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 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 workholder for a machine tool or the like having a power assembly and a work gripping assembly that are separable to permit use of a plurality of work gripping assemblies and associated work gripping jaws of a size and shape to accommodate different workpieces. Work gripping assemblies with jaws pre-qualified to different workpieces can be exchanged quickly and automatically, as by use of a robot, when different parts are to be machined, while a single power assembly remains connected to the machine tool.

摘要： A chuck jaw changer is provided for a machine tool such as a numerically controlled lathe (22) for automatically changing the gripping jaws (32) of a quick change chuck (28) on its work spindle (26). The set of gripping jaws of the chuck are replaceably engaged in respective radial guideways (56) in a chuck body (30), with each gripping jaw being slid into and out of one guideway when that guideway is in a preassigned jaw change position on the chuck body. The chuck jaw changer has a rotary, indexing jaw magazine (34) having holder grooves (140) defined therein at constant circumferential spacings for releasably holding additional sets of gripping jaws (32') interchangeable with the jaw set on the chuck body. A jaw transfer mechanism (36) transfers a gripping jaw (32, 32') rectilinearly between that one of the guideways (56) in the chuck body which is in the jaw change position and that one of the holder grooves in the jaw magazine which is positioned in line therewith. For accurate jaw transfer a jaw guide (38) is interposed between chuck body and jaw magazine so as to provide a substantially continuous, rectilinear jaw guide track therebetween.

摘要： A chuck for clamping workpieces or tools in a clamping space with a clamping force (F). The chuck includes at least two chuck jaws movable in translation along one clamping plane (E) in the direction of one center Z of the clamping space and a gear train located at least largely within the chuck for transfer of a driving torque of a drive motor, which can be coupled to the gear train by coupling means of the gear train, to the chuck jaws for movement of the chuck jaws. The coupling means able to be coupled to a corresponding coupling connection of the drive motor. The movement from the maximum size of the clamping space to the minimum size of the clamping space is executed via the gear train from the drive motor.
