Mechanical parts assembling and centering device, has tapped bushing having threaded centering part containing expansion slits so that rod can be slidingly assembled and disassembled in bores of mechanical parts when screw is loosened

摘要

The device has a tapped bushing (1) for receiving a screw (13) and comprising a head and a shaft with a threaded centering part (4) containing at least one expansion slit. The slits allow sliding assembly and disassembly of the bushing in the corresponding bores of the mechanical parts (10, 11) when the screw is loosened. The slits allow radial expansion of the centering part when the screw is passed through the centering part.
