发明名称 CLAMPING DEVICE FOR FIXING A TOOL IN A TOOL HOLDER
摘要 In a clamping device for fixing a tool (1) in a holder (2), a hollow centring extension (3) and a bearing face (4) surrounding this centring extension (3) are provided on the tool (1). A tool receptacle (7) provided in the holder (2) has a location bore (8) adapted to the centring extension (3) and an end face (9) which surrounds this location bore (8) and against which the bearing face can be pressed by means of a clamping arrangement. The clamping arrangement comprises a clamping sleeve (10) movable coaxially to the central axis (A) and a clamping ring (11) displaceable in the opposite direction to the clamping sleeve (10). Both the clamping sleeve (10) and the clamping ring (11) are provided with clamping tapers (12, 13) facing one another. The clamping ring (11) can be axially displaced on the clamping sleeve (10) by means of a clamping nut (20) which can be screwed to the clamping sleeve (10). Several clamping claws (14) concentrically surround the clamping sleeve (10) and the clamping ring (11) and are each supported with an end (14a, 14b) on their clamping tapers (12, 13). At their two ends (14a, 14b), the clamping claws (14) have clamping surfaces (15, 16) which interact with a taper surface (17) of the tool receptacle (7) as well as with a taper surface (5) in the centring extension (3), which taper surface (5) is directed in the opposite direction to the taper surface (17). …<IMAGE>…
