Grinding and polishing device and system

Abstract

The invention relates to a grinding and polishing device. The grinding and polishing device comprises a grinding and polishing mechanism with a grinding head. The grinding and polishing device furthercomprises a pressure adjusting mechanism used for driving the front and back movement of the grinding and polishing mechanism to adjust the polishing and grinding strength of the grinding head; the pressure adjusting mechanism comprises an installation seat, a flexible hinge assembly and a piezoelectric promoter, wherein the grinding and polishing mechanism is installed on the flexible hinge assembly; the flexible hinge assembly is arranged on the installation seat and can deform front and back when stressed; and the piezoelectric promoter is arranged on the installation seat and connected with the flexible hinge assembly to adjust the front and rear shape variables of the flexible hinge assembly. The grinding and polishing mechanism is connected with the piezoelectric promoter and the flexible hinge assembly, through the cooperation of the flexible hinge assembly and the piezoelectric promoter, the constant force control or variable force control can be carried out in the continuousmachining process, so that the machining efficiency and machining effect are improved, and the purpose of solving the problems that multiple times of grinding and polishing due to the fact force is too small and damage of a workpiece or a cutting tool caused by the excessive force is further achieved.
