Description
【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、旋盤或いは自動単能盤等を用いて、ワーク
の外周に形成されたフランジの両端面とこれに接するワ
ーク外径面を同時加工することを可能ならしめた複合工
具に関する。[Detailed Description of the Invention] [Industrial field of application] This invention uses a lathe or an automatic single-purpose lathe to simultaneously define both end surfaces of a flange formed on the outer periphery of a workpiece and the outer diameter surface of the workpiece in contact with the flange. The present invention relates to a compound tool that can be machined.

面（ａ部）、及び外径面の他の一部とこれに連なるフラ
ンジの他面（ｂ部）の２個所が被加工面となっている。FIG. 4 shows an example of an object to be machined by the tool of the present invention. The illustrated work A has a flange F in the middle of the outer diameter surface in the longitudinal direction, and a part of the outer diameter surface and one surface (a part) of the flange continuous with this, and another part of the outer diameter surface and this. Two points on the other surface (section b) of the continuous flanges are the surface to be processed.

工する方法が採用されているが、これ等の方法には下記
の課題がある。To machine parts a and b of such a work, as shown in FIG. 5, two independent tools 20, 21 are attached to a turret head, etc., the positions of the tools are exchanged, and each surface is cut separately. Method, as shown in FIG. 6, a tool is installed on the side opposite to the front side of the work A, and each surface is simultaneously machined by a single-purpose board, and further, as shown in FIG. 7, on the same plane. When the processing chips 22 and 23 on each surface are arranged side by side, and when the intervals are small, two chips are simultaneously clamped with a single presser foot 24 and two surfaces are processed simultaneously. The method has the following problems.
第５図の方法は、複数の刃物台を必要とし、しかも、汎
用旋盤を用いると加工時間が他の２つの方法に比較して
２倍になる。The method of FIG. 5 requires a plurality of turrets, and when a general-purpose lathe is used, the processing time is doubled as compared with the other two methods.
また、第６図の方法は、ワークの両側に刃物台を必要と
し、工具も正バイト、逆バイトの２種を必要とする。Further, the method of FIG. 6 requires a tool rest on both sides of the work and requires two kinds of tools, a normal cutting tool and a reverse cutting tool.

点もあり、加工精度が保証されない。On the other hand, the method of FIG. 7 requires only one tool post and one tool, which is advantageous in terms of processing time, but since one tip is used to clamp two chips with variations in dimensional accuracy, It is very difficult to clamp the tip stably with the same pressure, and the tip easily shifts. For the same reason, the set interval between chips tends to be incorrect. In addition, since a main component force in the same direction acts on the two chips, there is a fatal defect that the tool is easily chattered, and the machining accuracy is not guaranteed.

決でき、チップ間の間隔調整も可能になる。Incidentally, Japanese Utility Model Publication No. 57-7446 discloses a tool in which two cutting tools are combined so that the distance between the blades can be adjusted.
Japanese Utility Model Laid-Open No. 51-15792 discloses a tool in which a main bite and an auxiliary bite are combined at an angle. By combining these techniques, it is possible to solve the problem of chip shift, the problem of coincidence of the action directions of the main cutting force components on the two blade portions, and the adjustment of the interval between the chips becomes possible.
しかしながら、２本のバイトを組合わせるこれ等の工具

第２バイトの平行度を確保し難い。However, in these tools that combine two cutting tools, the fixed position of each cutting tool is far from the cutting edge,
It is not suitable for heavy cutting because the shank easily bends between the cutting edge and the fixed position. If the cutting load is large, the stability of processing cannot be maintained and the processing accuracy will decrease. In addition, the actual public Sho 57-7446
No. 3 uses three screws to adjust the blade separation distance, so
It is difficult to secure the parallelism of the second bite.
さらに、この種の工具では、スローアウェイ式工具の利
点（切刃の簡単かつ経済的再生）も生かされない。Furthermore, this type of tool does not take advantage of the advantages of throw-away tools (simple and economical reproduction of cutting edges).
この考案の目的は、上述の課題を無くした複合加工工具
を提供することにある。An object of the present invention is to provide a composite machining tool that eliminates the above problems.

ンプして装着する。In order to utilize the advantages of the method shown in FIG. 7, the combined machining tool of the present invention is provided with the outer diameter surface of the work and the first cutting edge tip for cutting one end surface of the different diameter portion rising from the outer diameter surface, and the outer diameter surface. A second cutting edge tip that cuts the work outer diameter surface at a separate place and the other end surface of the different diameter portion rising from the work is attached to the same tool body. The tool body has a structure in which two two-face restraint type seats, which are displaced in the axial direction of the workpiece and are relatively inclined in the circumferential direction of the workpiece by 30 ° to 45 °, are provided on the outer periphery of the tip portion. . Further, each chip is attached as follows in order to eliminate the drawbacks of the method shown in FIG. That is, the second cutting edge tip is clamped and attached to one of the seats provided on the tool body with a presser foot. Further, an adjusting unit having a work axis direction fine adjustment mechanism for the first cutting edge tip is attached to the other seat, and the first cutting edge tip is clamped and attached to the seat provided in this unit with a presser foot.
上述した構成にすると刃物台、工具が１つでよく、２つ
のチップが２面を同時加工するので加工時間も半減す
る。With the configuration described above, only one tool post and one tool are required, and two chips simultaneously machine two surfaces, so the machining time is reduced by half.

生かされる。Further, two seats are provided on the outer periphery of the tip of the tool body, and two chips are clamped with presser foot and separately attached to one of the seats and the adjustment unit to be mounted on the other seat, so that they act on each chip. The main cutting force can be stably received by the tool body, and the stability of the stationary tip is also improved by stabilizing the clamp, enabling powerful cutting. In addition, only the tip can be replaced, and the advantage of the throw-away tool can be used.
さらに、２つのチップ間の間隔を微調整機構で調整でき
るので、チップのセッティング時の位置精度も高め得
る。Further, since the interval between the two chips can be adjusted by the fine adjustment mechanism, the positional accuracy at the time of setting the chips can be improved.
このほか、２つのチップを30〜45°の角度で周方向に変
位させたことによってそれ等のチップに作用する主分力
の向きが変わり、このこともビビリ抑制に効果を奏す
る。In addition, by displacing the two chips in the circumferential direction at an angle of 30 to 45 °, the direction of the main component force acting on these chips changes, which also has an effect of suppressing chattering.
第１図乃至第３図にこの考案の一実施例を示す。 1 to 3 show one embodiment of the present invention.

変に固定してある。In FIG. 1, 1 is a tool main body, and two throw-away tips 2 and 3 are attached to the outer peripheral portion of the tip of the main body. The two chips are displaced and arranged in the circumferential direction of the work A at an angle of θ = 30 to 45 °. Further, the tip 2 is set on a seat 4 formed on the outer periphery of the tip of the main body, tightened with a presser foot 5, and fixed in place.

に一定に保たれる。On the other hand, the tip 3 is fixed to a seat 7 formed at the tip of the adjustment unit 6 with a presser foot 8 to enable position adjustment in the work axis direction. That is, the unit 6 is θ with respect to the seat 4.
It is mounted on another seat at the tip of the tilted main body, and there is a play (not shown) between the fixing bolt 9 of the unit 6 for the main body 1 and the bolt hole through which this bolt is passed, so loosen the bolt 9. After that, when the adjusting screw 10 screwed into the main body is rotated, the tip 3 is slightly moved in the axial direction together with the tip 3. The distance l between the chips 2 and 3 due to the movement
(See FIG. 2) can be changed to adjust the thickness dimension of the flange or the like on the outer circumference of the work. Since the unit 6 slides in contact with the two faces of the seat of the main body, the posture of the tip 3 is always kept constant.

工具は一本で良く、加工能率も向上する。第４図のＢは
チャックで、ワークはこれに掴まれて回転している。As can be seen from FIG. 3 and FIG. 4, the exemplary tool constituted as described above is cut into the work A at a position where the tips 2 and 3 are angularly displaced by θ, and the a and b parts are cut at the same time. Therefore,
Only one tool is needed, and machining efficiency is improved. B of FIG. 4 is a chuck, and the work is gripped by the chuck and is rotating.

る。It should be noted that the lower limit of θ is set to 30 ° because if it is less than this, it becomes difficult to clamp the chips 2 and 3 independently, and if the main component force acting on both chips approaches the same direction too much This is due to the easy blurring. Also, the upper limit of θ is 45
The reason for setting the angle is to avoid making the tool complicated and large.
以上説明したように、この考案では、２つの切刃チップ

効果がある。As described above, according to the present invention, two cutting blade tips are arranged with their phases changed in the circumferential direction of the work, and one tip is supported by the fine adjustment unit, so that the method shown in FIG. Since all the problems concerning the stability of stationary inserts, the problem of adjusting the position and spacing of the cutting edge, and the problem of blurring due to the main component force of the main body have been solved, economic efficiency, processing efficiency,
There is an effect that it becomes possible to satisfy all three of the processing accuracy.
特に、本体は、２つのチップを刃部の近くで支えるよう
にしてあるので、切削力で撓む心配がなく強力な切削に
耐える。また、スローアウェイ式工具の形態を踏襲して
いるので、これによる経済効果も期待できる。In particular, since the main body supports the two chips near the blade portion, there is no fear of bending due to the cutting force, and strong cutting can be endured. Further, since it follows the form of the throw-away type tool, an economic effect due to this can be expected.
