A solid surface clamp that has a top jaw and a bottom jaw, along with alignment structures, is disclosed. The clamp includes a top jaw, a bottom jaw, a bolt attached to the bottom jaw and slideably received through the top jaw, and a nut. The bolt has an alignment cutout, a threaded portion extending from the top jaw and defines a bolt longitudinal axis. The nut is threaded onto the threaded portion of the bolt and transitions the clamp from an open position to a clamping position. The top jaw further includes an alignment hole that contacts the alignment cutout and maintains the top jaw and the bottom jaw substantially fixed relative to each other about the bolt longitudinal axis. The alignment cutout moves relative to the alignment shaft in the direction of the bolt longitudinal axis when the clamp transitions from an open position to a clamping position.

An anti-pivot and lock mechanism for a clamp including a horizontal post connected and moveable relative to a vertical post. The mechanism engages the vertical post and horizontal post above or below a pivot axis of the horizontal post to prevent or minimize pivoting movement of the horizontal post between changes of consecutive clamped workpieces.

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 clamp assembly and method of clamping includes a fixture having a cavity formed by a facing surface. The facing surface in the clamp assembly can define a cavity periphery. In addition, a recess can be provided in the facing surface. An elastic member can be disposed within the recess.

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.

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.

A jig for clamping that includes two or more clamping aid tools for use and mounting with various common tools, including a carpenter, framing and speed square, and various straight edges for easily and accurately positioning various objects, either flat and/or round, magnetic or not. The clamping aids can clamp to round pipes at correct angles while being fitted, secured and/or welded together.

A holding device for a test sheet includes a receiving arrangement for engagement with the test sheet, a handle arrangement connected rigidly to the receiving arrangement for a user for positioning the test sheet, and a pushbutton arrangement for producing a switching signal on the basis of an actuation by the user.

A table tennis assembly apparatus is provided. The table tennis assembly apparatus may provide a base substrate and an overlaying cutting substrate. Along at least one peripheral of the base substrate may be a bar panel and or one or more clamps. Each clamp is for urging a first force distributor to sandwich a table tennis blade, in a uniform manner, against a glued table tennis rubber supported by the base substrate. After a predetermined amount of time a user may swap the first force distributor for a smaller second force distributor, enabling the user to trim the table tennis rubber around the perimeter of the blade.

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.
