摘要:
The invention relates to a positioning device for objects, especially for pneumatic manipulator devices, which is provided with positioning means for positioning in at least one spatial direction. The positioning means (33) engage in a holding device (17, 30, 34) for the object (10, 11) that is to be positioned, which is connected to the holding device (17, 30, 34) by a pneumatic actuator array (23), wherein the positioning direction of the actuator array (23) corresponds to the directions or one of the directions of the positioning means (33). The fine positioning actuator array (23) consists of at least one contraction element that has a contraction tube (26) extending between two head pieces (24, 25), said contraction tube contracting longitudinally when inner pressure is exerted.
