Abstract
The invention discloses a high-precision displacement fine-tuning device, which comprises a roller and two parallel frame guide rails. The device is characterized in that two parallel outer sliding blocks are arranged between the two frame guide rails. The two outer sliding blocks are integrally connected together and the end parts thereof are connected with an output rod. An inner sliding block is arranged between the two outer sliding blocks. One end of the inner sliding block, corresponding to the output rod, is provided with an input rod. The roller is composed of a central inner roller part, intermediate roller parts symmetrically placed on the two sides of the inner roller part, and outer roller parts symmetrically placed on the two sides of the intermediate roller parts. The inner sliding block is provided with clamping parts capable of being clamped with the intermediate roller parts. The intermediate roller parts are respectively connected with the outer sliding blocks. The outer sliding blocks are respectively connected with the frame guide rails. The inner roller part, the intermediate roller parts and the outer roller parts are sequentially increased in radius. In this way, the displacement offset generated between the sliding blocks and the roller during the adjustment process cam be reduced. Meanwhile, the adjustment accuracy is improved.

Technical field
The present invention relates to a kind of high precision displacement micromatic setting.
Background technology
General, the equipment such as optical lens, milling machine all needs a high precision displacement micromatic setting, regulate for the rotation of knob being changed into corresponding straight-line displacement, in prior art, the structure adopting roller and slide block to combine realizes this adjustment, and structure is simple, but also there is a deficiency simultaneously, that is: slide block and roller easily produce displacement bias in the process of relative sliding, cause regulating occurring large error, affect the use of equipment.
Summary of the invention
For the problems referred to above, the invention provides a kind of high precision displacement micromatic setting, reduce the displacement bias produced between slide block and roller in adjustment process, improve degree of regulation.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of high precision displacement micromatic setting, two rack rails comprising roller and be arranged in parallel, it is characterized in that, two outer slides be arranged in parallel are provided with between two rack rails, two outer slides are connected and end is connected with take-off lever, inner slide is provided with between two outer slides, described inner slide one end corresponding with take-off lever is provided with input lever, described roller comprises the interior roller portion at center, be positioned at the mediate roller portion that roller portion symmetria bilateralis is arranged, be positioned at the outer roller portion that mediate roller portion symmetria bilateralis is arranged, described inner slide is provided with the holding section that can fasten with mediate roller portion, described mediate roller portion is connected with outer slide respectively, described outer roller part is not connected with rack rail, described interior roller portion, the radius in mediate roller portion and outer roller portion increases successively.
Preferably, described interior roller portion is connected with inner slide by flexible belt, and described mediate roller portion is connected with outer slide by flexible belt, and described outer roller portion is connected with rack rail by flexible belt.
The invention has the beneficial effects as follows: be not an independent point or face contact slide between inner slide and mediate roller portion, but engaging contact slide, reduce the displacement bias produced between slide block and roller in adjustment process, improve degree of regulation.By arranging the radius in interior roller portion, mediate roller portion and outer roller portion, realize high-precision ratio of gear, easy to use.
