Description

本発明は、圧入装置に関する。   The present invention relates to a press-fitting device.

特許文献１には、環状の被圧入部材を軸部材に圧入する圧入装置が開示されている。   Patent Document 1 discloses a press-fitting device that press-fits an annular press-fitted member into a shaft member.

特開２００８−１７３７４２号公報JP 2008-173742 A

この圧入装置は、環状の被圧入部材を軸部材に圧入する圧入ヘッドと、軸部材を支持する支持台とを備えており、圧入ヘッドは、支持台で支持された軸部材の中心線上で、支持台に対して相対移動可能に設けられている。
ここで、軸部材には、当該軸部材の中心線に沿う位置決め孔が形成されており、圧入ヘッドには、被圧入部材を圧入する際に位置決め孔に挿入されるセンタリングピンが一体に形成されている。 The press-fitting device includes a press-fitting head that press-fits an annular press-fitted member into a shaft member, and a support base that supports the shaft member, and the press-fitting head is on the center line of the shaft member supported by the support base. It is provided so as to be movable relative to the support base.
Here, the shaft member is formed with a positioning hole along the center line of the shaft member, and the press-fitting head is integrally formed with a centering pin that is inserted into the positioning hole when the press-fitted member is press-fitted. ing.

この圧入装置では、圧入ヘッドを支持台側に移動させると、圧入ヘッドのセンタリングピンが軸部材の位置決め孔に挿入されて、中心線の径方向における圧入ヘッドと軸部材との位置決めがされたのち、被圧入部材が、圧入ヘッドにより押されて、軸部材の外周に圧入されるようになっている。   In this press-fitting device, when the press-fitting head is moved to the support base side, the centering pin of the press-fitting head is inserted into the positioning hole of the shaft member, and the press-fitting head and the shaft member are positioned in the radial direction of the center line. The press-fitted member is pressed by the press-fitting head and is press-fitted onto the outer periphery of the shaft member.

ここで、無段変速機のプーリシャフトのように、外径の異なる部位が長手方向に複数連なった軸部材の場合、内径の異なる複数の被圧入部材が、それぞれ対応する外径の部位に圧入されることになる。
また、被圧入部材の径が異なる複数種の機種を同じ設備で組立てる場合もある。
そのため、圧入装置では、内径の異なる被圧入部材毎に、専用の圧入ヘッドを複数軸用意しておき、圧入する被圧入部材の径に応じて圧入ヘッドを切替えながら、すべての被圧入部材の軸部材への圧入を行うようになっている。 Here, in the case of a shaft member in which a plurality of portions having different outer diameters are connected in the longitudinal direction, such as a pulley shaft of a continuously variable transmission, a plurality of press-fitting members having different inner diameters are press-fitted into corresponding outer diameter portions. Will be.
In addition, a plurality of types of models with different press-fitting member diameters may be assembled with the same equipment.
Therefore, in the press-fitting device, a plurality of dedicated press-fitting heads are prepared for each press-fitting member having a different inner diameter, and the shafts of all the press-fitting members are switched while switching the press-fitting head according to the diameter of the press-fitting member to be press-fitted. It press-fits to a member.

しかし、径の異なる被圧入部材毎に専用の圧入ヘッドを複数軸用意することは設備コストが上昇してしまう。また、専用の圧入ヘッドを複数軸用意するのではなく、圧入ヘッドの先端を、径の異なる被圧入部材毎に切り替えをする（段取り替えをする）ことも考えられるが、圧入ヘッドの先端が高重量である場合には、作業者の負担が大きく、切り替えをすることが困難であると共に、切り替えの作業が繁雑となってしまう。   However, preparing a plurality of dedicated press-fitting heads for each press-fitting member having a different diameter increases the equipment cost. Also, instead of preparing multiple dedicated press-fitting heads, it is conceivable to switch the tip of the press-fitting head for each press-fitting member with a different diameter (change the setup). If the weight is used, the burden on the operator is great, and it is difficult to switch, and the switching work becomes complicated.

そのため、より簡単に、圧入ヘッドの切り替えを行えるようにすることが求められている。   For this reason, it is required to switch the press-fitting head more easily.

本発明によれば、圧入ヘッドを、保持台の挿通部にヘッド係合部側から挿入すると、圧入ヘッドは、係止部が挿通部の周縁に係止された位置で保持される。このように、圧入ヘッドを、ヘッド係合部に固定するのではなく保持台に保持させることによって、圧入ヘッドの切り替えをより簡単に行うことができる。   According to the present invention, when the press-fitting head is inserted into the insertion part of the holding base from the head engagement part side, the press-fitting head is held at a position where the locking part is locked to the periphery of the insertion part. In this way, the press-fitting head can be more easily switched by holding the press-fitting head on the holding base instead of fixing it to the head engaging portion.

以下、本発明の実施の形態を、軸部材が、無段変速機のプーリ３の軸部３１１、嵌合部３２２である場合を例に挙げて説明する。
図１は、実施の形態にかかる圧入装置１を説明する概略図であって、（ａ）は、支持台２で支持されたプーリ３の上方に圧入ヘッド６が配置された状態を示す図であって、圧入ヘッド６により、プランジャ３４（被圧入部材）を、プーリ３の嵌合部３２２の外周に圧入する前の状態を示す図であり、（ｂ）は、圧入ヘッド６側を分解して示す図である。 Hereinafter, the embodiment of the present invention will be described by taking as an example the case where the shaft members are the shaft portion 311 and the fitting portion 322 of the pulley 3 of the continuously variable transmission.
FIG. 1 is a schematic diagram illustrating a press-fitting device 1 according to an embodiment. FIG. 1A is a diagram illustrating a state in which a press-fitting head 6 is disposed above a pulley 3 supported by a support base 2. FIG. 6 is a view showing a state before the plunger 34 (member to be pressed) is press-fitted into the outer periphery of the fitting portion 322 of the pulley 3 by the press-fitting head 6, and FIG. FIG.

図１の（ａ）に示すように、圧入装置１は、プーリ３を支持する支持台２と、この支持台２で支持されたプーリ３の中心線Ｘ方向に進退移動するヘッド係合部４と、支持台２とヘッド係合部４の間で、中心線Ｘの軸方向に移動可能に設けられた保持台５と、保持台５で保持された圧入ヘッド６とを、備えて構成される。   As shown in FIG. 1A, the press-fitting device 1 includes a support base 2 that supports a pulley 3, and a head engagement portion 4 that moves forward and backward in the direction of the center line X of the pulley 3 supported by the support base 2. And a holding table 5 provided so as to be movable in the axial direction of the center line X between the support table 2 and the head engaging portion 4, and a press-fitting head 6 held by the holding table 5. The

支持台２の中央には、プーリ３側の上方に突出する係合突起２１が設けられている。この支持台２の係合突起２１に、プーリ３における固定円錐盤３１の軸部３１１に設けた嵌合孔３２ａが嵌合されている。
この状態においてプーリ３の固定円錐盤３１は、軸部３１１の中心線Ｘを鉛直方向に沿わせた向きで配置されており、プーリ３の上方では、保持台５で保持された圧入ヘッド６と、圧入ヘッド６を支持台２側の下方に移動させるヘッド係合部４とが、中心線Ｘ上で同軸に配置されている。 At the center of the support base 2, an engagement protrusion 21 that protrudes upward on the pulley 3 side is provided. A fitting hole 32 a provided in the shaft portion 311 of the fixed conical disk 31 in the pulley 3 is fitted into the engaging protrusion 21 of the support base 2.
In this state, the fixed conical disk 31 of the pulley 3 is arranged with the center line X of the shaft portion 311 along the vertical direction. Above the pulley 3, the press-fitting head 6 held by the holding table 5 and The head engaging portion 4 that moves the press-fitting head 6 downward on the support base 2 side is arranged coaxially on the center line X.

プーリ３は、固定円錐盤３１と、この固定円錐盤３１の軸部３１１に外挿された可動円錐盤３２と、を有している。可動円錐盤３２の円筒部３２１は、軸部３１１の外周にスプライン嵌合しており、可動円錐盤３２は、固定円錐盤３１との相対回転が規制された状態で、固定円錐盤３１の中心線Ｘ方向に進退移動可能に設けられている。   The pulley 3 includes a fixed conical disk 31 and a movable conical disk 32 that is externally attached to the shaft portion 311 of the fixed conical disk 31. The cylindrical portion 321 of the movable cone 32 is spline-fitted to the outer periphery of the shaft portion 311, and the movable cone 32 is in the center of the fixed cone 31 in a state where relative rotation with the fixed cone 31 is restricted. It is provided so as to be able to move forward and backward in the direction of the line X.

可動円錐盤３２では、シーブ部３２０の円筒部３２１側（図１（ａ）中では上側）の面に、プランジャ３４の開口が圧入される嵌合部（突起部）３２２が設けられており、この嵌合部３２２の外周に、中心線Ｘの軸方向からプランジャ３４（被圧入部材）が嵌合され、圧入されるようになっている。
さらに、固定円錐盤３１の軸部３１１では、可動円錐盤３２の円筒部３２１から突出した先端部３１１ａの外周に、図４（ａ）〜図４（ｃ）に示すように、プランジャ３４よりも外径の小さい被圧入部材（後記するベアリング３５）が圧入されるようになっている。 In the movable conical disk 32, a fitting portion (projection portion) 322 into which the opening of the plunger 34 is press-fitted is provided on the surface of the sheave portion 320 on the cylindrical portion 321 side (the upper side in FIG. 1A). A plunger 34 (press-fitted member) is fitted to the outer periphery of the fitting portion 322 from the axial direction of the center line X and is press-fitted.
Further, in the shaft portion 311 of the fixed cone 31, the outer periphery of the tip portion 311 a protruding from the cylindrical portion 321 of the movable cone 32 is positioned more than the plunger 34, as shown in FIGS. 4 (a) to 4 (c). A press-fit member (a bearing 35 described later) having a small outer diameter is press-fitted.

このように、プーリ３には、外径の異なる被圧入部材（プランジャ３４、ベアリング３５）が圧入されるようになっており、実施の形態にかかる圧入装置１では、被圧入部材毎に用意された圧入ヘッド６、６Ａを用いて、被圧入部材の圧入を行うようになっている。   Thus, the press-fitting members (plunger 34 and bearing 35) having different outer diameters are press-fitted into the pulley 3, and the press-fitting device 1 according to the embodiment is prepared for each press-fitted member. The press-fitting member is press-fitted using the press-fitting heads 6 and 6A.

圧入ヘッド６は、円筒状の基部６１を有しており、この基部６１の外径Ｄ１は、保持台５に設けた挿通穴５１０の内径Ｄ１と整合する径で形成されている（図１の（ｂ）参照）。
この基部６１のヘッド係合部４側（図１（ａ）中では上側）の端部には、中心線Ｘの径方向に延出して係止部６２が形成されている。この係止部６２は、中心線Ｘ周りの周方向の全周に亘って設けられており、中心線Ｘの軸方向から見てリング状を成している。 The press-fitting head 6 has a cylindrical base 61, and the outer diameter D1 of the base 61 is formed with a diameter that matches the inner diameter D1 of the insertion hole 510 provided in the holding base 5 (FIG. 1). (See (b)).
At the end of the base 61 on the head engaging portion 4 side (the upper side in FIG. 1A), a locking portion 62 is formed extending in the radial direction of the center line X. The locking portion 62 is provided over the entire circumference in the circumferential direction around the center line X, and has a ring shape when viewed from the axial direction of the center line X.

基部６１の支持台２側（図１（ａ）中では下側）には、基部６１よりも外径の小さい接続部６３を介して、円筒状の押圧部６４が接続されている。この押圧部６４は、支持台２側の下方に向かうにつれて外径が小さくなる先細り形状を成しており、その先端面が、被圧入部材（プランジャ３４）を中心線Ｘの軸方向に押圧する押圧面６４ａとなっている。   A cylindrical pressing portion 64 is connected to the support base 2 side (lower side in FIG. 1A) of the base portion 61 via a connection portion 63 having an outer diameter smaller than that of the base portion 61. The pressing portion 64 has a tapered shape in which the outer diameter decreases toward the lower side of the support base 2, and the distal end surface presses the pressed member (plunger 34) in the axial direction of the center line X. It is a pressing surface 64a.

圧入ヘッド６では、後記するセンタリングピン４３を挿入可能な貫通孔６ａが、中心線Ｘの軸方向に貫通して形成されており、この貫通孔６ａは、中心線Ｘの軸方向の全長に亘って同一の内径Ｄ２で形成されている。   In the press-fitting head 6, a through hole 6 a into which a centering pin 43 to be described later can be inserted is formed so as to penetrate in the axial direction of the center line X, and this through hole 6 a extends over the entire length of the center line X in the axial direction. Are formed with the same inner diameter D2.

実施の形態では、貫通孔６ａの内径Ｄ２と、押圧部６４の先端側の外径Ｄ３と、押圧部６４の基部６１からの長さ（中心線Ｘの軸方向における基部６１と接続部６３の境界部から押圧面６４ａまでの長さ）Ｌ１の少なくとも１つが異なる複数の圧入ヘッド６が用意されており、被圧入部材の内径とほぼ整合する内径の押圧部６４を有する圧入ヘッド６を用いて、被圧入部材の圧入を行うようになっている。
そして、圧入ヘッド６は、ヘッド係合部４およびセンタリングピン４３とは別体に設けられており、保持台５において着脱自在に保持されている。これにより、被圧入部材のサイズに応じて、圧入ヘッド６を交換することができる。 In the embodiment, the inner diameter D2 of the through hole 6a, the outer diameter D3 on the distal end side of the pressing portion 64, the length from the base portion 61 of the pressing portion 64 (the base portion 61 and the connection portion 63 in the axial direction of the center line X). A plurality of press-fitting heads 6 having at least one of L1 (length from the boundary part to the pressing surface 64a) are prepared, and the press-fitting head 6 having the pressing part 64 having an inner diameter substantially matching the inner diameter of the press-fitting member is used. The press-fitting member is press-fitted.
The press-fitting head 6 is provided separately from the head engaging portion 4 and the centering pin 43, and is detachably held on the holding stand 5. Thereby, the press-fit head 6 can be replaced according to the size of the press-fit member.

圧入ヘッド６を保持する保持台５では、板状の基部５１の中央に、圧入ヘッド６の押圧部６４側を挿通させる挿通穴５１０が形成されており、この挿通穴５１０は、基部５１を厚み方向に貫通して形成されている。
基部５１のヘッド係合部４側（図１（ｂ）中では上側）の面には、挿通穴５１０に対して段差部を介して拡径部５１１が設けられており、この拡径部５１１は、圧入ヘッド６の係止部６２の外径Ｄ４と整合する内径Ｄ４で形成されている。言い換えると、拡径部５１１に対して、挿通穴５１０が小径部となる。 In the holding table 5 that holds the press-fitting head 6, an insertion hole 510 through which the pressing part 64 side of the press-fitting head 6 is inserted is formed in the center of the plate-like base 51, and the insertion hole 510 has a thickness at the base 51. It is formed to penetrate in the direction.
On the surface of the base 51 on the head engaging portion 4 side (the upper side in FIG. 1B), an enlarged diameter portion 511 is provided via a step portion with respect to the insertion hole 510, and this enlarged diameter portion 511. Is formed with an inner diameter D4 that matches the outer diameter D4 of the locking portion 62 of the press-fitting head 6. In other words, the insertion hole 510 is a small diameter portion with respect to the enlarged diameter portion 511.

そのため、圧入ヘッド６の押圧部６４側を、ヘッド係合部４側から挿通穴５１０に挿入した際に、基部６１に設けた係止部６２が拡径部５１１に係止、着座することで、圧入ヘッド６が保持台５から脱落することが阻止される。また、保持台５は、平面視ほぼＣ字状であってもよく、すなわち基部５１の外縁の端面から挿通穴５１０及び拡径部５１１に達する切欠き部を設けてもよい。この切欠き部を設けることにより、圧入ヘッド６を保持台５に挿入する際に、挿通穴５１０及び拡径部５１１が拡がるように保持台５を変形させることが可能となり、圧入ヘッド６の挿入が容易となる。   Therefore, when the pressing portion 64 side of the press-fitting head 6 is inserted into the insertion hole 510 from the head engaging portion 4 side, the locking portion 62 provided on the base portion 61 is locked and seated on the enlarged diameter portion 511. The press-fitting head 6 is prevented from falling off the holding table 5. Further, the holding base 5 may be substantially C-shaped in a plan view, that is, a notch that reaches the insertion hole 510 and the enlarged diameter portion 511 from the end surface of the outer edge of the base 51 may be provided. By providing this notch portion, when the press-fitting head 6 is inserted into the holding base 5, the holding base 5 can be deformed so that the insertion hole 510 and the enlarged diameter portion 511 are expanded, and the press-fitting head 6 can be inserted. Becomes easy.

ここで、保持台５は、図示しないガイド機構により、中心線Ｘの軸方向に移動可能に設けられていると共に、当該保持台５に接続されたエアシリンダから作用する付勢力で、ヘッド係合部４側の上方に付勢されている。なお、保持台５を付勢する付勢機構としては、エアシリンダに限定するものではなく、バネなどの弾性部材であってもよい。
そのため、保持台５およびヘッド係合部４は、当該保持台５で保持された圧入ヘッド６を、支持台２側の下方から、ヘッド係合部４の円柱状の係合部４２に当接させることが可能な位置関係で配置されており、圧入ヘッド６は、エアシリンダから作用する付勢力で、係合部４２に当接した状態で保持されるようになっている。
そのため、ヘッド係合部４が中心線Ｘの軸方向に移動する際に、圧入ヘッド６は、ヘッド係合部４と常に一体に移動するようになっている。 Here, the holding table 5 is provided so as to be movable in the axial direction of the center line X by a guide mechanism (not shown), and the head engagement is performed by an urging force acting from an air cylinder connected to the holding table 5. It is biased upward on the part 4 side. The biasing mechanism that biases the holding base 5 is not limited to the air cylinder, and may be an elastic member such as a spring.
Therefore, the holding stand 5 and the head engaging portion 4 abut the press-fitting head 6 held by the holding stand 5 on the columnar engaging portion 42 of the head engaging portion 4 from below the support stand 2 side. The press-fitting head 6 is held in contact with the engaging portion 42 by an urging force acting from the air cylinder.
For this reason, when the head engaging portion 4 moves in the axial direction of the center line X, the press-fitting head 6 always moves integrally with the head engaging portion 4.

ここで、ヘッド係合部４の係合部４２の中央には、円柱形状のセンタリングピン４３が一体に形成されている。このセンタリングピン４３は、支持台２側の下方に直線状に延びており、圧入ヘッド６により被圧入部材を圧入する際に、プーリ３の軸部３１１に設けた位置決め孔３１１ｂに挿入されて、ヘッド係合部４に係合した圧入ヘッド６の中心線Ｘの径方向の位置決めが行われるようになっている。
なお、係合部４２とセンタリングピン４３とは別体に設けてもよい。すなわち、係合部４２に対してセンタリングピン４を脱着可能に設けてもよい。これにより、プーリ３の種類が変更となり、センタリングピン４３の中心線Ｘの軸方向における長さが変更になった場合でも、ヘッド係合部４全体を交換する必要が無く、センタリングピン４３のみを交換するだけで対応可能となる。 Here, a cylindrical centering pin 43 is integrally formed at the center of the engaging portion 42 of the head engaging portion 4. The centering pin 43 extends linearly below the support base 2 side, and is inserted into a positioning hole 311b provided in the shaft portion 311 of the pulley 3 when the press-fitting member 6 is press-fitted by the press-fitting head 6. The press-fitting head 6 engaged with the head engaging portion 4 is positioned in the radial direction of the center line X.
The engaging portion 42 and the centering pin 43 may be provided separately. That is, the centering pin 4 may be detachable from the engaging portion 42. Thereby, even if the type of the pulley 3 is changed and the length in the axial direction of the center line X of the centering pin 43 is changed, it is not necessary to replace the entire head engaging portion 4 and only the centering pin 43 is changed. It can be handled simply by exchanging.

かかる構成の圧入装置１の作用を説明する。
図２は、圧入装置１によるプランジャ３４の圧入を説明する図であり、（ａ）は、プランジャ３４の圧入前の状態を示す図であり、（ｂ）は、ヘッド係合部４を支持台２側に移動させた初期状態を示す図であり、（ｃ）は、ヘッド係合部４により押された圧入ヘッド６により、プランジャ３４がプーリ３の嵌合部３２２に圧入された状態を示す図である。 The operation of the press-fitting device 1 having such a configuration will be described.
2A and 2B are views for explaining the press-fitting of the plunger 34 by the press-fitting device 1. FIG. 2A is a view showing a state before the plunger 34 is press-fitted, and FIG. It is a figure which shows the initial state moved to 2 side, (c) shows the state by which the plunger 34 was press-fit in the fitting part 322 of the pulley 3 with the press-fit head 6 pushed by the head engaging part 4.

支持台２に支持させたプーリ３の嵌合部３２２にプランジャ３４をセットしたのち、ヘッド係合部４を支持台２側の下方に移動させると、圧入ヘッド６を保持する保持台５は、中心線Ｘの軸方向に移動可能に設けられているので、ヘッド係合部４に当接した圧入ヘッド６もまた、支持台２側の下方に移動することになる（図２の（ａ）：矢印参照）。   After setting the plunger 34 to the fitting part 322 of the pulley 3 supported by the support base 2 and then moving the head engaging part 4 downward on the support base 2 side, the holding base 5 for holding the press-fitting head 6 is Since it is provided so as to be movable in the axial direction of the center line X, the press-fitting head 6 in contact with the head engaging portion 4 also moves downward on the support base 2 side ((a) in FIG. 2). : See arrow).

そうすると、ヘッド係合部４に設けたセンタリングピン４３が、プーリ３の位置決め孔３１１ｂに挿入されて、ヘッド係合部４に係合した圧入ヘッド６の中心線Ｘの径方向の位置決めが行われる（図２の（ｂ）参照）。すなわち、プーリ３と、ヘッド係合部４及び圧入ヘッド６とが調心される。   Then, the centering pin 43 provided in the head engaging portion 4 is inserted into the positioning hole 311b of the pulley 3, and the radial positioning of the center line X of the press-fitting head 6 engaged with the head engaging portion 4 is performed. (See (b) in FIG. 2). That is, the pulley 3, the head engaging portion 4, and the press-fitting head 6 are aligned.

この状態から、圧入ヘッド６が、支持台２側の下方にさらに移動すると、圧入ヘッド６の押圧部６４の押圧面６４ａが、プランジャ３４に接触して、プランジャ３４を支持台２側の下方に押圧する。
これにより、圧入ヘッド６が支持台２側の所定位置まで移動する間に、圧入ヘッド６により押されたプランジャ３４は、プーリ３の嵌合部３２２に圧入されることになる（図２の（ｃ））。 From this state, when the press-fitting head 6 further moves downward on the support base 2 side, the pressing surface 64a of the pressing portion 64 of the press-fitting head 6 contacts the plunger 34, and the plunger 34 is moved downward on the support base 2 side. Press.
Thus, while the press-fitting head 6 moves to a predetermined position on the support base 2 side, the plunger 34 pushed by the press-fitting head 6 is press-fitted into the fitting portion 322 of the pulley 3 ((( c)).

そして、圧入ヘッド６を支持台２側の所定位置まで移動させたのち、図示しない駆動機構により、ヘッド係合部４を支持台２から離れる方向（上方側）に移動させると、保持台５は、エアシリンダから作用する付勢力で上方側に付勢されているので、保持台５で保持された圧入ヘッド６は、ヘッド係合部４に係合した状態のままで、ヘッド係合部４と一体的に、上方側に移動することになる。   Then, after the press-fitting head 6 is moved to a predetermined position on the support base 2 side, the head engaging portion 4 is moved away from the support base 2 (upward side) by a drive mechanism (not shown), the holding base 5 is Since the urging force acting from the air cylinder is biased upward, the press-fitting head 6 held by the holding base 5 remains engaged with the head engaging portion 4 and the head engaging portion 4 And move upward.

次に、圧入ヘッド６の交換を説明する。
図３は、圧入ヘッド６の交換を説明する図であり、（ａ）は、保持台５が圧入ヘッド６を中心線Ｘ上に位置させる位置に配置された状態を示す斜視図であり、（ｂ）は、保持台５が圧入ヘッド６を中心線Ｘの径方向外側の圧入ヘッドの交換位置に配置した状態を示す斜視図である。 Next, replacement of the press-fitting head 6 will be described.
FIG. 3 is a view for explaining replacement of the press-fitting head 6, and FIG. 3A is a perspective view showing a state in which the holding base 5 is disposed at a position where the press-fitting head 6 is positioned on the center line X. b) is a perspective view showing a state in which the holding table 5 has the press-fitting head 6 disposed at the exchange position of the press-fitting head on the radially outer side of the center line X. FIG.

実施の形態の圧入装置１には、保持台５の基部５１を、中心線Ｘの径方向に移動させる移動機構（図示せず）を有しており、圧入ヘッド６を保持する保持台５は、中心線Ｘの軸方向（図３の（ａ）、矢印Ａ参照）だけで無く、中心線Ｘの径方向（図３の（ａ）、矢印Ｂ参照）にも移動可能となっている。
言い換えると、中心線Ｘの径方向とは、中心線Ｘと直交する平面における任意の少なくとも一方向である。また、移動機構は、基部５１を中心線Ｘと直交する平面における直交する二方向に移動させるものであってもよい。さらに、移動機構は、保持台５を中心線Ｘと平行な軸線を中心に回転させる回転機構であってもよい。
保持台５は、中心線Ｘに対して平行に配置された板状の支持部５３を有しており、保持台５の基部５１は、支持部５３の長手方向における一端側に、取付部材５２を介して取り付けられている。また、支持部５３に複数の基部５１を取り付け、それぞれの基部５１に、サイズおよび／または形状の異なる圧入ヘッド６を設けるようにしても良い。これにより、圧入ヘッド６を交換することなく、複種類の被圧入部材に対応することができる。 The press-fitting device 1 according to the embodiment has a moving mechanism (not shown) that moves the base 51 of the holding base 5 in the radial direction of the center line X, and the holding base 5 that holds the press-fitting head 6 includes In addition to the axial direction of the center line X (see FIG. 3A, arrow A), it can also move in the radial direction of the center line X (see FIG. 3A, arrow B).
In other words, the radial direction of the center line X is at least one arbitrary direction on a plane orthogonal to the center line X. The moving mechanism may move the base 51 in two orthogonal directions on a plane orthogonal to the center line X. Furthermore, the moving mechanism may be a rotating mechanism that rotates the holding table 5 about an axis parallel to the center line X.
The holding base 5 has a plate-like support portion 53 arranged in parallel to the center line X, and the base 51 of the holding base 5 is attached to one end side in the longitudinal direction of the support portion 53 at the attachment member 52. Is attached through. Further, a plurality of base portions 51 may be attached to the support portion 53, and the press-fitting heads 6 having different sizes and / or shapes may be provided on the respective base portions 51. Thereby, it is possible to cope with multiple types of press-fitting members without replacing the press-fitting head 6.

保持台５の基部５１は、中心線Ｘに対して直交する向きで水平に配置されており、基部５１で保持された圧入ヘッド６は、中心線Ｘの径方向外側の圧入ヘッド６の交換位置（図３の（ｂ）参照）と、中心線Ｘ上の被圧入部材の圧入位置（図３の（ａ）参照）との間を移動するようになっている。ここで言う中心線Ｘに対して直交する向きとは、中心線Ｘと直交する平面の延長方向である。   The base 51 of the holding base 5 is horizontally arranged in a direction orthogonal to the center line X, and the press-fitting head 6 held by the base 51 is replaced with the press-fitting head 6 that is radially outside the center line X. (See (b) of FIG. 3) and the press-fitting position of the press-fit member on the center line X (see (a) of FIG. 3). Here, the direction orthogonal to the center line X is an extension direction of a plane orthogonal to the center line X.

圧入ヘッド６を交換する際には、基部５１で保持された圧入ヘッド６は、中心線Ｘの径方向外側の圧入ヘッド６の交換位置に配置されるようになっている。
ここで、基部５１において圧入ヘッド６は、基部５１に設けた凹部５１１に係止部６２を上側から係止させて設けられているので、圧入ヘッド６を上側に移動させるだけで、圧入ヘッド６を基部５１から取り外すことができるようになっている。 When the press-fitting head 6 is replaced, the press-fitting head 6 held by the base 51 is arranged at the replacement position of the press-fitting head 6 on the radially outer side of the center line X.
Here, in the base 51, the press-fitting head 6 is provided by locking the locking part 62 from the upper side in the recess 511 provided in the base 51. Therefore, the press-fitting head 6 can be simply moved upward. Can be removed from the base 51.

そして、圧入ヘッド６が交換位置に配置された状態では、基部５１の上側にヘッド係合部４が位置していないので、基部５１から上方側に移動させた圧入ヘッド６がヘッド係合部４に干渉して、圧入ヘッド６の交換作業が阻害されないようになっている。   In the state where the press-fitting head 6 is disposed at the replacement position, the head engaging part 4 is not located above the base 51, so that the press-fitting head 6 moved upward from the base 51 is the head engaging part 4. Thus, the replacement work of the press-fitting head 6 is not hindered.

続いて、プランジャ３４の圧入に続いて実施されるベアリング３５の圧入を説明する。
図４は、圧入装置１によるベアリング３５の圧入を説明する図であり、（ａ）は、ベアリング３５の圧入前の状態を示す図であり、（ｂ）は、ヘッド係合部４を支持台２側に移動させた初期状態を示す図であり、（ｃ）は、ヘッド係合部４により押された圧入ヘッド６Ａにより、ベアリング３５が可動円錐盤３２の円筒部３２１から突出した先端部３１１ａの外周に、ベアリング３５が圧入された状態を示す図である。 Subsequently, the press-fitting of the bearing 35 performed following the press-fitting of the plunger 34 will be described.
4A and 4B are diagrams for explaining the press-fitting of the bearing 35 by the press-fitting device 1, FIG. 4A is a diagram illustrating a state before the bearing 35 is press-fitted, and FIG. FIG. 8C is a diagram illustrating an initial state of moving to the second side, and FIG. 8C illustrates a tip portion 311a in which the bearing 35 protrudes from the cylindrical portion 321 of the movable conical disc 32 by the press-fitting head 6A pushed by the head engaging portion 4. It is a figure which shows the state by which the bearing 35 was press-fitted in the outer periphery.

ベアリング３５の圧入に用いられる圧入ヘッド６Ａは、貫通孔６ａの内径Ｄ２’と、押圧部６４Ａの先端側の外径Ｄ３’と、押圧部６４Ａの基部６１からの長さＬ１’が、前記した圧入ヘッド６と異なっている。   The press-fitting head 6A used for press-fitting the bearing 35 has the inner diameter D2 ′ of the through hole 6a, the outer diameter D3 ′ on the distal end side of the pressing part 64A, and the length L1 ′ from the base 61 of the pressing part 64A. Different from the press-fitting head 6.

圧入ヘッド６Ａを保持台５に保持させたのち、ベアリング３５を、可動円錐盤３２の円筒部３２１から突出した先端部３１１ａの外周にセットする（図４の（ａ）参照）。
この状態から、ヘッド係合部４を支持台２側の下方に移動させると、ヘッド係合部４に係合した圧入ヘッド６Ａもまた、支持台２側の下方に移動して、ヘッド係合部４に設けたセンタリングピン４３が、プーリ３の位置決め孔３１１ｂに挿入されて、ヘッド係合部４に係合した圧入ヘッド６Ａの中心線Ｘの径方向の位置決めが行われる（図４の（ｂ）参照）。 After the press-fitting head 6A is held on the holding base 5, the bearing 35 is set on the outer periphery of the tip portion 311a protruding from the cylindrical portion 321 of the movable conical disc 32 (see FIG. 4A).
When the head engaging portion 4 is moved downward on the support base 2 side from this state, the press-fitting head 6A engaged with the head engaging portion 4 is also moved downward on the support base 2 side to The centering pin 43 provided in the portion 4 is inserted into the positioning hole 311b of the pulley 3, and the radial positioning of the center line X of the press-fitting head 6A engaged with the head engaging portion 4 is performed ((( b)).

この状態から、圧入ヘッド６Ａが、支持台２側の下方にさらに移動すると、圧入ヘッド６Ａの押圧部６４Ａの押圧面６４ａが、ベアリング３５に当接されると共に、ベアリング３５を支持台２側の下方に押圧する。
これにより、圧入ヘッド６Ａが支持台２側の所定位置まで移動する間に、圧入ヘッド６Ａにより押されたベアリング３５は、軸部３１１の先端部３１１ａの外周に圧入されることになる（図４の（ｃ））。 From this state, when the press-fitting head 6A further moves downward on the support base 2 side, the pressing surface 64a of the pressing portion 64A of the press-fitting head 6A comes into contact with the bearing 35, and the bearing 35 is moved to the support base 2 side. Press down.
As a result, while the press-fitting head 6A moves to a predetermined position on the support base 2 side, the bearing 35 pushed by the press-fitting head 6A is press-fitted into the outer periphery of the tip 311a of the shaft 311 (FIG. 4). (C)).

このように、圧入ヘッド６、６Ａは、係止部６２を、保持台５の基部５１に設けた挿通穴５１０の周縁に係止させているだけなので、圧入ヘッド６、６Ａをヘッド係合部４側に移動させることで、圧入ヘッド６、６Ａを保持台５から外すことができる。
よって、圧入ヘッド６、６Ａの配置にボルトなどを用いていないので、圧入ヘッド６、６Ａの切り替えを、より簡単に行うことができる。 In this way, the press-fitting heads 6 and 6A are merely locking the locking part 62 to the peripheral edge of the insertion hole 510 provided in the base 51 of the holding base 5, so that the press-fitting heads 6 and 6A are head engaging parts. The press-fitting heads 6, 6 </ b> A can be removed from the holding table 5 by moving to the side 4.
Therefore, since the bolts or the like are not used for the arrangement of the press-fitting heads 6 and 6A, the press-fitting heads 6 and 6A can be switched more easily.

以上の通り、実施の形態では、
（１）支持台２（支持部材）で支持されたプーリ３の中心線Ｘ方向（軸線方向）に移動する圧入ヘッド６、６Ａにより、被圧入部材（プランジャ３４、ベアリング３５）を押圧して、軸部材（可動円錐盤３２の嵌合部３２２、固定円錐盤３１の軸部３１１の先端部３１１ａ）に圧入させる圧入装置１であって、
中心線Ｘの軸方向に進退移動するヘッド係合部４と、
支持台２とヘッド係合部４の間で、中心線Ｘの軸方向に進退移動可能に設けられると共に、圧入ヘッド６、６Ａを保持する保持台５と、を備え、
保持台５に、圧入ヘッド６、６Ａの押圧部６４、６４Ａを挿通可能な挿通穴５１０を設けると共に、圧入ヘッド６、６Ａに、挿通穴５１０の周縁に係止させる係止部６２を設けて、
圧入ヘッド６、６Ａは、係止部６２をヘッド係合部４側から挿通穴５１０の周縁（拡径部５１１）に係止させて保持台５に保持させた構成とした。 As described above, in the embodiment,
(1) The press-fit member (plunger 34, bearing 35) is pressed by the press-fit heads 6 and 6A moving in the center line X direction (axial direction) of the pulley 3 supported by the support base 2 (support member), A press-fitting device 1 for press-fitting into a shaft member (a fitting part 322 of a movable conical disk 32, a tip part 311a of a shaft part 311 of a fixed conical disk 31),
A head engaging portion 4 that moves forward and backward in the axial direction of the center line X;
A support table 5 provided between the support table 2 and the head engaging portion 4 so as to be movable back and forth in the axial direction of the center line X, and holding the press-fitting heads 6 and 6A;
The holding base 5 is provided with an insertion hole 510 into which the pressing portions 64 and 64A of the press-fitting heads 6 and 6A can be inserted, and a locking part 62 for locking the press-fitting heads 6 and 6A to the periphery of the insertion hole 510 is provided. ,
The press-fitting heads 6, 6 </ b> A have a configuration in which the locking portion 62 is locked from the head engaging portion 4 side to the peripheral edge (the enlarged diameter portion 511) of the insertion hole 510 and held on the holding base 5.

圧入ヘッド６、６Ａの押圧部６４、６４Ａを、保持台５の挿通穴５１０にヘッド係合部４側から挿入すると、圧入ヘッド６、６Ａは、係止部６２が挿通穴５１０の周縁に係止された位置で保持される。このように、圧入ヘッド６、６Ａを、ヘッド係合部４に保持させるのではなく保持台５に保持させることによって、圧入ヘッド６、６Ａの切り替えをより簡単に行うことができる。
また、本実施例においては、圧入ヘッド６、６Ａは、自重により係止部６２を挿通穴５１０の周縁に係止させた例を示しており、この場合、圧入ヘッド６、６Ａは、ボルトなどを用いずに保持され、さらに、圧入ヘッド６、６Ａは、係止部６２を挿通穴５１０の周縁に係止させているだけなので、圧入ヘッド６、６Ａをヘッド係合部４側に移動させることで、圧入ヘッド６、６Ａを保持台５から外すことができ、圧入ヘッド６、６Ａの切り替えを簡単に行うことができる。
なお、圧入ヘッド６、６Ａを保持台５に対してボルト等を用いて固定する構造であってもよい。 When the pressing portions 64 and 64A of the press-fitting heads 6 and 6A are inserted into the insertion holes 510 of the holding base 5 from the head engagement portion 4 side, the press-fitting heads 6 and 6A are engaged with the peripheral portions of the insertion holes 510. Hold in the stopped position. As described above, the press-fitting heads 6 and 6A can be switched more easily by holding the press-fitting heads 6 and 6A on the holding base 5 instead of being held by the head engaging portion 4.
In this embodiment, the press-fitting heads 6 and 6A show an example in which the locking part 62 is locked to the periphery of the insertion hole 510 by its own weight. In this case, the press-fitting heads 6 and 6A are bolts or the like. Furthermore, since the press-fitting heads 6 and 6A only hold the locking part 62 on the periphery of the insertion hole 510, the press-fitting heads 6 and 6A are moved to the head engaging part 4 side. Thus, the press-fitting heads 6 and 6A can be removed from the holding table 5, and the press-fitting heads 6 and 6A can be easily switched.
The press-fitting heads 6 and 6A may be fixed to the holding table 5 using bolts or the like.

（２）ヘッド係合部４は、被圧入部材（プランジャ３４、ベアリング３５）を、軸部材（可動円錐盤３２の嵌合部３２２、固定円錐盤３１の軸部３１１の先端部３１１ａ）に圧入する際に、プーリ３の位置決め孔３１１ｂに挿入されるセンタリングピン４３を備えており、
圧入ヘッド６、６Ａには、センタリングピン４３を貫通させる貫通孔６ａが、中心線Ｘ方向に貫通して形成されている構成とした。 (2) The head engaging portion 4 press-fits the press-fit member (plunger 34, bearing 35) into the shaft member (the fitting portion 322 of the movable conical disc 32, the tip portion 311a of the shaft portion 311 of the fixed conical disc 31). A centering pin 43 to be inserted into the positioning hole 311b of the pulley 3,
The press-fitting heads 6, 6 </ b> A have a configuration in which a through hole 6 a that penetrates the centering pin 43 is formed to penetrate in the center line X direction.

このように構成すると、従来、圧入ヘッドと一体に形成されていたセンタリングピンを、ヘッド係合部に設けることで、交換頻度の高い圧入ヘッドの重量を減らすことができる。圧入ヘッドの重量が大きいと、圧入ヘッドの交換時の作業者の負担が大きくなるが、圧入ヘッドの重量が減ることで、その分だけ、作業者の負担が軽減される。   If comprised in this way, the centering pin conventionally formed integrally with the press-fit head can be provided in the head engaging portion, thereby reducing the weight of the press-fit head that is frequently replaced. If the weight of the press-fitting head is large, the burden on the operator when replacing the press-fitting head is increased, but the burden on the operator is reduced by that amount by reducing the weight of the press-fitting head.

（３）保持台５を、ヘッド係合部４側に付勢するエアシリンダ（付勢手段）をさらに備え、
保持台５は、エアシリンダから作用する付勢力で、圧入ヘッド６、６Ａを、ヘッド係合部４に支持台２側から係合させた位置に配置させる構成とした。 (3) An air cylinder (urging means) for urging the holding base 5 toward the head engaging portion 4 side is further provided.
The holding table 5 has a configuration in which the press-fitting heads 6 and 6A are arranged at positions where the head engaging portions 4 are engaged from the support table 2 side by an urging force acting from the air cylinder.

圧入ヘッド６、６Ａを、ヘッド係合部４から離間した位置に配置すると、被圧入部材（プランジャ３４、ベアリング３５）の圧入を行う際に、支持台２側に移動したヘッド係合部４が圧入ヘッド６、６Ａと係合することになる。そうすると、係合に起因する衝突音の発生や、係合時の衝撃に起因する圧入ヘッド６、６Ａとヘッド係合部４の耐久性の低下が、懸念される。
上記のように構成して、圧入ヘッド６、６Ａを、ヘッド係合部４に予め係合させておくことで、支持台２側に移動したヘッド係合部４が圧入ヘッド６、６Ａに係合することが無いので、衝突音の発生や、圧入ヘッド６、６Ａとヘッド係合部４の耐久性の低下を好適に防止できる。 When the press-fitting heads 6 and 6A are arranged at positions separated from the head engaging part 4, the head engaging part 4 moved to the support base 2 side when the press-fitted member (plunger 34, bearing 35) is press-fitted. The press-fitting heads 6 and 6A are engaged. If it does so, generation | occurrence | production of the collision sound resulting from engagement and the fall of durability of the press-fit heads 6 and 6A and the head engaging part 4 resulting from the impact at the time of engagement are anxious.
With the above-described configuration, the press-fitting heads 6 and 6A are pre-engaged with the head engaging part 4, so that the head engaging part 4 moved to the support base 2 side is engaged with the press-fitting heads 6 and 6A. Since there is no match, it is possible to suitably prevent the occurrence of a collision sound and a decrease in durability of the press-fitting heads 6 and 6A and the head engaging portion 4.

（４）保持台５を中心線Ｘの直交方向に移動させる移動機構を備えており、保持台５に保持された圧入ヘッド６、６Ａは、圧入ヘッド６、６Ａの交換時に、移動機構により、圧入ヘッド６、６Ａを中心線Ｘ上の位置から中心線Ｘの径方向外側の位置まで移動する構成とした。ここで言う中心線Ｘの直交方向とは、中心線Ｘと直交する平面における任意の少なくとも一方向である。 (4) A moving mechanism for moving the holding table 5 in the direction orthogonal to the center line X is provided, and the press-fitting heads 6 and 6A held by the holding table 5 are moved by the moving mechanism when the press-fitting heads 6 and 6A are replaced. The press-fitting heads 6 and 6A are configured to move from a position on the center line X to a position radially outside the center line X. The orthogonal direction of the center line X mentioned here is at least one arbitrary direction on a plane orthogonal to the center line X.

このように構成すると、圧入ヘッド６、６Ａの交換時に、圧入ヘッド６、６Ａとヘッド係合部４とが、中心線Ｘの径方向にオフセットした位置に配置されるので、保持台５から圧入ヘッド６、６Ａを取り外す際に、ヘッド係合部４側に移動させた圧入ヘッド６、６Ａが、ヘッド係合部４に干渉して、圧入ヘッド６、６Ａの交換が阻害されることを好適に防止できる。
さらに、ヘッド係合部４側に移動させた圧入ヘッド６、６Ａとヘッド係合部４との干渉を避けるために、支持台２とヘッド係合部４の中心線Ｘの軸方向の離間距離を広げる必要が無いので、圧入装置１の中心線Ｘの軸方向への大型化を好適に防止できる。 With this configuration, when the press-fitting heads 6 and 6A are replaced, the press-fitting heads 6 and 6A and the head engaging portion 4 are disposed at positions offset in the radial direction of the center line X. It is preferable that when the heads 6 and 6A are removed, the press-fitting heads 6 and 6A moved to the head engaging part 4 side interfere with the head engaging part 4 and the replacement of the press-fitting heads 6 and 6A is hindered. Can be prevented.
Further, in order to avoid interference between the press-fitting heads 6, 6 </ b> A moved to the head engaging portion 4 side and the head engaging portion 4, the axial distance between the support base 2 and the center line X of the head engaging portion 4. Therefore, it is possible to suitably prevent an increase in the size of the center line X of the press-fitting device 1 in the axial direction.

（５）圧入ヘッド６、６Ａでは、保持台５の基部５１に設けた挿通穴５１０の内径Ｄ１に整合する外径の基部６１の外周に係止部６２が設けられていると共に、
被圧入部材（プランジャ３４、ベアリング３５）を軸部材（可動円錐盤３２の嵌合部３２２、固定円錐盤３１の軸部３１１の先端部３１１ａ）に圧入する際に、被圧入部材を押圧する筒状の押圧部６４、６４Ａが、基部６１の支持台２側に一体に設けられており、
圧入装置１に用いられる圧入ヘッド６、６Ａは、複数用意されており、
圧入ヘッドの各々は
基部６１と係止部６２とを共通に有すると共に、
押圧部６４、６４Ａに設けた貫通穴６ａの内径Ｄ２、Ｄ２’と、押圧部６４、６４Ａの先端側の外径Ｄ３、Ｄ３’と、押圧部６４、６４Ａの基部６１からの長さＬ１、Ｌ１’が、異なる径で形成されている構成とした。 (5) In the press-fitting heads 6 and 6A, a locking portion 62 is provided on the outer circumference of the outer diameter base 61 that matches the inner diameter D1 of the insertion hole 510 provided in the base 51 of the holding base 5.
A cylinder that presses the press-fit member when the press-fit member (plunger 34, bearing 35) is press-fitted into the shaft member (the fitting portion 322 of the movable conical disc 32, the tip 311a of the shaft portion 311 of the fixed conical disc 31). Shaped pressing portions 64, 64A are integrally provided on the support base 2 side of the base portion 61,
A plurality of press-fitting heads 6 and 6A used in the press-fitting device 1 are prepared.
Each of the press-fitting heads has a base 61 and a locking portion 62 in common,
Inner diameters D2 and D2 ′ of the through holes 6a provided in the pressing portions 64 and 64A, outer diameters D3 and D3 ′ on the front end side of the pressing portions 64 and 64A, and a length L1 from the base 61 of the pressing portions 64 and 64A, L1 ′ is configured to have a different diameter.

このように構成すると、被圧入部材（プランジャ３４、ベアリング３５）の外径と整合する内径の貫通穴６ａを備える押圧部６４を有する圧入ヘッド６を選択して、保持台５に保持させるだけで、被圧入部材の圧入を適切に行うことが可能となる。
よって、異なる径の複数の被圧入部材の圧入のために、圧入装置を複数用意する必要が無いので、作製コストの上昇を好適に防止できる。 If comprised in this way, the press injection head 6 which has the press part 64 provided with the through-hole 6a of the internal diameter matched with the outer diameter of a to-be-pressed member (plunger 34, the bearing 35) will be selected, and it will be hold | maintained only to the holding stand 5. Thus, it is possible to appropriately press-fit the pressed member.
Therefore, since it is not necessary to prepare a plurality of press-fitting devices for press-fitting a plurality of press-fitting members having different diameters, an increase in manufacturing cost can be suitably prevented.

（６）保持台５の基台５１には、圧入ヘッド６、６Ａの基部６１の外径Ｄ１と整合する内径の挿通穴５１０が設けられており、押圧部６４、６４Ａの形状（例えば、押圧部６４、６４Ａの先端側の外径Ｄ３、Ｄ３’、押圧部６４Ａの基部６１からの長さＬ１、Ｌ１’、断面形状など）が異なる複数種類の圧入ヘッド６、６Ａは、基台５１において共通して保持できるようになっており、保持台５を中心線Ｘの直交方向に移動させる移動機構は、保持台５に設けた基台５１を、中心線Ｘの直交方向に移動させて、基台に保持された圧入ヘッド６、６Ａを、中心線Ｘ上の被圧入部材の圧入位置（図３の（ａ）参照）まで移動させる構成した。 (6) The base 51 of the holding base 5 is provided with an insertion hole 510 having an inner diameter that matches the outer diameter D1 of the base 61 of the press-fitting heads 6 and 6A, and the shape of the pressing parts 64 and 64A (for example, pressing A plurality of types of press-fitting heads 6 and 6A having different outer diameters D3 and D3 ′ on the distal end side of the portions 64 and 64A, lengths L1 and L1 ′ from the base portion 61 of the pressing portion 64A, cross-sectional shapes, and the like) The movement mechanism for moving the holding table 5 in the direction orthogonal to the center line X moves the base 51 provided on the holding table 5 in the direction orthogonal to the center line X.
