Description

The utility model belongs to an adjustable mirror frame used in the optical path.

In optical instruments or optical experiments, the path that light travels is called the light path. In order to make light travel along a certain route, various lenses and mirrors must be placed in the optical path, and they must be accurately adjusted to certain positions and angles. In order to make the optical path advance according to the requirements of the experiment or instrument work, the lens and mirror must be installed on the mirror frame that can be adjusted slightly in multi-dimensional directions, and the requirements can be met after fine-tuning.

The existing mirror frame is composed of a mirror frame, a base, two mutually fitted frames and three spiral micrometers, etc., the larger one of the frames can slide on the base, the base moves back and forth, the frame moves left and right and up and down It is accomplished by the screw rotation of three screw micrometers. The picture frame is installed on a smaller frame, and due to the translation of the frame, the picture frame can move in translation in the three-dimensional directions of front and back, left and right, up and down, so as to achieve the purpose of adjusting the lens and reflector. This kind of mirror frame has the advantages of high adjustment accuracy, but it also has the disadvantages of large volume, which easily blocks the optical path, and because of the complex structure, the cost is high, and it can only be adjusted in three dimensions in space, especially for optical instruments. Not very popular.

The multi-dimensional micro-adjustment mirror frame of the present invention is designed to overcome the above-mentioned shortcomings. It can not only adjust the three-dimensional linear motion, but also perform 360° rotation adjustment and pitch adjustment. It has the characteristics of simple structure, small size, and low cost. Meet the requirements of various factors of optical path adjustment.

Structure of the present utility model is provided by Fig. 1. Figure 1 is a structural diagram of a multi-dimensional micro-adjustment mirror frame. In Figure 1, 1 is the countersunk head fixing screw, 2 is the left and right translation adjustment screw, 3 is the floor frame, 4 is the upper slider, 5 is the left and right translation slider, 6 is the screw spring clip, 7 is the up and down translation adjustment screw, 8 9 is a mirror, 9 is a picture frame, 10 is a pitch adjustment screw, 11 is a shrapnel, 12 is a lower slider, and 13 is a fastening screw.

Floor frame 3 is the concave metal plate of vertical placement, and bottom is wider and is folded into 90 ° angle from the middle, has U-shaped notch in the middle of horizontal part, so that press with fastening screw 13 and base. The lower slider 12 is also a concave metal frame, and the inner sides of the vertical parts on both sides are made into oblique planes, that is, the inner surface and the front plane are not perpendicular, but form a certain angle, which is called a dovetail bevel, so that the lower slider 12 The front and rear front face widths of the front and back are different. The narrower side of the front surface width is aligned with the base plate frame 3 and fixed together with the countersunk head fixing screw 1, so the dovetail groove of the up and down direction is formed in the inboard of the lower slider 12.

The upper slider 4 is a □-shaped metal frame, and its outer surface and the front plane also form a certain angle, which forms a dovetail bevel, and matches with the dovetail groove on the inner surface of the lower slider 12, so the upper slider 4 can Slide up and down in the lower slider 12 along the dovetail groove. Have the screw hole of vertical direction respectively at the center of lower limit of upper slider 4 and the lower center of lower slider 12, and the direction of screwing of two screw holes is opposite. The direction of threads at both ends of the up and down translation adjustment screw 7 is also opposite, which can be matched with the screw holes of the two sliders. When the up and down translation adjustment screw 7 is rotated, the upper and lower parts of the screw are screwed out at the same time due to the reverse direction of the buckle. Screw in, so that the upper slider 4 and the lower slider 12 are far away from or close to, and the purpose of adjusting the up and down movement of the mirror frame is achieved.

At the center of the two side frames of the metal frame of the upper slider 4, there are screw holes on the same straight line horizontally, allowing the left and right translation adjustment screw rods 2 to pass through. One end of left and right translation adjusting screw rod 2 is used for turning and twisting, and the other end is fixed with screw rod spring clip 6. The middle part of left and right translation adjustment screw rod 2 is equipped with left and right translation slide block 5 by screw hole, promptly left and right translation slide block 5 is contained in the center of upper slide block 4 by penetrating the left and right translation adjustment screw rod 2 of its center. Picture frame 9 is used for placing lens or reflecting mirror, and is fixedly installed on the left and right translation slide block 5. When turning the left and right translation adjustment screw rod 2, the left and right translation slide block 5 drives the picture frame 9 to perform left and right translation movements.

There is a screw hole in the horizontal direction in the middle of the upper frame of the upper slider 4, and the pitch adjustment screw 10 is screwed through it. One end of the pitch adjustment screw 10 is used for twisting, and the other end passes through the top of the upper frame of the upper slider 4. On frame 9. The lower frame of the upper slider 4 is fixedly installed with the shrapnel 11 on the supporting picture frame 9 on the top picture frame 9, and the pitch adjustment screw rod 10 cooperates with the shrapnel 11, so that the picture frame 9 can be moved around the left and right translation adjustment screw rod 2, thereby adjusting The elevation angle of the lens and mirror.

Tightening screw 13 is except having the effect that whole mirror frame is fastened on the base, also can make whole mirror frame when loosening, just makes lens or reflector be fixed on any mirror frame within 360 ° around the vertical axis. In terms of angle, the front and rear adjustment can also be performed by changing the position in the front and rear direction through the U-shaped notch of the floor frame 3 .

The picture frame 9 can be designed in different shapes according to the installation of lenses and reflectors of different shapes. The whole mirror frame can be made of metal material or plastic material. Blackening treatment is required to meet the non-reflection requirements of optical equipment.

The utility model has the advantages of small size, simple structure, multiple adjustment functions, convenient use and the like. Due to the design of different structures of the existing mirror frames, manual adjustment is adopted, and the mirror frames can not only be fine-tuned front and rear, up and down, left and right, but also rotate around the vertical axis and adjust the pitch angle; Or the light path is not blocked in the experiment; it is easy to manufacture and reduce the cost due to the simple structure. The utility model is an ideal accessory in optical instruments and optical experiments.
