Description

本発明は、インサートを着脱可能な分割ホブを組み立てて多巻ホブとして構成したスローアウェイ式ホブに関する。   The present invention relates to a throw-away hob constructed by assembling a split hob to which an insert can be attached and detached as a multi-turn hob.

従来から、インボリュート歯車を創成法を用いて歯切りする工具として、インサート（歯切り用チップ）を着脱可能とした、スローアウェイ式のホブが周知となっている。更に、このスローアウェイ式ホブの中には、複数の１巻ホブを組み立てて多巻ホブとして構成したものが提供されている。そして、このような、分割構造を採用したスローアウェイ式ホブは、例えば、特許文献１に開示されている。   2. Description of the Related Art Conventionally, a throw-away type hob in which an insert (tooth cutting tip) is detachable is known as a tool for cutting an involute gear using a generating method. Further, among the throwaway hobbs, there are provided a plurality of one-turn hobbs assembled as a multi-turn hob. Such a throw-away hob that employs a divided structure is disclosed in Patent Document 1, for example.

特開２０００−２３３３２１号公報JP 2000-233321 A

しかしながら、上記従来のスローアウェイ式ホブでは、インサートをホブ回転軸の平行線上に並列しているため、当該インサートの着脱作業時に、ボルトや、このボルトを締め付け及び緩めるためのレンチを、隣接した１巻ホブに干渉させるおそれがある。この結果、インサートの着脱作業性の低下を招いていた。   However, in the above-mentioned conventional throw-away hob, since the insert is arranged in parallel on the parallel line of the hob rotation shaft, a bolt and a wrench for tightening and loosening the bolt are adjacent to each other when the insert is attached or detached. There is a risk of interference with the winding hob. As a result, the insert detachment workability has been lowered.

更に、従来のスローアウェイ式ホブでは、１巻ホブのウォーム巻数が１巻に規定されているので、インサートのホブ回転方向の装着間隔によっては、ウォームの巻軸方向の端面が、インサートを取り付けるための取付座面や、この取付座面付近を、分断するように配置されてしまう。このように、ウォームの巻軸方向の端面が配置されると、インサートの取付剛性を低下させるおそれがある。そこで、このような問題を解消するため、インサートの装着間隔を変更することも可能ではあるが、インサートの配置を所望のものにできなくなってしまう。   Further, in the conventional throw-away hob, the number of worm turns per roll hob is defined as 1 roll, so that the end face of the worm winding axis direction attaches the insert depending on the mounting interval in the hob rotation direction of the insert. The mounting seat surface and the vicinity of the mounting seat surface are arranged so as to be divided. As described above, when the end surface of the worm in the winding axis direction is arranged, there is a possibility that the mounting rigidity of the insert is lowered. Thus, in order to solve such a problem, it is possible to change the mounting interval of the inserts, but the inserts cannot be arranged as desired.

従って、本発明は上記課題を解決するものであって、インサートの着脱作業性及び取付剛性を向上させると共に、インサートの配置の自由度を大きくすることができるスローアウェイ式ホブを提供することを目的とする。   Accordingly, the present invention solves the above-described problems, and an object thereof is to provide a throw-away hob that can improve the detachability and mounting rigidity of the insert and can increase the degree of freedom in the arrangement of the insert. And

上記課題を解決する本発明に係るスローアウェイ式ホブは、
軸部の外周部に螺旋状に形成されるウォームにインサートをホブ回転方向に等角度間隔で着脱可能に装着する円盤状の分割ホブを重ね合わせ、隣接した前記分割ホブ間における前記ウォームの巻軸方向の端面同士を突き合わせることにより、前記分割ホブを多巻ホブとして組み立てるようにしたスローアウェイ式ホブであって、
前記インサートのホブ回転方向の装着間隔を、３６０°を等分できない角度に設定し、
前記端面が、ホブ回転方向に隣接した前記インサート間の中間位置よりも、ホブ回転方向上流側に配置されるように、前記ウォームの巻数を１巻未満に設定する
ことを特徴とする。 The throw-away hob according to the present invention for solving the above problems is
A disc-shaped divided hob on which an insert is detachably mounted at equiangular intervals in the hob rotation direction is superposed on a worm formed in a spiral shape on the outer peripheral portion of the shaft portion, and the winding shaft of the worm between the adjacent divided hobbs. It is a throw-away hob in which the divided hobs are assembled as a multi-turn hob by abutting end surfaces in a direction,
The mounting interval in the hob rotation direction of the insert is set to an angle at which 360 ° cannot be equally divided,
The number of turns of the worm is set to be less than one so that the end face is disposed upstream of the intermediate position between the inserts adjacent to each other in the hob rotation direction.

従って、本発明に係るスローアウェイ式ホブによれば、インサートのホブ回転方向の装着間隔を、３６０°を等分できない角度に設定すると共に、ウォームの巻数を１巻未満に設定することにより、インサートを装着するためのボルト及びレンチの分割ホブへの干渉を抑えることができるので、インサートの着脱作業性を向上させることができる。また、ウォームの巻数を設定する際に、ウォームの端面を、ホブ回転方向に隣接したインサート間の中間位置よりも、ホブ回転方向上流側に配置することにより、インサートの取付剛性を向上させることができる。更に、インサートのホブ回転方向の装着間隔を設定してから、ウォームの巻数及びその端面の配置を設定することにより、インサートの配置の自由度を大きくすることができる。   Therefore, according to the throw-away hob according to the present invention, the insert interval in the hob rotation direction of the insert is set to an angle at which 360 ° cannot be equally divided, and the worm winding number is set to less than 1 Since the interference with the divided hob of the bolt and the wrench for mounting the insert can be suppressed, the detachability of the insert can be improved. Also, when setting the number of turns of the worm, the mounting rigidity of the insert can be improved by arranging the end face of the worm on the upstream side in the hob rotation direction with respect to the intermediate position between the inserts adjacent in the hob rotation direction. it can. Furthermore, by setting the mounting interval in the hob rotation direction of the insert and then setting the number of turns of the worm and the arrangement of the end surfaces thereof, the degree of freedom of arrangement of the insert can be increased.

以下、本発明に係るスローアウェイ式ホブについて、図面を用いて詳細に説明する。   Hereinafter, the throw-away hob according to the present invention will be described in detail with reference to the drawings.

図１及び図２に示したスローアウェイ式のホブ１は、円盤状の端部分割ホブ１１及び中間部分割ホブ１２を重ね合わせて組み立てることにより多巻ホブとした、分割構造を採用している。即ち、ホブ１は、そのホブ回転軸方向両側に配置した端部分割ホブ１１間に、複数の中間部分割ホブ１２を挟持した構造となっている。   The throwaway hob 1 shown in FIG. 1 and FIG. 2 employs a split structure in which a disc-shaped end part hob 11 and an intermediate part part hob 12 are overlaid and assembled to form a multi-turn hob. . That is, the hob 1 has a structure in which a plurality of intermediate portion divided hobs 12 are sandwiched between end portion divided hobs 11 arranged on both sides of the hob rotation axis direction.

図３（ａ），（ｂ）及び図４（ａ），（ｂ）に示すように、端部分割ホブ１１及び中間部分割ホブ１２の軸部２１には、取付用孔２２及び組立用孔２３が開口されている。取付用孔２２は、ホブ１をホブ盤に装着する際に、その主軸が嵌入されるものであって、ホブ回転軸と同軸上に形成されている。一方、組立用孔２３は、端部分割ホブ１１及び中間部分割ホブ１２を組み立てる際に使用するボルトが嵌入されるものであって、取付用孔２２の径方向外側で、且つ、その周方向に等角度間隔で形成されている。   As shown in FIGS. 3A and 3B and FIGS. 4A and 4B, the shaft portion 21 of the end portion divided hob 11 and the intermediate portion divided hob 12 has a mounting hole 22 and an assembly hole. 23 is opened. The mounting hole 22 is a shaft into which the main shaft is fitted when the hob 1 is mounted on the hobbing machine, and is formed coaxially with the hob rotation shaft. On the other hand, the assembling hole 23 is for inserting a bolt used when assembling the end divided hob 11 and the intermediate divided hob 12, and is located radially outside the mounting hole 22 and in the circumferential direction thereof. Are formed at equiangular intervals.

また、軸部２１の外周部には、略台形の縦断面を有するウォーム２４が螺旋状に形成されている。このウォーム２４の巻軸方向両側には、凹状の取付座面２５が、所定の間隔で左右交互に形成されており、この取付座面２５には、ボルト孔２６が形成されている。更に、ウォーム２４には、溝状のチップポケット２７が、取付座面２５のホブ回転方向下流側で、且つ、取付座面２５と面するように形成されている。   A worm 24 having a substantially trapezoidal longitudinal section is formed in a spiral shape on the outer peripheral portion of the shaft portion 21. On both sides of the worm 24 in the winding axis direction, concave mounting seat surfaces 25 are formed alternately at left and right at predetermined intervals, and bolt holes 26 are formed in the mounting seat surfaces 25. Further, a groove-shaped chip pocket 27 is formed in the worm 24 so as to face the mounting seat surface 25 on the downstream side of the mounting seat surface 25 in the hob rotation direction.

即ち、取付座面２５には、インサート（歯切り用チップ）３１がボルト３２によって着脱可能に装着されている。そして、インサート３１を取付座面２５に装着することにより、当該インサート３１の切れ刃が、チップポケット２７を臨むようになっている。   That is, an insert (tooth cutting tip) 31 is detachably mounted on the mounting seat surface 25 by the bolt 32. Then, by attaching the insert 31 to the mounting seat surface 25, the cutting edge of the insert 31 faces the chip pocket 27.

なお、取付座面２５に装着されたインサート３１は、ホブ回転方向に等角度間隔に配置されることになるが、その装着間隔は、３６０°を等分できない角度に設定されている。   The inserts 31 mounted on the mounting seat surface 25 are arranged at equal angular intervals in the hob rotation direction, but the mounting intervals are set at an angle that cannot be equally divided into 360 degrees.

従って、ホブ１がホブ回転軸周りに回転して歯切りを行うときには、インサート３１の切れ刃によって発生した切屑（チップ）は、そのインサート３１のホブ回転方向（巻軸方向）直下に形成されたチップポケット２７に排出される。   Therefore, when the hob 1 rotates around the hob rotation axis to perform gear cutting, chips (chips) generated by the cutting blade of the insert 31 are formed immediately below the hob rotation direction (winding axis direction) of the insert 31. It is discharged into the chip pocket 27.

ここで、ウォーム２４は、その巻数（巻状態）が、１周に満たない１巻（３６０°）未満となっている。また、ウォーム２４の巻軸方向の端面２４ａは、ホブ回転方向に隣接した取付座面２５間の中間位置（中間角度）よりも、ホブ回転方向上流側に設定されている。即ち、ウォーム２４は、その端面２４ａがインサート３１間の中間位置よりもホブ回転方向上流側に配置されるような、１巻未満の巻数（巻状態）となっている。なお、図１乃至図５においては、１つの例として、ウォーム２４の巻数を０．９７巻としている。   Here, the number of turns (winding state) of the worm 24 is less than one turn (360 °) which is less than one turn. Further, the end surface 24a in the winding axis direction of the worm 24 is set upstream of the intermediate position (intermediate angle) between the mounting seat surfaces 25 adjacent in the hob rotation direction. That is, the worm 24 has a number of turns (winding state) of less than one so that the end surface 24a is disposed upstream of the intermediate position between the inserts 31 in the hob rotation direction. 1 to 5, as an example, the number of turns of the worm 24 is 0.97.

よって、ホブ１を組み立てる場合には、先ず、被加工歯車の諸元や加工条件（被加工歯車の回転速度、ホブ１の回転速度、切り込み量等）に基づいて、取付座面２５の巻軸方向の設置間隔、即ち、インサート３１のホブ回転方向の装着間隔を設定する。   Therefore, when assembling the hob 1, first, the winding shaft of the mounting seat surface 25 is determined based on the specifications of the gear to be processed and the processing conditions (the rotational speed of the gear to be processed, the rotational speed of the hob 1, the depth of cut, etc.). The installation interval in the direction, that is, the mounting interval in the hob rotation direction of the insert 31 is set.

次いで、ウォーム２４の端面２４ａが取付座面２５間の中間位置よりもホブ回転方向上流側に配置されるように、ウォーム２４の巻数を１巻未満に設定した後、このようなウォームを備える端部分割ホブ１１及び中間部分割ホブ１２を製造する。   Next, after setting the number of turns of the worm 24 to be less than 1 so that the end face 24a of the worm 24 is disposed upstream of the intermediate position between the mounting seat faces 25 in the hob rotation direction, the end provided with such a worm is provided. The partially divided hob 11 and the intermediate divided hob 12 are manufactured.

そして、端部分割ホブ１１及び中間部分割ホブ１２の軸部２１をホブ回転軸方向に重ね合わせると共に、それらの端面２４ａ同士を、ウォーム２４が巻軸方向に連続するように突き合わせる。   Then, the shaft portions 21 of the end divided hob 11 and the intermediate divided hob 12 are overlapped in the hob rotation axis direction, and their end surfaces 24a are butted together so that the worm 24 is continuous in the winding axis direction.

次いで、軸部２１の重ね合わせにより連通した組立用孔２３に、ボルトを貫通させる。これにより、端部分割ホブ１１と中間部分割ホブ１２との間の連結が完了する。   Next, the bolt is passed through the assembly hole 23 communicated by overlapping the shaft portions 21. Thereby, the connection between the end part divided hob 11 and the intermediate part divided hob 12 is completed.

そして、インサート３１をボルト３２により取付座面２５に固定する。これにより、ホブ１の最終的な組み立てが完了する。   Then, the insert 31 is fixed to the mounting seat surface 25 with bolts 32. Thereby, the final assembly of the hob 1 is completed.

従って、本発明に係るスローアウェイ式のホブ１によれば、インサート３１のホブ回転方向の装着間隔を、３６０°を等分できない角度に設定すると共に、ウォーム２４の巻数を１巻未満に設定することにより、図５に示すように、隣接した端部分割ホブ１１と中間部分割ホブ１２との間、及び、隣接した中間部分割ホブ１２間において、チップポケット２７とインサート３１とを、ホブ回転軸方向に対向させることができる。これにより、ボルト３２や、このボルト３２を締め付け及び緩めるためのレンチ３３が、インサート３１を装着しようとする端部分割ホブ１１及び中間部分割ホブ１２と隣接した端部分割ホブ１１及び中間部分割ホブ１２に干渉することがないので、インサート３１の着脱作業性を向上させることができる。   Therefore, according to the throw-away hob 1 according to the present invention, the mounting interval of the insert 31 in the hob rotation direction is set to an angle at which 360 ° cannot be equally divided, and the number of turns of the worm 24 is set to less than one. Accordingly, as shown in FIG. 5, the tip pocket 27 and the insert 31 are rotated by the hob between the adjacent end divided hob 11 and the intermediate divided hob 12 and between the adjacent intermediate divided hobbs 12. It can be made to oppose to an axial direction. Accordingly, the bolt 32 and the wrench 33 for tightening and loosening the bolt 32 are adjacent to the end split hob 11 and the intermediate split hob 12 to which the insert 31 is to be attached, and the end split hob 11 and the intermediate split. Since there is no interference with the hob 12, the detachability of the insert 31 can be improved.

また、ウォーム２４の巻数を設定する際に、ウォーム２４の端面２４ａを、ホブ回転方向に隣接した取付座面２５間の中間位置よりも、ホブ回転方向上流側に配置することにより、端面２４ａが取付座面２５やその付近に配置されないため、インサート３１の取付剛性を向上させることができる。   Further, when setting the number of turns of the worm 24, the end surface 24a of the worm 24 is disposed upstream of the intermediate position between the mounting seat surfaces 25 adjacent in the hob rotation direction, so that the end surface 24a is Since it is not arranged on the mounting seat surface 25 or in the vicinity thereof, the mounting rigidity of the insert 31 can be improved.

更に、インサート３１のホブ回転方向の装着間隔を設定してから、ウォーム２４の巻数及びその端面２４ａの配置を設定することにより、ウォーム２４の巻数及びその端面２４ａの配置による制限を受けることなく、インサート３１を任意の装着間隔で配置することができる。これにより、インサート３１の配置の自由度を大きくすることができる。   Furthermore, by setting the mounting interval in the hob rotation direction of the insert 31 and then setting the number of turns of the worm 24 and the arrangement of its end face 24a, without being restricted by the number of turns of the worm 24 and the arrangement of its end face 24a, The inserts 31 can be arranged at arbitrary mounting intervals. Thereby, the freedom degree of arrangement | positioning of the insert 31 can be enlarged.

本発明は、歯切り時おけるインサートの振動を防止して、加工精度の向上を図るようにしたスローアウェイ式ホブに適用可能である。   INDUSTRIAL APPLICABILITY The present invention can be applied to a throw-away hob that prevents vibration of the insert during gear cutting and improves processing accuracy.
