Abstract
A tool holder is provided comprising a base body for coupling with a drive spindle that can be driven rotatingly, whereon a clamping chuck for clamping a tool is provided, further comprising a damping element arranged between the base body and the clamping chuck, wherein the damping element is made of an elastomeric material or of a shape memory alloy, and wherein the clamping chuck is solely connected to the base body by means of the damping element.
Claims20
A tool receptacle comprising:
- a base body for coupling with a drive spindle that can be driven rotatingly;
- a clamping chuck for clamping a tool;
- a damping element made of an elastic material arranged between said base body and said clamping chuck, wherein said clamping chuck is solely connected to said base body by means of said damping element;
- and
- a centering truss provided at said base body and a centering truss provided at said clamping chuck, both centering trusses being configured for centering said base body and said clamping chuck precisely with respect to each other within a surrounding mold during a molding and vulcanizing of said damping element.
A tool receptacle comprising:
- a base body for coupling with a drive spindle that can be driven rotatingly;
- a clamping chuck for clamping a tool;
- a damping element made of an elastic material or of a shape memory alloy arranged between said base body and said clamping chuck, wherein said clamping chuck is solely connected to said base body by means of said damping element.
A device for producing a base body for coupling a clamping chuck for clamping a tool with a drive spindle that can be driven rotatingly, wherein a damping element made of an elastic material is arranged between said base body and said clamping chuck, said device comprising:
- a mold comprising a recess for receiving said clamping chuck and said base body centered with respect to each other and secured against axial displacement, with a gap remaining between said clamping chuck and said base body;
- at least one feed channel for feeding elastomeric material under pressure into said gap between said clamping chuck and said base body;
- and
- at least one exhaust channel arranged within said mold leading form said gap to the outside.
A method for producing a tool receptacle comprising a base body for coupling with a drive spindle that can be driven rotatingly, and a clamping chuck for clamping a tool, a continuous damping element made of a elastomeric material being arranged between said base body and said clamping chuck, said method comprising the following steps:
- (a) providing a mold having a recess;
- (b) inserting and centering said base body and said clamping chuck within said recess, thereby providing a continuous gap between said base body and a holding section of said clamping chuck;
- (c) axially securing said base body and said clamping chuck within said mold;
- (d) feeding elastomeric material under pressure into said gap between said base body and said holding section of said clamping chuck, until said gap is completely filled, while providing an exhaust through at least one exhaust channel provided within said mold;
- (e) vulcanizing said elastomeric material;
- and
- (f) removing the tool receptacle from said mold.
