Description

本発明は樹脂を基材とするワークを振動溶着させる振動溶着装置に関する。   The present invention relates to a vibration welding apparatus for vibrating and welding a workpiece based on a resin.

従来、樹脂を基材とするワークを振動溶着させる振動溶着機が知られている。この振動溶着機は、図１７に示すように、主プレート状の基部１Ｘと、振動溶着させる振動を発生させる振動体２Ｘと、振動体２Ｘを振動させる電磁ソレノイドで形成された加振源３Ｘと、振動体２Ｘの一方の片面２１Ｘにボルト状の第１締結具８Ｘにより固定された固定プレート２５Ｘと、振動体２Ｘに連動して振動する上ワーク保持部５Ｘと、振動体２Ｘの他方の片面２２Ｘと基部１Ｘとの間に介在するバネ性を有する弾性部材４Ｘとを備えている（特許文献１、非特許文献１）。樹脂を基材とする溶着すべきワークＷは、上ワーク保持部５Ｘと下ワーク保持部６Ｘとにより保持される。   2. Description of the Related Art Conventionally, there is known a vibration welding machine that performs vibration welding of a workpiece based on a resin. As shown in FIG. 17, the vibration welding machine includes a main plate-shaped base 1X, a vibration body 2X that generates vibrations for vibration welding, and an excitation source 3X formed by an electromagnetic solenoid that vibrates the vibration body 2X. The fixing plate 25X fixed to one side 21X of the vibrating body 2X by a bolt-shaped first fastener 8X, the upper work holding portion 5X that vibrates in conjunction with the vibrating body 2X, and the other side of the vibrating body 2X And an elastic member 4X having a spring property interposed between 22X and the base 1X (Patent Document 1, Non-Patent Document 1). The workpiece W to be welded using a resin as a base material is held by the upper workpiece holding portion 5X and the lower workpiece holding portion 6X.

使用に際しては、ワークＷを保持する前の段階で、図１７に示すように、上ワーク保持部５Ｘを下ワーク保持部６Ｘと共に矢印Ｙ１方向に持ち上げ、基部１Ｘ側の固定プレート２５Ｘに当てがう。そして上ワーク保持部５Ｘの保持プレート５０Ｘの取付孔５２Ｘに通したボルト状の第２締結具５３Ｘを、固定プレート２５Ｘの取付孔２６Ｘに締結させる。これにより上ワーク保持部５Ｘの保持プレート５０Ｘを基部１Ｘ側の固定プレート２５Ｘに着脱可能に固定させる。   In use, before holding the workpiece W, as shown in FIG. 17, the upper workpiece holding portion 5X is lifted in the direction of the arrow Y1 together with the lower workpiece holding portion 6X and applied to the fixing plate 25X on the base portion 1X side. . Then, the bolt-shaped second fastener 53X that is passed through the mounting hole 52X of the holding plate 50X of the upper work holding unit 5X is fastened to the mounting hole 26X of the fixing plate 25X. Accordingly, the holding plate 50X of the upper work holding unit 5X is detachably fixed to the fixing plate 25X on the base 1X side.

樹脂を基材とするワークＷを振動溶着させる際には、加振源３Ｘの励磁巻線３２Ｘに交流の励磁電流を通電させることにより、加振源３ＸにＮ極及びＳ極を交互に生成させる。これにより振動体２Ｘの端側の可動鉄心２４Ｘを矢印Ｋ１，Ｋ２方向に往復振動させる。この結果、上ワーク保持部５Ｘに保持されているワークＷに振動が伝播される。従って、ワークＷの接合境界面で発生する摩擦熱を利用して、ワークＷを振動溶着させる。
特開平１１−２７７６３１号公報 Liner Vibration Welder，振動溶着，平成１６年７月８日検索，インターネット，http://www.branson-jp.com/products/lvm-tech.html When the workpiece W made of resin is vibration welded, an alternating excitation current is passed through the excitation winding 32X of the excitation source 3X to alternately generate N and S poles in the excitation source 3X. Let Thereby, the movable iron core 24X on the end side of the vibrating body 2X is reciprocally vibrated in the directions of arrows K1 and K2. As a result, vibration is transmitted to the workpiece W held by the upper workpiece holding portion 5X.

以下、本発明の実施例１を図１〜図７を参照して説明する。複雑化を避けるため、図面のハッチングは省略されている。振動溶着装置は、樹脂を基材とするワークＷを振動溶着させるものである。図１，図２に示すように振動溶着工程は第１工程と第２工程とで形成されている。第１振動ユニット９ｆは振動溶着の第１工程を実施するためのものである。まず、第１振動ユニット９ｆについて図３〜図５を参照して説明を加える。図３に示すように、振動溶着装置は、横方向に沿って延びる平坦な固定面１０をもつ基部１と、左右方向（矢印Ｋ１，Ｋ２方向）に振動する振動体２ｆと、振動体２を振動させる駆動源となる加振源３と、振動体２ｆの他方の片面２２（上面）と基部１との間に介在するバネ性を有する弾性部材４ｆと、振動体２ｆに連動して振動するワーク保持部として機能する上ワーク保持部５ｆとを備えている。更に、上ワーク保持部５ｆの上ワーク保持面５０と対をなす下ワーク保持面６０を有する下ワーク保持部６ｆが設けられている。なお、下ワーク保持部６ｆは、昇降アクチェエータとして機能する昇降シリンダ装置２００ｆにより矢印Ｙ１，Ｙ２方向に昇降可能とされている（図１参照）。   Embodiment 1 of the present invention will be described below with reference to FIGS. In order to avoid complication, hatching of the drawings is omitted. The vibration welding apparatus is for vibration welding of a workpiece W having a resin as a base material. As shown in FIGS. 1 and 2, the vibration welding process is formed by a first process and a second process. The first vibration unit 9f is for carrying out the first step of vibration welding. First, the first vibration unit 9f will be described with reference to FIGS. As shown in FIG. 3, the vibration welding apparatus includes a base 1 having a flat fixed surface 10 extending in the lateral direction, a vibrating body 2f that vibrates in the left-right direction (arrow K1, K2 direction), and the vibrating body 2. It vibrates in conjunction with the vibration source 2f, the vibration source 3f serving as a driving source to be vibrated, the elastic member 4f having a spring property interposed between the other one surface 22 (upper surface) of the vibration body 2f and the base 1. And an upper work holding part 5f that functions as a work holding part. Further, a lower work holding portion 6f having a lower work holding surface 60 that forms a pair with the upper work holding surface 50 of the upper work holding portion 5f is provided. The lower work holding portion 6f can be moved up and down in the directions of arrows Y1 and Y2 by a lifting cylinder device 200f functioning as a lifting actuator (see FIG. 1).

振動体２ｆは、横方向に沿って延びると共に互い背向する平坦な一方の片面２１（下面）と、平坦な他方の片面２２（上面）と、横方向の両端に設けられた立壁部２３と、立壁部２３に露出させて保持された鉄心２４ｆ（第１振動受け部）とをもつ。加振源３は加振源ホルダ３０により基部１の両端部に固定されている。加振源３は、加振源ホルダ３０に保持された巻線保持部３１と、巻線保持部３１に巻回され励磁電流が通電される励磁巻線３２とを有する。巻線保持部３１の端面３３は磁極とされている。励磁巻線３２に交流の励磁電流が通電されると、加振源３の巻線保持部３１の端面３３にＮ極及びＳ極が交互に発生する。従って、振動体２ｆの鉄心２４ｆに吸引力及び反発力が交互に与えられる。結果として、振動体２ｆは所定の周波数及び所定の振幅で矢印Ｋ１，Ｋ２方向（横方向）に往復振動する。   The vibrating body 2f includes a flat one surface 21 (lower surface) extending in the lateral direction and facing away from each other, the other flat one surface 22 (upper surface), and standing wall portions 23 provided at both ends in the lateral direction.

Therefore, a suction force and a repulsive force are alternately applied to the iron core 24f of the vibrating body 2f. As a result, the vibrating body 2f reciprocates in the directions of arrows K1 and K2 (lateral direction) at a predetermined frequency and a predetermined amplitude.

The stopper surface 15 is along the direction (arrow Y1, Y2 direction) intersecting the vertical direction, that is, the vibration direction (arrow K1, K2 direction) of the vibrating body 2f. Since the stopper surface 15 of the base 1 and the stoppered surface 75 of the mounting plate 7 are engaged, the vibration of the mounting plate 7f in the directions of the arrows K1 and K2 of the vibrating body 2f is restricted during vibration welding.

図３に示すように、クランプ１０２は、上ワーク保持部５ｆに向かうにつれてつまり下方（矢印Ｙ２方向）に向かうにつれて拡開する第２傾斜面１１３と、第２傾斜面１１３で区画された凸部１１４と、凸部１１４に繋がる軸部１１５と、軸部１１５に繋がるピストン１１６とを有する。ピストン１１６は、油圧シリンダ装置１０３のシリンダ１０６内を油圧室１０４と油圧室１０５とに区画する。油圧ポンプ１０８の駆動により油圧室１０４に油が供給されると共に、油圧室１０５の油が吐出されると、ピストン１１６が上ワーク保持部５ｆから離間するように上方（矢印Ｙ１方向）に付勢される。この結果、第１振動ユニット９ｆの取付盤７ｆが基部１の固定面１０に固定され、第１振動ユニット９ｆの取付盤７ｆの着脱分離面９０ｆは基部１の固定面１０に密着する。これに対して、油圧室１０５に油が供給されると共に、油圧室１０４の油が吐出されると、ピストン１１６が上ワーク保持部５に向かうように下方（矢印Ｙ２方向）に付勢され、第１振動ユニット９ｆの取付盤７ｆの着脱分離面９０と基部１の固定面１０との密着が解除される。このように密着が解除されたとしても、溝状の被係合部１０１の第１傾斜面１１０と凸部１１４の第２傾斜面１１３との係合により、第１振動ユニット９ｆの取付盤７ｆの外れ落下は防止される。   As shown in FIG. 3, the clamp 102 has a second inclined surface 113 that expands toward the upper work holding portion 5 f, that is, downward (in the direction of arrow Y <b> 2), and a convex portion that is partitioned by the second inclined surface 113. 114, a shaft portion 115 connected to the convex portion 114, and a piston 116 connected to the shaft portion 115. The piston 116 partitions the inside of the cylinder 106 of the hydraulic cylinder device 103 into a hydraulic chamber 104 and a hydraulic chamber 105. When the hydraulic pump 108 is driven to supply oil to the hydraulic chamber 104 and the oil in the hydraulic chamber 105 is discharged, the piston 116 is biased upward (in the direction of arrow Y1) so as to be separated from the upper work holding portion 5f. Is done. As a result, the mounting plate 7 f of the first vibration unit 9 f is fixed to the fixed surface 10 of the base 1, and the detachable separation surface 90 f of the mounting plate 7 f of the first vibration unit 9 f is in close contact with the fixed surface 10 of the base 1. In contrast, when the oil is supplied to the hydraulic chamber 105 and the oil in the hydraulic chamber 104 is discharged, the piston 116 is urged downward (in the direction of arrow Y2) toward the upper work holding portion 5, The adhesion between the attachment / detachment separation surface 90 of the mounting plate 7f of the first vibration unit 9f and the fixed surface 10 of the base 1 is released. Even if the close contact is released in this way, the mounting plate 7f of the first vibration unit 9f is engaged by the engagement between the first inclined surface 110 of the groove-like engaged portion 101 and the second inclined surface 113 of the convex portion 114. The fall off is prevented.

ところで、第１振動ユニット９ｆの着脱分離面９０ｆを振動溶着機の基部１の固定面１０に固定させるにあたっては、まず、第１振動ユニット９ｆの着脱分離面９０ｆを基部１の固定面１０に対面させる。この場合、図３の紙面に対して垂直な方向に沿って基部１に対して第１振動ユニット９ｆを移動させる。ここで、クランプ１０２の凸部１１４は基部１の固定面１０から露出しているため、クランプ１０２の凸部１１４と第１振動ユニット９ｆの取付盤７ｆの溝状の被係合部１０１とを嵌合させることができる。このように嵌合させた状態で、第１振動ユニット９ｆと共に取付盤７ｆを図３の紙面に対して垂直な方向（即ち、振動体２ｆの振動方向であるＫ１，Ｋ２方向と交差する方向）に沿って図略のアクチュエータまたは手作業などによりスライド移動させる。この場合、溝状の被係合部１０１の第１傾斜面１１０とクランプ１０２の凸部１１４の第２傾斜面１１３との係合により、第１振動ユニット９ｆの取付盤７ｆの外れ落下は防止される。この場合、被ストッパ面７５と基部１のストッパ面１５とを対面させれば、第１振動ユニット９ｆの取付盤７ｆを基部１に対して振動方向（矢印Ｘ１，Ｘ２方向）において位置決めする操作が容易となる。従って、取付盤７ｆの被ストッパ面７５と基部１のストッパ面１５とは、取付盤７ｆを基部１に固定するときにおける取付盤７ｆの位置決め手段としても機能することができる。   By the way, when fixing the attachment / detachment separation surface 90f of the first vibration unit 9f to the fixing surface 10 of the base 1 of the vibration welding machine, first, the attachment / detachment separation surface 90f of the first vibration unit 9f faces the fixing surface 10 of the base 1. Let In this case, the first vibration unit 9f is moved relative to the base 1 along a direction perpendicular to the paper surface of FIG. Here, since the convex part 114 of the clamp 102 is exposed from the fixed surface 10 of the base 1, the convex part 114 of the clamp 102 and the groove-like engaged part 101 of the mounting plate 7f of the first vibration unit 9f are connected. Can be fitted. In the state of being fitted in this way, the mounting plate 7f is moved together with the first vibration unit 9f in a direction perpendicular to the paper surface of FIG. 3 (that is, a direction intersecting with the directions K1 and K2 which are the vibration directions of the vibration body 2f). Are slid along the actuator by an unillustrated actuator or manually. In this case, by the engagement between the first inclined surface 110 of the groove-like engaged portion 101 and the second inclined surface 113 of the convex portion 114 of the clamp 102, the falling off of the mounting plate 7f of the first vibration unit 9f is prevented. Is done. In this case, if the stopper surface 75 and the stopper surface 15 of the base portion 1 face each other, an operation for positioning the mounting plate 7f of the first vibration unit 9f with respect to the base portion 1 in the vibration direction (arrow X1, X2 direction) is performed. It becomes easy. Therefore, the stopper surface 75 of the mounting board 7f and the stopper surface 15 of the base 1 can also function as positioning means for the mounting board 7f when the mounting board 7f is fixed to the base 1.

上記のようにして第１振動ユニット９ｆの取付盤７ｆの溝状の被係合部１０１と固定手段１００ｆのクランプ１０２の凸部１１４とを嵌める。その後、油圧供給装置１０７により、離脱用の油圧室１０５の油がこれの外方に吐出されると共に油圧ポンプ１０８により締め付け用の油圧室１０４に油が供給される。これによりピストン１１６が上ワーク保持部５ｆから離間するように付勢される。つまり、ピストン１１６が上方（矢印Ｙ１方向）に付勢され、第１振動ユニット９ｆの取付盤７ｆの着脱分離面９０ｆは基部１の固定面１０に密着する。これにより振動ユニット９ｆの着脱分離面９０ｆが基部１の固定面１０に固定される。このように第１振動ユニット９ｆの着脱分離面９０ｆが固定されている状態において、取付盤７ｆの被ストッパ面７５と基部１のストッパ面１５とが互いに対面しているため、第１振動ユニット９ｆの取付盤７ｆの固定性及び拘束性が向上する。この場合、基部１の固定面１０と取付盤７ｆの着脱分離面９０ｆとは広面積化されているため、固定面１０と着脱分離面９０ｆとの間における摩擦抵抗が確保され、この意味においても振動ユニット９ｆの取付盤７ｆの固定性が向上する。   As described above, the grooved engaged portion 101 of the mounting plate 7f of the first vibration unit 9f and the convex portion 114 of the clamp 102 of the fixing means 100f are fitted. Thereafter, oil in the detaching hydraulic chamber 105 is discharged outward by the hydraulic pressure supply device 107, and oil is supplied to the hydraulic chamber 104 for tightening by the hydraulic pump 108. Accordingly, the piston 116 is urged so as to be separated from the upper work holding portion 5f. That is, the piston 116 is urged upward (in the direction of the arrow Y1), and the attachment / detachment separation surface 90f of the mounting plate 7f of the first vibration unit 9f is in close contact with the fixed surface 10 of the base 1. As a result, the attachment / detachment separation surface 90 f of the vibration unit 9 f is fixed to the fixing surface 10 of the base 1. Thus, in the state where the attachment / detachment separation surface 90f of the first vibration unit 9f is fixed, the stopper surface 75 of the mounting board 7f and the stopper surface 15 of the base portion 1 face each other, so the first vibration unit 9f. The fixing property and restraint property of the mounting plate 7f are improved. In this case, since the fixed surface 10 of the base 1 and the attachment / detachment separation surface 90f of the mounting board 7f are widened, a frictional resistance is secured between the fixation surface 10 and the attachment / detachment separation surface 90f. Fixability of the mounting plate 7f of the vibration unit 9f is improved.

またワークＷｆを振動溶着させる際には、図１に示すように、下ワーク保持部６ｆがアクチュエータとしての昇降シリンダ装置２００ｆにより矢印Ｙ１方向に上昇し、下ワーク保持部６ｆと上ワーク保持部５ｆとでワークＷｆが挟持される。このようにワークＷｆが挟持されている状態で、加振源３の励磁巻線３２に交流の励磁電流が通電される。すると前述したように、加振源３の巻線保持部３１の端面３３にＮ極及びＳ極が交互に発生する。従って振動体２の鉄心２４に吸引力及び反発力が交互に与えられ、振動体２は所定の周波数及び所定の振幅で矢印Ｋ１，Ｋ２方向（横方向）に往復振動する。周波数は１００〜４００Ｈｚ、特に２００〜２５０Ｈｚを例示でき、振幅は０．５〜２．０ｍｍ、特に１．０〜１．８ｍｍを例示できる。但しこれらに限定されるものではない。   When the workpiece Wf is welded by vibration, as shown in FIG. 1, the lower workpiece holding portion 6f is raised in the direction of the arrow Y1 by the lifting cylinder device 200f as an actuator, and the lower workpiece holding portion 6f and the upper workpiece holding portion 5f. And the workpiece Wf is clamped. With the workpiece Wf being held in this way, an alternating excitation current is applied to the excitation winding 32 of the excitation source 3. Then, as described above, the N pole and the S pole are alternately generated on the end face 33 of the winding holding part 31 of the vibration source 3. Accordingly, an attractive force and a repulsive force are alternately applied to the iron core 24 of the vibrating body 2, and the vibrating body 2 reciprocates in the directions of arrows K1 and K2 (lateral direction) at a predetermined frequency and a predetermined amplitude. The frequency may be 100 to 400 Hz, particularly 200 to 250 Hz, and the amplitude may be 0.5 to 2.0 mm, particularly 1.0 to 1.8 mm. However, it is not limited to these.

第１振動体２ｆの振動は第１振動ユニット９ｆの上ワーク保持部５ｆに伝播される。これによりワークＷｆを構成する複数の部品が摩擦熱に基づいて互いに振動溶着されて接合される。ワークＷｆは一般的には熱可塑性樹脂で形成されている。ワークＷｆの用途及び種類としては特に制限されず、インテークマニホルド、ランプ、グローブボックス、レゾネータ、インストルメントパネルなどが例示される。   The vibration of the first vibrating body 2f is propagated to the upper work holding portion 5f of the first vibrating unit 9f. Thereby, a plurality of parts constituting the work Wf are vibration welded to each other based on the frictional heat and joined. The workpiece Wf is generally formed of a thermoplastic resin. The use and type of the workpiece Wf are not particularly limited, and examples include an intake manifold, a lamp, a glove box, a resonator, and an instrument panel.

図６及び図７は振動溶着の第２工程を実施する第２振動ユニット９ｓを示す。第２振動ユニット９ｓは振動溶着の第２工程を実施するためのものである。第２振動ユニット９ｓは第１振動ユニット９ｆと基本的には同様の構成、作用効果を有するので、第２振動ユニット９ｓの要部のみを説明する。図６に示すように、第２振動体２ｓと、第２上ワーク保持部５ｓ、第２弾性部材４ｓ、第２取付盤７ｓは締結により一体化され、第２振動ユニット９ｓとされている。そして第２振動ユニット９ｓを構成する第２取付盤７ｓのうち、基部１の固定面１０に対面する面、つまり、第２上ワーク保持部５ｓと反対側に位置する上面は、振動溶着機の基部１に着脱される第２着脱分離面９０ｓとされている。   6 and 7 show a second vibration unit 9s that performs the second step of vibration welding. The second vibration unit 9s is for carrying out the second step of vibration welding. Since the second vibration unit 9s has basically the same configuration and function as the first vibration unit 9f, only the main part of the second vibration unit 9s will be described. As shown in FIG. 6, the second vibrating body 2s, the second upper work holding portion 5s, the second elastic member 4s, and the second mounting plate 7s are integrated by fastening to form a second vibrating unit 9s. Of the second mounting plate 7 s constituting the second vibration unit 9 s, the surface facing the fixed surface 10 of the base 1, that is, the upper surface located on the side opposite to the second upper work holding portion 5 s is the surface of the vibration welding machine. A second attaching / detaching separation surface 90s attached to and detached from the base 1 is used.

図６に示すように、第２振動ユニット９ｓを構成する第２取付盤７ｓの第２着脱分離面９０ｓには、複数の溝状をなす被係合部１０１が設けられている。第２振動ユニット９ｓを基部１の固定面１０に固定させる第２固定手段１００ｓが設けられている。第２固定手段１００ｓは、基部１に設けられ取付盤７ｓの凹状の被係合部１０１に係合する複数の凸状をなす係合部としてのクランプ１０２と、基部１に設けられた付勢部として機能できる油圧シリンダ装置１０３（流体圧シリンダ装置）とを備えている。   As shown in FIG. 6, a plurality of engaged portions 101 having a plurality of groove shapes are provided on the second detachable separation surface 90 s of the second mounting plate 7 s constituting the second vibration unit 9 s. A second fixing means 100 s for fixing the second vibration unit 9 s to the fixing surface 10 of the base 1 is provided. The second fixing means 100s includes a clamp 102 as a plurality of convex engaging portions provided on the base 1 and engaged with the concave engaged portions 101 of the mounting plate 7s, and an urging provided on the base 1. And a hydraulic cylinder device 103 (fluid pressure cylinder device) that can function as a unit.

さて、図１及び図２に示すように、基部１のうち振動ユニット９ｆ，９ｓと対向する面１４には、レール状をなす加振源案内部３５が設けられている。加振源案内部３５は一端３５ａから他端３５ｃにかけて横方向に沿って延設されている。図１及び図２に示すように、加振源３をスライド移動させる加振源アクチェエータ３００が設けられている。加振源アクチェエータ３００は、油圧で作動する油圧シリンダ装置３０１と、油圧シリンダ装置３０１により矢印Ｘ１，Ｘ２方向（つまり、振動ユニット９ｆ，９ｓが並設されている方向）に移動するピストンロッド状の可動体３０２とを備えている。可動体３０２の先端部３０２ｃは可動式の加振源３に接続されている。図１及び図２に示すように、油圧シリンダ装置３０１は、加振源３を矢印Ｘ１方向に前進させる前進室３０３と、加振源３を矢印Ｘ２方向に後退させる後退室３０４と、前進端面３０５と、後退端面３０６とを有する。なお、油圧シリンダ装置３０１を空気圧シリンダ装置としても良いし、モータ装置としても良い。   As shown in FIGS. 1 and 2, a vibration source guide portion 35 having a rail shape is provided on the surface 14 of the base portion 1 facing the vibration units 9 f and 9 s. The excitation source guide 35 extends in the lateral direction from one end 35a to the other end 35c. As shown in FIGS. 1 and 2, a vibration source actuator 300 that slides the vibration source 3 is provided. The excitation source actuator 300 includes a hydraulic cylinder device 301 that operates by hydraulic pressure, and a piston rod-like shape that moves in the directions of arrows X1 and X2 (that is, the direction in which the vibration units 9f and 9s are arranged in parallel) by the hydraulic cylinder device 301. A movable body 302 is provided. A distal end portion 302 c of the movable body 302 is connected to the movable excitation source 3. As shown in FIGS. 1 and 2, the hydraulic cylinder device 301 includes an advance chamber 303 that advances the vibration source 3 in the direction of the arrow X1, a retraction chamber 304 that moves the vibration source 3 in the direction of the arrow X2, and a forward end surface. 305 and a receding end surface 306. The hydraulic cylinder device 301 may be a pneumatic cylinder device or a motor device.

図３に示すように、前記した加振源案内部３５は、振動体２の振動方向（矢印Ｋ１，Ｋ２方向，つまり横方向）の両端側に設けられている。加振源案内部３５は、基部１の内部に固定された第１案内部３５ａと、基部１から露出する第２案内部３５ｂとで形成されている。加振源案内部３５は、第１振動体２ｆ，第２振動体２ｓの振動方向（矢印Ｋ１，Ｋ２方向）と交差する方向（矢印Ｘ１，Ｘ２方向）に沿って延設されている。図１に示すように、加振源３は、基部１の両端部に保持された巻線保持部３１と、巻線保持部３１に巻回され励磁電流が通電される励磁巻線３２とを有する。加振源３は加振源ホルダ３０に保持されている。加振源ホルダ３０は加振源３と共に加振源案内部３５に沿って振動体２の振動方向と交差する方向（矢印Ｘ１方向，Ｘ２方向）に沿ってスライド移動できるように設定されている。   As shown in FIG. 3, the above-described excitation source guide portions 35 are provided on both ends of the vibration body 2 in the vibration direction (the directions of the arrows K1, K2, that is, the lateral direction). The excitation source guide 35 is formed of a first guide 35 a fixed inside the base 1 and a second guide 35 b exposed from the base 1. The excitation source guide part 35 is extended along the direction (arrow X1, X2 direction) which cross | intersects the vibration direction (arrow K1, K2 direction) of the 1st vibrating body 2f and the 2nd vibrating body 2s. As shown in FIG. 1, the excitation source 3 includes a winding holding part 31 held at both ends of the base 1 and an excitation winding 32 wound around the winding holding part 31 and energized with an excitation current. Have. The vibration source 3 is held by a vibration source holder 30. The excitation source holder 30 is set so as to be slidable along the direction (arrow X1 direction, X2 direction) that intersects the vibration direction of the vibrating body 2 along the excitation source guide 35 together with the excitation source 3. .

まず、第１振動ユニット９ｆを振動溶着機の基部１の固定面１０に固定させるにあたっては、実施例１の場合と同様に、第１振動ユニット９ｆの上面である第１着脱分離面９０を基部１の固定面１０に対面させる。この場合、図１の紙面に対して垂直な方向に沿って第１振動ユニット９ｆを移動させる。この場合、クランプ１０２の凸部１１４は基部１の固定面１０から露出しているため、クランプ１０２の凸部１１４と第１振動ユニット９ｆの取付盤７ｆの溝状の被係合部１０１とを嵌合させる。このように嵌合させた状態で、第１振動ユニット９ｆと共に取付盤７ｆを図１の紙面に対して垂直な方向（即ち、振動体２の振動方向である矢印Ｋ１，Ｋ２方向と交差する方向）に沿ってスライド移動させる。この場合、溝状の被係合部１０１の第１傾斜面１１０と凸部１１４の第２傾斜面１１３との係合により、第１振動ユニット９ｆの取付盤７ｆの外れ落下は防止される。この場合、被ストッパ面７５と基部１のストッパ面１５とを対面させれば、第１振動ユニット９ｆの取付盤７ｆを振動方向（矢印Ｋ１，Ｋ２方向）において位置決めする操作が容易となる。   First, when the first vibration unit 9f is fixed to the fixing surface 10 of the base 1 of the vibration welder, the first attachment / detachment separation surface 90 which is the upper surface of the first vibration unit 9f is used as the base as in the first embodiment. 1 is fixed to the fixed surface 10. In this case, the first vibration unit 9f is moved along a direction perpendicular to the paper surface of FIG. In this case, since the convex part 114 of the clamp 102 is exposed from the fixed surface 10 of the base 1, the convex part 114 of the clamp 102 and the groove-like engaged part 101 of the mounting plate 7f of the first vibration unit 9f are connected. Fit. In the state of being fitted in this way, the mounting plate 7f together with the first vibration unit 9f is perpendicular to the plane of FIG. 1 (that is, the direction intersecting the directions of arrows K1 and K2 which are the vibration directions of the vibrator 2). ) Slide it along. In this case, the engagement between the first inclined surface 110 of the grooved engaged portion 101 and the second inclined surface 113 of the convex portion 114 prevents the mounting plate 7f of the first vibration unit 9f from falling off. In this case, if the stopper surface 75 and the stopper surface 15 of the base portion 1 face each other, an operation of positioning the mounting plate 7f of the first vibration unit 9f in the vibration direction (arrow K1, K2 direction) becomes easy.

その後、油圧室１０５の油がこれの外方に吐出されると共に、油圧ポンプ１０８により油圧室１０４に油が供給される。この結果、ピストン１１６が第１上ワーク保持部５ｆから離間するように上方（矢印Ｙ１方向）に付勢される。従って、第１振動ユニット９ｆの第１取付盤７ｆの第１着脱分離面９０ｆが基部１の固定面１０に密着する。これにより第１振動ユニット９ｆが基部１の固定面１０に固定される。なお、第２振動ユニット９ｓも同様な手順により基部１の固定面１０に固定される。   Thereafter, the oil in the hydraulic chamber 105 is discharged to the outside, and the oil is supplied to the hydraulic chamber 104 by the hydraulic pump 108. As a result, the piston 116 is urged upward (in the direction of the arrow Y1) so as to be separated from the first upper work holding portion 5f. Accordingly, the first attachment / detachment separation surface 90 f of the first mounting plate 7 f of the first vibration unit 9 f is in close contact with the fixed surface 10 of the base 1. As a result, the first vibration unit 9 f is fixed to the fixing surface 10 of the base 1. The second vibration unit 9s is also fixed to the fixing surface 10 of the base 1 by the same procedure.

次に、第１振動ユニット９ｆにおいて振動溶着工程の第１工程を実施させる場合について説明する。この場合、図５に示すように、第１下ワーク保持部６ｆが第１昇降シリンダ装置２００ｆにより矢印Ｙ１方向に上昇され、振動溶着の第２工程が実施される予定のワークＷｆが第１上ワーク保持部５ｆと第１下ワーク保持部６ｆとで挟持されている。そして、図１から理解できるように、加振源アクチェエータ３００の後退室３０４に油圧を供給し、可動体３０２の端面３０２ｘを矢印Ｘ２方向に移動させ、後退端面３０６に位置決めを兼ねて当接させる。この状態では図７に示すように、加振源３は第１振動ユニット９ｆの第１振動体２ｆに対面させ、第１形態に設定する。このように第１形態に設定した状態で、加振源３の励磁巻線３２に交流の励磁電流が通電される。すると加振源３と第１振動ユニット９ｆの第１振動体２ｆとは対面しているため、前述したように、第１振動体２ｆは所定の周波数及び所定の振幅で矢印Ｋ１，Ｋ２方向（横方向）に往復振動する。第１振動体２ｆの振動は第１振動ユニット９ｆの第１上ワーク保持部５ｆに伝播される。これにより第１上ワーク保持部５ｆに支持されているワークＷｆを構成する複数の部品が摩擦熱に基づいて互いに振動溶着されて接合される。   Next, a case where the first process of the vibration welding process is performed in the first vibration unit 9f will be described. In this case, as shown in FIG. 5, the first lower work holding portion 6f is raised in the direction of the arrow Y1 by the first elevating cylinder device 200f, and the work Wf scheduled to be subjected to the second step of vibration welding is the first upper It is clamped between the work holding part 5f and the first lower work holding part 6f. As can be understood from FIG. 1, the hydraulic pressure is supplied to the backward chamber 304 of the excitation source actuator 300, the end surface 302 x of the movable body 302 is moved in the direction of the arrow X <b> 2, and is brought into contact with the backward end surface 306 for positioning. . In this state, as shown in FIG. 7, the excitation source 3 is set to face the first vibrating body 2f of the first vibrating unit 9f and set to the first form. In this state set in the first form, an alternating excitation current is applied to the excitation winding 32 of the excitation source 3. Then, since the vibration source 3 and the first vibrating body 2f of the first vibrating unit 9f face each other, as described above, the first vibrating body 2f has a predetermined frequency and a predetermined amplitude in the directions of the arrows K1, K2 ( (Oscillates in the horizontal direction). The vibration of the first vibrating body 2f is propagated to the first upper work holding portion 5f of the first vibrating unit 9f. As a result, a plurality of components constituting the workpiece Wf supported by the first upper workpiece holding portion 5f are vibration welded to each other based on the frictional heat and joined.

振動溶着の第１工程の間、加振源アクチュエータ３００の油圧シリンダ装置３０１の後退室３０４に油圧を供給することにより、可動体３０２を後退端面３０６に位置決めを兼ねて当接させる手段が採られている（図１参照）。このため振動溶着の第１工程において加振源３の矢印Ｘ１，Ｘ２方向への変位が抑制され、この意味においても振動溶着の高精度化、高品質化に有利である。   During the first step of vibration welding, means for bringing the movable body 302 into contact with the retracting end surface 306 by supplying hydraulic pressure to the retracting chamber 304 of the hydraulic cylinder device 301 of the vibration source actuator 300 is employed. (See FIG. 1). For this reason, in the first step of vibration welding, the displacement of the vibration source 3 in the directions of the arrows X1 and X2 is suppressed, and in this sense, it is advantageous for improving the accuracy and quality of vibration welding.

次に、第２振動ユニット９ｓにおいて振動溶着工程の第２工程を実施させる場合について説明を加える。この場合、図２から理解できるように、第２振動ユニット９ｓの第２下ワーク保持部６ｓが第２昇降シリンダ装置２００ｓにより矢印Ｙ１方向に上昇し、振動溶着の第２工程が実施される予定のワークＷｓが第２下ワーク保持部６ｓと第２上ワーク保持部６ｆとで挟持されている。そして、加振源アクチェエータ３００の前進室３０３に油を供給すると共に後退室３０４の油を吐出させることにより、可動体３０２を矢印Ｘ１方向に前進駆動させ、位置決めを兼ねて前進端面３０５に当接させる（図２参照）。これにより加振源３を加振源案内部３５に沿って矢印Ｘ１方向に向けてスライド移動させ、加振源３を第２振動ユニット９ｓの振動体２ｓの鉄心２４ｓに対面させ（図７参照）、第２形態に設定する。第２形態に設定した状態で、加振源３の励磁巻線３２に交流の励磁電流が通電される。すると前述したように、第２振動ユニット９ｓの第２振動体２ｓは矢印Ｋ１，Ｋ２方向（横方向）に往復振動する。第２振動体２ｓの振動は第２振動ユニット９ｓの第２上ワーク保持部５ｓに伝播される。これにより第２振動ユニット９ｓの第２上ワーク保持部５ｓに支持されているワークＷｓを構成する複数の部品が摩擦熱に基づいて互いに振動溶着される。振動溶着の第２工程の間、加振源アクチュエータ３００の油圧シリンダ装置３０１の前進室３０３に油圧を供給することにより、可動体３０２を前進端面３０５に位置決めを兼ねて当接させる手段が採られている。このため振動溶着の第２工程において加振源３の矢印Ｘ１，Ｘ２方向への変位が抑制され、この意味においても振動溶着の高品質化に有利である。なお振動溶着が終了したら、必要に応じて、加振源アクチェエータ３００の可動体３０２を矢印Ｘ２方向に作動させて元の位置に復帰させる。   Next, the case where the second process of the vibration welding process is performed in the second vibration unit 9s will be described. In this case, as can be understood from FIG. 2, the second lower work holding portion 6s of the second vibration unit 9s is raised in the direction of the arrow Y1 by the second lifting cylinder device 200s, and the second step of vibration welding is scheduled to be performed. The workpiece Ws is sandwiched between the second lower workpiece holding portion 6s and the second upper workpiece holding portion 6f. Then, by supplying oil to the forward chamber 303 of the vibration source actuator 300 and discharging the oil from the backward chamber 304, the movable body 302 is driven forward in the direction of the arrow X1 to contact the forward end surface 305 also for positioning. (See FIG. 2). As a result, the vibration source 3 is slid along the vibration source guide 35 in the direction of the arrow X1, and the vibration source 3 faces the iron core 24s of the vibrating body 2s of the second vibration unit 9s (see FIG. 7). ), Set to the second form. In the state set to the second form, an alternating excitation current is applied to the excitation winding 32 of the excitation source 3. Then, as described above, the second vibrating body 2s of the second vibrating unit 9s reciprocates in the directions of arrows K1 and K2 (lateral direction). The vibration of the second vibrating body 2s is propagated to the second upper work holding portion 5s of the second vibrating unit 9s. As a result, a plurality of parts constituting the work Ws supported by the second upper work holding portion 5s of the second vibration unit 9s are vibration welded to each other based on frictional heat. During the second step of vibration welding, a means for bringing the movable body 302 into contact with the forward end face 305 for positioning by supplying hydraulic pressure to the forward chamber 303 of the hydraulic cylinder device 301 of the vibration source actuator 300 is employed. ing. For this reason, in the second step of vibration welding, the displacement of the vibration source 3 in the directions of the arrows X1 and X2 is suppressed, and this is also advantageous for improving the quality of vibration welding. When the vibration welding is completed, the movable body 302 of the vibration source actuator 300 is actuated in the direction of the arrow X2 as necessary to return to the original position.

以上説明したように本実施例によれば、振動溶着の第１工程を行う第１振動ユニット９ｆ及び振動溶着の第２工程を行う第２振動ユニット９ｓが矢印Ｘ１，Ｘ２方向において並設されており、揺動溶着の生産性を高めるのに有利となる。更に、可動式の加振源３を加振源案内部３５に沿って第１振動ユニット９ｆ及び第２振動ユニット９ｓ間において移動させる。このため、加振源３は第１振動ユニット９ｆ及び第２振動ユニット９ｓの双方に共通化されている。よって加振源３を複数設けずとも良い。故に、生産性を高めつつ設備費を低減させることができる。加振源アクチェエータ３００により可動式の加振源３を加振源案内部３５に沿って移動させるため、移動操作が容易である。   As described above, according to this embodiment, the first vibration unit 9f that performs the first step of vibration welding and the second vibration unit 9s that performs the second step of vibration welding are arranged in parallel in the directions of the arrows X1 and X2. This is advantageous in increasing the productivity of swing welding. Further, the movable excitation source 3 is moved along the excitation source guide 35 between the first vibration unit 9f and the second vibration unit 9s. For this reason, the excitation source 3 is shared by both the first vibration unit 9f and the second vibration unit 9s. Therefore, it is not necessary to provide a plurality of excitation sources 3. Therefore, the facility cost can be reduced while increasing the productivity. Since the movable excitation source 3 is moved along the excitation source guide 35 by the excitation source actuator 300, the moving operation is easy.

本実施例によれば、振動体２ｆ、上ワーク保持部５ｆ、弾性部材４ｆ、取付盤７ｆは一体的化されて第１振動ユニット９ｆ（図１参照）とされている。そして、第１振動ユニット９ｆを構成する取付盤７ｆのうち上ワーク保持部５ｆと反対側に位置する面、つまり、基部１の固定面１０に対面する面が着脱分離面９０ｆされている。このように第１振動ユニット９ｆのうち振動溶着機に着脱される着脱分離面９０ｆは、振動体２ｆの振動が積極的に伝搬される上ワーク保持部５ｆと反対側に位置している。ここで、着脱分離面９０ｆは、振動溶着機の基部１と第１振動ユニット９ｆとを分割する境界である。かかる境界として機能する着脱分離面９０ｆと振動体２ｆとの間に弾性部材４ｆが介在しているため、着脱分離面９０ｆへの振動体２ｆの振動は弾性部材４ｆよりかなり吸収される。このため着脱分離面９０ｆは振動体２ｆの振動が伝播されにくい構造となる。故に振動溶着の際に振動体２ｆが振動し、その振動が上ワーク保持部５ｆに伝播されたとしても、第１振動ユニット９ｆの着脱分離面９０ｆへの振動伝播は抑制される。このため振動溶着の際に、着脱分離面９０ｆに摩耗、焼付等といった不具合が発生することが抑制される。故に、振動溶着機に着脱分離面９０ｆを取り付ける取付精度の信頼性を高めることができる。故に、振動溶着機に着脱分離面９０ｆを取り付ける取付精度の信頼性を高めることができ、振動溶着の高精度化、高品質化に有利となる。   According to the present embodiment, the vibrating body 2f, the upper work holding portion 5f, the elastic member 4f, and the mounting board 7f are integrated into a first vibration unit 9f (see FIG. 1). A surface located on the opposite side of the upper work holding portion 5f of the mounting plate 7f constituting the first vibration unit 9f, that is, a surface facing the fixed surface 10 of the base portion 1 is a detachable separation surface 90f. In this way, the detachable separation surface 90f of the first vibration unit 9f that is attached to and detached from the vibration welder is located on the side opposite to the upper work holding portion 5f through which the vibration of the vibrating body 2f is positively propagated. Here, the attachment / detachment separation surface 90f is a boundary that divides the base 1 of the vibration welder and the first vibration unit 9f. Since the elastic member 4f is interposed between the attachment / detachment separation surface 90f functioning as the boundary and the vibrating body 2f, the vibration of the vibration body 2f to the attachment / detachment separation surface 90f is considerably absorbed by the elastic member 4f. For this reason, the attachment / detachment separation surface 90f has a structure in which the vibration of the vibrating body 2f is difficult to propagate. Therefore, even if the vibrating body 2f vibrates during vibration welding and the vibration is propagated to the upper work holding portion 5f, vibration propagation to the attachment / detachment separation surface 90f of the first vibration unit 9f is suppressed. For this reason, the occurrence of problems such as wear and seizure on the detachable separation surface 90f during vibration welding is suppressed. Therefore, it is possible to improve the reliability of the mounting accuracy for attaching the detachable separation surface 90f to the vibration welding machine. Therefore, it is possible to increase the reliability of the mounting accuracy for attaching the detachable separation surface 90f to the vibration welding machine, which is advantageous for improving the accuracy and quality of vibration welding.

同様に振動溶着の際に、第２振動ユニット９ｓの着脱分離面９０ｓに摩耗、焼付等といった不具合が発生することが抑制される。故に、振動溶着機に着脱分離面９０ｓを取り付ける取付精度の信頼性を高めることができる。故に、振動溶着機に着脱分離面９０ｓを取り付ける取付精度の信頼性を高めることができ、振動溶着の高精度化、高品質化に有利となる。   Similarly, during vibration welding, occurrence of problems such as wear and seizure on the detachable separation surface 90s of the second vibration unit 9s is suppressed. Therefore, it is possible to improve the reliability of the mounting accuracy for attaching the detachable separation surface 90s to the vibration welding machine. Therefore, the reliability of the mounting accuracy for attaching the detachable separation surface 90s to the vibration welding machine can be increased, which is advantageous for high accuracy and high quality of vibration welding.

更に本実施例によれば、図１７に示す従来技術と異なり、第１振動ユニット９ｆの着脱分離面９０ｆを基部１の固定面１０に固定する方策としてボルト等の締結具を用いておらず、油圧シリンダ装置１０３を作動させれば良い。このため基部１に対して第１振動ユニット９ｆを交換する際の交換時間を短縮させることができる。   Furthermore, according to the present embodiment, unlike the prior art shown in FIG. 17, a fastener such as a bolt is not used as a measure for fixing the attaching / detaching separation surface 90f of the first vibration unit 9f to the fixing surface 10 of the base 1. The hydraulic cylinder device 103 may be operated. For this reason, the exchange time at the time of exchanging the 1st vibration unit 9f to base 1 can be shortened.

また本実施例によれば、第１振動ユニット９ｆの着脱分離面９０ｆを基部１の固定面１０に固定する固定手段１００ｆの主要素として機能する油圧シリンダ装置１０３が用いられている。このためワークＷｆを振動溶着させている際に、固定手段１００ｆのクランプ１０２が万一仮に瞬間的に緩んだとしても、油圧シリンダ装置１０３の締め付け用の油圧室１０４に油圧を作用させておけば、ピストン１１６が上ワーク保持部５ｆから離間するように上方（矢印Ｙ１方向）に再び付勢され、結果として、取付盤７ｆの着脱分離面９０ｆが基部１の固定面１０に密着するように取付盤７ｆが基部１の固定面１０に固定され続ける。このためワークＷｆの振動溶着を良好に行うことができ、振動溶着の信頼性を高めることができる。第２振動ユニット９ｓについても同様である。   Further, according to the present embodiment, the hydraulic cylinder device 103 that functions as a main element of the fixing means 100f that fixes the attaching / detaching separation surface 90f of the first vibration unit 9f to the fixing surface 10 of the base 1 is used. For this reason, when the workpiece Wf is vibrated and welded, even if the clamp 102 of the fixing means 100f is loosened momentarily, if the hydraulic pressure is applied to the hydraulic chamber 104 for tightening the hydraulic cylinder device 103, The piston 116 is again urged upward (in the direction of the arrow Y1) so as to be separated from the upper work holding portion 5f, and as a result, the attachment / detachment separation surface 90f of the mounting board 7f is attached so as to be in close contact with the fixing surface 10 of the base 1. The board 7 f continues to be fixed to the fixing surface 10 of the base 1. Therefore, vibration welding of the workpiece Wf can be performed satisfactorily, and the reliability of vibration welding can be improved. The same applies to the second vibration unit 9s.

更に、基部１のストッパ面１５と取付盤７ｆの被ストッパ面７５とが係合するため、振動溶着の際に、振動体２ｆの矢印Ｋ１，Ｋ２方向への取付盤７ｆの振動が規制される。従って、振動体２ｆの振動が取付盤７ｆに伝搬されるとしても、振動ユニット９ｆの取付盤７ｆに対する固定性を高めることができる。加えて本実施例によれば、図５に示すように、振動ユニット９ｆを基部１の固定面１０に固定する油圧シリンダ装置１０３は振動体２ｆの振動方向である矢印Ｋ１，Ｋ２方向に複数個並設されている。このため振動体２ｆの振動が振動ユニット９ｆの取付盤７ｆに伝搬されるとしても、振動ユニット９ｆの取付盤７ｆに対する固定性、拘束性を高めることができる。   Further, since the stopper surface 15 of the base 1 and the stoppered surface 75 of the mounting plate 7f are engaged, vibration of the mounting plate 7f in the directions of arrows K1 and K2 of the vibrating body 2f is restricted during vibration welding. . Therefore, even if the vibration of the vibrating body 2f is propagated to the mounting board 7f, the fixability of the vibration unit 9f to the mounting board 7f can be improved. In addition, according to the present embodiment, as shown in FIG. 5, there are a plurality of hydraulic cylinder devices 103 for fixing the vibration unit 9f to the fixed surface 10 of the base 1 in the directions of arrows K1 and K2, which are the vibration directions of the vibration body 2f. It is installed side by side. For this reason, even if the vibration of the vibrating body 2f is propagated to the mounting plate 7f of the vibrating unit 9f, it is possible to improve the fixing and restraining properties of the vibrating unit 9f with respect to the mounting plate 7f.

また、ワークＷｆについて振動溶着の第１工程を実施する場合について説明する。この場合、図８から理解できるように、第１下ワーク保持部６ｆが図略の昇降シリンダ装置により矢印Ｙ１方向に上昇し、ワークＷｆが第１上ワーク保持部５ｆと第１下ワーク保持部６ｆとで挟持される。この状態で、加振源３に交流の励磁電流が通電される。すると前述したように、第１振動ユニット９ｆの第１振動体２ｆは横方向に往復振動する。第１振動体２ｆの振動は第１振動ユニット９ｆの第１上ワーク保持部５ｆに伝播される。これによりワークＷｆを構成する複数の部品が摩擦熱に基づいて互いに振動溶着されて接合される。   A case where the first step of vibration welding is performed on the workpiece Wf will be described. In this case, as can be understood from FIG. 8, the first lower work holding portion 6f is raised in the direction of the arrow Y1 by a lifting cylinder device (not shown), and the work Wf is moved to the first upper work holding portion 5f and the first lower work holding portion. 6f. In this state, an alternating excitation current is applied to the excitation source 3. Then, as described above, the first vibrating body 2f of the first vibrating unit 9f reciprocates in the lateral direction. The vibration of the first vibrating body 2f is propagated to the first upper work holding portion 5f of the first vibrating unit 9f. Thereby, a plurality of parts constituting the work Wf are vibration welded to each other based on the frictional heat and joined.

次に、ワークＷｓについて振動溶着の第２工程を実施する場合について説明する。この場合、図８から理解できるように、振動ユニットアクチェエータ５００ｍを矢印Ｘ１方向に前進駆動させる。これにより第１振動ユニット９ｆおよび第２振動ユニット９ｓを振動ユニット案内部６００に沿って矢印Ｘ１方向に向けて移動させる。これにより第２振動ユニット９ｓと加振源３とが対面する。   Next, the case where the 2nd process of vibration welding is implemented about the workpiece | work Ws is demonstrated. In this case, as can be understood from FIG. 8, the vibration unit actuator 500m is driven forward in the direction of the arrow X1. Thus, the first vibration unit 9f and the second vibration unit 9s are moved along the vibration unit guide portion 600 in the direction of the arrow X1. As a result, the second vibration unit 9s and the excitation source 3 face each other.

第２工程では、第２下ワーク保持部６ｓが図略の昇降シリンダ装置により矢印Ｙ１方向に上昇し、ワークＷｓは第２上ワーク保持部５ｓと第２下ワーク保持部６ｓとで挟持されている。この状態で、加振源３に交流の励磁電流が通電される。すると前述したように、第２振動ユニット９ｓの第２振動体２ｓは矢印Ｋ１，Ｋ２方向（横方向）に往復振動する。第２振動体２ｓの振動は第２振動ユニット９ｓの第２上ワーク保持部５ｓに伝播される。これによりワークＷｓを構成する複数の部品が摩擦熱に基づいて互いに振動溶着される。   In the second step, the second lower work holding part 6s is raised in the direction of the arrow Y1 by a lifting cylinder device (not shown), and the work Ws is held between the second upper work holding part 5s and the second lower work holding part 6s. Yes. In this state, an alternating excitation current is applied to the excitation source 3. Then, as described above, the second vibrating body 2s of the second vibrating unit 9s reciprocates in the directions of arrows K1 and K2 (lateral direction). The vibration of the second vibrating body 2s is propagated to the second upper work holding portion 5s of the second vibrating unit 9s. As a result, the plurality of parts constituting the workpiece Ws are vibration welded to each other based on the frictional heat.

以上説明したように本実施例によれば、振動溶着の第１工程を実施する第１振動ユニット９ｆと振動溶着の第２工程を実施する第２振動ユニット９ｓとは、基部１の固定面１０に並設状態に設けられている。これにより振動溶着の生産性を高めるのに有利となる。そして、振動ユニットアクチェエータ５００ｍにより第１振動ユニット９ｆ及び第２振動ユニット９ｓをレール状の振動ユニット案内部６００に沿って移動させ、加振源３に対面させることができる。このため加振源３を複数設けずとも良く、設備費の低減に有利となる。なお振動ユニット９ｆ，９ｓをスライド移動させるとき、スライド移動性を確保するため、油圧シリンダ装置１０３の締め付け用の油圧室１０４の圧力を緩め、第１振動ユニット９ｆの第１取付盤７ｆと基部１の固定面１０との間に隙間を形成したり、第２振動ユニット９ｓの第２取付盤７ｓと基部１の固定面１０との間に隙間を形成しておくことが好ましい。   As described above, according to the present embodiment, the first vibration unit 9 f that performs the first step of vibration welding and the second vibration unit 9 s that performs the second step of vibration welding include the fixed surface 10 of the base 1. Are provided in parallel. This is advantageous for improving the productivity of vibration welding. The first vibration unit 9 f and the second vibration unit 9 s can be moved along the rail-shaped vibration unit guide 600 by the vibration unit actuator 500 m so as to face the vibration source 3. For this reason, it is not necessary to provide a plurality of vibration sources 3, which is advantageous for reducing the equipment cost. Note that when the vibration units 9f and 9s are slid, the pressure in the hydraulic chamber 104 for tightening the hydraulic cylinder device 103 is relaxed to ensure slide mobility, and the first mounting plate 7f and the base 1 of the first vibration unit 9f. It is preferable to form a gap between the fixed surface 10 and the second mounting plate 7 s of the second vibration unit 9 s and the fixed surface 10 of the base 1.

また本実施例によれば、第１振動体２ｆ、第１上ワーク保持部５ｆ、第１弾性部材４ｆ、第１取付盤７ｆは一体的化され、第１振動ユニット９ｆとされている。第１振動ユニット９ｆを構成する第１取付盤７ｆのうち、基部１の固定面１０に対面する面、つまり、第１上ワーク保持部５ｆと反対側に位置する上面は、振動溶着機の基部１に着脱交換可能に取り付けられる第１着脱分離面９０ｆとされている。第１振動ユニット９ｆの第１着脱分離面９０ｆは、第１上ワーク保持部５ｆと反対側に位置している。このため第１振動体２ｆが振動し、その振動が第１上ワーク保持部５ｆに伝播されたとしても、第１振動ユニット９ｆの第１着脱分離面９０ｆへの振動伝播は抑制されている。このため振動溶着の際に第１振動ユニット９ｆの第１着脱分離面９０ｆに摩耗、焼付等といった不具合が発生することが抑制される。故に、第１振動ユニット９ｆの第１着脱分離面９０ｆを振動溶着機に取り付ける取付精度の信頼性を高めることができ、振動溶着の高精度化、高品質化に貢献できる。   Further, according to the present embodiment, the first vibrating body 2f, the first upper work holding portion 5f, the first elastic member 4f, and the first mounting board 7f are integrated into a first vibrating unit 9f. Of the first mounting plate 7f constituting the first vibration unit 9f, the surface facing the fixed surface 10 of the base 1, that is, the upper surface located on the side opposite to the first upper work holding portion 5f is the base of the vibration welder. 1 is a first detachable separation surface 90f that is detachably attached. The first attachment / detachment separation surface 90f of the first vibration unit 9f is located on the side opposite to the first upper work holding portion 5f. For this reason, even if the 1st vibrating body 2f vibrates and the vibration is propagated to the 1st upper workpiece holding part 5f, the vibration propagation to the 1st attachment / detachment separation surface 90f of the 1st vibration unit 9f is suppressed. For this reason, the occurrence of problems such as wear and seizure on the first attachment / detachment separation surface 90f of the first vibration unit 9f during vibration welding is suppressed. Therefore, the reliability of the attachment accuracy for attaching the first attachment / detachment separation surface 90f of the first vibration unit 9f to the vibration welding machine can be increased, and this can contribute to the high accuracy and high quality of vibration welding.

同様に、第２振動体２ｓ、第２上ワーク保持部５ｓ、第２弾性部材４ｓ、第２取付盤７ｓは一体的化され、第２振動ユニット９ｓとされている。そして、第２振動ユニット９ｓを構成する第２取付盤７ｓのうち、基部１の固定面１０に対面する面、つまり第２上ワーク保持部５ｓと反対側に位置する面を、第２着脱分離面９０ｓとしている。そして第２振動ユニット９ｓの第２着脱分離面９０ｓは、第２ワーク保持部ｓと反対側に位置している。このため第２振動体２ｓが振動し、その振動が第２上ワーク保持部５ｓに伝播されたとしても、第２振動ユニット９ｓの第２着脱分離面９０ｓへの振動伝播は抑制されている。このため振動溶着の際に第２振動ユニット９ｓの第２着脱分離面９０ｓに摩耗、焼付等といった不具合が発生することが抑制される。故に、第２振動ユニット９ｓの第２着脱分離面９０ｓを振動溶着機に取り付ける取付精度の信頼性を高めることができ、振動溶着の精度、高品質化に貢献できる。   Similarly, the second vibrating body 2s, the second upper work holding portion 5s, the second elastic member 4s, and the second mounting plate 7s are integrated into a second vibrating unit 9s. Of the second mounting plate 7s constituting the second vibration unit 9s, the surface facing the fixed surface 10 of the base portion 1, that is, the surface located on the opposite side to the second upper work holding portion 5s is second attached and detached. The surface is 90s. The second attachment / detachment separation surface 90s of the second vibration unit 9s is located on the side opposite to the second workpiece holding part s. For this reason, even if the 2nd vibrating body 2s vibrates and the vibration is propagated to the 2nd upper workpiece holding part 5s, the vibration propagation to the 2nd attachment / detachment separation surface 90s of the 2nd vibration unit 9s is suppressed. For this reason, the occurrence of problems such as wear and seizure on the second detachable separation surface 90s of the second vibration unit 9s during vibration welding is suppressed. Therefore, the reliability of the attachment accuracy for attaching the second detachable separation surface 90s of the second vibration unit 9s to the vibration welding machine can be increased, and this can contribute to the accuracy and quality of vibration welding.

図１１〜図１３は実施例３を示す。本実施例は実施例１と基本的には同様の構成、作用効果を有する。共通の機能を奏する部位には共通の符号を付する。以下、実施例１と相違する部位を中心として説明する。本実施例は、固定手段としての油圧シリンダ装置１０３について改良している。油圧シリンダ装置１０３は、締め付け用の油圧室１０４と、離脱用の油圧室１０５と、油圧室１０４，１０５を備えるシリンダ１０６と有する。締め付け用の油圧室１０４は、クランプ１０２と凹状の被係合部１０１との係合力を増加させる方向に、クランプ１０２を上方（矢印Ｙ１方向）に付勢する油圧を供給する。図１１に示すように、クランプ１０２は、凸部１１４と、凸部１１４に繋がる軸部１１５と、軸部１１５に繋がるピストン１１６とを有する。ピストン１１６は、シリンダ１０６から露出する回動操作部１１６ｘを有すると共に、油圧シリンダ装置１０３のシリンダ１０６内を油圧室１０４と油圧室１０５とに区画する。ここで、凸部１１４は、図１１に示すように、第２傾斜面１１３ではなくピストン１１６の中心軸心ＰＢに沿った直状面１１８を有する。凸部１１４は、図１２に示すように、中心軸心ＰＢの回りで所定の角度（例えば９０度）回動すると、下方（矢印Ｙ２方向）に向かうにつれて拡開する第２傾斜面１１３を発現させる。   11 to 13 show a third embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. The parts having common functions are denoted by common reference numerals. Hereinafter, a description will be given centering on parts different from the first embodiment. In this embodiment, the hydraulic cylinder device 103 as a fixing means is improved. The hydraulic cylinder device 103 includes a hydraulic chamber 104 for tightening, a hydraulic chamber 105 for detachment, and a cylinder 106 including the hydraulic chambers 104 and 105. The clamping hydraulic chamber 104 supplies hydraulic pressure that urges the clamp 102 upward (in the direction of the arrow Y1) in a direction that increases the engagement force between the clamp 102 and the recessed engaged portion 101. As shown in FIG. 11, the clamp 102 includes a convex portion 114, a shaft portion 115 connected to the convex portion 114, and a piston 116 connected to the shaft portion 115. The piston 116 has a rotation operation unit 116 x exposed from the cylinder 106 and partitions the inside of the cylinder 106 of the hydraulic cylinder device 103 into a hydraulic chamber 104 and a hydraulic chamber 105. Here, as shown in FIG. 11, the convex portion 114 has a straight surface 118 along the central axis PB of the piston 116 instead of the second inclined surface 113. As shown in FIG. 12, the convex portion 114 develops a second inclined surface 113 that expands downward (in the direction of the arrow Y <b> 2) when rotated by a predetermined angle (for example, 90 degrees) around the central axis PB. Let

前記した振動ユニット９ｆ，９ｓを基部１の固定面１０に固定させるときには、振動ユニット９ｆ，９ｓの取付盤７ｆ，７ｓの着脱分離面９０ｆ，９０ｓを基部１の固定面１０に対面させつつ、振動ユニット９ｆ，９ｓを矢印Ｙ１方向（基部１の固定面１０の法線方向）に持ち上げ、取付盤７ｆ，７ｓの凹状の被係合部１０１に凸部１１４を嵌める（図１１参照）。この場合、図１１に示すように、凹状の被係合部１０１の第１傾斜面１１０と凸部１１４の直状面１１８とが対面するものの、凹状の被係合部１０１の第１傾斜面１１０と凸部１１４の第２傾斜面１１３とが干渉しないため、振動ユニット９ｆ，９ｓを矢印Ｙ１方向（基部１の固定面１０の法線方向）に持ち上げれば良い。その後、ピストン１１６をこれの中心軸心ＰＢの回りで矢印Ｐ４方向に約９０度回動させ、図１２に示すように、凹状の被係合部１０１の第１傾斜面１１０と凸部１１４の第２傾斜面１１３とを係合させる。その後、油圧室１０４に油を供給すると共に油圧室１０５の油を吐出させると、ピストン１１６が上方（矢印Ｙ１方向）に付勢される。この結果、振動ユニット９ｆ，９ｓの取付盤７ｆ，７ｓが基部１の固定面１０に固定され、振動ユニット９ｆ，９ｓの取付盤７ｆ，７ｓの着脱分離面９０ｆ，９０ｓは基部１の固定面１０に密着する。   When fixing the vibration units 9f and 9s to the fixed surface 10 of the base 1, the vibration units 9f and 9s are vibrated while the attachment / detachment separation surfaces 90f and 90s of the mounting plates 7f and 7s face the fixed surface 10 of the base 1. The units 9f and 9s are lifted in the direction of the arrow Y1 (the normal direction of the fixed surface 10 of the base 1), and the convex portions 114 are fitted into the concave engaged portions 101 of the mounting boards 7f and 7s (see FIG. 11). In this case, as shown in FIG. 11, the first inclined surface 110 of the concave engaged portion 101 faces the first inclined surface 110 of the concave engaged portion 101 and the straight surface 118 of the convex portion 114. 110 and the second inclined surface 113 of the convex portion 114 do not interfere with each other, and the vibration units 9f and 9s may be lifted in the direction of arrow Y1 (the normal direction of the fixed surface 10 of the base 1). Thereafter, the piston 116 is rotated about 90 degrees in the direction of the arrow P4 around the center axis PB of the piston 116, and as shown in FIG. 12, the first inclined surface 110 and the convex portion 114 of the concave engaged portion 101 are rotated. The second inclined surface 113 is engaged. Thereafter, when oil is supplied to the hydraulic chamber 104 and the oil in the hydraulic chamber 105 is discharged, the piston 116 is biased upward (in the direction of arrow Y1). As a result, the mounting plates 7f and 7s of the vibration units 9f and 9s are fixed to the fixed surface 10 of the base 1, and the attachment / detachment separation surfaces 90f and 90s of the mounting plates 7f and 7s of the vibration units 9f and 9s are fixed to the fixed surface 10 of the base 1. Close contact with.

図１４〜図１６は実施例４を示す。本実施例は実施例１と基本的には同様の構成、作用効果を有する。共通の機能を奏する部位には共通の符号を付する。以下、実施例１と相違する部位を中心として説明する。本実施例によれば、第１振動ユニット９ｆ，第２振動ユニット９ｓは可動式ではなく、基部１の固定面１０の定位置に固定されており、矢印Ｘ１，Ｘ２方向において並設されている。可動式の加振源３を加振源案内部３５に沿って第１振動ユニット９ｆ及び第２振動ユニット９ｓ間において移動させる。このため、加振源３は第１振動ユニット９ｆ及び第２振動ユニット９ｓの双方に共通化されている。よって加振源３を複数設けずとも良く、設備費の低減に有利となる。加振源アクチェエータ３００により可動式の加振源３を加振源案内部３５に沿って移動させるため、移動操作が容易である。なお本実施例によれば、図１７に示す従来技術と同様な締結構造により、第１振動ユニット９ｆ，第２振動ユニット９ｓは基部１に固定されている。   14 to 16 show a fourth embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. The parts having common functions are denoted by common reference numerals. Hereinafter, a description will be given centering on parts different from the first embodiment. According to the present embodiment, the first vibration unit 9f and the second vibration unit 9s are not movable, but are fixed at fixed positions on the fixed surface 10 of the base 1, and are arranged in parallel in the directions of the arrows X1 and X2. . The movable excitation source 3 is moved along the excitation source guide 35 between the first vibration unit 9f and the second vibration unit 9s. For this reason, the excitation source 3 is shared by both the first vibration unit 9f and the second vibration unit 9s. Therefore, it is not necessary to provide a plurality of excitation sources 3, which is advantageous for reducing the equipment cost. Since the movable excitation source 3 is moved along the excitation source guide 35 by the excitation source actuator 300, the moving operation is easy. According to the present embodiment, the first vibration unit 9f and the second vibration unit 9s are fixed to the base 1 by a fastening structure similar to that of the prior art shown in FIG.

（他の実施例）振動溶着は第１工程と第２工程とからなるものでも良いし、あるいは、第１工程と第２工程と第３工程とからなるものでも良い。この場合、第３工程用の振動ユニットを並設させることが好ましい。上記した各実施例によれば、加振源３または振動ユニット９ｆ，９ｓは横方向に沿って移動可能とされているが、これに限らず、場合によっては、縦方向に沿って移動させる形態としても良い。その他、本発明は上記した且つ図面に示した実施例のみに限定されるものではなく、要旨を逸脱しない範囲内で適宜変更して実施できるものである。   (Other Embodiments) Vibration welding may consist of the first step and the second step, or may consist of the first step, the second step and the third step. In this case, it is preferable to arrange the vibration units for the third step in parallel. According to each of the embodiments described above, the excitation source 3 or the vibration units 9f and 9s are movable along the horizontal direction. However, the present invention is not limited to this, and depending on the case, it may be moved along the vertical direction. It is also good. In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within a range not departing from the gist.
