Abstract
The utility model relates to a dedicated device used for grinding and polishing the pipe, in particular to a grinding device used for the ceramics lock pin bore of the optical fiber connector. The grinder of ceramic core internal hole for light-guide fibre connector is characterized in that mandrel 5 of two gears 12 are respectively provided with reel 7; wire 2 is penetrated into a ceramics lock pin 20, and is sheathed with a clamping apparatus 11 in a hollow spindle 10 of an electric rotary motor 1; one head of the wire passes through a grinding wheel 3 which is provided with grinding fluid 9, the wire through a tension pulley 4 is connected with a reel 7, and other head of the wire through the grinding wheel 3 and the tension pulley 4 is connected with the reel 7. As the spindle 10 of the electric rotary motor 1 is connected with the clamping apparatus 11 for entirety, the middle part of the grinder has no gearing link; the grinder of ceramic core internal hole for light-guide fibre connector has high rotary speed, small oscillation, and high efficiency; grinding the ceramics lock pin 20 has favorable quality; the grinder of ceramic core internal hole for light-guide fibre connector can satisfy the requirement for the fiber optic connector of the optical fiber communication system.
Description
Technical field:
The utility model relates to the special equipment that is used to manage inner grinding and polishing, especially a kind of lapping device that is used for the ceramic insertion core endoporus of optical fiber connector.
Background technology:
Fig. 2 has showed the structure and the installation situation of optical cable 23 (being fibre-optic bundle) connector: adapter 21, interior interspersed installation ceramic insertion core 20; The external diameter of ceramic insertion core 20 is 2mm, and internal diameter is 125 μ m, and optical cable 23 is installed in it.This joints of optical fibre consumption in optical fiber telecommunications system is many, is the logical device of crucial passive light that quality is had the greatest impact.And the loss of connector is depended on optical fiber 22 and is cooperated, is the vital part ceramic insertion core 20 of optical fiber 22 location, therefore requires the internal-external circle concentricity error of ceramic insertion core 20 must be less than 0.1 μ m.
The endoporus of ceramic insertion core 20 is draw ratios up to 50 elongated micropore, the requirement on machining accuracy height, and it is highly difficult fine parts manufacturing technology that ceramic insertion core 20 endoporus grind.
At present, generally adopt inside diameter grinder to grind.Specifically: ceramic insertion core 20 is fixed on the anchor clamps of grinder, motor drives anchor clamps by transmission mechanism and rotates, the grinding silk with gradient of etch is in advance passed from the endoporus of ceramic insertion core 20, when grinding, to stick to lip-deep abrasive material (generally being bortz powder) suspension by the grinding silk brings in the hole as abrasive media, rotation along with anchor clamps, grind silk and in endoporus, move back and forth, make the abrasive particle that sticks in the lapping liquid that grinds on the silk carry out grinding ceramic insertion core 20 endoporus.The problem that this processing method exists is, because the rotation of workpiece is driven by transmission mechanism, the vibration of workpiece is bigger, though rotating speed is not high, the machining accuracy difficulty is big, inefficiency.
Summary of the invention:
The purpose of this utility model is that design optical fiber connects ceramic insertion core 20 endoporus high speed lapping devices, not only can significantly improve grinding rate and operating efficiency, and can carry out the adjustment and the test of technological parameter on a large scale, optimize the matching technique parameter, guarantee the precision in ceramic bar in-core hole, satisfy in the optical fiber telecommunications system requirement the joints of optical fibre.
The technical solution of the utility model is:
The lapping device of ceramic insertion core 20 endoporus of optical fiber connector is by work housing 6, and direct current electric rotating machine 1, stepper motor 13, compositions such as straining pulley 4 and abrasive wheel 3, its stepper motor 13 drive cog belt 8 and connect four gears, 12 formation transmission integral body; On the mandrel 5 of two gears 12 reel 7 is installed separately; Wire 2 penetrates ceramic insertion core 20, and is set in the anchor clamps 11 in the hollow spindle 10 of electric rotating machine 1; Its abrasive wheel 3 by filling lapping liquid 9 joins through straining pulley 4 and reel 7, and the other end is connected on the reel 7 through abrasive wheel 3 and straining pulley 4 equally.
Advantage of the present utility model demonstrates fully:
1. since the main shaft 10 of electric rotating machine 1 be integrated with work piece holder 11, transmission link in the middle of not having, so rotating speed height, vibrate little, the efficient height, the Grinding Quality of ceramic insertion core 20 endoporus is good, satisfies in the optical fiber telecommunications system requirement to the joints of optical fibre.
2. electric machine main shaft speed is up to 20000r/ming, can carry out the technological parameter adjustment and the test of wide region, the related law of technological parameter and machining accuracy in grasp ceramic insertion core 20 process; The optimum Match that helps optimal processing parameter.
Description of drawings:
Fig. 1: the structural representation of ceramic insertion core of optical fibre connector 20 endoporus lapping devices;
Fig. 2: the structure of optical connector and the situation of installation schematic diagram.
The specific embodiment:
Regulate following parameter:
A. direct current electric rotating machine 1 speed 0～20000r/min;
B. stepper motor 13, i.e. wire 2 reciprocating speed, distance;
C. straining pulley 4 is regulated the tension force of abrasive metal silk 2.
Lapping liquid adopts and is made into different grain size, different viscosities, the diamond abrasive pastes of different hardness.
Stepper motor 13 drives gear 12 rotatings, and the transmission integral body by other three gears 12 and cog belt 8 formation back and forth movements can make reel 7 rotatings, realizes that coming and going of wire 2 is mobile; Wire 2 penetrates a plurality of ceramic insertion cores 20, and together puts into hollow anchor clamps 11, and anchor clamps 11 are directly packed in the direct current generator 1 of being with hollow hole; Wire 2 one ends on the reel 7 on the left side, by straining pulley 4 abrasive wheels 3 on the left side, the abrasive wheel 3 on anchor clamps 11 and the right, straining pulley 4 is again on the reel 7 on the right.
Direct current generator 1 drives ceramic insertion core 20 spin finishings, and stepper motor 13 drives wire 3 and moves back and forth, and brings lapping liquid 9 into ceramic insertion core 20 endoporus by abrasive wheel 3 and back and forth grinds.
