Background technology
The bidimensional angular setting two plate mechanisms that adopt, related with three kinematic pairs between fixed head and the adjustable plate, the locus by the kinematic pair interface changes the attitude adjusting that realizes adjustable plate more.This mechanical feature is: simple in structure, it is little to take up room.Connect by higher pair between adjustment component and the adjustment bearing: ball-hole, ball-groove, ball-plane, use the spring tension between two plates, static drift is bigger, usually can cause stable decline in actual use.
Summary of the invention
The purpose of this utility model is to improve three the kinematic pair connected modes and the overall configuration of above-mentioned existing two plate mechanisms, improve its stability, a kind of frame type two-dimensional high precision adjusting rack is provided, that this adjustment rack should have is simple in structure, process and assemble convenient, volume is little, can overcome static drift, the characteristics of good stability.
Technical solution of the present utility model is as follows:
A kind of frame type two-dimensional high precision adjusting rack comprises framework and picture frame, it is characterized in that at the side of described picture frame three steel balls being installed, and wherein first ball is in upper left side and the nut and the sphere trim ring formation ball pair of framework; Second ball and first lever, groove pressing plate form the groove pair; The 3rd ball and second lever form planar contact pair; The extended line of described ball pair and groove pair is perpendicular to the line of ball pair and planar contact pair, the nut seat of one pitch regulation screw mandrel is fixed on the framework, the screw mandrel of pitch regulation screw mandrel withstands on first lever, realizes that with the spring tension pitch regulation resets between the described nut seat and first lever; The screw mandrel that one beat is regulated screw mandrel withstands on second lever, and the nut seat that beat is regulated screw mandrel is fixed on the framework, realizes that with the spring tension beat adjusting resets between this nut seat and second lever.
Described pitch regulation screw mandrel and beat are regulated screw mandrel and are adopted the lever sub-structure, and this lever sub-structure is the wedge shape oblique mechanism.
Technique effect of the present utility model:
1, described ball pair, groove pair and planar contact pair three steel balls of hard-pressed bale hoop in the picture frame plane increase space orientation rigidity, and the mirror holder overall configuration is a closed-in construction simultaneously, mirror holder resistance to overturning height.The secondary restriction of ball three degree of freedom, two degree of freedom of the secondary restriction of groove, planar contact pair restriction one degree of freedom.The secondary extended line of ball pair and groove is the secondary and planar contact pair line perpendicular to ball all the time, and when bidimensional was regulated, the bidimensional relevance reduced.
2, in small space, use segmentation mechanism, increase degree of regulation as leverage.Segmentation mechanism also can adopt the wedge shape oblique mechanism to increase degree of regulation.
3, the utility model has overcome the static drift of conventional bidimensional adjustment rack, has increased the stability of adjustment rack, and adjusts the precision height.Therefore in trim, have great superiority and promotional value such as the chamber mirror of the resonator cavity of fiber optics and various miniature lasers.
