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 preform rod clamping device for an optical fiber drawing tower, which includes an upper plate connected with a rod feeding mechanism, and a pair of oppositely arranged side plates connected with the bottom surface of the upper plate, and a preform rod is left in the middle of the side plates In the space for the quartz handle, there are 2 pairs of holes on the side plate, and each pair of holes is equipped with a pin rod. Rod; the lower part of the side plate is equipped with a clamping head device, and the head device withstands the quartz handle of the preform rod after the preform rod is hoisted. The beneficial effects of the present invention are as follows: adopting a simple and effective method solves the troublesome prefabricated rod clamping and wire drawing requirements for the stability of the rod; the clamping force is reliable and the quartz handle of the preformed rod is not easy to be damaged; The small force effectively guarantees the stability requirements of the rod in wire drawing; and the overall structure has a good heat dissipation effect without water cooling.
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...
