Surface double-layer polishing equipment for building wood processing

The utility model discloses surface double-layer polishing equipment for building wood processing, and aims to solve the problems existing in existing building wood double-surface polishing. The polishing device comprises a workpiece fixing frame, a support and a polishing assembly. The supports are symmetrically arranged on the two sides of the workpiece fixing frame. The workpiece fixing frame is provided with a clamping groove used for being clamped into building wood. The supports are connected with the rotating shafts, the polishing assemblies are fixed to the rotating shafts, a user clamps the building wood in the clamping grooves, the upper end face and the lower end face of the building wood correspond to the polishing assemblies of the two supports respectively, the polishing assemblies work to conduct double-layer polishing on the surface of the building wood at the same time, the labor amount of work is reduced, and the polishing efficiency is improved. Through cooperation of all the components, th
