Description

【０００１】
【発明の属する技術分野】
本発明は、ワークに多面加工を行う切削装置、特に角柱状のワークの各面に加工を行う切削装置に関するものである。
【０００２】
【従来の技術】
従来は、ワークに多面加工を行うには、ワークテーブル上に治具を載置してワークを固定して、加工工具により一面に加工を施すと、前記固定を解いて他の面を加工工具に対向させて再び固定して加工するというように、段取り替えをしていた。
【０００３】
【発明が解決しようとする課題】
しかし、段取り替えを加工する面の数に応じて行わなければならず、またワークの治具上へのセット時に生じる誤差がそのままワークへの加工精度に影響を与えるものであるから、作業者にとっては相当の手間と時間が必要であった。
【０００４】
そこで本発明は、上記の点に鑑み、ワークに多面加工を行う際の作業者にとって手間と時間が大幅に短縮できる切削装置を提供することを目的とする。
【０００５】
【課題を解決するための手段】
このため本発明は、平面方向及び上下方向に移動可能で回転によりワークに切削加工を行う加工工具と、該加工工具の回転軸と直交する軸線を回転中心軸とするワーク割出し軸を所定角度に割出すもので前記ワークの一側面を把持する第１位置決めホルダーを有するワーク割出し手段と、前記ワーク割出し軸に対向して設けられ前記ワークの他側面を把持する第２位置決めホルダーを有して前記ワーク割り出し手段に前記ワークを押圧して把持するワーク押え手段とを備え、両側面に所定の長さを有し且つ対向斜面の間隔が先端に向って狭くなるような奥に行くに従って開口面積が狭い横嵌合溝及び縦嵌合溝が形成された前記ワークを前記ワーク割出し手段に前記ワーク押え手段が押圧把持する際に前記横嵌合溝及び縦嵌合溝に案内されながら嵌合する対向斜面の間隔が先端に向って狭くなる横突部及び縦突部を前記第１及び第２位置決めホルダーの対向する面に形成し、前記横突部及び縦突部が前記横嵌合溝及び縦嵌合溝に嵌合する際に、前記横突部及び縦突部の先端が前記横嵌合溝及び縦嵌合溝を形成する面に接することなく且つ前記第１及び第２位置決めホルダーの前記横突部及び縦突部が形成された側面がこの横突部及び縦突部を除き前記ワークに接することなく、該横突部及び縦突部の各斜面が前記横嵌合溝及び縦嵌合溝の各斜面に接することにより前記ワークを位置決めすることを特徴とする。
【０００６】
また第２の発明は、第１の発明において、前記第１及び第２位置決めホルダーの対向する面に形成された前記横突部及び縦突部の高さを前記ワークの両側面に形成された前記横嵌合溝及び縦嵌合溝の深さより短く形成したことを特徴とする。
【０００９】
【発明の実施の形態】
以下図１乃至図７に基づき、本発明の第１の実施の形態について説明する。先ず、図１及び図２に基づき説明すると、１は切削装置における角柱状のワーク２に切削加工を行う加工工具で、Ｘ軸駆動モータ、Ｙ軸駆動モータ及びＺ軸駆動モータ（ともに図示せず）により平面方向及び上下方向に移動可能で、かつθ軸駆動モータ（図示せず）により鉛直軸を支点として回転可能であり、この回転によりワーク２の各面に切削加工を行う。
【００１０】
３は上面を平面とする平面状のワ−クテーブルで、このワークテーブル３にはワーク割出し手段４及びワーク押え手段５とが対向するように所定間隔を存して、例えばボルト６などで複数箇所固定されるが、前記ワーク押え手段５はワークテーブル３に沿ってスライドして移動でき、ワーク２のサイズに合わせて所定位置に前述の如く固定される。
【００１１】
前記ワーク割出し手段４は、前記加工工具１の回転軸と直交する軸線を回転中心軸とするワーク割出し軸７をプログラムされた数値制御により所定角度に割出すもので、このワーク割出し軸７の前端には前記ワーク２の一側面を把持する第１位置決めホルダー８を有する。
【００１２】
また、前記ワーク押え手段５は前記ワーク割出し軸７に対向してその延長線上に設けられた油圧シリンダ９の回転可能なロッド９Ａが左右に移動制御され、このロッド９Ａの前端には前記ワーク２の他側面を把持する第２位置決めホルダー１０を有する。尚、油圧シリンダ９に代えてエアシリンダを用いてもよい。
【００１３】
図３及び図４において、１１は前記ワーク割出し手段４及びワーク押え手段５とでワーク２の両側面を挟んで把持する際に供するワークセット治具で、一対の治具１２、１２から構成される。各治具１２は平面部１３を有すると共に、該平面部１３の中間部には複数の階段を有する接合部１４が突設されている。そして、対で使用して、その接合部１４、１４の階段を所定の位置で互いに接合させることにより高さレベルを調節できる。即ち、前記ワークテーブル３に一方の治具１２の平面部１３を載置させ、接合部１４、１４の階段同士を所定位置で接合させるようにした上で、他方の治具１２の平面部１３上に前記ワーク２を載置させて、前記ワーク割出し手段４及びワーク押え手段５とで相当の重量を有するワーク２の両側面を挟んで把持する際に供するものである。
【００１４】
次に、図５に示すように、前記ワーク２の前記両側面には側面両端部まで延びた１条の横嵌合溝１５と、この横嵌合溝１５を横切るように所定間隔を存して形成されると共に一端が側面端部まで延びる複数の縦嵌合溝１６とが形成される。これらの横嵌合溝１５及び縦嵌合溝１６の断面形状は、図７に示すように、台形状を呈しており、対向する面が互いに奥に行くに従って近づくようにテーパ状に形成され、手前の開口面積を広く、奥に行くに従って開口面積を狭く形成する。
【００１５】
そして、前記ワーク割出し手段４及びワーク押え手段５の第１及び第２位置決めホルダー８、１０には、前記ワーク２を押圧把持する際に、前記横嵌合溝１５及び縦嵌合溝１６のテーパ面に案内されながら嵌合する複数の横突部２０及び縦突部２１を形成する。
【００１６】
詳述すると、前記横突部２０及び縦突部２１共に断面が台形状を呈しており、前記横嵌合溝１５及び縦嵌合溝１６に前記横突部２０及び縦突部２１が嵌合しても、これらの横突部２０及び縦突部２１の高さは前記横嵌合溝１５及び縦嵌合溝１６の深さより短く形成されているために、横突部２０及び縦突部２１の先端面（台形の上底を形成する面）が前記横嵌合溝１５及び縦嵌合溝１６を形成する面に接することはなく、台形の両斜辺を形成する面が接する。
【００１７】
以上のように構成したために、図３に示すように、先ず前記ワークテーブル３に一方の治具１２の平面部１３を載置させ、接合部１４、１４の階段同士を所定位置で接合させるようにした上で、他方の治具１２の平面部１３上に前記ワーク２を載置させて、前記ワーク割出し手段４に向けてワーク押え手段５の第２位置決めホルダー１０を油圧シリンダで移動させることにより、相当の重量を有するワーク２の両側面を第１及び第２位置決めホルダー８、１０で挟んで把持する。
【００１８】
このとき、ワーク２の横嵌合溝１５及び縦嵌合溝１６の対向斜面の間隔が先端に向って狭くなるようなテーパ面に案内されながら、第１及び第２位置決めホルダー８、１０の横突部２０及び縦突部２１が夫々進み、横突部２０及び縦突部２１の先端面（台形の上底を形成する面）が前記横嵌合溝１５及び縦嵌合溝１６を形成する面に接することなく、また第１及び第２位置決めホルダー８、１０の横突部２０及び縦突部２１が形成された側面がこの横突部２０及び縦突部２１を除き前記ワークに接することなく、横突部２０及び縦突部２１の対向斜面の間隔が先端に向って狭くなる台形の両斜辺を形成する面が横嵌合溝１５及び縦嵌合溝１６のテーパ面に接して、確実に且つ位置決めの精度が良好に嵌合する（図６及び図７参照）。
【００１９】
この後、治具１２、１２をワークテーブル３上から外し、運転スイッチの操作により、前記ワーク割出し手段４及びワーク押え手段５により把持され、前記ワークテーブル３と接触していない状態でワーク２の一面に加工工具１により切削加工を行う。この場合に、前記ワークテーブル３上で固定して加工場合に比して、加工工具１の磨耗が少ない。
【００２０】
そして、この面への切削を終了した場合には、前記ワーク割出し手段４は、ワーク割出し軸７をプログラムされた数値制御により所定角度に割出した後、他の面にも加工工具１により切削加工を行い、以下同様に、所定角度ワーク２を回転させては切削加工を行うことができる。尚、ワーク２の両側面を第１及び第２位置決めホルダー８、１０で挟んで把持するが、そのワーク２への接触面はわずかであるために、該ワーク２の両側面にも加工を行うことができ、角柱状を呈するワーク２の６面全てに加工できるものである。
【００２１】
尚、ワーク２の横嵌合溝１５及び縦嵌合溝１６の断面形状を、台形状とするが、対向する面のうち一方の面が奥に行くに従って他方の面に近づくようにテーパ状に形成すると共に他方の面はワーク２の側面と直角となるように形成し、手前の開口面積を広く、奥に行くに従って開口面積を狭く形成し、また同様に、第１及び第２位置決めホルダー８、１０の横突部２０及び縦突部２１も断面が台形状を呈しており、前記ワーク２の横嵌合溝１５及び縦嵌合溝１６の断面形状に合わせて、台形の斜辺を形成する一方の面は第１及び第２位置決めホルダー８、１０の側面とは直角な面とし、他方の面は傾斜した面としてもよい。
【００２２】
次に、図８乃至図１０に示すように、第２の実施の形態について説明する。この実施形態は、ワーク２には嵌合溝を形成せずに、前述したように治具１１、１１を用いて、前記ワーク割出し手段４に前記ワーク２をワーク押え手段５が押圧把持する際に、前記第１及び第２位置決めホルダー８、１０には前記ワーク２の側面に食い込む円錐状の複数の食込部２５と該食込部２５の周囲に凹部２６を形成するものである。
【００２３】
即ち、前記食込部２５は断面が三角形状を呈して、その頂部は前記第１及び第２位置決めホルダー８、１０の側面より高い位置となるよう突出して形成すると共に、該食込部２５の周囲には凹部２６を形成する。また、この食込部２５と凹部２６とは、夫々所定間隔を呈して複数形成する。
【００２４】
このように形成したために、前記ワーク割出し手段４に前記ワーク２をワーク押え手段５が押圧把持する際には、図９の左方に示した状態から中央に示す状態のように、前記第１及び第２位置決めホルダー８、１０の側面がワーク２の側面に当接するまで、前記食込部２５が前記ワーク２の側面に食い込むと共にこの食い込みにより盛り上がった部分２７が生じても前記凹部２６に逃げることができ、この盛り上がった部分２７を吸収できるものである。
【００２５】
尚、図１１に示すように、前記ワーク割出し手段４に前記ワーク２をワーク押え手段５が完全に押圧把持する前に、前記第１及び第２位置決めホルダー８、１０が上下からワーク２を軽く押圧するようにしてもよいが、以下この実施形態について詳述する。前記第１及び第２位置決めホルダー８、１０の前面下部に支承部３０を形成し、前面には前記食込部２５及び凹部２６を形成し、一部切除した前端上部にはボルト３１で締め付けることにより前記支承部３０で支承されたワーク２を上方から押圧片３２で押圧して、前記ワーク割出し手段４に前記ワーク２をワーク押え手段５が完全に押圧把持する際にズレないようにする。
【００２６】
以上のように、支承部３０と押圧片３２とで上下方向にズレないようにした状態のワーク２を、前記ワーク割出し手段４にワーク押え手段５が押圧把持する際には、上下方向の押圧力よりはるかに大きな押圧力で、前述したように前記第１及び第２位置決めホルダー８、１０の側面がワーク２の側面に当接するまで、前記食込部２５が前記ワーク２の側面に食い込む。
【００２７】
なお、この実施形態は、第２の実施形態ばかりか第１の実施形態にも適用できる。また、ワーク２の重量に応じて押圧把持する圧力を調整するように構成するが、前記第１及び第２位置決めホルダー８、１０の横突部２０及び縦突部２１が前記ワーク２の横嵌合溝１５及び縦嵌合溝１６に嵌合してワーク２を押圧把持したり、前記第１及び第２位置決めホルダー８、１０の前記食込部２５がワーク２の面に食い込むことによりワーク２を押圧把持する実施形態によれば、この嵌合や食い込みをしない形態に比べて、押圧力が少なくて済み、従って油圧シリンダ９の押圧能力が小さいものでも足りるから安価に作製することができる。
【００２８】
以上本発明の実施態様について説明したが、上述の説明に基づいて当業者にとって種々の代替例、修正又は変形が可能であり、本発明はその趣旨を逸脱しない範囲で前述の種々の代替例、修正又は変形を包含するものである。
【００２９】

以上のように本発明は、ワークに多面加工を行う際の作業者にとって手間と時間が大幅に短縮できる切削装置を提供することができる。

[0005]
[Means for Solving the Problems]
Therefore, the present invention provides a machining tool that is movable in a plane direction and a vertical direction and that cuts a workpiece by rotation, and a workpiece indexing axis that has an axis perpendicular to the rotation axis of the machining tool as a rotation center axis at a predetermined angle. A workpiece indexing means having a first positioning holder for gripping one side surface of the workpiece and a second positioning holder provided facing the workpiece indexing shaft and gripping the other side surface of the workpiece. The work indexing means includes a work pressing means that presses and grips the work, and has a predetermined length on both side surfaces and the distance between the opposing inclined surfaces becomes narrower toward the tip. When the work holding means presses and grips the work formed with the horizontal fitting groove and the vertical fitting groove having a small opening area on the work indexing means, it is not guided to the horizontal fitting groove and the vertical fitting groove. But Spacing opposite slope which fit forms a horizontal projection and vertical projection narrows toward the tip on opposite sides of said first and second positioning holders, the horizontal projection and vertical projection is fitted the lateral When fitting into the mating groove and the vertical fitting groove, the ends of the horizontal protrusion and the vertical protrusion do not contact the surface forming the horizontal fitting groove and the vertical fitting groove, and the first and second The side surfaces of the positioning holder on which the horizontal protrusions and the vertical protrusions are formed do not contact the workpiece except for the horizontal protrusions and the vertical protrusions, and the inclined surfaces of the horizontal protrusions and the vertical protrusions are the lateral fittings. The workpiece is positioned by contacting each inclined surface of the groove and the vertical fitting groove.
[0006]
According to a second aspect of the present invention, in the first aspect, the height of the lateral protrusion and the vertical protrusion formed on the opposing surfaces of the first and second positioning holders is formed on both side surfaces of the workpiece. It is characterized by being formed shorter than the depth of the horizontal fitting groove and the vertical fitting groove.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. First, referring to FIGS. 1 and 2, reference numeral 1 denotes a processing tool for cutting a prismatic workpiece 2 in a cutting apparatus, and an X-axis drive motor, a Y-axis drive motor, and a Z-axis drive motor (both not shown). ), And can be rotated about a vertical axis by a θ-axis drive motor (not shown). By this rotation, each surface of the workpiece 2 is cut.
[0010]
Reference numeral 3 denotes a flat work table having a flat upper surface. The work table 3 is provided with a predetermined interval so that the work indexing means 4 and the work pressing means 5 are opposed to each other, for example, with a bolt 6 or the like. The work holding means 5 can be slid and moved along the work table 3 and is fixed at a predetermined position according to the size of the work 2 as described above.
[0011]
The workpiece indexing means 4 indexes a workpiece indexing shaft 7 having an axis perpendicular to the rotation axis of the machining tool 1 as a rotation center axis at a predetermined angle by programmed numerical control. 7 has a first positioning holder 8 for gripping one side surface of the workpiece 2.
[0012]
In addition, the work holding means 5 is controlled so that a rotatable rod 9A of a hydraulic cylinder 9 provided on an extension line thereof facing the work indexing shaft 7 is moved to the right and left. 2 has a second positioning holder 10 for gripping the other side surface. In place of the hydraulic cylinder 9, an air cylinder may be used.
[0013]
3 and 4, reference numeral 11 denotes a work setting jig provided when the work indexing means 4 and the work pressing means 5 hold the both side surfaces of the work 2. The work setting jig includes a pair of jigs 12 and 12. Is done. Each jig 12 has a flat surface portion 13, and a joint portion 14 having a plurality of steps is projected from an intermediate portion of the flat surface portion 13. The height level can be adjusted by using the pair and joining the stairs of the joints 14 and 14 at a predetermined position. That is, the planar portion 13 of one jig 12 is placed on the work table 3 and the stairs of the joining portions 14 and 14 are joined at a predetermined position, and then the planar portion 13 of the other jig 12 is joined. The workpiece 2 is placed on the workpiece and provided when the workpiece indexing means 4 and the workpiece pressing means 5 hold the workpiece 2 with both sides of the workpiece 2 having a considerable weight.
[0014]
Next, as shown in FIG. 5, a single horizontal fitting groove 15 extending to both side end portions of the both sides of the work 2 and a predetermined interval so as to cross the horizontal fitting groove 15 exist. And a plurality of vertical fitting grooves 16 having one end extending to the side end portion. As shown in FIG. 7, the cross-sectional shapes of the lateral fitting grooves 15 and the vertical fitting grooves 16 are trapezoidal, and are formed in a tapered shape so that opposing surfaces approach each other as they go deeper. The opening area in front is wide, and the opening area is narrowed toward the back.
[0015]
The first and second positioning holders 8 and 10 of the workpiece indexing means 4 and the workpiece holding means 5 are formed with the lateral fitting grooves 15 and the vertical fitting grooves 16 when the workpiece 2 is pressed and held. A plurality of lateral protrusions 20 and vertical protrusions 21 that are fitted while being guided by the tapered surface are formed.
[0016]
In detail, both the horizontal protrusion 20 and the vertical protrusion 21 are trapezoidal in cross section, and the horizontal protrusion 20 and the vertical protrusion 21 are fitted in the horizontal fitting groove 15 and the vertical fitting groove 16. Even so, since the height of the horizontal protrusion 20 and the vertical protrusion 21 is shorter than the depth of the horizontal fitting groove 15 and the vertical fitting groove 16, the horizontal protrusion 20 and the vertical protrusion The front end surface of 21 (the surface forming the upper base of the trapezoid) does not contact the surfaces forming the horizontal fitting grooves 15 and the vertical fitting grooves 16, but the surfaces forming both oblique sides of the trapezoid.
[0017]
Since it comprised as mentioned above, as shown in FIG. 3, the flat part 13 of one jig | tool 12 is first mounted in the said work table 3, and the stairs of the junction parts 14 and 14 are joined in a predetermined position now. After that, the workpiece 2 is placed on the flat surface portion 13 of the other jig 12, and the second positioning holder 10 of the workpiece pressing means 5 is moved by the hydraulic cylinder toward the workpiece indexing means 4. Thus, both side surfaces of the workpiece 2 having a considerable weight are sandwiched and held between the first and second positioning holders 8 and 10.
[0018]
At this time, the first and second positioning holders 8 and 10 are laterally guided while being guided by a tapered surface such that the distance between the opposing inclined surfaces of the horizontal fitting groove 15 and the vertical fitting groove 16 of the workpiece 2 becomes narrower toward the tip. The protrusions 20 and the vertical protrusions 21 respectively advance, and the front end surfaces of the horizontal protrusions 20 and the vertical protrusions 21 (surfaces forming the upper base of the trapezoid) form the horizontal fitting grooves 15 and the vertical fitting grooves 16. The side surfaces of the first and second positioning holders 8 and 10 where the lateral protrusions 20 and the vertical protrusions 21 are formed are in contact with the workpiece except for the lateral protrusions 20 and the vertical protrusions 21 without contacting the surfaces. The surface forming the trapezoidal hypotenuses in which the distance between the opposing inclined surfaces of the horizontal protrusion 20 and the vertical protrusion 21 narrows toward the tip is in contact with the tapered surfaces of the horizontal fitting groove 15 and the vertical fitting groove 16; It fits reliably and with good positioning accuracy (see FIGS. 6 and 7) .
[0019]
Thereafter, the jigs 12 and 12 are removed from the work table 3 and are gripped by the work indexing means 4 and the work pressing means 5 by the operation switch, and are not in contact with the work table 3. One surface is cut with the processing tool 1. In this case, the working tool 1 is less worn compared to the case where it is fixed on the work table 3 and processed.
[0020]
When the cutting to this surface is finished, the workpiece indexing means 4 indexes the workpiece indexing shaft 7 to a predetermined angle by programmed numerical control, and then applies the machining tool 1 to other surfaces. In the same manner, the workpiece can be cut by rotating the workpiece 2 at a predetermined angle. Note that both sides of the workpiece 2 are held between the first and second positioning holders 8 and 10, but since the contact surface with the workpiece 2 is very small, both sides of the workpiece 2 are also processed. It can be processed into all six surfaces of the workpiece 2 having a prismatic shape.
[0021]
In addition, although the cross-sectional shape of the horizontal fitting groove 15 and the vertical fitting groove 16 of the workpiece 2 is a trapezoidal shape, it is tapered so that one of the opposing surfaces approaches the other as it goes deeper. At the same time, the other surface is formed so as to be perpendicular to the side surface of the workpiece 2, the opening area in front is widened, the opening area is narrowed toward the back, and similarly, the first and second positioning holders 8 are formed. The 10 horizontal protrusions 20 and the vertical protrusions 21 also have a trapezoidal cross section, and a trapezoidal hypotenuse is formed in accordance with the cross-sectional shapes of the horizontal fitting groove 15 and the vertical fitting groove 16 of the workpiece 2. One surface may be a surface perpendicular to the side surfaces of the first and second positioning holders 8 and 10, and the other surface may be an inclined surface.
[0022]
Next, a second embodiment will be described as shown in FIGS. In this embodiment, the work holding means 5 presses and holds the work 2 on the work indexing means 4 using the jigs 11 and 11 as described above without forming a fitting groove on the work 2. In this case, the first and second positioning holders 8 and 10 are formed with a plurality of conical biting portions 25 that bite into the side surface of the workpiece 2 and concave portions 26 around the biting portions 25.
[0023]
That is, the biting portion 25 has a triangular cross section, and the top portion protrudes from the side surfaces of the first and second positioning holders 8 and 10 so as to protrude. A recess 26 is formed around the periphery. Further, a plurality of the biting portions 25 and the concave portions 26 are formed at predetermined intervals.
[0024]
As a result of this formation, when the work pressing means 5 presses and holds the work 2 on the work indexing means 4, the state shown in the center from the state shown on the left side in FIG. Until the side surfaces of the first and second positioning holders 8 and 10 come into contact with the side surface of the work 2, the biting portion 25 bites into the side surface of the work 2 and even if a raised portion 27 occurs due to this biting, the concave portion 26 It is possible to escape and absorb this raised portion 27.
[0025]
In addition, as shown in FIG. 11, before the workpiece pressing means 5 completely presses and holds the workpiece 2 on the workpiece indexing means 4, the first and second positioning holders 8 and 10 hold the workpiece 2 from above and below. Although this may be lightly pressed, this embodiment will be described in detail below. A support portion 30 is formed at the lower front surface of the first and second positioning holders 8 and 10, the biting portion 25 and the concave portion 26 are formed at the front surface, and a bolt 31 is tightened to the upper front end partly cut away. By pressing the work 2 supported by the support part 30 with the pressing piece 32 from above, the work indexing means 4 is prevented from being displaced when the work pressing means 5 completely presses and holds the work 2. .
[0026]
As described above, when the work holding means 5 presses and holds the work 2 in a state in which the support 30 and the pressing piece 32 are not displaced in the vertical direction, the work holding means 5 presses and holds the work 2 in the vertical direction. As described above, the biting portion 25 bites into the side surface of the workpiece 2 until the side surfaces of the first and second positioning holders 8 and 10 come into contact with the side surface of the workpiece 2 with a pressing force much larger than the pressing force. .
[0027]
This embodiment can be applied not only to the second embodiment but also to the first embodiment. Further, the pressure for pressing and gripping is adjusted according to the weight of the workpiece 2, but the lateral projection 20 and the longitudinal projection 21 of the first and second positioning holders 8, 10 are laterally fitted to the workpiece 2. The workpiece 2 is pressed and gripped by fitting into the mating groove 15 and the vertical fitting groove 16, or the biting portion 25 of the first and second positioning holders 8 and 10 bites into the surface of the workpiece 2. According to the embodiment that presses and grips, the pressing force is less than that in the form in which the fitting and the biting are not performed, so that even the pressing ability of the hydraulic cylinder 9 is small.
[0028]
