Fixture.
Background technique
Fiber optic conduction laser is usually utilized in addition to space passes light for the equipment or system using laser as light source,
At this moment it just needs using optical fiber connector, such as SMA905.The manufacture craft of SMA905 is quite mature, grinds together wherein having
Grinding process is ground to optical fiber together with lock pin after optical fiber penetrates lock pin, filling adhesive solidification.Optical fiber in the market
Grinder is similar, and grinding clamp used in conjunction with is direct insertion structure mostly, and passes through spring loaded mode
Lock pin is fixed.Good end face effect is ground in this grinding clamp cooperation grinding function, reaches the production of SMA905
It is required that.
SMA905 is the connector of simple optical fiber, now more and more extensive with laser use scope, one kind occurs
Using needing for the output light of multi-station laser to be gathered together.A kind of optical fiber connector is just needed accordingly, and one end has very
Multiple-limb is separately connected every laser, and the other end is then to be bundled together these optical fiber collection.The branch end of this connector can
With according to the manufacture craft of SMA905, however fiber optic bundle end, due to being Multi-core number, manufacture craft needs improve to some extent.For light
The grinding technics of fine Shu Duan is by all optical fiber according to certain regularly arranged, after penetrating lock pin, filling adhesive solidification, to light
Fine Shu Liantong lock pin is ground together.The grinding clamp of SMA905 cannot be used since the aperture of pedestal is too small, then only right
The aperture of pedestal is expanded according to the size of fiber optic bundle end lock pin.Fiber optic bundle end face is ground using this grinding clamp
When, it is found that fiber optic bundle since core number is more, size is big, needs lock pin grinding cutting amounts more more than single fiber, and existing Grinding clip
Tool is since using spring loaded mode, cushion block therein limits the amount of stretching under lock pin, so that the grinding of fiber optic bundle lock pin can
Cutting output is inadequate, and the hair of grinding situation can not be continued by causing the grinding quality of fiber optic bundle end face not meet given requirements also but with regard to this
It is raw, and spring loaded mode is no longer able to the lock pin of fixed large-scale optical fiber beam to achieve the purpose that control lock pin grinding.
In addition, occurring the case where fiber optic bundle lock pin shaking during grinding, enough supports can not be provided to the lock pin of fiber optic bundle
Power.

Degree.
Compared with prior art, the utility model has the beneficial effects that
A kind of grinding clamp suitable for fiber optic bundle end face of the utility model, devises the pedestal and locking member of separation, bottom
Limiting through hole on seat being capable of perfect adaptation fiber optic bundle lock pin；Locking member is added using the structure of three feet pressurization instead of Conventional springs
The structure of pressure, so that locking member is more firm to the fixation of fiber optic bundle lock pin, balanced, and the locking member of this structure no longer needs
The cushion block for wanting spring-weighted structure substantially increases lock pin grinding machinable amount；There is fine thread hole on locking member simultaneously, cooperates
Bolt of serration is the grinding cutting amount for accurately controlling fiber optic bundle lock pin by rotation bolt of serration, and changing can not originally control
The problem of lock pin grinding cutting amount processed；By suitably increasing the thickness of pedestal, pedestal is inserted to large-sized fiber optic bundle
Core provides enough support forces, improves the case where lock pin shakes in process of lapping.Compared with existing grinding clamp, this is used
A kind of grinding clamp suitable for fiber optic bundle end face of utility model is ground, and fiber optic bundle lock pin is more steady, fiber optic bundle end face
Grinding quality it is more preferable, yield rate is higher, reduces the cost of raw material.The utility model can be applied to large-scale optical fiber Shu Duan
In the grinding process in face, practical value with higher.

Specific embodiment
Referring to Fig. 1-2, a kind of grinding clamp suitable for fiber optic bundle end face, including pedestal 1 and locking member 2 is set on pedestal 1
It is equipped with a central through hole 1.1 and multiple limiting through hole 1.2；Locking through-hole 2.1, fine thread are provided on the locking member 2
Hole 2.2 and bolt of serration 2.3,2 side of locking member are provided with three groups of minor thread holes 2.4 and stove bolt 2.5.
The diameter of the limiting through hole 1.2 is slightly larger than the outer diameter of fiber optic bundle lock pin, perfect can be adapted to fiber optic bundle lock pin, i.e.,
Fiber optic bundle lock pin can in limiting through hole 1.2 transverse shifting, and cannot vertically move, and suitably increase the thickness of pedestal 1,
Ensure that pedestal 1 is capable of providing enough support forces to large-sized fiber optic bundle lock pin, has evaded to fiber optic bundle end surface grinding process
The occurrence of middle fiber optic bundle lock pin shakes；The corresponding locking member 2 of each limiting through hole 1.2, between adjacent limiting through hole 1.2
It maintains a certain distance, it is ensured that being capable of combination locking part 2.
The locking member 2 is the cylindrical body that edge connects a cuboid, and upper and lower surfaces flush, and locks through-hole
2.1 are located at the cylinder center of cylindrical body, and the diameter of locking through-hole 2.1 is greater than the diameter of 1 upper limit through-hole 1.2 of pedestal.Three phases
Same minor thread hole 2.4 is evenly distributed on the side of cylindrical body, and on a horizontal plane, between adjacent minor thread hole 2.4
Angle is 180 °, and the length for the stove bolt 2.5 being adapted to therewith is greater than the depth of minor thread hole 2.4, protrudes into lock in fiber optic bundle lock pin
By screwing three stove bolts 2.5 after tight through-hole 2.1, so that it may form the pressurization of three feet to fixed fiber optic bundle lock pin.The closely-pitched
Threaded hole 2.2 is located at the planar central of cuboid, and the length for the bolt of serration 2.3 being adapted to therewith is greater than fine thread hole 2.2
Depth, after the locking through-hole 2.1 that fiber optic bundle lock pin is protruded into locking member 2 is fixed, then by fiber optic bundle lock pin together with locking member 2
Limiting through hole 1.2 on inserted base 1, the at this time bolt of serration 2.3 on locking member 2 used in precession, so that it may adjust fiber optic bundle and insert
The relative position of core and pedestal 1, and then can control the cutting output of fiber optic bundle lock pin during the grinding process.
Working principle:
Firstly, pedestal 1 is placed on optic fiber polishing machine, fiber optic bundle lock pin is protruded into locking member 2, does not have to screw lock at this time
Three stove bolts 2.5 on tight part 2, but by fiber optic bundle lock pin together with the limiting through hole on 2 inserted base 1 of locking member
1.2, so that fiber optic bundle lock pin is touched the pouncing paper of optic fiber polishing machine；Then, the distance between locking member 2 and pedestal 1 are adjusted, is made
There are a little spaces between the two, and screw in the bolt of serration 2.3 on locking member 2, until touching pedestal 1, screw locking at this time
Three stove bolts 2.5 on part 2, fix fiber optic bundle lock pin；Finally, placing the counterweight of appropriate weight on locking member 2
Start the grinding operation of progress fiber optic bundle end face, and optical fiber is accurately controlled by precession bolt of serration 2.3 during the grinding process
The cutting output of beam lock pin, until the grinding quality of fiber optic bundle end face meets the requirements.
