Abstract
The utility model relates to the a grinding machine, especially a grinding apparatus for optical fiber connector plug pin body ends. The utility model is characterized in that the machine frame 13 is equipped with the rotational motor 11, the revolving motor 12 and the driving grinding pan 14, which are controlled by the control system 15. The concentrator cramping apparatus 4 is sheathed on the positioning guide bar 8 and the cramping apparatus lifting rod 10 which are installed on the engine base. One end of the concentrator 3 on the concentrator cramping apparatus 4 connects with the ultrasonic transducer 7, and the other end connects with the contact pin body cramping apparatus 2 which is equipped with the contact pin body 1. The lower part of the cramping apparatus lifting rod 10 is equipped with the supporting spring 9, the upper part of which is equipped with the pressure adjusting spring 6 and the top of it is equipped with the compressor governor 5, which can adjust the contact force of the end face of the optical fiber contact pin body 1 and the grinding pan. The utility model realizes the multiple grinding of machinery and hyperacoustic. It reduces the bygone four grinding stages to two and enhances the grinding efficiency more than 10 times.
Description
Technical field:
The utility model relates to grinding machinery, especially a kind of optical fiber connector contact pin body end-face grinder that is applicable to.
Background technology:
After the assembling of optical fiber connector contact pin body and optical fiber, its end face must be the sphere of a complete connection, requires: 1. the optical fiber of end face can not evagination, can not be recessed; 2. end face is bright and clean; 3. the summit of end face spherical crown overlaps as far as possible with fiber optic hub; 4. the radius of curvature of end face is moderate.Above index directly influences the insertion loss and the return loss transmission performance of the joints of optical fibre.
Processing to ferrule of optical fiber connector body end face is to adopt traditional grinding-polishing technology at present, promptly using special fixture that pottery is inserted heart end face is pressed on the polishing disk that is lined with the silica gel cushion, grind sand paper on the cushion pad, under the grinding pressure effect, contact pin body 1 end surface grinding is become spherical shape; Grind sand paper and be generally diamond sand paper, along with replacing from coarse to fine is ground sand paper four times, its processing also will be experienced four procedures.This grinding technics grinding efficiency is low, and diamond sand paper consumption is big, grinds the cost height.
Summary of the invention:
The purpose of this utility model is: the weak point that overcomes existing grinding technics, and provide a kind of optical fiber connector contact pin body end-face grinder, to improve the grinding efficiency of optical fiber connector contact pin body end face, reduce manufacturing cost, satisfy the performance requirement of optical fiber connector.
The utility model optical fiber connector contact pin body end-face grinder is as shown in Figure 1: spinning motor 11 and the revoluting motors 12 installed in the frame 13 by control system 15 controls drive abrasive disks 14; Luffing bar cramp tool 4 is sleeved on the positioning and guiding bar of installing on the support 8 and anchor clamps elevating lever 10; Luffing bar 3 one ends on the luffing bar cramp tool 4 are connected with ultrasonic transducer 7, and the other end is connected with the contact pin body anchor clamps 2 that contact pin body 1 is installed; The bottom of anchor clamps elevating lever 10 is provided with support spring 9, and top is provided with pressure spring 6, and the top is provided with pressure regulator 5, with the end face of adjustment optical fiber contact pins body 1 and the pressure that contacts of abrasive disk.
The advantage and the good effect of the utility model optical fiber connector contact pin body end-face grinder fully show as:
1. realized machinery and ULTRASONIC COMPLEX grinding, made four road grinding steps in the past be reduced to twice, the time of per pass operation also shortens greatly, and total grinding efficiency improves more than 10 times;
2. ultrasonic grinding has reduced the pressure on workpiece 1 surface, has improved the speed of micro-cutting, makes the metamorphic layer of surface of the work reduce by one times, satisfies the transmission performance requirement of optical fiber connector.
Description of drawings:
Fig. 1: the utility model optical fiber connector contact pin body end-face grinder structural representation.
The specific embodiment:
Fig. 1 has described the working condition of optical fiber connector contact pin body end-face grinder.Ferrule of optical fiber connector body 1 (or claim workpiece) install luffing bar 3 front ends on anchor clamps 2, the concussion signal of telecommunication of the 20～30kHz that is produced by supersonic source and control system (not shown) 16 is converted to mechanical oscillating wave by the piezo-electric crystals in the transducer 7, through luffing bar 3, with the end face that vibrational energy is assembled, amplitude amplifies and be delivered to workpiece 1; The abrasive disk 14 that the contact of workpiece 1 end face is driven by motor 11,12, workpiece 1 end face is adjusted by look nut 5 and pressure spring 6 with the pressure size that contacts of abrasive disk 14; Abrasive media particulate high-speed high frequency on the abrasive disk 14 is impacted roll extrusion, cut workpiece 1 end face, makes process of lapping enter ductility territory grinding state, realizes efficient and high-quality attrition process.
The motion of abrasive disk 14 is compound motions that existing rotation also has revolution, workpiece 1 is a helical trajectory around revolution center with respect to the movement locus of abrasive disk 14, the speed of revolution and rotation is by grinding control system 15 (not shown)s, and motor 11,12 is regulated.
The major parameter of this device is as follows:
Ultrasonic power: 220V ± 20,50Hz;
Ultrasonic frequency: 26～31kHz;
Ultrasonic wave maximum power dissipation: 250W;
Abrasive disk rotational velocity: 0～120r/min (DC continuous speed regulation);
Abrasive disk revolution speed: 0～360r/min (DC continuous speed regulation).
