Abstract

Abstract A displacement control device for causing a first object to perform a given, desired displacement determined by a second, fixedly arranged abject, said device 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 menas for each degree of freedom, a force measuring member for each degree of freedom for measuring the counterforce, and feedback menas wherein 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.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 161 words
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 processe, said device comprising a positioning means for moving the first object into a desired position with respect to the second object, characterized by 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.
Claim 2
Independent Claim 161 words
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 processe, said device comprising a positioning means for moving the first object into a desired position with respect to the second object, characterized by 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.
Claim 3
Dependent Claim 23 words
A device as claimed in claim 1 characterized in that the extent of displacement resulting from the exertion of a force is adjustable.
Claim 4
Dependent Claim 23 words
A device as claimed in claim 1 characterized in that the maximum value of the driving force generating the counter-force is continuously adjustable.
Claim 5
Independent Claim 40 words
A device as claimed in claims 1 to 3 characterized in that the driving means for each degree of freedom are formed by an electric motor and in that the force measuring member measures the strength of the motor current.
Claim 6
Independent Claim 42 words
A device as claimed in anyone of the preceding claims for inserting a pin into a hole characterized in that when the hole is approached, the longitudinal direction of the pin is moved to an angle to the desired direction of displacement.
Claim 7
Dependent Claim 59 words
A device as claimed in claim 1 or 2 characterized in that at a transgression of the force adjusted at that instant in one of the degrees of freedom a higher displacing force is exerted in one of the degrees of freedom and in the case of an increase in counter-force the direction of the displacing force is changed.
