Abstract:
A pressure clamp assembly for clamping a plurality of overlapping members together and for facilitating accurate drilling of the overlapping members using a drill and a drill bit assembly, the pressure clamp assembly comprising:a clamp body; a first compression member having an elongated foot shape opposingly spaced from a second compression member and defining a gap, the compression members attached to the clamp body, at least one of the compression members movable toward the other one of the compression members, and at least the first compression member defining at least one drill bit assembly guide having an opening configured to receive and guide the drill bit assembly of the drill, said opening having an off-center positioning on the elongated foot; and a power source operable to drive the at least one movable compression member so as to shrink the gap and clampingly engage the plurality of overlapping members between the compression members with sufficient pressure to resist interlaminate burring during operation of the drill.
