This utility model discloses a servo synchronous adjustment and positioning worktable, including a main mounting plate. At each of the four corners of the main mounting plate are a corner driven synchronous wheel and a synchronous transmission guide assembly. The synchronous transmission guide assembly includes a linear track and a slider. A synchronous motion plate is mounted on the slider, and a positioning motion plate is mounted on the synchronous motion plate. A transmission connecting plate is mounted on the side of the synchronous motion plate. The transmission connecting plate is used to connect with a synchronous belt, and a synchronous belt pressure plate is used to fix the synchronous belt to the transmission connecting plate after position adjustment. This utility model uses a reducer to drive the active synchronous wheel to rotate. The rotation of the active synchronous wheel drives the synchronous belt to move. The synchronous belt, through the transmission connecting plate, drives the four synchronous transmission guide assemblies to move synchronously inward or outward, thereby achieving electric synchronous adjustment. This simplifies the adjustment steps, improves adjustment efficiency, and is also convenient for operation in confined spaces.
