Description
Technical field
The utility model relates to a kind of optical fiber cleaver, and it comes cutting optical fibre by using the disk blade parts to form otch on the surface of the glass optical fiber part of optical fiber.
Background technology
" stress fracture " method is the method that silica-based optical fiber is cut in known being used to.
This stress fracture method is a kind of like this method: at first form initial incision by the adamantine cutting blade of being made by superhard alloy or adamas etc. that is used to form otch on the surface of the glass optical fiber part of optical fiber, subsequently glass optical fiber is partly applied bending stress so that make fibercuts, thereby promptly on the section of optical fiber, obtain minute surface by splitting.
According to this method, can not use the cutting surface of grinding optical fiber such as grinding stone and form minute surface apace.Therefore, in the building site and the laboratory, this method can connect multiple optical cable effectively.
Developed a kind of like this device as the optical fiber cleaver of carrying out this stress fracture method, it is partly mobile towards the glass optical fiber of optical fiber with the disk blade parts that this device construction becomes, and form otch on the surface of this glass optical fiber part.
Yet, be configured to use on the glass optical fiber part surface of blade part at optical fiber in the device that forms otch this, when reusable blade part rust, the profile of optic fibre that breaks to form that produces is not good minute surface by splitting.
Correspondingly, propose a kind of like this optical fiber cleaver: wherein the disk blade parts are installed as when unclamping the screw that is used for the tightening tools chip part and can rotate freely, and before the blade part rust, the operator of device unclamps blade part, and make blade part center on the suitable angle of its disc centre rotation, so that change the contact area of blade part and glass optical fiber part.
Yet there is following problem in the device of this correlation technique.That is it is heavier that, the rotating blade parts change the burden that the operation of contact area between blade part and the glass optical fiber part makes the operator bear.In addition, the frequency of contact area changes along with the operator between change blade part and the glass optical fiber part.Therefore, be difficult to suitably to change contact area between blade part and the glass optical fiber part.
Correspondingly, for fear of this problem occurring, the optical fiber cleaver shown in Figure 13 A and Figure 13 B has been proposed.
Shown in Figure 13 B, in optical fiber cleaver 100, gear 113 is arranged on the side of blade part 107 integratedly.Gear 113 and first leaf spring 115 of driven wheel and second leaf spring, 117 engagements that are used to prevent the gear reverse rotation.
When block part 111 fell, first leaf spring 115 was pushed downwards by operative pin 119, and this operative pin 119 is arranged on the cardinal extremity of block part 111 regularly.Gear 113 is along the rotation of the direction of arrow R shown in Figure 13 B predetermined constant angle.Because gear 113 is one with blade part 107, so blade part 107 rotates the predetermined constant angle integratedly with gear 113.Therefore, changed the contact area of blade part 107 with glass optical fiber part 103.
That is, in the optical fiber cleaver 100 shown in Figure 13 A and Figure 13 B, blade part 107 synchronously rotates the predetermined constant angle automatically with the descending motion of block part 111, so that the glass optical fiber part 103 that is formed with otch on it is split.Like this, changed the contact area of blade part 107 with glass optical fiber part 103.Correspondingly, can change the contact area of blade part and do not increase operator's burden.In addition, can reduce the variation that contact area changes frequency.
Simultaneously, in optical fiber cleaver 100, by blade part 107 rotations are changed the contact area of blade part 107 and glass optical fiber part 103 corresponding to the predetermined angular of (1/12) of for example circumference at every turn.Yet, consider the processibility and the manufacturing cost of the gear 113 that is used for rotating blade parts 107, there is lower limit in the predetermined constant angles of blade part 107 each rotations.
Therefore, in the optical fiber cleaver 100 of correlation technique, the each length that changes of contact area is longer relatively.Correspondingly, change the number of times existence restriction of the contact area of blade part 107.Therefore, there is the problem in the life-span that is difficult to prolong blade part 107 in the optical fiber cleaver 100 of correlation technique.

Optical fiber holder 17 has and is used for from the pedestal 21 of supported underneath optical fiber holder 17 and is used for optical fiber 15 is pressed in pressing plate 22 on the pedestal 21.
The location of optical fiber holder 17 is carried out in optical fiber mounting portion 19, thereby makes glass optical fiber part 16 that the end of the optical fiber 15 that keeps from optical fiber holder 17 exposes intersect with the mobile route (i.e. the path of being represented by arrow X shown in Figure 2) of blade part 3 above lower casing 5.
With the mode supported framework 11 that the direction that can represent along arrow X shown in Figure 2 moves, this support frame 11 rotatably supports plate-like blade part 3.Shown in Fig. 4 A, when the end face 11a that exposes from the side of lower casing 5 when support frame 11 was subjected to pushing, this support frame 11 slided along the direction of pushing end face 11a.Blade part 3 moves integratedly with support frame 11.
To shown in Fig. 4 D, spring members 13 is arranged on the opposite side of support frame 11 as Fig. 4 A, and is used for along the direction pushing support frame 11 that support frame 11 is pushed back.
Shown in Fig. 4 B, sliding support framework 11 makes blade part 3 (promptly as described below above otch formation position P when pushing also, blade part 3 and the glass optical fiber part 16 in the optical fiber contact and form the position of otch) time, support frame 11 engages and is fixed on this position with extension locking mechanism (not shown) in being arranged on lower casing 5.
Shown in Fig. 4 B, after blade part 3 surpasses otch formation position P and fixes, shown in Fig. 4 C, will keep the optical fiber holder 17 of optical fiber 15 to be set on the optical fiber mounting portion 19.Thus, glass optical fiber part 16 is positioned at otch and forms P place, position.
When the position that is in shown in Fig. 4 C, upper casing 9 is (that is, upper casing 9 is turned to lower casing 5 and be pressed on the upper surface of lower casing 5) of closing, and is arranged on joint on the upper casing 9 and removes the part (not shown) and remove support frame 11 and hang joint between the locking mechanism.Therefore, the pushing force of spring members 13 makes support frame 11 fast returns to initial position.This moment, the move operation of blade part 3 made the cutting edge of blade part 3 contact with glass optical fiber part 16, and formed otch on glass optical fiber part 16.
In according to optical fiber cleaver 1 of the present utility model, with the move operation that is used to form otch of blade part 3 rotating blade parts 3 synchronously.Change the contact area of blade part 3 and glass optical fiber part 16 thus.
The mechanism that is used to blade part 3 and its move operation are synchronously rotated is constructed as follows.
In the move operation that is used to form otch of blade part 3, realize by the contact friction force that contact produced between blade part 3 and the contact component 27 that blade part 3 moves synchronously with it and rotate that contact component 27 is arranged in the mobile route of blade part 3 regularly.
As shown in Figures 2 and 3, blade part 3 comprises: send into roller 31, it is configured to by contacting with contact component 27 and accepting contact friction force and rotate; And one-way clutch 33, it only is configured to will send into the moment of torsion of roller 31 be delivered to blade part 3 when specific direction rotates when sending into roller 31, thereby makes blade part 3 rotations.
In the present embodiment, one-way clutch 33 embeds the interior circumferential portion of sending into roller 31.The output shaft of one-way clutch 33 is fixed on the central shaft of blade part 3.
Send into the contact area between roller 31 and the contact component 27 and act between the two contact pressure by regulating contact component 27 and send into roller 31 position contacting, can changing.Therefore, can regulate the size of sending into the contact friction force between roller 31 and the contact component 27.
In the present embodiment, to shown in Fig. 4 D, the set positions that is provided with of contact component 27 is the direction that moves along blade part 3 and the otch formation position preset distance of being separated by as Fig. 4 A.Therefore, pushing support frame 11 make send into roller 31 and form position P by otch after, form the position of position P departing from otch, make blade part 3 owing to the contact friction between contact component 27 and the blade part 3 is rotated.
Then, in optical fiber cleaver 1, shown in Fig. 4 D, move the cleaning device 35 that setting contacts with blade part 3 in the path of returning, be used for the surface of cleaning blade parts 3 at blade part 3 according to present embodiment.
In above-mentioned optical fiber cleaver 1, synchronously make blade part 3 rotations with the move operation that is used for the blade part 3 of formation otch 24 on glass optical fiber part 16.Like this, the contact area between blade part 3 and the glass optical fiber part 16 automatically changes.
Therefore, can automatically change the contact area between blade part 3 and the glass optical fiber part 16, and not increase operator's burden.
In addition, in optical fiber cleaver 1 according to present embodiment, realize the rotation of blade part 3 by contact friction force, above-mentioned contact friction force produces by blade part 3 and the contact that is arranged on regularly between the contact component 27 in the mobile route of blade part 3.
Like this, at the move operation of the blade part 3 that is used on glass optical fiber part 16 forming otch 24, contact component 27 is going on journey and the return and is sending into roller 31 and contact.Yet owing to be provided with one-way clutch 33, blade part 3 only can go rotation on one of journey and return.Therefore, even the direction of the contact friction force on the direction of going to act on contact component 27 on the journey and send into the contact friction force between the roller 31 and return is opposite, can not make blade part 3 reverse rotations yet.Therefore, blade part 3 can be suitably along a direction rotation.
In addition, according to the selection of the direction of operating of one-way clutch 33, can determine that blade part 3 is to remove Cheng Xuanzhuan or rotating on return.
In the above-described embodiments, blade part 3 rotates on the journey going.Therefore, guarantee that blade part 3 rotates owing to contact component 27 and the contact friction force sent between the roller 31.Yet, can adjust blade part 3, make when blade part 3 because the thrust of spring members 13 and on return, return and rotate when mobile.Adopt such structure, in order to send into roller 31 because the thrust of spring and fast return can obtain contact friction force when moving reliably, preferably, contact component 27 applies elastic force by leaf spring etc. to sending into roller 31.
In addition, in the optical fiber cleaver 1 according to present embodiment, contact component 27 is fixed in the mobile route of blade part 3 by position adjusting mechanism 28, position adjusting mechanism 28 is used to regulate contact component 27 and sends into contact friction force between the roller 31.Be adjusted in a small amount to the rotation amount of smaller value by the size adjustment of use location governor motion 28 blade part 3 with contact friction force.
Therefore, can increase the maximum change number of times of the contact area of blade part 3.Correspondingly, can prolong the life-span of blade part 3.
In addition, optical fiber cleaver 1 according to present embodiment, position adjusting mechanism 28 can be regulated the position of contact component 27 on three directions, and these three directions comprise: the moving direction (being the directions X shown in Fig. 2) of the direction of the rotation of blade part 3 (being the Y direction shown in Fig. 2), the blade part 3 vertical with the rotation direction of blade part 3 and with the rotation and all vertical direction (being the Z direction among Fig. 3) of the moving direction of blade part 3 of blade part 3.
Like this, by regulate the position of contact component 27 along the direction of the rotation of blade part 3, contact component 27 and the contact width of sending between the roller 31 can be adjusted to arbitrary value.In addition, by adjust the position of contact component 27 along the moving direction of the blade part vertical 3, contact component 27 and the contact length of sending between the roller 31 can be adjusted to arbitrary value with the rotation of blade part 3.By along adjusting the position of contact component 27, contact component 27 and the contact pressure of sending between the roller 31 can be adjusted to arbitrary value with all vertical direction of the moving direction of the rotation direction of blade part 3 and blade part 3.The combination that corresponds respectively to the adjusting of these three directions by position adjusting mechanism 28 can increase contact component 27 and send into the range of adjustment of the contact friction force between the roller 31, and can finely tune contact friction force.For example, the rotation amount of blade part 3 that is used to change the contact area of blade part 3 is set at minimum value, so that prolong the serviceable life of blade part 3.In addition, can recover the contact friction force that the abrasion owing to contact component 27 reduces.
Incidentally, consider the length that blade contacts with glass optical fiber part 16 and the life-span of blade part 3, preferably, the rotation amount of blade part 3 is set at 5 appropriate values of spending in the scopes of 35 degree during with the contact area that changes blade part 3 at every turn.Like this, under the situation that the rotation amount of blade part 3 is restricted when the contact area of each change blade part 3, the length of each contact area that changes can be not excessive.Therefore, the contact area number of times that need change is in 10 to 72 scope.Therefore, can change contact area by the rotation of blade part, thereby prolong the life-span of blade part reliably.
More particularly, the rotation amount of blade part is set under the situation of 15 degree at every turn in the time will changing, and contact area can be changed 24 times.As a result, can prolong the life-span of blade part 3, keep blade part 3 very sharp simultaneously.
In addition, in optical fiber cleaver 1, can make blade part 3 owing to the contact friction force between contact component 27 and the blade part 3 rotates in the position of departing from otch formation position P according to present embodiment.
Like this, making blade part 3 form position P with glass optical fiber part 16 at otch under the static state of blade part 3 contacts.Therefore, can form otch accurately.In addition, can reduce the damage of blade part 3.
In addition, in optical fiber cleaver 1, shown in Fig. 4 D, in the mobile route of blade part 3, be provided with the cleaning device 35 that contacts with blade part 3, be used for the surface of cleaning blade parts 3 according to present embodiment.
Correspondingly, even the chip that produces when forming otch on glass optical fiber part 16 also can remove attached to the chip on the blade part 3 by the clean operation by cleaning device 35 before otch forms operation attached on the blade part 3 next time.Therefore, the chip that remains on the blade part 3 can not influence the operation of otch formation next time.
Next, description is according to second embodiment of optical fiber cleaver of the present utility model.Fig. 5 is the planimetric map that illustrates according to the body of second embodiment of optical fiber cleaver of the present utility model.Fig. 6 is the view that the direction along arrow B shown in Figure 5 obtains.

The pitch of tooth 41 that incidentally, can be by changing gear 37 and change the rotation amount of blade part 3 according to gear 37.Optionally, can be set at anisotropically by pitch and change, to change the rotation amount of blade part 3 tooth 41 of single gear 37.
Similar to first embodiment, in this case, the rotation amount of blade part 3 is set at 5 appropriate values of spending in the scopes of 35 degree during with the contact area that changes blade part 3 at every turn.The length of the contact area that changes can be not excessive like this, at every turn.Therefore, the maximum of the contact area of blade part can be changed number of times and be set at enough big numerical value.Correspondingly, prolonged the life-span of blade part.
In above-mentioned optical fiber cleaver 1A, by being omitted in the one-way clutch that uses among first embodiment, the simplification that can the implement device structure and the reduction of manufacturing cost.
In addition, in optical fiber cleaver 1A according to second embodiment, can realize the rotation of blade part 3 by contact between gear 37 and the arm member 39 or Elastic Contact, gear 37 forms with blade part 3, and arm member 39 is arranged in the mobile route of blade part 3 regularly.Therefore, rotating blade parts 3 reliably.
In addition, in above-mentioned two embodiment, blade part 3 rotates on the journey in mobile going.Then, when blade part 3 was mobile on return, the contact area of the change by blade part 3 formed otch on the surface of glass optical fiber part.Like this, be about to carry out before forming the operation of otch on the surface of glass optical fiber part the contact area of change blade part 3 at every turn.Therefore, can form otch by the blade part of sharp edges.
