Problems solved by technology

For example, there are some two-dimensional inclination adjustment structures that are simply superimposed using one-dimensional inclination adjustment structures. When they are adjusted, the adjustment in one direction will always affect the adjustment in the other direction, resulting in cumbersome adjustments and low precision; The two-dimensional inclination adjustment structure of Dingsanla is convenient and flexible to adjust, but its stability is poor, and it is easy to change in a vibrating environment; there is also a multi-dimensional adjustment table on the market, which does not have the disadvantages of the previous two structures , but the volume is not easy to make small

Abstract

A plane two-dimensional inclined angle adjuster mainly solves the problem that the plane included angle is simultaneously adjusted and locked and is suitable for adjusting the inclined angle at a high precision. A moving piece is fixed by a spherical line contact interference compressing method through a designer, and two inclined degrees of freedom of the moving piece in a planar normal can be ensured and the translation degree of freedom of the moving piece is limited; the rotating degree of freedom of the moving piece is limited by adopting an adjusting piece with a symmetrical inclined V-shaped groove structure and the adjustment and the locking can be performed simultaneously; the moving piece is in steel ball transition with an upper cover plate and an adjusting piece and the adjusting piece is in pin roller transition with the base, so as to reduce the static friction force; and through the driving piece, the angle of the moving piece is adjusted by adopting a manner of driving the adjusting piece through threads.

Description

technical field [0001] The invention relates to a planar two-dimensional inclination adjuster suitable for precision photoelectric equipment, which is a structure for realizing high-precision two-dimensional inclination adjustment by using a spherical surface and an inclined surface. Background technique [0002] Tilt adjustment has application examples in almost all fields. Among them, there are many one-dimensional inclination adjustment structures and they are very mature, such as wedge rings. These structures have high adjustment accuracy and are compact and very practical. Compared with the one-dimensional tilt adjustment structure, there are many kinds of two-dimensional tilt adjustment structures, but these structures have more or less disadvantages. For example, there are some two-dimensional inclination adjustment structures that are simply superimposed using one-dimensional inclination adjustment structures. When they are adjusted, the adjustment in one direction ...
