Clamp device for turning of internal surface of uniform-section super-thin-wall bearing ring



The utility model relates to a clamp device for turning of the internal surface of a uniform-section super-thin-wall bearing ring. The device comprises a chuck and a clamp. The clamp comprises three movable claw-wrapped clamping heads which are fixed to the edge of the chuck in an equally-spaced mode, and a circle is formed by the cross section of the three closed claw-wrapped clamping heads. The claw-wrapped clamping heads replace three original claws, and the bearing ring is free of circularity deformation. The clamp device is simple in structure, convenient to operate, high in production efficiency, capable of greatly improving clamping and positioning precision, good in machining quality and capable of meeting machining process requirements.
