METHOD FOR ASSEMBLING THREADED JOINTS Russian patent published in 2004 - IPC

FIELD: machine engineering, possibly assembling threaded joints. SUBSTANCE: method for assembling threaded joints comprises steps of squeezing joined parts; screwing-on movable member onto stationary member of threaded joint; preliminarily tightening joint due to action of forced oscillations upon threaded joint; finally tightening joint and performing quality control of tightened joint; additionally changing frequency of forced oscillations for achieving resonance; converting mechanical oscillations to electric signal; registering Q-value as quality parameter at process of forming joint; realizing final tightening at time moment of squeezing joined parts until achieving reference Q-value. EFFECT: enhanced quality of threaded joints. 1 dwg
