Apparatus for manufacture of vehicle wheels

Apparatus for forming at least one mounting opening in a vehicle wheel that includes a rim portion and a disc portion within said rim portion, said apparatus comprising:

• a circumferential series of locating means for engaging and locating the rim portion of a wheel,
• means reciprocable for forming at least one mounting opening on a first axis in the disc portion of a wheel engaged by said locating means,
• means for selectively moving said locating means between a first position and a second position radially inward of said first position in which said locating means engage and clamp the rim portion of a wheel positioned within said locating means, and
• ring means surrounding said first axis and operable to define with said moving means said second position of said locating means, said ring means being movable circumferentially of said first axis for adjusting said second position of all of said location means simultaneously,
• said ring means comprising an inner ring having a radially outwardly facing surface surrounding said first axis and itself having a central axis that is eccentric to said first axis, and an outer ring having a radially inwardly facing surface in engagement with said radially outwardly facing surface of said inner ring and a radially outwardly facing surface having a central axis that is eccentric to said central axis of said outer surface of said inner ring.

Apparatus for forming at least one mounting opening in a vehicle wheel that includes a rim portion and a disc portion within said rim portion, said apparatus comprising:

• a plurality of locating means disposed in a circumferential array for engaging the rim portion of a wheel within said locating means,
• means for forming at least one mounting opening on a first axis in the disc portion of a wheel engaged by said locating means,
• means for selectively moving said locating means into radial engagement with the rim portion of a wheel disposed within said locating means such that said locating means and said rim portion are positioned on a second axis, and
• means for adjustably positioning said second axis with respect to said first axis comprising a pair of radially internested rings, positioned for radial abutment with said moving means, a first of said rings having a radially outwardly facing surface at first eccentricity with respect to said first axis, a second of said rings having a radially inwardly facing surface operatively coupled to said radially outwardly facing surface of said first ring, and a radially outwardly facing surface at second eccentricity with respect to said radially inwardly facing surface of said second ring, orientation of said first and second eccentricities with respect to each other defining orientation of said second axis with respect to said first axis.

Apparatus for forming at least one mounting opening in a vehicle wheel that includes a rim portion and a disc portion within said rim portion, said apparatus comprising:

• a circumferential series of locating means for engaging and locating the rim portion of a wheel,
• means reciprocable for forming at least one mounting opening on a first axis in the disc portion of a wheel engaged by said locating means,
• means for selectively moving said locating means between a first position and a second position radially inward of said first position in which said locating means engage and clamp the rim portion of a wheel positioned within said locating means, and
• ring means surrounding said first axis and operable to define with said moving means said second position of said locating means, said ring means being movable circumferentially of said first axis for adjusting said second position of all of said location means simultaneously,
• said moving means including means for resiliently holding said moving means in abutting engagement with said ring means in said second position of said locating means.
