Embodiment 1
[0023] Example as Figure 1 to Figure 4 As shown, a preform clamping device for an optical fiber drawing tower includes an upper plate 1 connected to the rod feeding mechanism, and a side plate 2 connected to the bottom surface of the upper plate. The side plates are two opposite pieces, and the side plate There are two pairs of parallel holes on the top, the upper pin rod 3 passes through the upper pair of holes 4 and passes through the corresponding upper pin hole 14 on the quartz handle 13 to lift the preform, and the lower pin rod 5 passes through the lower pair of holes 6 and pass through the corresponding lower pin hole 15 on the quartz handle.
[0024] Wherein, there is a gap between the lower pin rod and a pair of holes 6 below the side plate, and the purpose is to prevent falling when the pin hole above the rod handle breaks and play an insurance role.
[0025] Among them, the pair of holes above the side plate are notches, which ensure a large insertion distance and...

The invention discloses a clamping device for a precst rod of an optical fiber drawing tower. The clamping device comprises an upper plate connected with a precst rod conveying and feeding mechanism and a pair of side plates which are connected with the bottom surface of the upper plate and are oppositely arranged, wherein a space for accommodating a precst rod quart handle is reserved between the side plates; two pairs of holes are correspondingly formed in the side plates; one pin rod is matched with one pair of holes; each pin rod penetrates through the paired holes in the side plates and corresponding pin holes in the precst rod quart handle for lifting the precst rod; a jacking device for clamping is arranged at the lower part of each side plate and is used for jacking the precst rod quart handle after the precst rod is lifted. The clamping device disclosed by the invention has the beneficial effects that the problem of the troubling requirement on the stability of the precst rod in the clamping and wire drawing process in the industry is solved by adopting a simple and effective mode; a clamping force is reliable and the precst rod quart handle is not easy to damage; the requirement on the stability of the precst rod in the wire drawing process can be effectively guaranteed by smaller force; in addition, an overall structure is good in heat dissipating effect and no water cooling is needed.
Description
technical field [0001] The invention relates to an optical fiber drawing tower preform rod clamping device. Background technique [0002] The commonly used three-jaw chuck type clamping is not easy to control the force, and the jaws directly contact the surface of the preformed quartz handle, which is easy to cause damage such as cracks on the surface of the quartz handle, and it is very easy to cause the handle to break and cause the preform to fall. Property safety issues; most of this type of chuck structure has difficulty in heat dissipation, high working temperature, and prone to sticking and jamming. Regular maintenance such as disassembly and refueling is required, and maintenance and use are more troublesome. [0003] Other clamping devices that use preformed quartz handle perforation method, some use single hole method, lack of safety device when the single hole breaks; some use cross double holes, the processing angle of the quartz handle hole is not easy to guaran...
