Abstract: Clamp systems include multiple, separate clamps joinable to components subject to relative rotation. Clamps may have similarly-positioned features to simplify installation and/or removal about a small area for all clamps in the system. Each clamp cannot freely rotate relative to an adjacent clamp but does not pass vertical loads to an adjacent clamp. Clamps may use mating shapes like an extension and recess to limit rotation. Clamps fit to the perimeters of components to which they individually secure by biasing against the components. At least one clamp has a transitional surface to provide space between the clamp and component to provide containment to a weld or other joining structure. Clamp systems can be tightened by included fasteners. Crimp nuts or other locking structures can preserve the biased and secured nature of the clamps and underlying structures. Clamp systems may be used to secure or repair a lifting rod assembly.

The vacuum adsorption clamping system with multiple clamping modes can be adaptively adjusted according to the process stage of curved components.

Abstract: A power tool has a body, a trigger, a motor, a shaft set, a ball screw, and a pre-fastening module. The pre-fastening module has a first pre-fastening detecting member and a second pre-fastening detecting member. The first pre-fastening detecting member is moved with a connecting shaft of the shaft set in an axial direction. The second pre-fastening detecting member is located on a moving path of the ball screw. When a threaded spindle of the shaft set is inserted in a rivet nut and the connecting shaft is pressed to move inward the body, the first pre-fastening detecting member is moved to align with the second pre-fastening detecting member, and the motor is started automatically to drive the threaded spindle to rotate relative to the rivet nut. The motor will be stopped automatically after the rivet nut is pre-fastened on the threaded spindle, and this is convenient in use.

A condition of the first IBR is determined based at least in part on the change in the value of the inherent blade section vibratory property. The first IBR is maintained based on the condition.

The active apparatus includes a motor that drives a shaft in first direction to advance a plunger towards the passive apparatus to transition the fastener to the locked state. The plunger includes a tapered distal end that mechanically engages a locking body. The locking body is moved laterally by the tapered distal end to apply a force to a locking frame that is located in a slot defined in a housing of the passive apparatus. The force causes the mechanical fastener to be locked. To unlock the mechanical fastener, the motor drives the shaft in a second direction to retract the plunger away from the passive apparatus.
