The invention discloses an adjustable workbench based on stone artware production. A main machine body is included. An auxiliary body is fixedly arranged on the rear side face of the main machine body. A table is fixedly arranged on the top face of the main machine body. Two left-right-symmetry moving cavities with upward openings are formed in the table. The bottom wall of the moving cavity located in the left side is provided with a clamping block in a sliding manner, and the right side face of the clamping block is provided with a clamping mechanism capable of clamping stone and controllingstone rotation. A moving mechanism capable of controlling the left-right movement of the clamping block is arranged in the moving cavity located in the left side. The adjustable workbench integratesproducing and machining functions of multiple stone artware, the complete set of procedures for the stone artware can be finished on one workbench, production is more convenient, and more efficiency is achieved. The clamping mechanism and the moving mechanism can clamp the stone in a pneumatic manner.
