Description

一种非标光纤连接头研磨专用工模夹具 A non-standard fiber optic connector polishing dedicated tooling fixture

技术领域 FIELD

[0001] 本发明涉及光通信零部件的加工工装模具,尤其是一种非标光纤连接头研磨专用工模夹具。 [0001] relates to optical communication processing parts of the tooling of the present invention, in particular a non-standard fiber optic connector polishing dedicated mold fixture.

背景技术 Background technique

[0002] 研磨是光纤连接器生产工艺中最重要的一部分,研磨的质量能直接影响光纤连接头的对接性能,包括对接是否精准,接触是否紧密,对接性能又影响通信线路传输过程中的光学特性。 [0002] The milling is a fiber optic connector production process is the most important part of the quality polishing can directly affect the docking performance of fiber optic connectors including mating if accurate, the contact is close, the docking performance and affects the optical characteristics of the communication line during transmission . 由于研磨时存在部分研磨掉的杂质颗粒附着在研磨垫上,造成研磨后有些连接头端面有划痕和破点,从而影响光纤传输线路的正常工作,这种光纤连接头属于不合格产品,需要返工二次研磨。 Due to the grinding portion ground off foreign particles attached to the polishing pad, some connector end surface scratches caused by the polishing and break point, thus affecting the normal operation of the optical fiber transmission line, such an optical fiber connector are substandard products, we need to rework regrinding. 返工研磨主要是对插针端面3D参数的调整以及问题端面的处理。 Rework polishing end faces of the pin is mainly to adjust the parameters of the 3D process and the problems of the end face. 对于标准型光纤连接头,返工研磨不存在难点,那是因为标准型连接头零件上附带有定位功能,零件及研磨夹具具有普适性,因此返工复磨时,连接头能根据定位结构精确定位,不存在差异性,而对于非标准型光纤连接头,非标的结构根据客户要求而设计,非标连接头本身结构不带有定位功能,由于研磨时对于陶瓷插针突出端加工长度和倾斜角有要求,因此在进行二次研磨装夹时,要对准原有的非标倾斜角度十分困难,如果两次研磨插针倾角对不准,将会导致插针长度和角度不能达到要求,目前的二次研磨方法是由工人手动找角度进行装夹,采用目视方法对准,这种方法不容易完全对准角度,差异性较大,研磨角度容易产生偏差,产品合格率低,生产效率低。 For standard optical fiber connector, rework polishing absence difficulty, because it is included with the standard connector part positioning function, and the polishing jig parts is universal, so when re-grind rework, can pinpoint connector positioning structure according to , there is no difference, but for the non-standard fiber optic connectors, non-standard structure according to customer requirements and design, the structure itself is non-standard connector without a positioning function, since the protruding ends of the ceramic pins when the inclination angle and the length of grinding is required, therefore during the second grinding fixture to align the existing non-standard tilt angle is very difficult, if not allowed to dip twice grinding pin, the pin will cause the length and angle can not meet the requirements, the current secondary polishing method is to find a worker manually clamping angle, aligned by visual methods, this method is not easy to completely misalignment angle, larger differences, tends to vary the grinding angle, pass rate of products, the production efficiency low.
