The utility model discloses a jaw type automatic centering clamping structure. The jaw type automatic centering clamping structure comprises a clamp and a clamping air cylinder, wherein the clamp is matched with one end of a product workpiece in a supporting positioning mode, and the clamping air cylinder is perpendicularly installed below the clamp. A guiding sliding hole is formed in the clamp in a through mode, a pressing resetting block is arranged inside the guiding sliding hole in a sliding mode and controlled by the clamping air cylinder to move in the vertical direction, movable locking blocks are arranged on the clamp in a bilateral symmetry mode and used for clamping the product workpiece from two side face of the product workpiece in a jaw mode, and an inclined wedge block is machined in the center of the pressing resetting block and synchronously extrudes and pushes the movable locking blocks on the two sides in a sliding mode so that opposite rotation clamping can be achieved. The jaw type automatic centering clamping structure is simple, short in clamping stroke and capable of positioning the product while clamping the product, and effectively solving the problem that because one end of a special product is suspended in midair, knife vibration and deformation occur, and saving the space.
