Hydraulic pressure suspension polishing device with controllable fluid boundary

Abstract

The invention discloses a hydraulic pressure suspension polishing device with a controllable fluid boundary. The hydraulic pressure suspension polishing device comprises a horizontal workbench, a polishing system, a lifting system, a fine adjustment system and a pressure detection system. The polishing system comprises a polishing disc, a polishing liquid container, a first coupling, a spindle, a second coupling, a motor support and a serve motor. The hydraulic pressure suspension polishing device has the advantages that a gap between the polishing disc and the wall of the polishing liquid container is small, a good condition is provided for forming good hydraulic pressure, and accordingly the machining efficiency and the surface machining effect can be improved; a polishing tool is separated from a workpiece, and the workpiece is immersed in the polishing liquid, so that the abrasion of the polishing tool is relieved easily, and negative effects caused by friction heat in the polishing process are reduced; the polishing disc is directly driven by the servo motor, error accumulation caused by complex transmission links is avoided, and the machining precision is improved.
