  • Patent number: 10464141
    Abstract: A collet chuck for clamping a tool shank, comprising a chuck body, a collet and a multi-part clamping nut consisting of a clamping ring and a threaded section rotatably connected to each other via rolling elements, otherwise connected in an interlocking manner, wherein the clamping ring and the collet comprise interlocking coupling elements designed such that the collet can be inserted into the collet housing through the central opening, facing away from the chuck body, of the clamping ring held on the chuck body, while the coupling elements move past each other, and then the coupling elements can be brought into engagement with each other by rotating the clamping ring relative to the collet, so that the clamping ring can transmit the forces applied to it by the threaded section during tightening to the collet via the coupling element and can drive the collet into the chuck body.

  • Patent number: 10245650
    Abstract: A chucking device for a tool includes a tool receiving element; a collet for clamping the tool, the collet being inserted in an opening in the tool receiving element; a clamping nut for axially displacing the collet in relation to the tool receiving element; and a pressure piece which is arranged between the clamping nut and the collet and is rotatably mounted in relation to the clamping nut, by means of which piece the collet can be axially displaced in relation to the tool receiving element by the clamping nut. To permit a tool shank to be securely clamped in and released from the collet, even under extremely high clamping forces, the pressure piece has coupling elements for a torsion-proof connection to corresponding mating elements of the tool receiving element.

  • Patent number: 10165629
    Abstract: The induction coil unit for heating a component which is rotationally symmetrical relative to an axis, includes a plurality of coils arranged about the axis of the tool holder, with pole elements, which are movable radially with respect to the axis, of which pole elements each one consists of includes a stack of pole rods that can be moved relative to one another. A yoke ring connects the pole elements, which, when the coils are excited by alternating current in the tool holder, produce a magnetic flux running in the peripheral direction to inductively heat the tool holder. The pole rods of each pole element can be moved jointly by means of pinion rollers, wherein, however, slide couplings or the like are provided in the drive force transmission path between the individual pole rods so that the pole elements can adapt to different contours of the tool holder.

  • Patent number: 10129933
    Abstract: According to the invention, for shrinking and expanding a tool in the bush part (3) of a tool holder, an induction coil unit (1), in which several polar parts (25) made of a soft magnetic material are radially adjusted in the yoke ring made of a soft magnetic material, is provided. Said polar parts have end faces (29) which are inclined in relation to the axis of rotation (7) of the bush part (3) and can be kept in a linear contact with a conical peripheral surface (31) of the bush part (3) which holds a the tool (11) in a press fit manner. In order to avoid possible local overheating of the bush part (3), the area (39) of the end face (29) parallel to the axis is connected on the output side of the tool to an area (33) of the end face (29) inclined in relation to the axis of rotation (7).

  • Patent number: 10022806
    Abstract: Damping elements for tool chucking systems for damping vibrations and shocks that occur during machining in the case of force-fitting clamping of tools in a tool receptacle or on the tool itself. At least one damping element consisting of a shape memory alloy having a mechanical effect is provided in a tool chucking system or on the tool itself, such that the damping element provided in the chucked state in the force flow of the chucked elements is present in a reversible and hysteresis-dependent state by way of a mechanical force action and the associated crystalline conversion via the pretensioning of said damping element and leads to dissipation of mechanical energy. The mechanical energy to be damped is a cyclical vibration or represents a non-cyclical overload which is transmitted in the form of shocks.

  • Patent number: 9878376
    Abstract: The invention provides a clamping system (1) for a rotary tool (70), for example a milling cutter or drill. The clamping system (1) includes a base element (10), a collet (30) and a clamping nut (50), said clamping nut (50) friction-locking the rotary tool (70) within the base element (10) with the collet (30). In order to avoid a relative rotation of the base element (10) and the collet (30), the clamping system (1) has a form locking anti-twist protection which blocks a rotation of the collet (30) relative to the base element (10).
