ABSTRACT:
An improved coupling system for lockably coupling machine tool components is provided that includes a male coupling, a female coupling having an axis, a pair of opposing jaw members having lock surfaces for engaging ledge surfaces in the male coupling when the jaw members are moved apart, and a drive train having first and second drive spheres for simultaneously moving proximal and distal ends of the jaw members apart. The drive spheres engage ramps on the inner surfaces of the jaw members that have cylindrical profiles to provide lenticular contact between the spheres and the jaw members. Cam and follower surfaces are provided between the jaw members and one of the male or female couplings to enhance the locking force between the couplings. The invention provides a more rigid coupling between the male and female components by providing two locking spheres that operate in tandem to simultaneously spread the distal and proximal ends of the jaw members apart.
