The invention provides a workpiece transferring device. The workpiece transferring device is used for transferring workpieces arranged in the first direction and comprises a shell provided with an inner cavity and further comprises a driving structure. A rotating clamping piece and a lifting clamping piece are contained in the inner cavity of the shell; a first through groove and a second throughgroove which penetrate through the outer wall of the shell into the inner cavity are formed in the shell in the first direction; the rotating clamping piece extends out of the shell through the firstthrough groove and can retract into the inner cavity of the shell; the lifting clamping piece extends out of the shell through the second through groove and can retract into the inner cavity of the shell; and the driving structure drives the shell to move in the first direction, the rotating clamping piece is used for clamping the workpieces to move , and the lifting clamping piece is used for positioning the workpieces. In this way, the lifting clamping piece positions the workpieces, the rotating clamping piece clamps the workpieces to move to complete resetting of the workpieces, compared with an existing method that manpower is used, the labor intensity is relieved, and the production efficiency is improved.
