Abstract
A clamping assembly includes a collet adapter and an expansion sleeve movably disposed in collet adapter and a draw pin movably disposed in the expansion sleeve. The expansion sleeve cooperates with the draw pin to define a containment system configured maintain the expansion sleeve within an axial envelope and a radial envelope within the collet adapter. Axial movement of the draw pin in the expansion sleeve within the axial envelope causes a portion of the expansion sleeve to expand radially outward to a predetermined maximum diameter to releasably clamp the collet in the collet adapter.
