ABSTRACT:
FIELD AND BACKGROUND OF THE INVENTION
The present invention relates in general to high precision mechanical adjusters such as those utilized on microscopes, micrometers, opto-electronics, fiber optics alignment and the like, and in particular to a new and useful high precision linear adjuster.
U.S. Pat. No. 4,617,833 discloses an adjuster which utilizes a lever system for displacement. Standard screw threads cannot provide the accuracy required of today's applications. The present invention increases precision and displacement with a finer resolution while achieving a smooth linear motion output. Backlash and output rotation are eliminated while providing smooth travel even under applied load situations.
SUMMARY OF THE INVENTION
The present invention is a high precision linear translation actuator that can be used for many applications where coarse and fine adjustment are required. The invention provides linear motion between a first member and a second output member by utilizing a drive screw within an adjustment knob to advance a drive pin which activates an angle wedge drive system located within the main body. This translates an input motion into a precise displacement at the output.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which a preferred embodiment of the invention is illustrated.
