Woodcarving grinding machine capable of automatically and comprehensively grinding woodcarving

The invention discloses a woodcarving grinding machine capable of automatically and comprehensively grinding a woodcarving. The machine comprises a grinding box and a grinding cavity arranged in the grinding box, wherein an electric sliding rail is fixedly arranged on the upper cavity wall of the grinding cavity, and a grinding air cylinder is arranged on the lower end face of the electric slidingrail in a sliding mode. After the machine is used, when the woodcarving is clamped, the approximate size of the woodcarving is obtained, polishing plates on the two sides get close to the woodcarving, polishing wires on the polishing plates are attached to the woodcarving, in order to prevent gaps from being formed in the woodcarving, the polishing plates are further moved by a certain distance when getting close to the woodcarving, the polishing wires are better attached to the woodcarving, and then the polishing plates are rotated through a motor to polish the woodcarving; the working efficiency is improved, it is
