The present disclosure is directed to a coupling assembly for a turbomachine. The coupling assembly includes a liner and a sleeve at least partially positioned circumferentially around the liner. A frame is positioned between the liner and the sleeve. The frame includes a first side wall, a second side wall, and a base wall extending from the first side wall to the second side wall. A block is positioned between the liner and the sleeve and is movable relative to the frame to permit the block to move toward and away from the base wall. Moving the block away from the base wall causes the block to exert an inward force on the liner and the base wall to exert an outward force on the sleeve.

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.

A vise is provided with a movable jaw including a threaded hole in a channel; an actuator in the channel and having a hole through an arcuate surface; a limit member in the channel and having front and intermediate cavities and a rear groove; a first plate member in the front cavity and having a through hole; a third plate member in the intermediate cavity and having a through hole; and a second plate member sandwiched between the first plate member and the third plate member and having a hole through a convex surface; and a slide sleeve including a tunnel, an intermediate thread engaging the threaded hole, a front annular flange in the rear groove, a front recess surrounded by the annular flange, and a biasing member in the front recess and urging against the third plate member; a handle; and a stationary jaw including a slide bar.

A universal tool holder configured for use with a machine tool is provided. The universal tool holder may be used for securing the machine tool in a relatively fixed orientation; for mounting and dismounting modular tools for milling and lathe computer numerical controls (CNC); and for assembling extension adaptors, reduction adapters, front clamp adapters, cutters, and other similar tools.

A seismic sway brace fitting for a seismic brace includes a first jaw defining a threaded opening configured to receive a fastener to secure the seismic sway brace fitting to the seismic brace, and a second jaw. A pin connects the first and second jaws to one another. The first and second jaws define a space configured to receive an end portion of the seismic brace. The threaded opening is aligned with the space such that the fastener extends into the space to engage the end portion of the seismic brace when the fastener is received in the threaded opening to secure the seismic brace to the sway brace fitting. The first jaw includes at least one brace bearing surface configured to engage an end of the seismic brace to inhibit the rotation of the first jaw relative to the second jaw.

An output rod (20) of an electric clamping device includes: a tubular power transmission member (25) screw-connected to a decelerator (6); and an output rod main body (24) disposed radially inward of an inner peripheral surface of a cylindrical hole of the power transmission member (25) with a clearance between the output rod main body (24) and the inner peripheral surface. The output rod (20) further includes: a rotation preventing mechanism (26); a lock-side driving mechanism (27, 42), a release-side driving mechanism (28), and an output rod guide mechanism (29).

A portable workstation platform is disclosed. The portable workstation platform includes a base and an accessory mount secured to a first surface of the base. An accessory locking fixture is coupled to the accessory mount. A pair of clamp fastening tabs is secured to the first surface of the base. Further, a multi-functional clamping device that includes the portable workstation platform is disclosed. The multi-functional clamping device includes a handle portion comprising a vice grip handle and a clamping portion coupled to the handle portion. The clamping portion includes opposing clamps, wherein the base of the portable workstation platform is one of the clamps and the pair of clamp fastening tabs on the base is configured to receive the clamping portion. A second accessory mount may be coupled to the clamping portion of the multi-functional clamping device.

The present invention relates to a quick clamping device. A pressing flange and a top plate are respectively installed on both sides of a bracket; one end of a top rod is rotatably connected with the top plate, and the other end is in threaded connection with a center pressing element; a slip ring copper sleeve is sleeved on the center pressing element; a synchronous slip ring can be sleeved outside the slip ring copper sleeve relatively movably; the outer end part of the slip ring copper sleeve is provided with a copper sleeve flange; a spring sleeved on the slip ring copper sleeve is arranged between the synchronous slip ring and the copper sleeve flange; both ends of the spring are respectively abutted against the synchronous slip ring and the copper sleeve flange; a plurality of pull rods are evenly distributed along the circumferential direction of a clamped element; one end of each of the pull rods is respectively hinged to the center pressing element, and the other end is a pressing end; the clamped element is positioned between the pressing flange and the pressing end of each pull rod; a connecting rod is connected between each of the pull rods and the synchronous slip ring; and both ends of the connecting rod are respectively hinged with the pull rods and the synchronous slip ring. The present invention has the advantages of novel structure, simple operation, small size, and the like.

A clamp for use with an impact tool; the clamp having a nut for use with impact tools includes a screw on top, a safety handle, and a hole for carabiner clip. In use, a user adjusts the top screw to a length option desired, such that it doesn't slide onto object to be clamped. The clamp further comprises a grip on the safety handle. The clamp provides faster and more efficient use when using an impact tool.
