Abstract
A fine displacement device for establishing a measured micro displacement includes first and second plate members disposed in spaced relation to each other to define a gap therebetween with the plate members being secured to each other at opposed portions thereof. An internally threaded hole is formed through one plate member perpendicular thereto and an externally threaded screw is fastened in the hole with an end of the screw abutting against the other plate member. Upon turning the screw in one direction, the plate members will be deformed elastically in a direction perpendicular to the plate members and a distance between a plane of the first plate member and a deformed portion of the first plate member is used as a measure for establishing the micro displacement.
Claims8
A fine displacement device for establishing a measured micro displacement comprising:
- first and second plate members disposed in spaced relation to each other to define a gap therebetween and fixed directly or indirectly to each other at adjacent portions thereof;
- and
- input means for changing said gap between said two plate members by deforming said plate members elastically in a direction perpendicular to said plate members,
- wherein a distance between a plane of said first plate member and a deformed portion of said first plate member is used as a measure for establishing said micro displacement.
A fine displacement method for establishing a measured micro displacement comprising:
- arranging first and second plate members in spaced relation to each other to define a gap therebetween;
- fixing said two plate members directly or indirectly to each other at adjacent portions thereof;
- and
- changing said gap between said two plate members by deforming said plate members elastically upon operation of input means engaging said plate members whereby a distance between a plane of said first plate member and a deformed portion of said first plate member is the measure of said micro displacement.
