In order to improve a tool support for machine tools comprising a base unit, a holding member which is arranged on the base unit and on which two supporting surfaces extending at an acute angle to one another are arranged for supporting a tool holder in a first supporting area and a second supporting area, and a clamping device for acting on a clamping member of the tool holder in a clamping direction extending in such a manner that the tool holder acts upon the supporting surfaces with the first and the second supporting areas, in such a manner that clamping of a tool holder is possible in as simple a way as possible it is suggested that the clamping element be mounted in the holding member for rotation about an axis and bear a wedge surface movable on a path around the axis for acting on the clamping member, and that the wedge surface of the clamping element engage over the clamping member proceeding from an insert position during the rotation of the clamping element in a first direction of rotation and act upon this clamping member so as to displace it increasingly in the clamping direction.
Tool support for machine tools comprising a base unit, a holding member arranged on the base unit, two supporting surfaces extending at an acute angle to one another being arranged on said holding member for supporting a tool holder in a first supporting area and a second supporting area, and a clamping device for acting on a clamping member of the tool holder in a clamping direction extending in such a manner that the tool holder acts upon the supporting surfaces with the first and the second supporting areas, characterized in that the clamping element (132) is mounted in the holding member (22) for rotation about an axis (134) and bears a wedge surface (150) movable on a path around the axis (134) for acting on the clamping member (124), and that the wedge surface (150) of the clamping element (132) engages over the clamping member (124) proceeding from an insert position during the rotation of the clamping element (132) in a first direction of rotation (158) and acts upon said clamping member so as to displace it increasingly in the clamping direction (160).
Tool carrier as defined in any one of the preceding claims, characterized in that the clamping element (132) is rotatable about an axis (134) extending transversely to one of the supporting surfaces (70).
Tool support as defined in any one of the preceding claims, characterized in that the clamping element (132) is rotatably mounted in a bore (138) passing through the holding member (22).
Tool support as defined in any one of the preceding claims, characterized in that the clamping element (132) is movable in such a manner that the wedge surface (150) crosses the insert path (156) of the clamping member (124).
Tool support as defined in any one of the preceding claims, characterized in that in the insert position of the clamping element (132) the wedge surface (150) is arranged outside an insert path (156) of the clamping member (124) described by said member during the insertion of the tool holder (20) into the tool support, and that the wedge surface (150) extends transversely to this insert path (156) with the area acting upon the clamping member (124) following rotation of the clamping element (132) in the first direction (158).
Tool support as defined in any one of the preceding claims, characterized in that the clamping element (132) is arranged such that it is in a position to act on the clamping member (124) introduceable in an entry channel (90) arranged in the holding member (22), said entry channel being recessed in relation to one of the supporting surfaces (70).
Tool support as defined in any one of the preceding claims, characterized in that the holding member (22) allows a straight insert path (156).
Tool support as defined in any one of the preceding claims, characterized in that the clamping element (132) is rotatable through an angle of less than 270° for the clamping of the tool holder (20).
Tool support as defined in any one of the preceding claims, characterized in that the clamping element (132) comprises a clamping link member (142) bearing the wedge surface (150).
Tool support as defined in any one of the preceding claims, characterized in that the supporting surfaces (80, 90) and the clamping element (132) are arranged relative to one another in such a manner that the tool holder (20) is adapted to abut with the first and second supporting areas (100, 110) on the corresponding supporting surfaces (70, 80) due to a movement along a straight insert path (156) and to be brought into the operative area of the clamping element (132) with the clamping member (124).
Tool support as defined in any one of the preceding claims, characterized in that one supporting surface (70, 80) of the holding member (22) has partial surfaces (70a, b;
Tool support as defined in any one of the preceding claims, characterized in that the clamping direction (160) extends parallel to a direction located within the angular area limited by the supporting surfaces (80, 90).
Tool support as defined in any one of the preceding claims, characterized in that the base unit (10) is designed as a support shaft (12) and the holding member as a tool disk (22) of a tool turret.
Tool holder comprising a tool holder housing with two supporting areas extending at an acute angle to one another on said housing, said supporting areas being adapted to abut on two supporting surfaces of a holding member of a tool support, characterized in that the tool holder housing (120) is provided with a clamping member (124).
Tool system comprising a tool holder with a tool holder housing having a first and a second supporting area extending at an acute angle to one another and adapted to abut on corresponding supporting surfaces of a holding member of a tool support, and bearing a clamping member acted on by a clamping device of the tool support during the clamping of the tool holder, characterized in that the tool support is designed in accordance with any one of the preceding claims.
