AI Technical Summary
In the existing technology, it is difficult to control the grinding amount in the grinding of the APC ferrule end face, resulting in inconsistencies in the size, angle and length of the forming surface, which affects the yield and production efficiency.
Design an APC end face forming fixture, which uses a combination of a grinding disc and a limiting pad. By controlling the vertical distance between the bottom surface of the grinding disc and the bottom surface of the limiting pad, the grinding amount can be precisely controlled to ensure the consistency of the end face angle and length of the insert.
This achieved consistency in the size and angle of the ferrule end face, improving yield and increasing production efficiency.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to ferrule processing frock technical field especially relates to a APC end face forming frock. BACKGROUND
[0002] The APC ferrule end face needs to be ground to 8 degrees, which makes most of the return loss be reflected to the cladding, does not interfere with the transmission signal and does not damage the laser source. At present, when producing the APC ferrule, the end face grinding is completed in the mode that the ferrule is fixed after the grinding disc and is manually ground to 8 degrees on the sandpaper, and the grinding amount is judged by relying on visual observation, and there are quality problems such as inconsistent size, angle and length of the formed surface and the ferrule, which easily lead to the increase of the 3D index and end face defective rate of the ferrule. SUMMARY
[0003] In view of the problem that the manual completion of the APC ferrule end face grinding is difficult to control the grinding amount in the prior art scheme, the utility model provides an APC end face forming frock.
[0004] The utility model provides the following technical scheme: an APC end face forming frock, including grinding disc, the top surface of grinding disc is provided with rotating shaft, the bottom surface of grinding disc is provided with limit pad, the projection of limit pad on grinding disc is located in the central part of grinding disc, and the bottom surface of grinding disc is parallel with the bottom surface of limit pad;The edge of the grinding disc is also provided with a plurality of insertion grooves, and an included angle is arranged between the central axis of the insertion groove and the bottom surface of the grinding disc.
[0005] Preferably, the grinding disc and the limit pad are both disc-shaped and coaxial, and the radius of the limit pad is smaller than that of the grinding disc.
[0006] Preferably, the plurality of insertion grooves are centrally symmetric about the central axis of the grinding disc.
[0007] Preferably, one side of the limit pad towards the grinding disc is provided with a positioning column, and the grinding disc is provided with a positioning groove matched with the positioning column.
[0008] Preferably, the included angle is 82 degrees.
[0009] The utility model has the advantages that: the limit pad is installed on the bottom surface of the grinding disc, the grinding amount is accurately controlled, the size, angle and length of the ferrule end face after grinding are consistent, the yield is improved, and the utility model is easy to operate and has high production efficiency.

[0013] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can implement the present application after studying the present application. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.
[0014] The present application provides an APC end face forming tool as shown in Figs. 1-2 The present application provides an APC end face forming tool as shown in
[0015] The grinding disc 10 can be disc-shaped, and the top surface thereof is provided with a rotating shaft 11, so as to facilitate transmission connection of the grinding disc 10 with a motor to drive the grinding disc 10 to rotate; the edge of the grinding disc 10 is further provided with a plurality of slots 12 for inserting the ferrules, in the embodiment, the slots 12 are matched with the front ends of the MT ferrules 30, the front ends of the MT ferrules 30 are inserted into the slots 12 and protrude to the bottom surface of the grinding disc 10, until the flanges at the tail portions of the MT ferrules 30 are clamped on the top surface of the grinding disc 10, and an included angle a is arranged between the central axis of the slot 12 and the bottom surface of the grinding disc 10, and the included angle a is 82° in the embodiment. Preferably, the plurality of slots 12 are symmetrically arranged about the central axis of the grinding disc 10.
[0016] The limiting pad 20 is arranged on the bottom surface of the grinding disc 10, and specifically, one side of the limiting pad 20 facing the grinding disc 10 is provided with a positioning column 21, and the grinding disc 10 is provided with a positioning groove matched with the positioning column 21, and the vertical distance between the bottom surface of the grinding disc 10 and the bottom surface of the limiting pad 20 can be controlled to effectively control the grinding amount. The limiting pad 20 can be disc-shaped, coaxial with the grinding disc 10, and the radius of the limiting pad 20 is smaller than that of the grinding disc 10, so that the projection of the limiting pad 20 on the grinding disc 10 is located in the center of the grinding disc 10, avoiding interference with the ferrules inserted on the edge of the grinding disc 10. The bottom surface of the grinding disc 10 is parallel to the bottom surface of the limiting pad 20, avoiding angle deviation during grinding.
[0017] The working process of the present application is as follows: firstly, the sandpaper is ensured to be parallel to the bottom surface of the grinding disc 10, a plurality of MT ferrules 30 are inserted into the slots 12 of the grinding disc 10 and fixed, then the bottom surface of the grinding disc 10 is aligned with the sandpaper to start rotating and grinding, until the sandpaper is attached to the limiting pad 20, the grinding is completed, the vertical distance between the bottom surface of the limiting pad 20 and the bottom surface of the grinding disc 10 is the predetermined ferrule length, and the end face angle of the ferrule is 8°, improving the consistency of the end face forming of the plurality of ferrules and the operability.
[0018] The above is one or more embodiments of the present application, which is described in more detail and in more detail, but cannot be understood as a limitation on the scope of the present application.
