On pedestal 301.
In the space that four pillars 11 that guide holder 30 is located at frame body 1 are surrounded, the corner location of guide holder 30 is equipped with phase
For the notch answered to avoid four pillars 11, the position that guide pin 5 is corresponded on guide holder 30 is equipped with perforation, consolidates at 30 perforation of guide holder
Surely there is linear bearing 7, guide pin 5 is installed in the inner hole of linear bearing 7, and the guiding of linear bearing 7 is more accurate, it is ensured that guide holder
30 are in a horizontal position always during moving up and down along guide pin 5, ensure that the abrasive disk 31 of grinding assembly 3 in grinding
Upper abrasive sheet the optic fibre end of downside that expose fiber clamp 2 can be carried out stablizing grinding, prevent because of abrasive disk 31 not
Level leads to optic fibre end is finally ground that there are mismachining tolerances.It is arranged with helical spring 6, spiral shell respectively on four guide pins 5
The both ends of rotation spring 6 press against on the opposing end surface of guide pin fixed block 50 and linear bearing 7, pass through the elasticity of helical spring 6
Press effect enables guide holder 30 and grinding assembly 3 to be automatically moved up, and realizes elastic grinding.
As shown in Figure 4 and Figure 6, the downside that motor 32 and position rotaring motor 34 are each attached to guide holder 30 is ground, and in order to
Reduce optical fiber into the volume of terminal, in the present embodiment, grinding motor 32, position rotaring motor 34, lifting motor 4 and helical spring are horizontal
Arrangement, takes full advantage of the space between pedestal 10 and guide holder 30, reduces optical fiber as far as possible into the volume of terminal.Other are implemented
In example, above-mentioned layout can change as needed, for example, grinding motor can be arranged at the center on the upside of guide holder, or
The downside etc. of guide holder is arranged in lifting motor by person.
Rotate and reverse realization and loosen connecting rope 40 upwards and pull down by controlling lifting motor 4 and is close to splicing
40.Guide holder 30 can be driven up and down, realize separating or contacting up and down for abrasive sheet and optic fibre end on abrasive disk 31
Work.It is set on abrasive disk 31 in the present embodiment there are four ground station, is equipped with abrasive sheet, this implementation in each ground station
The installation of abrasive sheet for convenience, abrasive disk 31 are equipped with abrasive sheet locating slot in example, when optic fibre end replaces ground station,
After optic fibre end is separated with abrasive sheet, abrasive sheet locating slot should be left, avoids abrasive sheet locating slot and optical fiber in replacement process
End is collided with, and certainly, in other embodiments, being higher than on abrasive sheet locating slot or abrasive disk in abrasive sheet apical side height does not have
When abrasive sheet locating slot is arranged, abrasive sheet is left in optic fibre end guarantee in replacement process.Grinding in front on abrasive disk
Grinder position is corase grinding station, is fine grinding station in subsequent station, and there are four the abrasive disk settings in the present embodiment, Ke Yixuan
It selects therein at least two and carries out grinding operation.The setting of station quantity can according to need adjustment in other embodiments, such as
It can be two, three, five etc..
