This moves up and down structure that drive mechanism uses to be vertically fixedly installed micro actuator 17 up and down, upper and lower micro actuator on knife rest 2
The 17 regulation crown is pushed away in the upper surface of guide pad 15.
The use process of the present embodiment is to adjust left micro actuator 62 manually first, pushes away the regulation crown of left micro actuator 62
Left grip slipper 41 moves, and adjusts the distance between left grip slipper 41 and cutter 3.Right micro actuator 64 is adjusted manually, makes right micro actuator
The 64 regulation crown pushes away right grip slipper 51 and moved, and adjusts the distance between right grip slipper 51 and cutter 3.And then adjust left clamping group
The length of the optical fiber clamped between part 42 and right clamp assemblies 52.Now, left spring 61 produces drawing to the left to left grip slipper 41
Power, right spring 63 produce pulling force to the right to right grip slipper 51.After adjusting, optical fiber is penetrated by left clamp assemblies 42, always
Penetrate into right clamp assemblies 52, and passed by right clamp assemblies 52, the left side that the left side of optical fiber is located in left clamp assemblies 42 is put
Put in the left locating slot 425 on plate 421, the right side of optical fiber is located at the right positioning on the right placement plate 521 in right clamp assemblies 52
In groove.After optical fiber places, left pressing plate 422 is placed to plate 421 to the left manually and rotated, left pressing plate 422 is inhaled with left placement plate 421
Close, now, the left side of optical fiber is located in the region that left holding tank 424 forms with left locating slot 425, and is compressed by left pressing plate 422
On left placement plate 421.Right pressing plate 522 is placed to the right to plate 521 manually to rotate, right pressing plate 522 is inhaled with right placement plate 521
Close, now, the right side of optical fiber is located in the region that right holding tank forms with right locating slot, and is pressed on the right side by right pressing plate 522 and puts
Put on plate 521.Now complete the firm clamping to optical fiber.
Then left micro actuator 62 and right micro actuator 64 are reversely adjusted respectively again, makes the regulation head of left micro actuator 62 and left clamping
Seat 41 separates, and the regulation head of right micro actuator 64 separates with right grip slipper 51, and now, left grip slipper 41 is applied by left spring 61
Pulling force to the left, and the power is passed to the optical fiber of retained part, that is to say, that the optical fiber of retained part receives left spring 61
The pulling force to the left applied, the pulling force to the right that right grip slipper 51 is applied by right spring 63, and the power is passed into clamping part
The optical fiber divided, that is to say, that the optical fiber of retained part also receives the pulling force to the right that right spring 63 applies simultaneously, therefore clamps
Partial optical fiber can be tensed by left clamp assemblies 42 and right clamp assemblies 52.Left grip slipper 41 and right grip slipper 51 are in left spring
Geo-stationary is kept in the presence of the reaction force of the optical fiber of 61 pulling force, the pulling force of right spring 63 and retained part.
After optical fiber is tensed, micro actuator 17 up and down is adjusted, knife rest 2 is moved with cutter 3 on vertical guide rod 16,
Upper-lower position of the knife rest 2 relative to guide pad 15 is adjusted, and then the depth that cutter 3 is cut into the cut of fiber outer surface can be adjusted
Degree.The present embodiment is set to be applied to cut various sizes of optical fiber, the cutting to various optical fiber has versatility, fits
It is wide with scope.
After the height of cutter 3 is adjusted, you can carry out cutting operation to optical fiber.When need to optical fiber carry out zero degree end face
When angle is cut, left clamp assemblies 42 are driven to be rotated by left driving motor 431, while right driving motor 531 drives right clamping
The synchronous rotary of component 52.
Promote guide pad 15 to be moved along guide rail 14 manually, cutter 3 is moved cutting to the front side of optical fiber from the rear side of optical fiber
Optical fiber, when the material of optical fiber is silica fibre, cutter 3 need to only cut out a bit of cut on the outer surface of optical fiber to be made
Silica fibre disconnects, and applies pulling force to the left to optical fiber in left spring 61, and right spring 63 applies pulling force to the right to optical fiber,
Optical fiber is set rapidly to be disconnected at cut.When the material of optical fiber is glass optical fiber, now cutter 3 is needed in the outer of glass optical fiber
Side face cuts out one and irises wipe trace, and when front side of the cutter 3 by being moved to optical fiber on rear side of optical fiber, optical fiber just rotates a circle, because
This can make cutter 3 cut out one on the outer peripheral face of optical fiber to iris wipe trace, also, glass optical fiber is in left spring 61 and right spring 63
Pulling force effect under rapidly disconnect, complete cutting.
It is more than 0 ° of end face for being less than 90 ° of end face angles with absolute value when needing to cut out as desired in the end face to optical fiber
When, after only left clamp assemblies 42 or right clamp assemblies 52 individually need to be rotated a certain angle, then by left clamp assemblies 42 and the right side
The synchronous rotary together of clamp assemblies 52, moves cutting, you can the section of optical fiber is cut out into gradient, meets to make by cutter 3
Use demand.
The present embodiment can also cut the soft glass optical fiber (multicomponent glass such as phosphate, germanate, silicate, bismuthates
Optical fiber).The present embodiment range of applicability is extensive, and cutting accuracy is high.
