When docking the optical fiber preform, the reciprocating screw moves to drive the oil outlet roller to rotate, so that the lubricating oil can be transported out of the oil tank through the groove of the oil outlet roller, and then the lubricating oil can be sprinkled on the surface of the bidirectional threaded rod, so that the three-jaw chuck table can be more accurate in the process of docking the optical fiber preform. At the same time, the stirring plate will contact the stopper during the movement, so that the stirring plate will rotate, so that the oil in the oil tank can be stirred in a low temperature environment to avoid solidification of the oil in the oil tank that causes the oil to be unable to flow out, thereby affecting the accuracy of the device during use.

[0010] 3. The optical fiber preform docking equipment operates in coordination among the heat preservation cover, the notch plate 1, the notch plate 2, the triangular plate, the chute block, the fixed shell, the elastic telescopic plate, and the plug plate.
