[0002] Vibration aging treatment is a commonly used method for eliminating residual internal stress in engineering materials. The essence of vibration aging is to apply a dynamic stress to the workpiece in the form of vibration. When the dynamic stress is superimposed on the residual stress of the workpiece itself and reaches or exceeds the micro yield limit of the material, the workpiece will undergo microscopic or macroscopic local or overall elastic-plastic deformation, while reducing and homogenizing the residual stress inside the workpiece, ultimately achieving the purpose of preventing deformation and cracking of the workpiece and stabilizing the size and geometric accuracy of the workpiece.

[0003] Vibrator is the excitation source of various vibration machinery, and is widely used in vibrating feeders, vibrating conveyors, vibrating dryers, vibrating ore dressing machines, vibrating sand shakers, vibrating section dividers and vibrating anti-blocking machines for silos in industries such as electricity, building materials, grain, coal, mining, metallurgy, chemical industry, light industry, casting, railways, cement, and ports.

However, one clamping can only vibrate in one dimension, and the aging effect is not ideal.

The utility model multi-dimensional stress relief device adopts a rotary eccentric structure different from the traditional mechanical vibrator, and adopts a linear motor vibration source, which can provide limited exciting force, and the utility model patent is only for the field of vibration aging stress relief of workpieces. This device only solves the problem of vibration aging of small and medium-sized parts. At the same time, the device only vibrates in two dimensions.
