Interchangeable locating pin assembly for locating manufactured parts

An interchangeable locating pin assembly for locating a manufactured part comprising:

• a) a locating pin housing having a body, the body having
• i) a hollow interior portion,
• ii) an open upper end,
• iii) a substantially closed lower end having a bottom plug integrally formed therewith, and
• iv) a wall having a uniform thickness disposed between the upper open end and the lower end, the wall having
• A) an outer portion, and
• B) an inner portion, the body further having
• v) an anti-rotate stop pin protruding inwardly from the inner portion of the wall towards the hollow interior portion of the housing;
• b) a flange for locating the manufactured part;
• c) a locating pin having
• i) a tapered head for engaging the manufactured part at a single contact point, and
• ii) a shank, the shank is complementary in shape to the interior portion of the housing body for slidably engaging the interior portion of the housing body, and is disposed in axial alignment with the tapered head extending axially downwardly from the tapered head, the shank further having
• A) a uniform transverse cross section,
• B) an upper planar end juxtaposed beneath the base portion of the tapered head wherein the second peripheral edge of the tapered head further defines a perimeter of the upper planar end,
• C) a lower planar end,
• D) a uniform peripheral wall extending between the upper planar end and the lower planar end, and
• E) a slot formed within the uniform peripheral wall, a longitudinal slot disposed through the uniform peripheral wall of the shank for allowing travel of the locating pin relative to the housing, the slot having a top shelf flush with the upper planar end of the shank, and a bottom shelf extending downwardly from the top shelf, wherein the anti-rotate stop pin slidably engages the slot between the top shelf and the bottom shelf, the anti-rotate stop pin fixedly attached to the locating body housing at a distance below the flange equal to a distance greater than an axial longitudinal length of the tapered head, and wherein the slot and the anti-rotate stop pin cooperate to move the locating pin relative to the housing between a first extended position, a second partially retracted position, and a third fully retracted position;
• and
• d) means for preventing movement of the pin relative to the housing.

• c) a locating pin having
• i) a tapered head for engaging the manufactured part at a single contact point, the tapered head having
• A) a top planar surface having a first peripheral edge defining a perimeter of the top planar surface,
• B) a base portion having a second peripheral edge defining a perimeter of the base portion, wherein the first peripheral edge perimeter is less than the second peripheral edge perimeter, and
• C) a tapered peripheral wall extending outwardly and sloping downwardly at an angle from the top planar surface, the tapered peripheral wall is further disposed between the first peripheral edge and the second peripheral edge, wherein the wall is narrower near the first peripheral edge and is wider near the second peripheral edge, and
• ii) a shank complementary in shape to the interior portion of the housing body for slidably engaging the interior portion of the housing body, the shank disposed in axial alignment with the tapered head extending axially downwardly from the tapered head having
• A) a recess formed within the peripheral wall of the shank, and
• B) a removable set screw disposed within the recess, wherein the set screw engages the slot in the body and cooperates with the slot to control travel of the locating pin relative to the housing by axially moving the locating pin relative to the housing between a first extended position, a second partially retracted intermediary position, and a third fully retracted position;
• and
• d) a compression spring disposed between the a bottom plug and the shank for preventing movement of the pin relative to the housing.
