Abstract
A tool turret has a brake to retain the turret in an an index position. The brake has stationary and rotatable brake members, each formed with a cone-shaped braking surface and a radial or face braking surface. A tooling plate carries a plurality of cutting tools and is mounted on the rotatable brake member. When the brake members are moved toward one another, the cone-shaped braking surfaces engage and the face braking surfaces engage in an indexed position in which one of the cutting tools is brought into a position for engaging a workpiece. When the brake members are disengaged, a motor turns the rotatable brake member and the tooling plate to another indexed position. The cone-shaped braking surfaces are mounted on flexibly resilient braking elements of the brake members to enable them to flex upon initial engagement of the cone-shaped braking surfaces, so that further movement of the brake members towards one another into full engagement with the face braking surfaces is permitted. The brake member on which the tooling plate is mounted is attached to the motor rotor by a flexible section, and the stator of the motor is mounted on a flex plate to enable axial float of the motor and to compensate for any lateral or angular misalignment of the motor and brake, so that full braking engagement can be achieved.
