Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber fixtures, in particular to a convenient and efficient optical fiber array quick-install grinding fixture. Background Art

[0002] Fiber Array (FA) is an array formed by installing a bundle of optical fibers or a fiber ribbon on a substrate at a specified interval using a V-groove substrate. During the processing of the fiber array, the end face of the light array needs to be polished, and a fiber array polishing fixture is required during the polishing process. The fiber array is made of transparent quartz and high borosilicate, which increases the difficulty of polishing the 45-degree end face.

[0003] At present, the optical grinding fixture of the optical fiber array mainly fixes the optical fiber array by locking the hexagonal screws. This method will cause cumbersome operation, low production efficiency, and low product qualification rate. Therefore, it is necessary to develop a new type of quick-install grinding fixture for optical fiber array to solve these problems. Utility Model Content

[0005] The technical solution adopted by the utility model is as follows:

[0006] A fiber array quick-loading grinding fixture comprises a base body, on which a plurality of fiber arrays are clamped, and N array-distributed fixing seats are fixedly installed on the base body along the circumferential direction, forming a corresponding match with N array-distributed insertion slots provided on the base body, where N is greater than or equal to 3; a connecting pin is inserted in each fixing seat along the radial direction of the base body, and the end of the connecting pin close to the center of the base body is a head, a spring sleeved on the connecting pin abuts against the fixing seat, and a rotating block is provided on the outer side of the fixing seat, and the outermost end of the connecting pin is pivotally connected to the rotating block through a fixing pin, and the connecting pin moves forward and backward horizontally under the flipping traction of the rotating block, so that the corresponding fiber array is clamped in the insertion slot or released.

[0007] As a further improvement of the above technical solution:

[0008] The base comprises a circular base and an annular outer seat which are cocentrically connected and connected to each other. The outer circumference of the circular base is provided with N array-distributed insertion grooves along the radial direction. The N array-distributed fixing seats are fixedly installed on the annular outer seat along the circumferential direction.

[0009] The rotating block adopts a square structure, with a handle installed on the top of the rotating block. A through transverse groove is opened on the rotating block to accommodate the channel for the movable insertion of the connecting pin. On both sides of the transverse groove are left and right vertical plates, and the fixing pin passes through the left and right vertical plates and the ends of the connecting pins therein to realize pivot connection.

[0010] The left and right vertical plates of the rotating block have abutment surfaces that abut against the fixed seat, and the bottom corners of the abutment surfaces are provided with round chamfers. The handle operates the rotating block to flip 90° with the round chamfers of the bottom corners as the fulcrum; when the rotating block flips from a vertical state to a horizontal state, the connecting pin compresses the spring and retreats horizontally outward under the traction of the rotating block; when the rotating block flips from a horizontal state to a vertical state, the connecting pin moves horizontally inward under the release action of the spring.

[0011] The rotating block has abutting surface against the fixed seat, and the distance from the fixed pin on the connecting pin to the abutting surface on the rotating block is smaller than the distance from the fixed pin on the connecting pin to the bottom surface of the rotating block.

[0013] A mounting groove is provided on the side of the push block facing the center of the base body, and a clamping head is installed in the mounting groove of the push block. Each clamping head faces the circular base and forms a corresponding clamping fit with the insertion groove on the circular base.

[0014] The clamping head is located on the push block near the bottom, and forms pressure on the joint part of the optical fiber array. The matching surface between the clamping head and the optical fiber array is an inclined surface with an inclined angle.

[0015] The screws penetrate the inner opening of the annular outer seat from the bottom of the annular outer seat and are connected to the fixing seat above the annular outer seat, so that the fixing seat can be detachably installed on the annular outer seat.

[0016] A guide groove is formed between the circular base and the annular outer seat, and a push block is sleeved and installed on the rod portion of the connecting pin close to the head. The push block is located in the guide groove and slides linearly forward and backward under the drive of the connecting pin.

[0017] The beneficial effects of the utility model are as follows:

[0018] 1.

[0019] 2. The utility model adopts multiple components to assemble the finished product, which is easy to assemble and there is no difficulty in assembly. Therefore, the assembly production is very fast and the processing difficulty is low. Moreover, it is very convenient to disassemble and assemble, and it is easy to maintain.

[0028] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 5 As shown, the optical fiber array quick-install grinding fixture of the utility model has a base 2, on which a plurality of optical fiber arrays 1 are clamped and fixed, and the base 2 includes a circular base 3 and an annular outer seat 4 arranged concentrically, the annular outer seat 4 surrounds the outer circumference of the circular base 3, and the annular outer seat 4 and the circular base 3 are connected as a whole through connecting rods arranged at intervals. N array-distributed insertion grooves are radially provided on the outer circumference of the circular base 3, and correspondingly, N array-distributed fixing seats 5 are fixedly installed on the annular outer seat 4 along the circumferential direction, and N ≥ 3.

[0030] Each fixed seat 5 is provided with a corresponding connecting pin 6 inserted along the radial direction of the base 2. The end of the connecting pin 6 close to the center of the base 2 is the head, and the rod of the connecting pin 6 passes through the body of the fixed seat 5 toward the outer circumference of the base 2. A rotating block 7 is provided on the outside of the fixed seat 5. The outermost end of the connecting pin 6 away from the center of the base 2 is movably pivoted with the rotating block 7 through a fixed pin 8. The rotating block 7 abuts against and cooperates with the fixed seat 5. The connecting pin 6 can move forward and backward horizontally under the flipping traction of the rotating block 7.

[0031] A push block 11 is sleeved on the rod portion of the connecting pin 6 near the head, and a spring 9 is sleeved on the connecting pin 6 between the push block 11 and the fixing seat 5. The two ends of the spring 9 are respectively against the push block 11 and the fixing seat 5, and the spring 9 is in a compressed state to form a thrust on the push block 11. The upper part of the push block 11 is sleeved on the connecting pin 6, and the main body of the push block 11 is located below the connecting pin 6. The push block 11 is arranged radially toward the base 2, and the push block 11 forms a corresponding match with the insertion groove opened on the circular base 3.

[0032] A mounting groove is provided on the side of the push block 11 facing the center of the circle of the base 2, and a clamping head 12 is installed in the mounting groove of the push block 11. Each clamping head 12 faces the circular base 3 and forms a one-to-one correspondence with the insertion groove on the circular base 3. The clamping head 12 presses the circular base 3 to clamp the joint part of the optical fiber array 1 placed in the insertion groove in the insertion groove position of the circular base 3. Preferably, the clamping head 12 is located near the bottom of the push block 11, and forms a shoveling pressure on the joint part of the optical fiber array 1. In order to form a good match with the joint part of the optical fiber array 1, the matching surface of the clamping head 12 and the optical fiber array 1 is designed to be an inclined surface with an inclined angle. The joint part of the optical fiber array 1 is exposed downward from the bottom of the circular base 3, which is convenient for grinding and processing.

[0033] The rotating block 7 adopts a square structure, and a handle 10 is fixedly installed on the top of the rotating block 7. A through transverse groove is provided on the rotating block 7 to accommodate the passage for the connection pin 6 to move through. The left and right vertical plates are on both sides of the transverse groove. The fixed pin 8 penetrates the left and right vertical plates and the ends of the connection pin 6 therein, so that the connection pin 6 and the rotating block 7 can be pivotally connected in a rotatable manner. The left and right vertical plates of the rotating block 7 have abutting surfaces against the fixed seat 5, and the bottom corners of the abutting surfaces are provided with round chamfers to facilitate the rotation and flipping of the rotating block 7.

[0034] The handle 10 can manipulate the rotating block 7 to flip 90° with the round chamfer at its bottom as a fulcrum, so that the rotating block 7 has two states: horizontal and vertical. When the rotating block 7 flips from the vertical state to the horizontal state, the connecting pin 6 compresses the spring 9 and retreats horizontally outward under the traction of the rotating block 7. When the rotating block 7 flips from the horizontal state to the vertical state, the connecting pin 6 moves horizontally inward under the release of the spring 9. Preferably, the distance from the fixed pin 8 on the connecting pin 6 to the abutment surface on the rotating block 7 is smaller than the distance from the fixed pin 8 on the connecting pin 6 to the bottom surface of the rotating block 7.

[0035] Preferably, the screw 13 penetrates into the inner opening of the annular outer seat 4 from the bottom of the annular outer seat 4 and is connected to the fixing seat 5 above the annular outer seat 4, so that the fixing seat 5 is detachably and firmly installed on the annular outer seat 4.

[0036] Preferably, a guide groove is formed between the circular base 3 and the annular outer seat 4, and the push block 11 is located in the guide groove and performs linear sliding forward and backward.

[0037] Preferably, a wear-resistant gasket is provided at a portion of the fixed seat 5 that abuts against the rotating block 7 to improve the wear-resistant effect.

[0038] During the implementation of the utility model, the operator can use the thumb and index finger to apply force to the handle 10 to manipulate the rotating block 7 to flip 90 degrees with the round chamfer at the bottom as the fulcrum, so that the rotating block 7 has two states: horizontal and vertical. When the rotating block 7 flips from the vertical state to the horizontal state, the connecting pin 6 compresses the spring 9 and retreats horizontally outward under the traction of the rotating block 7, and the joint part of the optical fiber array 1 can be freely inserted at this time. When the rotating block 7 flips from the horizontal state to the vertical state, the connecting pin 6 moves horizontally inward under the release of the spring 9, and the inserted joint part of the optical fiber array 1 is clamped by the push block 11 on the connecting pin 6. The operator can complete the clamping of an optical fiber array within 3 seconds only by the action of the thumb and index finger, while compared with the prior art clamping method by screw fixing, it takes at least 12 seconds to complete the clamping of an optical fiber array, which can effectively improve production efficiency.

[0039] The above description is an explanation of the utility model, not a limitation of the utility model. The utility model can be modified in any form without violating the spirit of the utility model.
