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.

Clamping or gripping device with a main body, with guide portions provided on the main body, with jaws which are movable along the guide portions in a direction of movement, which can be moved between an inner stroke position and an outer end-of-stroke position, the jaws each having a row-of-teeth portion with, in each case, a length extending in the direction of movement, and with multiple pinions, the axes of rotation of which lie in a plane lying parallel to the respective row-of-teeth portions, the pinions interacting with the respective row-of-teeth portion to drive the jaws.

A workholding clamp for securing a workpiece to a work surface comprised of a fixed body secured to the work surface and having a first inclined surface; a sliding jaw having a second inclined surface residing against and parallel to the first inclined surface, a clamp face and at least one obround opening; and at least one clamping fastener residing within the at least one obround opening and being tightened to cause the second inclined surface to slide against the first inclined surface. A workholding pivot clamp for securing a workpiece to a work surface, and a work stop for reliably locating a workpiece relative to a work surface are also described.

An apparatus for processing a semiconductor substrate, such as an optical device, is described herein. The apparatus includes a substrate carrier which is configured to enable a processing chamber configured to process larger substrates to process a smaller substrate without retrofitting the processing chamber. The substrate carrier includes a carrier base and a clamp ring. The carrier base includes a plurality of gas channels formed within a substrate pocket. The clamp ring is disposed on the carrier base and over the substrate and holds the substrate in place. The clamp ring is either weighted or configured to be help by a separate chamber clamping mechanism.

A clamp and manifold apparatus comprising internal fluid-flow passages and such apparatus in a system. One embodiment of the apparatus of the invention comprises a clamp body; a manifold, an attachment feature for attaching to a fixture system; a clamping surface; at least one fluid flow passage inside the manifold having at least two endpoints; a first port disposed adjacent to the manifold and in fluid communication with one endpoint of the at least one fluid flow passage inside the manifold; and, a second port disposed adjacent to a second surface of the manifold in fluid communication with the second endpoint of the at least one fluid flow passage inside the body. An embodiment of the system of the invention comprises said clamp and manifold; a fixture; a fluid distribution pump; and fluid routing means connecting the fluid distribution pump and the first port of the apparatus of the system.

A toolless clamp comprises a shaft, a base, a latch, a first biasing member, and a clamping member. The base has a base bore configured and arranged to slidably receive a portion of the shaft. The latch has a latch bore configured and arranged to slidably receive a portion of the shaft and a portion of the base. The first biasing member is configured and arranged to bias the latch in a first direction away from the clamping member in an unclamped position and bias the shaft and clamping member in a second direction toward the base in a clamped position. The clamping member is operatively connected to a proximal end of the shaft and is configured and arranged to disengage the connecting member when the latch is in the unclamped position and engage the connecting member when the latch is in the clamped position.

Disclosed is a handle clamp for an exothermic mold. The clamp includes a pair of legs, each having a plurality of rods that are shaped to fit into engagement holes on sections of the mold. The rods of each leg engage with one section of the mold. Engagement brackets are rotatably disposed on one or more or the rods. The brackets each have a thumb bolt that can be extended toward a mold section connected with the clamp. When engaged with the mold section, the thumb bolt stabilizes the mold section on the handle. A detent mechanism is provided between the bracket and the leg of the handle. The detent mechanism releasably holds the bracket in one of a selected plurality of rotational positions with respect to the rod. By selecting different rotational positions for the brackets, the handle can be configured to engage with different configurations of mold. The thumb bolts that are biased toward the mold section by a spring. The bolts include a key that can be aligned or misaligned with a key slot on the bracket. By aligning the key with the key with the key slot, the bolt can be moved toward or away from the mold section under the biasing force of the spring. By misaligning the key and key slot, the bolt can be locked into engagement with the mold section or else held in a disengaged position.
