A press tool employs a drive system that allows a first portion to be displaced relative to a second portion. A drive surface is supported by the second portion. A receiving member defines an engaging surface and a receiving cavity. The receiving member is supported by the first portion along a drive axis extending through the drive surface. Operation of the drive system displaces the drive surface relative to the receiving member.

A clamping jaw for the clamping of a workpiece, with a body and several clamping inserts arranged in mounting openings of the body made of a sintered material. The clamping inserts are designed in the form of cylindrical pins projecting relative to an end surface of the body and inclined relative to a lower base surface of the body with a clamping edge for forcing the clamping inserts into the workpiece.

The invention relates to converting a ball and socket style vise into a positioning vise. Jewelers and hand engravers and metal working artists utilize traditional ball vises for holding and spinning an object that is being worked on. The present invention provides a way to retrofit these traditional ball vises with a linear positioning top portion assembly.

A fixture for a thin-walled workpiece includes two clamping devices. Each of the clamping devices has a metal carrier and a damper. The metal carrier has a carrying portion and a supporting portion, where the supporting portion has a stair portion having a plane surface and a standing surface with a slope. The damper has a metal clamping portion and a damping portion. One end of the metal clamping portion is formed as an inclined surface. The damping portion has at least two elastic layers and at least one metal layer, which are laminated in an interlacing arrangement with the same slope of the inclined surface. One of the elastic layers is disposed to connect the inclined surface. The end of the metal clamping portion connecting the elastic layer is located on the stair portion, while the opposite end of the metal clamping portion protrudes out of the supporting portion.

The system includes a forward clamping assembly, steady rests and compression assembly upon which the fuselage of a rocket is secured. The forward clamping assembly secures the forward fuselage of the rocket and the steady rests secure the middle fuselage of the rocket. The compression assembly includes a fluted nozzle rotator which engages the flutes of the nozzle of the rocket. Rotation of the nozzle rotator results in torque being applied to the joint connecting the rocket nozzle with the motor casing of the rocket so as to allow insertion or removal of an Ortman key that secures the motor casing and nozzle.

A vise including a body, a threaded shaft extending through or positioned adjacent to the body, and a block coupled to the body and spaced away from an axial end of the shaft. The vise further includes a pair of carriages carried on the shaft and configured such that rotation of the shaft about a central axis thereof causes each carriage to move axially along the shaft. The vise also includes a pair of clamps releasably coupled to the shaft and positioned adjacent to the block on opposite sides thereof. Each clamp is adjustable axially along the shaft to enable adjustment of an axial position of the shaft relative to the block.

A vise includes a pair of clamping jaws, such as a stationary and a movable jaw which are mounted on a saddle which may be connected to a trailer hitch mount or a workbench. The elements of the vise may be constructed from formed sheet metal. The vise may permit gross adjustment of the relative positions of the jaws via a first saddle sliding mechanism and fine adjustment of the relative positions thereof, such as via a screw mechanism which moves one jaw along the saddle.

A method for rerounding a tubular structure includes the steps of: (1) inserting the tubular structure into a rerounding tool that is in an open position, the rerounding tool having a first block with a first semi-circular trough formed therein in a first surface thereof and a second block with a second semi-circular trough formed therein in a second surface thereof, the tubular structure being laid within the first trough; and (2) closing the rerounding tool by bringing the first surface into contact with the second surface such that the tubular structure is also received within the second semi-circular trough resulting in rerounding of the tubular structure due to the first semi-circular trough and the second semi-circular trough defining a cylindrical cavity.

A clamp release mechanism is provided. The clamp includes a body, a shaft slideably coupled to the body, a fixed jaw, and a moveable jaw coupled to the shaft. A locking component actuates between a locked position and an unlocked position. When in the locked position, the locking component biases the shaft to remain stationary with respect to the body. The clamp includes a securing component pivotally coupled to the locking component, and a biasing element that biases the securing components towards the shaft.

A frame block clamp includes first and second block portions dimensioned and configured to provide first and second tube receiving apertures for snugly receiving a predetermined tube; and to provide first and second V configured recesses in respective first and second side portions when portions of said first and second block portions are cooperatively engaged. The frame block clamp further includes a retaining spring dimensioned and disposed to urge together predetermined portions of the first and second block portions to ultimately secure a tube in the first or second receiving apertures. The frame block clamp is ultimately secured in a vise to allow a person to service the tube secured in the first or second receiving aperture.
