Description
Technical field
The present invention relates to a kind of cylindrical grinder of using such as the lateral surface grinding of the cylindrical work of optical fiber connecting elements to realize.
Background technology
Fig. 7 and 8 shows the structure of the known general example of finishing this type of cylindrical grinder that the grinding of a kind of lasso lateral surface uses.Among this cylindrical grinder M shown in the figure, elasticity transfer roller 4 presses against on the outer circumference surface of lasso F, and this lasso F then is that fixedly tailstock center 2 and mobile tailstock center 3 are supported with rotary way with one.Among the cylindrical grinder M of this structure, the elasticity transfer roller 4 that presses this lasso as mentioned above rotates, so lasso F also rotates the grinding outside just can carrying out with emery wheel 15 like this on lasso F.
The pressure that note that this elasticity transfer roller 4 must be adjusted and make and be set at a suitable value.This is because the variation slightly of this pressure of elasticity transfer roller 4 can have influence on the outside portion of this lasso F and the axiality that optical fiber inserts hole H (see figure 1), or the circularity in this lasso F outside, tapering or the like, promptly is to understand influential to the lateral surface grinding accuracy of this lasso F.
That is to say that the aperture of this lasso F (internal diameter of this fiber optic hub H) is 0.125 millimeter of (mm), then this point diameter of top 2 and 3 is littler.Because top 2 and 3 etc. are taper, can cause following point when pressing against elasticity transfer roller 4 on the lasso F outer peripheral face: (1) if the power that elasticity transfer roller 4 presses is too big, this is tailstock center 2 and just fracture or very quick-wearing easily of mobile tailstock center 3 fixedly.Also can such as unbalanced wearing and tearing, cause the inhomogeneities of this lasso F rotation, cause that the cylindricity of lasso F reduces because of the heel and toe wear of this quiet moving tailstock centre 2 and 3.(2) on the other hand, if the pressure of elasticity transfer roller 4 is too little, the frictional force between elasticity transfer roller 4 and lasso F outer peripheral face reduces, and lasso F just no longer can smooth rotation like this.The rotation that also can cause lasso F is irregular, causes the cylindricity of this lasso F to descend.So, be necessary the pressure of these elasticity transfer roller 4 usefulness is made adjusting, and make it to reach an optimum value.
Yet, be used as the above-mentioned adjusting of these elasticity transfer roller 4 pressure and set the experience and the intuition of normally pressing the operator.Promptly be, make this elasticity transfer roller 4 when it presses against the periphery of lasso F, on elasticity transfer roller 4, form a recessed position place of strain forward, then be decided to be a predetermined set value, adjust and set the used pressure of this elasticity transfer roller thus by the operator.In this process, for the recessed elastic deformation amount of this elasticity transfer roller 4 whether reached this predetermined value, this judgement is to be based upon on operator's experience and the intuition basis, so be difficult to make elasticity transfer roller 4 used throw-on pressures to be arranged to an optimum value.This pressure departs from optimum value can draw variety of issue, as the fixing fracture at tailstock center 2 and mobile tailstock center 3 decrease early, lasso rotates irregularly, and the circular shaft degree of this lasso that causes thus is bad or the like.
More particularly, as the used device of circular shaft degree that improves this lasso F, number be in 3171434 the Japan Patent, the grinding technique that this circular runout that can allow this elasticity transfer roller 4 on lathe is removed is disclosed, promptly be to remove the outer surface of this elasticity transfer roller 4 of grinding in order to the same emery wheel 15 of this lasso of grinding F outside grinding by this technology.When grinding elasticity transfer roller 4 is removed in this circular runout of application on lathe, the external diameter of this elasticity transfer roller 4 can reduce, therefore when elasticity transfer roller 4 presses against this lasso F outer peripheral face, the strain amount of recess of this elasticity transfer roller 4 then is changed, cause no longer and can this elasticity transfer roller 4 be pressed against on the outer peripheral face of this lasso F, the circular shaft degree of this lasso F is descended with the identical optimum pressure before removing grinding in this circular runout.
In addition, along with the process of cylindricalo grinding, the external diameter of lasso F can reduce gradually.So far, because of the lasso external diameter reduces, the strain amount of recess of this elasticity transfer roller 4 reduces, cause then such as the insufficient pressure of cylindricalo grinding final stage elasticity transfer roller and can make the rotation shakiness of lasso F, cause the circularity of lasso F bad.

The specific embodiment
Referring now to Fig. 1 to 6, describe an embodiment of cylindrical grinder of the present invention in detail.
Cylindrical grinder M as Fig. 1, has Double Tops apical branch bearing apparatus 1, and this Double Tops apical branch bearing apparatus 1 is to be made of two centers: fixedly tailstock center 2 and removable tailstock center 3, the grinding that is loaded in lasso F between this two center 2 and 3 and is cylindrical work, its outside is just pending.
This moment, lasso F wherein has been loaded in and has decided between tailstock center 2 and the moving tailstock center 3, should decide tailstock center 2 be to contact with the lasso fiber patchhole H of the end surfaces side direction of lasso F, be to contact and should move tailstock center 3 with the other end surface lateral lasso fiber patchhole H of lasso F.Meanwhile, lasso F is defeated to be against by a spring (not shown) and decides tailstock center 2, and this lasso F then is bearing on the Double Tops point of two centers 2 and 3 with rotary way.
Decide to be furnished with elasticity transfer roller 4 on the side of axial line line L-L of axial line at tailstock center 2 and moving tailstock center 3.
Promptly be in the beaming roller device 5, this place has the roll shaft 7 with rotating manner supporting, and this elasticity transfer roller 4 in a coaxial fashion integral installation in the rearward end of roll shaft 7.
When roller CD-ROM drive motor 6 starts, motor torque is transferred to roll shaft 7 one sides, so this elasticity transfer roller 4 rotates around roller axis with roll shaft 7 by actuating unit 8.
In addition, elasticity transfer roller 4 outer surface of this lasso F is relatively done the slip of front and back, and is maintained on the predetermined sliding position.This slide of elasticity transfer roller 4 and sliding position keep manipulation to be worked by drive units 10 (carriage) before and after the roller.
That is to say that in the cylindrical grinder shown in Figure 1, the whole roller device 5 that has comprised elasticity transfer roller 4, roller CD-ROM drive motor 6 etc. all is to be installed on the slide unit 11 of drive unit 10 before and after this roller.As shown in Figure 2, the slide unit 11 of drive unit 10 is connected on the piston rod 13 of reciprocating oil cylinder 12 before and after this roller, and can be seesawed on a device pedestal 14 by seesawing of piston rod 13.Just slide before and after the outer surface of lasso F relatively at this movement flexible transfer roller 4 on the device pedestal 14 by slide unit 11.
Moreover, the piston rod 13 of reciprocating oil cylinder 12 can stop on any position in the process that it seesaws.Rested by this of piston rod, can stop the motion of slide unit 11 then, elasticity transfer roller 4 is positioned and is retained on the predetermined slide unit position thus.
Promptly be, this roller front and back drive unit 10 makes relative lasso F be slip before and after the periphery, and plays carriage effect on a predetermined sliding position in order to location and maintenance elasticity transfer roller 4.
As shown in Figure 1, be furnished with emery wheel 15 on the opposite side of this moving surely tailstock center 2 and 3 axis line L-L.
With lasso F be intermediate, on a position relative with this elasticity transfer roller 4, emery wheel 15 is set, and in this place, the outer surface of this emery wheel is in abutting connection with the outer surface of lasso F.In addition, emery wheel 15 is around the outer surface of its axial line rotation with grinding lasso F.Emery wheel 15 is installed in the leading section of grinding wheel spindle (not shown), and has rotation by this grinding wheel spindle to make it be driven to rotate.
When carrying out cylindricalo grinding on lasso F as the emery wheel 15 of cylindrical grinder M among Fig. 1 of above-mentioned structure, this elasticity transfer roller 4 is pressed against lasso F is rotated, and the lasso F of this moment then is to decide tailstock center 2 and moving tailstock center 3 is supported with rotary way.Cylindrical grinder M shown in the figure has a device (pressure setting device 16) makes the pressure that this elasticity transfer roller 4 is set reach a fixing level.
For this pressure setting device 16, can be to be arranged at the fixedly various systems of level as throw-on pressure with elasticity transfer roller 4.In the pressure setting device 16 of cylindrical grinder M shown in Fig. 1, be one of the throw-on pressure of the elasticity transfer roller 4 wherein strain amount of recess that is set to this elasticity transfer roller 4 when the being pressed against lasso F outer surface fixedly the sort of applicable system on the level based on it.
That is to say that by this elasticity transfer roller 4 that a kind of elastomeric material is made, when being pressed against on the F outer peripheral face, the abutment surface of this elasticity transfer roller 4 has strain and understands an indentation part as shown in Figure 4 like that.The amount of recess of this strain is directly proportional with the throw-on pressure of elasticity transfer roller 4.So,, this means that it is a constant pressure that elasticity transfer roller 4 is pressed against lasso F outer surface if the measured value Δ X of the strain amount of recess of this elasticity transfer roller 4 is always identical when being pressed against lasso F outer surface.
Also have, this roller device 5 of being made up of the slide unit 11 of elasticity transfer roller 4 and roller advance and retreat drive unit 10 makes a global facility, causes the amount of movement that equals this slide unit 11 of the slippage of this elasticity transfer roller 4.
Like this, when being in wherein from a distance state of this elasticity transfer roller 4 and lasso F outer peripheral face, slide unit 11 is then also slipping over identical distance with this elasticity transfer roller 4 that makes progress towards lasso F reach, and this elasticity transfer roller 4 is then finally come with this lasso F periphery and contacted.
After this, slide unit 11 is further marched forward, 4 of this elasticity transfer rollers are pressed against on the outer surface of lasso F, and the front end of this elasticity transfer roller 4 (abutment surface) stands shell-shaped deformation then, and be pressed against because of the pressure effect on the outer surface of lasso F, and the front end of this elasticity transfer roller 4 (abutment surface) stands strain then, and because of the pressure effect is pressed into the pit shape, and that segment distance that this slide unit 11 is moved is then corresponding to the amount of recess Δ X of this strain.
So, by this elasticity transfer roller 4 begin to do strain by recessed instantaneous measured, promptly be the slippage (equaling the slippage of this elasticity transfer roller 4) that enters this slide unit 11 that begins to measure with lasso F outer peripheral face contacted moment from elasticity transfer roller 4, equal the amount of recess Δ X of the strain of this elasticity transfer roller 4.
Therefore, in the pressure setting device 16 of this cylindrical grinder M as shown in Figure 1, the strain amount of recess Δ X of elasticity transfer roller 4 is set at, by setting up on measurement result (amount of movement instantly of this slide unit 11) basis that is obtained by amesdial 16 one fixedly level.More particularly, the amount of movement of this slide unit 11 of surveying has just entered the instantaneous beginning that a contacts result as these slide unit 11 reaches with the outer outer surface of amesdial 17 own elasticity transfer rollers 4 and this lasso F, and when having reached a reference point already by amesdial 17 measured measurement results and be confirmed, promptly stop to move ahead of this slide unit 11.
Being suitable for the measuring system of this example, is to measure with 17 pairs of these slide unit 11 amount of movements of amesdial, and wherein measuring is that carry out at the rear portion of the slide unit 11 of drive unit 10 before and after this roller.
That is to say, in this measuring system, on the trailing flank of this device pedestal 14 of drive unit 10 before and after this roller, adopted a measurement, and the amount of movement of this slide unit 11 serves as with reference to being measured to measure reference plane S with reference to surface 5.
About above-mentioned reference system, among the cylindrical grinder M as shown in Figure 1, amesdial 17 is filled to this slide unit 11 by the middleware of a supporting member 18, and when adopting this mounting means, the leading section of the amesdial 17 gauge outfit 17-1 that released by spring (not shown) power is oppositely and against living in witness mark face S above-mentioned.
Like this, for example when slide unit 11 places in the position shown in the figure 1 the time, just refer to initial value " 0 " in the dial plate (not shown) so start the pointer 17-2 (see figure 3) of zero setting amesdial 17.After this, when slide unit 17 was shunk back on the direction of arrow in the drawings, amesdial 17 also returned in the same direction and removes with same distance.The gauge outfit 17-1 that is tried hard to recommend out amesdial 17 this moment by the spring (not shown) is to shrink back apart from a corresponding amount with this, and meanwhile, the pointer 17-2 of amesdial 17 is along with the motion of gauge outfit 17-1 is rotated.By the indicated dial plate reading (not shown) of pointer 17-2 correspondence the amount of shrinking back of slide unit 11 this moment.These also are applicable to the measurement situation of these slide unit 11 advance amount.
Next, the operation and so on of cylindrical grinder shown in Figure 1 is described with reference to Fig. 1 and 2.
(1) cylindrical grinder preparation
[1] with grinding the elasticity transfer roller is made eccentric correction
Among the cylindrical grinder M as shown in Figure 1, as make the circular runout of getting rid of elasticity transfer roller 4 in the cylindricalo grinding process, then need lathe before cylindricalo grinding begins, to finish the off-centre of proofreading and correct this elasticity transfer roller 4 with grinding method to realize improvement to lasso F out-of-roundness.In the grinding of this eccentric correction, the used same emery wheel 15 of employing and lasso F grinding comes the outer round surface of this elasticity transfer roller 4 of grinding.
[2] setting is to the depended on pressure of elasticity transfer roller
After this, in cylindrical grinder as shown in Figure 1, carry out a kind of necessity adjustment so that the depended on pressure of elasticity transfer roller 4 be set on the fixing level.
Now describe an embodiment of cylindrical grinder of the present invention in detail in conjunction with Fig. 1 to 6.
Cylindrical grinder M shown in Figure 1 has two conical sliding support devices 1, and this two conical sliding supports device 1 include two top: fixedly tailstock center 2 and mobile tailstock center 3, the lasso F that is loaded in two centers 2 and 3 is a cylindrical work, and its outside has to be ground.
The lasso F that is loaded in surely moving tailstock center 2 and 3 of this moment, wherein should be fixedly tailstock center 2 contact with lasso F fiber patchhole H on this lasso F one end surfaces side, this mobile tailstock center 3 then contacts with lasso F fiber patchhole H on this lasso F other end surface sides.Simultaneously, lasso F is pressed against this fixedly tailstock center 2 one sides by a spring (not shown) power, this lasso F then with rotary way be supported on two centers 2 and 3 two top on.
In this side of deciding tailstock center 2 and moving tailstock center 3 axis line L-L, be furnished with elasticity transfer roller 4.
This elasticity transfer roller 4 constitutes like this, and promptly its roller outer surface is pressed against the outer surface of lasso F and makes it apply torque to press the adjacency section like this and gives lasso F.This elasticity transfer roller 4 is made with the elastomeric material such as rubber in addition, rotates around the roller axial line and be suitable for it.
This elasticity transfer roller 4 can drive rotation with various systems.In this example, one of applicable system is rotated (see figure 2) for this elasticity transfer roller 4 wherein by a roller device 5 and roll shaft CD-ROM drive motor 6.
Promptly be, in this roller device, wherein provide the beaming roller 7 that supporting is rotated, and the elasticity transfer roller 4 that is installed to beaming roller 7 fore-ends with coaxial integral way.In addition, this beaming roller CD-ROM drive motor 6 is via by belt pulley, and the actuating unit 8 of compositions such as belt is received the rear end part of this beaming roller 7.
When shaft drive motor started, motor torsional moment was transferred to beaming roller one side by powered rotation device 8, so this elasticity transfer roller 4 rotates around the beaming roller axial line with beaming roller 7.
In addition, the elasticity transfer roller 4 outer surface front and back of lasso F relatively slides, and remains on the predetermined sliding position.The maintenance action of the sliding position of this sliding action and this elasticity transfer roller 4 realizes by drive unit 10 before and after the roller.
Promptly be, in cylindrical grinder M shown in Figure 1, comprise that the whole roller arrangement 5 of compositions such as roller CD-ROM drive motor 6 is installed on the slide unit 11 of this roller front and back drive unit 10 by elasticity transfer roller 4.As shown in Figure 2, the slide unit 11 of drive unit 10 is connected with the piston rod 13 of a reciprocating oil cylinder 12 before and after the roller, and rely on piston rod 14 seesaw one install can move reach on the pedestal 14 after.According to this motion of the slide unit 11 on device pedestal 14,4 slips of the outer surface work front and back of lasso F relatively of this elasticity transfer roller.
Moreover, in it seesawed process, the piston rod 13 of this reciprocating oil cylinder 12 can be parked in one arbitrarily on the position.By stopping of this piston rod 13, stop the motion of this slide unit 11 then, therefore, this elasticity transfer roller 4 is on a predetermined slide unit position.
That is to say that drive unit 10 makes elasticity transfer roller 4 relative lasso F outer surfaces do the front and back slip before and after this roller, and the effect of playing the location and keeping the carriage of elasticity transfer roller 4 on a predetermined sliding position.
As shown in Figure 1, the opposite side at this moving surely tailstock center 2 and 3 axis line L-L is furnished with an emery wheel 15.
The emery wheel position is to arrange like this, and it is by relative this elasticity transfer roller 4 of intermediate of lasso F, and on this position, the external peripheral surface of emery wheel is in connection with the outer surface of this lasso F.Emery wheel 15 is installed in the leading section of a grinding wheel spindle (not shown), and is driven rotation by the rotation of this grinding wheel spindle.
When with as the cylindrical grinder M of Fig. 1 when coming lasso F implementation grinding with the emery wheel 15 of aforesaid mechanism, this elasticity transfer roller 4 is pressed against lasso F is rotated, and this lasso is to be bearing in fixedly on the tailstock center 2 and mobile tailstock center 3 with rotary way.Cylindrical grinder M shown in the figure provides a device (pressure setting device 16) and reaches a fixedly level in order to the pressure that these elasticity transfer roller 4 usefulness are set.
About this pressure setting device 16, can be as this elasticity transfer roller 4 being set to the fixing various systems of level.In this pressure setting device 16 of the cylindrical grinder M shown in Fig. 1, these elasticity transfer roller 4 used throw-on pressures are set on the basis that fixing level is these elasticity transfer roller 4 strain amount of recess when being based upon it and being pressed against the outer round surface of lasso F in a kind of system that is suitable for.
That is to say that when this elasticity transfer roller 4 of being made by elastomeric material was pressed against lasso F outer surface, the abutment surface of elasticity transfer roller 4 promptly experienced distortion and is as shown in Figure 4 recessed.The amount of recess Δ X of this strain is directly proportional with the pressure of elasticity transfer roller 4.Therefore, if the strain amount of recess measured value of this elasticity transfer roller 4 is always identical when it is pressed against lasso F outer round surface, then mean it is the outer round surface that is pressed against lasso F with a constant compression force.
Moreover, the roller device 5 that includes elasticity transfer roller 4 and roller advance and retreat drive unit 10 slide units 11 is to make with single unit system, causes the slippage of this elasticity transfer roller 4 to equal the amount of movement of this slide unit.
Like this, when this elasticity transfer roller 4 wherein and lasso outer surface are in when separating state, this slide unit advances towards lasso F, and this elasticity transfer roller 4 is slipping over same distance in the same way, and this elasticity transfer roller 4 is finally come with this lasso F outer round surface and entered contacted position.
After this, allow slide unit 11 continue forward, this elasticity transfer roller 4 is pressed against the outer surface of lasso F then, and this elasticity transfer roller 4 front ends (abutment surface) experience strain and because of pressure becomes recess-like, 11 those segment distances that move simultaneously corresponding to this strain amount of recess Δ X of this slide unit.
Like this, the slippage of this slide unit 11 (equaling the slippage of this elasticity transfer roller 4) promptly as to begin to do recessed strain from this elasticity transfer roller 4 instantaneous, just, the outer surface of coming lasso F from this elasticity transfer roller 4 enters the instantaneous measured of contact, then is the elastic deformation amount's Δ X that equals this elasticity transfer roller 4.
In this case, as shown in Figure 1 in the pressure setting device 16 of cylindrical grinder M, the strain amount of recess Δ X of this elasticity transfer roller 4 then is set at one on measurement result (the instant amount of movement of this slide unit 11) basis that is obtained by this amesdial 16 fixing level.More particularly, as slide unit 11 advance the result, enter the moment that contacts has been measured this slide unit 11 by amesdial 17 amount of movement from this elasticity transfer roller 4 and lasso F outer surface, and be when being proved this measurement result that is obtained by this amesdial 17 and having reached a reference point, advancing of this slide unit 11 stops.
For with amesdial 17 to slide unit 11 amount of movements, the measurement that is suitable for being adopted in the measuring system of present embodiment is the rear portion of the slide unit 11 of drive unit 10 before and after this roller.
Promptly in this measuring system, be used as the reference plane S of measurement with the rear side surface of the device pedestal 14 of drive unit 10 before and after this roller, and the amount of movement of this slide unit 11 records with reference to the surperficial S of this measurements reference.
About above-mentioned measuring system, among the cylindrical grinder M shown in Figure 1, this amesdial 17 installs on the side of slide unit 11 by the intermediary of supporting member 18, and in the cylindricalo grinding process under this installment state, these amesdial 17 gauge outfit 17-1 leading sections measurement reference plane mentioned above vis-a-vis S that tries hard to recommend out by a spring (not shown) and adjacency with it.
So, when for example this slide unit 11 is in position shown in Figure 1, carries out and set initial value " 0 " (not shown) that the pointer 17-2 (see figure 3) that makes amesdial 17 is pointed to dial plate.After this, slide unit 17 is when the direction of arrow is shunk back in by figure, amesdial 17 also at retraction in the same way by identical distance.Meanwhile, the gauge outfit 17-1 of this amesdial 17 by a spring (not shown) try hard to recommend out corresponding to this retraction distance a corresponding segment distance, this pointer 17-2 of amesdial 17 rotates with the motion of gauge outfit 17-1.The situation that the dial plate reading (not shown) by pointer 17-2 indication of this moment is then measured corresponding to these slide unit 11 advance amount.
Subsequently, with reference to Fig. 1 and 2 in detail cylindrical grinder shown in Fig. 1 and similar device and operation are described in detail.
(1) preparation of cylindricalo grinding
[1] adopt grinding to remove the resilient roller shaft run-out
In cylindrical grinder shown in Figure 1, improve cylindricity in this lasso F cylindricalo grinding for making realization by the circular runout of removing this elasticity transfer roller 4, then need finish the eccentric correction grinding dressing before lathe carries out cylindricalo grinding to this elasticity transfer roller 4.In this eccentric correction grinding, used same emery wheel 15 comes the outer round surface of this elasticity transfer roller 4 of grinding in employing and this lasso F cylindricalo grinding.
[2] to the setting of elasticity transfer roller depended on pressure
Subsequently, in cylindrical grinder shown in Figure 1, finish these elasticity transfer roller 4 depended on pressure being set a fixedly necessary adjustment operation of level.
In this adjustment process, to allow before this support this lasso F by the fixing two top places at tailstock center 2 and mobile tailstock center 3, this elasticity transfer roller 4 is contacted with lasso F outer surface.The instantaneous amount of movement of reinstating amesdial 17 measurement slide units 11 that begins to work from contact.
Yet when allowing slide unit 11 continue forward, these elasticity transfer roller 4 front ends (abutment surface) that contact with lasso F outer surface stand strain and become recessed.When this strain amount of recess Δ X arrives a fixing setting value, stop slide unit 11 and advance, and be read out by the numerical value on the indicated dial plate of amesdial 17 pointer 17-2.Reading value on this dial plate then corresponding make from this lasso F outer surface and elasticity transfer roller 4 just now and enter the instantaneous amount of movement that records slide unit 11 that contacts mutually, promptly be the strain amount of recess Δ X of this elasticity transfer roller 4, and this numerical value just be used as be adjust the reference point of throw-on pressure to a predetermined set value of this elasticity transfer roller 4 and setting and with the cylindricalo grinding of after this instructing this lasso F.
(2) cylindricalo grinding
Among the cylindrical grinder M as shown in Figure 1, during the actual cylindricalo grinding of carrying out lasso F, opposite (after this, mention this rotating to be " normality rotation ", and rotate to be in contrast to this " counter-rotating ") of these elasticity transfer roller 4 direction of rotation and emery wheel 15.In addition, because slide unit 11 forward, this elasticity transfer roller 4 is satisfied and can be entered contacting a little with lasso F outer surface.Then, from then on the amount of movement of this slide unit 11 promptly begins to charge to measurement by amesdial 17 forward moment.
Then, allow slide unit 11 continue forward, this elasticity transfer roller 4 is pressed against on the outer surface of lasso F then.In this process, when the measurement result (this slide unit 11 amount of movement instantly) that is obtained when this amesdial 17 reaches that reference point of obtaining in the above-mentioned beamhouse operation of describing (being brought to the amount of movement of this measured when entering the moment that contacts each other slide unit 11 from lasso F outer peripheral face and elasticity transfer roller 4), allow advancing of slide unit 11 stop.
Because this arrangement, elasticity transfer roller 4 front ends press against lasso F outer surface will be in beamhouse operation, always be in an identical position, and since pressure be with beamhouse operation in the strain amount of recess Δ X of identical, this elasticity transfer roller 4, its representative be in beamhouse operation through the throw-on pressure of the elasticity transfer roller 4 adjusted, and be set at a basic with it predetermined value that equates.
Yet, in cylindrical grinder M shown in Figure 1, adjust and set after this elasticity transfer roller 4 pressure to a predetermined value with amesdial 17, the outer round surface cylindricalo grinding of carrying out lasso F with emery wheel 15, as described above.
Like this, in cylindrical grinder M shown in Figure 1, even carrying out the footpath to elasticity transfer roller 4 of pressing beamhouse operation (1) on lathe jumps when proofreading and correct grinding, also can set the throw-on pressure of elasticity transfer roller 4 to optimum value with amesdial 17, and need not as in the prior art, rely on operator's experience and intuition, also can prevent simultaneously because of pressure depart from that optimum value causes such as, fracture, early decrease, fix and the heel and toe wear of mobile tailstock centre 2 and 3 and the problems such as irregular rotation of lasso F, thereby realize the relevant cylindricity of lasso F is improved.
At this, the fiber patchhole H of this lasso F, inject it that also contact with it with fixing tailstock center 2 and mobile tailstock center 3, script is used as the insertion optical fiber and adheres on it, and be not to be to do to insert and mesh usefulness with moving surely tailstock centre 2 and 3, cause in some cases, not really suitable after moving surely tailstock centre 2 and 3 injects fiber optic hub H, clamp like this and will be unstable by the lasso F of top 3 supportings.
When this thing happens, the elasticity transfer roller had just entered with lasso F outer peripheral face and has contacted, and lasso F begins will put upside down the direction of rotation of this elasticity transfer roller 4 after the rotation, made the reverse that turns to of lasso F.Promptly be, this turns to and is changed, by normality to reverse or reverse to normality.At this moment, if lasso F begin to rotate with emery wheel 15 and workpiece between enter between contacting during this period of time in realize this reverse, not qualification of wherein relevant this timing that is reversed.In addition, above-mentioned during this period of time in, carry out to turn to that to put upside down can be any number of times.Then, caused wherein that elasticity transfer roller 4 is forced into lasso F outer surface to the predetermined value operation carrying out above-mentioned adjustment and pressure is set, this elasticity transfer roller 4 is rotated on the normality direction.
When the above-mentioned operation of elasticity transfer roller 4 rotations was put upside down in execution, because of putting upside down of rotating, turning to also of this lasso F was reversed.By utilizing the way that reverses operation can make this fixedly accurately insert this fiber patchhole H with mobile tailstock center 3 and accurately contact in tailstock center 2 in this place, it is believed that, lasso F wherein can be more stable with top 2 and 3 clamping and supporting, thereby realized the improvement of relevant lasso F cylindricity.
(3) points for attention in making the set-up procedure of cylindricalo grinding
In the preparation (1) of above-mentioned cylindricalo grinding, this elasticity transfer roller 4 is pressed against on the outer surface of lasso F.In this process, elasticity transfer roller 4 should be to get at the outer surface that is pressed against lasso F under its axis rotary state.Doing like this is in order to realize by the improvement of cylindricalo grinding to lasso F cylindricity.
Promptly be, when the elasticity transfer roller 4 under the inactive state is directly pressed to lasso F outer surface, because of a kind of recessed of pressure formation also can form at these elasticity transfer roller 4 sides similarly.The recessed meeting that causes like this makes, and is irregular such as the rotation of this lasso F, so the rotation precision of this lasso F descends, this then is quite similar with the lasso F cylindricity deterioration that is caused by cylindricalo grinding.In contrast, wherein in the above-mentioned layout under rotation status elasticity transfer roller 4 is pressed against on the outer round surface of lasso F, the adjoining position of this elasticity transfer roller can be invariable in these elasticity transfer roller 4 pressure setting up procedure so, cause owing to can on the side of elasticity transfer roller 4, not forming because of the recessed of pressure, thereby, therefore realized the improvement of relevant lasso F cylindricity because of the deterioration of this recessed lasso F running accuracy aspect that causes is prevented.In view of this, in cylindrical grinder as shown in Figure 1, in making above-mentioned preparation (1) process, this elasticity transfer roller 4 is to get on the outer round surface that presses against lasso F under rotary state.
At this, as the used pressure setting device 16 of this elasticity transfer roller 4, emphasis considers it is its strain amount of recess when being pressed against lasso F outer surface when elasticity transfer roller 4, and a kind of layout in just being suitable among the cylindrical grinder M as shown in Figure 1, this for to make this elastic deformation amount equal effective setting of reference point, it also can be replaced by a kind of suitable pressure setting device 16 as illustrated in Figures 5 and 6.
