The utility model relates to the technical field of nut feeding, and discloses a nut feeding gripper which comprises a mounting plate, a first positioning hole is formed in the outer side of the mounting plate, a fixing plate is fixedly mounted on the outer side of the mounting plate, a second positioning hole is formed in the outer side of the fixing plate, and a control module is fixedly mounted on the outer side of the fixing plate. A mounting block is fixedly mounted at the bottom of the mounting plate, a third positioning hole is formed in the outer side of the mounting plate, and a bolt is fixedly mounted on the outer side of the mounting block. According to the nut feeding gripper, through the design of the first groove and the nut body, the positioning effect can be achieved when the nut body is taken, the clamping block is clamped into the nut body, and the situation that displacement is likely to happen in the moving process is avoided; through the design of the two clamping air cylinders, the baffle, the guide rail, the limiting groove, the first limiting block, the positioning block, the clamping jaw, the second groove and the second limiting block, two nut bodies can be clamped at the same time, and therefore the grabbing efficiency of the whole gripper is improved, and the production efficiency is improved.
