ABSTRACT:
Gripping device (1), primarily intended for handling objects of circular cross-section such as shafts, round metal plates or rings with the aid of industrial robots. It comprises three parallel shafts (10a, b, c) with gripping arms with gripping members (11a, b, c). The shafts (10a, b, c) are rotatably journalled in a plane supporting member (2, 3). A drive motor (16) drives one shaft (10a). The other shafts (10b, 10c) are connected together with the driven shaft (10a) by means of gear wheels (14a, b, c), one on the driven shaft (10a) and one on either of the other two shafts (10b, 10c), and two racks (20a, 20b) in mesh with the gear wheel (14a) on the driven shaft (10a) and one of the gear wheels (14b, 14c) on the other shafts (10b, 10c).
