従来、一般に用いられているチャッキング装置は図２に示すように同期回転さ れる主軸１とこれに対向する副主軸２のそれぞれにパイプ３の穴に嵌合する案内 部４とパイプ端面を挟持する段部５を有する支持治具６を同心に取付け、パイプ ３の両端より挿通支持し端面を押圧してチャッキングし両主軸１，２を同期回転 してバイトによりパイプ外径を加工していた。 2. Description of the Related Art Conventionally, a generally used chucking device sandwiches a guide portion 4 and a pipe end surface which are fitted in a hole of a pipe 3 on a main shaft 1 which is synchronously rotated and a sub main shaft 2 which faces the main shaft 1 as shown in FIG. A support jig 6 having a step portion 5 is attached concentrically, inserted and supported from both ends of the pipe 3, the end faces are pressed and chucked, both spindles 1 and 2 are synchronously rotated, and the pipe outer diameter is processed by a cutting tool.

通常加工されるべきパイプの端面は旋盤によって荒仕上げ加工が行われている 程度であって、パイプ軸芯と正確に直角な端面には仕上がっていない場合がしば しばある。このため端面直角度不良のものが両端から支持治具と一体の段部で挟 持されるとパイプ端面は段部に倣い強制的に曲げられ振れが生じる。したがって 変形状態で外径加工を行うと支持治具より取外したときに復元して外径加工精度 が劣化するという問題がある。 本考案は従来の技術の有するこのような問題点に鑑みなされたもので、その目 的とするところは薄肉円筒体の端面加工の状態如何にかかわらず加工精度を劣化 させないチャッキング装置を提供しようとするものである。 Normally, the end surface of the pipe to be machined is only rough-finished by a lathe, and the end surface that is exactly perpendicular to the pipe axis is often not finished. For this reason, if the end face perpendicularity defect is sandwiched from both ends by a step portion integrated with the support jig, the pipe end surface is forcibly bent following the step portion to cause runout. Therefore, if the outer diameter is machined in the deformed state, there is a problem that the outer diameter machining accuracy is deteriorated by being restored when it is removed from the supporting jig. The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a chucking device that does not deteriorate the processing accuracy regardless of the end surface processing state of the thin-walled cylindrical body. It is what

上述の目的を達成するために本考案は、薄肉円筒体の両端を支持する装置であ って、第１主軸と該第１主軸に対向する第２主軸のそれぞれに同心に設けられ前 記薄肉円筒体の穴に嵌合する支持筒と、該それぞれの支持筒に硬質ゴム等の柔軟 性を有する材料であるカラーで位置決めされるとともにフローティング可能に装 着された端面押圧筒とを含んでなるものである。 In order to achieve the above-mentioned object, the present invention is a device for supporting both ends of a thin-walled cylindrical body, which is provided concentrically with each of a first spindle and a second spindle facing the first spindle. It includes a support cylinder fitted into the hole of the cylindrical body, and an end face pressing cylinder which is positioned in a collar, which is a material having flexibility such as hard rubber, in each of the support cylinders and which is mounted in a floating manner. It is a thing.

薄肉円筒体の両端面より支持筒を挿通し第２主軸側を前進させて端面押圧筒に より押圧面に滑りのない圧力で挟持する。端面押圧筒は柔軟性材料でなるカラー で支持されたフローティング構造であるので挟持面が薄肉円筒体の端面にならっ て端面押圧筒は変位する。 The support cylinder is inserted from both end faces of the thin-walled cylindrical body, and the second spindle side is advanced to be clamped by the end face pressing cylinder with a pressure without slippage on the pressing surface. Since the end face pressing cylinder has a floating structure supported by a collar made of a flexible material, the end face pressing cylinder is displaced so that the holding surface becomes the end face of the thin-walled cylindrical body.

以下本考案の実施例を図１にもとづき説明する。 周知の旋盤の主軸１１の端面に固定された面板１２には支持筒１３を中心に着 脱可能に設けたチャック本体１４が主軸と同心に取付けられている。支持筒１３ は薄肉円筒体１０の穴１０ａに挿入容易とするため先端をテーパとし円筒穴に隙 間なく嵌合する支持部１３ａにつづく小径の首部に薄肉円筒体１０の端面に当接 する端面１５ａを有する端面押圧筒１５がチャック本体１４の中心突出端１４ａ に位置決めする柔軟性ある材料例えば所定圧以上で変形可能な硬質ゴムでなるカ ラー１６を軸方向中央部に介して同心に嵌装されている。そしてカラー１６の前 側で首部との間にＯリング１７を、またカラー１６の後側で中心突出端１４ａと の間にＯリング１８が介装されていて端面押圧筒１５はラジアル，スラスト方向 にフローティング可能でカラー１６を中心としてチルチングできる。 An embodiment of the present invention will be described below with reference to FIG. On a face plate 12 fixed to an end surface of a main shaft 11 of a known lathe, a chuck body 14 which is detachably provided around a support cylinder 13 is attached concentrically with the main shaft. The support cylinder 13 has a tapered tip for facilitating insertion into the hole 10a of the thin-walled cylindrical body 10, and a support portion 13a that fits tightly into the cylindrical hole. The end face pressing cylinder 15 having 15a is positioned on the central protruding end 14a of the chuck body 14 and is concentrically fitted with a colorant 16 made of a flexible material, for example, hard rubber which is deformable under a predetermined pressure or more, in the axial center portion. Has been done. An O-ring 17 is provided on the front side of the collar 16 with the neck portion, and an O-ring 18 is provided on the rear side of the collar 16 with the central projecting end 14a, so that the end face pressing cylinder 15 is in the radial and thrust directions. It can be floated and can be tilted around the collar 16.
【０００７】 主軸１１と対向し同心で軸方向に位置調整可能な副主軸２１の中心取付体２２ にも前述と同じ支持筒，端面押圧筒が同様に取付けられており、同符号を付して 説明を省略する。 このように構成された本考案の作用を説明する。 ＮＣ又は手動で副主軸２１が後退され、ロボット，ローダ若しくは手で薄肉円 筒体１０が主軸軸線上に搬入され、主軸１１側の支持筒１３に一端の穴を嵌装さ せる。副主軸２１を前進させて支持筒１３を他端の穴に臨ませ、更に前進させて 端面押圧筒１５の端面１５ａで薄肉円筒体１０を挟持する。このとき副主軸２１ の前進量を規定して薄肉円筒体１０が切削時に挟持端面に滑りが起こらない程度 の力で挟持させる。このとき薄肉円筒体１０の端面の軸芯に対する直角度が良く ないと端面押圧筒１５がチルチングして端面１５ａが倣い平均された押圧力で挟 持する。The same support cylinder and end face pressing cylinder as those described above are also attached to the center mounting body 22 of the sub-spindle 21 which is concentric with the main shaft 11 and whose position can be adjusted in the axial direction. The description is omitted. The operation of the present invention thus constructed will be described. The sub-spindle 21 is retracted by NC or manually, and the thin-walled cylindrical body 10 is loaded onto the spindle axis by a robot, a loader or by hand, and a hole at one end is fitted into the support cylinder 13 on the spindle 11 side. The sub spindle 21 is moved forward so that the support cylinder 13 faces the hole at the other end, and is further moved forward to clamp the thin cylindrical body 10 by the end surface 15a of the end surface pressing cylinder 15. At this time, the advancing amount of the sub spindle 21 is regulated so that the thin-walled cylindrical body 10 is clamped with a force such that the clamping end face does not slip during cutting. At this time, if the perpendicularity of the end surface of the thin-walled cylindrical body 10 to the axis is not good, the end surface pressing cylinder 15 tilts and the end surface 15a is copied and held by the averaged pressing force.

上述のようであるので本考案は以下の効果を奏する。 薄肉工作物端面の軸芯に対する直角度が出るような精度高い前加工を行う必要 がなくなり加工コストが低減できるとともに曲がりの発生が防止され振れのない 安定した加工精度を得ることができる。 As described above, the present invention has the following effects. Since it is not necessary to perform high-precision pre-machining such that the perpendicularity of the end face of the thin-walled work piece to the axis is obtained, the machining cost can be reduced, and the occurrence of bending is prevented and stable machining accuracy without runout can be obtained.
