Abstract

A spacer assembly and method for using same to fix a first component to a second component are provided. The method includes positioning the first and second spacer segments between the first and second components, the first and second spacer segments each including an inner face, an opposite outer face, and an exterior surface extending along a longitudinal axis between the inner face and the outer face. The exterior surfaces of the first and second spacer segments are coaxially aligned and secured by a securing device such that the inner faces of the first and second spacer segments define supplementary non-perpendicular angles relative to the longitudinal axis and the outer faces of the first and second spacer segments are parallel to one another. The securing device and the first and second spacer segments are removed after the first component is mechanically coupled to the second component.

First claim

What is claimed is:

1 . A method for fixing a first component relative to a second component, the method comprising:
positioning a first spacer segment and a second spacer segment between the first component and the second component, the first spacer segment and the second spacer segment each comprising an inner face, an opposite outer face, and an alignment bore extending along a longitudinal axis from the inner face to the outer face, the inner face being oriented at an angle relative to the outer face; coaxially aligning the alignment bore of the first spacer segment and the alignment bore of the second spacer segment with an aperture in the first component and an aperture in the second component such that the inner faces of the first and second spacer segments define supplementary non-perpendicular angles relative to the longitudinal axis of the alignment bore and the outer faces of the first and second spacer segments are parallel to one another; extending a securement pin through the aperture of the first component, the alignment bore of the first spacer segment, the alignment bore of the second spacer segment, and the aperture of the second component; mechanically coupling the first component to the second component; and removing the securement pin, the first spacer segment, and the second spacer segment from between the first component and the second component.

2 . The method of claim 1 , wherein removing the securement pin, the first spacer segment, and the second spacer segment comprises removing the securement pin prior to removing the first spacer segment and the second spacer segment.

3 . The method of claim 2 , wherein removing the first spacer segment and the second spacer segment comprises moving the first spacer segment in a first direction and moving the second spacer segment in second direction opposite the first direction.

4 . The method of claim 3 , wherein the first direction is parallel to the outer face of the first spacer segment and the second direction is parallel to the outer face of the second spacer segment.

5 . The method of claim 1 , wherein the alignment bore of the first spacer segment and the alignment bore of the second spacer segment define circular cross-sections of equal dimensions.

6 . The method of claim 1 , wherein the aperture in the first component and the aperture in the second component are aligned along the longitudinal axis and configured to receive a common axle.

7 . The method of claim 6 , further comprising inserting the common axle after removing the securement pin, the first spacer segment, and the second spacer segment from between the first component and the second component.

8 . The method of claim 1 , wherein:
the first component comprises a first part and a second part coupled to the first part, the first part of the first component comprises the aperture of the first component; the second component comprises a first part and a second part coupled to the first part, the first part of the second component comprises the aperture of the second component; and the second part of the first component is mechanically coupled to the second part of the second component.

9 . The method of claim 1 , wherein:
an inner surface of the first component is oriented parallel to and faces an inner surface of the second component; the outer face of the first spacer segment contacts the inner surface of the first component; and the outer face of the second spacer segment contacts the inner surface of the second component.

10 . The method of claim 1 , wherein the securement pin comprises a first end and an opposite second end, a stopper is formed at the first end having a diameter greater than a diameter of the first end to prevent extension of the stopper through the aperture of the first component or the aperture of the second component.

11 . The method of claim 10 , further comprising:
inserting a ball detent pin through an aperture formed proximate the second end of the securement pin and extending in a direction perpendicular to a longitudinal axis of the securement pin after the securement pin is extended through the aperture of the first component, the alignment bore of the first spacer segment, the alignment bore of the second spacer segment, and the aperture of the second component, wherein the ball detent pin prevents removal of the securement pin from the first component, the first spacer segment, the second spacer segment, and the second component.

12 . The method of claim 1 , further comprising positioning a key extending from the inner face of the first spacer segment into a recess formed in the inner face of the second spacer segment.

13 . The method of claim 1 , wherein the first spacer segment has a length extending in the longitudinal axis and the second spacer segment has a length extending in the longitudinal axis, the length of the first spacer segment being the same as the length of the second spacer segment.

14 . The method of claim 13 , wherein the length of the first spacer segment and the length of the second spacer segment are 4 inches.

15 . The method of claim 13 , wherein the length of the first spacer segment and the length of the second spacer segment are 5 inches.

16 . The method of claim 1 wherein the angle between the inner face and the outer face of the first spacer segment and the angle between the inner face and the outer face of the second spacer segment are the same, the angles being between 30 degrees and 60 degrees.

17 . The method of claim 1 , wherein the first spacer segment and the second spacer segment each comprise one or more grooves or protrusions formed on an exterior surface thereof, extending along the longitudinal axis, and coaxial with one another.

18 . A method for fixing a first component relative to a second component, the method comprising:
positioning a first spacer segment and a second spacer segment between the first component and the second component, the first spacer segment and the second spacer segment each comprising an inner face, an opposite outer face, and an exterior surface extending along a longitudinal axis between the inner face and the outer face, the inner face being oriented at an angle relative to the outer face; coaxially aligning the exterior surfaces of the first spacer segment and the second spacer segment such that the inner faces of the first and second spacer segments define supplementary non-perpendicular angles relative to the longitudinal axis and the outer faces of the first and second spacer segments are parallel to one another; positioning a V-block clamp relative to the first component and the second component to fix the first spacer segment relative to the second spacer segment; mechanically coupling the first component to the second component; and removing the V-block clamp, the first spacer segment, and the second spacer segment from between the first component and the second component.

19 . The method of claim 18 , wherein the V-block clamp comprises:
a body positioned against a first side of the exterior surfaces of the first spacer segment and the second spacer segment; one or more arms extending from the body; and an adjustable screw member extending through the one or more arms to contact a second side of the exterior surfaces of the first spacer segment and the second spacer segment opposite the first side to maintain coaxial alignment of the first spacer segment and the second spacer segment.

20 . A spacer assembly comprisin
