摘要： A device (100) for capturing, centring, gripping and/or securing an object (140) is disclosed. The device comprises a hub (101) and a ring (102) which are concentric and arranged rotatably relative to each other. On the hub there is at least one first control point (111, 111′, 111″), and on the ring there is at least one second control point (112, 112′, 112″), which control points are arranged at different axial levels (151,152). At least one tensioning member (121,122,123) is arranged to interact with the at least one first control point and with the at least one second control point during the rotation, such that the at least one tensioning member is stretched across the air gap (130) in the device. The different axial levels for the at least one first control point and the at least one second control point mean that the at least one tensioning member can freely pass over the at least one first control point during the rotation and can be stretched across the air gap towards the object. Substantially any desired angle of rotation between the hub and the ring can be obtained in this way.

摘要： A machining system includes a tool head having a yoke, a housing pivotally mounted to the yoke and a collet rotatable in the housing. The collet includes a tool head rocker driven by fluid to allow rocking of a tool relative to the collet in a plane normal to the housing pivotal axis in the yoke. The machining system also includes a source of constant liquid pressure and a source of constant gas pressure. The collet has pressure chambers in communication with the sources of constant pressures to bias the rockable collet assembly. The collet/tool axis is arranged to trail in the direction of relative motion when the contour of the work is moving away from the tool head and to lead when the contour of the work is approaching the tool head.

摘要： An assembly includes a quick-release head, a tail piece and a flexible metal rod. The tail piece includes a shaft and a male coupler formed of a head, body, and flute. At least a portion of the male coupler head has a reduced outer dimension relative to an outer dimension of the body. When the male coupler is mounted in a second quick-release head or drill, a clearance space is provided between the reduced outer dimension portion and the second quick-release head or drill. During use, the assembly may undergo bending which results in significant forces applied in particular to the male coupler head. By providing the clearance space, these forces are predominantly shifted to the male coupler body, thereby reducing the likelihood that the male coupler head will shear from the remainder of the male coupler.

摘要： The invention relates to a method for fixing a tool (10, 22, 64), especially a shaft tool, in a clamping chuck (8, 18, 60), whereby the tool (10, 22, 64) is introduced into the clamping chuck (8, 18, 60) and fixed therein (8, 18, 60) upon reaching an axial nominal position. According to the invention, the tool (10, 22, 64) is brought against an abutment (42, 70) and the position of a characteristic element of the tool (10, 22, 64) is measured. The tool (10, 22, 64) is positioned in the axial nominal position by moving the abutment (42, 70) along a positioning section (Z1) calculated from the measurement.
