Description
The present invention relates to a kind of device and a kind of novel new method that is used for blank is carried out cylindrical lapping of workpiece being carried out concentric cylindrical lapping.
Various these class devices that belong to prior art are arranged at present, especially when making the so-called metal cuff of so-called optical cable particularly importantly with metal ferrule end face that a counterpart is connected on the hole must accurately extend at the center.If proper alignment inaccuracy herein then will cause the power attenuation (being about to increase attenuation) that makes new advances on this interface.
Have two kinds to realize concentric scheme in principle: carry out concentric bore and reprocessing behind the external diameter of setting up the metal cuff, perhaps the boring back processes external diameter with one heart with the hole.
What the present invention relates to is second kind of preparation method, because this method is comparatively more favourable than first kind of preparation method.
The present invention with the content disclosed in the following document as prior art:
In US 5 862 280, disclosed the method for between two cone centres, a kind of cuff of specially-shaped being carried out cylindrical lapping, described cuff has a hole of extending therein and has thinner and a thicker diameter segment, and wherein an end also plays a part to transmit rotation and drives.Corresponding shaping recessed and the insert that cooperates be configured for jointly transmitting by the outside be added in moment of torsion on top profile be connected coupling.
To the installation optical cable time, the cable end of polishing is arranged on its certain side or the end face, and its mesopore must be accurately concentric with end face or external diameter, by the support of top taper realization to end face.And opposite side is used for engaging with rotating driving device.
Since must adopt certain axial compressive force to carry out clamping to cuff, thus on described end face, must be subjected to the effect of upset load or upset modification, and described upset load or upset modification will cause overlapping the cracked of hoop material in the rib scope of hole.The microstructure that usually will occur the hole rib under the effect of upset load occurs cracked, is asymmetric support and can meets the demands in no instance or invalid to the grinding of blank external diameter thereby cause by what taper realized.This point causes its end face and the end face that cooperates on the blank of completion of processing, for example bad connection of the plug connector of the optical cable of a connection.Distortion or the cracked aperture herein of causing owing to the hole rib also will change in addition, thereby cause the not good enough guiding of optical cable in the end face scope.
The solution of taking at these problems is must reprocess relevant end face, i.e. grinding again.But this point is the additional operation of not wishing to occur.In addition this grind again will cause the hole rib to the cuff third side to axial dipole field.Therefore will occur, when the hole of cuff inside concentric insufficient ,-as long as the proper alignment perfection of the outlet in end face and hole, then this names a person for a particular job and can not constitute problem ,-then corresponding with the end face of completion of processing hole exits is not concentric just.
In addition not only because clamping on lapping device can cause the cracked of hole rib microstructure, and to blank formerly be not best to end face scope or the processing on its hole rib yet.Taper is supported from the beginning and irrelevantly with the clamping load is asymmetric and is invalid to the proper alignment of hole axle just for the attrition process of blank cylindrical therefore.And will cause excessive expense and above-mentioned shortcoming to grinding again of end face in the case.
Except blank will be loaded, according to prior art also with the top very big load that causes relevant most employing hard material (for example diamond) is constituted.Relevant is top because best proper alignment (avoiding supporting the gap) is a rigidity setting, so the hole rib of blank rotates in top taper.Therefore the top wearing and tearing of feeling relieved also are very big.So top blank centering that no longer is applicable to other that is worn.Top grinding again is very expensive and often can not successfully finishes to diamond, thereby the centering of this costliness is top will improve processing cost.
JP-A-6-118273 has disclosed a kind of structure that similarly has corresponding clamping device.But so a kind of top support only is being different from above-mentioned prior art aspect the moment of torsion transmission.Substitute the coupling interlocking, also transferred torque on the cuff in this way by relative same male part ring bag at the polygon that forms on the cuff.In this invention, do not overcome described problem.
The similar structure that discloses according to JP-A-6-208042 is the support between top equally, and wherein the transmission of moment of torsion realizes by heart carrier.But do not overcome above-mentioned problem at this yet.
A kind of similar structure cognizing that discloses in JP-A-10-337664 has arrived the problems referred to above and has attempted to overcome in the following way these problems, with a kind of very expensive abutment pressure of the top minimizing of support on cuff.Except will paying very big support and expense cost for this reason, the moment of torsion problem of transmission will appear in this structure, and this problem is to solve by the compressing member that adopts on a side relative with abrasive disc.This names a person for a particular job to cause and occurs when driving sliding, thereby can not realize optimization to process of lapping.
Adopt rubber-surfaced roll to realize that the moment of torsion transmission also similar problem can occur according to the another kind of structure that discloses among the JP-A-10-113852, wherein also will add and have the above-mentioned problem that supports between top according to this prior art.
Deutsche Bundespatent 22656 (Patent Office of kingdom) is based upon on the basis of another program and at another purpose.This patent relates to a kind of clamping thimble that the outside of bore is ground.Wherein radially-directed spare separates with axial support.But relate to be-certainly in complete another field-similar purpose: should realize invariable wall thickness on the ad-hoc location at bore.This says the concentric structure that also will cause bore from theory, certainly exactly only in polished position.The basis of the processing method that is proposed not was by grind setting up concentric bore fully at that time, but by to the grinding of the annular groove processing to the annular extent of the identical relative narrower of wall thickness on this bore.Be necessary for the manufacturing procedure proceeded then in this scope with the bore clamping.In this prior art, continuous concentric cylindricalo grinding is not provided instruction.
At this purpose, can't cause the required concentric structure that on whole cuff length, has invariable concentric geometry to the application of the instruction of Deutsche Bundespatent 22656.Except above-mentioned, Deutsche Bundespatent 22656 is recognized in the problem of the aperture-deviation on the workpiece and proposed following solution: one plays the shape seat is being positioned at the workpiece roof pressure on the support member of abrasive disc side all the time.The end face of bore is inoperative in described process technology, and original at least end face should be best when cuff is ground, so that realize the purpose of cuff, is about to optical cable and positions with counterpart with one heart and fully identically.
According to JP-A-10-286748, when grinding to foreign round-identical with other situation of great majority-utilize pure taper or top be what impossible to realize the support of cuff.Realize radially-directed at this by one columniform, this cylindrical member is to mill realization by the inscribe in taper.The axial support of the necessity in this structure is to realize by a small-sized plane, and this small-sized plane is to adopt inscribe to mill realization.But in JP-A-10-286748, this small-sized ring surface is not made further instructions.Embodiment cylindrical part (or thimble) according to JP-A-10-286748 can be installed on the matrix of a pyramidal structure.
As Fig. 6 and 7 and in the Japanese patent specification shown in the corresponding explanation, what adopt that the support of flat anchor ring relates to is not the specific shape of axial support, avoids adopting taper to cause the cracked of hole rib and only relate to.Realized radially-directed by adopting the disclosed scheme of described Japanese patent specification will suppress taper to the damaging action of hole rib and by columniform part to cuff as useful side effect.
Owing to avoided the top application of taper, thereby in existing scheme, can not occur cracked and danger upset.And owing to be not to recline by the centering of taper on the rib of hole to produce radially guiding, thereby also reduced in the axial direction pressure to cuff by thimble.
But the disclosed device of Japanese patent specification has following potential problem: (mean value is about 0.5 μ m for the proper alignment of realization shown in Fig. 4 b; Or micron), the space between thimble and the workpiece must be especially little.Must not be greater than verified proper alignment 0.5 μ m.On the other hand in order to guarantee that thimble can also can rotate in the patchhole, must guarantee minimum gap again.This system only under the situation of verified precision, just works when promptly fit clearance is 0.5 μ m to the maximum.
But common cuff, even the tolerance in the hole of the single mode cuff that discloses in Japanese patent specification is 1.0 μ m.Thimble always is subjected to the certain wearing and tearing and the influence of bending stress in addition.
Wherein must consider since optical cable when bonding, even because bonding agent when causing vary in diameter, must be felt relieved again, the diameter tolerance tolerance limit in hole is littler than the influence of the position in hole or proper alignment to the influence of the quality of optical cable-connector.Adopt bonding agent can't realize compensation in contrast to concentric error.
For realizing cuff function preferably, also there is not more accurately to make at present the reason in cuff hole at present.That yes is necessary for this point, so that be embodied as the necessary fit clearance of instruction of using described Japan Patent.And, be economical anything but to the additional comparatively accurate screening that cuff carries out according to the aperture because the hole is measured obviously is one of the most expensive work in making the cuff process.
Based on above-mentioned prior art, the objective of the invention is to propose a kind of to workpiece, the simply more reliable centering bearing of cuff for example wherein on the one hand at least can be best and do not need the grinding that adds and measuring process ground to realize crucial end face and realize concentric grinding to the blank external diameter on the other hand under the condition of producing in batches.
The present invention and the known annular flat supporting surface of prior art different mining, axial supporting surface has the strong point of a little off-centre, the frictional force that the described strong point occurs based on its eccentric position with when supporting thereupon will cause the reaction force on cuff, and described reaction force can be realized the inconsistent compensation to the diameter that may exist between thimble or push rod and the hole.
The support of off-centre of the present invention will impel at identical position workpiece and the axial contact-making surface between supporting constant all the time, promptly do not rotate or uncontrolled moving can not occur, even when the end face of workpiece is not too smooth, also be like this.In addition to workpiece roof pressure (shearing between support, thimble and the workpiece) in the same direction always, thereby can eliminate in one direction gap.
Position by the strong point has guaranteed the side roof pressure of workpiece quilt to the power effect of abrasive disc.Even (reaching about 3 μ m) also can guarantee the grinding of invariable ground concentricity under the situation of 0.5 μ m when the gap between hole and thimble was big.
Therefore realized purpose of the present invention.
This according to solution of the present invention, with which kind of precision is led to the other end of blank or clamping is relatively not too important.Adopt the present invention also can realize flexible program in theory, wherein also can provide blank as bar as raw material, wherein after carrying out cylindricalo grinding, the first to bar the blank as bar can be cut off, so that then the next part of bar is carried out identical process.
Owing to adopted the present invention, thereby can process to the not so good blank of quality in the scope of quality critical.For example the structure of hole rib can inaccuracy, and the deviation of the holding state of aperture or thimble can not exert an influence.
In addition because the adjusting of thrust of having adopted the present invention thereby can having saved the complexity of blank clamping device.Also improved the security of working in addition, reduced percent defective and improved concentric quality.
Owing in support, be provided with through hole, can insert in the hole of cuff by this through hole thimble, so the flexible program that also can take separately according to the present invention can adopt the cheap push rod of expense.This point has been realized will changing thimble simply than hitherto known technical scheme.Because therefore thimble can be set back in the hole of support member, and be easy to take off workpiece, in addition by adopting this special flexible program to realize workpiece and the automation of taking off workpiece with being highly profitable.
In description of drawings and claim, provide further details of the present invention and design variant scheme.
The present invention is applicable to various cuffs in principle and does not need specially-shaped to cuff.Under any circumstance can save a procedure and improve machining accuracy.
