Abstract
An axial displacement mechanism for precisely adjusting the axial displacement of a turret plate relative to a turret table is disclosed. Turret tables are commonly used to support a workpiece such as the hollow tubular section of a tin box immediately prior to the seaming of a lid thereto and are commonly angularly indexed between a plurality, usually four, separate work stations disposed above the turret plate. The turret table is rigidly secured to a frame while the turret plate must be capable of being axially displaced relative thereto to suit a variety of different components. The turret plate is rigidly secured to an annular bush through a central aperture of which passes a cylindrical screw, the threads of which engage in corresponding threads in the inner annular surface of the bush. The screw abuts an axially fixed portion secured to or being a drive spindle which imparts motion to said fixed portion, said annular bush and said screw to cause the turret plate to rotate. The provision of threads on the outside of the cylindrical screw and the abutment thereof with the spindle or fixed portion ensures that the rotation of the screw causes axial displacement of the annular b…
