Description
Technical field
The utility model belongs to the fiber manufacturing field, relates in particular to a kind of optic fibre turning proving installation.
Background technology
The optical fiber unrelieved stress has two classes, one class is the unrelieved stress between fiber optic materials and matrix, be called internal residual stress, one class is the stress that outer fiber applies, being called outside unrelieved stress. internal residual stress is mainly that the optical fiber inhomogeneous cooling in drawing process is even, there are the reasons such as impurity to cause in material,. outside unrelieved stress be in the coiling process to stranding turn round, stretch, the generation such as extruding, internal residual stress is to be difficult for eliminating, and outside unrelieved stress generalized case has not just existed after external force disappears yet.
Fibre ribbon is produced to be reversed.GB has also been stipulated the residual torsional stress method of testing of fibre ribbon, but optical fiber is different with fibre ribbon, the distorting stress of optical fiber can discharge after two unclasps, fibre ribbon produces because of optic fibre turning and reverses, the optical fiber rear formation fibre ribbon that is cured, can also can not disappear by stress after distorting stress can not discharge so unclasp, therefore with the method for surveying the fibre ribbon residual torsional stress can not measuring fiber residual torsional stress.And patent CN1517688 discloses the device of unrelieved stress in a kind of measuring optical fiber.This device comprises: light source, and emission is used for the light beam of measuring optical fiber unrelieved stress; Polarizer carries out polarization to light beam, and light beam is converged to optical fiber; And microslide, be provided for supporting the optical fiber that will measure its unrelieved stress.Described device also comprises: analyzer, be arranged on the position relative with microslide, and be used for covering and supporting optical fiber, and be used for passing through selectively from the predetermined polarisation component of the light beam of optical fiber incident; And detecting unit, be used for carrying out visual to passing the light beam of coming from analyzer.It is the sort of unrelieved stress that but this measurement mechanism can not be differentiated, some unrelieved stress may not affect the use of optical fiber, just disappeared as pushing, being stretching in the unwrapping wire process, and inner unrelieved stress we also can embody by the size of decay and the size of curvature, and twisting stress can not be reacted by this method of testing, and is difficult for eliminating in follow-up production.
Summary of the invention
The utility model purpose is to overcome the deficiency of above prior art, and a kind of simple in structure, optic fibre turning proving installation that the benchmark degree is higher is provided, and specifically has following technical scheme to realize:
Described optic fibre turning proving installation is connected with fiber reel, comprises cover body, back shaft, pointer, angle gauge, guide rail bracket and angle gauge moving guide rail, the bottom of described cover body is connected on guide rail bracket, and described back shaft is supported in the top of cover body rotationally by bearing, and described angle gauge moving guide rail is connected on guide rail bracket slidably, described angle gauge is located on the angle gauge moving guide rail, be fixed with described fiber reel on described back shaft, fiber reel tightens cover has optical fiber, described pointer to be connected in an end of optical fiber.
The further design of described optic fibre turning proving installation is, described back shaft an end connect the leader.
The further design of described optic fibre turning proving installation is, described cover body is a semiclosed rectangular parallelepiped without end face, and the one side at least of cover body is the organic glass panel, and the height of cover body is 1.2m-1.5m.
Advantage of the present utility model is as follows:
Described optic fibre turning proving installation has realized that reliability is high to the test of optic fibre turning stress; It is simple in structure, and is practical, has higher operability; Measure simultaneously precision higher.
Description of drawings
Fig. 1 is the structural representation of described optic fibre turning proving installation.
In figure, 1-cover body, 2-back shaft, 3-bearing, 4-pointer, 5-angle gauge, 6-guide rail bracket, 7-angle gauge moving guide rail, 8-fiber reel, 9-optical fiber, 10-handle.
Embodiment
Below in conjunction with accompanying drawing, the utility model scheme is elaborated.
Contrast Fig. 1, the optic fibre turning proving installation that the present embodiment provides, comprise cover body 1, back shaft 2, pointer 4, angle gauge 5, guide rail bracket 6 and angle gauge moving guide rail 7, the bottom of cover body 1 are connected on guide rail bracket 6, and cover body 1 is a semiclosed rectangular parallelepiped without end face, the one side of cover body 1 is the organic glass panel, facilitates the observer that the measurement result of angle gauge is read.The height of cover body 1 is 1.2m-1.5m.Back shaft 2 is supported in the top of cover body 1 rotationally by bearing 3, an end of back shaft 2 connects leader 10.Angle gauge moving guide rail 7 is connected on guide rail bracket 6, and can be free to slide along four direction up and down.Angle gauge 5 is connected with angle gauge moving guide rail 7.Being fixed with fiber reel 8 on back shaft 2, on fiber reel 8 there is by the fixing optical fiber 9 of fixture (not shown in FIG.) cover.Pointer is connected in an end of optical fiber, is suspended in the below of fiber reel and remains static.
during use, angle gauge 0 is spent the angle to be adjusted to parallel with back shaft, after unclasping slowly swing handle make the slow unwrapping wire of fiber reel, until optical fiber is near angle gauge, then according to circumstances the position of the mobile angle gauge central point that makes optical fiber and angle gauge over against, the deviation angle of pointer on angle gauge is exactly the windup-degree of test, but the testing staff will note observing, if when windup-degree is spent over 360, the meeting of final test is smaller, we are the torsion number of turns 1 circle 360 degree of necessary recording process pointer also, 2 circle 720 degree, and then add the data of final test, angle that like this can the Measurement accuracy optic fibre turning, measuring accuracy is 1 degree.The torsion of general optical fiber can not surpass 360 degree in 1 meter scope.
