Problems solved by technology
The disadvantages of this adjustment mechanism are: (1) relying on rotating two manual adjustment levers to adjust the normal direction of the reflector, only two-dimensional inclination can be adjusted, and because the rigid support as the adjustment fulcrum deviates from the reflector The center of the normal line, the path of the spot movement is not easy to control; (2) The translation along the normal direction of the mirror is realized by the overall movement of the adjustment mechanism. This adjustment method cannot make the mirror move strictly along the normal direction, so the adjustment accuracy Low

Embodiment Construction
[0011] Such as figure 1 , 2 As shown, the adjustment seat 4 is connected to the flange of the base 1, and a threaded hole 13 is processed in the center of the adjustment seat 4, and four through holes 14 are evenly distributed on the adjustment seat 4 with the threaded hole 13 as the center. The through holes 14 constitute the four vertices of the square; four threaded holes 15 are correspondingly processed on the mirror base 5 at positions corresponding to the four through holes 14 of the adjustment base 4; four two-dimensional adjustment screws 9 pass through the adjustment base The four through holes 14 of 4 and the four threaded holes 15 on the mirror base 5 connect the mirror base 5 and the adjustment base 4 together. A spherical washer 12 is used between the two-dimensional adjustment screw 9 and the adjustment seat 4, so that when adjusting the two-dimensional inclination of the mirror, the gap between the two-dimensional adjustment screw 9 and the through hole 14 on t...

The present invention relates to a reflector three-dimensionally adjusting mechanism for adjusting the normal direction of the reflector in an optical system. The present invention has the technical proposal that an adjusting seat is fixed on a pedestal, the center of the adjusting seat has a screw thread hole, and a horizontally adjusting bolt is screwed into the top end of the adjusting seat from the screw thread hole to contact with a reflector seat; the reflector seat and the adjusting seat are joined together movably through two-dimensionally adjusting bolts, wherein a line connected by a pair of two-dimensionally adjusting bolts intersects perpendicularly a line connected by another pair of two-dimensionally adjusting bolts at the contact point of the top end of the horizontally adjusting bolt and the reflector seat. The present invention integrates the translation of the normal direction of the reflector with the two-dimensionally obliquity adjusting, has compact structure and excellent stability. Since the reflector uses the contact point of the top end of the horizontally adjusting bolt and the reflector seat as a supporting point, and the supporting point is arranged on the central position of the two pairs of two-dimensionally adjusting bolts, the facula only makes two-directions linear movement, the path of the facula is easy to be controlled, the efficiency and the precision of the adjustment are high.
Description
technical field [0001] The utility model relates to an adjustment mechanism for adjusting the normal direction of a mirror. Background technique [0002] In the optical system, it is often necessary to use a reflector to adjust the direction of light irradiation. In order to make the light incident on the reflector exit in the direction required by the system, it is necessary to adjust the normal direction of the reflector. At present, the adjustment mechanism for the normal direction of the mirror in the optical system includes an adjustment seat, two manual adjustment levers, a rigid support block, two elastic supports, and a mirror seat; the adjustment seat and the mirror seat are supported by two elastic supports , the connection line between one manual adjustment rod and the rigid support block is perpendicular to the connection line between the other manual adjustment rod and the rigid support block. The disadvantages of this adjustment mechanism are: (1) relying on r...
