Here, FIG. 1 is a cross-sectional view of a main part of a press-fitting device (before press-fitting) according to the present invention, a cross-sectional view of a main part of FIG. 2 (before and after press-fitting an upper press-fitting member), and the same as FIG. 4 is a hydraulic circuit diagram of the pressure adjusting means, and FIG. 5 is a flowchart showing a work procedure of the press-fitting method.
本発明に係る圧入装置は、図１乃至図３に示すように、ほぼ水平に配置された基台１と、基台１の上方に配置されて昇降可能なスライドベース２を備えている。基台１は下部プレート３に固定され、スライドベース２は、シリンダ（不図示）により所定のストロークで昇降駆動される上部プレート４に固定されている。なお、５はシリンダロッド、６は支柱、７はガイドである。 As shown in FIGS. 1 to 3, the press-fitting device according to the present invention includes a base 1 that is disposed substantially horizontally, and a slide base 2 that is disposed above the base 1 and can be moved up and down. The base 1 is fixed to a lower plate 3, and the slide base 2 is fixed to an upper plate 4 that is driven up and down with a predetermined stroke by a cylinder (not shown). In addition, 5 is a cylinder rod, 6 is a support | pillar, 7 is a guide.
基台１には、被圧入部材（ミッションケース）Ｗを位置決めセットする中間プレート１０と、下方から圧入する圧入部材（ベアリング）Ｐ１を嵌装してセットする第１圧入パンチ１１と、被圧入部材Ｗを下方から押さえる第２押圧部材１２を固定している。 An intermediate plate 10 for positioning and setting a press-fit member (mission case) W, a press-fit member (bearing) P1 for press-fitting from below, and a first press-fitting punch 11 that is set by being fitted to the base 1, a press-fit member A second pressing member 12 that holds W from below is fixed.
中間プレート１０は、一対のガイドポスト１３を介して基台１に取り付けられ、ポール１４に巻装した弾性部材１５により上方に付勢されている。そして、圧入前において、中間プレート１０は、図１に示すように、被圧入部材Ｗを位置決めセットできる位置（原位置）にある。 The intermediate plate 10 is attached to the base 1 via a pair of guide posts 13 and is urged upward by an elastic member 15 wound around a pole 14. Before the press-fitting, the intermediate plate 10 is at a position (original position) where the press-fitting member W can be positioned and set, as shown in FIG.
また、スライドベース２には、上方から圧入する圧入部材Ｐ２を嵌装してセットする第２圧入パンチ１６と、被圧入部材Ｗを上方から所定の圧力で押圧する第１押圧部材１７と、第１押圧部材１７の押圧力を所定の圧力以下に保持する圧力調整手段１８を設けている。そして、第２圧入パンチ１６は第２押圧部材１２と対向して設置され、第１押圧部材１７は第１圧入パンチ１１と対向して設置されている。 The slide base 2 is fitted with a press-fitting member P2 that is press-fitted from above, a first press-fitting punch 16 that presses the press-fitting member W from above with a predetermined pressure, A pressure adjusting means 18 for holding the pressing force of the pressing member 17 below a predetermined pressure is provided. The second press-fitting punch 16 is installed facing the second pressing member 12, and the first pressing member 17 is installed facing the first press-fitting punch 11.
圧力調整手段１８は、図４にも示すように、第１押圧部材１７を昇降させるシリンダ２０と、シリンダ２０内の圧力が設定圧を超えると作動するリリーフバルブ２１と、シリンダ２０に所定圧の油圧を供給するタンク２２と、油の流れ方向を規制する２つのチェックバルブ２３，２４からなる。シリンダ２０は、弾性部材２０ａにより油圧の有無に拘らず、常に突出方向に付勢されている。また、タンク２２は、弾性部材２２ａにより所定圧の油圧をシリンダ２０に供給する。 As shown in FIG. 4, the pressure adjusting means 18 includes a cylinder 20 that raises and lowers the first pressing member 17, a relief valve 21 that operates when the pressure in the cylinder 20 exceeds a set pressure, and a predetermined pressure applied to the cylinder 20. It consists of a tank 22 for supplying hydraulic pressure and two check valves 23 and 24 for regulating the direction of oil flow. The cylinder 20 is always urged in the protruding direction by the elastic member 20a regardless of the presence or absence of hydraulic pressure. Further, the tank 22 supplies a hydraulic pressure of a predetermined pressure to the cylinder 20 by the elastic member 22a.
第１押圧部材１７は、スライドベース２に固定されたシリンダ２０のロッド２０ｂの先端に取り付けられている。従って、第１押圧部材１７が被圧入部材Ｗ及び圧入部材Ｐ１を押圧する圧力は、リリーフバルブ２１の設定圧を超えることはない。リリーフバルブ２１の設定圧は、圧入部材Ｐ１や被圧入部材Ｗを破損することなく、円滑に圧入部材Ｐ１，Ｐ２を被圧入部材Ｗに圧入することができる値に設定される。 The first pressing member 17 is attached to the tip of the rod 20 b of the cylinder 20 fixed to the slide base 2. Therefore, the pressure at which the first pressing member 17 presses the press-fitted member W and the press-fitting member P1 does not exceed the set pressure of the relief valve 21. The set pressure of the relief valve 21 is set to a value that allows the press-fit members P1, P2 to be smoothly press-fitted into the press-fit member W without damaging the press-fit member P1 and the press-fit member W.
次に、本発明に係る圧入方法及びその装置の動作を、図５の圧入方法の作業手順を示すフローチャートに従って説明する。 Next, the operation of the press-fitting method and the apparatus according to the present invention will be described with reference to the flowchart showing the work procedure of the press-fitting method of FIG.
先ず、ステップＳＰ１（セット工程）において、図１に示ように、原位置にある中間プレート１０に被圧入部材Ｗを位置決めセットする。更に、下方から圧入する圧入部材Ｐ１を第１圧入パンチ１１に嵌装してセットし、上方から圧入する圧入部材Ｐ２を第２圧入パンチ１６に嵌装してセットする。 First, in step SP1 (setting process), as shown in FIG. 1, the press-fitting member W is positioned and set on the intermediate plate 10 at the original position. Further, the press-fitting member P1 that is press-fitted from below is fitted and set on the first press-fitting punch 11, and the press-fitting member P2 that is press-fitted from above is fitted and set on the second press-fitting punch 16.
次いで、ステップＳＰ２（第１圧入工程）において、シリンダ（不図示）の前進駆動によりスライドベース２を原位置から所定のストロークだけ下降させる。すると、第１押圧部材１７は、中間プレート１０に位置決めセットされている被圧入部材Ｗを弾性部材１５に抗して押し下げる。そして、被圧入部材Ｗが第１圧入パンチ１１に嵌装してセットされている圧入部材Ｐ１の位置まで押し下げられると、圧入部材Ｐ１が被圧入部材Ｗに下方から圧入される（図２）。 Next, in step SP2 (first press-fitting process), the slide base 2 is lowered from the original position by a predetermined stroke by a forward drive of a cylinder (not shown). Then, the first pressing member 17 pushes down the press-fit member W positioned and set on the intermediate plate 10 against the elastic member 15. When the press-fitting member W is pushed down to the position of the press-fitting member P1 fitted and set to the first press-fitting punch 11, the press-fitting member P1 is press-fitted into the press-fitting member W from below (FIG. 2).
この時、圧力調整手段１８を構成するシリンダ２０は、タンク２２からチェックバルブ２３を通して供給された所定圧の油圧により、ロッド２０ｂを介して所定の圧力で第１押圧部材１７を押圧している。 At this time, the cylinder 20 constituting the pressure adjusting means 18 presses the first pressing member 17 with a predetermined pressure via the rod 20b by a predetermined pressure of hydraulic pressure supplied from the tank 22 through the check valve 23.
次いで、ステップＳＰ３（第２圧入工程）において、更にシリンダ（不図示）の前進駆動によりスライドベース２が下降すると、第２圧入パンチ１６に嵌装してセットされている圧入部材Ｐ２が、中間プレート１０に位置決めセットされ第２押圧部材１２に当接している被圧入部材Ｗに上方から圧入される（図３）。 Next, in step SP3 (second press-fitting process), when the slide base 2 is further lowered by forward drive of a cylinder (not shown), the press-fitting member P2 fitted and set on the second press-fitting punch 16 is moved to the intermediate plate. Then, it is press-fitted from above into the press-fit member W positioned at 10 and in contact with the second pressing member 12 (FIG. 3).
この時、スライドベース２の更なる下降により、第１押圧部材１７は、被圧入部材Ｗと圧入部材Ｐ１を第１圧入パンチ１１と共に押圧する。しかし、第１押圧部材１７が被圧入部材Ｗ及び圧入部材Ｐ１を押圧する圧力は、シリンダ２０内の圧力がリリーフバルブ２１の設定圧を超えると、リリーフバルブ２１が作動してシリンダ２０内の油がリリーフバルブ２１、チェックバルブ２４を通ってタンク２２に戻るため、リリーフバルブ２１の設定圧を超えることはない。 At this time, as the slide base 2 is further lowered, the first pressing member 17 presses the pressed member W and the pressing member P1 together with the first press punch 11. However, the pressure at which the first pressing member 17 presses the press-fitted member W and the press-fitting member P1 is such that when the pressure in the cylinder 20 exceeds the set pressure of the relief valve 21, the relief valve 21 is activated and the oil in the cylinder 20 However, since the pressure returns to the tank 22 through the relief valve 21 and the check valve 24, the set pressure of the relief valve 21 is not exceeded.
従って、第２圧入パンチ１６に嵌装してセットされている圧入部材Ｐ２が被圧入部材Ｗに上方から圧入される際に、既に下方から圧入されている圧入部材Ｐ１や被圧入部材Ｗに過度の圧力が掛からず、圧入部材Ｐ１や被圧入部材Ｗを破損することがない。 Therefore, when the press-fitting member P2 fitted and set on the second press-fitting punch 16 is press-fitted into the press-fitted member W from above, it is excessively applied to the press-fitting member P1 and the press-fitted member W already press-fitted from below. The press-fitting member P1 and the press-fitted member W are not damaged.
次いで、ステップＳＰ４において、シリンダ（不図示）の後退駆動によりスライドベース２が所定のストロークだけ上昇する。すると、第１押圧部材１７が被圧入部材Ｗを押圧しているので、先ず第２圧入パンチ１６から円滑に圧入部材Ｐ２が外れて圧入部材Ｐ２が被圧入部材Ｗに圧入嵌合した状態で、第２圧入パンチ１６は上昇することができる。 Next, in step SP4, the slide base 2 is raised by a predetermined stroke by a backward drive of a cylinder (not shown). Then, since the first pressing member 17 presses the press-fitting member W, first, the press-fitting member P2 is smoothly removed from the second press-fitting punch 16, and the press-fitting member P2 is press-fitted to the press-fitting member W. The second press punch 16 can be raised.
次いで、ステップＳＰ５において、スライドベース２が更に上昇すると、第１押圧部材１７が被圧入部材Ｗから離れ、弾性部材１５により中間プレート１０が原位置に戻ることにより第１圧入パンチ１１から円滑に圧入部材Ｐ１が外れて圧入部材Ｐ１が被圧入部材Ｗに圧入嵌合した状態でいる。
そして、スライドベース２は原位置に戻り、圧入作業の１サイクルが終了する。
Next, in step SP5, when the slide base 2 is further raised, the first pressing member 17 is separated from the press-fitting member W, and the intermediate plate 10 is returned to the original position by the elastic member 15, thereby smoothly press-fitting from the first press-fitting punch 11. The member P1 is detached and the press-fitting member P1 is press-fitted to the press-fitted member W.
Then, the slide base 2 returns to the original position, and one cycle of press-fitting work is completed.
なお、圧入部材Ｐ１，Ｐ２が第１圧入パンチ１１又は第２圧入パンチ１６に嵌装している時の結合力よりも、圧入部材Ｐ１，Ｐ２が被圧入部材Ｗに圧入嵌合している時の結合力の方が強いことが必要である。 When the press-fitting members P1 and P2 are press-fitted to the press-fitted member W, rather than the coupling force when the press-fitting members P1 and P2 are fitted to the first press-fitting punch 11 or the second press-fitting punch 16. It is necessary that the bond strength of is stronger.
このように、シリンダ（不図示）の１ストローク動作の下降・上昇によって、過度の圧力を圧入部材Ｐ１及び被圧入部材Ｗに掛けることなく、複数の圧入部材Ｐ１，Ｐ２を上下方向から被圧入部材Ｗに圧入することができる。 As described above, the press-fitting members P1 and P2 are pressed from above and below without applying excessive pressure to the press-fitting member P1 and the press-fitting member W by the lowering and raising of the one-stroke operation of the cylinder (not shown). Press fit into W.
また、本発明の実施の形態では、第１圧入工程で第１圧入パンチ１１と第１押圧部材１７により下方から圧入部材Ｐ１を被圧入部材Ｗに圧入し、第２圧入工程で第２圧入パンチ１６と第２押圧部材１２により上方から圧入部材Ｐ２を被圧入部材Ｗに圧入している。 Further, in the embodiment of the present invention, the press-fitting member P1 is press-fitted into the press-fitted member W from below by the first press-fitting punch 11 and the first pressing member 17 in the first press-fitting process, and the second press-fitting punch in the second press-fitting process. 16 and the second pressing member 12 press-fit the press-fitting member P2 into the press-fitted member W from above.
しかし、第１圧入工程で第２圧入パンチ１６と第２押圧部材１２により上方から圧入部材Ｐ２を被圧入部材Ｗに圧入し、第２圧入工程で第１圧入パンチ１１と第１押圧部材１７により下方から圧入部材Ｐ１を被圧入部材Ｗに圧入することもできる。その場合、第２圧入工程において第２押圧部材１２が被圧入部材Ｗ及び圧入部材Ｐ２を押圧する圧力が所定の圧力を超えないように、圧力調整手段１８を第２押圧部材１２に設ける必要がある。 However, in the first press-fitting process, the press-fitting member P2 is press-fitted into the press-fitted member W from above by the second press-fitting punch 16 and the second pressing member 12, and in the second press-fitting process, the first press-fitting punch 11 and the first pressing member 17 The press-fitting member P1 can be press-fitted into the press-fitted member W from below. In that case, it is necessary to provide the pressure adjusting means 18 on the second pressing member 12 so that the pressure at which the second pressing member 12 presses the pressed member W and the pressing member P2 does not exceed a predetermined pressure in the second press-fitting step. is there.
