Three-piece clamping assembly

Abstract

A clamping assembly including a first end member having a recess defined in an end surface thereof and a bore between opposing end surfaces thereof. An intermediate member has a recess in each end surface thereof and a bore between the first and second end surfaces thereof. A second end member has first and second end surfaces and a recess defined in one of the end surfaces thereof, and a threaded bore between the first and second end surfaces. The intermediate member is disposed between the first and second end members such that the threaded bore aligns with the bore of the intermediate member and the bore of the first end member. One recess of the intermediate member cooperates with the recess of the first end member to define a first pin bore through the clamping assembly. The other recess of the intermediate member cooperates with the recess of the second end member to define a second pin bore through the clamping assembly disposed generally transverse to the first pin bore. A threaded rod is disposed through the bore of the intermediate member and the bore of the first end member and is in threaded engagement with the threads defined in the bore of the second end member at one end thereof. A control knob is engaged to the threaded rod at the other end thereof such that once the control knob is moved to further engage the threaded rod with the screw threads of the bore, surfaces defining the first and second pin bores frictionally engage and clamp an associated pins therein.
