    • A vise (10) having a control aperture (74) at an accessible end (54) of a screw rod (50) and extending along the rotational axis (52) thereof. The aperture (74) is sized and shaped to accept the anvil (72) of a drive mechanism (70) so that upon rotation of the anvil (72) along its torque axis (80), screw rod (50) rotates about its rotational axis (52). At least one of a pair of jaws (18, 20) is operatively associated with screw rid (50) to thereby vary the spacing (34) therebetween as screw rod (50) rotates under control of the anvil (72).

    • The present invention relates to a self-centering vise having reduced vertical size, in particular for applications on machining centers and CNC numerical-control machines, which is however capable of exerting on the workpieces a high force exceeding 2000 kg. The vise comprises a body, two or more jaws constrained to the body and actuators of the jaws. The jaws can be moved close to and away from a workpiece gripping axis, in response to the stresses imparted by said actuators. Each actuator comprises a thrust element susceptible to displacements in response to the stresses imparted by a pressurized fluid fed to the vise. Each jaw comprises two guides inclined and symmetrical with respect to the displacement direction of the same jaw, and the thrust element of each actuator comprises two walls inclined and symmetrical with respect to the displacement direction of the same thrust element. Each actuator exerts its thrust simultaneously on two jaws, by slidingly engaging the guides of two jaws with its own inclined walls, according to a configuration that can be defined double inverted wedge configuration. This feature makes the vise self-centering and effective.

    • A movable clamping element (56) engages a workpiece, whereby a spring (86) is compressed, limiting the amount of clamping force applied to the workpiece. A retainer nut (88) is selectively moved through the use of the tool to a selectable position along a threaded shaft (80) to adjust the spring compression, hence the clamping force. After initial setup, an electrochemical actuator (110) is actuated to melt a polymer, forcing a piston assembly (118, 120) and a bearing (84) to shift the threaded shaft (80) longitudinally against the spring, moving the clamping elements apart a short distance to release or receive a workpiece. The electrochemical actuator is then deactivated, allowing the spring to expand, clamping the workpiece between the clamping elements with the selected force.
    • 本发明涉及一种与工件接合的可移动夹紧构件(56),弹簧(86)被压缩以限制施加到工件上的夹紧力的量。 使用工具将固定螺母(88)选择性地移动到螺纹杆(80)上的可选位置,以调节弹簧的压缩并由此调节夹紧力。 在初始设定之后,开始电化学致动器(110)以混合聚合物,由此迫使活塞组件(118,120)和轴承(84)纵向移动螺纹杆(80)克服弹簧,并且 将夹紧元件移动一小段距离以释放或接收零件。 然后电化学致动器停用,允许弹簧展开并利用选定的力将工件夹紧在夹紧构件之间。
