Description

本発明は、円板状のワークの両側面からそれぞれ軸方向に張出形成されたバリを除去するバリ取り装置に関する。   The present invention relates to a deburring device that removes burrs formed in an axial direction from both side surfaces of a disk-shaped workpiece.

（第１の従来技術）
例えば、ブレージングカッタにより歯車の歯先に面取りを施すと、歯車の側面縁にはバリが張出形成される。このようなバリの存在は好ましいものではなく、直ぐに取り除くことが望ましく、従来より種々のバリ取り装置が提案されている。 (First prior art)
For example, when chamfering is applied to the tooth tip of a gear with a brazing cutter, burrs are formed over the side edge of the gear. The presence of such burrs is not desirable, and it is desirable to remove them immediately, and various deburring devices have been proposed.

図６に示す従来のバリ取り装置１００は、センタチャックＢ１、Ｂ２により軸心回りに回転自在に支持され、ブレージングカッタＫにより回転される歯車Ｗに対して、軸心に直交する方向に接近及び離間するスライドテーブル１０１が設けられ、そのスライドテーブル１０１の上面に歯車Ｗの軸心Ｃに沿って平行に延在し、その両端がベアリングなどの回転支持部材１０２によって回転自在に支持された回転軸１０３と、その回転軸１０３に一体となって回転可能に外嵌されて軸方向に移動自在に支持された円盤状の丸バイト１１０が設けられている。   The conventional deburring device 100 shown in FIG. 6 is supported by the center chucks B1 and B2 so as to be rotatable around the axis, and approaches the gear W rotated by the brazing cutter K in a direction perpendicular to the axis. A rotating table having a slide table 101 that is spaced apart, extends in parallel along the axis C of the gear W on the upper surface of the slide table 101, and both ends of which are rotatably supported by a rotation support member 102 such as a bearing. 103 and a disc-shaped round tool 110 that is rotatably fitted integrally with the rotary shaft 103 and supported so as to be movable in the axial direction.

丸バイト１１０は、歯車Ｗの一方側面に対向する対向面１１１ａを有した第１円盤部１１１と、歯車Ｗの他方側面に対向する対向面１１２ａを有した第２円盤部１１２を有しており、この第１円盤部１１１と第２円盤部１１２には、対向面１１１ａ、１１２ａの外周端縁の一部を面取りすることによってワーク挿入部１１１ｂ、１１２ｂが形成されている。   The round tool 110 has a first disk portion 111 having a facing surface 111a facing one side surface of the gear W, and a second disk portion 112 having a facing surface 112a facing the other side surface of the gear W. In the first disk portion 111 and the second disk portion 112, work insertion portions 111b and 112b are formed by chamfering part of the outer peripheral edge of the opposing surfaces 111a and 112a.

そして、回転軸１０３に固定された第１バネ受部１０４と第１円盤部１１１との間には第１円盤部１１１を第２円盤部１１２側に向かって付勢する第１付勢手段１０５が介在され、回転軸１０３に固定された第２バネ受部１０６と第２円盤部１１２との間には第２円盤部１１２を第１円盤部１１１側に向かって付勢する第２付勢手段１０７が介在されている。それから、第１円盤部１１１の外周面に凹設された係合穴１１１ｃに位置決めピン１０８ａを係合させることによってワーク挿入部１１１ｂ、１１２ｂを歯車Ｗに対向する位置に配置できるように第１円盤部１１１と第２円盤部１１２の回転停止位置を位置決めする位置決めシリンダ１０８を有している。   And between the 1st spring receiving part 104 fixed to the rotating shaft 103, and the 1st disk part 111, the 1st urging means 105 which urges | biases the 1st disk part 111 toward the 2nd disk part 112 side. Is interposed between the second spring receiving portion 106 and the second disc portion 112 fixed to the rotation shaft 103, and the second energizing portion urges the second disc portion 112 toward the first disc portion 111 side. Means 107 are interposed. Then, the first disc is arranged so that the workpiece insertion portions 111b and 112b can be arranged at positions facing the gear W by engaging the positioning pins 108a with the engaging holes 111c provided in the outer peripheral surface of the first disc portion 111. A positioning cylinder 108 for positioning the rotation stop positions of the part 111 and the second disk part 112 is provided.

上記構成を有する従来のバリ取り装置１００によれば、位置決めシリンダ１０８によりワーク挿入部１１１ｂ、１１２ｂを所定の回転停止位置に位置決めした状態で、スライドテーブル１０１を歯車Ｗに接近する方向に移動させて、ワーク挿入部１１１ｂ、１１２ｂから第１円盤部１１１と第２円盤部１１２の間に歯車Ｗを挿入し、歯車Ｗの一方側面を第１円盤部１１１の対向面１１１ａで押圧し、歯車の他方側面を第２円盤部１１２の対向面１１２ａで押圧した状態としてから、位置決めシリンダ１０８による係合穴１１１ｃへの係合を解除する。   According to the conventional deburring device 100 having the above-described configuration, the slide table 101 is moved in the direction approaching the gear W while the workpiece insertion portions 111b and 112b are positioned at the predetermined rotation stop positions by the positioning cylinder 108. The gear W is inserted between the first disc portion 111 and the second disc portion 112 from the workpiece insertion portions 111b and 112b, one side surface of the gear W is pressed by the facing surface 111a of the first disc portion 111, and the other side of the gear is After the side surface is pressed by the opposing surface 112a of the second disk portion 112, the engagement of the positioning cylinder 108 with the engagement hole 111c is released.

それから、ブレージングカッタＫの回転駆動により歯車Ｗを回転させながらその歯先に面取り加工を施す。これにより、丸バイト１１０を歯車Ｗの回転に応じて共回りさせ、各対向面１１１ａ、１１２ａのエッジによって歯車Ｗの両側面に張出形成されたバリを各々そぎ落として除去する。   Then, the tooth tip is chamfered while the gear W is rotated by the rotational drive of the brazing cutter K. Thereby, the round bite 110 is rotated in accordance with the rotation of the gear W, and burrs formed on both side surfaces of the gear W by the edges of the opposing surfaces 111a and 112a are scraped off and removed.

そして、ブレージングカッタＫの回転駆動を開始してから予め設定された時間が経過した後、位置決めシリンダ１０８により位置決めピン１０８ａを突出させて第１円盤部１１１の外周面に押圧させた状態とし、第１円盤部１１１の回転により係合穴１１１ｃに係合させてワーク挿入部１１１ｂ、１１２ｂを歯車Ｗに対向する位置に配置してからスライドテーブル１０１を歯車Ｗから離間する方向に移動させて、第１円盤部１１１と第２円盤部１１２の間から歯車Ｗを抜き出す。   Then, after a predetermined time has elapsed since the rotational driving of the brazing cutter K is started, the positioning pin 108a is protruded by the positioning cylinder 108 and pressed against the outer peripheral surface of the first disk portion 111, and the first The first disk portion 111 is engaged with the engagement hole 111c by the rotation of the disc portion 111 and the workpiece insertion portions 111b and 112b are arranged at positions facing the gear W, and then the slide table 101 is moved away from the gear W, The gear W is extracted from between the first disk part 111 and the second disk part 112.

（第２の従来技術）
回転手段により例えば歯車等の円筒状のワークを軸心回りに回転させ、その回転するワークの側面縁に切削刃を所定の押圧力で圧接させて、側面縁のバリ取りを行うバリ取り装置が提案されている（例えば特許文献１を参照）。 (Second prior art)
A deburring device that deburrs a side edge by rotating a cylindrical workpiece such as a gear around an axis by a rotating means and pressing a cutting blade against the side edge of the rotating workpiece with a predetermined pressing force. It has been proposed (see, for example, Patent Document 1).

（第３の従来技術）
円板状のワークの両側面から軸方向に張出形成されたバリを除去するバリ取り装置として、ローラの外周面に周方向に連続してワークの端部が押し込まれる溝を凹設し、ワークを回転させてローラの溝にワークの端部を順次押し込むことにより溝の開口端縁でバリをそぎ落とすバリ取り装置が提案されている（例えば、特許文献２を参照）。 (Third prior art)
As a deburring device that removes burrs formed in the axial direction from both side surfaces of a disk-shaped workpiece, a groove into which the end of the workpiece is continuously pushed in the circumferential direction is recessed in the outer circumferential surface of the roller, There has been proposed a deburring device that removes burrs at the opening edge of the groove by rotating the work and sequentially pushing the end of the work into the groove of the roller (see, for example, Patent Document 2).

そして更に、そのローラの溝に、所定の外径を有するフローティングリングを遊嵌保持させ、ワークの端部の押し込みによりフローティングリングを押し移動させて、フローティングリングの一部を押し込み位置と軸心を間に介して反対方向に突出させた状態でワークを回転させることにより、バリをそぎ落とすと共にローラの溝内にそぎ落とされたバリをフローティングリングによって溝の外に掻き出す機構を有したバリ取り装置が提案されている（例えば、特許文献３を参照）。   Further, a floating ring having a predetermined outer diameter is loosely fitted and held in the groove of the roller, and the floating ring is pushed and moved by pushing the end of the workpiece, so that a part of the floating ring is pushed in and the axial center. A deburring device with a mechanism that scrapes off the burrs in the roller grooves by scraping them out of the grooves with a floating ring by rotating the work in the state of protruding in the opposite direction through Has been proposed (see, for example, Patent Document 3).

しかしながら、第１の従来技術の場合、対向面１１１ａ、１１２ａの外周端縁の一部にワーク挿入部１１１ｂ、１１２ｂが形成されているので、位置決めピン１０８ａを第１円盤部１１１に押し当てて回転停止位置を位置決めする際に、ワーク挿入部１１１ｂ、１１２ｂが歯車Ｗに押圧される位置に移動してきたところで、対向面１１１ａ、１１２ａの歯車Ｗへの押圧力が急激に減少して、歯車Ｗと丸バイト１１０との間に滑りが生じ、回転停止の位置決めができずに、動作サイクルが停止するおそれがあり、また、歯車Ｗと丸バイト１１０との滑りを防止すべく、第１付勢手段１０５と第２付勢手段１０７の付勢力を増大させると、バリだけでなく歯車Ｗの外周面まで削ってしまうおそれがある。また、バリ落とし作業後に、位置決めシリンダ１０８によりワーク挿入部１１１ｂ、１１２ｂを所定の回転停止位置に位置決めする工程が必要となり、当該工程によりサイクルタイムが長いという問題を有していた。   However, in the case of the first prior art, since the workpiece insertion portions 111b and 112b are formed on a part of the outer peripheral edge of the opposing surfaces 111a and 112a, the positioning pin 108a is pressed against the first disc portion 111 and rotated. When the workpiece insertion portions 111b and 112b are moved to positions where the gear W is pressed when the stop position is positioned, the pressing force of the opposing surfaces 111a and 112a to the gear W is drastically reduced. The first biasing means may prevent slippage between the gear W and the round bit 110 because slippage may occur between the round bite 110 and the rotation stop may not be performed and the operation cycle may stop. If the urging force of 105 and the second urging means 107 is increased, there is a risk that not only the burr but also the outer peripheral surface of the gear W will be scraped. In addition, after the deburring operation, a step of positioning the workpiece insertion portions 111b and 112b at a predetermined rotation stop position by the positioning cylinder 108 is required, and this process has a problem that the cycle time is long.

更に、第１円盤部１１１と第２円盤部１１２は、第１付勢手段１０５と第２付勢手段１０７という互いに独立した２つの付勢手段によって付勢されているので、互いに均一な押圧力で押圧することが困難であり、特に、歯車Ｗの側面の位置が軸方向に偏位した場合には、歯車Ｗの一方側面への押圧力が増大し、他方側面への押圧力が減少し、両側面間でバリ取り加工精度に差が生ずるおそれがある。また、歯車Ｗへの押圧力を調整する場合には、回転軸１０３をスライドテーブル１０１から取り外して全体を分解する必要がある。したがって、切削量（バリの取れ具合）を調整することが困難であり、調整作業に時間がかかるという問題を有している。   Further, since the first disk portion 111 and the second disk portion 112 are urged by two mutually independent urging means, that is, the first urging means 105 and the second urging means 107, a uniform pressing force can be obtained. In particular, when the position of the side surface of the gear W is displaced in the axial direction, the pressing force on one side surface of the gear W increases and the pressing force on the other side surface decreases. There may be a difference in deburring accuracy between both side surfaces. Further, when adjusting the pressing force to the gear W, it is necessary to remove the rotary shaft 103 from the slide table 101 and disassemble the whole. Therefore, it is difficult to adjust the cutting amount (deburring degree), and there is a problem that the adjustment work takes time.

また、第１円盤部１１１と第２円盤部１１２は、それぞれ中心に貫通形成された貫通孔に回転軸１０３を嵌挿することによって回転軸１０３と一体的に回転可能に支持されているが、各貫通孔の軸方向の長さは第１円盤部１１１の幅と第２円盤部１１２の幅の分だけであり、半径方向の距離に対して軸方向の長さが短いので、第１円盤部１１１と第２円盤部１１２の倒れにより軸方向の滑らかな動作を確保することが困難となるおそれがある。特に、歯車Ｗの第１円盤部１１１と第２円盤部１１２の間へのセットをワーク挿入部１１１ｂ、１１２ｂからの挿入により行っているので、倒れを生じやすく、また、歯車Ｗの両側面に挿入傷が付くおそれもある。   In addition, the first disk portion 111 and the second disk portion 112 are supported so as to be rotatable integrally with the rotation shaft 103 by inserting the rotation shaft 103 into through holes formed through the respective centers. The length of each through hole in the axial direction is only the width of the first disk portion 111 and the width of the second disk portion 112, and the length in the axial direction is shorter than the radial distance. There is a possibility that it is difficult to ensure a smooth operation in the axial direction due to the fall of the portion 111 and the second disk portion 112. In particular, since the setting of the gear W between the first disk portion 111 and the second disk portion 112 is performed by insertion from the workpiece insertion portions 111b and 112b, the gear W is liable to fall down, and the gear W is formed on both side surfaces. There is also a risk of insertion flaws.

第２の従来技術は、ワークの一方の側面縁をバリ取りするものであり、両方の側面縁のバリ取りを一度に行うことはできない。したがって、サイクルタイムが長く、製造数を増加させることは困難である。   The second prior art deburr one side edge of the workpiece, and cannot deburr both side edges at once. Therefore, the cycle time is long and it is difficult to increase the number of production.

第３の従来技術の場合は、両方の側面縁を一度にバリ取りすることはできるが、ワークの厚さが変化した場合には対応できず、汎用性がない。したがって、ワークの厚さごとに、対応する溝幅を有したローラを用意する必要があり、ローラ交換の段取りに時間を要し、使用していないローラの保管場所を確保する必要があるなどの問題を有している。   In the case of the third prior art, both side edges can be deburred at one time, but it cannot cope with a change in the thickness of the work and is not versatile. Therefore, it is necessary to prepare a roller with a corresponding groove width for each workpiece thickness, it takes time to set up rollers, and it is necessary to secure a storage place for unused rollers. Have a problem.

本発明は、これらの問題に鑑み、従来技術の課題を解決すべくなされたものであり、その目的は、種々の大きさを有するワークに対応し、短いサイクルタイムで安定したバリ取り加工精度を確保できるバリ取り装置を提供することにある。   In view of these problems, the present invention has been made to solve the problems of the prior art, and its purpose is to cope with workpieces having various sizes, and to provide stable deburring accuracy in a short cycle time.

フィードユニット３の移動制御により、第１大径部分１３と第２大径部分２３との間に歯車Ｗが介在されると、電磁弁５３の切換制御によりシリンダ機構４１のシリンダロッド４１ｂをシリンダ本体４１ａに退避する方向に移動させ、開閉ピン４２の先端部分を第１小径部分１４の第１対向面部１４ｂと第２小径部分２４の第２対向面部２４ｂとの間から抜脱する。   When the gear W is interposed between the first large diameter portion 13 and the second large diameter portion 23 by the movement control of the feed unit 3, the cylinder rod 41b of the cylinder mechanism 41 is moved to the cylinder body by the switching control of the electromagnetic valve 53. The tip end portion of the opening / closing pin 42 is removed from between the first facing surface portion 14b of the first small diameter portion 14 and the second facing surface portion 24b of the second small diameter portion 24.

開閉ピン４２が第１小径部分１４と第２小径部分２４との間から抜脱されると、付勢バネ３３の付勢力によって第１バリ取り部材１０の第１円盤部１１と第２バリ取り部材２０の第２円盤部２２とが互いに接近する方向に向かって移動する。これにより、歯車Ｗは、第１大径部分１３と第２大径部分２３との間で挟持され、歯車Ｗの両側面ｗ１、ｗ２には第１バリ取り面部１３ｃと第２バリ取り面部２３ｃが所定の押圧力で押圧される。   When the open / close pin 42 is removed from between the first small diameter portion 14 and the second small diameter portion 24, the first disc portion 11 and the second deburring of the first deburring member 10 are urged by the urging force of the urging spring 33. The second disk portion 22 of the member 20 moves in a direction approaching each other. Thus, the gear W is sandwiched between the first large-diameter portion 13 and the second large-diameter portion 23, and the first deburring surface portion 13c and the second deburring surface portion 23c are provided on both side surfaces w1 and w2 of the gear W. Is pressed with a predetermined pressing force.

ここで、第１バリ取り部材１０は、固定軸６に対して軸方向に移動自在に外嵌されているので、歯車Ｗの両側面ｗ１、ｗ２の位置に応じて軸方向に移動することができる。したがって、歯車Ｗの両側面ｗ１、ｗ２に対して第１バリ取り面部１３ｃ及び第２バリ取り面部２３ｃを互いに等しい押圧力で押圧することができる。   Here, since the first deburring member 10 is externally fitted to the fixed shaft 6 so as to be movable in the axial direction, the first deburring member 10 can be moved in the axial direction according to the positions of both side surfaces w1, w2 of the gear W. it can. Therefore, the first deburring surface portion 13c and the second deburring surface portion 23c can be pressed against the both side surfaces w1, w2 of the gear W with the same pressing force.

第１大径部分１３と第２大径部分２３で歯車Ｗを挟持すると、ブレージングカッタＫが図示していない回転駆動手段によって回転駆動され、歯車Ｗを回転させながら歯の両サイドに面取りを施す。そして、この面取り加工によって、歯車Ｗの両側面ｗ１、ｗ２には、その軸方向にバリが張出形成される。   When the gear W is sandwiched between the first large diameter portion 13 and the second large diameter portion 23, the brazing cutter K is rotationally driven by a rotational drive means (not shown), and the teeth W are chamfered while rotating the gear W. . And by this chamfering process, the burr | flash is formed in the both sides | surfaces w1 and w2 of the gearwheel W in the axial direction.

歯車ＷがブレージングカッタＫによって回転されると、第１バリ取り部材１０と第２バリ取り部材２０も歯車Ｗと連れ回りされる。したがって、歯車Ｗの両側面ｗ１、ｗ２が第１バリ取り面部１３ｃと第２バリ取り面部２３ｃに接面する範囲よりも回転方向手前側の箇所で歯車Ｗの両側面ｗ１、ｗ２に張出形成されているバリは、歯車Ｗに連れ回る第１バリ取り部材１０と第２バリ取り部材２０の第１バリ取り面部１３ｃと第２バリ取り面部２３ｃに接面する際に、第１バリ取り面部１３ｃのエッジ部分と第２バリ取り面部２３ｃのエッジ部分によって径方向外側から中心に向かってそぎ落とされて、除去される。   When the gear W is rotated by the brazing cutter K, the first deburring member 10 and the second deburring member 20 are also rotated with the gear W. Therefore, the both side surfaces w1, w2 of the gear W are formed to project on the both side surfaces w1, w2 of the gear W at a position in front of the rotation direction with respect to the range where the first deburring surface portion 13c and the second deburring surface portion 23c are in contact with each other. The first deburring surface portion of the first deburring surface portion 13c and the second deburring surface portion 23c of the first deburring member 10 and the second deburring member 20 that rotate along with the gear W is provided. The edge portion 13c and the edge portion of the second deburring surface portion 23c are scraped off from the radially outer side toward the center and removed.

ブレージングカッタＫの回転駆動を開始してから予め設定された時間が経過し、歯車Ｗの全周に亘って面取り加工とバリ取り加工が施されたと判断されると、ブレージングカッタＫの回転駆動を停止させると共に、電磁弁５３の切換制御を行い、シリンダ機構４１のシリンダ本体４１ａからシリンダロッド４１ｂを突出させて開閉ピン４２を第１小径部分１４と第２小径部分２４の間に挿入し、第１円盤部１２と第２円盤部２２を付勢バネ３３の付勢力に抗して互いに離間する方向に押し広げて移動させ、第１バリ取り面部１３ｃと第２バリ取り面部２３ｃとの離間距離ＸをＸ２とし、歯車Ｗの両側面ｗ１、ｗ２から第１バリ取り面部１３ｃと第２バリ取り面部２３ｃを離間させて所定の間隙を有して対向する位置に配置する。   If it is determined that chamfering processing and deburring processing have been performed over the entire circumference of the gear W after a predetermined time has elapsed since the rotational driving of the brazing cutter K is started, the rotational driving of the brazing cutter K is performed. In addition to stopping, switching control of the electromagnetic valve 53 is performed, the cylinder rod 41b is protruded from the cylinder body 41a of the cylinder mechanism 41, and the opening / closing pin 42 is inserted between the first small diameter portion 14 and the second small diameter portion 24, The 1 disc part 12 and the 2nd disc part 22 are pushed and moved in the direction away from each other against the urging force of the urging spring 33, and the separation distance between the first deburring surface part 13c and the second deburring surface part 23c is moved. X is X2, and the first deburring surface portion 13c and the second deburring surface portion 23c are separated from both side surfaces w1, w2 of the gear W, and are arranged at positions facing each other with a predetermined gap.

それから、フィードユニット３の移動制御により、可動台３ａが後退移動され、スライドテーブル４が待避位置に配置される。そして、センタチャックＢ１、Ｂ２から歯車Ｗが取り出される。以上の作業を、新しい歯車Ｗが搬入されるごとに繰り返し行う。   Then, by the movement control of the feed unit 3, the movable table 3 a is moved backward, and the slide table 4 is disposed at the retracted position. Then, the gear W is taken out from the center chucks B1 and B2. The above operation is repeated each time a new gear W is carried in.

上記構成を有するバリ取り装置１によれば、第１バリ取り面部１３ｃと第２バリ取り面部２３ｃとの離間距離Ｘを、歯車Ｗの両側面ｗ１、ｗ２の軸方向距離Ｙよりも狭い離間距離Ｘ１から歯車Ｗの両側面ｗ１、ｗ２に対して所定の間隙を有して対向する十分に広い離間距離Ｘ２にすることができる。   According to the deburring device 1 having the above-described configuration, the separation distance X between the first deburring surface portion 13c and the second deburring surface portion 23c is smaller than the axial distance Y between the side surfaces w1 and w2 of the gear W. A sufficiently large separation distance X2 that faces the both side surfaces w1, w2 of the gear W from X1 with a predetermined gap can be obtained.

したがって、歯車Ｗの両側面ｗ１、ｗ２を第１バリ取り面部１３ｃと第２バリ取り面部２３ｃから完全に離間させた状態で、歯車Ｗを第１円盤部１２と第２円盤部２２との間に配置し及び取り外すことができる。したがって、歯車Ｗの両側面ｗ１、ｗ２に第１円盤部１２、第２円盤部２２との接触によって挿入傷が付くのを防止でき、製品の品質低下を防ぐことができる。   Accordingly, the gear W is placed between the first disc portion 12 and the second disc portion 22 in a state where both side surfaces w1, w2 of the gear W are completely separated from the first deburring surface portion 13c and the second deburring surface portion 23c. Can be placed and removed. Therefore, it is possible to prevent the both side surfaces w1 and w2 of the gear W from being damaged due to contact with the first disk portion 12 and the second disk portion 22, and it is possible to prevent the quality of the product from deteriorating.

それから、開閉ピン４２を突出及び退避させるのみで第１バリ取り面部１３ｃと第２バリ取り面部２３ｃとの離間距離Ｘを歯車Ｗの両側面ｗ１、ｗ２の軸方向距離Ｙよりも拡大及び縮小することができるので、歯車Ｗを第１円盤部１２と第２円盤部２２との間に容易に介在させることができる。したがって、従来のように準備工程や段取り工程を設ける必要がなく、サイクルタイムの大幅な短縮を図ることができる。   Then, the distance X between the first deburring surface portion 13c and the second deburring surface portion 23c is enlarged and reduced more than the axial distance Y between the both side surfaces w1 and w2 of the gear W only by projecting and retracting the opening / closing pin 42. Therefore, the gear W can be easily interposed between the first disk portion 12 and the second disk portion 22. Therefore, it is not necessary to provide a preparation process or a setup process as in the prior art, and the cycle time can be greatly shortened.

そして、第１バリ取り部材１０の第１軸部１１は固定軸６に対して軸方向に移動自在に外嵌されており、第２バリ取り部材２０の第２軸部２１は第１バリ取り部材１０の第１軸部１１に対して軸方向に移動自在に外嵌されている。したがって、第１バリ取り部材１０と第２バリ取り部材２０は、歯車Ｗの位置に応じて軸方向に自由に移動することができる。   The first shaft portion 11 of the first deburring member 10 is externally fitted to the fixed shaft 6 so as to be movable in the axial direction, and the second shaft portion 21 of the second deburring member 20 is the first deburring member. The member 10 is externally fitted to the first shaft portion 11 of the member 10 so as to be movable in the axial direction. Therefore, the first deburring member 10 and the second deburring member 20 can freely move in the axial direction according to the position of the gear W.

これにより、歯車Ｗの両側面ｗ１、ｗ２に対して第１バリ取り面部１３ｃと第２バリ取り面部２３ｃを互いに等しい押圧力で押圧することができ、両側面ｗ１、ｗ２の間でバリ取り加工精度を等しくし、バリ取り加工精度が安定した歯車Ｗを供給することができる。そして更に、歯車Ｗの個々の製造誤差に影響を受けることなく、均一なバリ取り加工を施すことができ、種々の軸方向距離Ｙ及び直径を有する歯車Ｗに対応することができ、高い汎用性を有する。   Accordingly, the first deburring surface portion 13c and the second deburring surface portion 23c can be pressed against the both side surfaces w1, w2 of the gear W with the same pressing force, and the deburring process is performed between the both side surfaces w1, w2. It is possible to supply the gear W with equal accuracy and stable deburring accuracy. Furthermore, uniform deburring can be performed without being affected by individual manufacturing errors of the gear W, and the gear W having various axial distances Y and diameters can be applied. Have

また、第１軸部１１は、固定軸６に外嵌されてその軸方向に沿って所定長さに亘って延在する長さを有し、第２軸部２１は、第１軸部１１に外嵌されてその軸方向に沿って所定長さに亘って延在する長さを有しており、それぞれ半径方向の長さに対して軸方向の長さが十分に確保されている。したがって、開閉ピン４２を第１対向面部１４ｂと第２対向面部２４ｂの間に介在させることにより第１バリ取り部材１０と第２バリ取り部材２０を軸方向に移動させた際に、第１バリ取り部材１０と第２バリ取り部材２０の倒れやガタつきを防ぎ、軸方向の滑らかな移動を確保することができる。   The first shaft portion 11 has a length that is externally fitted to the fixed shaft 6 and extends over a predetermined length along the axial direction, and the second shaft portion 21 is the first shaft portion 11. And has a length extending over a predetermined length along the axial direction, and a sufficient axial length is ensured for each radial length. Therefore, when the first deburring member 10 and the second deburring member 20 are moved in the axial direction by interposing the opening / closing pin 42 between the first facing surface portion 14b and the second facing surface portion 24b, the first deburring member 20 is moved. It is possible to prevent the removal member 10 and the second deburring member 20 from falling over and rattling, and to ensure smooth movement in the axial direction.

特に、本実施の形態では、第１大径部分１３，第２大径部分２３よりも半径が小さく軸心に近い位置に設けられている第１小径部分１４と第２小径部分２４に開閉ピン４２を当接させているので、第１バリ取り部材１０と第２バリ取り部材２０をより滑らかに移動させることができる。   Particularly, in the present embodiment, the first small diameter portion 13 and the second small diameter portion 24 are provided with opening / closing pins on the first small diameter portion 14 and the second small diameter portion 24 that are provided in positions closer to the shaft center than the first large diameter portion 13 and the second large diameter portion 23. Since 42 is contact | abutted, the 1st deburring member 10 and the 2nd deburring member 20 can be moved more smoothly.

更に上記バリ取り装置１は、第２調整ナット３２を回転させることによって、第１バリ取り面部１３ｃと第２バリ取り面部２３ｃの歯車Ｗへの押圧力を調整することができる。したがって、切削量（バリの取れ具合）を容易に調整することができ、調整作業にかかる時間を短縮することができる。   Further, the deburring device 1 can adjust the pressing force of the first deburring surface portion 13c and the second deburring surface portion 23c to the gear W by rotating the second adjustment nut 32. Therefore, the cutting amount (deburring degree) can be easily adjusted, and the time required for the adjustment work can be shortened.

尚、本発明は、上述の実施の形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々の変更が可能である。例えば、上述の実施の形態では、バリ取り装置１によるバリ取り作業を制御部５０による自動制御によって行う場合を例に説明したが、作業者の操作によって個々に行ってもよい。   In addition, this invention is not limited to the above-mentioned embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the above-described embodiment, the case where the deburring operation by the deburring apparatus 1 is performed by automatic control by the control unit 50 has been described as an example, but may be performed individually by the operator's operation.
