Description

Optical adjustment mount

technical field

The utility model relates to an optical adjustment device, in particular to an optical adjustment frame.

Background technique

At present, in optical experiments and laser applications, in order to solve the problem of adjusting the optical path, people often use an optical element orientation adjustment device, such as the laser radar adopted by the applicant. It consists of a frame, a mirror frame, and springs connected to them on the semicircle of the same diameter, adjusting screws and fastening screws. Among them, the central angles between the three adjusting screws are all right angles, and all of them pass through the frame. The screw holes of the lens are in contact with the mirror frame; there are also three fastening screws, and the central angles between them and the adjusting screws are all 45 degrees, and they are pulled together through the through holes on the frame and the screw holes on the frame. fixed; five springs are evenly distributed between the adjustment screw and the fastening screw, and the two ends of the spring are respectively hooked in the through holes of the stand and the mirror frame. When adjusting, adjust the optical path by rotating the adjusting screw, and then lock it with the fastening screw. But there are deficiencies in this device. At first, the three adjustment screws arranged on the semicircle, each of which is both an adjustment point and a support point, when adjusting a certain orientation, it is easy to cause other orientations to also occur. Slight changes make it extremely difficult to adjust the optical path; secondly, the spring and the adjustment screw are in point contact with the frame, and the spring in it is easy to absorb external forces with its own twisting deformation, and the adjustment screw is a sliding top contact, so Although the adjustment is sensitive, it is unstable, and it is easy to cause slight changes in the frame in multiple directions; again, when the fixed screw is used to lock the adjusted frame, it will also destroy the balance plane formed by the sliding top of the three adjustment screws , that is to say, it must be adjusted and tightened repeatedly before it can be successful; finally, because it is connected by springs, the weight of the frame and the lens fixed on it will easily cause a slight change in the orientation of the frame. It is especially obvious when the attitude changes, making it poor in anti-vibration ability.

Contents of the invention

The technical problem to be solved by the utility model is to provide an optical adjustment frame to overcome the deficiencies in the prior art.

The adopted technical scheme includes that the frame with the recessed table hole and the internal thread hole is connected with the mirror frame provided with the recessed table hole through elastic connectors and screws. There are two parts and screws, and the central angle between the two internally threaded holes is a right angle. In particular, there are steel balls between the frame and the mirror frame, and the steel balls, elastic connectors and screws are arranged in a straight line. , the said elastic connector is that the two ends of the bolt penetrating through the concave table hole are hung with elastic discs.

As a further improvement of the technical solution, the contact between the frame and the mirror frame connected with the steel ball is a spherical pit; the steel ball is located at the center of the frame and the mirror frame; the bolt is an internal thread rod There are screws at both ends; the screws are ball-head screws.

Compared with the beneficial effects of the prior art, firstly, the existence of steel balls, and setting them in a straight line with elastic connectors and screws, not only make the only common support point between the frame and the frame, but also make the frame Only one-dimensional azimuth adjustment can be made along the straight line, without affecting other azimuths or being disturbed by other azimuth adjustments, that is, whether it is adjusting one azimuth or adjusting two azimuths at the same time, it will only affect the adjusted The orientation of the two orientations works, so that the adjustment of the two orientations does not interfere with each other, and it is easy to adjust successfully in one step; second, the elastic disc in the elastic connector is in contact with the frame and the frame, and the elastic disc After the disc is squeezed, it will not be twisted, making it sensitive and stable to adjust; thirdly, the force of the elastic disc has a large area and is evenly distributed, so it does not need to be tightened after adjustment. The ability to be affected by temperature changes is strong; Fourth, the structure is simple, easy to use, reliable, and practical.

Description of drawings

The preferred mode of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

Fig. 1 is a kind of basic structure front view of the utility model;

Fig. 2 is a partial cross-sectional view along line A-A shown in Fig. 1 .

Detailed ways

Referring to Fig. 1 and Fig. 2, the disc-shaped mirror frame 2 is provided with two concave platform holes 5 positioned on the same diameter circle, and the central angle between the two concave platform holes 5 is a right angle; The two concave table holes 10 corresponding to the concave table holes 5 on the frame 2 and the internally threaded holes 8 of the two inner-rotating ball head screws 9; Two bolts 4 formed by internally threaded rods with screws 41 at both ends run through two pairs of recess holes (5, 10) respectively, and five elastic discs 6 and one Only the gasket 7 and the screw 41 compress the elastic disc 6 and the gasket 7 on the hole platform of the concave table hole (5, 10); the steel ball 3, the bolt 4 and the ball screw 9 are arranged in a straight line.

When in use, after the utility model with optical elements fixed on the mirror frame 2 is placed on the optical path, the required optical path can be adjusted quickly only by adjusting the ball screw 9.
