The clamping device includes a pair of clamping members arranged in positions to clamp a rib (target portion to be clamped) of a workpiece and having contact surfaces to make contact with the rib; supports configured to support each of the pair of clamping members so as to be able to advance and retreat along a prescribed advancing/retreating direction relative to the rib, and to operate each of the pair of clamping members so as to clamp the rib when advancing; guiding units configured to make each of the pair of clamping members movable in a prescribed positioning direction due to a reaction force occurring when the pair of clamping members clamp the rib; and coil springs (biasing members) configured to elastically bias the pair of clamping members in a direction opposite the positioning direction, thereby capable of positioning the workpiece with high precision without damaging the workpiece.

The present invention relates to a work holding and clamping device, which increases the usable span to almost twice its stored length. This clamping device has an inner and outer assembly which are nested, and each assembly is made of a rectangular tube with a jaw affixed to one end. The inner assembly contains a locking mechanism to allow for length adjustment. When arranged so that the jaws are on the same side of the respective assemblies, the clamp is capable of a span that is almost equal to the length of the inner assembly. When arranged so that the jaws are on opposite sides of the respective assemblies, the clamp is capable of a span that is almost equal to the sum of the length of the inner assembly and outer assembly.

A clamp, comprising a guide rail, a fixed jaw, which is arranged on the guide rail, a sliding jaw, which is displaceable on the guide rail, and at least one spindle, which is arranged displaceably on the sliding jaw and on which there is arranged or formed a pressure piece, with an actuation device, which is spaced from the at least one spindle and which actuable by an operator in order to control a displacement movement of the at least one spindle, with a force application device, which acts on the at least one spindle and by means of which a displacement movement of the at least one spindle is achievable, and with a transmission device, which connects the actuation device and the force application device.

Modular carriage for varying spacing between ends of polymer pipe during fusion. The modular carriage includes a fixed jaw; an inner movable jaw; an outer moveable jaw and a plurality of guide rods. The fixed jaw being adapted for tool free engagement with the terminal ends of the plurality of guide rods. A carriage cylinder is associated with at least two of the guide rods and mounted for reciprocal travel along the length of its associated guide rod. The movable jaws being adapted for tool free engagement with at least two carriage cylinders for reciprocal travel therewith. A combined hydraulic cylinder/guide rod includes a guide rod with an integral guide rod piston, a cylindrical tube, and a guide rod gland on each end of the cylinder tube.

A clamp including a first jaw member having a camming surface, a second jaw member pivotable with respect to the first jaw member, a first biasing member biasing the first and second jaw members to a first position; and a locking mechanism that includes a cam or roller for cooperating with the camming surface of the jaw member, and a second biasing member biasing the cam or roller against the camming surface to lock the first and second jaw members in a second position. An optional alignment collar can be used to align components of the filtration apparatus prior to clamping. Filtration apparatus including the clamp, and also optionally including the alignment collar, is also disclosed.

The present disclosure includes a part hold-down assembly for retaining an oversized part. The part hold-down assembly is aligned along a central force axis and applies a downward force onto the part. The part-hold down assembly includes a top plate, a bottom plate, and a compression assembly extending between the top and bottom plates. The compression assembly includes two, parallel biasing assemblies that extend along compression axes that are parallel to but offset from the central force axis. Each biasing assembly including an upper collar, a lower collar and a resilient biasing member, in one embodiment in the form of a coil spring, retained between the upper and lower collar. The parallel biasing assemblies are positioned on opposite sides from each other about the central force axis, and may be spaced away from the central force axis an equal distance.
