Water jet strengthening and polishing integrated system and method for blades of blisk

A water jet strengthening and polishing integrated system for blades of a blisk, comprising a vibration polishing unit and a water jet strengthening unit, wherein

• the vibration polishing unit comprises 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;
• the vibration polishing unit further comprises at least three support springs, top ends of the support springs are fixedly connected with the vibration polishing bath, and bottom ends of the support springs are fixedly connected with a workbench;
• and
• the water jet strengthening unit comprises 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;
• wherein the water jet strengthening device comprises a high-pressure water inlet pipe, a diverter valve and an abrasive-particle-mixed connecting valve, two abrasive particle mixing cavities which are isolated from each other are formed in the abrasive-particle-mixed connecting valve, one end of the high-pressure water inlet pipe and one end of each abrasive particle mixing cavity communicate with the diverter valve, each abrasive particle mixing cavity communicates with an abrasive particle inlet, and one end, away from a corresponding abrasive particle mixing cavity, of each abrasive particle inlet is connected with an abrasive particle feed pipe;
• and
• an other end of each abrasive particle mixing cavity is fixedly connected with a jet pipe, one end, away from the abrasive particle mixing cavity, of the jet pipe is provided with a jet nozzle, the jet nozzle on one jet pipe corresponds to the jet nozzle on another jet pipe, and two corresponding jet nozzles are oppositely arranged;
• wherein the two abrasive particle mixing cavities are formed in the abrasive-particle-mixed connecting valve, and the diverter valve is a three-way diverter valve;
• and each abrasive particle mixing cavity communicates with the diverter valve through a high-pressure diverter pipe.
