CORE SHAFT CENTERING MECHANISM AT HARDENING OF ADHESIVE

PURPOSE:To execute accurate centering and sure pressing only by one driving operation and to reduce the cost of the titled mechanism by loosely engaging a push bar whose tip is formed like a sphere with a press for a material to be worked and providing a centering fitting slidably thereto. CONSTITUTION:The press 6 for a material to be worked is loosely engaged with the push bar 1 whose tip is formed like a sphere and the centering fitting 5 capable of sliding in the axial direction of the press 6 and having a prescribed inclined surface to be excited by a compression spring 4 is engaged with the press 6 to constitute a floating mechanism. When a lower drum 8 to be the material to be worked is to be stuck to the core 7, the press 6 is descended to pick up the center of the lower drum 8 at first. Then, the centering of the lower drum 8 and the core 7 is executed by the formed of the spring 4 and the press 6 is descended furthermore to press and stick the core 7 to the lower drum 8. Consequently, accurate centering and sure press adhesion can be executed only by one driving operation and the cost can be reduced.
