PURPOSE: To provide an internal ring-fitting device which is as light-weight and dimensionally small as being fittable in a robot hand by a method wherein a clamping means which respectively corresponds to two kinds of internal rings with different shapes is provided on a slide block, and the pressure of an air cylinder for clamping is switched into two stages. ;CONSTITUTION: For a ring clamping part, a main shaft 21 is provided at the center of a main plate 11, and 4 units of slide blocks 24 which are movable in the radial directions are attached to the main shaft 21 in the radial directions with an equal interval. Also, as an equalizer mechanism, a cross-shaped equalizer arm 22 is rotatably attached to the main shaft 21, and the equalizer arm 22 and respective slide blocks 24 are connected with a link plate 23. In addition, as a slide mechanism, respective slide blocks 24 are moved in the radial directions by 4 units of clamping cylinders 25. The pressures of the clamping cylinders 25 are switched into two stages depending on the kind of ring. By this method, one unit of robot can correspond to all kinds of internal rings.;COPYRIGHT: (C)1996,JPO
