Abstract

A water jet strengthening and polishing integrated system for blades of a blisk includes a vibration polishing unit and a water jet strengthening unit. The vibration polishing unit includes a vibration polishing bath, the vibration polishing bath is internally provided with a clamp for clamping the blisk, and vibration motors for driving the vibration polishing bath to vibrate are installed on the vibration polishing bath. Top ends of support springs are fixedly connected with the vibration polishing bath, and bottom ends of the support springs are fixedly connected with a workbench. The water jet strengthening unit includes a water jet strengthening device for carrying out water jet strengthening on the blades of the blisk and a driving mechanism for clamping the water jet strengthening device and capable of driving the water jet strengthening device to move in any direction in space.
