Vibration aging device

The utility model relates to the technical field of vibration aging and provides a vibration aging device which adopts a contact terminal to instantly hit a welding piece to realize seam vibration aging of the welding piece. The vibration aging device mainly comprises a contact terminal for hit aging of a welding piece, a trace wheel used for controlling the frequency in hitting the welding piece by the contact terminal and a V-shaped worktable used for supporting the welding piece. A driving motor conveys rotary motion to the trace wheel, a connecting bar moves along the internal trace of the trace wheel through a roller, the rotary motion of the trace wheel is converted into linear motion of the connecting bar, and the connecting bar indirectly drives the contact terminal to instantly hit the welding piece. The defects that manually eliminating the residual stress of a seam is time-consuming and toilsome, and the hitting frequency is low are avoided, the working efficiency is greatly improved, and the present demand for eliminating mass welding residual stress is satisfied.
