A workpiece clamping assembly includes a fixed member and a movable member and the movable member is associated with a motor for movement toward and away from the fixed member. The motor is in communication with a controller that selectively signals for movement of the movable members in response to an operator's command.

The present disclosure relates to a gripper device which comprises: a belt pulley driven by a power-driven motor; a belt and another belt pulley driven by the above belt pulley; a ball screw driven and rotated by the belt pulley; nut brackets driven to be shifted along two rigid guideways by two reverse threads at both sides of the ball screw, respectively; a plurality of steel balls, which are installed between a nut bracket and a rigid guideway and sustain more stresses when a workpiece is clamped between two upper slide on the nut brackets.

Attachments for a clamping device can be used to increase the contact area between the jaws and the object to allow the clamping device to handle irregular objects, such as non-flat panels of metal, granite, ceramic, glass, quartz, or concrete plates. The attachments can include plate assemblies to be attached to the sides of the irregular objects. The attachments can include jaw plate assemblies to be attached to the sides of the jaws of the clamping device.

A clamping force visualization device, including a first clamping body (01) for clamping an object; the first clamping body (01) is telescopically assembled on a base (14), an elastic element (110) is provided between the first clamping body (01) and the base (14), and a clamping force scale (11) and a reading indicator (15) are respectively provided on the first clamping body (01) and the base (14); when the first clamping body (01) clamps the object, the elastic element (110) measures a clamping force and the reading indicator (15) points to the clamping force scale (11) for reading, so that the magnitude of the clamping force can be intuitively seen and read during clamping, thereby achieving accurate clamping. A clamp including the clamping force visualization device is also involved.

A clamping apparatus includes: a support member (19) inserted in a leading-end-side portion of the housing (1) so as to be movable in its axial direction; a resistance giving mechanism (34) configured to give resistance to axial movement of the support member (19); and an engagement maintaining mechanism (26) configured to maintain engagement between a wedge surface (24) of a clamp rod (7) and a locking member (23). When the clamp rod (7) is driven toward a leading end side for unclamping action, the clamp rod (7) moves the locking member (23) toward the leading end side via the support member (19) after the locking member (23) moves radially inward.
