【考案の詳細な説明】
本考案は円筒部に形成された加工穴の面取りを行なう面
取り工具に関するものであって、その目的とするところ
は工具が穴加工部の形状に沿いごますり運動を行うよう
になると共に強い切削力に耐えるる面取り工具を提供す
ることにある。[Detailed description of the invention] The present invention relates to a chamfering tool for chamfering a machined hole formed in a cylindrical part. It is an object of the present invention to provide a chamfering tool that can be used for cutting and withstand strong cutting forces.
以下、本考案を図面を参照して説明する。Hereinafter, the present invention will be explained with reference to the drawings.
図面中１は主軸であり、この主軸１の端面には凹形の球
面受座２が嵌着しである。In the drawing, 1 is a main shaft, and a concave spherical seat 2 is fitted onto the end surface of the main shaft 1.
主軸１にはハウジング３が嵌着してあり、このハウジン
グ３には軸線方向に長い長孔部４が形成しである。A housing 3 is fitted onto the main shaft 1, and the housing 3 has an elongated hole 4 formed in the axial direction.
ハウジング３内にはホルダ５の後部が挿入してあり、こ
のホルダ５の後端部にはピン６が取付けてあり、このピ
ン６が前記長孔部４に移動可能に挿入しである。A rear part of a holder 5 is inserted into the housing 3, and a pin 6 is attached to the rear end of the holder 5, and the pin 6 is movably inserted into the elongated hole 4.
ホルダ５の端部には凸形の球面部７が形成してあり、こ
の球面部７が前記球面受座２に衝合している。A convex spherical part 7 is formed at the end of the holder 5, and this spherical part 7 abuts against the spherical seat 2.
またホルダ５のばね座８とハウジング３のばね座９との
間にばね１０が介装しである。Further, a spring 10 is interposed between the spring seat 8 of the holder 5 and the spring seat 9 of the housing 3.
ホルダ９には工具１１が着脱可能に取付けである。A tool 11 is removably attached to the holder 9.
前記ホルダ５はピン６が長孔部４内を動ける範囲内でピ
ン６の中央点を中心に揺動が自在になされており、ばね
１０はホルダ５の球面部を球面座に押圧し工具１１のふ
らつきをなくしている。The holder 5 is able to swing freely about the center point of the pin 6 within the range in which the pin 6 can move within the elongated hole 4, and the spring 10 presses the spherical part of the holder 5 against the spherical seat, and the tool 11 This eliminates the wobbling.
しかして、工具１１の先端は第３図に示すようにＸ、
Ｙ方向に可動となり、非円形穴の均一な面取りが可能に
なる。Therefore, the tip of the tool 11 has an X, as shown in FIG.
It is movable in the Y direction, making it possible to uniformly chamfer non-circular holes.
面取り加工中軸方向の推力は球面当接部で受けることに
なるので工具１１の先端がＸ、 Ｙ方向に扁位しても無
理なく主軸１の推力が工具１１に伝達される。During chamfering, the thrust in the axial direction is received by the spherical contact portion, so even if the tip of the tool 11 is tilted in the X and Y directions, the thrust of the spindle 1 is easily transmitted to the tool 11.
なお、主軸１の回転はハウジング３、ピン６を介してホ
ルダ５に伝達される。Note that the rotation of the main shaft 1 is transmitted to the holder 5 via the housing 3 and the pin 6.
本考案は上記のように、主軸１に取付けられて周部に軸
方向に長い長孔部４を形成したハウジング３と、主軸１
の端部に設けられた球面受座２と、ハウジング３内に後
部が隙間を存して挿入されて工具１１を保持するホルダ
５と、ホルダ５に取付けられて端部が長孔部４に挿入さ
れたピン６と、ホルダ５の後端部に設けられて前記球面
受座２に当接する球面部７と、ハウジング３内に設けら
れてホルダ５を後方に付勢して球面部７を球面受座２に
当接させるばね１０とを備えたことを特徴とする面取り
工具である。As described above, the present invention includes a housing 3 that is attached to the main shaft 1 and has an axially long elongated hole 4 formed in the circumference, and
a spherical catch 2 provided at the end of the housing 3; a holder 5 whose rear end is inserted into the housing 3 with a gap to hold the tool 11; The inserted pin 6, the spherical part 7 provided at the rear end of the holder 5 and in contact with the spherical seat 2, and the spherical part 7 provided in the housing 3 to urge the holder 5 backward. This chamfering tool is characterized by comprising a spring 10 that is brought into contact with a spherical seat 2.
したがって、面取り加工中軸方向の推力は球面受座２と
球面部７とがなす球面当接部で受けることになるので工
具１１の先端がＸ、 Ｙ方向に偏位しても無理なく主軸
１の推力が工具１１に伝達される。Therefore, the thrust in the axial direction during chamfering is received by the spherical abutment formed by the spherical catch 2 and the spherical part 7, so even if the tip of the tool 11 deviates in the X and Y directions, it will not be difficult for the main shaft 1 to Thrust is transmitted to the tool 11.
このために強い切削力に耐えることができる。This allows it to withstand strong cutting forces.
また無負荷時には主軸１の中心と工具１１の中心が一致
しているが切削（面取り）時には工具１１が穴加工部形
状に安易に沿いごますり運動を行うようになる。Furthermore, when there is no load, the center of the spindle 1 and the center of the tool 11 coincide, but during cutting (chamfering), the tool 11 easily moves along the shape of the hole being machined.
したがって、従来の面取り工具に比較して構造が簡単に
なり安価に製作できる。Therefore, compared to conventional chamfering tools, the structure is simpler and can be manufactured at a lower cost.
しかも面取り動作も確実なものになる。Moreover, the chamfering operation becomes reliable.
