Fabricated building material processing device capable of conveniently fixing plates

The utility model relates to the technical field of fabricated building material processing, in particular to a fabricated building material processing device convenient for fixing a plate, and solves the problems that in the prior art, the fixation of the fabricated building material is not stable enough, so that the punching accuracy of a punching mechanism in the processing device on the plate is possibly reduced, and the machining efficiency is improved. And for a plate with a large size, under the condition that the stress area of the plate is small only through a fixing mechanism, the situation that the plate shakes and is not stable enough possibly occurs, and therefore the machining efficiency is affected is solved. The fabricated building material processing device facilitating plate fixing comprises a workbench, a top plate is arranged above the workbench, and transverse plates are fixedly connected to the outer walls of the two sides of the workbench and the outer walls of the two sides of the top
