RECIPROCATING ABRASIVE FLOW POLISHING DEVICE BASED ON CAVITATION EFFECT, AND METHOD

WIPO Patent Application WO/2024/001389

A1

A reciprocating abrasive flow polishing device based on a cavitation effect. A lower sealing plate (3) is hermetically connected to an opening at an upper end of a lower box body (1), and the lower sealing plate (3) can move up and down along an inner wall of the lower box body (1); an opening at a lower end of an upper box body (11) is hermetically connected by means of an upper sealing plate (8); a workpiece (5) to be machined is arranged between the upper sealing plate (8) and the lower sealing plate (3), and a rapid heater (2) is arranged at the bottom of an inner cavity of the box body (1); a piston (18), which is matched with an inner wall of the upper box body (11) and can move up and down, is arranged in an inner cavity of the upper box body (11), and the piston (18) is fixedly connected to the top of the upper box body (11) by means of a spring (17); and the rapid heater (2) heats a liquid, the spring (17) is compressed and rebounds, and the liquid flows across a surface of an inner hole of said workpiece (5). A polishing method of a reciprocating abrasive flow polishing device based on a cavitation effect is also included. By means of the reciprocating abrasive flow polishing device and the polishing method thereof, liquid flows bidirectionally in an inner hole, thereby reducing the kinetic energy loss of the liquid when flowing through an elongated hole and mitigating the non-uniform roughness of inner surfaces of two ends of the hole.
