A clamp on straight edge device for guiding for a tool includes a slot that is positioned longitudinally through a bar. A pair of coupling assemblies is slidably positioned in the slot. The coupling assemblies are selectively couplable to the bar so that each coupling assembly is fixedly positionable within the slot. Each coupling assembly is configured to position in abutment to a respective edge of a workpiece. The coupling assembles then are coupled to the bar to couple the bar to the workpiece with the bar extending linearly between the pair of coupling assemblies across a respective face of the workpiece. A user is positioned to selectively mark, score, perforate, cut, or otherwise alter the workpiece along a respective opposing side of the bar using a tool, such as a hand held powered cutting tool or the like.

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.

A work table includes a baseplate, a plurality of levers, a clamp plate, a lock mechanism, and an unlocking mechanism. The plurality of levers are disposed on a concentric circle on the baseplate. Guide bars protrude upward from the plurality of levers. The plurality of levers are each disposed to be movable in a radial direction of the circle. The clamp plate is placed on top surfaces of the levers. The clamp plate has elongated holes in the radial direction through which the guide bars penetrate. The lock mechanism urges the clamp plate downward such that the respective levers are fixed in a manner sandwiched between the baseplate and the clamp plate. The unlocking mechanism releases the fixing of the respective levers by the lock mechanism.

A workpiece clamping device able to clamp a first workpiece and a second workpiece placed on the first workpiece. The workpiece clamping device includes a receiving base on which the first workpiece is to be placed, a first clamping mechanism for clamping the first workpiece, and a second clamping mechanism for clamping a second workpiece placed on the first workpiece. The first clamping mechanism has a first clamp section and a second clamp section, which are provided on the receiving base so as to open and close. The second clamping mechanism has a third clamp section and a fourth clamp section, which are provided on the receiving base so as to open and close, to retain the second workpiece at a predetermined position with respect to the first workpiece.

The present invention provides a clamp for holding a workpiece that is particularly suitable for use in CNC machining. The clamp is particularly useful for use in picture-frame machining techniques as it allows a workpiece to be held in a position wherein a machine can have substantially unencumbered access to both sides of the workpiece without the need to remove the workpiece from the clamp. The clamp comprises a frame comprising a base, a first arm, and a second arm, the first arm and the second arm each mounted to the base at an inner end such that they are parallel with one another.

A straight edge bar clamp spreader comprises a straight edge bar, an inner channel portion, parallel channel portions, and two-way bosses or divots, a clamp, and a clamp-spreader. The inner channel portion is provided along an elongated central region of the bottom surface of the straight edge bar with a constant cross-section. The parallel channel portions are provided along two elongated parallel regions of the top surface of the straight edge bar. The two-way bosses or divots are provided across and on an inner surface of the inner channel portion of the bottom surface and an outer surface of the top surface and configured to define the predetermined stopping positions for two-way movements along the bottom surface or the top surface. The clamp is installed in the inner channel portion of the bottom surface. The clamp-spreader is installed in the pair of parallel channel portions of the top surface.

In a clamping device (1), in particular vice, the clamping device comprising: a housing (2) which is U-shaped in cross-section and in which one or two guideways (8) extending in a linear direction are incorporated, at least one base jaw (11) which is mounted in the guideway (8) and in which an internal thread (12) is provided, and a drive spindle (9) which is rotatably mounted in the respective housing (2), is arranged parallel to the guideway (8) and is driveably coupled to the respective base jaw (11),
the threads (10) worked into the drive spindle (9), through which the torques from the crank are transmitted for the linear displacement of the base jaws (11), should be permanently encapsulated in a watertight and airtight manner irrespective of the position of the base jaws (11) or the drive spindle (9), and on the other hand the adjustment travel (s) of the base jaws (11) or clamping jaws (13) should be as large as possible in order to clamp workpieces with configurations that can be completely different without the need for time-consuming and complicated conversion measures.

This is achieved in that a right-hand thread and a left-hand thread (10) are worked onto the drive spindle (9) in regions, in that the respective thread (10) of the drive spindle (9) is enclosed or encapsulated by a cover sleeve (21), in that the cover sleeve (21) has a right-hand thread and a left-hand internal thread (22), which are driveably coupled to the respective thread (10) of the drive spindle (9), in that a right-hand and a left-hand external thread (23), which is in engagement with the respective internal thread (12) of the base jaw (11), is worked on to the cover sleeve (21).

An inline clamp system having a base, a shoe having a plurality of teeth and a scroll wheel having a helical feature on a cone shaped surface. The helical feature of the scroll wheel meshes with the teeth of the shoe such that rotation of the scroll wheel in a first rotational direction causes linear movement of the shoe in a first linear direction and rotation of the scroll wheel in a second rotational direction causes linear movement of the shoe in a second linear direction, the first rotational direction being opposite the second rotational direction and the first linear direction being opposite the second linear direction. The scroll wheel rotates around an axis of rotation at a slight angle to the linear plane of movement of the shoe such that the helical feature engages the teeth only on one side of the axis of rotation.

A rail clamp latch holder is provided. The rail clamp latch holder includes a grippable portion and a rail portion disposed at a forward side of the grippable portion. The rail portion includes first and second pairs of opposed latches which are configured to latch onto a rail and which are disposed at first and second longitudinal ends of the rail portion, respectively, a tab, a locking pin and an elastic member. The tab is insertable into a rail latch. The elastic member extends along a longitudinal axis of the rail portion and elastically couples the locking pin and the tab.
