Description

The Ginding process of the endless belt metal rings of buncher and device thereof

Technical field

The present invention relates to a kind of to using the laminal becket on the endless belt of buncher to carry out abrasive method and device thereof.

Background technology

For example, the band that the transmission of power that buncher adopted is used has used by stacked ring and has tied up the assembly that a plurality of elements with the ring-type stacked arrangement form, and wherein this stacked ring becomes to form by stacked a plurality of beckets.Constitute the becket of this stacked ring, be by thin discoideus emery wheel with metallic cylinder cylindraceous in accordance with regulations width cut into annulus, form the non junction band shape.And, jagged because the becket that is cut down by cylinder cylindraceous produces at the side edge, so must grind to its burr.In addition, even the burr that produces at the side edge of becket is less, also must the side edge of becket be ground, so that the side edge is processed into high-precision curved shape.

As everyone knows, as the method for the side edge of abrasive metal ring in the past, for example, disclose the spy and open method in the 2001-241512 communique.The Ginding process of this becket is called as barreling, and it is the becket as workpiece to be mixed into be full of in the cylinder that the emery wheel that is known as medium is arranged, and becket is rotated with cylinder with medium.Like this,, and make medium be contacted with the side edge of becket by agitated medium and becket together in cylinder, thus the side edge of abrasive metal ring.

Yet, when carrying out the occasion of barreling,, therefore, can produce the inboard bight of side edge of becket and the grinding in bight, the outside and present uneven problem because the medium of the outer peripheral face side institute butt of becket will be more than an inboard side.In addition, when putting into becket in the cylinder, and when barreling, might produce damage because of colliding between the becket.Becket although it is so can be removed by checking, still, this will become the reason that reduces yield rate.

On the other hand, open in the 2002-248522 communique, disclose method by the side edge of abrasion wheel grinding becket the spy.Yet, the grinding of being undertaken by emery wheel, can because the shape of the side edge of becket by the shape of emery wheel institute about, therefore, must carry out the replacing of emery wheel etc. continually, thereby produce the problem that operating efficiency reduces.

Summary of the invention

Address this problem, the objective of the invention is to,, provide a kind of and do not carry out barreling or grind, just the Ginding process and the device thereof of the becket that can grind the side edge of becket by emery wheel in order to solve the above problems.

In order to achieve the above object, method of the present invention is that the becket that uses the thin plate tubular on the endless belt of buncher is carried out abrasive method, it is characterized in that having: put into operation, put into described becket; The 1st brush grinding step grinds by the side edge of abrasive brush to the becket putting into operation at this and be placed into; The upset operation makes the becket upset of having been ground a side edge in the 1st brush grinding step; The 2nd brush grinding step grinds by the opposite side ora terminalis of abrasive brush to the becket that has been reversed in this upset operation; And send operation, will in the 2nd brush grinding step, have been ground the becket of opposite side ora terminalis and sent.

According to Ginding process of the present invention, at first, by described the 1st brush grinding step, side edge to becket grinds, then, and by described upset operation, make becket upset,, the opposite side ora terminalis of becket is ground by described the 2nd brush grinding step.Because described the 1st brush grinding step and described the 2nd brush grinding step are to grind by the side edge of described abrasive brush to becket, therefore, barreling different from the past does not have emery wheel and is attached on the ring surface, grinds thereby can carry out high accuracy.And, by described upset operation is set, a side edge and the opposite side ora terminalis of abrasive metal ring expeditiously.

And, in described the 1st brush grinding step and described the 2nd brush grinding step of method of the present invention, becket remained circular and make it and rotate at the circumferencial direction of described becket, and make and form its diameter and be connected to this becket in the mode of the ora terminalis of the becket that passes across rotation greater than the ring-type of becket and the abrasive brush that can rotate, when this abrasive brush passes across the ora terminalis of becket of rotation, this abrasive brush is with 20 ° to 45 ° incidence angle for the track of the becket of described rotation, enter the inside of this becket, and between the center of rotation of the inner peripheral surface by this becket and this becket, leave described becket with 20 ° to 45 ° receding angle for the track of this becket then.

Described incidence angle and described receding angle, therefore, must improve the speed of abrasive brush or prolong milling time because the amount of grinding of the side edge of becket tails off if do not reach 20 °.In addition, described incidence angle is not if reach 20 °, the inner peripheral surface that abrasive brush will the butt becket, thus cause inner peripheral surface all will to be ground.On the other hand, incidence angle and receding angle then have only the top of the side edge of becket to be ground if surpass 45 °, can't carry out preferable chamfering like this.So, by making that described abrasive brush is 20 ° to 45 ° with respect to the incidence angle and the described receding angle of becket, can carry out the preferable chamfering of the side edge of described becket.

In addition, in the method for the invention, put into the described becket that operation is placed into, preferably before this puts into operation,, the metallic cylinder of thin plate tubular cut into the disk shape forms earlier by set cutting action described; In this cutting action, be to come the described metallic cylinder of crush-cutting by the cutter that the sword face is peak shape.

Because if as in the past, cut out becket by the discoid emery wheel cutting metal of thin plate cylinder, the side edge cross section of becket then be a square shape, therefore, from this state the side edge of becket is carried out the just necessary increase allowance of chamfering.In the present invention, owing to be to come crush-cutting to go out described becket by the cutter that its sword face is a peak shape, so the side edge of becket is transferred the shape of this cutter and presents the state of chamfering.So, compare with the occasion of cutting by emery wheel like that in the past, can reduce allowance.

In described the 1st brush grinding step and described the 2nd brush grinding step of method of the present invention, when abrasive brush is connected to becket, detect the load current value of the motor that drives this abrasive brush rotation, so that this detected load current value reaches the mode of the load current value of predefined prescribed limit, increase and decrease the approach of abrasive brush to becket.

In described the 1st brush grinding step and described the 2nd brush grinding step, grind as expression control shape abrasive power the motor rotation axis moment of torsion substitute characteristic, load current value corresponding to detecting from the motor that drives abrasive brush increases and decreases the approach of abrasive brush to becket.That is, in abrasive brush rotates, be connected to the side edge of becket and when grinding, abrasive brush imposes load to motor.The load that motor is born is as the load current value of motor and be detected.At this moment, when abrasive brush was big to the approach of becket, load current value was also bigger, and abrasive brush to the approach of becket hour, and load current value is also less.On the other hand, if abrasive brush is bigger to the approach of becket, then become greatly by the amount of grinding of abrasive brush to the side edge of becket, if approach is less, amount of grinding then diminishes.So if the load current value of motor is bigger, it is bigger then can to confirm as amount of grinding, if the load current value of motor is less, it is less then can to confirm as amount of grinding.In view of the above, can preestablish: the scope (load current value of prescribed limit) that can access the load current value of better grinding amount.

And, for example, when abrasive brush weares and teares, because the load current value of motor reduces, so by abrasive brush is increased the approach of becket, even worn out abrasive brush also can reach the amount of grinding of regulation really.Like this, by for to make the load current value of motor reach predefined prescribed limit, the increase and decrease abrasive brush is to the approach of becket, thus can be not by the state of wear of abrasive brush about and the amount of grinding that obtains stipulating.

And, in the present invention, described the 1st brush grinding step and described the 2nd brush grinding step respectively brush grinding step before, be provided with following operation: the operation that the 1st current value that drives the described motor of this abrasive brush in rotating under the non-butt state of described abrasive brush and described becket is measured; To being connected to described becket at described abrasive brush and grinding amount of grinding in the ora terminalis of this becket and operation that the 2nd current value of described motor is measured; The increase part of the 2nd current value that will be for the 1st current value is as load current value, and calculates the operation of the dependency relation of this load current value and amount of grinding; According to the dependency relation of this load current value that calculates and amount of grinding, set the operation of the load current value of respectively brushing the prescribed limit in the grinding step.

The load current value of described motor can partly come according to the increase of the 2nd current value for described the 1st current value easily to try to achieve.In addition, according to the dependency relation of load current value and amount of grinding, the load current value in the time of can easily trying to achieve the amount of grinding that obtains stipulating.By in the described scope of setting the load current value so try to achieve before respectively brushing grinding step, then respectively brush in the grinding step described, can correctly carry out the increase and decrease of the abrasive brush corresponding to the approach of becket with load current value.

Like this,, the 1st rotating disk 81 and the 2nd rotating disk 82 are set, can append a plurality of table tops such as cleaning table top I1, I2 are set, thereby can carry out the grinding of more high-precision becket W by on the lapping device 80 of the 2nd embodiment.

Below, according to Figure 16, the 3rd embodiment of the present invention is described.In addition, about the part that in the 1st embodiment, has illustrated, because of in Figure 16, giving identical symbol, its explanation of Therefore, omited.The lapping device 83 of the 3rd embodiment does not use described rotating disk 2, and as shown in figure 16,7 table top B～H are configured to slightly linearity.At the 1st rough lapping table top B, be provided with the 1st rough lapping mechanism 7, in the middle of the 1st, grind table top C, be provided with the 1st middle grinding mechanism 8, at the 1st smooth grinding table top D, be provided with the 1st smooth grinding mechanism 9.In addition, at upset table top E, be provided with switching mechanism 10.In addition,, be provided with the 2nd rough lapping mechanism 11, in the middle of the 2nd, grind table top G, be provided with the 2nd middle grinding mechanism 12,, be provided with the 2nd smooth grinding mechanism 13 at the 2nd smooth grinding table top H at the 2nd rough lapping table top F.And, at each table top B～H, be respectively equipped with maintenance platform 4 identical and maintaining body 28 (with reference to Fig. 5 and Fig. 6) with the formation shown in the 1st embodiment.

In addition, between each keeps platform 4, be provided with the transfer mechanism 84 on from transfer on the side's that adjoins each other the maintenance platform 4 to the opposing party's maintenance platform 4 with becket W.At the upstream side of the 1st rough lapping table top B, be provided with and put into conveyer 14, putting between conveyer 14 and the 1st rough lapping table top B, be provided with and put into mechanism 5.In addition,, be provided with and send conveyer 72, at the 2nd smooth grinding table top H with send between the conveyer 72, be provided with delivering mechanism 6 in the downstream of the 2nd smooth grinding table top H.Each transfer mechanism 84 has the formation same with described delivering mechanism 6.

In the lapping device 83 of the 3rd embodiment, because each table top B～H is configured to slightly linearity, so can not need to put into/send table top A in the rotating disk 2 of lapping device 1 of the 1st embodiment.In addition, because by described transfer mechanism 84 with becket W when a side maintenance platform 4 transfers are to another maintenance platform 4, becket W is removed by the maintenance platform 4 from a side, therefore, by on each transfer mechanism 84, being provided with washer jet 85, can easily insert the maintenance platform 4 of having removed becket W or washing and cleaning operation that the becket W after grinding carries out.

Below, according to Figure 17, the 4th embodiment of the present invention is described.In addition, about the part that in the 1st embodiment, has illustrated, because of in Figure 17, giving identical symbol, its explanation of Therefore, omited.The lapping device 86 of the 4th embodiment substitutes described rotating disks 2 and the handover conveyer 87 of non junction shape is set, and its action is identical with described rotating disk 2.That is, transfer conveyer 87 along elliptical orbit roughly and in accordance with regulations distance intermittently transfer a plurality of maintenance platforms 4 at interval.In the 4th embodiment, each table top F, the G, the H that carry out each table top B, C, the D of the 1st brush grinding step and carry out the 2nd brush grinding step arrange with paralleling, and the round position between the 1st smooth grinding table top D and the 2nd rough lapping table top F is provided with the table top E that overturns.In view of the above, then do not need each transfer mechanism 84 in the lapping device 83 of aforesaid the 3rd embodiment, thereby can oversimplify so that device constitutes.In addition, on the lapping device 86 of the 4th embodiment, as shown in figure 17, between the 2nd smooth grinding table top H and the 1st rough lapping table top B, transfer the maintenance platform 4 that does not maintain becket W.At this moment, though not shown, also can clean maintenance platform 4.

In addition, in the respective embodiments described above, though exemplified the 1st brush grinding mechanism by grinding mechanism 8 in the middle of the 1st rough lapping mechanism the 7, the 1st, and the 1st smooth grinding mechanism 9 constitute, the 2nd brush grinding mechanism by grinding mechanism 12 in the middle of the 2nd rough lapping mechanism the 11, the 2nd, and the 2nd smooth grinding mechanism 13 constitute, but, be not limited in this, also can be for example, constitute the 1st brush grinding mechanism by the 1st rough lapping mechanism 7 and the 1st smooth grinding mechanism 9, constitute the 2nd brush grinding mechanism by the 2nd rough lapping mechanism 11 and the 2nd smooth grinding mechanism 13.

In addition, as the front according to Figure 10 illustrated, abrasive brush 60 crosses and each becket W of butt, by the rotation of this abrasive brush 60 and the rotation of becket W, can carry out the grinding of side edge on complete cycle of becket W.At this moment, preferably make incidence angle and the receding angle of abrasive brush 60 for becket W be all 20 ° to 45 °, in aforesaid each embodiment, as shown in figure 18, correctly set incidence angle θ and receding angle θ and be approximately 36 °.

At this,, illustrate that abrasive brush 60 does not reach 20 ° and the situation that surpasses 45 ° with respect to the incidence angle θ of becket W and receding angle θ with reference to Figure 19 (a) and Figure 19 (b).Shown in Figure 19 (a), when abrasive brush 60 did not reach 20 ° with respect to the incidence angle θ of becket W and receding angle θ, becket W was by abrasive brush 60 whole institute butts, caused the grinding of ora terminalis of becket W abundant inadequately.And because becket W enters among the abrasive brush 60, abrasive brush 60 is the inboard of butt becket W and the side face in the outside again, so, might abrade the problem of the side face in the inboard of becket W and the outside.And, for fear of this situation, in Figure 19 (a), shown in imaginary line, must use the less abrasive brush 60s of external diameter., the less abrasive brush 60s amount of bow of external diameter becomes again greatly, might cause grinding inadequately problem fully again.

On the other hand, shown in Figure 19 (b), when abrasive brush 60 surpasses 45 ° with respect to the incidence angle θ of becket W and receding angle θ, lacking extremely time on the abrasive brush 60 butt becket W, so still can cause grinding abundant inadequately.According to this reason, preferably making incidence angle θ and the receding angle θ of abrasive brush 60 for becket W is 20 ° to 45 °, in aforesaid each embodiment, approximately is set at 36 °.

In addition, in aforesaid each embodiment, in order to carry out the grinding of becket W expeditiously, and in advance the shape of the ora terminalis of the becket W before grinding is carried out chamfering.That is, in each embodiment, as shown in figure 20, adopted shearing device 88,, can make the cut-out ora terminalis of becket W be chamfer shape with when cutting out becket W by metallic cylinder X.This shearing device 88 is shown in Figure 20 as medelling, has: maintaining part material 89, and it is cylindric that this holding member 89 keeps metallic cylinder X; Discoid cutter 90, the sword face of this cutter 90 is peak shape; Cutter maintaining part 91, this cutter maintaining part 91 keeps cutter 90 to rotate freely; And accept roller 92, this accepts the outer peripheral face of roller 92 butt metallic cylinder X, and follows the rotation of metallic cylinder X and rotate.Accepting roller 92 is that rubber-like is plastic, when utilizing cutter 90 when metallic cylinder X is cut in interior all thrusters, then pushes metallic cylinder X from outer circumferential side.

And, as Figure 20 and shown in Figure 21, utilize cutter 90, cut out becket W by metallic cylinder X.Particularly, as shown in figure 20, Yi Bian the metallic cylinder X that is installed on the maintaining part material 89 is rotated, Yi Bian cutter 90 is pressed on the inner peripheral surface of metallic cylinder X by cutter maintaining part 91.At this moment, as shown in figure 21, the outer peripheral face of the metallic cylinder X that is pushed by cutter 90 is held by accepting roller 92.Because to accept roller 92 is that rubber-like is plastic, therefore,, the metallic cylinder X that is come up by cutter 90 pushings accepts roller 92 1 sides on one side bending towards, cut Yi Bian pushed away by cutter 90.In view of the above, as shown in figure 21, can obtain cutting off ora terminalis chamfering the becket W of shape.In addition, in the present embodiment, though exemplified from inner peripheral surface one thruster of metallic cylinder X and pressed cutter 90, but, in addition, though not shown, even keep metallic cylinder X in inner peripheral surface one side, and press cutter from outer peripheral face one thruster of metallic cylinder X, cut off becket W, also can form chamfering the cut-out ora terminalis.

In addition, in aforesaid each embodiment, as shown in figure 22, can keep between each maintaining body 28, setting the 1st finishing portion 93 on the platform 4.The 1st finishing portion 93 is along the track of abrasive brush 60 and be equipped with a plurality ofly, and the emery wheel of abrasive brush 60 front ends by being connected to rotation forms.

In addition, can the 2nd finishing portion 94 be set at the upper surface of each abutting part material 42 of each maintaining body 28.The 2nd finishing portion 94 forms by the upper surface that emery wheel is adhered to each abutting part material 42.Because maintaining body 28 rotates, also rotate so be arranged on the 2nd finishing portion 94 of the upper surface of each abutting part material 42.In view of the above, as shown in the figure, even the 2nd finishing portion 94 slenderly is arranged near the inboard of becket W of each abutting part material 42, the 2nd finishing portion 94 of rotation also is bound to cross the track of abrasive brush 60 and butt abrasive brush 60.

As Figure 22 and shown in Figure 23, the abrasive brush 60 of rotation is contacted with the 1st finishing portion 93 that is arranged on its track, in the uneven occasion of hair front end of abrasive brush 60, can cut by the 1st finishing portion 93 and shave to repair out a mao front end.

In addition, as Figure 22 and shown in Figure 23, the abrasive brush 60 of rotation is contacted with the 2nd finishing portion 94 on each the abutting part material 42 that is arranged on the maintaining body 28 that keeps becket W and rotate.The 2nd finishing portion 94 by with each abutting part material 42 be integral ground and with becket W co-rotation, cross the track and the butt abrasive brush 60 of abrasive brush 60.At this moment, owing to the 2nd finishing portion 94 rotates with respect to abrasive brush 60 and carries out butt, therefore, the friction that the 2nd finishing portion 94 and abrasive brush are 60 is bigger, thereby in a little time when passing through on the maintaining body 28, just can repair the hair front end of abrasive brush 60 really with high efficiency in the 2nd finishing portion 94.

Like this, because by the 1st finishing portion 93 or the 2nd finishing portion 94 are set, carry out the grinding of 60 couples of becket W of abrasive brush on one side, repair the dressing operation of the hair front end of abrasive brush 60 on one side simultaneously, so, not only can alleviate the maintenance operation of dressing operation after unloading of abrasive brush 60 got and replacing etc., but also can make the hair front end of abrasive brush 60 concordant, come butt becket W equably, thereby can improve grinding precision.

In addition, even much less any one party in the 1st finishing portion 93 and the 2nd finishing portion 94 certainly only is set, also can repair the hair front end of abrasive brush 60 fully.

In addition, if the 1st rough lapping mechanism 7 with the 1st embodiment described in Fig. 9 is that example describes, shown in Figure 9 as medelling, then this grinding mechanism 7 is provided with: load current value testing agency 95, this load current value testing agency 95 is used to detect the load current value of motor 59; And lifting control mechanism 96, this lifting control mechanism 96 is corresponding to controlling described elevating mechanism by these load current value testing agency 95 detected current values.Below, the action of load current value testing agency 95 and lifting control mechanism 96 is described.

In the grinding of becket W, as previously mentioned, on keeping each maintaining body 28 of platform 4,6 becket W have been installed after, rotate each maintaining body 28, in view of the above, each becket W is rotated.At this moment, by the driving of motor 59 (with reference to Fig. 9), brush 56 is rotated, and grinding mechanism 7 is descended, when abrasive brush 60 reaches the approach of regulation with respect to becket W, grinding mechanism 7 is fixed.In view of the above, as shown in figure 24, abrasive brush 60 is connected to the side edge of becket W, and abrasive brush 60 ground the side edge of becket W, thereby the side edge of becket W is ground.

Yet in case abrasive metal ring W, because the wearing and tearing of abrasive brush 60, the load current value of motor 59 changes.Because the variation of this load current value is detected by described load current value testing agency 95, so, for making detected load current value reach the load current value of predefined prescribed limit, and by described lifting control mechanism 96, and brush 56 is descended by means of elevating mechanism, in view of the above, approach is controlled to be necessarily.In addition, in Fig. 9, be that the support plate of the leading section of supporting abrasive brush 60 by making the abrasive brush 60 that is projected into the below from support plate 56a reach the overhang of regulation, and is paid appropriate rigidity and operating force to abrasive brush 60 shown in the symbol 56a.And when abrasive metal ring W, corresponding to the wearing and tearing of abrasive brush 60, the brush 56 that descends is so that the overhang of abrasive brush 60 reaches certain.So, can be so that the approach of 60 couples of becket W of abrasive brush reaches certain.

At this, further describe the action of described load current value testing agency 95 and described lifting control mechanism 96.Described load current value testing agency 95 calculates poor with between the current value (the 2nd current value) of (during grinding) mensuration when abrasive brush 60 and becket W are contact condition of (during idle running) is measured when abrasive brush 60 and becket W are contactless state current value (the 1st current value), detects load current value.

On the other hand, according to load current value that precomputes and the dependency relation between amount of grinding, and the range storage of load current value that will be corresponding with good amount of grinding is in described lifting control mechanism 96.Dependency relation between load current value and amount of grinding can followingly be tried to achieve.That is, in abrasive brush 60 rotated, when the side edge of butt becket W ground, 60 pairs of motors 59 of abrasive brush imposed load.The load that motor 59 is born is detected by described load current value testing agency 95 as the load current value of motor 59.At this moment, as shown in figure 25, when the approach L of 60 couples of becket W of abrasive brush was big, the load current value I of motor 59 was also bigger, and approach L hour, and load current value I is also less.

In addition, Figure 26 (a) represents the shape of the side edge of (attrition process is preceding) becket W after metallic cylinder cylindraceous is cut off just, shown in Figure 26 (b), when grinding if make that the approach L of 60 couples of becket W of abrasive brush is less, amount of grinding diminishes, and it is bigger curved shape that the side edge of becket W then is ground into its front-end radius.Shown in Figure 26 (c), when grinding if make that the approach L of 60 couples of becket W of abrasive brush is big, it is big to grind quantitative change, and it is less curved shape that the side edge of becket W then is ground into its front-end radius.Thus, can obtain in order to grind to form the necessary approach L of good curved shape.And, according to the relation between approach L shown in Figure 25 and load current value I, can obtain the range L of the approach L that reaches good ₁～L ₂The time the scope I of load current value I ₁～I ₂

96 pairs of described lifting control mechanisms by described load current value testing agency 95 detected load current values whether at prescribed limit I ₁～I ₂(corresponding to the scope of the load current value of good amount of grinding) monitor, when load current value than range limit I ₂When big, brush 56 is risen, also is, makes approach L Minus few, when load current value than scope lower limit I ₂Hour, brush 56 is descended, also be, approach L is increased.

In view of the above, particularly,, cause approach L to diminish, but, increase approach L, can keep good amount of grinding by brush 56 is descended even abrasive brush 60 weares and teares.That is, because in a single day abrasive brush 60 weares and teares, shown in Figure 26 (b), approach L diminishes, so abrasive brush 60 reduces at the load current value of motor 59.The load current value of this moment is detected by described load current value testing agency 95, and is sent to described lifting control mechanism 96.Because lifting control mechanism 96 makes brush 56 descend corresponding to the reduction of load current value, so approach L increases, and as shown in figure 24, can obtain good amount of grinding.

In addition, in described lifting control mechanism 96, be set with the falling-threshold position of brush 56.And, corresponding to by described load current value testing agency 95 detected load current values, and when increasing approach L, when the occasion that extremely wearing and tearing take place at abrasive brush 60 etc. and when surpassing the falling-threshold position of brush 56, can easily judge: undue wear has taken place in abrasive brush 60, cause the grainding capacity of abrasive brush 60 to produce reduction extremely, arrived replacing period.
