According to the different pressurization methods, fiber optic grinders are generally divided into two categories: one is the center pressurized fiber optic grinder; the other is the four-corner pressurized fiber optic grinder. The center pressurized grinder is a kind of grinding machine that transmits pressure through the center position of the grinding fixture and changes the grinding pressure by adjusting the position of the weight.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1 See also Figure 1-2 An optical fiber ferrule grinding device comprises a base 1 and a clamping plate 2, a transmission shaft 5 is installed inside the base 1, a clamping device 4 is installed on the upper end of the transmission shaft 5, a clamping device 4 is installed inside the clamping plate 2, an optical fiber head 3 is inserted into the clamping device 4, a cleaning device 6 is arranged at the lower end of the clamping plate 2, the cleaning device 6 is located at one side of the lower end of the optical fiber head 3, and the cleaning device 6 is used to clean the outer surface of the optical fiber head 3; The cleaning device 6 comprises a nozzle 61 mounted at the lower end of the optical fiber head 3, and the nozzle 61 is used to spray liquid onto the outer surface of the lower end of the optical fiber head 3; The clamping device 4 includes a clamping column 41 slidably connected to the inside of the clamping plate 2, and the clamping column 41 is used to drive the optical fiber head 3 to move. A magnetic block 42 is also installed on the inner wall of the clamping plate 2, and the lower end surface of the clamping column 41 is used to abut against the magnetic block 42.

[0025] according to Figure 1As shown, the grinding sheet is attached to the upper end of the clamping device 4, and lubricating liquid is sprayed on the grinding sheet. Then, the clamping plate 2 is buckled on the upper end of the clamping device 4, and several optical fiber heads 3 are inserted into the interior of the clamping device 4. The base 1 is started, and the lower end of the optical fiber head 3 is grinded by the grinding sheet through the clamping device 4. After grinding for a period of time, the clamping column 41 is slid upward, and the optical fiber head 3 is lifted upward by the clamping column 41, so that the lower end of the optical fiber head is separated from the upper end of the clamping device 4, so as to avoid the waste liquid on the upper end of the clamping device 4 from rubbing the optical fiber head 3 when cleaning the optical fiber head 3. Then, the clamping plate 2 is clamped on the upper end of the clamping device 4, and the optical fiber head 3 is grinded by the clamping column 41. The nozzle 61 sprays liquid onto the optical fiber head 3, and cleans the optical fiber head 3 with the liquid, so that the waste liquid attached to the optical fiber head 3 is separated from the optical fiber head 3 and falls to the upper end of the clamping device 4. When a large amount of liquid accumulates on the clamping device 4, the centrifugal force generated by the rotation of the clamping device 4 will throw the dirty liquid scattered on the upper end of the clamping device 4 to the collecting tank 10 to complete the collection. In this way, the outer surface of the optical fiber head 3 and the lower end of the optical fiber head 3 are cleaned, and the waste liquid on the optical fiber head 3 and the clamping device 4 are separated, thereby reducing the particles in the waste liquid that affect the grinding effect, thereby improving the grinding effect.

[0026] Example 2 This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-2 The nozzle 61 is internally slidably connected with an adjustment plate 62, and the adjustment plate 62 is provided with a first hole 63 and a second hole 64, and the first hole 63 and the second hole 64 penetrate the adjustment plate 62; The diameter of the first hole 63 is smaller than the diameter of the adjustment plate 62 .

[0027] according to Figure 3 As shown, an adjustment plate 62 is provided at the nozzle 61, and a first hole 63 and the adjustment plate 62 are provided at one end of the adjustment plate 62. The diameter of the first hole 63 is smaller than the diameter of the adjustment plate 62, so the liquid at the nozzle 61 is first allowed to pass through the first hole 63. Since the diameter of the first hole 63 is small, the liquid sprayed from the first hole 63 has a strong impact force, and since there are a plurality of first holes 63, a plurality of first holes 63 will spray a plurality of fine water columns, and the outer surface and the lower end of the optical fiber head 3 are impacted by the plurality of fine water columns, so as to achieve a better cleaning effect; Furthermore, by rotating the clamping column 41, the clamping column 41 drives the optical fiber head 3 to rotate, so that the water column sprayed from the first hole 63 can wash the optical fiber head 3 over a large area, and the water column sprayed on the surface of the optical fiber head 3 will be refracted and splashed to the outer surfaces of the remaining optical fiber heads 3 due to the rotation of the optical fiber head 3. In this way, multiple optical fiber heads 3 refract and splash each other, thereby better improving the cleaning effect, thereby improving the subsequent grinding effect of the optical fiber head 3 on the upper end of the clamping device 4; A collecting tank 10 is also provided at the upper end of the base 1, and the liquid on the upper end of the clamping device 4 is thrown off to the collecting tank 10 by the eccentric rotation of the clamping device 4; After the optical fiber head 3 is cleaned, the liquid on the outer surface of the clamping device 4 will also be centrifugally thrown off to the collecting tank 10. When there is no lubricant on the upper end of the clamping device 4, the grinding effect will be affected. Therefore, it is necessary to spray lubricant on the upper end of the clamping device 4 again. However, the water column sprayed from the first hole 63 has a large impact, causing the water column to refract in all directions. Therefore, the water column sprayed from the first hole 63 cannot accurately fall on the lower end of the optical fiber head 3, so it is necessary to adjust the spray water pressure according to the Figure 3 As shown, after the first hole 63 is sprayed, the adjustment plate 62 is slid upward so that the second hole 64 on the adjustment plate 62 is connected with the nozzle 61. Since the diameter of the second hole 64 is large, the impact force of the liquid sprayed at the second hole 64 is small, so that the liquid sprayed at the second hole 64 will fall smoothly to the outer surface of the optical fiber head 3 and drain through the optical fiber head 3, so that a large amount of liquid on the outer surface of the optical fiber head 3 falls to the lower end of the optical fiber head 3, so that when the lubricant needs to be supplemented, a large amount of lubricant can be located at the lower end of the optical fiber head 3, so as to facilitate grinding; It should be noted that the lubricating fluid is pure water.

[0028] Example 3 This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-3 A cylinder 45 is installed inside the clamping plate 2, a piston column 46 is slidably connected inside the cylinder 45, the piston column 46 and the cylinder 45 are connected by a first spring 47, the outer surface of the clamping column 41 is rotatably connected to a bearing ring 43, and the upper end of the piston column 46 is connected to the lower end of the bearing ring 43; A driving device 7 is also provided inside the base 1, and the driving device 7 is used to drive the piston column 46 to slide upward; The driving device 7 includes a pressure storage chamber 72 disposed inside the base 1, and the pressure storage chamber 72 is used to transmit air to the inside of the cylinder 45; The cleaning device 6 also includes a piston chamber 65 arranged inside the clamping plate 2, and a first piston plate 66 is slidably connected inside the piston chamber 65, and a push column 67 is installed on the upper end of the first piston plate 66, and a round shaft sleeve 69 is sleeved on the upper end of the push column 67, and a connecting plate 70 is installed on the upper end of the round shaft sleeve 69, and the connecting plate 70 is connected to the clamping plate 2 through the third spring 60, and one end of the connecting plate 70 is connected to one end of the adjustment plate 62; A valve 68 is also installed inside the clamping plate 2 , and the valve 68 is located at the upper end of the first piston plate 66 .

[0029] according to Figure 3As shown, by filling the piston chamber 65 with gas to squeeze the first piston plate 66 to slide upward, the first piston plate 66 pushes the push pin 67 and the round sleeve 69 to slide upward. When the first piston plate 66 slides upward, the first piston plate 66 squeezes the liquid at the upper end to the nozzle 61, so that the first hole 63 or the second hole 64 sprays the liquid column to the outer surface of the optical fiber head 3; When the first piston plate 66 drives the push pin 67 to come into contact with the inside of the round sleeve 69, the push pin 67 will push the round sleeve 69 to slide upward, and the round sleeve 69 will drive the connecting plate 70 to slide upward, and the connecting plate 70 will drive the adjustment plate 62 to slide upward, so that the second hole 64 is connected with the nozzle 61, so as to first spray a strong impact water column through the first hole 63 to clean the optical fiber head 3, and then spray a soft water column through the second hole 64 onto the optical fiber head 3, and drain the liquid to the lower end of the optical fiber head 3 through the optical fiber head 3.

[0030] Example 4 This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-3 The base 1 is also provided with an air cavity 71 inside, and a second piston plate 74 is slidably connected inside the air cavity 71. The second piston plate 74 is connected to the base 1 through a return spring 76. A force column 73 is installed at one end of the second piston plate 74, and the clamping device 4 is used to squeeze the force column 73 to slide toward one end; A first one-way valve 75 is provided between the pressure storage chamber 72 and the air chamber 71; A second one-way valve 77 is disposed inside the air cavity 71; A pressure relief valve 78 is provided at the upper end of the pressure accumulator chamber 72; A through hole 79 is provided at the lower end of the piston chamber 65, and the through hole 79 is used to communicate with the pressure relief valve 78; An air pipe 8 is installed on one side of the cylinder 45 . One side of the air pipe 8 is connected to the interior of the cylinder 45 , and the other side of the air pipe 8 is connected to the interior of the piston chamber 65 .

[0031] The clamping device 4 is driven to move eccentrically by the transmission shaft 5, so that the clamping device 4 continuously squeezes the force-bearing column 73 to slide toward one end. When the force-bearing column 73 slides toward one end, the force-bearing column 73 drives the second piston plate 74 to squeeze the air inside the air cavity 71 through the first one-way valve 75 to the pressure storage chamber 72. Subsequently, when the second piston plate 74 is reset, a negative pressure is generated on the left side of the second piston plate 74, thereby utilizing the negative pressure to extract the air at the second one-way valve 77 to the air cavity 71. In this way, when the second piston plate 74 slides to the left again, the second piston plate 74 will squeeze the air on the left side of the second piston plate 74 again through the first one-way valve 75 into the pressure storage chamber 72, and the pressure is continuously accumulated in the pressure storage chamber 72. When the air pressure reaches a certain level, the air pressure at the pressure storage chamber 72 will lift the pressure relief valve 78, so that the high-pressure gas at the pressure storage chamber 72 flows to the lower end of the first piston plate 66 through the through hole 79, so that the air pressure pushes the first piston plate 66 to slide upward; It should be particularly noted that one end of the air pipe 8 is arranged at the lower end of the first piston plate 66. Therefore, when the through hole 79 transmits high-pressure air, the high-pressure air will first flow to the air pipe 8, thereby transmitting the air to the lower end of the piston column 46 through the air pipe 8, so that the air first pushes the piston column 46 upward to lift it up, so that the piston column 46 pushes the bearing ring 43 and the clamping column 41 to drive the optical fiber head 3 to lift up, so that the optical fiber head 3 is separated from the clamping device 4, and then the air pressure at the lower end of the first piston plate 66 pushes the first piston plate 66 to move upward to squeeze the liquid to clean the outer surface of the optical fiber head 3, so that after the clamping device 4 grinds the optical fiber head 3 many times, the accumulated air pressure first drives the clamping column 41 to slide upward, and then drives the first piston plate 66 to squeeze the liquid.

[0032] Example 5 This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 1-3 A first gear 44 is installed on the upper end of the clamping column 41, and a first synchronous belt 48 is rotatably connected inside the clamping plate 2. The first gear 44 is operably engaged with the first synchronous belt 48. A second gear 49 is rotatably connected to one end of the clamping plate 2, and the second gear 49 is engaged with the first synchronous belt 48; A square column 50 is installed at the lower end of the second gear 49 , and a square sleeve column 51 is rotatably connected inside the base 1 . The square sleeve column 51 is connected to the transmission shaft 5 via a second synchronous belt, and the square column 50 is used to be inserted into the inside of the square sleeve column 51 .

[0033] When the splint 2 is located at the upper end of the base 1, the square column 50 at one end of the splint 2 will be inserted into the interior of the square sleeve column 51; according to Figure 2As shown, when the transmission shaft 5 rotates, the transmission shaft 5 drives the second synchronous belt to rotate, the second synchronous belt drives the square sleeve column 51 to rotate, the square sleeve column 51 drives the square column 50 to rotate, the square column 50 drives the second gear 49 to rotate, the second gear 49 drives the first synchronous belt 48 to rotate, when the clamping column 41 drives the optical fiber head 3 to slide upward, the clamping column 41 also drives the first gear 44 to embed into the first synchronous belt 48, so that the first synchronous belt 48 drives the first gear 44 to rotate, the first gear 44 drives the clamping column 41 and the optical fiber head 3 to rotate, so that the optical fiber head 3 is sprayed and cleaned by the first hole 63 and the second hole 64; It should be noted that according to Figure 3 As shown, a bearing ring 43 is installed on the outer surface of the clamping column 41, so when the clamping column 41 rotates, the inner ring of the bearing ring 43 rotates, and the piston column 46 connected to the outer ring of the bearing ring 43 does not rotate, so the piston column 46 can push the clamping column 41 to slide upward; When the clamping column 41 slides downward to reset, the lower end of the clamping column 41 is magnetically adhered by the magnetic block 42 to fix the clamping column 41, thereby preventing the optical fiber head 3 from being squeezed and moved when the clamping device 4 grinds the optical fiber head 3.

[0034] Example 6 This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 1-5 The interior of the clamping column 41 is slidably connected with an adjusting device 9, and the adjusting device 9 is used to adjust the position of the optical fiber head 3. The adjusting device 9 includes a support seat 91 arranged inside the clamping column 41, and the optical fiber head 3 is used to be inserted into the interior of the support seat 91. A telescopic column 92 is installed at one end of the support seat 91, and the support seat 91 and the clamping column 41 are connected through the telescopic column 92. An adjusting groove 96 is arranged on the clamping plate 2, and the adjusting groove 96 passes through the clamping plate 2 and the clamping column 41; The inside of the clamping column 41 is rotatably connected with a round shaft 93, and the outer surface of the round shaft 93 is installed with a plurality of extrusion strips 94. An arc plate 95 is installed at one end of the support seat 91, and the extrusion strip 94 is used to abut against the arc plate 95; A vertical bar 97 is also installed at the lower end of the clamping plate 2, and one end of the vertical bar 97 is rotatably connected to a rotating plate 98. The rotating plate 98 and the vertical bar 97 are connected by a torque spring 99. A stopper 90 is also provided at one end of the vertical bar 97, and the stopper 90 is located at the upper end of the rotating plate 98.

[0035] according to Figure 4 and Figure 5As shown, when the clamping column 41 slides upward, the vertical bar 97 at the lower end of the clamping plate 2 will be inserted into the interior of the clamping column 41, so that the rotating plate 98 at one end of the vertical bar 97 will abut against one of the squeezing bars 94. Since a stopper 90 is provided at the upper end of the rotating plate 98, the rotating plate 98 abuts against the stopper 90, so that the rotating plate 98 squeezes one of the squeezing bars 94 to rotate downward, and then the squeezing bar 94 is used to abut against the arc plate 95, so that the squeezing bar 94 squeezes the arc plate 95 and the support seat 91 to slide toward one end, and the support seat 91 drives the optical fiber head 3 to move, thereby adjusting the position of the optical fiber head 3, so that the optical fiber head 3 is separated from the used area of ​​the clamping device 4, so that the new grinding area can grind the lower end of the optical fiber head 3, thereby improving the grinding effect; One end of the extrusion strip 94 is installed with rubber, so as to increase the friction between the extrusion strip 94 and the arc plate 95, so that the extrusion strip 94 can better support the support seat 91; It should be noted that the sizes of the plurality of extrusion bars 94 are gradually increased, so that the support seat 91 can be gradually squeezed to move to different positions by the extrusion bars 94 of different sizes; It should be noted that according to Figure 5 As shown, when the clamping column 41 and the support seat 91 slide downward, the rotating plate 98 will abut against other extrusion bars 94, and the other extrusion bars 94 will push the 89 to slide downward, so that the rotating plate 98 and the vertical bar 97 are reset; The telescopic column 92 includes a round shaft cylinder, a retractable rod and a support spring.
