【産業上の利用分野】[Industrial applications]

この考案は、自動車用内装部品の基材に樹脂成形体をカシメ固定する超音波カ シメ装置に関する。 The present invention relates to an ultrasonic caulking device for caulking and fixing a resin molding on a base material of an automobile interior part.

【０００２】[0002]

【従来の技術】[Prior Art]

図２は自動車室内に設置されるドアトリム１を示すもので、このドアトリム１ の表面所定箇所には、ドアポケット２等の樹脂成形体が装着されている。 FIG. 2 shows a door trim 1 installed in a vehicle interior, and a resin molding such as a door pocket 2 is attached to a predetermined portion of the surface of the door trim 1.

【０００３】 そして、ドアポケット２をドアトリム１に取付ける取付構造は、ドアポケット ２の裏面に取付用ボス部を突設形成し、ドアトリム１の取付孔内に挿入した後、 プッシュナットを係着するか、あるいはビス締め等の方式が従来から採用されて いる。In the mounting structure for mounting the door pocket 2 on the door trim 1, a mounting boss portion is projectingly formed on the back surface of the door pocket 2 and inserted into the mounting hole of the door trim 1, and then a push nut is attached. Alternatively, a method such as screw tightening has been conventionally used.

【０００４】 さらに、最近では部品点数の削減およびコストダウンを図るため、図３に示す ように超音波カシメ装置を利用して、ドアポケット２の裏面に設けた取付用ボス 部２ａの先端部分をカシメ固定する方法が多く採用されつつある。Further, recently, in order to reduce the number of parts and cost, an ultrasonic caulking device as shown in FIG. 3 is used to remove the tip portion of the mounting boss portion 2 a provided on the back surface of the door pocket 2. Many methods of fixing by crimping are being adopted.

【０００５】 この超音波カシメ装置３を使用してドアポケット２をドアトリム１に固定する 方法について簡単に説明すると、まず、受け治具４上にドアポケット２およびド アトリム１を載置する。このとき、ドアポケット２の取付用ボス部２ａはドアト リム１の取付孔１ａ内に挿入され、取付用ボス部２ａの先端が所定量ドアトリム １の裏面から上方に突出している。A method of fixing the door pocket 2 to the door trim 1 using the ultrasonic caulking device 3 will be briefly described. First, the door pocket 2 and the door trim 1 are placed on the receiving jig 4. At this time, the mounting boss portion 2a of the door pocket 2 is inserted into the mounting hole 1a of the door trim 1, and the tip of the mounting boss portion 2a projects upward from the rear surface of the door trim 1 by a predetermined amount.

【０００６】 この超音波カシメ装置３は、取付用ボス部２ａ先端を超音波振動を加えながら 押圧する超音波ホーン５と、この超音波ホーン５を上下動させる駆動用シリンダ ６と、超音波ホーン５を所定の下方位置で停止させるためのセンサ７とを備えて おり、このセンサ７は受け治具４に設けたストッパ８に到達したのを検知して、 超音波ホーン５が停止する構成になっている。The ultrasonic caulking device 3 includes an ultrasonic horn 5 that presses the tip of the mounting boss 2 a while applying ultrasonic vibration, a drive cylinder 6 that vertically moves the ultrasonic horn 5, and an ultrasonic horn. 5 is provided with a sensor 7 for stopping at a predetermined lower position, and the sensor 7 detects that the stopper 8 provided on the receiving jig 4 is reached, and the ultrasonic horn 5 is stopped. Has become.

【０００７】 すなわち、従来の超音波カシメ装置３は、超音波ホーン５の停止位置が、受け 治具４を基準として設定されている。That is, in the conventional ultrasonic caulking device 3, the stop position of the ultrasonic horn 5 is set with reference to the receiving jig 4.

【０００８】[0008]

【考案が解決しようとする課題】[Problems to be solved by the device]

このように、従来の超音波カシメ装置３は、超音波ホーン５のストロークを決 定するセンサ７は、受け治具４を基準として、設置されている関係で、ドアトリ ム１の芯材１ｂおよび表皮材１ｃの板厚のバラツキあるいはドアポケット２およ びドアトリム１を受け治具４上にセットする際のセットバラツキ等があった場合 、これらのバラツキを吸収することができない。 As described above, in the conventional ultrasonic caulking device 3, the sensor 7 for determining the stroke of the ultrasonic horn 5 is installed with the receiving jig 4 as a reference. If there are variations in the plate thickness of the skin material 1c or variations in the setting when the door pocket 2 and the door trim 1 are set on the jig 4, the variations cannot be absorbed.

【０００９】 例えば、ドアトリム１の板厚が薄い場合には、図４に示すように、ドアトリム １の裏面と超音波ホーン５の先端部との間の距離が大きくなるため、取付用ボス 部２ａ先端は充分なカシメ加工が行なわれず、ドアポケット２の脱落が生じる等 の不具合がある。For example, when the plate thickness of the door trim 1 is thin, as shown in FIG. 4, the distance between the rear surface of the door trim 1 and the tip of the ultrasonic horn 5 becomes large, so that the mounting boss 2 a There is a problem that the tip is not sufficiently caulked and the door pocket 2 falls off.

【００１０】 逆に、ドアトリム１の板厚が厚い場合には、図５に示すように、ドアトリム１ の裏面と超音波ホーン５の先端部との間にはわずかな隙間しか残らないため、取 付用ボス部２ａの先端部分は極度に偏平化し、カシメ強度が得られないという不 具合がある。On the other hand, when the door trim 1 has a large plate thickness, as shown in FIG. 5, there is only a slight gap between the rear surface of the door trim 1 and the tip of the ultrasonic horn 5, and therefore, the clearance is small. The tip portion of the attachment boss portion 2a is extremely flattened, and there is a problem that the crimping strength cannot be obtained.

【００１１】 本考案は、このような事情に鑑みてなされたもので、本考案の目的とするとこ ろは、内装基材に樹脂成形体を取付用ボス部の先端部をカシメ固定して取付ける 超音波カシメ装置において、内装基材の板厚バラツキやセットバラツキがあって も、超音波ホーンの先端部分を常に適切位置に位置決めでき、強固なカシメ強度 が得られる超音波カシメ装置を提供することにある。The present invention has been made in view of the above circumstances, and an object of the present invention is to mount a resin molded body on an interior base material by caulking the tip portion of a mounting boss portion. Provided is an ultrasonic caulking device that can always position the tip of the ultrasonic horn at an appropriate position even if there are variations in the thickness of the interior base material or variations in the set in the ultrasonic caulking device. It is in.

【００１２】[0012]

【課題を解決するための手段】 上記目的を達成するために、本考案は、内装基材の表面に樹脂成形体を装着し 、内装基材の取付孔内に樹脂成形体の裏面に突設した取付用ボス部を挿入し、こ の取付用ボス部先端を超音波加工によりカシメ固定する超音波カシメ装置におい て、 前記超音波カシメ装置は、取付用ボス部先端を押圧する超音波ホーンと、この 超音波ホーンを一定ストロークで上下動させる駆動用シリンダと、この駆動用シ リンダのストローク量を規制するセンサとを備え、上記センサは、内装基材の裏 面を基準点としてこの基準点の上方所定位置で超音波ホーン先端を停止させるよ うに設定されていることを特徴とする。[Means for Solving the Problems] In order to achieve the above object, the present invention provides a resin molded body mounted on the surface of an interior base material, and protruding on the back surface of the resin molded body in a mounting hole of the interior base material. In the ultrasonic caulking device that inserts the mounting boss part and fixes the mounting boss end by caulking by ultrasonic machining, the ultrasonic caulking device is an ultrasonic horn that presses the mounting boss end. It is equipped with a drive cylinder that moves the ultrasonic horn up and down with a constant stroke, and a sensor that regulates the stroke amount of this drive cylinder.The sensor uses the back surface of the interior base material as a reference point. It is set so that the tip of the ultrasonic horn is stopped at a predetermined position above.

【００１３】[0013]

【作用】[Action]

以上の構成から明らかなように、超音波ホーンのストロークを決定するセンサ は、ドアトリム等の内装基材の裏面を基準点として設定されているため、超音波 ホーンの先端部分は、常に内装基材の裏面の上方所定箇所に停止する。 As is clear from the above configuration, the sensor that determines the stroke of the ultrasonic horn is set with the back surface of the interior base material such as the door trim as the reference point, so the tip of the ultrasonic horn is always the interior base material. Stop at a predetermined location above the back surface of the.

【００１４】 したがって、内装基材の板厚バラツキ、セットバラツキがあった場合でも、超 音波ホーンのストローク量が可変して、適切位置で超音波ホーン先端部が停止し 、良好なカシメ加工がなされることになる。Therefore, even if there are variations in the thickness of the interior base material and variations in the set, the stroke amount of the ultrasonic horn is changed, the tip of the ultrasonic horn stops at an appropriate position, and good caulking is performed. Will be.

【００１７】 図１において、超音波カシメ装置１０は、先端部に位置する超音波ホーン１１ と、この超音波ホーン１１を所定ストローク量上下動させる駆動用シリンダ１２ と、ブラケット１３を介して鉛直方向に支持される支持部材１４と、支持部材１ ４の下端に設置されるセンサ１５とから構成されている。In FIG. 1, an ultrasonic caulking device 10 includes an ultrasonic horn 11 located at a tip portion, a drive cylinder 12 for vertically moving the ultrasonic horn 11 by a predetermined stroke amount, and a vertical direction via a bracket 13. And a sensor 15 installed at the lower end of the support member 14.

【００１８】 次いで、本考案による超音波カシメ装置１０を使用してドアトリム３０にドア ポケット４０をカシメ固定する作業について説明する。Next, the work of caulking and fixing the door pocket 40 to the door trim 30 using the ultrasonic caulking device 10 according to the present invention will be described.

【００１９】 まず、受け治具２０の型面にドアポケット４０およびドアトリム３０をセット する。First, the door pocket 40 and the door trim 30 are set on the die surface of the receiving jig 20.

【００２０】 このとき、ドアポケット４０の裏面に突設されている取付用ボス部４１をドア トリム３０の取付孔３１内に挿入して、取付用ボス部４１の先端部分をドアトリ ム３０の裏面から突出させた状態にしておく。At this time, the mounting boss portion 41 protruding from the back surface of the door pocket 40 is inserted into the mounting hole 31 of the door trim 30, and the tip portion of the mounting boss portion 41 is attached to the back surface of the door trim 30. Keep it protruding from.

【００２１】 次いで、超音波カシメ装置１０を使用して、取付用ボス部４１の先端部分をカ シメ加工を行なう。Next, the ultrasonic caulking device 10 is used to caulk the tip portion of the mounting boss portion 41.

【００２２】 まず、駆動用シリンダ１２が作動して超音波ホーン１１の先端部分が取付用ボ ス部４１の先端に当接し、この超音波ホーン１１から超音波振動を加えつつ押圧 して、取付用ボス部４１の先端部分を溶融かつ加圧して、アンカー形状に加工を 行なう。First, the driving cylinder 12 operates to bring the tip of the ultrasonic horn 11 into contact with the tip of the mounting boss 41. The ultrasonic horn 11 presses the ultrasonic horn 11 while applying ultrasonic vibration. The tip portion of the working boss portion 41 is melted and pressed to be processed into an anchor shape.

【００２３】 ところで、本考案の特徴は、超音波ホーン１１のストローク量を調整するセン サ１５の検知対象として、ドアトリム３０の裏面を基準点に設定したことにある 。By the way, a feature of the present invention is that the back surface of the door trim 30 is set as a reference point as a detection target of the sensor 15 for adjusting the stroke amount of the ultrasonic horn 11.

【００２４】 すなわち、駆動用シリンダ１２の作動により超音波ホーン１１が下降して、ド アポケット４０の取付用ボス部４１先端部分に対してカシメ加工を行なうが、セ ンサ１５がドアトリム３０の芯材３２裏面に到達したとき、センサ１５が作動し 、駆動用シリンダ１２の駆動が停止して超音波ホーン１１がその地点で停止する という構成である。That is, the ultrasonic horn 11 descends due to the operation of the driving cylinder 12, and the tip portion of the mounting boss portion 41 of the door pocket 40 is caulked, but the sensor 15 does not move the core of the door trim 30. When the back surface of the material 32 is reached, the sensor 15 is activated, the driving of the driving cylinder 12 is stopped, and the ultrasonic horn 11 is stopped at that point.

【００２５】 したがって、超音波ホーン１１の先端部分はドアトリム３０の芯材３２裏面か ら所定寸法（図１中ｄで示す）上方位置で常に停止することになる。Therefore, the tip portion of the ultrasonic horn 11 is always stopped at a position above the back surface of the core material 32 of the door trim 30 by a predetermined dimension (indicated by d in FIG. 1).

【００２６】 よって、ドアトリム３０の芯材３２および表皮材３３の厚みにバラツキが生じ た場合でも、これらのバラツキに影響を受けることがなく、超音波ホーン１１が 常に適切位置で停止するため、従来のように充分なカシメ加工が行なわれないと ともに、過度のカシメ加工によりカシメ強度が不足する等の不具合がなくなり、 規定のアンカー形状を備えた良好なカシメ加工が可能となる。Therefore, even if the thicknesses of the core material 32 and the skin material 33 of the door trim 30 are varied, the variation is not affected and the ultrasonic horn 11 is always stopped at an appropriate position. As described above, insufficient caulking is not performed, and problems such as insufficient caulking strength due to excessive caulking are eliminated, and good caulking with a prescribed anchor shape is possible.

【００２７】 以上説明した実施例は、ドアトリム３０にドアポケット４０をカシメ固定する 作業に本考案の超音波カシメ装置１０を使用した実施例であるが、ドアポケット ４０に限定されることはなく、取付用ボス部を介して内装基材にカシメ固定され るものであれば、特にその用途に限定を加えるものではない。Although the embodiment described above is an embodiment in which the ultrasonic caulking device 10 of the present invention is used for the work of caulking the door pocket 40 to the door trim 30, the invention is not limited to the door pocket 40. The application is not particularly limited as long as it is caulked and fixed to the interior base material via the mounting boss portion.

【考案の効果】[Effect of the device]

以上説明した通り、本考案による超音波カシメ装置は、超音波ホーンのストロ ーク量を制御するセンサは、従来の受け治具を基準点とするのではなく、被加工 部材である内装基材裏面を基準点として超音波ホーンのストローク量を調整する という構成であるため、内装基材の板厚バラツキやセットバラツキがあった場合 でも、取付用ボス先端部分のアンカー形状が常に一定なものとなり、良好なカシ メ加工による強固な取付が可能となり、内装基材から樹脂成形体が脱落すること が可及的に防止でき、長期にわたり良好な取付安定性が得られるという効果を有 する。 As described above, in the ultrasonic caulking device according to the present invention, the sensor for controlling the stroke amount of the ultrasonic horn does not use the conventional receiving jig as the reference point, but the interior base material that is the member to be processed. Since the stroke amount of the ultrasonic horn is adjusted using the back surface as a reference point, the anchor shape at the tip of the mounting boss will always be the same even if there are variations in the thickness of the interior base material or variations in the set. As a result, it is possible to perform strong caulking for firm mounting, to prevent the resin molded body from falling off the interior base material as much as possible, and to obtain good mounting stability for a long period of time.
