摘要

光纤连接器是用于实现系统中设备与设备、设备与仪表、设备与光纤、光纤

与光纤之间的非永久性固定连接，是光纤通信系统中各种装置连接必不可少的器

件，也是目前使用量最大的光纤器件，因此，光纤连接器加工受到工程界和学术

界广泛关注．随着对光纤连接器性能要求的不断提高和应用数量的不断增加，现

有的光纤连接器加工设备及加工技术越来越难以满足其发展要求。而我国对光纤

连接器端面加工中的关键设备光纤连接器端面研磨机的研发与国外存在很大差

Abstract

Fiber connector,used for the non-permanent rigid connection in the fields of

equipment to equipment,equipment to instrument，equipment to fiber and fiber to fiber,

is the absolutely necessary device for the connection of different kind of apparatus in

the fiber communication system，which is widely used currently．Therefore，more and

more people pay attention to the equipment and the technique used in machining the

fibercoBnecIf．or．Alongwiththecontinuously improvingrequirementsoffiberconnector

peffommce and the increasing number of applications，existing equipment and

technology are more and more difficult to satisfy the requirements of fiber connector．

Howls,oct,there is a big gap between China and foreign countries in the research ofkey

equipments in end-face prot∞s$．So it is significant to manufacture a kind of fiber

connector end·face tapping machine with the proprietary intellectual property rights，

which will promote the development of fiber conneetor end-face machining and

precision／super-precision machining technology ofour country．

The function,application,type classification，technical index standards and other

problems of fiber connectof are introduced in detail．the effects of fiber enmle虻1．or

end-face processing mechanism,processing technology and material removal model on

mlrfat∞quality of fiber connector are analyzed；Witll respect to the fiber connector

end-face lapping machine．based on the survey of current status of aboar也a kind of

planetary fiber connector end·face lapping machine with double drive and two degrees

of freedom is developed,the integrated 3d-model of lapping machine is built诵th UG．

and the designs of pneumatic system and electronic control system黜accomplished；

The grinding traces ofplanetary fiber connector end-face lapping machine are simulated

using virtual prototype technology and ADAMS，the effects of three major parameters

including the ratio of revolving alto rotating velocity and self-rotating velocity，the

length of revolving arm,the distance between center poim of fiber enmllxfllor end-face

and inner gear on grinding Iraces change and grinding quality a坞扣mIy刁ed’when

achieving the ideal grinding tl'aees，the combination of the major parameters above is

determined,and the grinding traces which meet requirement of fiber connector end-face

processing arc achieved；According to the effect of[Finding traces and velocity offiber

connector end-face lapping machine which is developed in the paper,the velocity

ranges of motors which driving the revolving alTn and inner gear are determined；The

experimental platform for researching on the experiment of fiber connector end-face

processing and technology is provided by the model machine manufacturing．

The research oftechniques and machine for machining fiber connector end-face in this

paper is contributed to promote the quality of fiber connector end-face and the

performance offiber connector in practical processing．
