Technical field
The utility model belongs to optical instrumentation technical field, especially relates to a kind of V-groove self-calibrating device.
Background technology
At present, the V-groove of V-prism refractometer is fixed on the guide rail of V-prism refractometer using screw lock mode.In the presence of
The problem of be：
(1) during fixed V-groove, it is desirable to V-groove left surface perpendicular to parallel light tube outgoing horizontal light,
But because traditional screw lock mode can not ensure this point.
(2) due to manual operation difference, every time during fixed V-groove, the position of V-groove can not ensure one
Cause.These problems can cause the positioning of V-groove position inaccurate or inconsistent, and the measurement for being easily introduced glass refraction is missed
Difference.
Therefore being needed badly among prior art wants a kind of new technical scheme to solve this problem.

Control circuit 2 is transferred to, the control control two-dimensional precision rotating platform 3 of circuit 2 is operated, and drives V-groove 4 to realize that azimuth pitch and direction are anti-
Polyphony section, real-time Slit Image position heretofore is overlapped with reference position, and the position correction of V-groove 4 is completed.
The utility model uses two-dimensional precision rotating platform 3, and V-groove is fixed instead of conventional screw retaining mechanism, can not only be quick
Precise positioning V-groove position, makes it vertical with the parallel rays holding of the outgoing of parallel light tube 1, and can guarantee that, each V-type
The position consistency of groove, improves the accuracy and uniformity of glass refraction.The utility model, will twice using digital alignment
Slit Image grid deviation obtains the optimum position of V-groove as control signal, control two-dimensional precision rotating platform fine setting.
