Abstract:
An axial displacement mechanism for a turret plate rotationally driven by a spindle to which said mechanism is rigidly secured or with which said mechanism is integral, said mechanism comprising an axially fixed portion and a movable portion capable of being moved axially relative to the fixed portion, said axially fixed and axially movable portions being rotated simultaneously when the spindle is drivingly actuated in use, said fixed portion comprising location means which are received in the movable portion, wherein said location means prevent said movable portion from rotating relative to the fixed portion and wherein the mechanism further comprises screw means separate from said location means, said screw means being provided with threads which engage corresponding threads in the axially movable portion such that rotation of the screw means causes axial displacement of the axially movable portion relative to the axially fixed portion on the location means to permit adjustment when the spindle is stationary.
