Abstract
A device for trimming the thickness of a mechanical body is disclosed. The trimming is performed by screwing a screw through a threaded hole and having the end of the screw pressing against the center of a disk element, which, by deformation, acts as a lever against an adjacent body.
Claims9
A mechanical trimming device comprising:
- an adjustable screw;
- a first body having at least one threaded through hole that rotatably partly encloses said adjustable screw;
- a movable second body that is movable relative to said first body and has a cavity into said second body, wherein said cavity accommodates a proximal end of said screw when said second body is laid against said first body;
- at least one disc member having a center and an outer edge and being positioned between said first and said second bodies, wherein said cavity is facing said disc member and has an edge lying inside of said outer edge of said disc member so that said outer edge of said disc member lies between said first and said second body;
- wherein said screw, when adjusted, can raise said center of said disc member in that said disc member works as a lever having a first distributed contact point against said cavity edge of said second body and a second distributed contact point along said outer edge of said disc member against the surface of said first body, wherein said first body is moved in an axial direction of said screw with a substantially smaller motion than said screw.
A method for trimming in an orthogonal direction relative to the surface of the mechanical trimming device, wherein the method comprises adjusting a screw for raising the center of a disc member so that said disc member acts as a lever having a first distributed contact point against a second body's, relative to a first body, cavity edge and a second distributed contact point along the outer edge of said disc member against a surface of the first body.
