When the horizontally arranged optical fiber tapering machine works, the tapering parts move horizontally in the graphite head, but under the high-temperature fire field of the graphite head, the tapering area in the horizontal state is affected by gravity, especially when the long tapering area is drawn, the tapering area in the molten state will sag radially due to gravity, which causes the outer periphery of the tapering area to deviate radially, affects the light beam output quality of the tapering part after tapering, and especially for some high-power (more than 2KW) and long tapering area laser energy device products, the existing tapering machine is difficult to meet the quality requirements.

The upper component drive nut block 565 is screwed onto the outer circumference of the upper component drive lead screw 564.

A pair of upper drive sliders 53 are connected to the bottom sides of the upper component mounting plate 13 respectively. The upper ring 131 of the upper component mounting plate 13 is sleeved on the outer periphery of the upper component drive nut block 565.

The limit cores are electrically connected to the upper component drive motor 561. One end of the stop is connected to the lower end of the upper component mounting plate 13. When the upper component mounting plate 13 drives the stop to move and triggers the limit cores, the limit cores send a signal to control the upper component drive motor 561 to stop running, preventing equipment damage.
