Abstract
A tool holder with a main part, a deformable receiving portion for clamping a tool, and at least one blocking element which is designed to engage into a corresponding counter element on the tool in order to prevent the tool from moving axially out of the tool holder. The at least one blocking element is integrally formed with the receiving portion. A clamping system having such a tool holder and a method for producing a receiving portion for such a tool holder are also described.
Claims20
A tool holder comprising:
- a main part;
- a deformable receiving portion for clamping a tool, the deformable receiving portion having a back region relative to a receiving opening in the main part, the back region extending to an end of the deformable receiving portion and having a larger inner diameter compared to an inner diameter of a front region of the deformable receiving portion;
- and
- at least one blocking element formed integrally with the deformable receiving portion, the at least one blocking element disposed in the back region as a projection extending along an interior surface of the back region;
- wherein the at least one blocking element axially extends over a partial inner circumference of the back region of the deformable receiving portion such that the at least one blocking element does not extend along an entire interior surface of the back region from a first end to a second end of the back region, the at least one blocking element configured and arranged for engaging with a corresponding counter element disposed on a shank of the tool to form a connection between the tool and the tool holder thereby preventing axial slippage of the tool from the deformable receiving portion, wherein interior surfaces of the back region radially adjacent the at least one blocking element do not contact exterior surfaces of the tool when the tool is engaged within the tool holder.
