Description

本発明は、歯切り等の加工が行われるワークをクランプする治具に関し、特に複数のリング状のワークを積み重ねた状態でクランプする治具に関する。   The present invention relates to a jig for clamping a work to be processed such as gear cutting, and more particularly to a jig for clamping a plurality of ring-shaped works in a stacked state.

平行に形成される二つの端面を有するリング状のワークを積み重ねた状態で歯形を成形する加工を行う装置のクランプ治具としては、図３に示す如きものがあった。図３に示されるのは、ホブカッタ１６１により歯切り加工を行う歯切り盤における、リング状のワークＷ１０１をクランプするためのクランプ治具１０１である。このクランプ治具１０１は、ワークＷ１０１の内径部１７３に挿入される芯金１５２と、下側からワークＷ１０１を支持する支持部１５４を有するベース１５１と、ワークＷ１０１の上側を押圧するクランプ部１１１を有するクランパー１０２とを備える。このクランプ治具１０１により、ワークＷ１０１は上方面１７１をクランプ部１１１で押圧され、下方面１７２を支持部１５４で支持された状態でクランプされ、ホブカッタ１６１により歯切り加工が行われる。   As a clamping jig of an apparatus for performing processing for forming a tooth profile in a state in which ring-shaped workpieces having two end surfaces formed in parallel are stacked, there is a clamp jig as shown in FIG. FIG. 3 shows a clamping jig 101 for clamping a ring-shaped workpiece W101 in a gear cutting machine that performs gear cutting with a hob cutter 161. The clamp jig 101 includes a metal core 152 inserted into the inner diameter portion 173 of the workpiece W101, a base 151 having a support portion 154 that supports the workpiece W101 from below, and a clamp portion 111 that presses the upper side of the workpiece W101. The clamper 102 is provided. The clamp jig 101 clamps the workpiece W101 with the upper surface 171 pressed by the clamp portion 111 and the lower surface 172 supported by the support portion 154, and gear cutting is performed by the hob cutter 161.

実開平３−４７７２２号Japanese Utility Model Publication 3-47722

上記の如きクランプ治具１０１でクランプされたワークＷ１０１には、製造上の誤差として許容範囲内の数値で、両端面の平行度に誤差が生じている場合がある。そのようなワークＷ１０１が複数重なると誤差が累積し、平行度の誤差が大きくなる。すると、クランパー１０２のクランプ部１１１はワークＷ１０１の状態に倣ってワークＷ１０１を押圧しようとするため、クランパー１０２は軸心が傾斜する。同時に、クランパー１０２から芯金１５２に大きい曲げ荷重がかかり、芯金１５２が湾曲してしまうことが考えられる。芯金１５２が湾曲するとワークＷ１０１のセンタリングが正しく行われない状態で歯切り加工が行われ、そのため、ホブカッタ１６１が均一な状態でワークＷ１０１に当接することができず、歯溝の振れが大きくなるという不具合が生じることが考えられる。   The workpiece W101 clamped by the clamping jig 101 as described above may have an error in the parallelism of both end surfaces with a numerical value within an allowable range as a manufacturing error. When a plurality of such workpieces W101 overlap, errors accumulate and parallelism errors increase. Then, the clamp portion 111 of the clamper 102 tries to press the workpiece W101 following the state of the workpiece W101, so that the axis of the clamper 102 is inclined. At the same time, it is conceivable that a large bending load is applied from the clamper 102 to the cored bar 152 and the cored bar 152 is bent. When the cored bar 152 is curved, gear cutting is performed in a state where the centering of the workpiece W101 is not performed correctly. Therefore, the hob cutter 161 cannot be brought into contact with the workpiece W101 in a uniform state, and the tooth gap is greatly shaken. It is conceivable that this problem will occur.

従って、本発明は上述の如き課題を解決し、ワークを複数積み重ねた状態で歯車加工を行ったときに、ワークの平行度の誤差が大きくても、歯溝の振れを低減できるクランプ治具を提供することを目的とする。   Therefore, the present invention solves the problems as described above, and when a gear is machined with a plurality of workpieces stacked, a clamping jig that can reduce tooth groove run-out even if the workpiece parallelism error is large. The purpose is to provide.

本発明のクランプ治具は、歯面に加工が行われるリング状のワークの内径部に挿入される軸状の芯金と、芯金に挿入されたワークの一方面を押圧するクランプ部を有するクランパーと、ワークの他方面を支持する支持部とを備え、複数のワークを積み重ねてクランプし、クランパーがワークに均一の荷重を付与して固定する油圧機構を備えることを特徴とする。   The clamp jig of the present invention has a shaft-shaped core metal inserted into an inner diameter portion of a ring-shaped workpiece to be processed on a tooth surface, and a clamp portion that presses one surface of the workpiece inserted into the core metal. A clamper and a support part that supports the other surface of the workpiece are provided, and a plurality of workpieces are stacked and clamped, and the clamper is provided with a hydraulic mechanism that applies a uniform load to the workpiece and fixes the workpiece.

本発明の特徴によるクランプ治具によれば、歯形加工が行われるリング状のワークの内径部に挿入される軸状の芯金と、芯金に挿入されたワークの一方面を押圧するクランプ部を有するクランパーと、ワークの他方面を支持する支持部とを備え、複数のワークを積み重ねてクランプし、クランプ部がワークに均一の荷重を付与して固定する油圧機構を備えるので、歯面加工時に積み重ねたワークの平行度の誤差が累積して大きな誤差を生じても、油圧機構が誤差を吸収するため、芯金にクランパーからの曲げ荷重がかからないので、芯金を曲げることなくセンタリングした状態で加工でき、歯溝の振れを低減することができる。   According to the clamp jig according to the feature of the present invention, a shaft-shaped metal core inserted into an inner diameter portion of a ring-shaped workpiece on which tooth profile processing is performed, and a clamp portion that presses one surface of the workpiece inserted into the metal core Since it has a hydraulic mechanism that stacks and clamps a plurality of workpieces and applies a uniform load to the workpiece, it is equipped with a clamper having a clamp and a support portion that supports the other surface of the workpiece. Even if errors in the parallelism of stacked workpieces sometimes accumulate and cause a large error, the hydraulic mechanism absorbs the error, so the bending load from the clamper is not applied to the cored bar, so that the cored bar is centered without bending Can reduce the runout of the tooth gap.

本発明の実施の形態を、添付図面に示す本発明の好適な実施例に基づいて以下に説明する。   Embodiments of the present invention will be described below on the basis of preferred embodiments of the present invention shown in the accompanying drawings.

FIG. 1 shows a clamp jig 1 used in a hobbing machine that performs gear cutting with a hob cutter 61 on a ring-shaped workpiece W1 having opposite end faces in parallel with both axial surfaces. The clamp jig 1 includes a base 51 and a clamper 2 disposed on the upper side so as to be coaxial with the base 51. The clamper 2 is coupled to a support portion 81 disposed above by a coupling bolt 82.

上記クランプ治具１について詳細に説明する。まずベース５１について詳細に説明する。ベース５１は、リング状のワークＷ１の内径部７３と略同径の外径を有する芯金部５７と、芯金部５７から連続し、芯金部５７より小径の外径を有する小径軸５３とよりなる芯金５２と、芯金５２の小径軸５３と反対側に連続し芯金部５７より大径の支持部５４とを有する。この支持部５４は芯金５２の軸心に対して直交する支持部端面５５を有し、支持部端面５５から連続して、切り粉を排出するための切り欠き５６が形成されている。   The clamp jig 1 will be described in detail. First, the base 51 will be described in detail. The base 51 has a cored bar 57 having an outer diameter substantially the same as the inner diameter part 73 of the ring-shaped workpiece W1, and a small-diameter shaft 53 that is continuous from the cored bar 57 and has a smaller outer diameter than the cored bar 57. And a support portion 54 that is continuous with the small-diameter shaft 53 of the core metal 52 on the side opposite to the small-diameter shaft 53 and has a larger diameter than the core metal portion 57. The support portion 54 has a support portion end face 55 orthogonal to the axis of the core metal 52, and a notch 56 for discharging chips is formed continuously from the support portion end face 55.

次にクランパー２について詳細に説明する。クランパー２は、内径側に小径軸５３を係合する第二クランパー２３と、第二クランパー２３と同心で第二クランパー２３の外周側に配置される第一クランパー３とより成る。まず第二クランパー２３について説明する。第二クランパー２３は、一方に一方開口２４、他方に他方開口２５を有し、内側には他方開口２５から連続し第二軸５３と同径の孔部である係合部２６と、係合部２６から連続し一方開口２４まで貫通する係合部２６より小径の孔部である小径孔部２７とを有する。また外周面は、一方開口２４側から第一円筒部２８と、第一円筒部２８から連続し第一円筒部２８より大径の外径を有する第二円筒部２９と、第二円筒部２９から連続し第二円筒部２９より小径の第三円筒部３０とよりなる。第二円筒部２９は周状の凹部である第二溝部３１と、内外周を連通するエア抜き溝３２が形成されている。   Next, the clamper 2 will be described in detail. The clamper 2 includes a second clamper 23 that engages the small-diameter shaft 53 on the inner diameter side, and a first clamper 3 that is concentric with the second clamper 23 and disposed on the outer peripheral side of the second clamper 23. First, the second clamper 23 will be described. The second clamper 23 has one opening 24 on one side and the other opening 25 on the other side, and is engaged with an engaging part 26 that is continuous from the other opening 25 and has the same diameter as the second shaft 53. And a small-diameter hole 27 that is a hole having a smaller diameter than the engaging portion 26 that continues from the portion 26 to the one opening 24. The outer peripheral surface includes a first cylindrical portion 28 from one opening 24 side, a second cylindrical portion 29 that is continuous from the first cylindrical portion 28 and has an outer diameter larger than that of the first cylindrical portion 28, and a second cylindrical portion 29. And a third cylindrical portion 30 having a smaller diameter than the second cylindrical portion 29. The second cylindrical portion 29 is formed with a second groove portion 31 that is a circumferential recess and an air vent groove 32 that communicates the inner and outer periphery.

第一クランパー３は、上側に小開口４、下側に小開口４より大径の大開口５を有し、内側には小開口４から連続する孔部である中孔部６と、中孔部６から連続し第二クランパー２３の第三円筒部３０と略同径の内径を有する小孔部７と、小孔部７から連続し小孔部７より大径で大開口５まで貫通する大孔部８とを有する。また外周面は、小開口４側から小円筒部９と、小円筒部９から連続し小円筒部９より大径の外径を有する大円筒部１０とよりなり、大円筒部１０の大開口５側にはワークＷ１を押圧するクランプ部１１が形成されている。また、小孔部７を形成する小孔部内周面１５には、周状の凹部である第一溝部１２が形成され、また小孔部７とは別に中孔部６と大孔部８とを繋ぐ極小孔部１３が形成され、極小孔部１３には小ボルト１４が螺合している。   The first clamper 3 has a small opening 4 on the upper side, a large opening 5 having a diameter larger than that of the small opening 4 on the lower side, and a medium hole 6 that is a hole continuous from the small opening 4 on the inner side, A small hole portion 7 that continues from the portion 6 and has an inner diameter substantially the same diameter as the third cylindrical portion 30 of the second clamper 23, and extends from the small hole portion 7 to the large opening 5 with a larger diameter than the small hole portion 7. And a large hole portion 8. The outer peripheral surface includes a small cylindrical portion 9 from the small opening 4 side, and a large cylindrical portion 10 that is continuous from the small cylindrical portion 9 and has an outer diameter larger than that of the small cylindrical portion 9. A clamp portion 11 that presses the workpiece W1 is formed on the 5 side. In addition, a first groove portion 12 which is a circumferential recess is formed on the small hole inner peripheral surface 15 forming the small hole portion 7, and in addition to the small hole portion 7, the middle hole portion 6 and the large hole portion 8 Are formed, and a small bolt 14 is screwed into the minimal hole portion 13.

第一クランパー３と第二クランパー２３の結合構造を説明する。第二クランパー２３の第二円筒部２９が第一クランパー３の中孔部６に、第二クランパー２３の第三円筒部３０が第一クランパー３の小孔部７にそれぞれ係合し、結合してクランパー２を構成している。また第二クランパー２３の第二溝部３１及び第一クランパー３の小孔部７にはオイルシールとして、弾性部材製のＯリング４１がそれぞれ装着されている。ここで第二クランパー２３の第二円筒部２９と第一クランパー３の大円筒部１０との間には空間が形成され、シリンダー室４２となっている。このシリンダー室４２には、極小孔部１３から油圧作動油が充填され、油圧機構となっている。また第二クランパー２３の第三円筒部３０は第一クランパー３の小孔部７から大孔部８へ突出しており、第三円筒部３０の外周には小孔部内周面１５の大開口５側端面に当接するようにＣリング４３が嵌合している。   A coupling structure of the first clamper 3 and the second clamper 23 will be described. The second cylindrical portion 29 of the second clamper 23 is engaged with the middle hole portion 6 of the first clamper 3, and the third cylindrical portion 30 of the second clamper 23 is engaged with the small hole portion 7 of the first clamper 3. The clamper 2 is configured. An O-ring 41 made of an elastic member is mounted as an oil seal in the second groove portion 31 of the second clamper 23 and the small hole portion 7 of the first clamper 3. Here, a space is formed between the second cylindrical portion 29 of the second clamper 23 and the large cylindrical portion 10 of the first clamper 3 to form a cylinder chamber 42. The cylinder chamber 42 is filled with hydraulic fluid from the micro hole 13 to form a hydraulic mechanism. The third cylindrical portion 30 of the second clamper 23 protrudes from the small hole portion 7 of the first clamper 3 to the large hole portion 8, and the large opening 5 of the small hole inner peripheral surface 15 is formed on the outer periphery of the third cylindrical portion 30. A C-ring 43 is fitted so as to contact the side end surface.

次に上記クランプ治具１を使用してワークＷ１をクランプする状態を説明する。まずワークＷ１がクランプされる前の状態では、クランパー２はベース５１の上方に、ベース５１から離間した状態に配置されている。そこでベース５１の芯金部５７にワークＷ１の内径部７３を貫通させ、支持部５４の上側に形成される支持部端面５５に下方面７２を当接させたリング状のワークＷ１を五つ積み重ねた状態に載置する。   Next, a state in which the workpiece W1 is clamped using the clamp jig 1 will be described. First, in a state before the workpiece W1 is clamped, the clamper 2 is disposed above the base 51 and separated from the base 51. Therefore, five ring-shaped workpieces W1 in which the inner diameter portion 73 of the workpiece W1 is passed through the core bar portion 57 of the base 51 and the lower surface 72 is in contact with the support portion end surface 55 formed on the upper side of the support portion 54 are stacked. Place it on the ground.

続いてクランパー２がベース５１方向に移動する。するとクランパー２の第二クランパー２３の係合部２６内にベース５１の小径軸５３が挿入され、やがて第一クランパー３のクランプ部１１がワークＷ１の上方面７１に当接する。このクランパー２のクランプ部１１とベース５１の支持部５４とで、上下方向からワークＷ１をクランプする。このとき、それぞれのワークＷ１は両端面の平行度が許容範囲内の誤差を有し、この誤差が累積してワークＷ１の平行度の誤差が大きくなっている。すると、図２に示す如く、クランパー２のクランプ部１１はワークＷ１の状態に倣ってワークＷ１を押圧するため、クランパー２の第一クランパー３は軸心が傾斜した状態となる。このように第一クランパー３は軸心が傾斜した状態になるが、クランパー２は油圧機構を有しているので、第一クランパー３はシリンダー室３２内で芯金５２に影響を与えずに傾斜し、パスカルの原理によりクランプ部１１はワークＷ１に対して均一の荷重を加えた状態で押圧する。   Subsequently, the clamper 2 moves toward the base 51. Then, the small-diameter shaft 53 of the base 51 is inserted into the engaging portion 26 of the second clamper 23 of the clamper 2, and eventually the clamp portion 11 of the first clamper 3 comes into contact with the upper surface 71 of the workpiece W1. The workpiece W1 is clamped in the vertical direction by the clamp portion 11 of the clamper 2 and the support portion 54 of the base 51. At this time, each workpiece W1 has an error in which the parallelism of both end faces is within an allowable range, and this error is accumulated to increase the parallelism error of the workpiece W1. Then, as shown in FIG. 2, the clamp portion 11 of the clamper 2 presses the workpiece W1 following the state of the workpiece W1, so that the first clamper 3 of the clamper 2 is in a state where the axis is inclined. Thus, although the first clamper 3 is in a state where the axis is inclined, the clamper 2 has a hydraulic mechanism, so the first clamper 3 is inclined without affecting the cored bar 52 in the cylinder chamber 32. However, the clamp portion 11 presses the workpiece W1 with a uniform load applied according to Pascal's principle.

上記の如き状態でクランプ治具１にクランプされたワークＷ１は図示せぬ回転機構により回転し、ホブカッタ６１で歯切り加工される。   The workpiece W1 clamped by the clamping jig 1 in the above-described state is rotated by a rotating mechanism (not shown) and is geared by the hob cutter 61.

よって、上記の如きクランプ治具１によれば、歯面に加工が行われるリング状のワークＷ１の内径部７３に挿入される軸状の芯金５２と、芯金５２に挿入されたワークＷ１の一方面７１を押圧するクランプ部１１を有するクランパー２と、ワークＷ１の他方面７２を支持する支持部５４とを備え、クランパー２がワークＷ１に均一の荷重を付与して固定する油圧機構を備えるので、ワークＷ１の平行度が許容範囲内の誤差を有し、この誤差が累積してワークＷ１の平行度の誤差が大きくなっていると、クランパー２のクランプ部１１はワークＷ１の状態に倣ってワークＷ１を押圧するが、クランパー２は油圧機構を有しているので、第一クランパー３はシリンダー室３２内で芯金５２に影響を与えずに傾斜し、パスカルの原理によりクランプ部１１はワークＷ１に対して均一の荷重を加えた状態で押圧する。そのためクランプ部１１から芯金５２に曲げ荷重が付与されないので、歯切り加工時にワークＷ１の平行度が誤差を生じていても、芯金５２が湾曲することはない。よって、ワークＷ１は芯金５２により正常にセンタリングされた状態で歯切り加工が施される。   Therefore, according to the clamp jig 1 as described above, the shaft-shaped cored bar 52 inserted into the inner diameter portion 73 of the ring-shaped workpiece W1 to be processed on the tooth surface, and the workpiece W1 inserted into the cored bar 52. A hydraulic mechanism that includes a clamper 2 having a clamp portion 11 that presses one side 71 of the workpiece and a support portion 54 that supports the other side 72 of the workpiece W1, and the clamper 2 applies a uniform load to the workpiece W1 and fixes the workpiece W1. Therefore, if the parallelism of the work W1 has an error within an allowable range, and this error is accumulated to increase the parallelism error of the work W1, the clamp portion 11 of the clamper 2 is in the state of the work W1. The workpiece W1 is pressed in a similar manner, but since the clamper 2 has a hydraulic mechanism, the first clamper 3 tilts in the cylinder chamber 32 without affecting the cored bar 52 and is clamped by the Pascal principle. 11 is pressed while applying a load of uniform for the work W1. Therefore, since no bending load is applied from the clamp portion 11 to the cored bar 52, the cored bar 52 will not bend even if the parallelism of the workpiece W1 has an error during gear cutting. Therefore, the workpiece W1 is subjected to gear cutting while being normally centered by the core metal 52.

なお、上記実施例においてはワークが五つ積み重ねられているが、ワークの個数は限定されることはない。   In the above embodiment, five workpieces are stacked, but the number of workpieces is not limited.

また、上記実施例においてはワークをセンタリングするための芯金がワークの下方に位置する支持部と一体に形成されているが、この形状に限定されるわけではなく、上方に配置されるサポートと一体に形成される等、種々の設計変更が可能である。   Moreover, in the said Example, although the metal core for centering a workpiece | work is integrally formed with the support part located in the downward direction of a workpiece | work, it is not necessarily limited to this shape, The support arrange | positioned upwards Various design changes such as being formed integrally are possible.
