Background technology
Whether grinding is a most important part in the joints of optical fibre production technology, and the quality of grinding can directly affect the docking performance of fiber connector, comprises whether docking is accurate, contact closely, and the docking performance affects again optical characteristics in the communication line transmission course.Because the impurity particle that exists part to grind away when grinding is attached on the grinding pad, some connector end face has cut and breakpoint after causing grinding, thereby affect the normal operation of optical fiber transmission line, this fiber connector belongs to substandard product, the regrind of need to doing over again.The grinding of doing over again mainly is to the adjustment of contact pin end face 3D parameter and the processing of problem end face.For the standard type fiber connector, do over again to grind and do not have difficult point, that is because be accompanied with positioning function on the standard type connector part, part and grinding clamp have universality, when therefore doing over again regrinding, connector can accurately be located according to location structure, the property of there are differences not, and for non-standard fiber connector, nonstandard structure designs according to customer requirement, and nonstandard this body structure of connector is without positioning function, owing to for ceramic contact pin jag processing length and inclination angle requirement being arranged when grinding, therefore when carrying out the regrind clamping, aim at original nonstandard angle of inclination very difficult, if twice is ground contact pin inclination angle misalignment, will cause contact pin length and angle can not reach requirement, present regrind method is manually to look for angle to carry out clamping by the workman, adopts visual means to aim at, and this method is not easy complete alignment angle, otherness is larger, grind angle and easily produce deviation, product percent of pass is low, and production efficiency is low.
Summary of the invention
The purpose of this utility model is exactly to solve the precise finiss that existing manually clamping carries out nonstandard fiber connector, otherness is larger, grinds angle and easily produces deviation, and product percent of pass is low, the problems such as production efficiency is low provide a kind of nonstandard fiber connector to grind the special tool die clamper.
Concrete scheme of the present utility model is: be designed with chuck, the center of chuck has installing hole, it is characterized in that: be designed with some mounting grooves at chuck around the installing hole periphery, the bottom surface of mounting groove is the inclined plane, the center of mounting groove has the contact pin perforation, is positioned at contact pin perforation both sides in the mounting groove and has two screw holes that are arranged symmetrically with; Adopt screw that a cover for seat is installed in corresponding each mounting groove, have two axial channel that are arranged symmetrically with on the sidewall of described cover for seat, the bottom of two guide grooves has the location hook groove that rotating Vortex is arranged, the bottom of cover for seat is provided with two mounting ears that are arranged symmetrically with, and has screw hole on each mounting ear; In each cover for seat, be fitted with a positioning sleeve, the lower end outer wall of described positioning sleeve is provided with two chucking lugs that are arranged symmetrically with, two chucking lugs cooperate with two location hook grooves in the cover for seat and are located by connecting, be designed with two axially directed inner planes that are arranged symmetrically with in the inner chamber of positioning sleeve, the top of positioning sleeve is provided with the catch spring top board; Spring and collet are housed in positioning sleeve, and this collet is provided with guide section, and the guide section outer wall is designed with two axially directed outerplanars that are arranged symmetrically with, and the guiding inner plane guiding in this guiding outerplanar and the positioning sleeve is connected; The chuck section of collet has 3-4 bar shaft orientation opening groove, and chuck section outer wall is shaped with screw thread, is fitted with nut.
Inclination angle design according to ceramic contact pin in the present joints of optical fibre is generally 8 ° or 11 ° two kinds, so its inclined bottom surface angle of the mounting groove on the chuck in the utility model is 8 ° or 11 °.Certainly, along with the development of technology, the design inclination angle of ceramic contact pin has new variation, and the utility model then can be according to the angle of inclination of the bottom surface of new design inclination angle design and installation groove.
In the utility model, for the clamping (installing the optical fiber of the joints of optical fibre) that makes things convenient for the joints of optical fibre, on the sidewall of positioning sleeve and collet, be positioned at same position and have the threading open slot that axially runs through.
Effect of the present utility model is: the utility model compact conformation, and a plurality of nonstandard connectors of simultaneously clamping of a sleeve clamp grind, and production efficiency is high, regrind clamping accurate positioning, fast, thoroughly overcome the angular deviation of regrind, product percent of pass is high.
