Abstract

Inventia se refera la un dispozitiv de rulat interior, destinat supranetezirii alezajelor, montat în axul principal al unei masini-unelte, de exemplu, o masina de gaurit. Dispozitivul de rulat interior, conform inventiei, este alcatuit dintr-o tija cu un con Morse, solidara cu un dorn tronconic ce antreneaza niste role aflate într-o colivie. Niste plunjere deplaseaza axial dornul tronconic printr-un inel de presiune, sub actiunea unei came frontale. Cama frontala este rotita de un levier si împinge niste tacheti fixati într-o bucsa, rigidizati cu un rulment axial. Levierul aluneca într-un slit al unui capac gradat, în vederea stabilirii pozitiei rolelor, functie de diametrul de lucru.The invention relates to an internal rolling device designed to overload boreholes mounted in the main shaft of a machine tool, for example, a drilling machine. The interior rolling device according to the invention consists of a rod with a Morse cone, integral with a frustoconical mandrel, which trains some rolls in a cage. Some plungers axially move the truncated mandrel through a pressure ring under the action of a front sprocket. The front cam is rotated by a lever and pushes some sticks fixed in a bush, stiffened with an axial ball bearing. The lever slides into a slit of a graduated cover to determine the position of the rollers, depending on the diameter of the workpiece.
