Abstract

Disclosed in this document is a method of clamping a workpiece or stack of workpieces to a table or fixture. The Quick Clamp allows the workpiece or stack of material to be fixed to the worktable with a minimum of the clamp extending above the work surface. This design has the advantage of being a low profile apparatus that can be used on devices such as CNC machine tools to clamp the workpiece while minimizing the possibility of interference between the machine tool and clamping device. A diagram of the Quick Clamp is shown in the Figure.

Quick Clamp

      Disclosed in this document is a method of clamping a workpiece
or stack of workpieces to a table or fixture.  The Quick Clamp allows
the workpiece or stack of material to be fixed to the worktable with
a minimum of the clamp extending above the work surface.  This design
has the advantage of being a low profile apparatus that can be used
on devices such as CNC machine tools to clamp the workpiece while
minimizing the possibility of interference between the machine tool
and clamping device.  A diagram of the Quick Clamp is shown in the
Figure.

      The operation of the device is simple and exact.  The base 4 is
mounted to the work surface by fasteners placed through the two
mounting holes.  The clamp is opened by lifting the Clamp Lever 2.
This lifting motion permits the Pivot Clamp 1 to rotate up and off of
the workpiece being clamped.  Once a new workpiece is in place, the

Clamp Lever 2 is pushed down.  The pressure of the Clamp Lever 2
against the Spring Plate 5 causes the Pivot Clamp 1 to be forced down
against the workpiece.  Once the clamp is fully closed, the Clamp
Lever 2 comes to rest in a detent in the Spring Plate 5.  This holds
the Quick CLamp in a closed position until the Clamp Lever 2 is
lifted again to insert a new workpiece.
