Abstract
The utility model provides an axial stress adjustable fiber fixing device, it needs among the optical experiment fixed fiber to be in tensile state especially to be used in, realizes that the stress intensity is adjustable to the stress intensity keeps invariable experimentation in guaranteeing experiment operation. Characterized by: two optic fibre anchor clamps are installed on standard slide rail, can freely slide, and continuous through the spring of two parallel symmetries, two spring parameters are identical, and are well fixed through the spring hole on the anchor clamps to axial stress's equilibrium is applyed in the assurance. Be equipped with the standard scale chi on the slide rail, but accurate recording and regulating spring's reduction length, fixed one of them anchor clamps during the use change the relative position between anchor clamps according to the scale, then the fixed fiber, can realize applying the adjustment of axial stress size on optic fibre, and in can guaranteeing experiment operation, between anchor clamps the institute fixed fiber when small deformation takes place, the invariant of the automatic extension of spring in order to maintain axial stress.
Description
Technical field
This utility model relates to a kind of optic fibre fixing device, especially can freely regulate the size of the optical fiber being fixed on fixture stress vertically, and ensure the optical fiber device that suffered axial stress is constant in the range of miniature deformation..
Background technology
In recent years, the research of fiber optic communication and sensing technology receives significant attention, and the most high-accuracy optical experiment instrument equipment plays a key effect in the research and development of application technology.In laboratory environment, traditional optical fiber fixing method uses a pair fiber clamp mostly, is fixed on by optical fiber between two fixtures, and the stress being applied on optical fiber is non-adjustable.
But in a part is tested, the stress being applied on optical fiber there is is strict demand, it is necessary to assure the axial stress of optical fiber is invariable in experimentation, and stress is adjustable.Such as: the scribing process of fiber grating, need to utilize fiber clamp to fix optical fiber, and under the conditions of maintaining optical fiber to be in constant stress, grating could be inscribed.Owing to laser energy density is higher, silica fibre can be made when getting on optical fiber to produce the melted bending of small degree, cause STRESS VARIATION, affect scribing process.Applying problem to solve stress, traditional method utilizes fixture to fix optical fiber one end mostly, and the other end uses pulley, and the counterweight applying to vary in size changes stress intensity.The shortcoming of the method is to inscribe to be required for suspended counterweight again every time, and fixed position is it cannot be guaranteed that identical, and counterweight is in suspension status, easily rock, cause uneven stress to stretch, easily break optical fiber, and operational approach is loaded down with trivial details, processing method is relatively rough, affects experiment effect.
Summary of the invention
In order to solve, axial stress size in optical fiber fixation procedure is adjustable and stress maintains problem, the present invention provides a kind of adjustable optic fibre fixing device of axial stress, this device is simple to operate, flexible can be applied to the stress intensity that optical fiber is axial, and maintain axial stress constant in small scope.
The present invention solves its technical problem and the technical scheme is that two fiber clamps are arranged on slide rail, it is connected by the spring of two Parallel Symmetrics, two spring parameters are identical, well fixed by the spring eye on fixture, to ensure to apply the balance of axial stress.Slide rail is provided with master scale chi, can accurate recording and the compression degree change applying stress intensity of regulation spring.First, one of them fixture is fixed, and fixing optical fiber, according to the relative position between rule two fixtures of regulation, changing the stress intensity between fixture, the other end is also fixed on another fixture by stretch optic fibre, fixture produces axial stress to optical fiber fixed thereon under spring force state, and when there is miniature deformation in operating process, spring can automatically extend the stress intensity on maintenance optical fiber and keep constant, reaches experiment condition requirement.
The invention has the beneficial effects as follows: optical fiber fixing method simple possible, the big I of axial stress the most accurately regulates, and when can guarantee that optical fiber generation miniature deformation in experimentation, suffered axial stress is invariable.

Detailed description of the invention
In FIG, fiber clamp a(1), fiber clamp b(2) linked together by the spring (3) of two Parallel Symmetrics, spring (3) two ends are well fixed in spring eye (5).Fig. 1 shown device is arranged on slide rail shown in Fig. 2 (10), it is possible to slidably.During use, utilize the fixing fiber clamp a(1 of fixing bolt (4)), open magnetic-type clamp cover (6), pending optical fiber (8) is fixed in optical fiber fixing groove (7), magnetic-type clamp cover of closing (6), optical fiber (8) one end is fixed.
By fiber clamp b(2) promote to the left, compression spring (3), record and regulate spring (3) compression distance according to rule in Fig. 2 (9), with the fixing fiber clamp b(2 of fixing bolt (4) after mixing up), optical fiber (8) is stretched, the other end is fixed on fiber clamp b(2) optical fiber fixing groove (7) in, and magnetic-type clamp cover (6) of closing.Unclamp fiber clamp b(2) fixing bolt (4), under the elastic force effect of spring (3), to fixed optical fiber (8) apply axial stress.As fiber clamp a(1) and fiber clamp b(2) in the middle of institute fixing optical fiber (8) occur miniature deformation time, spring (3) extends adjustment in small scope automatically, keeps constant to the axial stress of optical fiber (8), reaches experiment control purpose.
