Abstract: A workpiece holding device includes a main body having a groove and a bearing plate configured to receive a workpiece; an elastic member mounted in the groove at an angle relative to the bearing plate, and having an engaging portion protruding beyond the groove; and a resisting member having an inclined surface received in the groove. The inclined surface can abut the elastic member. When the resisting member rises it forces the engaging portion of the elastic member to move toward the bearing plate, thus securing the workpiece when present. When the resisting member lowers the elasticity of the engaging portion causes it to move away from the bearing plate, thus releasing the workpiece when present.

Abstract: Embodiments of the invention relate to a rigging table system that delivers the members from the cutting station to a location behind the workers at the rigging table, transports the members vertically below the surface of the floor on which the workers stand, horizontally transports the members underneath the floor on which the workers stand, and delivers the members vertically above the surface of the floor in front of the workers for assembly on the rigging table. The members are delivered through the use of systems that drop, slide, lift, and extend the members of the truss to the desired locations using automatic sensors or call buttons.

The pad assembly is pivotally attached to the hinge and rests flush against the inner wall of the work-piece when the aligning fixture is deployed.

Abstract: A machine tool includes a clamping mechanism for clamping/unclamping rotation of a rotary table. A load is measured when an unclamping command is output and then the rotary table is rotated after a set time set in the timer passes, and the set time of the timer is changed in response to a magnitude of the measured load. In this way, it is possible to prevent the clamping mechanism from being damaged due to a subsequent command given before unclamping ends, and extend a life span of a component.
