Abstract
The invention discloses a jacking type clamping part used for an optical fiber preform. The jacking type clamping part used for the optical fiber preform is characterized in that the clamping part is arranged on a vertical rod vertically arranged in a suspension device, the clamping part comprises a mounting ring fixedly arranged on the vertical rod, a plurality of rib strips which are arranged on the mounting ring and distributed along the radial direction of the mounting ring and a jacking structure which is arranged at one end, far away from the mounting ring, of the rib strips, wherein the jacking structure is a cylinder the central axis of which is vertically arranged, a locating hole used for being embedded by the optical fiber preform from the lower end is formed in the upper part of the cylinder, an embedding sleeve used for replacement is arranged in the locating hole, the embedding sleeve is of a cylinder structure with the upper end open, and the lower end of the optical fiber preform is arranged in the embedding sleeve. By adopting the structure, the lower end of the optical fiber preform is arranged in the jacking structure, and the embedding sleeve is arranged in the locating hole of the jacking structure, so that optical fiber preforms with different specifications and diameters can be placed by adopting a manner of replacing the embedding sleeve.
Description
Technical field
The present invention relates to a kind of preform top support type clamping part, particularly relate to the preform top support type clamping part of a kind of compact construction, the use of adaptation plurality of specifications diameter optical fiber prefabricated rods.
Background technology
Preform is the starting material manufacturing quartzy series fibre, specifically, is the prefabricated big stick-means of intimidation for pulling optical fiber, is usually sintered by silica particulate material and forms.As is known in the industry, in the process by prefabricated big stick-means of intimidation and preform drawing optical fiber, need that fixed form is outstanding to be fixed on suspension system to hang by prefabricated big stick-means of intimidation.There is following shortcoming in the mode first adopted at present: 1, owing to employing the eccentric strap with lockhole, thus needs to make the end of preform caudal peduncle form a bulb being able to be limited by lockhole, so cause certain difficulty to the processing of preform; 2, limit in mechanism because preform is hung with eccentric state in preform, that is the longitudinal center of preform do not hang with quartz rod longitudinal center consistent, and because the bulb of preform caudal peduncle end is in unfixed free state, thus unavoidably exist to shake in the process of drawing optical fiber and put situation, even there is ball head and scurry out and accidents caused anxiety from the open slot of logical firmly lockhole.Consider that employing support positions clamping to preform for above problem, the preform diameter of right different size diameter does not wait, and the preform therefore adapting to plurality of specifications diameter on a set of equipment uses necessary.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of preform top support type clamping part, has compact construction, adapts to the feature of plurality of specifications diameter optical fiber prefabricated rods use.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of preform top support type clamping part, its innovative point is: described clamping part is arranged on the montant of vertically setting in suspension system, comprise the mounting ring be fixedly installed on montant, be arranged on described mounting ring along the radially-arranged some ribs of mounting ring, be arranged on the jacking structure away from described mounting ring one end on described rib, the right cylinder that centered by described jacking structure, axis vertical is arranged, on described right cylinder, right cylinder top is provided with the pilot hole embedded for preform lower end, be provided with in described pilot hole for being nested with of substituting, the described cylindrical structure be nested with as upper shed, be nested with described in the lower end of preform is placed in.
Preferably, the length of described pilot hole is 1/4 of jacking scantling length.
Preferably, described pilot hole is provided with the guiding rib being parallel to pilot hole bus, is nested with in the guide path of setting described in described guiding rib is embedded in.
Preferably, described pilot hole is at least provided with a described guiding rib, described in be nested with and be provided with the guide path consistent with described guiding rib quantity.
Preferably, gusset is provided with between described jacking structure and described rib.
The invention has the advantages that: by adopting said structure, preform lower end is placed in jacking structure, being nested with by arranging in the pilot hole in jacking structure, meeting inserting of the preform of different size diameter by the mode adopting replacing to be nested with.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of a kind of preform top support type of the present invention clamping part.
Fig. 2 is the A-A sectional view of Fig. 1.
In figure: 1-mounting ring, 2-rib, 3-jacking structure, 31-pilot hole, 32-guiding rib, 4-are nested with, 41-guide path, 5-gusset.
Embodiment
A kind of preform top support type clamping part of the present invention, clamping part is arranged on the montant of vertically setting in suspension system, comprise the mounting ring 1 be fixedly installed on montant, be arranged on mounting ring 1 along the radially-arranged some ribs 2 of mounting ring 1, be arranged on the jacking structure 3 away from mounting ring 1 one end on rib 2, the right cylinder that centered by jacking structure 3, axis vertical is arranged, on right cylinder, right cylinder top is provided with the pilot hole 31 embedded for preform lower end, be provided with in pilot hole 31 and be nested with 4 for what substitute, be nested with the cylindrical structure that 4 are upper shed, the lower end of preform is placed in and is nested with 4.By adopting said structure, preform lower end is placed in jacking structure 3, being nested with 4, meeting inserting of the preform of different size diameter by the mode adopting replacing to be nested with 4 by arranging in the pilot hole 31 in jacking structure 3.
In order to ensure strength of joint and connection reliability, the length of pilot hole 31 is 1/4 of jacking structure 3 length.In order to realize quick position guiding, pilot hole 31 is provided with the guiding rib 32 being parallel to pilot hole 31 bus, guiding rib 32 is embedded in the guide path 41 being nested with and arranging on 4.In order to improve positioning and guiding effect, pilot hole 31 being at least provided with a guiding rib 32, being nested with on 4 and being provided with the guide path 41 consistent with guiding rib 32 quantity.In order to strengthen strength of joint, between jacking structure 3 and rib 2, be provided with gusset 5.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention and non-limiting technical scheme, those of ordinary skill in the art is to be understood that, those are modified to technical scheme of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
