Description
Technical field
The utility model relates to optical communication device fiber stub manufacture fields, and in particular to a kind of optical communication device is used up
Fine lock pin duplex concentricity processing unit (plant).
Background technique
Existing fiber ceramic insertion core concentricity processing is positioned with centre bore, and the mode for grinding outer diameter reduces concentricity,
Generally there are Double ejection pin apical pore positioning mode and centre bore threading two kinds of equipment principles of positioning mode.
As shown in Fig. 2, now threading positioning mode wears into the qin steel wire of 50 or so SC lock pin certain sizes a string, then will
On the fixed support frame with machine in the both ends of line, such a string of lock pins 10 are located at the centre of grinding wheel 20 and idle pulley 30, centreless knife plate
Top, idle pulley 30 advances when processing, lock pin 10 is pressed in the surface of grinding wheel 20 and because of the spin finishing of grinding wheel 20, and lock pin 10 is straight
Diameter reduces, and generates concentricity repair because hole positions grinding outer diameter to generate.After reparation is ground to target process dimension,
Turn lower process polishing outer diameter processing again.
Big using grinding wheel graininess in order to promote grinding efficiency, grinding wheel graininess is generally in 90~170#, to cause outer diameter ruler
Very little tolerance is big, face rugosity is thicker, and will there are the middle spare time of 0.008~0.012mm amounts on diameter dimension, and this degree
Allowance is after rear process polishing, the distribution relative distribution of concentricity.But since sand grains is thick, the processing for reducing polishing is stayed
Amount will cause the too small exception of outer diameter again.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of processing quality more preferably, processing it is same
Heart degree distribution more preferably optical communication device fiber stub duplex concentricity processing unit (plant).
The technical solution of the utility model is as follows:
A kind of optical communication device fiber stub duplex concentricity processing unit (plant), including being fixed on machine support frame can be into
The lock pin string that row moves back and forth, the upper end of the lock pin string along the extending direction rotary setting of the lock pin string have the first grinding wheel and
Second grinding wheel, first grinding wheel and the setting of the second grinding wheel parallel interval, the grinding wheel graininess of first grinding wheel is than described second
The grinding wheel graininess of grinding wheel is small, and the lower end of the lock pin string corresponds to first grinding wheel and the second grinding wheel is movably set with first respectively
Idle pulley and the second idle pulley, first idle pulley and the movement of the second idle pulley bottom and top feed, by first idle pulley by the lock pin
After the surface that string is pressed in first grinding wheel carries out spin finishing, allowance passes through second idle pulley for the lock pin before connecing
The surface that string is pressed in second grinding wheel carries out spin finishing.
Wherein, the grinding wheel graininess of first grinding wheel is 90~170 mesh.
Wherein, the grinding wheel graininess of second grinding wheel is 800~1000 mesh.
Wherein, first idle pulley and the second idle pulley are rubber material.
Wherein, the lock pin string is SC lock pin string or LC lock pin string.
Wherein, there are 0.008~0.025mm after the surface progress spin finishing that the lock pin string passes through first grinding wheel
Middle spare time amount.
Wherein, there are polishing allowances 0.002 after the surface progress spin finishing that the lock pin string passes through second grinding wheel
~0.006mm.
Compared with the existing technology, the utility model has the beneficial effects that: the utility model is ground due to concentricity reparation
When second step take thinner grinding wheel, so that processing quality is more preferably, concentricity, outer diameter tolerance all have compared with original processing mode
Larger promotion, polishing allowance is few in addition, reduces influence of the polishing process to concentricity, so that the concentricity distribution of processing is more
It is good.
Detailed description of the invention
Fig. 1 is the application principle schematic diagram of existing fiber lock pin；
Fig. 2 is that schematic illustration is ground in existing threading type concentricity reparation；
Fig. 3 is a kind of original of optical communication device fiber stub duplex concentricity processing unit (plant) provided by the utility model
Manage schematic diagram.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of optical communication device fiber stub duplex concentricity processing unit (plant), for processing optical fiber
Lock pin reduces concentricity in the way of grinding outer diameter, referring to Fig. 1, fiber stub, abbreviation ceramic contact pin, use optical fiber
There is a micropore at the cylindrical body of precise centering in connector plug, center, are used as fixed optical fiber.Optical fiber ceramic lock pin is logical applied to light
In the products such as light jumper, optical connector, optical module in news field.
Referring to Fig. 3, the optical communication device fiber stub duplex concentricity processing unit (plant) includes being fixed on machine support
The upper end of the lock pin string 1 that can be moved back and forth on frame, lock pin string 1 has first along the extending direction rotary setting of lock pin string 1
Grinding wheel 2 and the second grinding wheel 3, the first grinding wheel 2 and the setting of 3 parallel interval of the second grinding wheel, wherein the grinding wheel graininess of the first grinding wheel 2 is
90~170 mesh, the grinding wheel graininess of the second grinding wheel 3 are 800~1000 mesh, corresponding first grinding wheel 2 in the lower end of lock pin string 1 and the second sand
