しかしながら、整流子素材を切削して整流子素材から整流子を製造する際に、切削工具を整流子素材に対し軸方向一方側から他方側へ相対移動させるとき（往路移動時）のみ整流子素材の外周面を切削し、切削工具を整流子素材に対し軸方向他方側から一方側へ相対移動させるとき（復路移動時）を原点位置に復帰させるためのエアカットとすると、この切削工具を整流子素材に対し軸方向他方側から一方側へ相対移動させることが無駄となり、生産効率が低下する。   However, when the commutator material is cut to produce a commutator from the commutator material, the commutator material is only moved when the cutting tool is moved relative to the commutator material from one side to the other in the axial direction (during forward movement). When cutting the outer peripheral surface of the metal and cutting the tool relative to the commutator material from the other side in the axial direction from one side to the other (when moving in the return path), the cutting tool is rectified. It is useless to move relative to the child material from the other side in the axial direction to one side, and the production efficiency is lowered.

本発明は、上記課題に鑑みてなされたものであって、生産効率を向上させることができる整流子の製造方法及び製造装置を提供することを目的とする。   This invention is made | formed in view of the said subject, Comprising: It aims at providing the manufacturing method and manufacturing apparatus of a commutator which can improve production efficiency.

A first step of rough cutting the outer peripheral surface of the commutator material by using a rough cutting blade surface which is a first flank formed on a cutting bit of the cutting tool , relative to the other side of the cutting tool ; The cutting tool is moved relative to the commutator material in the circumferential direction of the commutator material while being relatively moved from the other axial side of the commutator material to the second side, and is formed on the cutting tool. A second step of finishing cutting the outer peripheral surface of the commutator material using a finishing cutting blade surface that is a flank surface of the rough cutting blade surface and the axial surface of the commutator material A first clearance angle θ1, which is an angle formed, and Characterized by using the cutting tool the relation between the second relief angle .theta.2 is an angle between the axial surface of the commutator materials and increased cutting edge surface satisfies .theta.1 ≧ .theta.2.

請求項１に記載の整流子の製造方法によれば、整流子素材を切削して整流子素材から整流子を製造する際に、切削工具を整流子素材に対し軸方向一方側から他方側へ相対移動させるとき（往路移動時）に加えて、切削工具を整流子素材に対し軸方向他方側から一方側へ相対移動させるとき（復路移動時）にも、整流子素材の外周面を切削工具により切削する。従って、切削工具を整流子素材に対し軸方向他方側から一方側へ相対移動させることが無駄となることを防止できるので、これにより、生産効率を向上させることができる。
特に、請求項１に記載の整流子の製造方法によれば、第一工程において整流子素材の外周面を切削工具により荒削り切削した後に、第二工程において整流子素材の外周面を切削工具により仕上げ切削するので、生産効率を向上させつつ、整流子の仕上がりの品質（例えば、真円度、各セグメント間の段差、外周面の表面粗さ、バリの完全除去等に関する品質）を確保できる。
しかも、請求項１に記載の整流子の製造方法によれば、整流子素材の外周面を荒削り切削するための荒削り切削用刃面と、整流子素材の外周面を仕上げ切削するための仕上げ切削用刃面と、を有する切削バイトを用いる。従って、荒削り切削加工（第一工程）と仕上げ切削加工（第二工程）とでそれぞれ専用の切削バイトを用いる必要が無い。このため、荒削り切削加工と仕上げ切削加工とで切削装置を別々としたり、荒削り切削加工と仕上げ切削加工とで各切削バイトを交換したり、荒削り切削加工及び仕上げ切削加工に合わせて切削工具を最適角度に傾斜させたりする必要が無い。これにより、生産効率をより一層向上させることができる。
また、請求項１に記載の整流子の製造方法によれば、荒削り切削用刃面と整流子素材の軸方向表面とのなす角度θ１と、仕上げ切削用刃面と整流子素材の軸方向表面とのなす角度θ２との関係がθ１≧θ２を満足する切削バイトを用いる。これにより、一つの切削バイトにより整流子素材の外周面の荒削り切削と仕上げ切削を行うことが可能となる。 According to the method for manufacturing a commutator according to claim 1, when the commutator material is cut to manufacture the commutator from the commutator material, the cutting tool is moved from one side to the other side in the axial direction with respect to the commutator material. In addition to the relative movement (during forward movement), the cutting tool can also be used to move the outer peripheral surface of the commutator material relative to the commutator material from the other side in the axial direction to one side (during backward movement). Cut by. Accordingly, it is possible to prevent wasteful movement of the cutting tool relative to the commutator material from the other side in the axial direction to the other side, thereby improving production efficiency.
In particular, according to the method for manufacturing a commutator according to claim 1, after the outer peripheral surface of the commutator material is roughly cut with a cutting tool in the first step, the outer peripheral surface of the commutator material is cut with the cutting tool in the second step. Since the finish cutting is performed, the quality of the commutator finish (for example, quality related to roundness, level difference between segments, surface roughness of the outer peripheral surface, complete removal of burrs, etc.) can be ensured while improving production efficiency.
Moreover, according to the method for manufacturing a commutator according to claim 1, a rough cutting blade surface for rough cutting the outer peripheral surface of the commutator material and a finish cutting for finishing cutting the outer peripheral surface of the commutator material. A cutting tool having a cutting edge surface is used. Therefore, it is not necessary to use dedicated cutting tools for rough cutting (first process) and finishing cutting (second process). For this reason, separate cutting tools are used for rough cutting and finishing cutting, each cutting tool is exchanged between rough cutting and finishing cutting, and the cutting tool is optimized for rough cutting and finishing cutting. There is no need to tilt it at an angle. Thereby, production efficiency can be further improved.
According to the commutator manufacturing method of claim 1, the angle θ1 formed between the rough cutting blade surface and the axial surface of the commutator material, and the axial surface of the finish cutting blade surface and the commutator material. A cutting tool satisfying θ1 ≧ θ2 in relation to the angle θ2 formed by Thereby, it is possible to perform rough cutting and finish cutting of the outer peripheral surface of the commutator material with one cutting tool.

請求項２に記載の整流子の製造方法は、請求項１に記載の整流子の製造方法において、前記第一工程の終了後で前記第二工程の開始前に、前記切削工具を前記第一工程における終了位置から前記整流子素材の軸方向一方側へ反転移動させた後に前記整流子素材に対し前記整流子素材の径方向内側へ相対移動させる、ことを特徴とする。   The commutator manufacturing method according to claim 2 is the commutator manufacturing method according to claim 1, wherein the cutting tool is moved to the first after the end of the first step and before the start of the second step. It is characterized in that the commutator material is relatively moved inward in the radial direction of the commutator material after being reversely moved from the end position in the process to one side in the axial direction of the commutator material.

仮に、第一工程の終了後で第二工程の開始前に、切削工具を第一工程における終了位置から整流子素材に対し整流子素材の径方向内側へ相対移動させて第二工程に向けての切り込み動作を行うようにした場合には、この第二工程に向けての切り込み動作のときに、切削工具の整流子素材に対する切削体積が大きくなり、この結果、切削工具に作用する切削抵抗が増加して切削工具の摩耗促進や整流子の仕上がりの品質（例えば、真円度、各セグメント間の段差、外周面の表面粗さ、バリの完全除去等に関する品質）が低下する虞がある。   Temporarily, after the end of the first step and before the start of the second step, the cutting tool is moved relative to the commutator material from the end position in the first step to the inside of the commutator material in the radial direction, toward the second step. When the cutting operation is performed, the cutting volume with respect to the commutator material of the cutting tool increases during the cutting operation toward the second step, and as a result, the cutting resistance acting on the cutting tool is reduced. There is a possibility that the wear acceleration of the cutting tool and the quality of the finish of the commutator (for example, the quality related to roundness, the level difference between the segments, the surface roughness of the outer peripheral surface, the complete removal of burrs, etc.) may decrease.

この点、請求項２に記載の整流子の製造方法によれば、第一工程の終了後で第二工程の開始前に、切削工具を第一工程における終了位置から整流子素材の軸方向一方側へ反転移動させた後に整流子素材に対し整流子素材の径方向内側へ相対移動（いわゆる二段階移動）させて第二工程に向けての切り込み動作を行う。従って、第二工程に向けての切り込み動作のときに、切削工具の整流子素材に対する切削体積を小さくでき、切削工具に作用する切削抵抗を減少させることができる。これにより、切削工具の摩耗促進や整流子の仕上がりの品質（例えば、真円度、各セグメント間の段差、外周面の表面粗さ、バリの完全除去等に関する品質）が低下することを抑制することができる。   In this regard, according to the method for manufacturing a commutator according to claim 2, the cutting tool is moved from the end position in the first step to the axial direction of the commutator material after the end of the first step and before the start of the second step. After the reversal movement to the side, the commutator material is moved relative to the inside of the commutator material in the radial direction (so-called two-stage movement) to perform a cutting operation toward the second step. Therefore, the cutting volume with respect to the commutator material of the cutting tool can be reduced during the cutting operation toward the second step, and the cutting resistance acting on the cutting tool can be reduced. This suppresses the deterioration of cutting tool wear acceleration and commutator finish quality (for example, roundness, level difference between segments, surface roughness of the outer peripheral surface, and complete removal of burrs). be able to.

請求項３に記載の整流子の製造方法は、請求項１に記載の整流子の製造方法において、前記第一工程の終了後で前記第二工程の開始前に、前記切削工具を前記第一工程における終了位置から前記整流子素材の軸方向一方側へ反転移動させつつ前記整流子素材に対し前記整流子素材の径方向内側へ相対移動させる、ことを特徴とする。   The commutator manufacturing method according to claim 3 is the commutator manufacturing method according to claim 1, wherein the cutting tool is moved to the first after the end of the first step and before the start of the second step. It is characterized by moving relative to the commutator material radially inward of the commutator material while being reversely moved from the end position in the process to one side in the axial direction of the commutator material.

請求項３に記載の整流子の製造方法によれば、第一工程の終了後で第二工程の開始前に、切削工具を第一工程における終了位置から整流子素材の軸方向一方側へ反転移動させつつ整流子素材に対し整流子素材の径方向内側へ相対移動させて第二工程に向けての切り込み動作を行う。従って、第二工程に向けての切り込み動作のときに、切削工具の整流子素材に対する切削体積を小さくでき、切削工具に作用する切削抵抗を減少させることができる。これにより、切削工具の摩耗促進や整流子の仕上がりの品質（例えば、真円度、各セグメント間の段差、外周面の表面粗さ、バリの完全除去等に関する品質）が低下することを抑制することができる。   According to the method for manufacturing a commutator according to claim 3, the cutting tool is reversed from the end position in the first step to the one side in the axial direction of the commutator material after the end of the first step and before the start of the second step. While moving, the commutator material is moved relative to the inside of the commutator material in the radial direction to perform a cutting operation toward the second step. Therefore, the cutting volume with respect to the commutator material of the cutting tool can be reduced during the cutting operation toward the second step, and the cutting resistance acting on the cutting tool can be reduced. This suppresses the deterioration of cutting tool wear acceleration and commutator finish quality (for example, roundness, level difference between segments, surface roughness of the outer peripheral surface, and complete removal of burrs). be able to.

また、これに加えて、切削工具を第一工程における終了位置から整流子素材の軸方向一方側へ反転移動させつつ整流子素材に対し整流子素材の径方向内側へ相対移動させることで、上述のいわゆる二段階移動を行う場合に比して、切削工具の移動経路を短くできる。これにより、第一工程と第二工程との間の時間が短くなるので、生産効率をより一層向上させることができる。   Further, in addition to this, the cutting tool is moved relative to the commutator material radially inward with respect to the commutator material while being reversed and moved from the end position in the first step to the one side in the axial direction of the commutator material. Compared with the case where the so-called two-stage movement is performed, the moving path of the cutting tool can be shortened. Thereby, since the time between a 1st process and a 2nd process becomes short, production efficiency can be improved further.

Control means, wherein the control means controls the driving of the circumferential drive means so that the cutting tool is moved relative to the commutator material in the circumferential direction of the commutator material. It is a first flank formed on the cutting tool of the cutting tool by controlling the driving of the axial driving means so that the tool is relatively moved from one axial side to the other side of the commutator material. Using the rough cutting edge A first step of roughing and cutting the outer peripheral surface of the commutator material, and controlling the driving of the circumferential drive means so that the cutting tool is moved relative to the commutator material in the circumferential direction of the commutator material. However, by controlling the driving of the axial drive means so that the cutting tool is relatively moved from the other axial side of the commutator material to the other side, the second flank formed on the cutting tool Performing a second step of finishing cutting the outer peripheral surface of the commutator material using a certain cutting blade surface, and the cutting tool includes the rough cutting blade surface and the axial surface of the commutator material. The relationship between the first clearance angle θ1 that is an angle between the first clearance angle θ1 and the second clearance angle θ2 that is the angle between the finishing cutting blade surface and the axial surface of the commutator material satisfies θ1 ≧ θ2. It is configured to be .

Direction driving means, and the control means controls the driving of the axial direction driving means and the radial direction driving means after the completion of the execution of the first step and before the execution of the second step. Is moved relative to the commutator material inward in the radial direction of the commutator material while being reversely moved from the end position in the first step to one side in the axial direction of the commutator material.

請求項６に記載の整流子の製造装置によれば、制御手段における第一ステップの実行終了後で第二ステップの実行開始前に、軸方向駆動手段及び径方向駆動手段の駆動が制御されて切削工具が第一ステップにおける終了位置から整流子素材の軸方向一方側へ反転移動されつつ整流子素材に対し整流子素材の径方向内側へ相対移動される。従って、第二ステップに向けての切り込み動作のときに、切削工具の整流子素材に対する切削体積を小さくでき、切削工具に作用する切削抵抗を減少させることができる。これにより、切削工具の摩耗促進や整流子の仕上がりの品質（例えば、真円度、各セグメント間の段差、外周面の表面粗さ、バリの完全除去等に関する品質）が低下することを抑制することができる。 According to the commutator manufacturing apparatus of the sixth aspect , the driving of the axial driving means and the radial driving means is controlled after the execution of the first step in the control means and before the execution of the second step. The cutting tool is moved relative to the commutator material inward in the radial direction of the commutator material while being reversely moved from the end position in the first step to one side in the axial direction of the commutator material. Therefore, during the cutting operation toward the second step, the cutting volume of the cutting tool with respect to the commutator material can be reduced, and the cutting resistance acting on the cutting tool can be reduced. This suppresses the deterioration of cutting tool wear acceleration and commutator finish quality (for example, roundness, level difference between segments, surface roughness of the outer peripheral surface, and complete removal of burrs). be able to.

また、これに加えて、切削工具が第一ステップにおける終了位置から整流子素材の軸方向一方側へ反転移動されつつ整流子素材に対し整流子素材の径方向内側へ相対移動されることで、上述のいわゆる二段階移動される場合に比して、切削工具の移動経路を短くできる。これにより、第一ステップと第二ステップとの間の時間が短くなるので、生産効率をより一層向上させることができる。   In addition to this, the cutting tool is moved relative to the commutator material radially inward from the commutator material while being reversely moved from the end position in the first step to the one side in the axial direction of the commutator material. The moving path of the cutting tool can be shortened as compared with the above-described so-called two-stage movement. Thereby, since the time between the first step and the second step is shortened, the production efficiency can be further improved.

Move from the other side in the axial direction (riser side; Z2 side) to one side (Z1 side). At this time, the cutting tool 16 is moved so that the finish cutting blade surface 38C of the cutting tool 38 shown in FIG. 3C faces the traveling direction (that is, one side in the axial direction; Z1 side). Thereby, the outer peripheral surface of the commutator material 56 is finish-cut from the other side in the axial direction to one side.

続いて、制御回路２６は、軸方向駆動用モータ２２及び径方向駆動用モータ２４の駆動を制御し、切削工具１６を図２の矢印（４）で示されるように整流子素材５６の軸方向一方側（Ｚ１側）から原点位置に復帰させる。   Subsequently, the control circuit 26 controls the driving of the axial direction driving motor 22 and the radial direction driving motor 24 so that the cutting tool 16 is moved in the axial direction of the commutator material 56 as indicated by an arrow (4) in FIG.

These are omitted, and reference is made to FIG. 1 for these. In the commutator manufacturing apparatus 110 according to the comparative example, the same reference numerals are used for the same configuration as the commutator manufacturing apparatus 10 according to the embodiment of the present invention.

比較例に係る整流子の製造方法では、荒削り切削加工と仕上げ切削加工とでそれぞれ別々の整流子の製造装置１１０が使用される。つまり、図８に示される整流子の製造装置１０は、荒削り切削加工用とされており、図９に示される整流子の製造装置１１０は、仕上げ切削加工用とされている。   In the commutator manufacturing method according to the comparative example, separate commutator manufacturing apparatuses 110 are used for rough cutting and finish cutting, respectively. That is, the commutator manufacturing apparatus 10 shown in FIG. 8 is for rough cutting, and the commutator manufacturing apparatus 110 shown in FIG. 9 is for finishing cutting.

図１０には、比較例に係る整流子の製造装置１１０に備えられた切削工具１１６が示されている。切削工具１１６は、図１０に示されるように、ホルダ１３６と切削バイト１３８とを有して構成されている。切削バイト１３８は、ホルダ１３６の先端部に交換可能に保持されており、図１０（Ｃ）に示されるように、すくい面１３８Ａと、第一の逃げ面１３８Ｂと、第二の逃げ面１３８Ｃと、を有する構成とされている。また、切削バイト１３８の刃先先端１３８Ｄは、シャープエッジ形状とされている。   FIG. 10 shows a cutting tool 116 provided in the commutator manufacturing apparatus 110 according to the comparative example.

そして、この比較例に係る整流子の製造装置１１０では、次の方法で、整流子の製造が行われる。   In the commutator manufacturing apparatus 110 according to this comparative example, commutators are manufactured by the following method.

すなわち、図８に示される荒削り切削加工用の整流子の製造装置１１０において、制御回路２６は、入力操作部１８に加工開始指令が入力されると、軸方向駆動用モータ２２及び径方向駆動用モータ２４の駆動を制御し、切削工具１１６を図８の矢印（１）で示されるように原点位置から整流子素材５６の軸方向一方側（Ｚ１側）に移動させる。なお、このとき、切削バイト１３８の先端の位置は、次の荒削り切削加工の切り込み量に合わせて設定される。   That is, in the commutator manufacturing apparatus 110 for rough cutting shown in FIG. 8, when a machining start command is input to the input operation unit 18, the control circuit 26 and the axial driving motor 22 and the radial driving motor The driving of the motor 24 is controlled, and the cutting tool 116 is moved from the origin position to one side (Z1 side) in the axial direction of the commutator material 56 as indicated by an arrow (1) in FIG. At this time, the position of the tip of the cutting tool 138 is set in accordance with the cutting amount of the next rough cutting process.

続いて、制御回路２６は、周方向駆動用モータ２０の駆動を制御し、駆動プーリ３２を回転させる。これにより、駆動ベルト３０が回転されて、電機子５０と共に整流子素材５６が回転される。   Subsequently, the control circuit 26 controls driving of the circumferential driving motor 20 to rotate the driving pulley 32. As a result, the drive belt 30 is rotated, and the commutator material 56 is rotated together with the armature 50.

（第一工程：荒削り切削加工）
続いて、制御回路２６は、整流子素材５６を回転させながら、軸方向駆動用モータ２２の駆動を制御し、切削工具１１６を図８の矢印（２）で示されるように整流子素材５６の軸方向一方側（Ｚ１側）から他方側（ライザ側；Ｚ２側）に移動させる。このとき、切削工具１１６は、図１０（Ｃ）に示される切削バイト１３８の第一の逃げ面１３８Ｂが進行方向（つまり軸方向他方側；Ｚ２側）を向くように移動される。これにより、整流子素材５６の外周面が軸方向一方側から他方側に荒削り切削される。 (First step: rough cutting)
Subsequently, the control circuit 26 controls the driving of the axial direction driving motor 22 while rotating the commutator material 56, and the cutting tool 116 is moved to the commutator material 56 as indicated by an arrow (2) in FIG. 8.

At this time, the cutting tool 116 is moved so that the first flank 138B of the cutting tool 138 shown in FIG. 10C faces the traveling direction (that is, the other side in the axial direction; Z2 side). Thereby, the outer peripheral surface of the commutator material 56 is rough cut from one side in the axial direction to the other side.

（第一工程の終了後で第二工程の開始前）
続いて、制御回路２６は、径方向駆動用モータ２４の駆動を制御し、切削工具１１６を図８の矢印（３）で示される如く第一工程における終了位置から整流子素材５６の径方向外側へ退避させる。そして、その後、制御回路２６は、軸方向駆動用モータ２２及び径方向駆動用モータ２４の駆動を制御し、切削工具１１６を図８の矢印（４）で示されるように上述の退避位置から原点位置に復帰させる。 (After the end of the first step and before the start of the second step)

そして、整流子５８は、上述の荒削り切削加工の後、図９に示される如く、仕上げ切削加工用の整流子の製造装置１１０に搬送される。なお、荒削り切削加工と仕上げ切削加工とで共通の整流子の製造装置１１０を用いる場合には、切削バイト１３８を荒削り切削加工用から仕上げ切削加工用に交換したり、次の仕上げ切削加工に合わせて切削工具１１６を最適角度に傾斜させたりする必要がある。   Then, the commutator 58 is conveyed to the commutator manufacturing apparatus 110 for finish cutting as shown in FIG. 9 after the above rough cutting. When the commutator manufacturing apparatus 110 that is common to rough cutting and finishing cutting is used, the cutting tool 138 is exchanged from rough cutting to finishing cutting, or to the next finishing cutting. Therefore, it is necessary to incline the cutting tool 116 at an optimum angle.

（第二工程：仕上げ切削加工）
そして、図９に示される仕上げ切削加工用の整流子の製造装置１１０において、制御回路２６は、入力操作部１８に加工開始指令が入力されると、軸方向駆動用モータ２２及び径方向駆動用モータ２４の駆動を制御し、切削工具１１６を図９の矢印（５）で示されるように原点位置から整流子素材５６の軸方向一方側（Ｚ１側）に再び移動させる。なお、このとき、切削バイト１３８の先端の位置は、次の仕上げ切削加工の切り込み量に合わせて設定される。 (Second process: finish cutting)
Then, in the finishing cutting commutator manufacturing apparatus 110 shown in FIG. 9, when the machining start command is input to the input operation unit 18, the control circuit 26 and the axial driving motor 22 and the radial driving motor The drive of the motor 24 is controlled, and the cutting tool 116 is again moved from the origin position to one side (Z1 side) in the axial direction of the commutator material 56 as indicated by an arrow (5) in FIG. At this time, the position of the tip of the cutting tool 138 is set in accordance with the cutting amount of the next finish cutting process.

続いて、制御回路２６は、周方向駆動用モータ２０の駆動を制御し、駆動プーリ３２を回転させる。これにより、駆動ベルト３０が回転されて、電機子５０と共に整流子素材５６が回転される。   Subsequently, the control circuit 26 controls driving of the circumferential driving motor 20 to rotate the driving pulley 32. As a result, the drive belt 30 is rotated, and the commutator material 56 is rotated together with the armature 50.

（第二工程：仕上げ切削加工）
続いて、制御回路２６は、整流子素材５６を回転させながら、軸方向駆動用モータ２２の駆動を制御し、切削工具１１６を図９の矢印（６）で示されるように整流子素材５６の軸方向一方側（Ｚ１側）から他方側（ライザ側；Ｚ２側）に移動させる。このとき、切削工具１１６は、図１０（Ｃ）に示される切削バイト１３８の第一の逃げ面１３８Ｂが進行方向（つまり軸方向他方側；Ｚ２側）を向くように移動される。これにより、整流子素材５６の外周面が軸方向一方側から他方側に仕上げ切削される。 (Second process: finish cutting)
Subsequently, the control circuit 26 controls the driving of the axial drive motor 22 while rotating the commutator material 56, and the cutting tool 116 is moved to the commutator material 56 as indicated by an arrow (6) in FIG. 9. Move from one axial side (Z1 side) to the other side (riser side; Z2 side). At this time, the cutting tool 116 is moved so that the first flank 138B of the cutting tool 138 shown in FIG. 10C faces the traveling direction (that is, the other side in the axial direction; Z2 side). Thereby, the outer peripheral surface of the commutator material 56 is finish-cut from the one side in the axial direction to the other side.

続いて、制御回路２６は、径方向駆動用モータ２４の駆動を制御し、切削工具１１６を図９の矢印（７）で示される如く第一工程における終了位置から整流子素材５６の径方向外側へ退避させる。そして、その後、制御回路２６は、軸方向駆動用モータ２２及び径方向駆動用モータ２４の駆動を制御し、切削工具１１６を図９の矢印（８）で示されるように上述の退避位置から原点位置に復帰させる。   Subsequently, the control circuit 26 controls the driving of the radial driving motor 24 and moves the cutting tool 116 radially outward of the commutator material 56 from the end position in the first step as shown by the arrow (7) in FIG. Evacuate to. Thereafter, the control circuit 26 controls the driving of the axial direction driving motor 22 and the radial direction driving motor 24, and the cutting tool 116 is moved from the retraction position to the origin as shown by the arrow (8) in FIG. Return to position.

（バリ取り工程）
続いて、整流子素材５６は、上述の切削加工の後、図７に示される如く、バリ取り工程に搬送される。そして、このバリ取り工程において、整流子素材５６は、バリ取り装置のナイロンブラシ４０によってアンダーカット溝に残されたバリ等を除去される。比較例に係る整流子の製造方法では、以上の要領により、整流子素材５６から整流子５８が製造される。 (Deburring process)
Subsequently, the commutator material 56 is transported to the deburring step as shown in FIG. 7 after the above-described cutting process. In this deburring step, the commutator material 56 is removed of the burrs and the like left in the undercut groove by the nylon brush 40 of the deburring device. In the commutator manufacturing method according to the comparative example, the commutator 58 is manufactured from the commutator material 56 in the manner described above.

しかしながら、上述の比較例に係る整流子の製造方法のように、整流子素材５６を切削して整流子素材５６から整流子５８を製造する際に、切削工具１１６を整流子素材５６に対し軸方向一方側（Ｚ１側）から他方側（Ｚ２側）へ相対移動させるとき（往路移動時）のみ整流子素材５６の外周面を切削し、切削工具１１６を整流子素材５６に対し軸方向他方側（Ｚ２側）から一方側（Ｚ１側）へ相対移動させるとき（復路移動時）を原点位置に復帰させるためのエアカットとすると、この切削工具１１６を整流子素材５６に対し軸方向他方側（Ｚ２側）から一方側（Ｚ１側）へ相対移動させることが無駄となり、生産効率が低下する。   However, when the commutator material 56 is cut and the commutator 58 is manufactured from the commutator material 56 as in the commutator manufacturing method according to the comparative example described above, the cutting tool 116 is pivoted with respect to the commutator material 56. The outer peripheral surface of the commutator material 56 is cut only when the relative movement from one direction (Z1 side) to the other side (Z2 side) is performed (during forward movement), and the cutting tool 116 is axially opposite to the commutator material 56. When the air cut for returning to the home position is performed when the relative movement from the (Z2 side) to the one side (Z1 side) (return movement) is performed, the cutting tool 116 is moved to the commutator material 56 in the other axial direction ( The relative movement from the Z2 side to the one side (Z1 side) is useless, and the production efficiency is reduced.

これに対し、本発明の一実施形態に係る整流子の製造方法によれば、図２に示されるように、整流子素材５６を切削して整流子素材５６から整流子５８を製造する際に、切削工具１６を整流子素材５６に対し軸方向一方側（Ｚ１側）から他方側（Ｚ２側）へ相対移動させるとき（往路移動時）に加えて、切削工具１６を整流子素材５６に対し軸方向他方側（Ｚ２側）から一方側（Ｚ１側）へ相対移動させるとき（復路移動時）にも、整流子素材５６の外周面を切削工具１６により切削する。従って、切削工具１６を整流子素材５６に対し軸方向他方側（Ｚ２側）から一方側（Ｚ１側）へ相対移動させることが無駄となることを防止できるので、これにより、生産効率を向上させることができる。   In contrast, according to the method for manufacturing a commutator according to an embodiment of the present invention, as shown in FIG. 2, when the commutator material 56 is cut to manufacture the commutator 58 from the commutator material 56. In addition to when the cutting tool 16 is moved relative to the commutator material 56 in the axial direction from one side (Z1 side) to the other side (Z2 side) (during forward movement), the cutting tool 16 is moved relative to the commutator material 56. The outer peripheral surface of the commutator material 56 is also cut by the cutting tool 16 when the relative movement is made from the other side (Z2 side) in the axial direction to the one side (Z1 side) (when moving in the return path). Therefore, it is possible to prevent wasteful movement of the cutting tool 16 relative to the commutator material 56 from the other axial side (Z2 side) to the one side (Z1 side), thereby improving production efficiency. be able to.

しかも、本発明の一実施形態に係る整流子の製造方法によれば、第一工程において整流子素材５６の外周面を切削工具１６により荒削り切削した後に、第二工程において整流子素材５６の外周面を切削工具１６により仕上げ切削するので、生産効率を向上させつつ、整流子５８の仕上がりの品質（例えば、真円度、各セグメント間の段差、外周面の表面粗さ、バリの完全除去等に関する品質）を確保できる。   Moreover, according to the method for manufacturing a commutator according to an embodiment of the present invention, after the outer peripheral surface of the commutator material 56 is roughly cut by the cutting tool 16 in the first step, the outer periphery of the commutator material 56 in the second step. Since the surface is finish-cut with the cutting tool 16, the quality of the finish of the commutator 58 (for example, roundness, steps between segments, surface roughness of the outer peripheral surface, complete removal of burrs, etc., while improving production efficiency) Quality).

ここで、仮に、第一工程の終了後で第二工程の開始前に、例えば、図６の矢印（Ａ）で示される如く、切削工具１６を第一工程における終了位置（二点鎖線で示される位置）から整流子素材５６に対し整流子素材５６の径方向内側（Ｒ１側）へ相対移動させて第二工程に向けての切り込み動作を行うようにした場合には、この第二工程に向けての切り込み動作のときに、切削工具１６の整流子素材５６に対する切削体積（つまり、斜線Ｑ３で示される部分）が大きくなり、この結果、切削工具１６に作用する切削抵抗が増加して切削バイト３８の摩耗促進や整流子５８の仕上がりの品質（例えば、真円度、各セグメント間の段差、外周面の表面粗さ、バリの完全除去等に関する品質）が低下する虞がある。   Here, for example, after the first step is finished and before the second step is started, for example, as indicated by an arrow (A) in FIG. If the cutting operation toward the second step is performed by moving the commutator material 56 relative to the commutator material 56 in the radial direction (R1 side) from the position of the commutator material 56, the second step When the cutting operation is directed toward, the cutting volume of the cutting tool 16 with respect to the commutator material 56 (that is, the portion indicated by the oblique line Q3) increases, and as a result, the cutting resistance acting on the cutting tool 16 increases and cutting is performed. There is a possibility that the wear quality of the cutting tool 38 and the quality of the finish of the commutator 58 (for example, quality related to roundness, level difference between the segments, surface roughness of the outer peripheral surface, complete removal of burrs, etc.) may be deteriorated.

この点、本発明の一実施形態に係る整流子の製造方法によれば、第一工程の終了後で第二工程の開始前に、図４の矢印（Ａ）、（Ｂ）で示される如く、切削工具１６を第一工程における終了位置（二点鎖線で示される位置）から整流子素材５６の軸方向一方側（Ｚ１側）へ反転移動させた後に整流子素材５６に対し整流子素材５６の径方向内側（Ｒ１側）へ相対移動（いわゆる二段階移動）させて第二工程に向けての切り込み動作を行う。従って、第二工程に向けての切り込み動作のときに、切削工具１６の整流子素材５６に対する切削体積（つまり、斜線Ｑ１で示される部分）を小さくでき、切削工具１６に作用する切削抵抗を減少させることができる。これにより、切削バイト３８の摩耗促進や整流子５８の仕上がりの品質（例えば、真円度、各セグメント間の段差、外周面の表面粗さ、バリの完全除去等に関する品質）が低下することを抑制することができる。   In this regard, according to the method of manufacturing a commutator according to an embodiment of the present invention, as shown by arrows (A) and (B) in FIG. 4 after the end of the first step and before the start of the second step. Then, the cutting tool 16 is reversely moved from the end position in the first step (the position indicated by the two-dot chain line) to one side (Z1 side) in the axial direction of the commutator material 56, and then the commutator material 56 with respect to the commutator material 56. Is moved relative to the inner side in the radial direction (R1 side) (so-called two-stage movement) to perform a cutting operation toward the second step. Therefore, during the cutting operation toward the second step, the cutting volume of the cutting tool 16 with respect to the commutator material 56 (that is, the portion indicated by the oblique line Q1) can be reduced, and the cutting resistance acting on the cutting tool 16 is reduced. Can be made. As a result, the wear acceleration of the cutting tool 38 and the quality of the finish of the commutator 58 (for example, quality related to roundness, level difference between segments, surface roughness of the outer peripheral surface, complete removal of burrs, etc.) are reduced. Can be suppressed.

また、本発明の一実施形態に係る整流子の製造方法によれば、整流子素材５６の外周面を荒削り切削するための荒削り切削用刃面３８Ｂと、整流子素材５６の外周面を仕上げ切削するための仕上げ切削用刃面３８Ｃと、を有する切削バイト３８を用いる。従って、荒削り切削加工（第一工程）と仕上げ切削加工（第二工程）とでそれぞれ専用の切削バイトを用いる必要が無い。このため、荒削り切削加工と仕上げ切削加工とで切削装置を別々としたり、荒削り切削加工と仕上げ切削加工とで各切削バイトを交換したり、荒削り切削加工及び仕上げ切削加工に合わせて切削工具１６を最適角度に傾斜させたりする必要が無い。これにより、生産効率をより一層向上させることができる。   In addition, according to the commutator manufacturing method according to an embodiment of the present invention, the rough cutting blade surface 38B for rough cutting the outer peripheral surface of the commutator material 56 and the outer peripheral surface of the commutator material 56 are finish-cut. A cutting tool 38 having a finish cutting blade surface 38C for the purpose is used. Therefore, it is not necessary to use dedicated cutting tools for rough cutting (first process) and finishing cutting (second process). For this reason, the cutting tool is used separately for rough cutting and finishing cutting, each cutting tool is exchanged between rough cutting and finishing cutting, and the cutting tool 16 is used in accordance with rough cutting and finishing cutting. There is no need to tilt to the optimum angle. Thereby, production efficiency can be further improved.

さらに、本発明の一実施形態に係る整流子の製造方法によれば、荒削り切削用刃面３８Ｂと整流子素材５６の軸方向表面５６Ａとのなす角度θ１と、仕上げ切削用刃面３８Ｃと整流子素材５６の軸方向表面５６Ａとのなす角度θ２との関係がθ１≧θ２を満足する切削バイト３８を用いる。これにより、一つの切削バイト３８により整流子素材５６の外周面の荒削り切削と仕上げ切削を行うことが可能となる。   Furthermore, according to the commutator manufacturing method according to the embodiment of the present invention, the angle θ1 formed between the rough cutting blade surface 38B and the axial surface 56A of the commutator material 56, the finish cutting blade surface 38C, and the rectification. A cutting tool 38 having a relationship of θ1 ≧ θ2 with respect to the angle θ2 formed with the axial surface 56A of the child material 56 is used. Thereby, it is possible to perform rough cutting and finish cutting of the outer peripheral surface of the commutator material 56 with one cutting tool 38.

以上、本発明の一実施形態について説明したが、本発明は、上記に限定されるものでなく、その主旨を逸脱しない範囲内において種々変形して実施することが可能であることは勿論である。   As mentioned above, although one Embodiment of this invention was described, this invention is not limited above, Of course, it can change and implement variously within the range which does not deviate from the main point. .

例えば、上記実施形態では、第一工程の終了後で第二工程の開始前に、図４に示されるように、切削工具１６を第一工程における終了位置（二点鎖線で示される位置）から整流子素材５６の軸方向一方側（Ｚ１側）へ反転移動させた後に整流子素材５６に対し整流子素材５６の径方向内側（Ｒ１側）へ相対移動（いわゆる二段階移動）させて第二工程に向けての切り込み動作を行っていたが、次のようにしても良い。   For example, in the above embodiment, after the end of the first step and before the start of the second step, as shown in FIG. 4, the cutting tool 16 is moved from the end position in the first step (position indicated by a two-dot chain line). After the commutator material 56 is reversed and moved to one side (Z1 side) in the axial direction, the commutator material 56 is moved relative to the radially inner side (R1 side) of the commutator material 56 (so-called two-stage movement) to be second. Although the cutting operation for the process is performed, the following may be performed.

すなわち、第一工程の終了後で第二工程の開始前に、図５の矢印（Ａ）で示される如く、切削工具１６を第一工程における終了位置（二点鎖線で示される位置）から整流子素材５６の軸方向一方側（Ｚ１側）へ反転移動させつつ整流子素材５６に対し整流子素材５６の径方向内側（Ｒ１側）へ相対移動させて第二工程に向けての切り込み動作を行っても良い。   That is, after the end of the first step and before the start of the second step, as shown by the arrow (A) in FIG. 5, the cutting tool 16 is rectified from the end position in the first step (the position indicated by the two-dot chain line). The reversing movement to the one side (Z1 side) in the axial direction of the child material 56 is made to move relative to the radially inner side (R1 side) of the commutator material 56 with respect to the commutator material 56 to perform a cutting operation toward the second step. You can go.

このようにすれば、第二工程に向けての切り込み動作のときに、切削工具１６の整流子素材５６に対する切削体積（つまり、斜線Ｑ２で示される部分）を小さくでき、切削工具１６に作用する切削抵抗を減少させることができる。これにより、切削バイト３８の摩耗促進や整流子５８の仕上がりの品質（例えば、真円度、各セグメント間の段差、外周面の表面粗さ、バリの完全除去等に関する品質）が低下することを抑制することができる。   In this way, the cutting volume of the cutting tool 16 relative to the commutator material 56 (that is, the portion indicated by the hatched line Q2) can be reduced during the cutting operation toward the second step, and this acts on the cutting tool 16. Cutting resistance can be reduced. As a result, the wear acceleration of the cutting tool 38 and the quality of the finish of the commutator 58 (for example, quality related to roundness, level difference between segments, surface roughness of the outer peripheral surface, complete removal of burrs, etc.) are reduced. Can be suppressed.

また、これに加えて、切削工具１６を第一工程における終了位置から整流子素材５６の軸方向一方側（Ｚ１側）へ反転移動させつつ整流子素材５６に対し整流子素材５６の径方向内側（Ｒ１側）へ相対移動させることで、上述のいわゆる二段階移動を行う場合（図５の場合）に比して、切削工具１６の移動経路を短くできる。これにより、第一工程と第二工程との間の時間が短くなるので、生産効率をより一層向上させることができる。   In addition to this, the cutting tool 16 is reversely moved from the end position in the first step to the one axial side (Z1 side) of the commutator material 56 while the commutator material 56 is radially inward of the commutator material 56. By making the relative movement to the (R1 side), the movement path of the cutting tool 16 can be shortened as compared with the case of performing the so-called two-stage movement (in the case of FIG. 5). Thereby, since the time between a 1st process and a 2nd process becomes short, production efficiency can be improved further.

また、上記実施形態では、回転機構１４及び周方向駆動用モータ２０を用いて、切削工具１６を整流子素材５６に対し整流子素材５６の周方向に移動させていたが、その他の周方向駆動手段を用いて、切削工具１６が整流子素材５６に対し整流子素材５６の周方向に相対移動されるように、切削工具１６及び整流子素材５６の少なくとも一つを移動させるようにしても良い。   In the above embodiment, the cutting tool 16 is moved in the circumferential direction of the commutator material 56 with respect to the commutator material 56 by using the rotation mechanism 14 and the circumferential drive motor 20. Means may be used to move at least one of the cutting tool 16 and the commutator material 56 such that the cutting tool 16 is moved relative to the commutator material 56 in the circumferential direction of the commutator material 56. .

また、上記実施形態では、軸方向駆動用モータ２２を用いて、切削工具１６を整流子素材５６に対し整流子素材５６の軸方向に移動させていたが、その他の軸方向駆動手段を用いて、切削工具１６が整流子素材５６に対し整流子素材５６の軸方向に相対移動されるように、切削工具１６及び整流子素材５６の少なくとも一つを移動させるようにしても良い。   Moreover, in the said embodiment, although the cutting tool 16 was moved to the axial direction of the commutator raw material 56 with respect to the commutator raw material 56 using the axial direction drive motor 22, other axial direction drive means were used. Alternatively, at least one of the cutting tool 16 and the commutator material 56 may be moved so that the cutting tool 16 is moved relative to the commutator material 56 in the axial direction of the commutator material 56.

また、上記実施形態では、径方向駆動用モータ２４を用いて、切削工具１６を整流子素材５６に対し整流子素材５６の径方向に移動させていたが、その他の径方向駆動手段を用いて、切削工具１６が整流子素材５６に対し整流子素材５６の径方向に相対移動されるように、切削工具１６及び整流子素材５６の少なくとも一つを移動させるようにしても良い。   Moreover, in the said embodiment, although the cutting tool 16 was moved to the radial direction of the commutator raw material 56 with respect to the commutator raw material 56 using the radial direction drive motor 24, other radial direction drive means were used. Alternatively, at least one of the cutting tool 16 and the commutator material 56 may be moved so that the cutting tool 16 is moved relative to the commutator material 56 in the radial direction of the commutator material 56.
