Description

Technical Field

[0001] The invention relates to the technical field of optical fiber polishers, and in particular to a polishing disc for a multi-purpose optical fiber connector and a use method thereof. Background Art

[0002] Most optical fiber polishing discs rely on their own weight and the pressure rods on the grinder to achieve relative fixation with the grinder. Although this fixing method is simple and direct, it lacks the flexibility of pressure adjustment. In actual operation, the pressure between the grinder and the optical fiber connector placed on the grinding disc is often a fixed value, which cannot be dynamically adjusted according to the grinding requirements. When the optical fiber connector needs to be polished more finely or deeply, the operator can only achieve it by extending the grinding time. However, simply relying on extending the grinding time is not only inefficient, but also difficult to ensure the uniformity of grinding. The grinding quality of the optical fiber end face may be inconsistent. Some areas may be over-polished, causing damage to the optical fiber, while other areas may be under-polished, affecting the transmission efficiency of the optical signal.

[0003] Secondly, regarding the fixture of the optical fiber connector, the fixture design commonly used in existing grinding discs usually relies on a screwdriver or torque wrench to tighten or loosen the fixture.

[0069] Embodiment 1:

[0070] Embodiment 1 of the present invention provides a multi-purpose optical fiber connector polishing disk, such as Figure 1 and Figure 2 As shown, it comprises: an inner disk 1 and an outer disk 2, the inner disk 1 is placed on the outer disk 2; a pressure regulating assembly 20 is arranged on the outer disk 2, the pressure regulating assembly 20 comprises a pressure regulating rod 200, the bottom end of the pressure regulating rod 200 abuts against the center of the inner disk 1; the pressure regulating assembly 20 is used to adjust the pressure between the pressure regulating rod 200 and the inner disk 1; a plurality of grinding areas are arranged on the inner disk 1, each of the grinding areas is correspondingly provided with a plurality of first accommodating grooves 110, and each grinding area is correspondingly provided with a clamp assembly 10, the clamp assembly 10 comprises a fixed block 100 and a rotating wrench 101 which are arranged opposite to the plurality of first accommodating grooves 110, the fixed block 100 is elastically connected to the inner disk 1, the rotating wrench 101 is rotatably connected to the inner disk 1, and the rotating wrench 101 is used to push the fixed block 100 to move so as to compress the optical fiber connector accommodated in the first accommodating groove 110.

[0071] In practical application scenarios, the grinding disc provided by the embodiment of the present invention is applicable to the existing four-corner pressurized grinding machines on the market. The fixing block 100 is integrally formed with the main body of the inner disc 1. In the specific processing process, the fixing block 100 can be formed by cutting the inner disc 1, and the fixing block 100 and the inner disc 1 are connected by an elastic structure.

[0072] by Figure 2 As shown in the figure, in one grinding area, the number of the first receiving grooves 110 is 4. Taking the inner disk 1 as an example, 8 grinding areas are provided, and the grinder can grind 32 optical fiber connectors at one time, which is convenient for batch production and improves processing efficiency.

[0073] Since the rotary wrench 101 is arranged on the surface of the inner disk 1, in order to prevent the rotary wrench 101 from escaping from the upper surface of the inner disk 1, a limit block 16 is arranged above the rotary wrench 101, and the limit block 16 is fixedly connected to the inner disk 1 by bolts.

[0074] In this embodiment, by setting a pressure adjustment component 20 on the outer disk 2, the bottom end of the pressure adjustment rod 200 is abutted against the center of the inner disk 1, and a uniform and stable pressure is applied to the inner disk 1. The pressure adjustment rod 200 is rotated to adjust the pressure applied by the pressure adjustment rod 200 to the inner disk 1, thereby adjusting the pressure between the optical fiber connector on the inner disk 1 and the grinder, so that the grinder can grind the optical fiber connector more fully within the same time and ensure the uniformity of grinding; secondly, by using a rotating wrench 101 to push the fixed block 100 to clamp or loosen the optical fiber connector, the problem of the existing cumbersome operation of clamping or loosening the optical fiber connector by relying on a screwdriver or a torque wrench is overcome, making the optical fiber grinding operation more convenient.

In the process of squeezing the fixing piece 1000 and the optical fiber connector, the fixing piece 1000 is moved by the thrust of the optical fiber connector to avoid damage to the optical fiber connector. At the same time, the reliability of the fixing piece 1000 fixing the optical fiber connector is ensured after the fixing piece 1000 is used for a long time.

[0076] In one embodiment, the fixing block 100 can be cut to form the fixing sheet 1000, the number of the fixing sheets 1000 is the same as the number of the first receiving slots 110, and the fixing sheets 1000 are cut relatively thin, so that the fixing sheets 1000 have a certain elasticity. In the arrangement direction of the plurality of the first receiving slots 110, the connection between each fixing sheet 1000 and the main body of the fixing block 100 is staggered with the corresponding first receiving slot 110, and the structure between adjacent fixing sheets 1000 is hollowed out (that is, Figure 3), each fixing piece 1000 extends from the connection point with the fixing block 100 body to the corresponding first receiving groove 110 according to a preset arc until it reaches the first receiving groove 110, and a clamping plane 1001 is formed at the front end (i.e., the free end) of each fixing piece 1000, and the width of the clamping plane 1001 matches the width of the notch of the first receiving groove 110. According to this structure, on the one hand, the optical fiber connector can be clamped, and on the other hand, the external force transmission path can be extended, so that the external force is slowly applied to the optical fiber connector to avoid damage to the optical fiber connector by the external force.

[0078] In one embodiment, the fixing pieces 1000 located on both sides of the fixing block 100 extend from the connection between the fixing piece 1000 and the main body of the fixing block 100, along the sidewalls of the first through slot 11, until they extend to the corresponding first receiving slot 110. The fixing piece 1000 located in the middle area of ​​the fixing block 100 extends obliquely upward from the connection between the fixing piece 1000 and the main body of the fixing block 100 to the corresponding first receiving slot 110 (with a width of 100 mm). Figure 3 perspective as an example).

[0079] like Figure 4 As shown, the inner plate 1 is further provided with a first groove 12 connected to the first through groove 11, and a portion of the bottom of the first groove 12 is penetrated to form a second through groove 120; Figure 5 As shown, the clamp assembly 10 further includes a moving block 102, the second through slot 120 is used to accommodate the moving block 102, and the moving block 102 is clamped between the fixed block 100 and the rotating wrench 101; the inner plate 1 is further provided with a third through slot 13, the third through slot 13 is communicated with the second through slot 120, and the third through slot 13 is used to accommodate the rotating wrench 101; the rotating wrench 101 is used to apply an external force to the moving block 102, so that the moving block 102 pushes the fixed block 100. In order to make the moving block 102 completely abut against the fixed block 100, the rear end of the fixed block 100 is in a planar shape.

[0080] In one embodiment, see Figure 4 and Figure 5 As shown, the height of the moving block 102 is equal to the height of the second through slot 120, that is, the moving block 102 can be completely embedded in the second through slot 120, and the moving block 102 is squeezed and fixed by the fixing blocks 100 and the rotating wrench 101 on both sides. Under such a design, if the moving block 102 is hit by an external force, it is very easy to fall out from the top or bottom of the second through slot 120. Therefore, in the preferred embodiment, as Figure 6 As shown, the height of the movable block 102 is increased so that its lower half can be embedded in the second through groove 120, and the width of the upper half is widened so that the bottom surface of the widened part can abut against the bottom surface of the first groove 12, thereby ensuring that the movable block 102 will not fall out from the bottom of the second through groove 120. Based on the limit block 16 set above the rotary wrench 101, the top of the movable block 102 is also limited by the limit block 16 to prevent the movable block 102 from falling out from the top of the second through groove 120.

[0081] For the rotary wrench 101, in order to facilitate the operation of the rotary wrench 101, refer to Figure 4 , Figure 5 and Figure 7 As shown, the rotary wrench 101 includes a handle 1010 and a rotary column 1011, the handle 1010 and the rotary column 1011 are fixedly connected, the rotary column 1011 is inserted into the third through slot 13, and a first plane 1012 is provided on the rotary column 1011. Figure 8As shown, the movable block 102 is provided with a first notch 1020, and the bottom surface of the first notch 1020 is a second plane 1021; when the first plane 1012 and the second plane 1021 are in contact, the optical fiber connector of the fixed block 100 is in a relaxed state; when the arc surface (not shown in the figure) of the rotating column 1011 is in contact with the second plane 1021, the optical fiber connector of the fixed block 100 is in a compressed state. In the actual design of the rotary wrench 101, if the first plane 1012 is perpendicular to the plane where the handle 1010 is located, when the first plane 1012 and the second plane 1021 are in contact, the handle 1010 is in line with the diameter of the inner disk 1. If the grinding disk needs to be stored after use, the handle 1010 that is in line with the diameter of the inner disk 1 needs to be moved to the side again to save storage space and prevent the exposed part of the handle 1010 from being deformed by excessive impact; based on this, in the preferred embodiment, Fig. 9 As shown, the vertical plane of the first plane 1012 forms an obtuse angle with the plane where the handle 1010 is located. Fig.10 Taking the position shown in the dotted box as an example, the handle 1010 is turned to the leftmost side so that the first plane 1012 abuts against the second plane 1021 , and the handle 1010 is turned to the rightmost side so that the arc surface of the rotating column 1011 abuts against the second plane 1021 .

Fig.12 As shown, the second fixing unit 22 is provided with a placement groove 220, and a pin shaft 221 is provided in the placement groove 220, and the lower end of the second fixing arm 202 is rotatably connected with the pin shaft 221.

Based on this, the inner disk 1 can be replaced without removing the pressure regulating assembly 20 as a whole, and the operation is simple and convenient.

[0084] Among the current fiber optic connector products, there is a type of fiber optic connector with the same body but different ferrule lengths (connector A ferrule length is 3.95 mm, connector B ferrule length is 6.5 mm). When grinding, two grinding discs with different heights are required. However, using multiple grinding discs is not only inconvenient to replace, but also results in unnecessary production costs. Therefore, in the embodiments of the present invention, Fig.14 and Fig.15As shown, the edge of the inner disk 1 is provided with a plurality of first mounting grooves 14 and a plurality of second mounting grooves 15, the bottom of the first mounting groove 14 is provided with a first step 140, the bottom of the second mounting groove 15 is provided with a second step 150, the distance between the first step 140 and the bottom surface of the inner disk 1 is smaller than the distance between the second step 150 and the bottom surface of the inner disk 1; wherein, a semicircular groove 141 is provided on the first mounting groove 14, and the semicircular groove 141 is used to visually distinguish the first mounting groove 14 and the second mounting groove 15.

Fig.18 As shown, a pressure scale line 2009 is provided on the adapter block 2001 , and the pressure scale line 2009 is used to display the pressure applied to the inner disk 1 .

[0090] In step S1, the optical fiber connector is placed in the first receiving groove 110 of the inner disk 1, and the rotary wrench 101 is turned to deform the elastic structure between the fixing block 100 and the inner disk 1, so that the fixing block 100 is pushed forward to compress the optical fiber connector.

[0091] Specifically, the fixing block 100 is connected to the inner disk 1 through a spring sheet 1002. When the rotating wrench 101 is turned, the rotating wrench 101 pushes the fixing block 100 forward. During the movement of the fixing block 100, the spring sheet 1002 is deformed.

[0094] In step S4, after the optical fiber connector is polished, the rotary wrench 101 is turned, and the elastic structure between the fixed block 100 and the inner disk 1 recovers its deformation, so that the fixed block 100 moves backward, loosens the optical fiber connector, and removes the optical fiber connector.

[0095] After the optical fiber connector is polished, the rotary wrench 101 is turned in the opposite direction to release the external force applied to the fixing block 100, the spring piece 1002 recovers its deformation and drives the fixing block 100 to move backward, so that the fixing piece 1000 releases the optical fiber connector.
