Clamping part for novel optical fiber preforms

Abstract

The invention discloses a clamping part for novel optical fiber preforms. The clamping part is characterized in that the clamping part is arranged on a vertical rod vertically arranged in a suspension device and comprises a mounting ring fixedly arranged on the vertical rod, a plurality of rib plates connected with the mounting ring and distributed in the radial direction of the mounting ring, and positioning rings arranged at the ends, far from the mounting ring, of the rib plates; the side surface parts of the optical fiber preforms are arranged in the positioning rings; the rib plates are composed of first rib plates connected with the mounting ring and second rib plates connected with the positioning rings; the second rib plates are arranged on the first rib plates in a screw-thread fit manner. With the adoption of the structure, the rib plates adopts the manner that the first rib plates are in screw-thread fit with the second rib plates, the centre distances between the positioning rings and the mounting ring can be changed through changing the screw-thread fit lengths of the first rib plates and the second rib plates, so that the effect of telescopic adjustment is realized and thus positioning and clamping requirements of the optical fiber preforms of different specifications and diameters are met.

Description

technical field [0001] The invention relates to a novel clamping part for an optical fiber preform, in particular to a compact and scalable novel clamping part for an optical fiber preform. Background technique [0002] Optical fiber preform is the raw material for manufacturing quartz series optical fiber, specifically, it is a prefabricated rod used to draw optical fiber, usually sintered from silica granular material. As known in the industry, in the process of drawing an optical fiber from a prefabricated rod, that is, an optical fiber preform, it is necessary to suspend and fix the prefabricated rod on a suspension device in a suspended and fixed manner. There are following disadvantages in the mode that adopts earlier at present: 1, owing to have used the eccentric ring that has lock hole, thereby need to make the end of optical fiber preform tail handle form a ball head that can be limited by lock hole, so the processing of optical fiber preform 2. Because the optica...

There are following disadvantages in the mode that adopts earlier at present: 1, owing to have used the eccentric ring that has lock hole, thereby need to make the end of optical fiber preform tail handle form a ball head that can be limited by lock hole, so the processing of optical fiber preform 2. Because the optical fiber preform is hung on the optical fiber preform limiting mechanism in an eccentric state, that is to say, the longitudinal center of the optical fiber preform is not consistent with the longitudinal center of the quartz hanging rod, and because the optical fiber preform The ball head at the end of the tail handle is in an unfixed free state, so it is unavoidable to wobble during the process of drawing the optical fiber, and there is even the risk of accidents caused by the ball head jumping out of the opening slot that passes through the lock hole
