A clamping device is disclosed having a rigid frame and a concavity for accepting items to be clamped together, a clamping action upon items entering into the concavity being facilitated by a contacting member in conjunction with a force-maintaining member and a displacement-limiting element to readily accommodate a range of clamped item dimensions without requiring separate opening or tightening adjustments to be performed by a user while applying the clamping device.

A table assembly is used to support a workpiece to facilitate bending of the workpiece. The table assembly is attached to a press brake system and include a base and a clamp. The clamp is movable relative to the base to enable placement of the workpiece onto the base, and the clamp secures the workpiece to the base to block relative movement between the workpiece and the press brake system without additional user operations. The workpiece is secured via the table assembly without a manual force (e.g., to hold the workpiece in place) while the press brake system operates to bend the workpiece. The table assembly reduces, limits, or eliminates certain user operations during metalworking. The table assembly improves user experience (e.g., reduce an amount of manual labor) and/or efficiency associated with press brake operations.

A clamp assembly that may be used for securing to a raised portion of a surface. The clamp assembly comprising a mounting body of a general block shape having a slot for receiving the raised portion formed in a bottom surface of the mounting body attaching the clamp assembly thereto. The clamp assembly is configured with one or more pins that may be formed in a substantially elongated cylindrical shape. The pins may be configured to be received in one or more push-pin holes formed in the mounting body, whereby the push-pin holes extend to the slot from a side surface of push-pin holes. The clamp assembly includes a fastening element adapted to be received in a fastener hole formed adjacent the push-pin holes in the side surface of the mounting body. The fastening element is configured to secure, attach and hold the clamp assembly to the standing seam by forcing the pins against the raised portion of the surface disposed in the slot.

Disclosed is a rotary actuated axial clamp that includes a primary fixture, having a rotatable primary clamp, having primary clamp fingers that engage secondary clamp fingers on a stationary secondary clamp. The primary fixture is attached to a positioner, while the secondary fixture is attached to the work piece. Different secondary fixtures can be utilized to fit the shape and size of the work piece, while maintaining a secondary clamp that is able to engage the primary clamp of the primary fixture. The primary fixture can consequently be utilized with numerous different work pieces having different shapes and sizes by simply modifying a secondary fixture to adapt to the size and shape of the work piece. Roller engagement of the primary clamp and secondary clamp reduces the force required to clamp and unclamp the primary and secondary fixtures. This reduces problems associated with attaching a work piece to a positioner.

A weight-actuated panel holder is disclosed herein. The weight-actuated panel holder includes a first jaw member; a second jaw member pivotally coupled to the first jaw member, the first and second jaw members cooperating to a form a slot for receiving an end portion of a panel, an opening width of at least a portion of the slot being configured to be reduced when a weight of the panel actuates the first and second jaw members towards a closed position; and a clutch mechanism coupled to at least one of the first and second jaw members, the clutch mechanism configured to bias at least one of the first and second jaw members in the closed position.

An apparatus configured to structurally replace a cracked weld in a nuclear plant may include: a first body portion that includes a first gripping portion; a second body portion that includes a second gripping portion; a wedge portion between the first and second body portions; and/or an adjustment portion. The first body portion may be configured to slidably engage the second body portion. The wedge portion may be configured to exert force on the slidably engaged first and second body portions. The adjustment portion may be configured to increase or decrease the force exerted by the wedge portion on the slidably engaged first and second body portions. When the adjustment portion increases the force exerted by the wedge portion on the slidably engaged first and second body portions, a distance between the first and second gripping portions may decrease.

Disclosed is a configurable table that uses configurable mounting pieces to mount a work piece on the configurable table at a predetermined location. The configurable table includes a fixed portion of a mounting clamp that can engage a rotatable portion of a mounting clamp on a positioner or other device. The positioner can then rotate the configurable table and work piece to various orientations for performing horizontal welds, using robotic welders, as well as machining and cutting. The configurable table can also be used for initial fabrication, cutting, or working, which eliminates the need for separate fabrication and finish welding tables.

A welding clamp system using a fixture plate with a bulkhead that allows the clamp system to be coupled to a robotic arm. The robotic arm supplies air and electricity through pneumatic and electrical ports, enabling operation of the clamp system. The air is routed to pneumatic cylinders, which power a pneumatic clamp mechanism that moves sliding clamp fixtures along tracks. The sliding clamp fixtures press a work piece against immobile clamp fixtures, allowing a work piece to be secured and held during welding. Presence of a work piece is detected by proximity sensors which are mounted into the fixture. The clamp system allows a robotic arm to grab a work piece from a supply area, initiate and complete welding of the work piece, and then release the work piece onto a discharge station for removal of the completed work piece.

A clamping system includes a housing, a clamping lever pivotally coupled relative to the housing, a clamping arm pivotally coupled relative to the housing and the clamping lever, and an expandable link coupled to the clamping arm. The clamping lever and the clamping arm are rotatable from an open position to a closed position. A method of mounting a device on a substrate using the clamping system is also provided.
