Technical Field

[0001] The utility model relates to the technical field of FA jumper processing, and relates to an FA grinding weight-reducing device. Background Art

[0002] An FA jumper is a high-performance connector used in optical fiber communication systems, mainly used to connect optical fiber arrays with various optical devices and systems. During the production process, the end of the FA jumper needs to be ground. Currently, in the industry, grinding of FA relies on the self-weight of the grinding disc as the grinding pressure. When the self-weight is less than the grinding pressure, the pressure can be increased by adding weights. However, when the self-weight is greater than the grinding pressure, generally, the grinding speed is reduced or the grinding time is increased to prevent poor grinding. Doing so has the following disadvantages:

[0003] 1. When the self-weight of the grinding disc is greater than the grinding pressure, it is easy to cause defects such as chipping and short dimensions in the product.

[0004] 2. Although reducing the grinding speed and increasing the grinding time can avoid some defects to a certain extent, they cannot completely avoid them, and the grinding efficiency is even lower. Content of the Utility Model

[0021] Please refer to Figures 1-5 , for further description of the embodiments of the present utility model;

[0022] Such as Figures 1-3As shown in the figure, a FA grinding self-weight reduction device includes: a ceramic ring 2, a support disk 9, a support rod 5, and an elastic limit structure. The support rod 5 is inserted through the support disk 9. A grinding disk 1 is fixedly sleeved at the lower end of the support rod 5. A weighing device 4 is provided below the support rod 5 and the grinding disk 1. The weighing device 4 uses an existing electronic scale to measure the weight of the grinding device. The upper end of the support rod 5 is used to install a motor (not shown), and the motor drives the support rod 5 and the grinding disk 1 to rotate. The elastic limit structure is sleeved on the support rod 5, with its upper end above the support disk 9 and its lower end detachably connected to the support disk 9. The support disk 9 is detachably connected to the ceramic ring 2. The setting of the elastic limit structure is beneficial to transferring the weights of the motor, the support rod 5, and the grinding disk 1 to the support disk 9 and the ceramic ring 2, thereby achieving the purpose of reducing the self-weight of the grinding disk 1. In addition, the elastic limit structure has different compression amounts, and by changing the compression amount of the elastic limit structure, the self-weight of the grinding disk 1 can be adjusted. Six empty positions 11 are provided on the outer periphery of the surface of the support disk 9, and six clamping positions 12 corresponding to the six empty positions 11 are provided on the grinding disk 1. On both sides of the bottom of the ceramic ring 2, there are pads 3 for raising the ceramic ring 2.

[0023] As Figure 2 shown, the elastic limit structure specifically includes an adjusting ring two 8, a spring 7, and an adjusting ring one 6 that are distributed in the upper, middle, and lower positions and are all sleeved on the support rod 5. The upper end of the adjusting ring one 6 is detachably connected to the inner wall of the support disk 9, and the distance between the adjusting ring one 6 and the grinding disk 1 is 15 mm. The upper and lower ends of the spring 7 are respectively in contact with the bottom of the adjusting ring two 8 and the top of the support disk 9.

[0024] As Figure 5 shown, at least two anti-rotation pins 10 are installed on the adjusting ring one 6. The support disk 9 is provided with pin holes equal in number to and corresponding one-to-one with the anti-rotation pins 10. The upper ends of the anti-rotation pins 10 are inserted into the corresponding pin holes. The setting of the anti-rotation pins 10 is to prevent the support disk 9 from rotating following the support rod 5.

[0025] Working principle: The adjusting ring II 8, the spring 7 and the support disc 9 are successively put on the support rod 5. There is a pin hole for installing the anti-rotation pin 10 on the adjusting ring I 6. The anti-rotation pin 10 is pressed into the corresponding pin hole of the adjusting ring I 6. Then, the adjusting ring I 6 with the anti-rotation pin 10 pressed in is put on the support rod 5. Then, the grinding disc 1 is sleeved and fixed at the lower end of the support rod 5. Next, the anti-rotation pin 10 on the adjusting ring I 6 is inserted into the corresponding pin hole of the support disc 9. After that, the position of the support disc 9 is adjusted so that the six vacant positions 11 on the support disc 9 respectively correspond to the six clamping positions 12 on the grinding disc 1. At the same time, the adjusting ring I 6 and the support disc 9 are integrally moved to a position 15 mm away from the surface of the grinding disc 1, and the adjusting ring I 6 is locked. At this time, the lower end of the elastic limit structure is already installed. The position of the adjusting ring II 8 is adjusted to adjust the compression amount of the spring 7. The use of the elastic limit structure can transfer the weights of the support rod 5 and the grinding disc 1 to the support disc 9 and the ceramic ring 2, so as to adjust the self-weight of the grinding disc 1 and adjust it to the required self-weight of the grinding disc 1 on the weighing device 4.

[0026] Compared with the prior art, the advantages of this application are as follows:

[0027] This device uses the elastic limit structure to transfer the self-weight of the grinding disc 1 to the support disc 9 and the ceramic ring 2, so as to achieve the purpose of reducing the self-weight of the grinding disc 1; this device uses different compression amounts of the elastic limit structure. According to the principle of different rebound forces, by changing the compression amount of the elastic limit structure, the purpose of adjustable self-weight of the grinding disc 1 can be achieved. Therefore, the three key parameters of pressure, rotation speed and time during grinding of this device can reach a perfect matching state, thus greatly improving the grinding yield and production efficiency of FA products.
