ALIGNMENT OF THE PARTS USING HIGH FREQUENCY VIBRATIONS

In this paper experimentally analyzed mutual part alignment using elastic vibrations in automated assembly. The peg fixed in a gripper and elastic vibrations excited in longitudinal direction by mean of the pressed piezoelectric vibrator. The end tip of the peg vibrates in longitudinal and lateral directions in the contact point with the bush. It forces to move bush respectively to peg along the part alignment direction. Experimental setup and methodology explained. Influence of axis misalignment, initial pressing force and excitation frequency/amplitude to the stable and reliable alignment duration using parts from different materials with different shape/size has been determined
