Definitions
- the present invention relates to a method and an apparatus for machining a female screw into a hole made of a metal material having a hole for female screw machining.
- the internal thread constitutes one side of the screw, which is the most universal fastening element.
- a female screw is processed by a tabbing process.
- machining of a relatively large diameter female screw has not been generally performed by tapping.
- a cutting process using a single point tool is mainly used (for example, see Patent Document 1).
- the thread processing method that does not generate chips as well as the grooveless tap, which is effective may be applied to relatively large diameter products where the application of grooveless taps is not common. Conceivable.
- the radial load required for the male screw-shaped tool varies depending on conditions such as the desired effective length of the female screw, the hardness of the material, and the diameter of the male screw-shaped tool. For this reason, the radial load necessary for the male threaded tool is required to be at least 10 times that of a process for cutting with a single point tool (thread cutting tool).
- the male screw-like tool is very similar to the NC milling machine in which the rotation of the main shaft is stopped in terms of motion function, but the main shaft radial load (for example, 50 kNf or more) is much larger than the main shaft radial load allowed for a normal milling machine. )Is required.
- the radial load of the main shaft was 50 kNf or more. Therefore, it has not been possible to apply the threading method that does not generate chips using a conventional method and apparatus to a relatively large diameter product in which application of a grooveless tap is not common.
- the present invention was made in order to solve the problems of the conventional method, and its purpose is a female thread processing that does not generate chips as well as a grooveless tap that is effective for relatively small diameter screws.
- An object of the present invention is to provide a female thread processing method and apparatus capable of adapting to a relatively large diameter product in which application of a grooveless tap is not common.
- another object of the present invention is that it is possible to process internal threads without generating cutting chips and ignoring any obstacle such as a key groove provided in the inner diameter portion of the material hole. It is to provide a method and apparatus thereof.
- the internal thread processing method is a method of processing a female thread in a hole of a metal material having a hole for internal thread processing.
- the shape of the processed part is transferred to the inner periphery of the hole with the movement of only the above revolution, and the shape of the processed part is transferred to form a screw groove.
- the diameter of the hole is an intermediate diameter between a desired thread crest diameter and trough diameter.
- the male threaded tool has the same pitch as the female thread to be machined and a small diameter.
- the female thread processing device of the present invention includes a processing machine main body for gripping or fixing a metal material having a female thread processing hole, and an arc swinging by exerting a necessary pressing force on the processing machine main body. It has an X-axis-Y-axis table that can be controlled and a male-screw-like tool fixed on the X-axis-Y-axis table, and the male-screw tool fixed on the X-axis-Y-axis table does not rotate.
- a thread groove is formed by transferring the shape of the processed portion while successively pressing the processed portion of the male screw-like tool on the inner periphery of the hole with a motion of only revolution on a certain horizontal plane.
- the present invention includes a control device that controls the X-axis-Y-axis table so that the processing machine main body swings in a circular arc while exhibiting a necessary pressing force.
- the male thread-like tool for forming a desired female thread by transfer must naturally have the same pitch length as the desired female thread.
- the screw diameter of the male screw-like tool is smaller than the screw diameter of the desired female screw, the twist angle formed by the screw thread is larger than that of the female screw. For example, if the diameter of the male threaded tool is half that of the female thread diameter, the twist angle is almost doubled. In order to overcome this gap and form the same pitch as the male thread-like tool on the female thread, it is necessary to ensure a constant slip at the contact portion, that is, to firmly synchronize with each other.
- the measure taken by the present invention was to maintain the above-mentioned synchronization firmly as a result.
- the diameter difference between the female screw and the male screw-shaped tool is large, the male screw-shaped tool is released from the processed female screw at an early stage and has little interference with the formed female screw.
- the occurrence of problems does not become apparent, but in reality, the occurrence of inclination due to the bending of the male screw-shaped tool becomes remarkable, and it becomes a weak point for transfer molding of a female screw with good accuracy. If the diameter difference between the female screw and the male screw-shaped tool is reduced, the inclination of the male screw-shaped tool is reduced.
- the X-axis / Y-axis table of the female thread processing machine of the present invention has a very short stroke in which only the difference between the desired female thread radius and the male thread radius is within the operating range.
- it was designed in a direction that minimizes the height difference in the Z direction between the X-axis rail and the Y-axis rail to ensure the necessary rigidity.
- the female screw hole is a blind hole or the tact during mass production
- a cantilevered shaft is convenient for male screw tools.
- the male screw tool is supported and fixed at two points straddling the female thread processing region. In that case, a machine in which two similarly designed X-axis and Y-axis tables are linked may be required.
- the present invention is a processing machine that ensures the necessary rigidity by designing with a short stroke and reducing the height difference in the Z direction between the X-axis rail and the Y-axis rail, and succeeded in overcoming the twist angle gap.
- the generated radial load is large, in principle, it is possible to complete machining of female threads within a few rotations, regardless of the number of screw threads and the effective screw length, even if they are operated in a single rotation or sequential machining. .
- the present invention does not suffer from the processing of chips generated by cutting with a single point tool (thread cutting tool) even for a relatively large diameter female thread for which tapping is not common. Further, from the viewpoint of machining principle, it is possible to obtain the merit that machining is completed in a short time, as symbolized by a simple movement in which the male threaded tool revolves on a single horizontal plane.

Abstract
Description
従来、メネジはタッビング加工によって加工されることが知られている。
しかし、比較的大径のメネジの加工は、タッピング加工では、一般的に行われていなかった。
比較的大径のメネジの加工法は、シングルポイント工具(ねじ切りバイト)による切削加工が主流(例えば、特許文献1参照)である。
なお、このメネジ切削法として、例えば、通常、チェザーと呼ばれるねじ切削用刃物を管体の被切削面に押し当て、管体を回転させつつ管軸方向に前後進させる方法が採用されている。
また、ネジ山の数に対応した工具の回転を必要とする(例えば、特許文献1参照)ため、その加工時間は自ずから限界があった。
このように、主軸のラジアル荷重が50kNf以上となる機械は、存在しなかった。
従って、従来工法及び装置を用いて、切り屑を発生しないネジ加工法を溝なしタップの適用が一般的でない比較的大径品に適応することはできなかった。
また、本発明の別の目的は、切削切り屑を発生させず、素材穴内径部に設けられた例えばキー溝のごとき障害物があってもこれを無視してメネジを加工することが可能な方法及びその装置を提供することにある。
また、本発明において、穴の径は、所望するネジの山径と谷径の中間径である。
また、本発明において、オネジ状工具は、加工しようとするメネジとピッチが同一で、径が小さい。
また、本発明は、X軸-Y軸テーブルを、加工機本体に対し、必要な押圧力を発揮して円弧揺動するように制御する制御装置を備える。
メネジとオネジ状工具との径差が少なくなれば、オネジ状工具の傾斜発生は少なくなる。しかし、メネジとオネジ状工具との係合を解くまでの公転角度は大きくなり、メネジとオネジ状工具との干渉、係合の距離が長くなる。従って、オネジ状工具公転の抵抗が増す。この抵抗にも拘わらず、スリップ-スティック現象を伴わない滑らかな公転を保障するのには、加工機の剛性を高める以外にない。
また、メネジ穴が止り穴であるとか、量産時のタクトを考えると、オネジ状工具は片持ち軸が便利である。要求される転写成形に必要なスラスト荷重が高い場合は、メネジ加工域を跨ぐ2点でオネジ状工具を支持固定する。その場合は、同様設計のX軸-Y軸テーブルを2台連動させた機械が必要になることもある。
本発明は、タッピング加工が一般的でない、比較的大径のメネジに対しても、シングルポイント工具(ねじ切りバイト)による切削加工で発生する切り屑の処理に悩まされることがない。また、加工原理から見ても、オネジ状工具が単一水平面上で公転するのみというシンプルな動きに象徴されるように、短時間で、加工が完了するというメリットを得ることができる。
図1は、本発明の一実施形態に係るメネジ60の加工法を示し、図2は、図1の要部を示す。図3~図5は、本実施形態に係るメネジ60の加工法に用いるメネジ加工装置1を示す。なお、図2には要素部分のみを表している。
本実施形態に係るメネジ加工装置1は、加工機本体10と、この加工機本体10に搭載されるX軸テーブル20と、このX軸テーブル20上にY軸テーブル33が位置するようにX軸テーブル20に固定されるY軸フレーム30とを備えている。
加工機本体10の上面には、穴51を有する金属製の素材50を固定する素材固定台11が配置されている。素材固定台11は、金属製の素材50を嵌入させるための穴12を備えている。金属製の素材50は、例えば、周囲に3カ所の穴52を備えている。素材固定台11は、穴12に金属製の素材50を嵌入後に、締結ボルト53によって金属製の素材50を固定するためのねじ穴13を備えている。
Y軸フレーム30は、このX軸テーブル20上に位置するようにX軸テーブル20に固定されている。Y軸フレーム30は、X軸テーブル20と同様にサーボモータ(Y軸用モータ)31によって回転する推進ネジ部32を介してY軸上を移動するY軸テーブル33を備えている。この際、Y軸テーブル33は、X軸テーブル20に設けた例えばクロスローラガイドなどの案内部材34に沿ってY軸方向に移動する。
以上のように、Y軸フレーム30は、X軸テーブル20上にY軸テーブル33が位置するようにX軸テーブル20に固定されるので、X軸テーブル20上に位置するように加工機本体10に固定されている素材固定台11とY軸テーブル33との距離(図2の紙面の上下方向、即ちZ軸方向)は不変である。
先ず、図1、図2に示すように、オネジ状工具35は、加工しようとするメネジ60とピッチが同一で、径が加工しようとするメネジ60より小さいネジ形状を為す加工部35aを備えている。オネジ状工具35は、Y軸テーブル33上に締結ネジ37によって固定される。
次に、金属製の素材50が、オネジ状工具35の上方から穴51を挿通するように、素材固定台11の穴12に嵌入された後、金属製の素材50が締結ネジ53によって素材固定台11上に固定される。
次に、制御装置40は、Y軸テーブル33が式(X2+Y2=R2)により画かれる軌跡を踏襲するようにサーボモータ(X軸用モータ)21及びサーボモータ(Y軸用モータ)31の動きを制御する。
次に、制御装置40は、例えば、図1に示すように、金属製の素材50の穴51の点Wにオネジ状工具35の点Wが位置するように、X軸テーブル20及びY軸テーブル33をそれぞれX軸方向及びY軸方向に移動させる。
この間、金属製の素材50とオネジ状工具35はZ軸方向には相対移動しないし、またZ軸方向(図2の紙面の上下方向)には相対移動する必要もない。
また、上記実施形態では、金属製の素材50を締結ボルト53で素材固定台11に固定したが、本発明はこれに限らず、金属製の素材50を固縛手段を介して素材固定台11に固定しても良い。
また、上記実施形態では、オネジ状工具35が金属製の素材50の穴51を一回転することによってメネジ60を成形する場合について説明したが、本発明はこれに限らず、制御装置40は、オネジ状工具35が金属製の素材50の穴51を複数回転するように制御することも可能である。
さらにまた、ボールネジ用の1条毎にクローズとなるループ溝においてはボール循環用バイパスなど一部の溝深さが他の部分より深い溝も工具次第で成形可能である。勿論、そのクロースドループ溝が複数条存在する内径面も同時に成形可能である。
図8、図9は、S字形バイパス82を設けた雌循環路81を有するボールネジ用のナット部材80を加工するオネジ状工具70を示す。S字形バイパス82を加工する加工部72は雌循環路81を形成する加工部71よりも外方に突出している。
また、ナット部材80を加工する前の金属製の素材には、上記実施形態における穴51を有する金属製の素材50と同様に、ナット部材80の穴に見合った穴を有する金属製の素材を用意し、素材固定台11に固定される。
本例においても、加工法は上記実施形態と同じである。
