It is after optical fiber arrangements is good that optics is turned round as device, through the compound system rod of wire drawing hot pressing, again through heating turn round the system form, the quantity of simple optical fiber does not change, two ends do not change, and the angle of image changes, certain bar straight line of promptly supposing an end is 0 degree, then in the variation of other end generation angle, uses thereby adapt to the different instruments that require.
Turning round system optics, to turn round key as device be that the optical axis of reverse part in the middle of heating is turned round in the system process still overlaps with machinery and can not be offset, to reach angle accurately simultaneously, for satisfying above-mentioned 2 requirements, traditional technology is to adopt deep bid gravity to turn round method for making, it is the center that the composite fiber rod is installed in tubular furnace that gravity is turned round method for making, and the control stove slowly heats up.After the optical fibre rod that is in high temperature section reaches softening temperature, manually unclamp the clip of torsion deep bid, survey for one of big disk and add weight, make deep bid rotate to predetermined angular after, clip is being pinned.This method equipment is simple, processing ease, but owing to be manual operation, turn round in the system process and cause angular error bigger, simultaneously because the gravity of deep bid and weight can cause the composite fiber rod two sections certain dislocation to be arranged.Cause image to be subjected to displacement.The deficiency of conventional art is that efficient is lower, and the waste of composite fiber rod is bigger.
Summary of the invention:
A kind of optics of producing is turned round the method that looks like device, it is characterized in that comprising the following steps:
The whole slowly heating that a composite fiber rod that is in horizontality is not stopped earlier, after treating that it reaches annealing temperature, begin composite fiber rod center section is further heated and imposes the torsion of plumb cut, the intermediate softening part is reversed gradually, after reaching predetermined angular, stop torsion, stop the stage casing heating, and begin integral body is slowly lowered the temperature, finally make the composite fiber clavate become two ends symmetry, big or small optics consistent, that the image angle is different to turn round the picture device.
The objective of the invention is to improve the quality and efficient, promptly having invented the accurate micromotor of system controlled by computer turns round system optics and turns round as the device and the method for can more than enough complete equipment working simultaneously, as Fig. 1, level is placed in the Optical Fiber Composite rod 11 in the miniature gradient electric furnace 12,, connect by torsion shaft 9 with jig 10 with accurate micromotor 7.When turning round system, open the system turned round order by microcomputer, acting on composite fiber rod 11 by the torsion shaft 9 that is connected with accurate electrode makes middle being heated of composite fiber rod soften at the uniform velocity rotation of part, microcomputer can once turn round simultaneously make 4 angles accurately, concentricity and the good optics of image displacement turns round the picture device, can enhance productivity four times, turn round the end product quality of making simultaneously and also improved accordingly.
Turning round needs to make composite fiber rod center section local softening and guarantees the low and softening point of two ends temperature in the system process, otherwise can influence the normal imaging of both ends of the surface, for overcoming the different temperatures of two ends temperature and center section, has adopted the gradient temperature miniature furnace.

Embodiment:
Below in conjunction with accompanying drawing shown in the embodiment, the present invention is done more into explanation.
Example of method and apparatus of the present invention such as Fig. 2, full-automatic accurate motor ladder circuit system schematic, system is installed on the support 14, one end is fixing with transmission shaft 13 with fixed knob 15, other end employing microcomputer 4 is by controller 5 and precision electric motor 7 drives transmission shafts 9 and 10 pairs of composite fiber rods 11 of jig apply torsion, make composite fiber rod intermediate softening partly begin slowly at the uniform velocity to rotate, after reaching the angle of setting, microcomputer can instruct precision electric motor to stop the rotation, because the composite fiber rod has certain viscosity under softening situation, in order to have prevented that a little from circling round, transmission shaft 9 is fixed up with knob 8.Thereby the optics of making the image angle generation of composite fiber rod two ends is turned round the picture device.
Turn round system efficient and turn round at one time and make many purpose for reaching to improve, we have adopted a microcomputer to control the way of 4 complete equipments, as shown in Figure 4.Control 4 complete equipments at microcomputer and turn round in the system again and can require send different instruction, turn round the optics of making the different size requirement in can carrying out at the same time and turn round the picture device according to difference to every complete equipment.
Turning round system optics, to turn round another key as device be owing to will guarantee that also two end faces can not burst when having than big-difference for the temperature of the temperature that guarantees both ends of the surface and center section.Therefore the present invention takes multisection type, independent temperature control, thermograde miniature furnace.As shown in Figure 3, miniature furnace is a symmetrical structure, and the axial temperature field is normal distribution in the stove.Shown in thermograde electric cooker structure figure among Fig. 3, the interior axial temperature of stove section heater strip 16,20 outside the venue adopts temperature controls, and temperature regulating device freezing of a furnace thorax two ends temperature is controlled; Inner segment heater strip 17,20 adopts another temperature regulating device that the regional temperature between burner hearth two ends and the stage casing is controlled; Stage casing heater strip 18 adopts the 3rd temperature regulating device that burner hearth stage casing temperature is controlled; By changing the cooperation of high-temperature region, stage casing thermograde and two sides temperature control, reach the effect that the intermediate softening two ends do not change, in order better to reach technological requirement, it is big that the electric furnace pipeline of the right cylinder tubulose that the present invention uses tradition is used into special two instead, middle thin build electric furnace pipeline.The present invention and traditional deep bid are turned round the difference of method for making: no matter be method of the present invention, or traditional deep bid twisting method, all need pass through the whole preheating of composite fiber rod, spot heating is to softening, turn round system and slow temperature-fall period subsequently, turn round the optics of system same size with the composite fiber rod of same specification and turn round the picture device, two kinds of method required time basically identicals, because turning round method for making, the present invention once can turn round 4 products of system simultaneously, so the method for making of turning round the more traditional deep bid of efficient has improved 4 times, turn round method for making because of traditional deep bid again, each angle orientation all needs manual operation, and error is bigger, and the inventive method is used system controlled by computer, thereby has reduced error rate.Gradient electric furnace pipeline of the present invention can make that temperature can guarantee that more medium temperature reaches softening in the pipe, and two sides temperature can guarantee not change and can also guarantee not burst phenomenon, improves the acceptance rate of product.
