    摘要: For the attachment of a tool provided with a cylindrical or frusto-conical shank to a rotating machine spindle at one end of the machine spindle a complementary reception opening for the shank is provided. The shank contains a coaxial bore and a plurality of slots distributed in the circumferential direction and extending through radially to the bore, which divide the shank within the reception opening into segments. In the region of the slots the shank widens out under the influence of centrifugal forces more than does the region of the spindle surrounding the shank. Thus the radial guidance of the tool is not lost even at very high rotation rates of 10,000 r.p.m. and above. A support shoulder on an annular collar of the tool prevents axial reshifting of the shank by reason of the axial stress of a clamping device and improves the rigidity of the tool-spindle connection. The bore extends through the annular collar. The external diameter of the annular collar is preferably made larger than according to standard. The end face of the spindle, intended to abut on the support shoulder, is radially inwardly provided with an annular recess and supports the tool on a maximum possible diameter. In addition a shape-engaging coupling can be provided between tool and spindle.

    摘要: The actuating arrangement for a tool clamping device (1) has a clamping bar (3) which is axially displaceable in a clamping direction in a machine tool spindle (2) under the effect of a spring arrangement (11) and a firsst wedge transmission assembly (9) which is operable between the spindle and the clamping bar, with freely movable balls which bear respectively against three cone surfaces. They are disposed on a clamping sleeve (13) which is axially displaceable on the clamping bar, on a clamping ring (14) connected to the clamping bar (3), and on a support ring (15) which is arranged stationarily with respect to the spindle. The spring arrangement (11) acts by way of a pressure sleeve (12) which is axially displaceable on the clamping bar. Disposed between the pressure sleeve (12) and the clamping sleeve (13) is a second wedge transmission assembly (10) with freely movable balls which respectively bear against two cone surfaces which are inclined in mutually opposite relationship on the mutually facing ends of the two sleeves (12, 13) and successively against two further cone surfaces which are inclined in opposite relationship on the support ring (15). In the release stroke movement in opposite relationship to the clamping direction a piston-cylinder unit (7, 8) initially acts on the clamping sleeve (13) and then also on an annular shoulder (3a) of the clamping bar (FIG. 1).

    摘要: A tool changer comprises a support (7) movable parallel to the axis (A or B) of a tool holder, a pivoting head (8) which pivots on the support (7) about an axis of rotation (D), and two gripper arms (9, 10) arranged on the head (8) substantially radially with respect to the axis of rotation, their free ends each carrying a gripper (11). The free ends of the gripper arms (9, 10) are so inclined relative to the axis of rotation (D) that the two tool axes (W1, W2) of the tools (5, 6) engaged by the grippers (11) and the axis of rotation (D) intersect in a single point (P), and so that the tool axes (W1, W2) of the tools (5, 6) engaged by the grippers (11) diverge from the axis of rotation (D) towards their holding ends (5a, 6a). Each of the tool axes (W1, W2) includes an acute angle (.alpha.) of about 10.degree. to 30.degree. with the axis of rotation (D). The axis of rotation (D) is so arranged in the support (7) that it intersects the axis (A or B) of the tool holder (4) during the change and includes an angle (.alpha.) with this axis which corresponds to the acute angle (.alpha.).

    摘要: A thread spooler includes a plurality of spool units, each of which includes a thread defect sensor of a defect classification device which reacts to defects of the thread to be wound up. A large number of sets of predetermined operational parameters of the spool units and/or the defect classification devices can be recorded by a central input device into a central memory which stores all these data simultaneously. Each of the spool units includes a decentralized memory, into which one of the centrally stored operational parameter sets can be loaded individually for each spool unit by a call-up switch. A central control determines for respective groups of spool units a predetermined sequence, in which the operational parameter sets can be called up by the spool units. The classification device determines the thread defect, preferably individually for each spool unit, and indeed respectively referred onto the last wound gauged length of the thread. The winding device of the spool unit is operated with the maximum possible rpm. The rpm is reduced if a predetermined maximum thread speed is reached.
