Abstract

According to the automatic polishing device and method for the sapphire of the special-shaped structure, by means of the extrusion effect of a grinding head, grinding paste generates the micro-cutting effect on micro protrusions on all the surfaces of the sapphire of the special-shaped structure, and materials are removed. The device comprises a polishing system, a precise displacement system, a clamping system and a clamping system. The polishing system can accurately adjust the position and the angle of a grinding head, and the polishing requirement of a complex structure is met; the precise displacement system can drive the clamping system and the workpiece to move in the horizontal plane, displacement can be adjusted according to polishing force data collected by the polishing system, the polishing force is constant, and the machining quality is uniform. The clamping system is responsible for positioning and clamping a workpiece, and different clamps are selected according to the structural characteristics of the sapphire with the special-shaped structure; the clamping system can achieve work such as disassembly, assembly and turn-over of the workpiece. The sapphire polishing device is uniform in machining quality, wide in application range, high in automation degree, small in environmental pollution and capable of achieving high-quality polishing of various complex structures of the sapphire of the special-shaped structure.
