A build plate-clamping assembly may include a work station having a build plate-receiving surface and a lock-pin extending from the build plate-receiving surface of the work station. The lock-pin may include a hollow pin body, a piston disposed within the hollow pin body, with the piston axially movable from a retracted position to an actuated position, and a plurality of detents, with the plurality of detents radially extensible through respective ones of a plurality of detent-apertures in the hollow pin body responsive to the piston having been axially moved to the actuated position. A methods of working on workpieces may include lockingly engaging a build plate at a first work station, performing a first work-step, releasing the build plate from the first work station, lockingly engaging the build plate at a second work station, and performing a second work-step. An additive manufacturing system may include a vision system with a first build plate-receiving surface and an additive manufacturing machine with a second build plate-receiving surface.

A device for clamping a piece of formwork includes a bar having an end for attachment to a body. The device includes a jaw mounted on the bar and for receiving the piece of formwork, the jaw being movable along the bar.

Jigs and fixtures for aligning, guiding, and/or holding a workpiece on woodworking machinery during a woodworking operation are described, as well as methods of making, modifying, and using jigs and fixtures.

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.

A method of installing a plurality of nut and bolt fasteners upon a structure is disclosed. The method includes placing a jig around the nut of a first fastener and the nut of a second fastener, securing the jig to the first fastener, and then using a power tool to tighten the nut of the second fastener to a target torque. The step of tightening the nut comprises engaging a socket portion of the power tool with the nut, securing the power tool to the jig such that a handle portion of the power tool is prevented from rotating about an axis of rotation of a socket portion of the power tool when the nut is being rotated by the socket portion. A jig, jig fasteners for securing a jig to a fastener, and a fastening head for a power tool are disclosed.

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.

An attachment jig includes a pressing member having a positioning portion configured to position a target component in a direction where an attachment target surface of a fixing target member extends, and a pressing portion configured to press the target component positioned by the positioning portion toward the attachment target surface, and a detachment member having a first abutting portion configured to come into contact with the attachment target surface, the first support surface, and the second support surface, and a second abutting portion configured to come into contact with the pressing member on the attachment target surface, is the detachment member being configured to cause the pressing member to be positioned in a direction where the attachment target surface extends with respect to the first support surface and the second support surface, and detachable from the pressing member.

A receiving device for receiving an object of any shape includes a horizontally extending base plate with a plurality of threaded bores being defined in the base plate, where the plurality of threaded bores are spaced apart across the base plate. The receiving device further includes a plurality of supports, where each of the plurality of supports extends between a first end and a second end. Each of the plurality of supports is screwed proximate the first end into the plurality of threaded bores such that the second ends of the plurality of supports project vertically upward at a specific height from the base plate such that an object of any shape is placeable in a desired position on the second ends of the plurality of supports.

A hybrid clamp is configurable as a bar clamp or a dog clamp, where first and second clamp members may be associated with a clamp bar or may be separated and connected to other supports for use as dog clamps. A clamping sawhorse is configured to mount the hybrid clamp for use as a bar clamp or as a dog clamp in conjunction with the sawhorse, such as including apertures for accepting either the clamp bar or mounting portions of the first and second clamps.

A clamp comprises first and second clamp halves, each comprising an elongate object receiving portion and a portion of a clamp retention mechanism. The first and second elongate object receiving portions are sized and shaped to cooperatively hold an elongate object at a desired position when the first and second clamp halves are fastened together. The first and second portions of the clamp retention mechanism are sized and shaped to (a) engage each other when the first and second clamp halves are moved towards each other in a first direction, (b) fasten the first and second clamp halves together without requiring use of a tool to engage the retention mechanism, and (c) disengage from each other when the first and second clamp halves are moved away from each other in a direction orthogonal to the first direction to unfasten the first and second clamp halves without use of a tool.
