Description

Technical Field

[0001] This invention relates to the field of optical fiber polishing machine technology, and in particular to a polishing disc for a multi-purpose optical fiber connector and its method of use. Background Technology

[0002] Most fiber optic polishing discs rely on their own weight and a pressing lever on the polishing machine to achieve relative fixation. While this method is simple and direct, it lacks the flexibility of pressure adjustment. In practice, the pressure between the polishing machine and the fiber optic connector placed on the polishing disc is often a fixed value and cannot be dynamically adjusted according to polishing needs. When more refined or in-depth polishing of the fiber optic connector is required, operators often have to extend the polishing time. However, simply extending the polishing time is not only inefficient but also makes it difficult to ensure the uniformity of polishing. The polishing quality of the fiber end face may be inconsistent; some areas may be over-polished, causing fiber damage, while other areas may be under-polished, affecting the transmission efficiency of optical signals.

[0003] Secondly, regarding the clamps for fiber optic connectors, the clamp designs commonly used in existing polishing discs typically rely on screwdrivers or torque wrenches for tightening or loosening. This method is not only cumbersome and requires additional tools, but also time-consuming, reducing overall work efficiency.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

Rotating the pressure adjustment rod 200 adjusts the pressure applied to the inner plate 1, thereby adjusting the pressure between the fiber optic connector on the inner plate 1 and the polishing machine. This achieves a more thorough polishing of the fiber optic connector by the polishing machine within the same time and ensures the uniformity of polishing. Secondly, by using a rotary wrench 101 to push the fixing block 100 to clamp or loosen the fiber optic connector, the problem of the existing method of clamping or loosening the fiber optic connector by relying on a screwdriver or torque wrench is overcome, making the fiber optic polishing operation more convenient.

[0068] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0069] Example 1:

[0070] Embodiment 1 of the present invention provides a polishing disc for a multi-purpose fiber optic connector, such as... Figure 1 and Figure 2 As shown, the device includes an inner disk 1 and an outer disk 2, with the inner disk 1 placed on the outer disk 2. A pressure regulating assembly 20 is provided on the outer disk 2, the pressure regulating assembly 20 including a pressure regulating rod 200, the bottom end of which 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. The inner disk 1 has multiple grinding areas, each grinding area corresponding to multiple first receiving grooves 110, and each grinding area corresponding to a clamping assembly 10. The clamping assembly 10 includes a fixing block 100 and a rotating wrench 101 disposed opposite to the multiple first receiving grooves 110. The fixing block 100 is elastically connected to the inner disk 1, and the rotating wrench 101 is rotatably connected to the inner disk 1. The rotating wrench 101 is used to push the fixing block 100 to move, thereby pressing the fiber optic connector housed in the first receiving groove 110.

[0071] In practical applications, the grinding disc provided in this embodiment of the invention is applicable to existing four-corner pressure grinding machines on the market. The fixing block 100 is integrally formed with the inner disc 1. During the specific processing, 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 example, in a grinding area, there are 4 first receiving grooves 110. Taking the inner plate 1 as an example with 8 grinding areas, the grinding machine can grind 32 fiber optic connectors at one time, which is convenient for mass production and improves processing efficiency.

[0073] Since the rotary wrench 101 is disposed on the surface of the inner plate 1, in order to prevent the rotary wrench 101 from coming off the upper surface of the inner plate 1, a limiting block 16 is provided above the rotary wrench 101, and the limiting block 16 is fixedly connected to the inner plate 1 by bolts.

[0074] In this embodiment, by setting a pressure regulating component 20 on the outer plate 2, the bottom end of the pressure regulating rod 200 abuts against the center of the inner plate 1, applying uniform and stable pressure to the inner plate 1. Rotating the pressure regulating rod 200 adjusts the pressure applied to the inner plate 1, thereby adjusting the pressure between the fiber optic connector on the inner plate 1 and the polishing machine. This achieves a more thorough polishing of the fiber optic connector within the same time frame, while ensuring uniform polishing. Secondly, by using a rotary wrench 101 to push the fixing block 100 to clamp or loosen the fiber optic connector, the problem of the existing cumbersome operation of clamping or loosening the fiber optic connector using a screwdriver or torque wrench is overcome, making the fiber optic polishing operation more convenient.

[0075] like Figure 3 and Figure 4 As shown, the tail of the fixing block 100 has a force-receiving part 1003, and the front end of the fixing block 100 has a plurality of fixing plates 1000. The front end of each fixing plate 1000 has a clamping plane 1001, which is opposite to a corresponding first receiving groove 110. The clamping plane 1001 is used to abut against the optical fiber connector, fixing the optical fiber connector within the first receiving groove 110. Figure 3 Taking the fixing plate 1000 shown as an example, the connection between the fixing plate 1000 and the main body of the fixing block 100 is provided with a certain circular arc so that the connection between the fixing plate 1000 and the fixing block 100 has a certain elastic deformation during the pressing process of the fixing block 100 moving forward, so as to avoid the fixing plate 1000 forming a rigid abutment with the fiber optic connector. During the pressing process between the fixing plate 1000 and the fiber optic connector, the fixing plate 1000 is moved by the thrust of the fiber optic connector, which avoids damage to the fiber optic connector, and at the same time ensures the reliability of the fixing plate 1000 in fixing the fiber optic connector after long-term use.

[0076] In one embodiment, the fixing block 100 can be machined to form fixing pieces 1000. The number of fixing pieces 1000 is the same as the number of the first receiving grooves 110, and the fixing pieces 1000 are all cut relatively thin, giving them a certain degree of elasticity. In the arrangement direction of the plurality of first receiving grooves 110, the connection between each fixing piece 1000 and the main body of the fixing block 100 is offset from the corresponding first receiving groove 110, and the structure between adjacent fixing pieces 1000 is hollowed out (i.e., Figure 3(The blank space shown in the image) Each fixing piece 1000 extends from its connection with the main body of the fixing block 100 along a preset arc towards the corresponding first receiving groove 110 until it reaches the first receiving groove 110. The front end (i.e., the free end) of each fixing piece 1000 forms a clamping plane 1001, the width of which matches the width of the opening of the first receiving groove 110. With this structure, on the one hand, the fiber optic connector can be clamped, and on the other hand, the external force transmission path can be extended, so that the external force is applied to the fiber optic connector slowly, avoiding damage to the fiber optic connector.

[0077] During the machining of the inner disk 1, since the fixing block 100 and the inner disk 1 are integrally formed by casting or cutting, the grinding area where the fixing block 100 is located has the shape of a through groove. The fixing block 100 is fixedly connected to the through groove, as shown in the figure below. Figure 3 and Figure 4 As shown, the inner disk 1 is provided with a first through groove 11, and the fixing block 100 is movably disposed in the first through groove 11; the first receiving groove 110 communicates with the first through groove 11; in order to enable the fixing block 100 to be pushed by the moving block 102 in the first through groove 11 and to maintain a fixed connection with the first through groove 11, spring pieces 1002 are respectively provided on both sides of the force-receiving part 1003. One end of each spring piece 1002 is fixedly connected to the side wall of the first through groove 11, and the other end is connected to the force-receiving part 1003, so that the fixing block 100 is elastically connected to the inner disk 1; the main body shape of the spring piece 1002 is semi-circular. Correspondingly, the side wall of the area in the first through groove 11 used to receive the spring piece 1002 is also semi-circular. In the actual processing of the first through groove 11, a protruding corner (such as...) is provided at the junction of the area of ​​the first through groove 11 used to receive the fixing piece 1000 and the area used to receive the spring piece 1002. Figure 3 (As shown in the dashed box), the outer end of each of the spring pieces 1002 is connected to the corner.

[0078] In one embodiment, the fixing pieces 1000 located on both sides of the fixing block 100 extend along the sidewall of the first through groove 11 from the connection point between the fixing piece 100 and the main body of the fixing block 100 until they reach the corresponding first receiving groove 110. The fixing piece 1000 located in the middle region of the fixing block 100 extends obliquely upward from the connection point between the fixing piece 1000 and the main body of the fixing block 100 to the corresponding first receiving groove 110 (within...). Figure 3 (For example, from a certain perspective).

[0079] like Figure 4 As shown, the inner plate 1 is also provided with a first groove 12 that communicates with 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; as shown Figure 5 As shown, the clamping assembly 10 further includes a movable block 102, and the second through slot 120 is used to accommodate the movable block 102. The movable block 102 is clamped between the fixed block 100 and the rotary wrench 101. The inner plate 1 is also provided with a third through slot 13, which communicates with the second through slot 120 and is used to accommodate the rotary wrench 101. The rotary wrench 101 is used to apply external force to the movable block 102 so that the movable block 102 pushes the fixed block 100. To ensure complete contact between the movable block 102 and the fixed block 100, the rear end of the fixed block 100 is planar.

[0080] In one embodiment, see Figure 4 and Figure 5 As shown, the height of the movable block 102 is equal to the height of the second through groove 120, meaning the movable block 102 can be completely embedded in the second through groove 120. The movable block 102 is fixed by the fixing blocks 100 on both sides and the rotating wrench 101. With this design, if the movable block 102 is subjected to an external impact, it is very easy to detach from the top or bottom of the second through groove 120. Therefore, in the preferred embodiment, such 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 come out from below the second through groove 120. Based on the limiting block 16 provided above the rotary wrench 101, the upper part of the movable block 102 is also limited by the limiting block 16, preventing the movable block 102 from coming out from above the second through groove 120.

[0081] For the rotary wrench 101, to facilitate its operation, please refer to... Figure 4 , Figure 5 and Figure 7 As shown, the rotary wrench 101 includes a handle 1010 and a rotating column 1011. The handle 1010 and the rotating column 1011 are fixedly connected. The rotating column 1011 is inserted into the third through slot 13. A first plane 1012 is provided on the rotating column 1011, as shown in the figure. Figure 8As shown, the movable block 102 is provided with a first notch 1020, the bottom surface of which is a second plane 1021; when the first plane 1012 and the second plane 1021 abut, the fixed block 100 is in a relaxed state against the fiber optic connector; when the arc-shaped surface of the rotating column 1011 (not shown in the figure) abuts against the second plane 1021, the fixed block 100 is in a pressed state against the fiber optic connector. 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, then when the first plane 1012 abuts against the second plane 1021, the handle 1010 is collinear with the diameter of the inner disk 1. If the grinding disk needs to be stored after use, the handle 1010, which is collinear with the diameter of the inner disk 1, needs to be moved back to the side to save storage space and avoid excessive impact and deformation of the exposed part of the handle 1010; based on this, in the preferred embodiment, such as Figure 9 As shown, the vertical plane of the first plane 1012 forms an obtuse angle with the plane containing the handle 1010, so that... Figure 10 Taking the positions shown in the dashed box as an example, when the handle 1010 is turned to the leftmost position, the first plane 1012 abuts against the second plane 1021, and when the handle 1010 is turned to the rightmost position, the arc surface of the rotating column 1011 abuts against the second plane 1021.

[0082] For the pressure regulating assembly 20, besides the pressure regulating rod 200, such as Figure 11 As shown, the pressure regulating assembly 20 further includes a first fixed arm 201 and a second fixed arm 202. One end of the first fixed arm 201 is fixedly connected to the pressure regulating rod 200, and the other end is fixed relative to the outer disk 2. One end of the second fixed arm 202 is fixedly connected to the pressure regulating rod 200, and the other end is rotatably connected to the outer disk 2. The first fixed arm 201, the second fixed arm 202, and the pressure regulating rod 200 can be fixedly connected by bolts. Specifically, the outer disk 2 is provided with a first fixing unit 21 and a second fixing unit 22, which are fixedly connected to the outer disk 2. In one embodiment, the first fixing unit 21 and the second fixing unit 22 can be fixedly connected to the outer disk 2 by bolts.

[0083] like Figure 12 As shown, the first fixing unit 21 includes a fixing base 210 and a clamping block 211. The fixing base 210 is fixedly connected to the outer disk 2. The clamping block 211 includes a rotating part 2110, which is rotatably connected to the fixing base 210. Specifically, a fixing shaft 2101 is provided on the fixing base 210, and the rotating part 2110 is rotatably connected to the fixing shaft 2101. A second groove 2100 is provided on the fixing base 210, such as... Figure 13 As shown, the lower end of the first fixed arm 201 is provided with a horizontal section 2010, which is placed in the second groove 2100; the pressing block 211 also includes a limiting part 2111, which is integrally formed with the rotating part 2110. The rotating part 2110 is used to drive the limiting part 2111 to rotate so that the limiting part 2111 covers the upper part of the second groove 2100, thereby limiting the horizontal section 2010; wherein, the limiting part 2111 is provided with a handle for easy manipulation. The fixed base 210 is also provided with a first limiting groove 2102, which is disposed on the upwardly extending side wall of the second groove 2100. The side wall of the limiting part 2111 is provided with a second limiting groove 2112, and the portion of the lower side wall of the second limiting groove 2112 to the bottom end of the limiting part 2111 is located within the first limiting groove 2102. Since the clamping block 211 needs to rotate around the fixed shaft 2101, there is a certain distance between the side wall of the portion of the limiting part 2111 accommodated in the first limiting groove 2102 and the bottom of the first limiting groove 2102, thereby allowing the limiting part 2111 to rotate smoothly. Figure 12 As shown, the second fixing unit 22 is provided with a placement groove 220, and a pin 221 is provided in the placement groove 220. The lower end of the second fixing arm 202 is rotatably connected to the pin 221. In practical applications, by moving the clamping block 211 so that its limiting part 2111 is disengaged from the top of the horizontal section 2010, the pressure adjusting assembly 20 can be rotated upward around the pin 221 as the center and lifted. By rotating the pressure adjusting assembly 20 downward around the pin 221 as the center, the horizontal section 2010 falls into the second groove 2100. Moving the clamping block 211 so that the limiting part 2111 covers the top of the horizontal section 2010, the first fixing arm 201 can be limited. Based on this, the inner plate 1 can be replaced without removing the entire pressure adjusting assembly 20, making the operation simple and convenient.

[0084] Currently, among fiber optic connector products, there is a type of fiber optic connector with the same body but different ferrule lengths (connector A has a ferrule length of 3.95mm, connector B has a ferrule length of 6.5mm). Grinding requires two grinding discs of different heights. However, using multiple grinding discs is inconvenient not only for replacement but also for unnecessary production costs. Therefore, in this embodiment of the invention, as... Figure 14 and Figure 15As shown, the inner disk 1 has multiple first mounting slots 14 and multiple second mounting slots 15 along its edge. The bottom of each first mounting slot 14 has a first step 140, and the bottom of each second mounting slot 15 has a second step 150. The distance between the first step 140 and the bottom surface of the inner disk 1 is less than the distance between the second step 150 and the bottom surface of the inner disk 1. Each first mounting slot 14 has a semi-circular groove 141, which visually distinguishes the first mounting slot 14 from the second mounting slot 15. When the inner disk 1 is placed on the outer disk 2, it is not necessary to carefully observe the markings of the first and second mounting slots 14 and 15 on the inner disk 1; the semi-circular groove 141 is sufficient for differentiation. The first mounting slot 14 is adapted to the grinding disc corresponding to connector A; the second mounting slot 15 is adapted to the grinding disc corresponding to the connector.

[0085] like Figure 16 As shown, the inner side of the outer disk 2 is provided with multiple mounting positions 23, and each mounting position 23 abuts against one of the first step 140 and the second step 150. The different heights of the first step 140 and the second step 150 enable the polishing of two types of fiber optic connectors. When polishing connector A, the first mounting slot 14 on the inner disk 1 is aligned with the mounting position 23 on the outer disk 2, at which point the heights of the inner disk 1 and the outer disk 2 are the same. When polishing connector B, the second mounting slot 15 on the inner disk 1 is aligned with the mounting position 23 on the outer disk 2, at which point the height of the inner disk 1 is lower than the height of the outer disk 2. In practical applications, mounting slots of varying heights can also be provided on the inner disk 1 to accommodate more types of fiber optic connectors, thereby achieving cost savings.

[0086] For the pressure adjusting lever 200, in order to adjust the pressure via the pressure adjusting lever 200, such as Figure 17 As shown, the pressure adjusting rod 200 includes a pressure rod 2000, a transition block 2001, and an adjusting cap 2002 that abut against the center of the inner disk 1. The pressure rod 2000 and the transition block 2001 are slidably connected, and the transition block 2001 and the adjusting cap 2002 are threadedly connected. A circular groove 2003 is provided at the center of the transition block 2001, and a guide slider 2006 is provided at the top of the pressure rod 2000. An abutment block 2007 is provided at the center of the adjusting cap 2002. A spring 2008 is provided in the circular groove 2003. The bottom end of the spring 2008 abuts against the top of the guide slider 2006, and the top end of the spring 2008 abuts against the abutment block 2007. To clearly define the pressure applied to the inner disk 1 each time the adjusting cap 2002 is rotated downwards, as follows... Figure 18 As shown, the adapter block 2001 is provided with a pressure scale line 2009, which is used to display the pressure applied to the inner disk 1.

[0087] The adapter block 2001 and the adjusting cap 2002 are threadedly connected. Specifically, the adapter block 2001 includes an annular post 2011, a circular groove 2003 is located at the center of the annular post 2011, a pressure scale line 2009 is located on the annular post 2011, the inner wall of the circular groove 2003 is provided with a first thread (not shown in the figure), and the side wall of the abutment block 2007 is provided with a second thread (not shown in the figure). The first thread and the second thread are connected, and there is a gap between the abutment block 2007 and the adjusting cap 2002. The gap is used to accommodate the annular post 2011, so that the adjusting cap 2002 appears to be sleeved on the annular post 2011.

[0088] During the continuous application of pressure to the inner disk 1, in order to ensure that the pressure rod 2000 applies pressure evenly to the inner disk 1 and does not cause damage to the surface of the inner disk 1 after long-term use, such as... Figure 19 As shown, a bearing unit 17 is provided at the center of the inner disk 1. The bearing unit 17 is fixedly connected to the inner disk 1. The bottom end of the pressure adjusting rod 200 abuts against the bearing unit 17. The pressure rod 2000 can ensure the stability and uniformity of the applied pressure by applying pressure to the center of the bearing unit 17.

[0089] Based on the above-described solutions provided in the embodiments of the present invention, the embodiments of the present invention also provide a method for using a polishing disc for a multi-purpose fiber optic connector, applicable to the polishing disc for the multi-purpose fiber optic connector described in the above solutions, such as... Figure 20 As shown, it includes:

[0090] In step S1, the fiber optic connector is placed in the first receiving groove 110 of the inner disk 1, and the rotary wrench 101 is turned. The elastic structure between the fixing block 100 and the inner disk 1 is deformed, causing the fixing block 100 to move forward to press the fiber optic connector.

[0091] Specifically, the fixing block 100 is connected to the inner disk 1 via a spring piece 1002. When the rotary wrench 101 is turned, it pushes the fixing block 100 forward. During this movement, the spring piece 1002 deforms. The fixing plate 1000 at the front end of the fixing block 100 presses against the optical fiber connector.

[0092] In step S2, the pressure adjusting rod 200 is rotated to adjust the pressure applied by the pressure adjusting rod 200 to the inner plate 1.

[0093] In step S3, the polishing machine is started to polish the fiber optic connector.

[0094] In step S4, after the fiber optic connector is polished, the rotary wrench 101 is turned, and the elastic structure between the fixing block 100 and the inner disk 1 recovers its deformation, causing the fixing block 100 to move backward, loosening the fiber optic connector, and removing the fiber optic connector.

[0095] After the fiber optic 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 returns to its original shape and drives the fixing block 100 to move backward, so that the fixing piece 1000 loosens the fiber optic connector.

[0096] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
