Description

本発明は、ブラシレスモータ等において、ロータとステータを軸芯方向に相対移動させてロータをステータに組み付ける装置に関する。   The present invention relates to a device for assembling a rotor to a stator by relatively moving the rotor and the stator in the axial direction in a brushless motor or the like.

各種装置の駆動源として、耐久性に優れたブラシレスモータが使用されている。このモータは、電磁コイルを装着してハウジング内に固設されたステータと、ハウジングに軸支されてステータ内に収容配置されたロータとからなる。ロータは着磁されており、ステータ内周面との間に僅かな空隙を形成している。   As a drive source for various devices, a brushless motor having excellent durability is used. This motor includes a stator mounted with an electromagnetic coil and fixed in the housing, and a rotor supported by the housing and accommodated in the stator. The rotor is magnetized, and a slight gap is formed between the rotor and the inner peripheral surface of the stator.

ブラシレスモータの組み立てに際しては、まず、薄板鋼板を積層したステータコアに導線を巻回して電磁コイルを構成し、この電磁コイルを備えたステータをハウジング内に固設する一方、ロータを着磁装置により着磁し、これをハウジングに組み付けておく。次いで、ステータ内にロータを挿入し、両者のハウジングを一体に結合している。   When assembling a brushless motor, first, a conductive wire is wound around a stator core laminated with thin steel plates to form an electromagnetic coil, and a stator having this electromagnetic coil is fixed in the housing, while the rotor is attached by a magnetizing device. Magnetize it and attach it to the housing. Next, a rotor is inserted into the stator, and both housings are joined together.

ロータの挿入にあたっては、ロータをステータに接触させないように位置決めをしているが、ロータとステータの間に大きな吸引力が作用するため、作業性を低下させる一因となっている。例えば、ロータ側のハウジングとステータ側のハウジングとの間にシール材を介装する必要がある場合、ロータがステータに急激に引き寄せられると、シール材が噛み込み等の発生により正確に組み付けられなくなる。   In inserting the rotor, the rotor is positioned so as not to contact the stator. However, since a large suction force acts between the rotor and the stator, it is a cause of reducing workability. For example, when it is necessary to interpose a sealing material between the rotor-side housing and the stator-side housing, if the rotor is suddenly drawn to the stator, the sealing material cannot be accurately assembled due to the occurrence of biting or the like. .

そこで、油圧シリンダやボールねじ等の駆動手段によって、ロータを強制的に移動させてステータ内に挿入する方法が提案されている（特許文献１参照）。
特許第３１６９８０７号公報 Therefore, a method has been proposed in which the rotor is forcibly moved and inserted into the stator by a driving means such as a hydraulic cylinder or a ball screw (see Patent Document 1).
Japanese Patent No. 3169807

しかし、この方法では、油圧シリンダやボールねじ等でロータを移動させているため、ロータの移動速度が遅く、ロータの組付に時間を要し、作業能率が低いという問題があった。   However, in this method, since the rotor is moved by a hydraulic cylinder, a ball screw, or the like, there is a problem that the moving speed of the rotor is slow, time is required for assembly of the rotor, and work efficiency is low.

本発明は、このような事情に鑑み、作業時間の短縮が可能なロータ組付装置を提供することを目的とする。   In view of such circumstances, an object of the present invention is to provide a rotor assembling apparatus that can shorten the working time.

上記課題を解決するための本発明は、ロータとステータを軸芯方向に相対移動させてロータをステータに組み付ける装置において、基台と、該基台上に上記ロータ,ステータをそれぞれ保持するロータ,ステータ保持手段と、これら保持手段の一方を上記基台に対して軸芯方向に移動自在に支持する支持手段と、上記基台上に配設したカム手段と、該カム手段と係合して上記ロータとステータの間に作用する吸引力に対して抵抗力を生じさせるべく、上記ロータ保持手段またはステータ保持手段に設けたカム係合手段とを備えたことを特徴とする。   The present invention for solving the above problems is a device for assembling a rotor to a stator by relatively moving the rotor and the stator in the axial direction, and a rotor for holding the rotor and the stator on the base, respectively, A stator holding means; a support means for supporting one of the holding means so as to be movable in the axial direction with respect to the base; a cam means disposed on the base; and engaging the cam means. The rotor holding means or cam engaging means provided on the stator holding means is provided to generate a resistance force against the attractive force acting between the rotor and the stator.

かかる構成によれば、ロータとステータが接近し、両者の間に吸引力が作用すると、この吸引力に対して抵抗力を生じさせるべく、カム係合手段がカム手段と係合するので、ロータ,ステータ保持手段の一方が他方側に急激に引き寄せられることがなくなり、ロータのステータに対する挿入が緩やかに行われる。   According to such a configuration, when the rotor and the stator approach and a suction force acts between them, the cam engagement means engages with the cam means so as to generate a resistance force against the suction force. Thus, one of the stator holding means is not suddenly drawn to the other side, and the rotor is inserted into the stator slowly.

上記カム手段は基台上に固設したカム部材で構成される一方、上記カム係合手段は、カム手段のカム面と上記基台の上面とを転動するローラ部材と、該ローラ部材を下方へ付勢するスプリング部材とで構成されているのが好ましい。   The cam means comprises a cam member fixed on the base, while the cam engaging means comprises a roller member that rolls between the cam surface of the cam means and the upper surface of the base, and the roller member. It is preferable that the spring member is biased downward.

かかる構成によれば、ローラ部材がカム手段のカム面上を転動する際に摩擦力が生じ、この摩擦力がロータとステータの間の吸引力に対し抵抗力となる。   According to such a configuration, a frictional force is generated when the roller member rolls on the cam surface of the cam means, and this frictional force becomes a resistance to the attractive force between the rotor and the stator.

上記ロータまたはステータがその端縁同士を一致させる位置まで移動した際、上記ローラ部材が係合すべき急峻部を上記カム面に形成するのが好ましい。   When the rotor or the stator moves to a position where the edges coincide with each other, it is preferable that a steep portion to be engaged with the roller member is formed on the cam surface.

かかる構成によれば、ロータまたはステータがその端縁同士を一致させる位置まで移動すると、ロータとステータの間の吸引力が最大になるが、ローラ部材がカム面の急峻部に係合して大きな抵抗力を発生させる。   According to such a configuration, when the rotor or the stator moves to a position where the edges thereof coincide with each other, the suction force between the rotor and the stator becomes maximum, but the roller member engages with the steep portion of the cam surface and becomes large. Generate resistance.

本発明によれば、カム手段とカム係合手段との係合によって、ロータとステータの間の吸引力に対し抵抗力が発生するので、油圧シリンダやボールねじ等の駆動手段を用いなくても、ロータの挿入を緩やかに行うことができる。よって、作業時間が短縮し、作業能率の向上が図られる。   According to the present invention, the engagement between the cam means and the cam engagement means generates a resistance force against the attractive force between the rotor and the stator, so that it is not necessary to use a drive means such as a hydraulic cylinder or a ball screw. The rotor can be inserted slowly. Therefore, the work time is shortened and the work efficiency is improved.

以下、本発明の実施形態を添付図面に基づいて詳細に説明する。   Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

図１は本発明のロータ組付装置を示している。   FIG. 1 shows a rotor assembling apparatus of the present invention.

同図において、１は基台で、その上面にはロータ保持手段２を設置してある。ロータ保持手段２は、ロータＲの軸部一端をチャック機構２ａで把持し、支持手段としてのリニアガイド（図示せず）に案内されて図中矢印Ｘ方向に移動するように構成してある。ロータＲは、ハウジングＨｒに組み付けられた状態でロータ保持手段２によって保持される。このため、ロータ保持手段２はハウジングＨｒの凹部にピンを係合させて位置決めをする手段（図示せず）を備えている。   In the figure, reference numeral 1 denotes a base on which a rotor holding means 2 is installed. The rotor holding means 2 is configured such that one end of the shaft portion of the rotor R is gripped by the chuck mechanism 2a and is guided in a linear guide (not shown) as a support means to move in the direction of arrow X in the figure. The rotor R is held by the rotor holding means 2 in a state assembled to the housing Hr. For this reason, the rotor holding means 2 includes means (not shown) for positioning by engaging a pin with the recess of the housing Hr.

ロータ保持手段２はカム係合手段３を備えている。カム係合手段３は、ロータ保持手段２の本体部２ｂに固設したスリーブ部材４と、スリーブ部材４に上下動自在に支持したロッド部材５と、ロッド部材５の下端に設けたローラ部材６と、ロッド部材５を下方へ付勢するスプリング部材７とで構成してある。なお、ロータ保持手段２を図１の待機位置まで後退させると、その本体部２ｂがストッパーボルト８に当接する一方、ローラ部材６が基台１上の係止部材９の後方側傾斜面９ａに乗り上げて、ロータ保持手段２がこの位置に保持されることになる。   The rotor holding means 2 is provided with cam engaging means 3. The cam engaging means 3 includes a sleeve member 4 fixed to the main body 2b of the rotor holding means 2, a rod member 5 supported on the sleeve member 4 so as to be movable up and down, and a roller member 6 provided at the lower end of the rod member 5. And a spring member 7 for urging the rod member 5 downward. When the rotor holding means 2 is retracted to the standby position in FIG. 1, the main body 2 b comes into contact with the stopper bolt 8, while the roller member 6 contacts the rear inclined surface 9 a of the locking member 9 on the base 1. As a result, the rotor holding means 2 is held in this position.

基台１の上面には、図１に示す位置にスタータＳを保持するステータ保持手段（図示せず）を設置してある。スタータＳは、ハウジングＨｓに組み付けられた状態でこの保持手段に保持される。   Stator holding means (not shown) for holding the starter S is installed on the upper surface of the base 1 at the position shown in FIG. The starter S is held by the holding means in a state assembled to the housing Hs.

基台１の上面には、カム手段としてのカム部材１０を固設してある。このカム部材１０は、その後端面に形成した急斜面（急峻部）１０ａと、急斜面１０ａの上端に連なる前上がりの緩斜面１０ｂと、傾斜面１０ｂの前端に連なる水平面１０ｃとを形成してある。このうち、急斜面１０ａは、ロータＲがその端縁をステータＳの端縁と一致させる位置まで移動した際、カム係合手段３のローラ部材６がこれと係合するように配置されている。また、ロータＲがステータＳ内に完全に挿入されると、ロータ保持手段２の本体部２ｂがストッパーボルト１１に当接して、ロータ保持手段２の前進が阻止されることになる。   A cam member 10 as a cam means is fixed on the upper surface of the base 1. The cam member 10 is formed with a steep slope (steep portion) 10a formed on the rear end face thereof, a front rising gentle slope 10b continuous with the upper end of the steep slope 10a, and a horizontal plane 10c continuous with the front end of the inclined face 10b. Among these, the steep slope 10a is arranged so that the roller member 6 of the cam engaging means 3 engages with the rotor R when the rotor R moves to a position where the end edge thereof coincides with the end edge of the stator S. Further, when the rotor R is completely inserted into the stator S, the main body 2b of the rotor holding means 2 comes into contact with the stopper bolt 11 and the forward movement of the rotor holding means 2 is prevented.

次に、このロータ組付装置の動作について説明する。   Next, the operation of this rotor assembly apparatus will be described.

予め、スタータＳをハウジングＨｓに組み付けてステータ保持手段に保持する一方、ロータＲをハウジングＨｒに組み付け、これを待機位置にあるロータ保持手段２に保持させておく。ここで、作業者がロータ保持手段２を押してステータ保持手段側に前進させると、カム係合手段３のローラ部材６が係止部材９から降りて基台１上を転動する。そして、図１の二点鎖線で示すように、ロータＲがその端縁をステータＳの端縁と一致する位置まで移動すると、ロータＲのステータＳに対する吸引力Ｆが最大になる（図２(ａ)参照）。一方、この位置ａでカム係合手段３のローラ部材６が急斜面１０ａに係合するため、吸引力Ｆに対する対抗力ｆも最大になるが（同図(ｂ)参照）、対抗力ｆの方が勝っているため、ロータ保持手段２はこの位置ａで停止する。   In advance, the starter S is assembled to the housing Hs and held by the stator holding means, while the rotor R is assembled to the housing Hr and held by the rotor holding means 2 at the standby position. Here, when the operator pushes the rotor holding means 2 and advances it to the stator holding means side, the roller member 6 of the cam engaging means 3 descends from the locking member 9 and rolls on the base 1. Then, as shown by a two-dot chain line in FIG. 1, when the rotor R moves to a position where the end edge thereof coincides with the end edge of the stator S, the attractive force F of the rotor R with respect to the stator S is maximized (FIG. 2 ( a)). On the other hand, since the roller member 6 of the cam engaging means 3 is engaged with the steep slope 10a at this position a, the counter force f against the suction force F is maximized (see FIG. 5B). Therefore, the rotor holding means 2 stops at this position a.

ここで、作業者がロータ保持手段２を押すと、ローラ部材６が急斜面１０ａを乗り越えて緩斜面１０ｂに移る。その際、同図(ｂ)に示すように、対抗力ｆの増加が急激になるのは、ローラ部材６に対する摩擦が静止摩擦から動摩擦に変化するためである。緩斜面１０ｂ上をローラ部材６が転動する際の対抗力ｆは、ローラ部材６の摩擦力によるものであるため、ローラ部材６が急斜面１０ａ上を転動する場合に較べて小さくなる（同図(ｂ)参照）。   Here, when the operator pushes the rotor holding means 2, the roller member 6 gets over the steep slope 10a and moves to the gentle slope 10b. At that time, as shown in FIG. 5B, the increase in the counter force f is rapid because the friction with respect to the roller member 6 changes from static friction to dynamic friction. The counter force f when the roller member 6 rolls on the gentle slope 10b is due to the frictional force of the roller member 6, and therefore becomes smaller than when the roller member 6 rolls on the steep slope 10a (same as above). (Refer figure (b)).

ロータＲがステータＳ内に侵入して行くにしたがって、吸引力Ｆが急激に減少するため（同図(ａ)参照）、ロータ保持手段２を軽く押すことで、ローラ部材６を緩斜面１０ｂ上で転動させることができる。そして、ローラ部材６が緩斜面１０ｂから水平面１０ｃに移ると、対抗力ｆがさらに小さくなる。やがて、ロータ保持手段２の本体部２ｂがストッパーボルト１１に当接し、ロータＲがステータＳ内に完全に挿入されることになる。   As the rotor R enters the stator S, the suction force F decreases abruptly (see FIG. 5A), so that the roller member 6 is moved on the gentle slope 10b by lightly pushing the rotor holding means 2. Can be rolled. And if the roller member 6 moves to the horizontal surface 10c from the gentle slope 10b, the opposing force f will become still smaller. Eventually, the main body 2b of the rotor holding means 2 comes into contact with the stopper bolt 11, and the rotor R is completely inserted into the stator S.

このようにロータ保持手段２を軽く押すことで、ロータＲがステータＳ内に緩やかに挿入されていくので、ロータ側ハウジングＨｒのシール材Ｏの噛み込みを防止することができる。   Since the rotor R is gently inserted into the stator S by lightly pressing the rotor holding means 2 in this manner, the sealing material O of the rotor side housing Hr can be prevented from being caught.

このロータ組付装置によれば、油圧シリンダやボールねじ等の駆動手段を用いなくても、ロータのステータ対する挿入が緩やかに行われるので、作業時間の短縮による作業能率の向上を図ることができる。   According to this rotor assembling apparatus, since the rotor is inserted into the stator gently without using a driving means such as a hydraulic cylinder or a ball screw, the working efficiency can be improved by shortening the working time. .

なお、以上の実施形態では、ロータ保持手段２を移動させてロータＲをステータＳ内に挿入しているが、ステータ保持手段を移動させるようにしてもよい。   In the above embodiment, the rotor holding means 2 is moved and the rotor R is inserted into the stator S. However, the stator holding means may be moved.
