Description
本発明は、筒状部材の両端に形成された開口周縁部にグリース塗布作業とボール装着作業を行う組付装置に関する。
The present invention relates to an assembling apparatus that performs a grease application operation and a ball mounting operation on the peripheral edge of an opening formed at both ends of a cylindrical member.
従来、自動二輪車のヘッドパイプの両端に形成された開口周縁部（ベアリング用ボールレース部）にグリースを塗布する作業と、グリースが塗布された開口周縁部に所定数のベアリングボールを配列する作業が手作業により行われていることが知られている。
Conventionally, there has been an operation of applying grease to the opening peripheral portion (bearing ball race portion) formed at both ends of the head pipe of the motorcycle and an operation of arranging a predetermined number of bearing balls on the opening peripheral portion to which the grease has been applied. It is known that it is done manually.
また、ワークに対して常に均一にグリースを塗布するために、グリース供給ノズルに対して傾動可能に配設されたノズルヘッドのテーパ面をヘッドパイプの開口端面に直接当接させることによってボールレース部との位置決めを行い、このボールレース部に複数のグリース吐出通路から一時にグリースを吐出させる技術が知られている（例えば、特許文献１参照）。
In addition, in order to always apply grease uniformly to the workpiece, the ball race portion is formed by directly contacting the taper surface of the nozzle head arranged to be tiltable with respect to the grease supply nozzle to the opening end surface of the head pipe. A technique is known in which grease is discharged at once from a plurality of grease discharge passages to the ball race portion (see, for example, Patent Document 1).
しかし、手作業によるボールレース部へのグリース塗布は、作業者の勘などに頼る手作業であるため塗布が片寄って均一にならない場合がある。また、塗布量も不均一でばらつきが発生する場合がある。更に、ヘッドパイプを支持する治具に付着したグリースを拭き取る作業が発生してしまうという問題がある。
また、特許文献１に記載の技術のように、グリース塗布作業を自動化しても、ボールのヘッドパイプへの配列は、作業者の勘などに頼る手作業であるためボールの落下や数不足が発生してしまうという問題がある。 However, since the grease application to the ball race portion by manual work is a manual work that relies on the operator's intuition, the application may be uneven and may not be uniform. Also, the coating amount may be non-uniform and may vary. Furthermore, there is a problem that an operation of wiping off the grease adhering to the jig that supports the head pipe occurs.
Moreover, even if the grease application operation is automated as in the technique described inPatent Document 1, since the arrangement of the balls on the head pipe is a manual operation that relies on the operator's intuition and the like, there is no drop or shortage of balls. There is a problem that it occurs.

In the case where the cold air is low-temperature nitrogen gas, the cold air supply device 33 includes a liquid nitrogen cylinder and a liquid nitrogen vaporizer that vaporizes the liquid nitrogen. Further, in the case where the cold air is a low-temperature air, the cold air supply device 33 is configured by an ultra-low temperature air generator that generates ultra-low temperature air.
以上のように構成された本発明に係る組付装置の動作について説明する。先ず、下側のボールレース部２を下ヘッド部６の溝部１２に嵌合させ、更にシリンダ１４を駆動状態にさせて上ヘッド部５を下降させ上側のボールレース部２に嵌合させる。これにより、ヘッドパイプ１は上ヘッド部５と下ヘッド部６によって安定した状態で挟持される。すると、自動二輪車のフレームを構成するヘッドパイプ１が本装置にセットされる。
The operation of the assembling apparatus according to the present invention configured as described above will be described. First, the lower ball race portion 2 is fitted into the groove portion 12 of the lower head portion 6, and the cylinder 14 is further driven to lower the upper head portion 5 to be fitted to the upper ball race portion 2. Thereby, the head pipe 1 is clamped in a stable state by the upper head portion 5 and the lower head portion 6. Then, the head pipe 1 constituting the motorcycle frame is set in this apparatus.
次いで、ボール供給手段７により所定数（例えば、２１個）のボール４を上ヘッド部５と下ヘッド部６に供給する。すると、図６に示すように、上ヘッド部５のボール保持部１６と下ヘッド部６のボール保持部１６に夫々供給された２１個のボール４は、環状に配列保持される。ボール４が上ヘッド部５のボール保持部１６に供給されても、環状の弾性ストッパ１７により落下することはない。
Next, a predetermined number (for example, 21) of balls 4 are supplied to the upper head portion 5 and the lower head portion 6 by the ball supply means 7. Then, as shown in FIG. 6, the 21 balls 4 respectively supplied to the ball holding portion 16 of the upper head portion 5 and the ball holding portion 16 of the lower head portion 6 are arranged and held in an annular shape. Even if the ball 4 is supplied to the ball holding portion 16 of the upper head portion 5, it does not fall by the annular elastic stopper 17.
次いで、グリース圧送手段８により、グリース３を圧送して上ヘッド部５と下ヘッド部６の内蔵部１１，１１に設けた複数の吐出口１８からボールレース部２，２近傍で外筒部１０と内蔵部１１の間に定量のグリース３を吐出する。グリース３は適度の粘性を有するので、垂れたりすることなく吐出した状態を維持することができる。なお、ボール４をボール保持部１６に配列するのと、グリース３をボールレース部２，２近傍に吐出するのは、いずれを先にしてもよい。
Next, grease 3 is pumped by the grease pumping means 8, and the outer cylinder portion 10 near the ball race portions 2, 2 from a plurality of discharge ports 18 provided in the built-in portions 11, 11 of the upper head portion 5 and the lower head portion 6. A fixed amount of grease 3 is discharged between the internal portion 11 and the internal portion 11. Since the grease 3 has an appropriate viscosity, the discharged state can be maintained without dripping. Note that either the arrangement of the balls 4 in the ball holding section 16 or the discharge of the grease 3 to the vicinity of the ball race sections 2 and 2 may be performed first.
次いで、ボール圧送手段９のピストン２０を前進させることにより、ボール保持部１６，１６に配列保持された所定数のボール４を一括圧送する。すると、図７に示すように、所定数のボール４が弾性ストッパ１７，１７を乗り越えて、ボールレース部２，２近傍に吐出されていたグリース３を押し出すと同時に、グリース３と共にボールレース部２，２に装着する。
Next, by moving the piston 20 of the ball pumping means 9 forward, a predetermined number of balls 4 arranged and held in the ball holding portions 16 and 16 are collectively pumped. Then, as shown in FIG. 7, a predetermined number of balls 4 get over the elastic stoppers 17, 17 to push out the grease 3 discharged in the vicinity of the ball race portions 2, 2, and at the same time, together with the grease 3, the ball race portion 2. , 2 is attached.
更に、グリース硬化手段３０によりボールレース部２，２に装着したグリース３に冷風を噴射することもできる。冷風の噴射によりグリース３が一時的に硬化するので、グリース３と共にヘッドパイプ１両端のボールレース部２，２に装着したボール４が脱落するのを防止することができる。特に、下ヘッド部６から圧送されてボールレース部２に装着したボール４の脱落防止には有効である。
Furthermore, cold air can be sprayed onto the grease 3 attached to the ball race portions 2 and 2 by the grease curing means 30. Since the grease 3 is temporarily cured by the injection of the cold air, it is possible to prevent the balls 4 attached to the ball race portions 2 and 2 at both ends of the head pipe 1 from dropping together with the grease 3. In particular, it is effective for preventing the balls 4 fed from the lower head part 6 and mounted on the ball race part 2 from falling off.
次いで、シリンダ１４の駆動状態を解除する。すると、スプリング１５により上ヘッド部５が上昇し、上ヘッド部５が上側のボールレース部２から離れる。更に、ヘッドパイプ１を持ち上げて下側のボールレース部２を下ヘッド部６から離す。下側のボールレース部２に装着されたボール４は、ボールレース部２とボール４の間に配設されたグリース３の吸着力により落下することはない。
Next, the drive state of the cylinder 14 is released. Then, the upper head portion 5 is raised by the spring 15, and the upper head portion 5 is separated from the upper ball race portion 2. Further, the head pipe 1 is lifted to separate the lower ball race portion 2 from the lower head portion 6. The ball 4 mounted on the lower ball race portion 2 does not fall due to the adsorption force of the grease 3 disposed between the ball race portion 2 and the ball 4.
このようにして、ヘッドパイプ１両端のボールレース部２，２に定量のグリース３を塗布すると共に、所定数（例えば、２１個）のボール４を装着させる作業が一つの工程で行われる。
In this way, a fixed amount of grease 3 is applied to the ball race portions 2 and 2 at both ends of the head pipe 1 and a predetermined number (for example, 21) of balls 4 is mounted in one process.
本発明によれば、自動二輪車のフレームを構成するヘッドパイプなどの筒状部材の両端に形成された開口周縁部に定量のグリース塗布及び所定数のボール装着を一つの工程で確実に行うことができ、グリース塗布作業及びボール装着作業のサイクルタイムの短縮が図れ
、的確に定量だけグリースを塗布することができるので、グリース使用量の削減が図れる。 According to the present invention, it is possible to reliably apply a predetermined amount of grease and mount a predetermined number of balls on the peripheral edge of an opening formed at both ends of a cylindrical member such as a head pipe constituting a frame of a motorcycle in one process. In addition, the cycle time of the grease application operation and the ball mounting operation can be shortened, and the grease can be applied accurately in a predetermined amount, so that the amount of grease used can be reduced.
