Abstract
The utility model discloses a membrane chuck centering device which comprises a fixture, a membrane, a plurality of jaws, a plurality of ejector rods, a plurality of bearing pins, a gear workpiece and a pre-tensioner ring. The fixture is of a circular structure; the membrane is of a circular structure, and the peripheral edge of the membrane is arranged on the front surface of the fixture via bolts; the multiple jaws are uniformly arranged on the membrane around the same circumference; the multiple ejector rods are uniformly arranged on the back of the membrane and are used for pushing the membrane, so that the membrane can deform; the multiple bearing pins are uniformly arranged in circles around the same circumference, and the circles are formed by the jaws; the pre-tensioner ring is arranged above the multiple bearing pins and is used for preventing the gear workpiece from being abraded by the bearing pins. The membrane chuck centering device has the advantages that the membrane chuck centering device is specially used for centering the fixture for the gear workpiece and is high in centering precision; high clamping force can be generated for the gear workpiece, and the workpiece can be protected from being easily damaged.
