摘要： A chuck-claw coupling mechanism includes a coupling member provided in a master jaw, a first resilient member, and an operation unit. The coupling member is movable between a coupling position at which the coupling member is coupled to the claw, and a separation position at which the coupling member is separated from the claw. The first resilient member urges the coupling member toward the coupling position. The operation unit moves the coupling member to the separation position.

摘要： A chuck with a chuck body having a guide opening and an actuating element, and with at least one interchangeable clamp that can be inserted into the guide opening. The clamp has associated therewith a rotary disk with a blocking element that secures the rotary disk against rotation relative to the chuck body during insertion of the clamp into the guide opening. This makes it possible that, upon a rotation of the clamp about the longitudinal axis in the guide opening, a segment can be displaced outward toward the chuck body by the rotation relative to the rotary disk, via which the clamp is detachably secured on the chuck body. A clamp with a clamp body, a pivot body located in the clamp body, and a chucking element is also provided. The clamp has, at the opposite end of the clamping element, a locking unit that carries the pivot body.

摘要： The invention relates to a clamping device (1) for clamping a workpiece and is comprised of a chuck (2) and a collet (3) situated in the chuck (2). A bayonet closure is provided via which the collet (3) can be secured in the chuck (2) or released from it without a tool; the collet (3) can be moved between a clamped position and a release position against a fixed part of the chuck (2). At least one locking element (23) is situated in the fixed part of the chuck (2) that secures the bayonet closure against a release in the clamped position and that releases the bayonet closure for actuation in the release position.

摘要： The jaws of the chuck include a base jaw and a separate, releasable mounting jaw. These two jaw components are connected by at least one shaft which is guided with male-type screw threads in its one end in female-type screw threads of the base jaw. The other end has a lock head which has a projecting lock shoulder, and which lock head can engage in axial direction into a lock retainer in the mounting jaw, when the shaft has been rotated into the position corresponding to the unlocked condition. When the shaft has been rotated into the position which corresponds to the locked condition, it can engage with its lock shoulder in a dovetail formation in axial and positive locking manner. The shaft is further shaped with gear teeth which can operate in the manner of a pinion. In the apparatus there is also provided a control bolt extending transversely to the axis and guided and adapted to be shifted in its longitudinal direction in the base jaw. The control bolt has transversely extending gear-rack type teeth which can meshingly engage with the teeth of the associated shaft. For shifting of a control bolt there are provided control pieces on either side of a base jaw, and these are guided and moved in their longitudinal direction by means of push rods which are axially guided in the chuck base and which can be actuated from the outside of the chuck base against the force of reset springs disposed in the base. Motive power transmission is by wedge-type transmissions.
摘要翻译： 卡盘的夹爪包括一个底座夹爪和一个单独的，可拆卸的安装爪。 这两个钳口部件通过至少一个轴连接，所述至少一个轴在其一端由公型螺纹引导在基座钳口的阴型螺纹中。 另一端具有锁定头，该锁头具有突出的锁定肩部，并且当轴已经旋转到与解锁状态相对应的位置时，锁定头可以在轴向方向上接合到安装爪中的锁定保持器中。 当轴已经旋转到对应于锁定状态的位置时，其可以以轴向和正向锁定方式以燕尾形状与其锁定肩部接合。 轴进一步成形为可以以小齿轮的方式操作的齿轮齿。 在该装置中，还设置有横向于轴线延伸并且被引导并适于在基部钳口中沿其纵向方向移动的控制螺栓。 控制螺栓具有横向延伸的齿条齿，其可与相关轴的齿啮合。 为了移动控制螺栓，在基座夹爪的两侧设置有控制件，并且这些控制件通过在卡盘底座中被轴向引导并且可以从外部致动的推杆在其纵向方向上被引导和移动 的卡盘基部抵抗设置在基座中的复位弹簧的力。 动力传动是楔形传动。

摘要： An apparatus is provided which enables the jaws of a chuck 10 to be removed from and inserted into jaw-ways 12, 13, 14 using a conventional workpiece handler, rather than a sophisticated and highly accurate dedicated jaw handling mechanism. A conventional workpiece handler cannot position a jaw to close tolerances but this problem is overcome by using a guide shoe 17 which can receive a jaw from the workpiece handler in any one of a range of positions and then accurately guide the jaw into one of the jaw-ways 12, 13, or 14.A mechanism 16 is provided for releasing the jaws from the jaw-ways, and for re-locking the jaws in position.

摘要： A chuck-claw guide structure includes a guide-space delimiting part that delimits a guide space in communication with an attachment groove, and a regulation part provided on the guide-space delimiting part. The guide-space delimiting part has a contact surface configured to regulate the claw in contact therewith at a position along the attachment groove in a first direction. The regulation part is configured to regulate the claw at a position along the attachment groove in a second direction different from the first direction.

摘要： A changer device for inserting a clamping head into and/or removing the clamping head from the clamping chuck, wherein the clamping head has a plurality of clamping jaws mutually displaceable in a radial direction and which can be mutually subjected to force by the changer device toward or away from one another in the radial direction.
The changer device has a base and a plurality of adjusting elements which are movably attached to the base and which in each case have at least one engagement portion for the application of force onto the clamping jaws.
The changer device has a drive member which is rotatably movable about a central axis relative to the base. The drive member is coupled by a gear mechanism to the adjusting elements such that by a rotational movement of the drive member the adjusting elements can be jointly moved toward one another or away from one another.
