Abstract
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 workholding clamp for securing a workpiece to a work surface, the workholding clamp comprising:
- 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 comprising:
- a fixed body secured to a T-slot in the work surface and providing a jaw receiving cradle with a fastener receiving hole and having a curved backstop wall surface;
- a pivoting jaw pivotably received within the jaw receiving cradle, and having a clamp edge provided with a plurality of serrations, a fastener receiving through hole, and a complex radius surface located opposite the clamp edge;
- and
- a clamping fastener aligned transverse to the work surface, and directed to pass through the fastener receiving through hole, and tightened to cause the pivoting jaw to pivot in a direction along a first axis in line with the clamping fastener.
A workstop for reliably locating a workpiece relative to a work surface comprising:
- a body having a right cylindrical upper portion, and a lower portion having a first profile in a first rotation state presenting a rectangular profile configured to fit vertically into a T-slot, and upon rotation of the work stop to a second rotation state, the lower portion presenting a non-rectangular second profile that conforms to the T-slot, so as to restrain the body within the T-slot while rotated;
- and
- at least one fastener residing at least partially within the body, and to be rotated to draw the fastener downwards and thereby secure the workstop within the-slot.
