Embodiments of the present disclosure can provide an apparatus for circumferentially separating turbine blades. An apparatus according to the present disclosure may include: a length-adjustable elongate member having opposing first and second ends; a first clasp coupled to the first end of the length-adjustable elongate member, the first clasp shaped to at least partially engage an airfoil profile of a first turbine blade positioned circumferentially adjacent to a dovetail slot, relative to a centerline axis of the turbomachine; and a second clasp coupled to the second end of the length-adjustable elongate member, the second clasp shaped to at least partially engage an airfoil profile of a second turbine blade circumferentially positioned adjacent to the dovetail slot, the first and second turbine blades being circumferentially adjacent to the dovetail slot at opposing circumferential ends thereof.

A multipurpose woodworker's clamping and spreading apparatus consisting of an elongated support bar component and a pair of elongated crossbar components held together by the respective vertically inclined and horizontally inclined sleeving elements of each of a pair of a two-way adjustable bar holder components with each crossbar holding, as well, one of each of a pair of adjustable workholder components via the horizontally inclined sleeving member of each and with each workholder component featuring an externally threaded holding bolt threadably held within the bolt holder thereof welded to the sleeving member and with the ball shaped end portion of a small rod extension from the base of the bolt, rotatably holding a shoeholder element, in turn holding a shoe element, the sleeving member portion of which features sleeving for such holding and the base member portion of which serves to hold work for clamping or spreading.

A clamp for use with a cutting machine, the clamp comprising: a clamp frame; a low profile clamp head operatively connected to the clamp frame, wherein the clamp head has a clamping surface for pressing on a work surface of a work piece to hold said work piece; and a fixing element, operatively connectable to the clamp frame, for providing a clamping force to the clamp head by fixing the clamp to a support base for the work piece. In embodiments, the clamp head may have a low profile clamp head, made of plastic to prevent damage to a cutting bit.

A clamping device includes a first holder and a second holder. The first holder includes a first abutting member and a driving member. The driving member is coupled to the first abutting member. The second holder includes a second abutting member. The first abutting member and the second abutting member are oppositely disposed and spaced apart from each other to receive a workpiece. The driving member is coupled to the first abutting member to drive the first abutting member to move in a direction toward the second abutting member to clamp the workpiece between the first abutting member and the second abutting member.

The invention relates to a machining device, in particular for machining workpieces of wood, wood materials, plastic or the like, comprising a workpiece table with a workpiece holder for holding at least one workpiece, and a feeding device for supplying at least one workpiece to the workpiece table, wherein the workpiece can be positioned in three dimensions with respect to the workpiece table. The invention further relates to a corresponding method.

A clamping assembly comprises a body defining a retaining area and a coupling element. The body further includes a first leg having an adjustable engagement member and a second leg positioned at an angle less than 90 relative to a horizontal axis. A rod having a first end coupled to the at least one coupling element of the body. The rod is configured to drive the body in a direction toward the first leg in response to a force directed toward a second end of the rod.

A clamp apparatus including two pairs of first and second clamp arms, which are supported rotatably with respect to a body and are disposed mutually in parallel. First and second cam members including respective cam surfaces are provided on ends of the first and second clamp arms. The first cam members are pressed by rollers upon lowering of a block body under a driving action of a first cylinder that makes up a drive unit. The first clamp arms are rotated to assume a clamped state. The second cam members are pressed by rollers upon lowering of a block body under a driving action of a second cylinder of the drive unit, whereby the second clamp arms are rotated to assume a clamped state.

An electron block frame pouring fixture, and a method of using the fixture, the fixture including a base member having a recessed portion surrounded on each side, the recessed portion configured to receive an electron block frame therein, and a plurality of clamp members connected to the base member proximate each of the respective sides of the recessed portion, the clamp members being configured to be selectively actuated to press a received electron block frame downward into the recessed portion, wherein the recessed portion is configured to prevent lateral movement of the received electron block frame.

Systems and methods for a dual sided clamp. More specifically, a clamp with a channel configured to receive a level on a first side of the clamp, and a triangular shaped cutout configured to receive a shaft associated with different sized valves on a second side of the clamp.

Certain embodiments described herein are directed to devices which can be used to safely secure two or more workpieces to each other, e.g., to secure a cabinet face frame to a cabinet frame. In some examples, the device comprises a base configured to engage a first surface of the first workpiece and to receive an attachment device. The base can also be configured to engage a first surface of a second workpiece. The device may also comprise piston means configured to engage the second workpiece at a second surface. The device may comprise one or more plungers that can be used to actuate the attachment device to permit fastening of the workpieces once properly arranged. Methods of using the device are also described.
