Description

Technical Field

[0001] This invention relates to the field of fiber optic sensitive ring processing technology, specifically a grinding and polishing device and method for using a fiber optic sensitive ring coupled to a Y-waveguide. Background Technology

[0002] The fiber optic sensing ring module consists of a polarization-maintaining fiber optic ring and a Y-waveguide. It is the key optical path for sensing angular rate in fiber optic gyroscopes. In the research and application of fiber optic gyroscopes, the grinding and polishing of the end face of the polarization-maintaining fiber optic sensing ring is a prerequisite for realizing the direct coupling between the polarization-maintaining fiber optic sensing ring and the Y-waveguide chip.

[0003] Currently, in the technology of polishing the end face of the fiber optic sensing ring coupled with the Y-waveguide, polishing machines are mostly used for direct polishing. In order to achieve the smoothness of the end face during polishing, it is necessary to process it multiple times using polishing surfaces of different coarses. This requires changing the polishing surface of the polishing machine. Moreover, the stability of the polishing machine is poor and the polishing accuracy is not high. At the same time, due to the inherent toughness of the fiber optic sensing ring, it will bend when rubbing against the polishing disc, resulting in the tilting of the end face after polishing, which affects the actual production and use. Summary of the Invention

[0004] The purpose of this invention is to provide a fiber optic sensitive ring polishing device and its usage method coupled to a Y-waveguide, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A fiber optic sensitive ring polishing device coupled to a Y-waveguide includes a base, a fixed rod coaxially arranged on the base, a polishing disc rotatably mounted on the fixed rod, and a placement plate fixedly arranged at the end of the fixed rod away from the base.

[0007] A switching mechanism is provided on the shelf, including a moving component and an elastic telescopic component. The moving component includes a moving part that is slidably disposed on the shelf. When the grinding disc rotates, a first pulley fixedly installed on the grinding disc can force the moving part to slide relative to the shelf. During the sliding process of the moving part, the elastic telescopic component can be pulled to cooperate with the fixed part disposed on the fixed rod to fix the position of the sliding moving part.

[0008] A grinding assembly is disposed on the placement plate and includes a mounting cylinder connected to the elastic telescopic assembly. The mounting cylinder is connected to the grinding disc through a linkage structure. When the grinding disc rotates, the mounting cylinder can rotate relative to the elastic telescopic assembly.

[0009] As a further aspect of the present invention: the movable component includes a movable plate slidably disposed on the placement plate, and at least two sets of abutment blocks are equidistantly disposed on the side of the movable plate facing the grinding disc.

[0010] As a further embodiment of the present invention: the elastic telescopic component includes a fixed sleeve fixedly connected to the movable plate, a spring slidably disposed inside the fixed sleeve, one end of the spring abutting against the bottom of the fixed sleeve, and the other end abutting against a telescopic rod slidably disposed inside the fixed sleeve, and a second pulley rotatably mounted on the end of the telescopic rod away from the spring.

[0011] As a further embodiment of the present invention: the fixing member includes two sets of fixing plates symmetrically arranged along the width direction of the shelf, the two sets of fixing plates are fixedly connected to the fixing rod through a connecting plate, and both sets of fixing plates are provided with fitting grooves.

[0012] As a further embodiment of the present invention: the linkage structure includes a rotating shaft rotatably mounted on the shelf, a second connecting plate rotatably mounted on the rotating shaft, a transmission rod rotatably mounted on the end of the second connecting plate away from the rotating shaft, the transmission rod being connected to the rotating shaft and a rotating rod rotatably mounted on the shelf via a second belt and a first belt, and a first connecting plate being rotatably mounted between the transmission rod and the rotating rod.

[0013] As a further embodiment of the present invention: a slide rod is coaxially fixed at one end of the rotating shaft facing the grinding disc, and a lifting cylinder is slidably mounted on the slide rod, the lifting cylinder being connected to the mounting cylinder via a transmission belt.

[0014] As a further embodiment of the present invention: a driven wheel is coaxially fixedly provided at one end of the rotating rod facing the grinding disc, and the driven wheel meshes with the driving wheel coaxially fixedly provided on the grinding disc.

[0015] As a further aspect of the present invention, a method for using a fiber optic sensitive ring polishing and grinding device coupled to a Y-waveguide is also proposed. This method employs the aforementioned fiber optic sensitive ring polishing and grinding device coupled to a Y-waveguide, and includes the following steps:

[0016] Step 1: In the initial state, the mounting cylinder is close to the fixing rod, and the fiber optic sensitive ring coupled to the Y waveguide is fixedly installed on the mounting cylinder, so that the polishing end face of the fiber optic sensitive ring coupled to the Y waveguide contacts the polishing disc. Then the polishing disc is started, and the mounting cylinder will rotate under the action of the linkage structure to polish the fiber optic sensitive ring coupled to the Y waveguide.

[0017] Step 2: Rotating the grinding disc once drives the first pulley to engage with the abutment block mounted on the moving plate, forcing the moving plate to gradually move away from the fixed rod. At this time, the second pulley slides along the fitting groove, driving the mounting cylinder to rise along the axial direction of the fixed rod, so that the end face of the fiber sensing ring of the coupled Y waveguide separates from the grinding disc.

[0018] Step 3: After the first pulley separates from the abutment block, the spring releases its elastic potential energy, pushing the second pulley to continue sliding along the interlocking groove. After the second pulley stops moving, the end face of the fiber sensitive ring coupled to the Y waveguide re-contacts the polishing disc for further polishing.

[0019] Step 4: Repeat steps 2 and 3 above to complete the polishing of the fiber sensing ring coupled to the Y-waveguide.

[0020] Step 5: After polishing, turn off the polishing disc, remove the fiber optic sensitive ring coupled to the Y-waveguide, and then push the moving plate toward the fixed rod. After returning to the initial position, the next set of fiber optic sensitive rings coupled to the Y-waveguide can be polished.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] By setting up a switching mechanism and a polishing component, the cooperation between the two can drive the mounting cylinder of the fixed coupled Y-waveguide fiber sensitive ring to rotate when the polishing disc rotates. This not only speeds up the polishing speed of the polishing disc on the end face of the coupled Y-waveguide fiber sensitive ring, but also makes the polished end face of the coupled Y-waveguide fiber sensitive ring tend to be flat during the polishing process.

[0023] Meanwhile, during the rotation of the grinding disc, the cooperation between the first pulley and the abutment block, as well as the cooperation between the elastic telescopic component and the fitting groove, enables the fiber optic sensitive ring of the coupled Y-waveguide fixed in the mounting cylinder to be quickly switched on the grinding surfaces of different precision on the grinding disc, so as to quickly realize the grinding and polishing work of the end face of the fiber optic sensitive ring of the coupled Y-waveguide, shorten the processing time, and increase the processing speed.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0035] Please see Figures 1-8 In this embodiment of the invention, a fiber optic sensitive ring polishing device coupled to a Y-waveguide includes a base 1, a fixing rod 5 coaxially arranged on the base 1, a polishing disc 6 rotatably mounted on the fixing rod 5, and a placement plate 10 fixedly arranged at the end of the fixing rod 5 away from the base 1.

[0036] To elaborate, please refer to Figure 1 The aforementioned fixed rod 5 is provided with an installation plate 2. The installation plate 2 is fixedly installed on the side facing the base 1. The output shaft of the motor 3 passes through the installation plate 2 and is connected to the fixed rod 5 through the linkage belt 4. When the motor 3 is started, under the action of the linkage belt 4, it can drive the grinding disc 6 to rotate continuously in the same direction.

[0037] Preferably, please refer to Figure 1 , Figure 2 The aforementioned polishing disc 6 consists of three sets of polishing surfaces with different precisions. From the axis outwards, they are distributed as a coarse polishing disc 603, a medium polishing disc 602, and a fine polishing disc 601. Through polishing with discs of different precisions, the end face of the fiber optic sensitive ring coupled to the Y-waveguide can be polished. The height of the three sets of polishing surfaces increases sequentially from the inside out to compensate for the wear of the end face of the fiber optic sensitive ring coupled to the Y-waveguide. This ensures that when the fiber optic sensitive ring is transferred to the polishing discs of different precisions, the end face of the fiber optic sensitive ring coupled to the Y-waveguide is always in contact with the polishing disc, thus performing the polishing work.

[0038] The switching mechanism is set on the shelf 10 and includes a moving component and an elastic telescopic component. The moving component includes a moving part that is slidably set on the shelf 10. When the grinding disc 6 rotates, the first pulley 13 fixedly installed on the grinding disc 6 can force the moving part to slide relative to the shelf 10. During the sliding process of the moving part, it can pull the elastic telescopic component to cooperate with the fixing part set on the fixing rod 5 to fix the position of the sliding moving part.

[0039] The movable component includes a movable plate 11 that is slidably disposed on the placement plate 10, and at least two sets of abutment blocks 1102 are equidistantly disposed on the side of the movable plate 11 facing the grinding disc 6.

[0040] For details, please refer to Figure 3 , Figure 4Corresponding to the above three sets of grinding surfaces, the above-mentioned abutment block 1102 is provided in two sets. The two sets of abutment blocks 1102 are inclined blocks arranged parallel to each other. The above-mentioned moving plate 11 is symmetrically provided with two sets of locking grooves 1101 along its width direction on the side facing the placement plate 10. The above-mentioned placement plate 10 is symmetrically provided with two sets of locking blocks 1002 along its width direction. The locking blocks 1002 are slidably disposed in the locking grooves 1101. When the grinding disc 6 is driven by the motor 3 to rotate one revolution in the same direction, the first pulley 13 will generate basic compression with the abutment block 1102, thereby pushing the moving plate 11 to slide along the locking grooves 1101, thereby driving the elastic telescopic component away from the fixed part, so that the fiber optic sensitive ring coupled to the Y waveguide on the moving plate 11 can move to the next precision grinding surface.

[0041] The elastic telescopic assembly includes a fixed sleeve 14 fixedly connected to the movable plate 11. A spring 15 is slidably disposed inside the fixed sleeve 14. One end of the spring 15 abuts against the bottom of the fixed sleeve 14, and the other end abuts against a telescopic rod 16 slidably disposed inside the fixed sleeve 14. A second pulley 17 is rotatably mounted on the end of the telescopic rod 16 away from the spring 15.

[0042] The fastener includes two sets of fixing plates 12 symmetrically arranged along the width direction of the shelf 10. The two sets of fixing plates 12 are fixedly connected to the fixing rod 5 through a connecting plate, and each set of fixing plates 12 is provided with a fitting groove 1201.

[0043] For details, please refer to Figure 2 , Figure 5 , Figure 8 The aforementioned fitting groove 1201 has a continuous wavy structure, including two sets of crests and three sets of troughs. The three sets of troughs correspond to the grinding positions of different grinding surfaces. For a more detailed explanation, please refer to [link to relevant documentation]. Figure 3 , Figure 4 , Figure 5Initially, the spring 15 is compressed, pushing the telescopic rod 16 away from the moving plate 11 so that the second pulley 17 is positioned at the first end of the fitting groove 1201 and engages with the first set of troughs near the fixed rod 5. At this time, the telescopic rod 16 is directly above the grinding surface of the coarse grinding disc 603. As the first pulley 13 rotates one revolution with the grinding disc 6, the first pulley 13 will contact and press against the abutment block 1102 on the moving plate 11 away from the fixed rod 5, thereby forcing the moving plate 11 to drive the fixed sleeve. As the fixed sleeve 14 and telescopic rod 16 gradually move away from the fixed rod 5, the second pulley 17 slides along the fitting groove 1201, gradually approaching the first set of crests in the fitting groove 1201, causing the spring 15 to be further compressed. This continues until the first pulley 13 separates from the abutment block 1102, at which point the second pulley 17 just passes the crest. At this point, the spring 15 releases some elastic potential energy, pushing the second pulley 17 along the side wall of the fitting groove 1201 to the second set of troughs. At this time, the telescopic rod 16 is located on the middle grinding disc. Directly above the 602 grinding surface; as the grinding disc 6 continues to rotate, after one cycle, the first pulley 13 will again come into contact with and press against the abutment block 1102 near the fixed rod 5, thereby pushing the moving plate 11 further away from the fixed rod 5. During this process, the second pulley 17 slides along the groove wall of the fitting groove 1201, gradually moving to the second peak, further compressing the spring 15, until the first pulley 13 separates from the abutment block 1102 again, and the second pulley 17 just passes the second peak. Then the spring 15 releases its elastic potential energy, pushing the second pulley. 17. Move along the groove wall of the fitting groove 1201 to the third trough. At this time, the telescopic rod 16 is located directly above the grinding surface of the fine grinding disc 601, which can complete the secondary grinding and polishing of the end face of the fiber sensitive ring coupled to the Y waveguide. In particular, the grinding surface of the grinding disc 6 can be increased or reduced according to the actual situation. Correspondingly, the number of abutment blocks 1102 is one less than the number of grinding surfaces, while the number of troughs is the same as the number of grinding surfaces, and the number of peaks is the same as the number of abutment blocks 1102. This allows for a higher precision grinding and polishing operation on the fiber sensitive ring coupled to the Y waveguide.

[0044] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 A fiber optic sensitive ring polishing device coupled to a Y-waveguide further includes a polishing assembly disposed on the placement plate 10, including a mounting cylinder 24 connected to the elastic telescopic assembly. The mounting cylinder 24 is connected to the polishing disc 6 through a linkage structure. When the polishing disc 6 rotates, the mounting cylinder 24 can rotate relative to the elastic telescopic assembly.

[0045] For details, please refer to Figure 1 , Figure 5 The aforementioned mounting cylinder 24 is used to clamp and fix the fiber optic sensitive ring of the coupled Y-waveguide, and is rotatably connected to the sleeve ring 18 fixed on the telescopic rod 16. The end of the mounting cylinder 24 is close to the grinding disc 6. After the fiber optic sensitive ring of the coupled Y-waveguide to be ground is installed in the mounting cylinder 24, only a small section of the fiber optic sensitive ring of the coupled Y-waveguide to be processed is exposed in the mounting cylinder 24 and in contact with the grinding disc 6. This is to prevent the fiber optic sensitive ring of the coupled Y-waveguide from being deflected due to friction when the grinding disc 6 performs the grinding work, so that the grinding surface of the fiber optic sensitive ring of the coupled Y-waveguide is smooth and flat for subsequent use.

[0046] The linkage structure includes a rotating shaft 19 rotatably mounted on the shelf 10, a second connecting plate 20 rotatably mounted on the rotating shaft 19, a transmission rod 27 rotatably mounted on the end of the second connecting plate 20 away from the rotating shaft 19, the transmission rod 27 being connected to the rotating shaft 19 and the rotating rod 7 rotatably mounted on the shelf 10 via a second belt 21 and a first belt 23, and a first connecting plate 22 being rotatably mounted between the transmission rod 27 and the rotating rod 7;

[0047] A slide rod 1901 is coaxially fixed at one end of the rotating shaft 19 facing the grinding disc 6. A lifting cylinder 26 is slidably mounted on the slide rod 1901. The lifting cylinder 26 is connected to the mounting cylinder 24 through a transmission belt 28.

[0048] For details, please refer to Figure 5 , Figure 7 The aforementioned rotating shaft 19 is slidably disposed in the through slot 1001 opened on the shelf plate 10. The end of the sliding rod 1901 away from the rotating shaft 19 is rotatably mounted on the connecting plate connected to the sleeve ring 18 and the telescopic rod 16, so that when the telescopic rod 16 slides along the length direction of the shelf plate 10, the rotating shaft 19 will slide synchronously with the telescopic rod 16. Subsequently, under the connection action of the first connecting plate 22 and the second connecting plate 20, the rotating rod 7 can continuously drive the rotating shaft 19 to rotate, thereby driving the mounting cylinder 24 to rotate, so that the fiber optic sensitive ring coupled to the Y waveguide will rotate.

[0049] For details, please refer to Figure 7A pulley 25 is coaxially fixed at one end of the mounting cylinder 24 facing the moving plate 11. The radius of the pulley 25 is several times the radius of the lifting cylinder 26. In particular, two sets of protrusions 2601 are equidistantly arranged on the inner wall of the lifting cylinder 26 along its circumference. The protrusions 2601 are slidably arranged in the grooves 1902 provided by the slide rod 1901, so that the lifting cylinder 26 can only move up and down along the axial direction of the rotating shaft 19. When the rotating shaft 19 rotates, the lifting cylinder 26 will rotate synchronously with the rotating shaft 19. Under the connection of the transmission belt 28, the lifting cylinder 26 will drive the mounting cylinder 24 to rotate, so that the fiber optic sensitive ring coupled to the Y waveguide installed in the mounting cylinder 24 will rotate, thereby accelerating the polishing speed and shortening the processing time.

[0050] A driven wheel 8 is coaxially fixed at one end of the rotating rod 7 facing the grinding disc 6, and the driven wheel 8 meshes with the driving wheel 9 coaxially fixed at the grinding disc 6;

[0051] To elaborate, please refer to Figure 1 , Figure 5 The aforementioned drive wheel 9 is coaxially fixed with the grinding disc 6 and rotatably connected to the fixed rod 5. When the motor 3 starts, the continuously rotating output shaft of the motor 3 will drive the grinding disc 6 and the drive wheel 9 to rotate continuously in the same direction. At this time, the drive wheel 9 and the driven wheel 8 enter a meshing transmission state, which can drive the driven wheel 8 and the drive wheel 9 to rotate continuously in opposite directions. When the driven wheel 8 rotates, the rotating rod 7 will drive the transmission rod 27 to rotate under the connection of the first belt 23. Subsequently, the transmission rod 27 will drive the rotating shaft 19 to rotate under the connection of the second belt 21. Shaft 19, in cooperation with the sliding groove 1902 and the protrusion 2601, will drive the lifting cylinder 26 to rotate synchronously with the rotating shaft 19. Due to the proportional relationship between the lifting cylinder 26 and the mounting cylinder 24, the lifting cylinder 26, which rotates continuously with the rotating shaft 19 for multiple revolutions, will drive the mounting cylinder 24 to rotate once. This allows the mounting cylinder 24 to drive the fiber optic sensitive ring coupled to the Y-waveguide to rotate when the grinding disc 6 rotates. This not only speeds up the grinding speed of the grinding disc 6 on the end face of the fiber optic sensitive ring coupled to the Y-waveguide, but also makes the grinding end face of the fiber optic sensitive ring coupled to the Y-waveguide tend to be flat during the grinding process.

[0052] In summary, in the initial state, the mounting cylinder 24 is positioned directly above the grinding surface of the coarse grinding disc 603. When the motor 3 is started, the grinding disc 6 and the mounting cylinder 24 rotate simultaneously, grinding the fiber optic sensitive ring coupled to the Y-waveguide within the mounting cylinder 24. After the grinding disc 6 rotates one revolution, the first pulley 13 engages with the abutment block 1102, forcing the moving plate 11 away from the fixed rod 5. This causes the second pulley 17 to slide within the fitting groove 1201. After the first pulley 13 separates from the abutment block 1102, the second pulley 17, under the action of the spring 15, drives the mounting cylinder 24, which is rotatably mounted on the telescopic rod 16, to move to the upper end of the grinding surface of the intermediate grinding disc 602. During this movement, the fiber optic sensitive ring coupled to the Y-waveguide within the mounting cylinder 24 is ground. The ring will quickly switch to the grinding surface of the intermediate grinding disc 602. At this time, the intermediate grinding disc 602, which is slightly higher than the coarse grinding disc 603, comes into contact with the fiber optic sensitive ring coupled to the Y-waveguide after grinding, and can perform a round of polishing on the grinding end face of the fiber optic sensitive ring coupled to the Y-waveguide. Then the grinding disc 6 continues to rotate one revolution, and the first pulley 13 will cooperate with the next set of abutment blocks 1102, and once again drive the moving plate 11 away from one end of the fixed rod 5. During this process, the second pulley 17 and the telescopic rod 16 will repeat the above process, moving the mounting cylinder 24 to directly above the grinding surface of the fine grinding disc 601, so that the fiber optic sensitive ring coupled to the Y-waveguide placed in the mounting cylinder 24 will quickly switch to the fine grinding disc 601 for secondary polishing, thereby making the end face of the fiber optic sensitive ring coupled to the Y-waveguide smoother and flatter.

[0053] A fiber optic sensitive ring polishing and grinding device coupled to a Y-waveguide is disclosed, along with a method for using the device. The method comprises the following steps:

[0054] Step 1: In the initial state, the mounting cylinder 24 is close to the fixing rod 5, and the fiber optic sensitive ring coupled to the Y waveguide is fixedly installed on the mounting cylinder 24, so that the polishing end face of the fiber optic sensitive ring coupled to the Y waveguide contacts the polishing disc 6. Then the polishing disc 6 is started, and the mounting cylinder 24 will rotate under the action of the linkage structure to polish the fiber optic sensitive ring coupled to the Y waveguide.

[0055] Step 2: The grinding disc 6 rotates one revolution, causing the first pulley 13 to engage with the abutment block 1102 mounted on the moving plate 11, forcing the moving plate 11 to gradually move away from the fixed rod 5. At this time, the second pulley 17 slides along the fitting groove 1201, causing the mounting cylinder 24 to rise along the axial direction of the fixed rod 5, so that the end face of the fiber sensitive ring of the coupled Y waveguide is separated from the grinding disc 6.

[0056] Step 3: After the first pulley 13 separates from the abutment block 1102, the spring 15 releases its elastic potential energy, pushing the second pulley 17 to continue sliding along the fitting groove 1201. After the second pulley 17 stops moving, the end face of the fiber sensitive ring coupled to the Y waveguide re-contacts the polishing disc 6 for further polishing.

[0057] Step 4: Repeat steps 2 and 3 above to complete the polishing of the fiber sensing ring coupled to the Y-waveguide.

[0058] Step 5: After polishing, turn off the polishing disc 6, remove the fiber optic sensitive ring coupled to the Y waveguide, and then push the moving plate 11 toward the fixed rod 5. After returning to the initial position, the next set of fiber optic sensitive rings coupled to the Y waveguide can be polished.

6. A method for using a fiber optic sensitive ring polishing and grinding device coupled to a Y-waveguide, comprising the fiber optic sensitive ring polishing and grinding device coupled to a Y-waveguide as described in claim 3, characterized in that... Includes the following steps: Step 1: In the initial state, the mounting cylinder (24) is close to the fixing rod (5), and the fiber sensing ring of the coupled Y waveguide is fixedly installed on the mounting cylinder (24), so that the polishing end face of the fiber sensing ring of the coupled Y waveguide contacts the polishing disc (6). Then the polishing disc (6) is started, and the mounting cylinder (24) will rotate under the action of the linkage structure to polish the fiber sensing ring of the coupled Y waveguide. Step 2: The grinding disc (6) rotates once, causing the first pulley (13) to engage with the abutment block (1102) mounted on the moving plate (11), forcing the moving plate (11) to gradually move away from the fixed rod (5). At this time, the second pulley (17) slides along the fitting groove (1201), causing the mounting cylinder (24) to rise along the axial direction of the fixed rod (5), so that the end face of the fiber sensitive ring of the coupled Y waveguide is separated from the grinding disc (6). Step 3: After the first pulley (13) separates from the abutment block (1102), the spring (15) releases its elastic potential energy and pushes the second pulley (17) to continue sliding along the fitting groove (1201). After the second pulley (17) stops moving, the end face of the fiber sensitive ring coupled to the Y waveguide contacts the polishing disc (6) again for further polishing. Step 4: Repeat steps 2 and 3 above to complete the polishing of the fiber sensing ring coupled to the Y-waveguide. Step 5: After polishing, turn off the polishing disc (6), take out the fiber optic sensitive ring, and then push the moving plate (11) toward the fixed rod (5). After returning to the initial position, the next set of fiber optic sensitive rings coupled to the Y waveguide can be polished.
