摘要： A clamping device includes a first clamping segment which has a first mounting flange and a tubular member extending axially away therefrom. A first bore extends through the first mounting flange and the tubular member. The first mounting flange is configured for attachment to a rotatable spindle of a machine tool. The clamping device includes a draw bar assembly which has an axially extending elongate shaft. The elongate shaft extends through the first bore of the first clamping segment. A biasing unit is mounted on or in the tubular member. A locking member is removably secured to the elongate shaft such that the biasing unit is compressed between the locking member and a portion of the first clamping segment. The biasing member remains compressed when the first clamping segment is separated from the spindle of the machine tool.

摘要： In a clamping device (1) for machine tools (2) that is equipped with a power-operated chuck (5) and an electric drive motor (11) with a changeover function for triggering clamping movements, a motion converter (31) as well as a force accumulator (51) for maintaining the clamping force, which comprises several spring packs (52) supported on an adjustment element (32) of the motion converter (31), the spring packs (52) are each only arranged on one side of the adjustment element (32). In addition, a pressure piece (53) interacting with the adjustment element (32) is firmly connected to several spacer elements (57), each of which carries a stop disc (61) and passes through the spring packs (52) as well as a spacer (66). The spacer elements (57) and the spacers (66) can be adjusted relative to one another and the spacers (66) interact with spacer pins (71) which are guided through the pressure piece (53) and are supported on the wall (24) of the housing (21) opposite to the spring packs (52).Due to this embodiment, the spring packs (52) are always preloaded and do not have any axial play, and the adjustment movements of the pressure piece can thus be registered and evaluated directly. Rather, the spring packs (52) have a defined preload at all times, with the effect that the operating method is improved compared to embodiments of prior art.

摘要： A toolholder and method for use with a cutting insert having a clamping opening, comprising a toolholder body and a clamp pivotably mounted to and contacting the toolholder body and pivotable between a first position in which a protrusion of the clamp is disposed in a position in which it is arranged to be received in the clamping opening in the cutting insert to secure the cutting insert to the toolholder body and a second position in which the protrusion is spaced, relative to the toolholder, upwardly from the first position so that the cutting insert is not secured to the toolholder body by the protrusion. A resilient member is arranged relative to the clamp to urge the clamp to the first position and to resist pivoting of the clamp to the second position. An opening in the clamp may receive a portion of a separate lever.

摘要： Disclosed is a clamping device of a balancing machine for coaxially clamping a toolholder on a spindle rotary about an axis of rotation (3), in which the coupling shank (8) is supported in the receiving socket only on discrete supports (11-15) which are spaced from each other circumferentially and lie in three relatively spaced engagement planes (E1, E2, E3) intersecting the axis of rotation (3). Four rigid discrete supports (11-14) are arranged in pairs in the first (E1) and the second (E2) engagement plane and combine to form a rigid support in a first radial direction. Formed in the third engagement plane (E3) lying between the first and the second engagement plane is a fifth discrete support (15) which effects a supporting function in a second radial direction opposite the first radial direction.

摘要： A power tool chuck includes at least one claw portion movable from a first position spaced apart from a centerline of the chuck toward a second position located closer to the centerline. The power tool chuck also includes a collar configured such that as the collar moves from a third position to a fourth position, the at least one claw portion is forced from the first position toward the second position. The power tool chuck also includes a locking member movable between a fifth position whereat the locking member locks the collar in the third position and a sixth position whereat the locking member does not lock the collar. The power tool chuck also includes a button movable between a seventh position whereat the locking member is forced into the fifth position and an eighth position whereat the locking member is free to move into the sixth position.
