Abstract

Inventia se refera la o mandrina de filetat utilizata la executarea operatiei de filetare a gaurilor strapunse sau înfundate, pentru filete pe stînga sau pe dreapta. Problema pe care o rezolva inventia este realizarea unei mandrine pentru filetare mecanica cu moment reglabil, cu compensare axiala si reversibilitatea miscarii de rotatie a sculei. Inventia, în scopul obtinerii cuplului reglabil de filetare, foloseste un sistem simplificat, format dintr-un capac gradat, pe filet, ce actioneaza un cuplaj cu bile si arcuri, care transmite miscarea la un tambur central pozitionat în axa masinii-unelte, care prin intermediul altor bile de cuplare transmite miscarea la un ax solidar cu sistemul de prindere a sculei, compensarea axiala în mandrina realizîndu-se prin deplasarea axului solidar la scula, prin culisare într-un tambur central, fiind mentinut în pozitie initiala de un sistem de arcuri compensatoare, dispuse simetric în axa mandrinei. The invention relates to a threaded chuck used to perform the threaded or clogged holes for threading to the left or right. The problem solved by the invention is to provide a mechanical threading mandrel with adjustable torque, axial compensation and reversibility of the tool rotation movement. The invention, in order to obtain the adjustable threaded torque, uses a simplified system consisting of a graduated threaded cap which acts as a ball and spring coupling which conveys the movement to a central drum positioned in the axis of the machine tool, through other coupling balls transmits the movement to a shaft integral with the tool clamping system, the axial compensation in the mandrel being realized by moving the solid shaft to the tool by sliding in a central drum, being maintained in the initial position by a spring system compensating devices arranged symmetrically in the mandrel axis.
