| 2000 | Invention patented by Collin Nicholas McConnell on May 26th, 2000. 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 bush and thus the turret plate relative to the turret table while the screw remains axially static. Guide mechanisms in the form of cylindrical pegs provided in the axially fixed portion are received through apertures in the annular bush to guide same and prevent angular displacement thereof as it is axially displaced. Locking mechanisms are provided to lock the screw to the spindle or other fixed portion to prevent unwanted rotation of same during rotation of the turret plate. |
