Two-degree-of-freedom fine moving and tuning adjusting rack

Abstract

A two-degree-of-freedom fine-tuning adjustment frame includes a housing, a lens, a movable block, and a lens clamping assembly. The two sides of the lens are symmetrically provided with a first adjustment rod and a second adjustment rod perpendicular to the axis of the housing. The third adjustment assembly and the fourth adjustment assembly are fixed on the front and rear sides of the lower end of the first adjustment rod, and the fourth adjustment assembly is provided with a fourth reset assembly connected with the third adjustment assembly; the upper part of the second adjustment rod and the second adjustment rod The first adjustment assembly and the second adjustment assembly are fixed on the front and rear sides, the second adjustment assembly is provided with the first reset assembly connected with the first adjustment assembly, and the second adjustment rod is fixed with the second adjustment rod on the front and rear sides of the lower end of the second adjustment rod. A positioning block and a second positioning block, the second positioning block is respectively provided with a second reset assembly and a third reset assembly connected to the first positioning block; the structure is simple, the cost is low, the reset accuracy is high, and it can be reset in a small The two-dimensional rotation adjustment of the mechanism can be realized in the same direction in the space.

Description

technical field [0001] The invention relates to the technical field of fine-tuning mechanisms, in particular to a two-degree-of-freedom micro-motion fine-tuning adjustment frame suitable for precision mechanical adjustment mechanisms of precision optical instruments and lenses. Background technique [0002] In optical experiments, in order to solve the problem of adjusting the optical path, people often use an optical element orientation adjustment device. Among these mechanisms, the traditional mechanism for angle adjustment is a three-point adaptive support mechanism or its variants, and the direction in which the adjustment rods of most adjustment mechanisms are arranged is along the optical axis. The advantages of these mechanisms are: convenient adjustment, high resolution, and are commonly used adjustment mechanisms in optical machinery. However, the structure of the above-mentioned mechanism is often complicated, the manufacturing cost is high, and the assembly is tr...

Problems solved by technology

However, the structure of the above-mentioned mechanism is often complicated, the manufacturing cost is high, and the assembly is troublesome, and there are disadvantages such as adjustment, low positioning accuracy, lagging response, and crawling during movement. The multi-dimensional micro-adjustment of the angle is realized in the direction, and the adjustment accuracy is difficult to meet the requirements
