Description

本発明は、ＡＢＳやポリスチレン（ＰＳ）、ポリプロピレン（ＰＰ）等の熱可塑性樹脂からなる円筒形状の加工物を付熱状態で加圧することにより所定形状に塑性変形させて前記円筒形状の加工物の内側に配置された部品を固定する場合等に用いられる熱カシメ装置の位置決め調節治具および調節方法に関するものである。   In the present invention, a cylindrical workpiece made of a thermoplastic resin such as ABS, polystyrene (PS), polypropylene (PP), or the like is plastically deformed into a predetermined shape by pressurizing in a heated state, and the cylindrical workpiece is obtained. The present invention relates to a positioning adjustment jig and an adjustment method of a thermal caulking device used when fixing components arranged on the inside.

従来熱カシメ装置ではカシメ作業に先立って、加工物を加圧し変形させるヒーターチップと加工物の位置合わせを行うことは既に知られている。加工物の先端を押しつぶすことによって塑性変形させる場合には、ヒーターチップの位置に対する加工物の位置はさほど厳しい精度を必要としないが、光学部品など精密な精度を必要とするものの場合は、精度の高い位置合わせが求められ、またレンズ枠にレンズを固定する場合は、押しつぶす部分がリング状となるため、中心位置合わせだけでなく、平面平行性も確保しなければならない。（下記特許文献１参照）。
特許第３６９４５８６号公報 In a conventional heat caulking device, prior to caulking work, it is already known to align the work piece with a heater chip that pressurizes and deforms the work piece. When plastic deformation is performed by crushing the tip of the work piece, the position of the work piece relative to the position of the heater chip does not require very strict accuracy, but in the case of precision parts such as optical parts that require high precision, When a high alignment is required and the lens is fixed to the lens frame, the portion to be crushed becomes a ring shape, so that not only the center alignment but also the plane parallelism must be ensured. (See Patent Document 1 below).
Japanese Patent No. 3694586

この場合のヒーターチップと加工物の位置合わせについて、図１および図２によって説明する。   The positioning of the heater chip and the workpiece in this case will be described with reference to FIGS.

熱カシメ装置の上方に設けられ上下に稼動し加工物に圧力を加えるヘッド２には、熱部４に熱を与えるためのヒーター６と、このヒーター６によって発生する熱を蓄える蓄熱部４が設けられ、前記蓄熱部４の下面にはヒーターチップ８が取外し可能なようにボルト４０にて取付けられている。   A head 2 provided above the heat caulking device and operating up and down to apply pressure to the workpiece is provided with a heater 6 for applying heat to the heat unit 4 and a heat storage unit 4 for storing heat generated by the heater 6. The heater chip 8 is attached to the lower surface of the heat storage unit 4 with bolts 40 so as to be removable.

熱カシメ装置の下方に設置されている機械テーブル１４の上に治具用ベース１２が置かれ、その中心には位置決め用ボス１２ａが設けられている。この位置決め用ボス１２ａが前記ヒーターチップ８と同芯となるように、前記治具用ベース１２は調節されボルト４２によって固定されている。前記治具用ベース１２には熱カシメ加工が施される加工物を載せる受け台１０がボルト４４によって固定されている。   A jig base 12 is placed on a machine table 14 installed below the heat caulking device, and a positioning boss 12a is provided at the center thereof. The jig base 12 is adjusted and fixed by bolts 42 so that the positioning boss 12a is concentric with the heater chip 8. A cradle 10 on which a workpiece to be heat caulked is placed is fixed to the jig base 12 by bolts 44.

まず前記加工物の受け台１０の位置調節を行うが、前記ヒーターチップ８の中心と前記加工物の受け台１０の中心の位置を合わせるとき、前記ヒーターチップ８を取付けた状態で行うことが出来ないので、前記ヒーターチップ８を前記蓄熱部４から取外し、芯出し治具Ａ２４をボルト４４にて取付け、前記加工物の受け台１０を取外し、芯出し治具Ｂ２６を取付け、前記ヘッド２を下降させて前記芯出し治具Ａ２４と前記芯出し治具Ｂ２６を合わせる。この時、前記治具用ベース１２を前記機械テーブル１４に固定するボルト４４は緩めておき、芯合わせを行った後で締め付ける。   First, the position of the workpiece cradle 10 is adjusted. When the center of the heater chip 8 and the center of the workpiece cradle 10 are aligned, the heater chip 8 can be attached. Therefore, the heater chip 8 is removed from the heat storage section 4, the centering jig A24 is attached with bolts 44, the workpiece cradle 10 is removed, the centering jig B26 is attached, and the head 2 is lowered. The centering jig A24 and the centering jig B26 are aligned. At this time, the bolts 44 for fixing the jig base 12 to the machine table 14 are loosened and tightened after the alignment.

その後、前記芯出し治具Ａ２４および前記芯出し治具Ｂ２６を取外し、前記蓄熱部４に前記ヒーターチップ２８を取付け、前記治具用ベース１２に前記加工物の受け台１０を取付け、前記加工物の受け台１０の上に平行検査板２０を載せてから、前記ヘッド２を下降させ、前記ヒーターチップ８の先端部８ｂを押し付け、前記平行検査板２０と前記ヒーターチップ８の先端部８ｂとの間に挟んだ感圧紙の反応結果によって傾きの方向と大きさを判断し、前記受け台１０と前記治具用ベース１２との間に調節シートを挟むことによって前記ヒーターチップの先端８ｂと前記加工物の受け台１０の受け面１０ａの平行度を調節していた。   Thereafter, the centering jig A24 and the centering jig B26 are removed, the heater chip 28 is attached to the heat accumulator 4, the workpiece base 10 is attached to the jig base 12, and the workpiece After the parallel inspection plate 20 is placed on the cradle 10, the head 2 is lowered, the front end portion 8 b of the heater chip 8 is pressed, and the parallel inspection plate 20 and the front end portion 8 b of the heater chip 8 are pressed. The direction and size of the inclination are determined based on the reaction result of the pressure sensitive paper sandwiched between them, and an adjustment sheet is sandwiched between the cradle 10 and the jig base 12, and the tip 8 b of the heater chip and the processing The parallelism of the receiving surface 10a of the object cradle 10 was adjusted.

前述のとおり従来の位置調節方法では、前記芯出し治具により中心合わせを行い、その芯出し治具を外して前記ヒーターチップ８と前記加工物の受け台１０を取付けた後で、平行度を調節していたので、前記ヒーターチップ８と前記加工物の受け台１０を取付けた時に、せっかく合わせた中心が僅かにずれてしまうことが発生し、そのため再び芯出し治具により中心合わせをし直すといった二度手間が頻繁に行われていた。   As described above, in the conventional position adjusting method, the centering is performed by the centering jig, and after the centering jig is removed and the heater chip 8 and the workpiece cradle 10 are attached, the parallelism is adjusted. Since the adjustment has been made, when the heater chip 8 and the workpiece cradle 10 are attached, the center of the alignment may be slightly shifted, so that the centering is performed again by the centering jig. Such a trouble was frequently performed twice.

前述の二度手間が三度四度になることもあり、カシメを行うための準備作業に多大の労力と時間を費やしている。このため作業コストが増加するだけでなく、作業者へ精神的苦痛を与えることにもなっている。   The two-time effort described above may be three or four times, and a great deal of labor and time is spent on preparation work for caulking. This not only increases the work cost, but also causes mental distress to the worker.

本発明は上記課題を解決するためになされたもので、位置調節作業の煩雑さの原因となっている芯出し治具による芯出し調節を行わず、前記ヒーターチップ８と前記加工物の受け台１０を熱カシメ装置に取付けた状態で、前記ヒーターチップ８に対する前記加工物の受け台１０の中心位置合わせと平行度合わせを同時に行うことが出来、これにより作業コストの削減が実現できるとともに、作業者の精神的負担を軽減させることが出来る。   The present invention has been made in order to solve the above-mentioned problems, and does not perform centering adjustment by a centering jig, which is a cause of complicated position adjustment work, and the heater chip 8 and the workpiece cradle. In the state where 10 is attached to the heat caulking device, it is possible to simultaneously align the center position and parallelism of the workpiece cradle 10 with respect to the heater chip 8, thereby realizing a reduction in work cost and work. Can reduce the mental burden of the person.

本発明は前記加工物にカシメ加工を施す熱カシメ装置の調節方法に関して、触針式位置測定器を用いた調節治具と新たな調節方法を提案することにより前記課題を解決することを目的とする。   The present invention relates to an adjustment method of a thermal caulking device that performs caulking processing on the workpiece, and an object thereof is to solve the above-mentioned problem by proposing an adjustment jig using a stylus type position measuring device and a new adjustment method. To do.

上記目的を達成するために、前記ヒーターチップ８の前記加工物と接触する逆擂鉢状となった円錐形状の押圧面を、回転する台座と触針式位置測定器とからなる調節治具を用いて計測し、前記円錐形状の押圧面が前記加工物の加工部分に対して平行且つ同芯となるように、前記加工物の位置決め部材である治具用ベース１２と受け台１０の位置を調節してから、前記加工物を所定形状に塑性変形させることを特徴とする。   In order to achieve the above-mentioned object, an adjustment jig comprising a rotating pedestal and a stylus-type position measuring device is used for the conical pressing surface in the shape of an inverted bowl that contacts the workpiece of the heater chip 8. The position of the jig base 12 and the cradle 10 that are positioning members of the workpiece is adjusted so that the conical pressing surface is parallel and concentric with the processed portion of the workpiece. Then, the workpiece is plastically deformed into a predetermined shape.

前記ヒーターチップ８の円錐形状の押圧面を、前記調節治具３０を用いて計測する場合、前記ヒーターチップ８は前記蓄熱部４から伝播される熱によって加熱された状態で計測が行われることが良い。   When measuring the conical pressing surface of the heater chip 8 using the adjusting jig 30, the heater chip 8 may be measured while being heated by the heat transmitted from the heat storage unit 4. good.

本発明の熱カシメ装置の調節治具を用いた位置調節方法によれば、ヒーターチップと加工物の受け台の位置合わせにおいて、熱カシメ装置からヒーターチップや加工物の受け台を取外す必要がなく、ヒーターチップや加工物の受け台を取付けた状態で、ヒーターチップと加工物の受け台の位置合わせを行うことが出来る。     According to the position adjustment method using the adjustment jig of the thermal caulking device of the present invention, it is not necessary to remove the heater chip and the workpiece cradle from the thermal caulking device when aligning the heater chip and the workpiece cradle. With the heater chip and workpiece cradle attached, the heater chip and workpiece cradle can be aligned.

このように本発明の熱カシメ装置の調節治具を用いた位置調節方法によれば、熱カシメ装置からヒーターチップを取外す必要がなく、加工物の受け台の位置合わせも一度で済み、加工物の受け台の位置調節を何度も繰り返すといった無駄なことをすることがなくなるので、準備作業に多大の労力と時間を費やすことがなくなる。これにより作業コストの削減が実現できるとともに、作業者に精神的苦痛を与えることもなくなる。   Thus, according to the position adjusting method using the adjusting jig of the heat caulking device of the present invention, it is not necessary to remove the heater chip from the heat caulking device, and the positioning of the work cradle can be performed only once. Therefore, it is not necessary to perform a wasteful process of adjusting the position of the cradle many times, so that a great deal of labor and time are not spent on preparation work. As a result, the work cost can be reduced and the worker is not mentally pained.

本発明を適用した熱カシメ装置の調節治具および調節方法について、以下説明を行う。図３は熱カシメ装置に設置した加工物の受け台１０の上に調節治具３０を乗せた状態を現した図で、一部を断面で示す。   The adjustment jig and adjustment method of the thermal caulking device to which the present invention is applied will be described below.

Yes. The mating surface 32a in contact with the receiving surface 10a is a flat surface, and the receiving surface 10b in contact with the centering surface 10b has a cylindrical shape. Thereby, the pedestal 32 of the adjusting jig 30 rotates about the center of the cradle 10.

前記調節治具３０の上部には前記触針式位置測定器３１があり、前記触針式位置測定器３１の先端に設けられている触針３１ａは、前記ヒーターチップ８の押圧面８ａに接触している。前記触針３１ａは、前記台座３２を回転させることにより、前記押圧面８ａに接触しながら回転し、前記押圧面８ａを計測する。   Above the adjustment jig 30 is the stylus position measuring device 31, and the stylus 31 a provided at the tip of the stylus position measuring device 31 contacts the pressing surface 8 a of the heater chip 8. is doing. The stylus 31a rotates while contacting the pressing surface 8a by rotating the pedestal 32, and measures the pressing surface 8a.

次に本発明を適用した熱カシメ装置の調節治具を用いた調節方法の測定手順および作用について、以下説明を行う。図３において、加工物の受け台１０の上に、前記調節治具３０をのせ、回転自在に装着された前記調節治具３０の上部に設けられた前記触針式位置測定器３１の触針３１ａを、前記ヒーターチップ８の押圧面８ａの任意の１点に接触させる。   Next, the measurement procedure and operation of the adjustment method using the adjustment jig of the thermal caulking device to which the present invention is applied will be described below. In FIG. 3, the adjustment jig 30 is placed on the workpiece cradle 10 and the stylus of the stylus type position measuring device 31 provided on the adjustment jig 30 that is rotatably mounted. 31 a is brought into contact with an arbitrary point on the pressing surface 8 a of the heater chip 8.

次に前記台座３２を１８０度回転させ、前記触針３１ａが前記押圧面８ａに接触していることを確認する。この時、前記触針３１ａが前記押圧面８ａからはなれていたり、前記台座３２の回転を妨げるほど重なっている場合は、前記受け台１０の位置を修正し、前記受け台１０の中心が前記ヒーターチップ８のほぼ真下となるようにする。   Next, the pedestal 32 is rotated 180 degrees to confirm that the stylus 31a is in contact with the pressing surface 8a. At this time, if the stylus 31a is separated from the pressing surface 8a or overlaps to prevent the pedestal 32 from rotating, the position of the cradle 10 is corrected, and the center of the cradle 10 is the heater It should be almost directly below the chip 8.

その状態で前記台座３２を１回転させると、前記触針３１ａが前記ヒーターチップ８の押圧面８ａ表面に接触しながら円を描く。このときの前記触針３１ａの前記押圧面８ａとの接触位置が、真円との差として計測され、計測されたデーターが全て０である場合は、真円ということになる。   When the pedestal 32 is rotated once in this state, the stylus 31a draws a circle while contacting the surface of the pressing surface 8a of the heater chip 8. At this time, the contact position of the stylus 31a with the pressing surface 8a is measured as a difference from a perfect circle, and when all measured data is 0, it is a perfect circle.

この計測方法は前記触針３１ａによって円錐形状の押圧面８ａを内側から輪切りにするのと同じことで、前記触針３１ａ軌跡は円錐形状の押圧面８ａの切り口と同じであり、その切り口が真円であれば、前記調節治具３０はその回転中心が円錐形状の前記押圧面８ａの中心と一致していることであり且つ平行であることであり、前記加工物の受け台１０と前記ヒーターチップ８が同芯且つ平行であることになる。   This measurement method is the same as that the cone-shaped pressing surface 8a is cut from the inside by the stylus 31a, and the locus of the stylus 31a is the same as that of the conical pressing surface 8a. If it is a circle, the adjustment jig 30 has a center of rotation that coincides with and is parallel to the center of the conical pressing surface 8a, and the workpiece cradle 10 and the heater The chip 8 is concentric and parallel.

計測されたデーターが０でない場合は、その計測値の最大値の発生した方向で、ずれている方向が判明するし、各測定値の＋あるいは−の値の大きさとその出方によっても、その修正すべき方向が判明する。   If the measured data is not 0, the direction in which the maximum value of the measured value has occurred is found to be shifted, and the magnitude of the + or-value of each measured value and the way it comes out The direction to be corrected is found.

例えば平行度は良いが中心がずれている場合は、最大値の＋と−がほぼ同じか近い値として計測されるが、中心は合っているが平行度が正しくない場合は、最大値の＋と−の値に差が生じる。両方が狂っている場合は、すべての測定値を勘案し、ずれの原因を推測して調節する。   For example, if the parallelism is good but the center is shifted, the maximum value + and-are measured as approximately the same or close values, but if the center is correct but the parallelism is not correct, the maximum value + A difference occurs between the values of-and-. If both are upset, take into account all measurements and adjust for the cause of the shift.

次に図４および図５にて本発明による調節治具を用いた調節方法によって正しく調節された、熱カシメ装置によるレンズ枠のカシメ作業について説明する。   Next, the caulking operation of the lens frame by the thermal caulking device that has been correctly adjusted by the adjusting method using the adjusting jig according to the present invention will be described with reference to FIGS.

前述の調節作業により位置合わせが済んだ前記受け台１０に、レンズ枠１８を載せ、レンズ枠１８にレンズ１６を挿入する（図５（Ａ）参照）。その後、熱カシメ装置の前記ヘッド２を押し下げ、加熱した前記ヒーターチップ８の押圧面８ａをレンズ枠１８のカシメ代部１８ａに押し付ける（図５（Ｂ）参照）。レンズ枠１８のカシメ代部１８ａは、前記ヒーターチップ８の押圧面８によって、レンズ１６の側へ押し倒され、所定の形状に塑性変形される（図５（Ｃ）参照）。その後前記ヘッド２を上方へ戻すことで前記ヒーターチップ８も前記レンズ枠１８から離れ、レンズ１６がレンズ枠１８にカシメられたものを取出すことが出来る。   The lens frame 18 is placed on the cradle 10 that has been aligned by the adjustment operation described above, and the lens 16 is inserted into the lens frame 18 (see FIG. 5A). Thereafter, the head 2 of the heat caulking device is pushed down, and the heated pressing surface 8a of the heater chip 8 is pressed against the caulking margin 18a of the lens frame 18 (see FIG. 5B). The caulking margin 18a of the lens frame 18 is pushed down toward the lens 16 by the pressing surface 8 of the heater chip 8 and plastically deformed into a predetermined shape (see FIG. 5C). Thereafter, by returning the head 2 upward, the heater chip 8 is also separated from the lens frame 18 and the lens 16 is caulked to the lens frame 18 can be taken out.

なお、上記実施形態では、前記調節治具３０の台座３２は前記受け台１０の合わせ面３２ｂにガイドされて回転する構造となっているが、本発明はこれに限定されるものではなく、図６に示すように治具用ベース１２の位置決め用ボス１２ａを長くして、前記台座３２の中心に明けた穴を嵌め込んで、前記台座３２を回転させるようにしても良い。   In the above embodiment, the pedestal 32 of the adjustment jig 30 is structured to rotate while being guided by the mating surface 32b of the cradle 10. However, the present invention is not limited to this. 6, the positioning boss 12 a of the jig base 12 may be lengthened, and a hole formed in the center of the pedestal 32 may be fitted to rotate the pedestal 32.
