in tool, the first support region is designed either as a radial collar with a planar and cylindrical inner contact surface or as a conical contact surface. In the first alternative, although a precise axial positioning of the screw-in tool within the receptacle is achieved by the plane of the radial flange, the centering effect by the cylindrical contact surface is limited. Although an improved centering effect can be achieved by the conical contact surface, the outer wall of the tool holder can be d...
