Description

Technical Field

[0001] This utility model relates to the field of pigtail processing technology, specifically a pigtail grinding fixture. Background Technology

[0002] As a key component in optical communication networks for inter-device patching and terminal connections, the quality of the fiber optic pigtail's end face processing directly determines the insertion loss and return loss of the fiber optic connection point, thus affecting the stability and transmission performance of the entire communication system. High-precision, low-roughness grinding and polishing of the exposed fiber end face is a crucial step in the manufacturing process of pigtails.

[0003] In existing technologies, pigtails are clamped using a grinding disc, which provides an independent clamping station for each pigtail. Each grinding disc can only provide a maximum of 60 pigtail clamping stations, resulting in a limited number of pigtails that can be clamped. Furthermore, during clamping, the pigtails need to be manually installed onto the grinding disc one by one, and after grinding, they need to be disassembled one by one, leading to low loading and unloading efficiency and consequently low overall processing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a fiber optic grinding fixture that improves the number of clamps and efficiency, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] A fiber optic grinding fixture includes a first negative pressure seat, a second negative pressure seat, and a cover plate. The second negative pressure seat has two negative pressure chambers inside. The upper surface of the second negative pressure seat has two sets of negative pressure sub-holes, each set communicating with one of the two negative pressure chambers, and each set has ten negative pressure sub-holes. The first negative pressure seat has two channels inside. The bottom of the second negative pressure seat has two through holes communicating with the negative pressure chambers. The bottom of the cover plate has two pressure blocks.

[0007] As can be seen, the two sets of negative pressure holes can hold a total of twenty pigtails. With ten sets per tray, a total of two hundred pigtails can be installed on the grinding tray, increasing the clamping capacity. Furthermore, the twenty pigtails on each set of clamps can be clamped onto the grinding tray at once, improving clamping efficiency.

[0008] Furthermore, sliders are horizontally slidably mounted on both sides of the surface of the second negative pressure seat. A rubber block is provided on the side of the slider facing the negative pressure hole. Measuring screws are installed at both ends of the surface of the second negative pressure seat, with the ends of the measuring screws corresponding to the side of the slider facing away from the rubber block. This eliminates the gap between capillaries and prevents the capillaries from shifting during the grinding process.

[0009] Furthermore, a stop is provided on one side of the upper surface of the first negative pressure seat, and one side of the negative pressure cavity extends to the surface of the second negative pressure seat. This increases the adsorption force point and enhances the fixing effect.

[0010] Furthermore, the surface of the second negative pressure seat is provided with two pads, which are positioned between the two sets of negative pressure holes to protect the sides of the fiber optic cable that need to be ground.

[0011] Furthermore, the upper surface of the cover plate is provided with multiple fastening holes, and two slots are opened on one side of the pressure block. The extrusion pressure at each point of the pressure block can be adjusted independently to ensure that each capillary can receive a relatively uniform extrusion pressure.

[0012] Furthermore, bolt holes are provided on the surface of the cover plate, and corresponding connection holes are provided on the surface of the second negative pressure seat. The cover plate and the second negative pressure seat can be locked together.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] 1. This utility model can hold a total of twenty pigtails through two sets of negative pressure holes, with ten sets per tray, for a total of two hundred pigtails that can be installed on the grinding tray, increasing the clamping capacity. Furthermore, the twenty pigtails on each set of clamps can be clamped onto the grinding tray at once, improving clamping efficiency.

[0015] 2. The first and second negative pressure seats of this utility model are bonded together by negative pressure, eliminating the need for mechanical fastening and resulting in high operating efficiency. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-6 As shown, a fiber optic grinding fixture includes a first negative pressure seat 1, a second negative pressure seat 2, and a cover plate 3. The second negative pressure seat 2 has two negative pressure chambers 201 inside. The upper surface of the second negative pressure seat 2 has two sets of negative pressure sub-holes 202, each set communicating with one of the two negative pressure chambers 201, and each set of sub-holes 202 contains ten holes. The first negative pressure seat 1 has two channels 101 inside. The bottom of the second negative pressure seat 2 has two through holes 206 communicating with the negative pressure chambers 201. The bottom of the cover plate 3 has two pressure blocks 301.

[0020] The vacuum pump is connected to two valve bodies via vacuum tubes, and the two valve bodies are connected to two channels 101 via vacuum tubes respectively. When loading the pigtail, the vacuum pump is started and the valve bodies are opened. The second negative pressure seat 2 is placed on the first negative pressure seat 1, so that the two channels 101 correspond to the two through holes 206 at the bottom of the second negative pressure seat 2. The negative pressure generated by the vacuum pump can act on the negative pressure sub-holes 202 through the channels 101 and the negative pressure chamber 201, and the second negative pressure seat 2 is fixed on the first negative pressure seat 1 under the action of the negative pressure. The pigtail is manually placed into the second negative pressure seat 2, so that the square capillary is aligned above the negative pressure sub-holes 202 until it completely covers all the negative pressure sub-holes 202. The capillary is positioned under the action of the negative pressure. The cover plate 3 is placed on top of the capillary and fixed on the surface of the second negative pressure seat 2. The capillary is pressed from above using the pressure block 301. Finally, turn off the vacuum pump or valve body, remove the second negative pressure seat 2 from the first negative pressure seat 1, and install it on the grinding disc clamping mechanism for grinding.

[0021] After grinding is complete, remove the second negative pressure seat 2 from the clamping mechanism on the grinding disc, put the second negative pressure seat 2 back onto the first negative pressure seat 1, keep the vacuum pump running and keep the valve body open, then remove the cover plate 3, and all twenty pigtails can be removed at once.

[0022] Since a total of twenty pigtails can be placed through the two sets of negative pressure holes 202, with ten sets per disc, a total of two hundred pigtails can be installed on the grinding disc, increasing the clamping capacity. Furthermore, the twenty pigtails on the second negative pressure seat 2 can be fixed at once and clamped onto the grinding disc simultaneously, improving clamping efficiency.

[0023] The rubber block 204 has a certain deformation capacity, which helps to protect the capillary while achieving tight clamping. The pressure block 301 is made of plastic, such as POM, which helps to protect the capillary. The second negative pressure seat 2 is made of copper, and its contact surface with the capillary is ground flat, so that the force is even when the capillary is clamped, which helps to protect the capillary.

[0024] Preferably, sliders 203 are horizontally slidably installed on both sides of the surface of the second negative pressure seat 2. A rubber block 204 is provided on the side of the slider 203 facing the negative pressure hole 202. Organic screws 205 are installed on both ends of the surface of the second negative pressure seat 2. The end of the organic screw 205 corresponds to the side of the slider 203 facing away from the rubber block 204.

[0025] The adjusting screw 205 pushes the slider 203 to slide, so that the rubber block 204 is tightly attached to the capillary from the side. Under the clamping action, the gap between the capillaries is eliminated, preventing the capillary from shifting during the grinding process.

[0026] Preferably, a stop 102 is provided on one side of the upper surface of the first negative pressure seat 1, and one side of the negative pressure cavity 201 extends to the surface of the second negative pressure seat 2.

[0027] When the second negative pressure seat 2 is placed on the surface of the first negative pressure seat 1, one side of the opening of the negative pressure cavity 201 is attached to the surface of the channel 101. Under the action of negative pressure, the bottom and side of the second negative pressure seat 2 are attracted to the first negative pressure seat 1, which increases the attraction force point. At the same time, the side can be used to achieve auxiliary positioning and increase the fixation reliability.

[0028] Preferably, the surface of the second negative pressure seat 2 is provided with two pads 207, and the two pads 207 are disposed between the two sets of negative pressure holes 202.

[0029] The pad 207 is a discarded pigtail and does not participate in the grinding. It is used to protect the side of the pigtail that needs to be ground and prevent the side from being damaged by the copper second negative pressure seat 2.

[0030] Preferably, the upper surface of the cover plate 3 is provided with a plurality of fastening holes 302, and two slots 3011 are provided on one side of the pressure block 301.

[0031] Fastening screws are installed in the fastening hole 302. The pressure of the pressure block 301 on the capillary can be adjusted by turning the fastening screws. Furthermore, the slot 3011 allows for independent adjustment of the pressure at various points of the pressure block 301 by multiple fastening screws, ensuring that each capillary can receive a relatively uniform pressure.

[0032] Preferably, the surface of the cover plate 3 is provided with bolt holes 303, and the corresponding part of the surface of the second negative pressure seat 2 is provided with connecting holes 208.

[0033] The cover plate 3 and the second negative pressure seat 2 can be locked together by fixing screws to ensure stability during the grinding process and prevent the capillary from loosening and shifting.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
