DISPOSITIVO PER FISSARE L'ARMATURA SULL'ANELLO REGOLATORE DI UN FRANTOIO A CONO

The ring lock cooperates with a threaded supporting ring and consists of a lock nut and hydraulic cylinders whose spring loaded rods terminate in a slot, whose one surface is formed by the taper of the nut. For an effective locking action, which is simple to perform and resists service loading, the cylinder (7) rods (6) are radial to the nut (4) axis and the taper (5) on this faces outwards so that the slot (9) is completed by the end face (10) of the supporting ring (1). The nut may be screwed onto the adjuster ring (3). Preferably the nut meets the support ring (1) over a cylindrical interface (18) and is locked (19) in relation to this. The cylinders may be mounted on the support ring and the rod tips (8) may adjust vertically relative to the rods. This prevents misalignment of the threads, extends cylinder life, as the current ring is seldom removed, and protects the rods from deformation.
