Abstract

A modular angular alignment clocking mechanism employs a hollow housing, a threaded interface ring, and a compression spring. The threaded interface ring is inserted into the housing and is followed by the compression spring. The housing is configured to thread onto one cylinder. Another cylinder is then threaded into the threaded interface ring and torqued to specification after clocking.

First claim

What is claimed is:

1. A modular angular alignment clocking mechanism, comprising:
a hollow housing having a first end, a second end, an interior surface, an exterior surface, a cylinder wall defined by said interior surface and said exterior surface, and a central longitudinal axis spanning from said first end to said second end of said hollow housing, said cylinder wall having a motion stop on said interior surface at said first end, said interior surface of said hollow housing having an interior threaded portion at said second end;
at least one longitudinal aperture in said cylinder wall, said at least one longitudinal aperture oriented parallel with said central longitudinal axis and positioned at said first end of said hollow housing, said at least one longitudinal aperture transitioning to a terminal slot in said cylinder wall;
a threaded interface ring configured for removable insertion longitudinally into said second end of said hollow housing, wherein said interior surface of said hollow housing circumscribes said threaded interface ring;
a compression spring configured for removable insertion longitudinally into said second end of said hollow housing and juxtaposed against said threaded interface ring, wherein said interior surface of said hollow housing circumscribes said compression spring;
wherein said threaded interface ring, comprising:
a threaded inner surface and an outer surface;
a plurality of clocking teeth etched into said outer surface;
wherein said plurality of clocking teeth are axially spaced at equal distance along said outer surface, said spacing at a range of about 2 to 10 degrees;
said threaded interface ring positioned between said compression spring and said motion stop; and

at least one dowel pin compression fit in said at least one longitudinal aperture.

2. The mechanism according to claim 1 , said compression spring having an axial spring force range of about 5 pounds to about 14 pounds, as measured longitudinally along said central longitudinal axis.

3. The mechanism according to claim 1 , said compression spring having a maximum axial spring force of about 14 pounds, as measured longitudinally along said central longitudinal axis.

4. The mechanism according to claim 1 , further comprising a viewing area in said exterior surface of said hollow housing, said viewing area configured for determining angular measurements corresponding to said axial spacing of said plurality of clocking teeth.

5. The mechanism according to claim 4 , wherein said viewing area is a window.

6. The mechanism according to claim 4 , wherein said viewing area is a recessed area.

7. A modular angular alignment clocking mechanism assembly, comprising:
a hollow housing having a first end, a second end, an interior surface, an exterior surface, a cylinder wall defined by said interior surface and said exterior surface, and a central longitudinal axis spanning from said first end to said second end of said hollow housing, said cylinder wall having a motion stop on said interior surface at said first end, said interior surface of said hollow housing having an interior threaded portion at said second end;
at least one longitudinal aperture in said cylinder wall, said at least one longitudinal aperture oriented parallel with said central longitudinal axis and positioned at said first end of said hollow housing, said at least one longitudinal aperture transitioning to a terminal slot in said cylinder wall;
a threaded interface ring configured for removable insertion longitudinally into said second end of said hollow housing, wherein said interior surface of said hollow housing circumscribes said threaded interface ring;
a compression spring configured for removable insertion longitudinally into said second end of said hollow housing and juxtaposed against said threaded interface ring, wherein said interior surface of said hollow housing circumscribes said compression spring;
at least one dowel pin compression fit in said at least one longitudinal aperture;
a first cylinder having an proximal end, a distal end, and a threaded outer surface portion on said proximal end of said first cylinder, said threaded outer surface portion on said proximal end of said first cylinder configured to engage with said interior threaded portion of said hollow housing;
wherein said threaded interface ring, comprising:
a threaded inner surface and an outer surface;
a plurality of clocking teeth etched into said outer surface;
wherein said plurality of clocking teeth are axially spaced at equal distance along said outer surface, said spacing at a range of about 2 to 10 degrees;
said threaded interface ring positioned between said compression spring and said motion stop; and

a second cylinder having an proximal end and a distal end, and a threaded outer surface portion on said proximal end of said second cylinder, said threaded outer surface portion on said proximal end of said second cylinder configured to engage with said threaded inner surface of said threaded interface ring.

8. The mechanism according to claim 7 , said compression spring having an axial spring force range of about 5 pounds to about 14 pounds, as measured longitudinally along said central longitudinal axis.

9. The mechanism according to claim 7 , said compression spring having a maximum axial spring force of about 14 pounds, as measured longitudinally along said central longitudinal axis.

10. The mechanism according to claim 7 , further comprising a viewing area in said exterior surface of said hollow housing, said viewing area configured for determining angular measurements corresponding to an angular reference of said first cylinder compared to said second cylinder.

11. The mechanism according to claim 10 , wherein said viewing area is a window.

12. The mechanism according to claim 10 , wherein said viewing area is a recessed area.
