When the optical axis with longer length is semi-finished and finished (more than 400 mm), the clamping mode is a one-clamping-one-ejection mode, namely, one end of the optical axis is arranged at one end of a chuck and is stably placed, the other end of a workpiece is pulled to be aligned, and a tailstock is operated to enable the center of the tailstock to be ejected into a central hole of the optical axis; before this process, need fall the optical axis between chuck and the tailstock with the overhead traveling crane earlier, when hoist and mount, the overhead traveling crane need use the lifting rope to tie up the optical axis when hoist and mount earlier, this kind of mode that adopts the lifting rope can't guarantee that the both ends of optical axis are on same axis, leads to optical axis and chuck axis to appear the deviation, and the tailstock top can't stretch into in the optical axis centre bore after pressing from both sides tight. The length allowance of the optical axis is smaller, so that the clamping positions are fewer, and when the optical axis of the sling is loosened and clamped, the optical axis is influenced by gravity and is easy to fall off. Therefore, the center frame is required to be used for auxiliary support during clamping, and the shaft is prevented from falling under the action of gravity. The lifting and lowering of the center frame are required to close the protective door, and when the overhead travelling crane is used for hoisting, the protective door is required to be bound by a hoisting belt, so that the protective door cannot be closed, and the center frame cannot be used for auxiliary support. When the processing weight is lower than 20 kg of optical axis, the crane is not needed to be used for hoisting, the clamping is directly carried manually, the problems in the prior art exist during clamping, the protective door cannot be closed before clamping, and the center frame cannot be started.

In summary, the existing clamping mode cannot meet production requirements, and the existing clamping mode can only be used for lifting through an overhead crane, or is used for manually carrying, so that potential safety hazards exist in production, longer auxiliary clamping time is needed in the clamping process, and production efficiency is low.
