DEVICE FOR PROCESSING SPECIAL-SHAPED INNER HOLE CURVED SURFACE USING ABRASIVE FLOW

WIPO Patent Application WO/2021/036490

A1

A device for processing a special-shaped inner hole curved surface using abrasive flow, comprising an abrasive flow processing machine (1). A storage box (2) is installed at the top of the inside of the abrasive flow processing machine (1); a limiting sleeve (9) is provided on the outside of the abrasive flow processing machine (1) and at the bottom of the storage box (2); the top of the abrasive flow processing machine (1) is fixedly connected to the limiting sleeve (9) by means of a first cylinder (8); and the upper end surface of the limiting sleeve (9) is a closed structure, and the lower end surface is an open structure. In the abrasive flow processing device, after an object is put into a polishing space, the first cylinder pushes the limiting sleeve to move close to the object; a second cylinder inside the limiting sleeve pushes a cover plate to move close to the upper end surface of the object; then, a booster pump is started to enable abrasive particles to quickly flow into the cover plate by means of a telescopic rod, and the abrasive particles flow into a special-shaped inner hole under the squeezing force of the cover plate and the object to provide sufficient abrasive flow, such that the object is polished by means of the cover plate, without needing to consider the outer diameter of a hole, thus fully improving the efficiency of the abrasive flow in the special-shaped inner hole.
