    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： 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： In a chuck for axially clamping two machine parts which are releasable from each other, on the first machine part (1) are provided a hollow centring attachment (3), a contact face (6) surrounding the attachment, and an annular groove (8) formed on the inside of the attachment (3) and comprising a groove flank (9) tapering conically towards the free end of the attachment. The second machine part (2) comprises a holding bore (4) which is adapted to the attachment (3) and which is surrounded by an end face (7) against which the contact face (6) can be pressed. In the second machine part are provided several clamping jaws (10) which are each supported by a first end (10a) against a groove flank (12) in the second machine part (2). Arranged radially within the clamping jaws (10) and axially movably is a clamping sleeve (15) which comprises in the region of each end (10a, 10b) of the clamping jaws ( 10) a clamping cone (17, 18) by means of which the clamping jaws (10) are movable radially outwards parallel to themselves and their ends (10a, 10b) can be pressed against the associated groove flanks (9, 12). The clamping jaws (10) comprise at both their ends (10a10b) clamping surfaces (11, 14) whose angular position relative to the central axis (A) is adapted to the groove flanks (9, 12), so that during the whole clamping process there is surface contact between the clamping surfaces (b 11,14) and the groove flanks (9, 12).

    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.

    摘要翻译： 为了将设置有圆柱形或截头圆锥形柄的工具连接到机器主轴的一端处的旋转机器主轴上，提供了用于柄的互补的接收开口。 柄部包含同轴孔和沿圆周方向分布的多个槽，并且径向延伸到孔中，该孔将接收孔内的柄分成段。 在槽的区域中，在离心力的影响下，柄部比围绕柄部的心轴的区域更宽。 因此，即使在10,000转/分的非常高的旋转速度下，工具的径向引导也不会损失。 以上。 工具的环形套环上的支撑肩可防止由于夹紧装置的轴向应力引起的柄的轴向移动，并提高了工具主轴连接的刚性。 孔延伸穿过环形环。 优选地，环形套环的外径大于按照标准。 心轴的端面，旨在抵靠在支撑肩上，径向向内设有环形凹槽，并以最大可能的直径支撑工具。 此外，可以在工具和主轴之间提供形状接合联接。

    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.

On the mutually facing ends of the drive shaft and the driven shaft there are provided coupling parts which can couple without relative rotation therebetween. The driven shaft is provided on the input side with a support pin freely projecting beyond the associated coupling part. The drive shaft is provided in the region of the attachment flange with a coaxial support bore, into which is received the support pin of the tool head.
