Abstract: An apparatus (100), including: a U-pad body (200) having a bottom (210), a top (212), a front side (214), a rear side (216), a first side (218), a second side (220), a clamping groove (204) that is recessed into the bottom, and a U-pad body pivot feature (202); and an adapter body (300) disposed atop the U-pad body and including an adapter pivot feature (302). The adapter pivot feature and the U-pad body pivot feature cooperate to enable the U-pad body to pivot relative to the adapter body. The apparatus further includes: an anchor nut (400) disposed below the U-pad body; a tightening nut (500) disposed above the adapter body; and a stud (600) that is secured to the anchor nut, that is secured to the tightening nut, and that is passes through the adapter body hole and through the U-pad.

Abstract: A compact tube clamping device for inspecting an electric resistance welded tube quality. A lifting/lowering base including a tube support body is provided onto a fixed base. Clamp claws sandwich the tube support body. A claw drive body lifting/lowering independently of the lifting/lowering base is provided in the lifting/lowering base. Opposite side portions of the claw drive body are connected to opposite clamp claws by links to turn the opposite clamp claws in closing directions by lowering with respect to the lifting/lowering base. A first drive mechanism for the lifting/lowering base and a second drive body for lifting/lowering the claw drive body are provided to the fixed base. A lowering stroke of the claw drive body necessary for closing operations of the clamp claws is partially born by lifting of the lifting/lowering base in transferring the tube, thereby suppressing the lowering stroke of the claw drive body.

Abstract: A jig for securing a thimble, includes a securing block, a pressing plate, a locking assembly. The securing block defines a step hole and a cutout. The pressing plate presses the thimble in the receiving slot. The pressing plate defines an avoiding hole. A pair of short sides and a pair of long sides bound the avoiding hole. The locking assembly includes a pole and an adjusting nut. The pole is inserted in the step hole and the avoiding hole. The adjusting nut includes a pair of long edges and a pair of short edges. The adjusting nut rotates on the pole to align the long edge with the short side to have the adjusting nut press the pressing plate, and rotate on the pole aligning the long edge to the long side locating the adjusting nut in the avoiding hole.

Abstract: In one exemplary embodiment, a low-profile clamping system generally includes first and second elongate supports engageable with an edge portion of a sheet material for supporting at least part of the sheet material against bending. A fastener can releasably couple the first and second elongate supports to the edge portion of the sheet material. The first and second elongate supports define a channel for receiving the edge portion of the sheet material into the channel when supporting the sheet material. In another exemplary embodiment, an apparatus for transporting a sheet material generally includes a frame, at least one wheel coupled to the frame for allowing rolling movement of the frame, and an adjustable vice coupled to the frame for securing a sheet material in the vice on the frame.

Abstract: The present invention provides clamp head comprising an arched body having upper and lower faces, a vertex and opposing unequal length arms. The body is further provided with a through aperture for a bolt or like threaded fastener which extends between the upper and lower faces in the region of the vertex. The aperture in the upper face is oval and tapers outwardly through the body in the direction of the lower face. The arms comprise a reaction arm having at its distal end a reaction face and a clamping arm having at its distal end a clamping face, the reaction and clamping faces being provided with respective formations. The formations of the reaction arm extend in a direction which is substantially transverse to the direction of the formations of the clamping arm.

Abstract: The invention relates to a method for reducing vibrations of a machine element (9) and/or a workpiece (5) in a machine tool, a production machine and/or in a machine which is embodied as a robot. A clamping force (F), which is used to lock the workpiece (5) and which makes the workpiece holder (2a, 2b, 2c, 2d, 2e, 11a, 11b) act upon the workpiece (5), is modified when vibrations occur. The invention also relates to a corresponding machine. Due to said invention, vibrations of a machine element (9) and/or a workpiece (5), which occur during a machining process, are reduced.

Abstract: Apparatus and method to aid in the reproducible and reversible tensioning of flexible substrates, such as polyimide or other file, to ensure planarity before, during, and after processing while mounted in tensioning apparatus.

Abstract: A swing-arm clamp is provided. The swing-arm clamp has a locating member that is movable in concert with a rod which is disposed in the clamp. The locating member engages a guide when the arm is located in a first position and separates from the guide when in a second position.

Abstract: An apparatus for manufacturing a semiconductor device includes a rotatable spindle, a head detachably connected to the spindle, and a clamp for clamping outer circumferential surfaces of the spindle and the head to one another so that the head may be driven by the spindle. The clamp has an annular clamping frame sized to encircle the outer circumferential surfaces of the spindle and the head, a projection disposed on one end of the clamping frame, a lever pivotally connected to the other end of the clamping frame, and a fastener pivotally connected to the lever and configured to hook over the projection. Once the fastener is hooked over the projection, the lever is pivoted to force the ends of the annular clamping frame together and thereby produce a clamping force that secures the spindle and head to one another. The clamp can be manipulated easily and with a simple motion to clamp the head to the spindle. Also, the parts of the clamp generate little mechanical friction.

Abstract: A quick-disconnectable device with a screw piece, a first threaded part and a second threaded part, the threaded of which fits with the first threaded part, wherein the screw piece has a straight guide for the first threaded part, and the screw piece has a radial bearing and an axial bearing for the second threaded part, the longitudinal direction of the straight guide and the axis of rotation of the radial bearing are arranged parallel to one another, the two threaded parts are guided at a distance at which the mutual engagement of the two threaded parts is possible, the second threaded part has an external thread, and is equipped with a recess which completely interrupts the engagement of the threads at least in a specific rotary position An embodiment as a compact light and simple quick-acting clamping means for variable clamping geometry for articles to be measured on automatic 3D-measuring machines or as a spindle drive with high-speed disengagement.

Abstract: A machine tool clamp includes an elongated clamping member with its mid-section anchored at an adjustably spaced distance above a base plate. The front end of the clamping member is adapted to clamp a work piece to a machine tool work platform. The rear end or heel of the clamping member bears pivotally on the base plate in such a manner that the adjustable anchor of the mid-section is a movable fulcrum. A height adjustable mechanism with a large mechanical advantage is positioned in the heel of the clamping member to lever the clamping member about the adjustable fulcrum to clamp the front end on a work piece. The height adjustable mechanism can be a screw, eccentric cammed lever, hydraulic or pneumatic cylinder, or other suitable mechanism.
