Abstract
Abstract A precision adjusting system, comprising two components which can be adjusted with respect to each other, and at least two adjusting devices, each of which comprises a screw body which is mounted to be rotatable on the one component, a holder body which is rigidly mounted on the other component, and a plastically deformable torsion member which interconnects the two bodies. Rotation of the screw body causes a relative displacement of the two components, the torsion member then being twisted and plastically deformed and the two components being fixed in the adjusted position at the same time.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
74 words
A precision adjusting device, comprising a screw body, a holder body and a connecting, elongated torsion member which can be deformed by rotation of the screw body, the torsion member being made of a plastically deformable material, the ends of said member being connected to the screw body on the one side and to the holder body on the other side, the part of the torsion member situated between the two ends being twistable.
Claim 2
Dependent Claim
74 words
A precision adjusting device, comprising a screw body, a holder body and a connecting, elongated torsion member which can be deformed by rotation of the screw body, the torsion member being made of a plastically deformable material, the ends of said member being connected to the screw body on the one side and to the holder body on the other side, the part of the torsion member situated between the two ends being twistable.
Claim 3
Dependent Claim
44 words
A precision adjusting device as claimed in claim 1, wherein the torsion member has a circular cross-section, the screw body and the holder body being provided with a bore in which the twistable part of the torsion member is accommodated with a slide fit.
Claim 4
Dependent Claim
23 words
A precision adjusting device as claimed in claim 1 or 2, wherein a clearance exists between the screw body and the holder body.
Claim 5
Dependent Claim
17 words
A precision adjusting device as claimed in claim 1 wherein the torsion member is made of copper.
