Semicircle groove 312a composition circular first crimping hole 313.The radius in the first crimping hole 313 is less than transversal at 74 crimping of aluminium set
The radius in face, to make the reduced cross-sectional area for the caudal peduncle 72 being located in aluminium set 74 after realizing crimping.
Lock pin Chuan Xian mechanism 4 includes the first plate 41, the second plate 42.16 lock pin location hole 411(numbers are set on the first plate 41
Amount can increase or reduce according to the actual situation), several optical fiber corresponding with lock pin location hole 411 are set on second plate 42 and are determined
Position hole 421.Guide rod 412 is arranged in 4 angles of the first plate 41 simultaneously；Pilot hole 422 is arranged in the corresponding position of second plate 42；It leads
It is slidably set on guide rod 412 to hole 422.
Drying adhesive mechanism 5 is a heating, drying equipment, glue when wearing fibre for drying on optical fiber 81.
The structure of secondary crimping mechanism 6 is consistent with a compression joint mechanism 3, for by caudal peduncle 72 and the aluminium set that is socketed in outside it
74, which carry out second, crimps.Secondary crimping mechanism 6 includes the second pressing element (not shown), and there is circular second crimping hole (not scheme
Show), and the radius of the second crimping hole (not shown) crimps the radius in hole 313 less than first, by the second pressing element (not shown)
Crimping after, caudal peduncle 72 is fitted closely with optical fiber jacket 82.
The working principle step of this system:
1, caudal peduncle 72 is fitted into first in the stepped hole 152b of pedestal 152 of plug core tail handle compression joint mechanism 1, then inserts lock pin 71
Enter 72 certain depth of caudal peduncle；By 151 sets of briquetting in each 152 upper end of pedestal, upper locating piece 151c is overlapped with lower locating piece 152c phase
Close, to guarantee that the position blind hole 151b and stepped hole 152b matches, make crimping more smoothly, accuracy more greatly, defect rate it is lower.
2, cylinder 14 generates thrust, pushes platen 142 and lock pin 71 and caudal peduncle 72 is made to realize crimping, after the completion of crimping,
Cylinder 14 retracts.2 pairs or more of lock pin 71 and caudal peduncle 72 can disposably be crimped in this way, improve the efficiency of crimping.
3, rotating operation table 12 rotates, and is located at next pedestal 152 for covering briquetting 151 under cylinder 14, repeats to walk
Rapid 2, it realizes serialization, mass crimping, improves efficiency.
4, several mechanical arms starting of lock pin protective case caudal peduncle assembling mechanism 2, by presetting, will crimp caudal peduncle 72
Lock pin 71 and stop 73 are inserted in protective case 75, and by 74 sets of aluminium set on caudal peduncle 72.
5,74 caudal peduncle 72 of aluminium set to connect together is placed on second mould 312 an of compression joint mechanism 3；Press-connection machine 33 opens
Dynamic, the first mould 311 is moved downward with push rod 332, is overlapped with the second mould 312, is crimped to aluminium set 74 with the progress first time of caudal peduncle 72,
Make the reduced cross-sectional area of caudal peduncle 72, reduce the space that may deviate when wearing fibre, so that optical fiber 81 is inserted into lock pin 71 more smoothly and quasi-
Really, the risk for reducing fibre-optical bending or even fractureing, improves certified product rate.
6, lock pin 71, the light on the second plate 42 are placed in the lock pin location hole 411 on 4 first plate 41 of lock pin Chuan Xian mechanism
Placed in fine location hole 421 and peel off optical fiber jacket 82, after lock pin 71 and optical fiber 81 are all placed on corresponding position, using manually or
Mechanical mode moves down the second plate 42 along guide rod 412, is inserted into optical fiber 81 on lock pin 71, and glue is completed to insert on point
Core wears fine step.A number of lock pin can once be completed in operation in this way and wear fine work, improve life
The efficiency of production, reduces workload.It decreases simultaneously and wears fine bring error by hand, to be further reduced the bending of optical fiber 82
The risk of deformation improves concentricity.
7, it is toasted in drying adhesive mechanism 5, makes that the glue solidifies.
8,74 caudal peduncle 72 of aluminium set to connect together is placed in secondary crimping mechanism 5, aluminium set 74 and caudal peduncle 72 is carried out
Second of crimping.Since the radius of the second crimping hole (not shown) is less than the radius in the first crimping hole 313, crimped by second
Afterwards, the sectional area of caudal peduncle 72 further reduces, and final caudal peduncle 72 is fitted closely with optical fiber jacket 82, completes the group of fiber stub
Dress.
Based on the above description of the preferred embodiments of the present invention, through the above description, related personnel completely can be with
Without departing from the scope of the technological thought of the present invention', various changes and amendments are carried out.The technical scope of this invention
It is not limited to the contents of the specification, it is necessary to determine the technical scope according to the scope of the claims.
