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 fixture for holding a part comprises a frame supporting a guide plate. A controlled engagement device passes through the guide plate and is arranged to be advanced incrementally towards a first end of a fulcrum beam. A second end of the fulcrum beam is connected to a linkage arm, the linkage arm passing through a gap in the guide plate. An end of the linkage arm distal to the fulcrum beam has a swivel clamp mounted thereto. A support is arranged to face the swivel clamp and defines a space there between, the space being configured to receive a part to be clamped in the fixture.

A clamping device includes a first, a second clamping member, a first, a second connecting rod, and an elastic member. The first clamping member includes a first side and a second side opposite to each other. The second clamping member includes a third side and a fourth side opposite to each other. The first connecting rod is pivotally disposed between the first side and the third side. The second connecting rod is pivotally disposed between the second side and the fourth side. The elastic member is connected between the third side and the first connecting rod. The elastic member provides a restoring force to make the first connecting rod rotate relative to the second clamping member, to drive the second connecting rod and the first clamping member to rotate, so that a distance between the first and the second clamping member is shortened to clamp an object.

An electric clamp apparatus includes a body, a rotary drive unit which is driven rotatably by an electric signal, and a clamp arm disposed rotatably with respect to the body. By driving the rotary drive unit, a drive force is transmitted to the clamp arm through a drive force transmission mechanism, whereby the clamp arm is rotated via a link arm through a predetermined angle with respect to the body, and a workpiece is clamped between the clamp arm and a support member of the body. Further, rotational operation of the clamp arm is regulated by abutment of a sub-roller against an inclined portion of a displacement body.

A tool for removing a component from a turbomachine is provided. The tool includes a body having an alignment portion and a connection portion. The alignment portion defines a longitudinal axis and a cross sectional shape complementary to a slot defined in a rotor wheel of the turbomachine. When the tool is positioned in the slot, the connection portion is configured to contact the component. The tool additionally includes a force section connected to the body and configured to transfer a force to the connection portion in a direction substantially parallel to the longitudinal axis of the alignment portion.

In an electric clamp apparatus, a drive unit including a motor is disposed on an end of a body on which a clamp arm is rotatably supported. The drive unit includes a hollow housing connected to the body, and a motor unit, which is configured to be accommodated in the interior of the housing. After the motor unit has been inserted into the interior of the housing from one end side thereof, two lock plates, which are disposed on a frame of the motor unit, are rotated, whereby holes of the lock plates are made to engage with projections of the housing. As a result, the motor unit is fixed in a state of being accommodated in the housing.
