Abstract

The utility model relates to a six degrees of freedom vibratory stress relief device which comprises six vibration excitation branch chains, a moving platform and a rack. The upper ends of the six vibration excitation branch chains are connected with the moving platform through a second spherical pair, a forth spherical pair, a sixth spherical pair, an eighth spherical pair, a tenth spherical pair and a twelfth spherical pair. The lower ends of the six vibration excitation branch chains are connected with the rack through a first spherical pair, a third spherical pair, a fifth spherical pair, a seventh spherical pair, a ninth spherical pair and an eleventh spherical pair. The moving platform is used for installing various workpieces to perform vibratory stress relief processing. The joint vibration excitation of six vibration exciters enables the moving platform to perform six degrees of freedom space vibration so that the workpieces are excited to produce various frequencies and resonance of various modes of vibration which include nonlinear vibration, such as combination resonance, subharmonic resonance, multiple resonance and the like, thereby ensuring every position in the workpieces to produce enough stress and strain, effectively eliminating residual stress of the workpieces and remarkably improving effect of the vibratory stress relief.
