Description

A kind of novel optical fiber ferrule endface grinds implementation

Art

Patent of the present invention is a kind of new optical fiber ceramic lock pin end surface grinding mode, can improve ceramic insertion core grinding The qualification rate of apex offset and radius of curvature, reduces grinding cost, improves the efficiency of grinding.

Background technology

According to IEC standard, influence the correlative factor of the joints of optical fibre as follows：

Sequence number	Lock pin	Optical fiber	Connector grinding technics
				1	Concentricity	Concentricity	Radius of curvature
2	The endoporus angle of emergence（Opening angle）	Outside diameter（With lock pin inner hole degree）	Apex offset
				3	Outside diameter and roundness of external circle		Optical fiber height
4	Diameter of bore（With optical fiber fitness）

These three factors have to pass to radius of curvature, apex offset and concavo-convex amount for the grinding technics of connector and the equipment that uses Important relation.Whether radius of curvature, apex offset and concavo-convex amount these three factors are also qualified one joints of optical fibre of inspection Important indicator.Radius of curvature is generally described as lock pin axis to the radius of end face.Summit bias i.e. apex offset, refer to It is the axial line distance of the center with the sphere summit for obtaining of lock pin.Optical fiber height i.e. concavo-convex amount, refer to optical fiber and lock pin Between difference in height.

The lapping mode of the optical fiber ceramic lock pin that the current country uses is mainly using corner spring pressurization grinder grinding, The grinding circulation track of this grinder is the motion of circular loop, by the dual of the shuttling movement of abrasive disk and grinding clamp Motion is acted on, and ferrule endface is ground.

The grinding rubber cushion of grinder is quality of rubber materials, and abrasive sheet is pasted above, from coarse to fine according to grinding technics to be four and grind Grinding.Elastomeric material has the change of individual soft durometer with the change of grinding environment temperature, and general winter-spring season and summer and autumn be not using With the grinding rubber cushion of hardness.Grinding clamp is one piece of stainless steel plate, is punched according to certain rule above, the diameter of ceramic insertion core It is 2.499 ± 0.001mm, jack aperture is 2.515mm, and more bigger than lock pin, there is bayonet socket jack upper end, and lock pin is fixed. Grinding clamp is fixed on grinder with four spring pressure bars, and the motion Grinding clip with abrasive sheet during grinding has Individual to rock process, mutually motion is ground.

In use for some time, because jack plugs ceramic insertion core repeatedly, jack aperture can become larger grinding clamp, Fixation to ceramic insertion core will be affected.Other grinding clamp fix bar is revolved using spring pressurization and screw The mode for twisting fine setting is pressurizeed, and the growth of milling time can increase the fatigue strength of grinding Pressure-bar spring, and screw screws regulation pressure The control that power cannot be digitized, can only carry out experiment adjustment with feeling to operate.There is loss in grinding clamp and spring pressure bar The qualification rate of product can be caused afterwards to be reduced, and increased grinding cost and defect rate.

Ceramic insertion core relevant parameter is influenceed：

Project	Numerical value or explanation	Influence result	Lock pin is influenceed
				Grinding travel paths	Small circle is circulated, unchanged, can only a direction grinding	As the abrasion of holder aperture becomes big, eccentricity is received during grinding circulation Influence lock pin is rocked	Grinded curved surface radius
Grinding clamp fix bar uses spring pressurization, by the screw of upper end come Adjusting elasticity	Degree spring fatigue degree and screw regulation it is uncontrollable	Ceramic insertion core unbalance stress, consumes abrasive sheet	Apex offset

Refer to above table content.

The content of the invention

By the research to current lapping mode and grinder, according to the practical production experience of product, in order to improve ceramics Insertion core end face grinding qualification rate, my company redesigned a kind of novel optical fiber ferrule endface lapping mode and as Basis has manufactured grinder.This grinder not only increases the apex offset after optical fiber ceramic lock pin grinding and subsequent corrosion detection Percent of pass, also improves grinding efficiency, reduces grinding cost.

Patent of the present invention solves the technical scheme that technical problem used：Using three-shaft linkage mechanism to grind road Footpath is changed and adjusts, and the eccentric shaft motion of longitudinal upper strata is superimposed after the eccentric shaft of horizontal direction moves to certain distance, A grinding track for 8-shaped is formed after Union Movement.A screw axis are added in longitudinal direction bottom, is connected with screw axis Leapfrog motor, carry out the reciprocating motion in certain distance to 8-shaped grinding track, increase grinding efficiency.Use cylinder simultaneously To four fix bar pressurizations, air pressure regulator is installed additional, flexible fixation is carried out to grinding clamp using digitlization regulative mode.Four Fix bar by cylinder automatic lifting technology（The technology includes but not only including any of Pneumatic Transmission mode can realize four The technology that post rises）And realize automatically or semi-automatically adjusting the technology that abrasive disk spacing effectively controls spherical surface body curvature after grinding. Pressuring method is that cylinder pressurizes or the pressurization of servomotor adjust automatically, pressure is adjusted by air pressure regulator or automatically controlled Pressurization.

After eccentric wheel on longitudinal axis drives abrasive sheet to circulate one week under motor driving, the motor on triggering lateral shaft is opened Close, the eccentric wheel on lateral shaft starts to rotate, drive abrasive sheet motion, circulating is gone out at the point of contact of two circular loop rules It is dynamic, form a splay movement locus.The screw axis of longitudinal bottom drive the integral grinding driver element on upper strata, by jumping The driving for walking motor is moved according to the step pitch of advance 0.5mm per second, is triggering reverser when maximum is reached, and is transported backward It is dynamic, moved in circles with this, drive the region of the grinding unit change grinding on upper strata.The grinding track change of 8-shaped, can allow pottery Porcelain insertion core end face various aspects all obtain uniform effectively grinding.

Grinding clamp fix bar cylinder is pressurizeed by external stabilization source of the gas, then to be subject to air pressure regulator digitized Regulation, can keep four uniform forces of depression bar, reduce the abrasion to grinding rubber cushion.

Beneficial outcomes of the invention are, by the change and the change of grinding clamp fixed form of grinding track, improve light Fine ceramic insertion core radius of curvature percent of pass, reduces ceramic insertion core apex offset degree, improves the qualification rate of product, and reduction grinds to form This.
