[0039] Example 1

[0040] See also Figure 1-2 , an automatic optical fiber head polishing machine includes a base 1 and limiting rods 2 at the four end corners of the upper end of the base 1, a polishing block is installed on the upper end of the base, and a connecting block 7 is also connected to the upper end of the base 1, one end of the connecting block 7 is installed with a first block 4, and the other end of the connecting block 7 is installed with a second block 6, a polishing roll 12 is provided inside the first block 4, a first shaft 11 is installed inside the polishing roll 12, the polishing roll 12 is wound around the outer surface of the first shaft 11, a second shaft 13 is installed inside the second block 6, one end of the polishing roll 12 passes through the first block 4, is inserted into the interior of the second block 6 and is wound around the outer surface of the second shaft 13;

[0041] A circular shaft 15 is also installed inside the base 1. The upper end of the circular shaft 15 is connected to the lower end of the connecting block 7. The circular shaft 15 is used to drive the connecting block 7 to move eccentrically around the axis of the circular shaft 15.

[0042] A square sleeve 51 is rotatably connected to one side of the first block 4. A first clamping plate 53 and a second clamping plate 54 are installed on one side of the square sleeve 51. The grinding roll 12 is slidably connected between the first clamping plate 53 and the second clamping plate 54. The first clamping plate 53 and the second clamping plate 54 are used to move the grinding roll 12.

[0043] An electric push rod 25 is installed inside the connecting block 7 , and the upper end of the electric push rod 25 is connected to the lower end of the grinding block 14 .

[0044] according to Figure 1 As shown, the clamp is inserted into the upper end of the limit rod 2 so that the clamp is located at the upper end of the grinding roll 12, and then the optical fiber head is inserted into the clamp so that the optical fiber head contacts the grinding roll 12. Figure 2 As shown, the base 1 is energized, so that the circular shaft 15 drives the connecting block 7 to move eccentrically, and the connecting block 7 drives the grinding roll 12 to rub the lower end of the optical fiber head, so as to grind the optical fiber head. After grinding for a period of time, the grinding block 14 is driven to slide downward by the electric push rod 25, so that the grinding block 14 no longer supports the grinding roll 12, and then the second shaft 13 is rotated, and the second shaft 13 is used to pull part of the grinding roll 12 to wrap around the outer surface of the second shaft 13, so as to pull the grinding roll 12 at the lower end of the optical fiber head through the second shaft 13 to adjust the position, and then the grinding block 14 is returned upward by the electric push rod 25, and the grinding block 14 is supported on the lower end of the grinding roll 12, so that other areas of the grinding sheet will also grind the optical fiber head, thereby improving the grinding accuracy and reducing the waste of grinding sheets.

[0045] Example 2

[0046] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-2 , a beating device 8 is installed at both ends of the grinding block 14, and the beating device 8 is used to beat the grinding roll 12;

[0047] The beating device 8 includes a beating plate 81 connected to one end of the grinding block 14, and the beating plate 81 is used to beat the grinding roll 12;

[0048] The square sleeve 51 is internally slidably connected to a sliding post 52 , one side of the sliding post 52 is connected to one side of the second clamping plate 54 , and the sliding post 52 and the square sleeve 51 are connected via a second spring 24 ;

[0049] A collecting cylinder 3 is installed on one side of the connecting block 7 , and the collecting cylinder 3 is used to collect impurities on the upper end of the grinding roll 12 .

[0050] according to Figure 2As shown, since the lubricating liquid is poured into the upper end surface of the grinding roll 12 when the grinding roll 12 grinds the optical fiber head, a mixture of waste liquid and impurities will be generated after the grinding roll 12 grinds the optical fiber head. When the second shaft 13 rotates and pulls the grinding roll 12 to move its position, the mixture will still remain on the upper end of the grinding roll 12, affecting the accuracy of the next grinding. Therefore, after the grinding roll 12 moves its position, the square sleeve 51 is rotated, so that the square sleeve 51 drives the first clamping plate 53 and the second clamping plate 54 to pull one end of the grinding roll 12 to swing toward the other end. Since the grinding block 14 slides downward and the upper end of the grinding roll 12 has a clamp, the grinding roll 12 located at the upper end of the grinding block 14 will only bend downward to form a concave shape, so that the mixture attached to the grinding roll 12 flows to the curved concave part of the grinding roll 12, so as to collect the mixture on the upper end of the grinding roll 12 after grinding. As the mixture increases, the mixture flows out of the grinding roll 12 under the action of gravity, so that when the position of the grinding roll 12 is subsequently adjusted, the cleaned grinding roll 12 can better grind the optical fiber head;

[0051] It should be noted that according to Figure 2 As shown, both ends of the grinding block 14 are rotatably connected to the striking plates 81. When the grinding block 14 slides downward, one end of the grinding block 14 is rotated upward, so that the two grinding blocks 14 rotate in opposite directions and abut against the grinding roll 12, thereby assisting the grinding roll 12 at the upper end of the grinding block 14 to bend downward.

[0052] Furthermore, in order to improve the cleaning effect of the mixture on the upper end surface of the grinding roll 12, the striking plate 81 is repeatedly rotated so that the striking plate 81 repeatedly strikes the grinding roll 12, thereby vibrating the mixture on the upper end surface of the grinding roll 12 to the curved depression through vibration, thereby improving the cleaning effect.

[0053] Example 3

[0054] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-2 One side of the striking plate 81 is slidably connected to a push post 82 , which is used to lift one side of the grinding roll 12 .

[0055] Furthermore, in order to quickly allow the mixture on the grinding roll 12 to flow out, a push pin 82 is slidably connected to one side of the striking plate 81, and the push pin 82 is located on one side of the grinding roll 12. When the striking plate 81 hits the grinding roll 12, the push pin 82 is slid and squeezed to squeeze one side of the grinding roll 12, so that one side of the grinding roll 12 is tilted upward, so that one side of the curved concave part of the grinding roll 12 is tilted, thereby accelerating the outflow of the mixture.

[0056] Example 4

[0057] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-2 A spray port 83 is installed on one side of the first block 4 and the second block 6 , and the spray port 83 is used to spray liquid toward the grinding roll 12 .

[0058] according to Figure 2 As shown, when the striking plate 81 hits the grinding roll 12, the lubricating liquid is sprayed toward the upper end surface of the grinding roll 12 through the spray port 83, thereby using the lubricating liquid to clean the upper end surface of the grinding roll 12, thereby better cleaning the upper end surface of the grinding roll 12, thereby improving the subsequent grinding roll 12 to better grind the optical fiber head;

[0059] When the position adjustment of the grinding roll 12 is completed, water is continuously sprayed onto the grinding roll 12 through the spray port 83, thereby automatically adding lubricating liquid to assist the grinding roll 12 in grinding the optical fiber head;

[0060] It should be noted that the lubricant is pure water;

[0061] A connecting post 55 is installed on one side of the first block 4. One side of the connecting post 55 is connected to one side of the square sleeve 51. A first torque spring 56 is sleeved on the outer surface of the connecting post 55.

[0062] The first block 4 is internally slidably connected to a first block 57 and a second block 61. An inclined plate 58 is mounted on one end of the first block 57. The inclined plate 58 is used to squeeze the square sleeve 51 to swing toward one end.

[0063] A first limiting plate 59 is installed on one side of the first block 57;

[0064] A second limiting plate 62 is installed on one side of the second block 61 .

[0065] It should be noted that a shifting device 5 is installed on one side of the first block 4 and the second block 6 , so the grinding roll 12 on the upper end of the grinding block 14 is clamped and fixed by two first clamping plates 53 and two second clamping plates 54 .

[0066] Example 5

[0067] This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 1-4 A first spring bead 50 is installed at one end of the slide post 52, a first slot is installed on the inner wall of the square sleeve 51, and an extrusion push block 68 is installed inside the connecting block 7. The extrusion push block 68 is used to squeeze the slide post 52 to slide upward. A circular arc protrusion 68 is provided on one side of the first block 4, and the slide post 52 is used to abut against the circular arc protrusion 68;

[0068] A synchronous belt 84 is provided between the connecting block 7 and the grinding block 14. The grinding block 14 is used to squeeze the synchronous belt 84. The lower end of the synchronous belt 84 is connected to the transmission pipe 67. The interior of the first block 4 is slidably connected to the piston column 66. The transmission pipe 67 is used to push the piston column 66 to slide.

[0069] A short shaft 64 is installed inside the first block 4, an extrusion plate 60 is installed at one end of the short shaft 64, and a force-bearing plate 63 is installed at the other end of the short shaft 64. The force-bearing plate 63, the extrusion plate 60 and the short shaft 64 are connected by a second torsion spring 65. One side of the extrusion plate 60 is hinged to one end of the first block 57, and one side of the force-bearing plate 63 is hinged to one side of the second block 61;

[0070] according to Figure 2 and Figure 3 As shown, when the grinding block 14 slides downward, the grinding block 14 will squeeze the synchronous belt 84 downward, so that the gas inside the synchronous belt 84 flows to the piston column 66 through the transmission pipe 67, thereby using the gas to squeeze the piston column 66 to slide, and the piston column 66 squeezes the squeezing plate 60 to slide to one side, and the squeezing plate 60 drives the first block 57 and the inclined plate 58 to slide to one side, and the inclined plate 58 squeezes the upper end of the square sleeve 51 to swing to the left. Since the square sleeve 51 is connected to one side of the first block 4 through the connecting column 55, when the upper end of the square sleeve 51 swings, the square sleeve 51 uses the connecting column 55 as a fulcrum to make the lower end of the square sleeve 51 slide to the right, so that the square sleeve 51 drives the first clamping plate 53 and the second clamping plate 54 to clamp the grinding roll 12 from the left to the right, so that the first clamping plate 53 and the second clamping plate 54 pull the grinding roll 12 inside the first block 4 to slide out of the first block 4, so that the grinding roll 12 at the upper end of the grinding block 14 bends and concave, and then according to Figure 2 As shown, since the first clamping plate 53 and the second clamping plate 54 clamp the grinding roll 12 at this time, the second shaft 13 rotates and pulls the grinding roll 12 to adjust the position, so the first clamping plate 53 and the second clamping plate 54 release the grinding roll 12. Figure 4 When the second spring 24 drives the slide post 52 to return to its original position, the slide post 52 drives the second clamping plate 54 to contact the grinding roll 12, thereby achieving the goal of fixing the two ends of the grinding roll 12 again;

[0071] When the square sleeve 51 rotates, the grinding block 14 is lifted upward, so that the gas at the transmission pipe 67 flows back to the inside of the synchronous belt 84, so that the piston column 66 no longer conflicts with the extrusion plate 60, so that the first torsion spring 56 drives the connecting column 55 to reset, and the second torsion spring 65 drives the extrusion plate 60 and the force plate 63 to reset, so that the second limiting plate 62 and the first limiting plate 59 are again at the two ends of the square sleeve 51, and the square sleeve 51 is limited by the second limiting plate 62 and the extrusion push block 68, so as to reduce the friction of the optical fiber head pulling the grinding roll 12 and the square sleeve 51 to move and affect the grinding when the grinding roll 12 grinds the optical fiber head;

[0072] It should be noted that a toggle device 5 is installed at one end of the first block 4 and the second block 6. Therefore, the grinding roll 12 is fixed by the first clamping plate 53 and the second clamping plate 54 of the two toggle devices 5, so that the lower end of the grinding roll 12 can be in contact with the upper end of the grinding block 14, so that the lower end of the grinding roll 12 can be supported by the grinding block 14, and there will be no tension on the grinding roll 12 at the upper end of the grinding block 14 to affect the grinding.

[0073] Example 6

[0074] This embodiment is an improvement made on the basis of embodiment 5. For details, please refer to Figure 1-5 One side of the grinding block 14 is rotatably connected to a second gear 85, one side of the second gear 85 and one side of the striking plate 81 are connected to a synchronous belt 84, and a vertical bar 90 is also installed inside the connecting block 7, and a plurality of racks 91 are installed at one end of the vertical bar 90, and the racks 91 are meshed with the second gear 85;

[0075] A second spring bead 87 is provided on one side of the push post 82, and a second slot is provided on the inner wall of the push post 82. The push post 82 is connected to the striking plate 81 via a third spring 86.

[0076] A spray pot 89 is installed inside the grinding block 14, and the striking plate 81 is used to squeeze the spray pot 89. One end of the spray pot 89 is connected to the injection port 83. An arc block 88 is also installed inside the connecting block 7.

[0077] A jet port 83 is installed on one side of the striking plate 81 , and one side of the jet port 83 is connected to one side of the grinding block 14 .

[0078] according to Figure 5As shown, when the grinding block 14 slides downward, the grinding block 14 drives the second gear 85 to mesh with the rack 91, so that the second gear 85 rotates, and the second gear 85 drives the synchronous belt 84 to rotate, and the synchronous belt 84 drives the striking plate 81 to rotate, and the striking plate 81 drives the injection port 83 to rotate, so that the injection port 83 accumulates force, and at the same time, one end of the striking plate 81 will hit the grinding roll 12, so that the striking plate 81 vibrates and cleans the upper end surface of the grinding roll 12, and then when the second gear 85 is no longer in contact with the rack 91, the elastic force is released through the injection port 83, so that the striking plate 81 is reset, and then when the other rack 91 releases the second gear 85, the striking plate 81 rotates again to hit the grinding roll 12, and so on and so forth, so that the striking plate 81 repeatedly hits the grinding roll 12;

[0079] When the striking plate 81 is reset, the striking plate 81 drives the push post 82 to resist against the arc block 88, thereby squeezing the push post 82 to reset and slide through the arc block 88, thereby allowing the second spring bead 87 to snap into the second slot again, thereby achieving the goal of first hitting the grinding roll 12 by the striking plate 81 to collect the mixture to the curved concave part of the grinding roll 12, and then squeezing one side of the grinding roll 12 by the push post 82 to discharge the mixture;

[0080] The first spring bead 50 and the second spring bead 87 are prior art. The working principles are not described in detail here. Both of them include a round bead and a support spring. One end of the round bead is connected to the support spring. When the first spring bead 50 and the second spring bead 87 are subjected to force, the round bead will contract.

[0081] It should be noted that the spray bottle 89 is a prior art. By pressing the spray bottle 89, the liquid is discharged. Figure 5 As shown, after the striking plate 81 rotates and resets, the reset striking plate 81 will hit the button of the spray bottle 89, thereby causing the spray bottle 89 to discharge liquid.

[0082] Example 7

[0083] This embodiment is an improvement made on the basis of embodiment 5. For details, please refer to Figure 1-6A transmission plate 17 is installed at one end of the grinding block 14, and a pull column 19 is installed on the transmission plate 17. The upper end of the pull column 19 is sleeved with a long strip 16. The pull column 19 and the long strip 16 are connected by a first spring 20. A one-way tooth 22 is installed at one end of the long strip 16. A first gear 18 is installed on one side of the second shaft 13, and the one-way tooth 22 is engaged with the first gear 18;

[0084] A spring piece 23 is further installed on the inner wall of the second block 6 , and a protrusion 21 is installed on the other end of the long strip 16 . The protrusion 21 is used to squeeze the spring piece 23 to deform.

[0085] according to Figure 6 As shown, when the grinding block 14 slides downward, the grinding block 14 will drive the transmission plate 17 to slide downward, and the transmission plate 17 drives the pull column 19 to slide downward, and the pull column 19 pulls the first spring 20 and the long strip 16 to slide downward, so that the long strip 16 drives the protrusion 21 to contact the elastic piece 23, so as to first clean the grinding roll 12 at the upper end of the grinding block 14, and then when the downward pulling force of the pull column 19 is greater than the elastic force of the elastic piece 23, the elastic piece 23 is squeezed and deformed by the protrusion 21, so that the long strip 16 slides downward, and the one-way tooth 22 is driven to slide downward by the long strip 16, and the one-way tooth 22 is meshed with the first gear 18, and the first gear 18 drives the second shaft 13 to rotate and pull the grinding roll 12 to adjust the position;

[0086] It should be noted that the unidirectional rotation structure of the one-way tooth 22 is the same as the ratchet principle. The one-way tooth 22 includes an extrusion tooth, a block block and a reset spring. When the grinding block 14 is reset, the transmission plate 17 pushes the long strip 16 and the extrusion tooth of the one-way tooth 22 to slide upward, and the extrusion tooth will be squeezed and rotated downward, thereby driving the first gear 18 to rotate.

[0087] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0088] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
