Abstract
The invention discloses a micro-adjusting mechanism used for the internal reflection prism angle of a small lens cone. The micro-adjusting mechanism comprises a main base on which the whole mechanism is packaged, a hanging bracket which is arranged in the middle part and a micro-adjusting frame which is arranged on the upper part. The hanging bracket and the micro-adjusting frame are fixedly connected through a pressing ring. A cover ring and a hanging plate of the micro-adjusting frame are connected by three springs. The corresponding positions of the cover ring and the hanging plate are respectively provided with three countersink holes in which screws are screwed in and then the countersink holes are connected with the springs in a matching way. Axial and radial positioning of the cover ring is realized through the main base. Upward and downward micro-adjustment of the hanging plate is realized through screwing and unscrewing of bolts in the two bolt holes in the cover ring. According to the micro-adjusting mechanism, three-point leveling is realized by utilizing scalability of the three springs. The micro-adjusting mechanism is simple in structure and low in device cost and can realize real-time online optical path micro-adjustment through screwing the bolts outside the device so that the situation that the optical path deviates and then the angle of the reflection prism requires to be set again by disassembling the mechanism and then arrangement is performed again for detection can be avoided, and thus adjusting precision is high and operation is convenient.
