FIELD: machine building.
SUBSTANCE: invention refers to positioning device. Positioning device has support structure, fixing device for the processed item and support stacks adjusted in length connected to the support structure from the one side and fixing device from the other side. At this the support stacks are installed movable in the points of connection with support structure and fixing device. At least one part of support stacks is made so that its length can be adjusted and at least one of the support stacks has drive to be adjusted in length. At least six support stacks are installed in couples into the triangle. At this at least in two couples of support stacks the support stacks shall be parallel. Each stack couple has common drive by which it can synchronously be adjusted in length. At this each couple of support stacks at the first end of the lengthwise course of support stacks has turn bearing and at the second end of the lengthwise course of each support stack - the second bearing.
EFFECT: invention allows creating compact highly hard positioning device.
