Displacement control device

Image Number 3 for United States Patent #4445273.

A device for causing a first object to perform a given, desired displacement determined by a second, fixedly arranged object that is to say, a translation and/or a rotation, particularly intended for assembling objects in industrial production processes, said device comprising a positioning means for moving the first object into a desired position with respect to the second object, comprising an auxiliary body designed for carrying the first object and journalled in a manner such that it has a plurality of degrees of freedom in displacement, driving means for each degree of freedom, a force measuring member for each degree of freedom for measuring the counter-force exerted on the first object during the displacement according to the degree of freedom concerned, feedback means between each force measuring member and the corresponding driving means, wherein the functional relationship between the displacement of the auxiliary body in accordance with a degree of freedom and the relevant counter-force is adjustable during operation.
