Abstract

Inventia se refera la un dispozitiv rotitor de prindere si antrenare, cu trecere larga, folosit pentru antrenarea în miscare de rotatie a semifabricatelor de lungime mare si diametru variabil în procesele tehnologice de prelucrare prin aschiere, sudare etc, actionat pneumatic sau hidraulic. Dispozitivul, conform inventiei este alcatuit dintr-un corp de antrenare ce poarta un inel de strangere cu trei locase excentrice. Prinderea semifabricatului se face cu bacuri de prindere. Rotirea corpului deantrenare se realizeaza prin intermediul unui arbore si al unui angrenaj cilindric. Inelul de strangere este actionat într-o miscare de rotatie suplimentara de un cilindru de forta care prin intermediul unei cremaliere antreneaza o coroana dintata p rinsa rigid carcasa unui diferential, ce printr-un lant cinematic transmite miscarea unei coroane dintate fixate pe inelul de strangere.The invention relates to a wide gripping and traversing rotating device used for rotation of large length semifinished products and variable diameter in the technological processes of cutting, welding, etc., pneumatically or hydraulically operated. The device according to the invention consists of a drive body bearing a clamping ring with three eccentric locations. The fastening of the blank is done with clamping jaws. The rotation of the de-winding body is achieved by means of a shaft and a cylindrical gear. The clamping ring is actuated in a further rotation movement by a force cylinder which, by means of a rack, drives a rigid toothed crown of a differential housing, which, through a kinematic chain, conveys the movement of a toothed ring fixed to the clamping ring.
