Description

工作機械及び加工方法Machine tool and processing method
 本発明は、工作機械に関し、特に、ワーク搬送機構によりワークを搬送し、加工ヘッドによりワークを加工施す改良された工作機械に関する。 The present invention relates to a machine tool, and more particularly, to an improved machine tool that conveys a workpiece by a workpiece conveyance mechanism and processes the workpiece by a machining head.
 ギャングヘッドと呼ばれる加工ヘッドにより、ワークに機械加工を施す工作機械が、例えば、特許文献に開示されているように知られている。 2. Description of the Related Art A machine tool that performs machining on a workpiece by a machining head called a gang head is known as disclosed in, for example, patent literature.
 特許文献1に開示されているように、加工ユニットは、6個の多軸加工ヘッドを備え、クランプユニットに向けて接離するよう水平方向に移動する。クランプユニットは、搬送ラインに設けられている。クランプユニットは、搬送ラインに沿って水平方向に直交する水平方向に搬送される。クランプユニットは、進退アームを備え、これらの進退アームでワークが挟持される。 As disclosed in Patent Document 1, the machining unit includes six multi-axis machining heads and moves in a horizontal direction so as to approach and separate from the clamp unit. The clamp unit is provided in the transport line. The clamp unit is transported in the horizontal direction perpendicular to the horizontal direction along the transport line. The clamp unit includes an advance / retreat arm, and a workpiece is clamped by these advance / retreat arms.
 特許文献1に開示されている加工装置の構造では、重量物である加工ユニットを、搬送ラインに対して接離方向に移動するため、移動に費やすエネルギーが嵩む。また、クランプユニットは、搬送ラインで搬送され、所定位置で止められ、その位置で加工ユニットにより、機械加工が施されるが、クランプユニットの停止位置は正確である必要がある。正確にするには搬送速度を下げることや、停止位置でノックピンを打ち込むことなどの配慮が必要となる。その結果、搬送ラインの構造が複雑化すると共に搬送速度を上げることが困難になる。 In the structure of the processing apparatus disclosed in Patent Document 1, the processing unit that is a heavy object is moved in the contact / separation direction with respect to the transfer line, and thus energy consumed for movement increases. Further, the clamp unit is transported by a transport line, stopped at a predetermined position, and machined by the processing unit at that position. However, the stop position of the clamp unit needs to be accurate. To be accurate, considerations such as lowering the transport speed and driving a knock pin at the stop position are required. As a result, the structure of the transport line becomes complicated and it is difficult to increase the transport speed.
 省エネルギーの観点から加工ユニットは静止させることが望まれ、生産性向上の観点から搬送ラインの高速化が求められる。すなわち、加工ユニットは移動させる必要が無く、搬送ラインを高速にすることができる工作機械が望まれる。 From the viewpoint of energy saving, it is desirable to keep the processing unit stationary, and from the viewpoint of improving productivity, it is required to increase the speed of the transfer line. That is, there is a need for a machine tool that does not need to move the processing unit and that can speed up the transfer line.

The drive gear 23 is rotated by a spindle motor 26, whereby the driven gears 24 and 25 are rotated. 18 and 19 are rotated at high speed. Since the processing head 13 includes a plurality of spindle shafts 18 and 19 densely, it is also called a gang head.
 加工ヘッド13からガイドバー27、27が下方に向けて延び、これらのガイドバー27、27に沿って上下動可能にワーク抑えプレート16が案内される。ワーク抑えプレート16は、加工ヘッド13の下面から延びるクッションユニット28、28により吊される。 The guide bars 27 and 27 extend downward from the processing head 13, and the workpiece holding plate 16 is guided along the guide bars 27 and 27 so as to be movable up and down.

 次に、本発明の工作機械10へ加工前のワークを供給し、工作機械10から加工済みワークを受け取る役割を果たすワーク搬送機構について、図5に基づいて説明する。
 図5に示すように、ワーク搬送機構40は、逆U字状フレーム12の下部を水平に横断する水平移動部材41と、この水平移動部材41に所定ピッチで立てられたアーム42と、このアーム42の上部に取付けられワークW1、W2を搬送する搬送治具50とからなる。搬送治具50は、支持バー43と、この支持バー43から上に延ばされる大小の第1の受けピン44及び第2の受けピン45とからなる。
Next, a workpiece transfer mechanism that serves to supply a workpiece before machining to the machine tool 10 of the present invention and receive a machined workpiece from the machine tool 10 will be described with reference to FIG.
As shown in FIG. 5, the work transport mechanism 40 includes a horizontal moving member 41 that horizontally traverses the lower portion of the inverted U-shaped frame 12, an arm 42 that stands on the horizontal moving member 41 at a predetermined pitch, 42, and a conveying jig 50 that conveys the workpieces W1, W2. The conveyance jig 50 includes a support bar 43 and first and second receiving pins 44 and 45 that are extended from the support bar 43.
 すなわち、ワーク搬送機構40は、加工前のワークW1及び加工済みワークW2を水平方向に搬送する機構であり、上下へ移動することはない。搬送治具50は水平に移動するだけであり、支持バー43と、大小の第1の受けピン44及び第2の受けピン45とからなる簡単なものである。なお、本実施例におけるワークW1、W2は、無段変速機用ケース又はこのケースの開口を塞ぐリッドであるが、ワークW1の形態、種類、用途は任意である。 That is, the workpiece conveyance mechanism 40 is a mechanism that conveys the workpiece W1 and the workpiece W2 before machining in the horizontal direction, and does not move up and down. The conveying jig 50 simply moves horizontally, and is a simple one composed of a support bar 43, large and small first receiving pins 44, and second receiving pins 45. The workpieces W1 and W2 in this embodiment are a continuously variable transmission case or a lid that closes the opening of the case, but the form, type, and use of the workpiece W1 are arbitrary.
 図6に示すように、アーム42はC型アームである。そして、ワーク受けプレート15に、T字形を呈する貫通溝47を設ける。この貫通溝47は、相対的に支持バー43とアーム42の通過を許容する溝である。支持バー43とアーム42は、上下に移動しない。すなわち、搬送治具50は、上下に移動せず、横に移動するだけである。実線で示すワーク受けプレート15を下げると、貫通溝47が支持バー43とアーム42に干渉することなく、想像線の位置に至る。すなわち、ワーク受けプレート15は、実線の位置から想像線の位置まで、上下に移動可能となる。 As shown in FIG. 6, the arm 42 is a C-type arm. The workpiece receiving plate 15 is provided with a through groove 47 having a T-shape. The through groove 47 is a groove that relatively allows the support bar 43 and the arm 42 to pass therethrough. The support bar 43 and the arm 42 do not move up and down. That is, the conveyance jig 50 does not move up and down, but only moves sideways. When the workpiece receiving plate 15 indicated by the solid line is lowered, the through groove 47 reaches the position of the imaginary line without interfering with the support bar 43 and the arm 42. That is, the workpiece receiving plate 15 can move up and down from the position of the solid line to the position of the imaginary line.
 なお、ワーク受けプレート15には、第1受け面48と、第1の位置決めピン49と、第2受け面51と、第2の位置決めピン52とが、設けられている。 The work receiving plate 15 is provided with a first receiving surface 48, a first positioning pin 49, a second receiving surface 51, and a second positioning pin 52.
 図7に示すように、ワークW1、W2の下部に、第1の位置決めピン49が嵌合する第1の位置決めピン穴64と、第2の位置決めピン52が嵌合する第2の位置決めピン穴65とが設けられる。ワーク受けプレート15が上昇することで、第1の位置決めピン穴64へ第1の位置決めピン49が嵌合し、嵌合する第2の位置決めピン穴65に第2の位置決めピン52が嵌合する。 As shown in FIG. 7, a first positioning pin hole 64 into which the first positioning pin 49 fits and a second positioning pin hole into which the second positioning pin 52 fits below the workpieces W1 and W2. 65 is provided. When the workpiece receiving plate 15 is raised, the first positioning pin 49 is fitted into the first positioning pin hole 64, and the second positioning pin 52 is fitted into the second positioning pin hole 65 to be fitted. .
 また、ワークW1、W2の下部に、第1の受けピン44が嵌合する第1の係合穴66と、第2の受けピン45が嵌合する第2の係合穴67とが設けられる。なお、ワークW1、W2の形状は、図7に示した形状に限定されず、クランクケースやシリンダヘッドの他、一般的な機械部品であれば他の形状であっても差し支えない。また、位置決めピン穴64、65及び係合穴66、67の大きさや位置に合わせて、位置決めピン49、52及び受けピン44、45の大きさ、長さ、位置及び個数が適宜決められる。 In addition, a first engagement hole 66 into which the first receiving pin 44 is fitted and a second engagement hole 67 into which the second receiving pin 45 is fitted are provided below the workpieces W1 and W2. . The shapes of the workpieces W1 and W2 are not limited to the shapes shown in FIG. 7, and other shapes may be used as long as they are general mechanical parts other than the crankcase and the cylinder head. Further, the size, length, position, and number of the positioning pins 49, 52 and the receiving pins 44, 45 are appropriately determined according to the size and position of the positioning pin holes 64, 65 and the engagement holes 66, 67.
 以上の構成からなる工作機械の作用を、図8及び図9に基づいて説明する。
 図8(a)に示すように、ワーク受けプレート15はワークW1の下方に保持されている。図6で説明したように、アーム42がワーク受けプレート15を迂回するようにC型を呈しているため、アーム42がワーク受けプレート15に干渉することなく、加工前のワークW1は、ワーク搬送機構40により、水平に搬送される。ワークW1は、ワーク投入口から又は前工程から加工ヘッド13下方まで搬送され、所定位置で停められる。(搬送工程)
The operation of the machine tool having the above configuration will be described with reference to FIGS.
As shown in FIG. 8A, the workpiece receiving plate 15 is held below the workpiece W1. As described with reference to FIG. 6, since the arm 42 has a C shape so as to bypass the workpiece receiving plate 15, the arm 42 does not interfere with the workpiece receiving plate 15, and the workpiece W <b> 1 before processing can be conveyed. It is conveyed horizontally by the mechanism 40. The workpiece W1 is conveyed from the workpiece insertion port or from the previous process to the lower part of the machining head 13 and stopped at a predetermined position. (Conveying process)
 図8(b)に示すように、ワーク受けプレート15を上げることにより、ワークW1はワーク受けプレート15で掬い上げられる。ワークW1は、第1の受けピン44及び第2の受けピン45から離れるが、第1の位置決めピン49と第2の位置決めピン52とで水平方向の位置決めがなされ、第1受け面48と第2受け面51とで鉛直方向の位置決めがなされる。図ではワーク受けプレート15は上昇の途中であって、ワークW1とワーク抑えプレート16との間には隙間がある。すなわち、ワークW1を、搬送治具50からワーク受けプレート15へ移載する(加工前移載工程)。 As shown in FIG. 8 (b), the workpiece W 1 is scooped up by the workpiece receiving plate 15 by raising the workpiece receiving plate 15. The workpiece W1 is separated from the first receiving pin 44 and the second receiving pin 45, but is positioned in the horizontal direction by the first positioning pin 49 and the second positioning pin 52, and the first receiving surface 48 and the first receiving pin 48 are 2 Vertical positioning is performed with the receiving surface 51. In the figure, the workpiece receiving plate 15 is in the middle of rising, and there is a gap between the workpiece W1 and the workpiece holding plate 16. In other words, the workpiece W1 is transferred from the conveying jig 50 to the workpiece receiving plate 15 (pre-processing transfer step).
 ワーク受けプレート15を更に上昇させると、図9(a)に示すように、ワークW1の上面がワーク抑えプレート16に当接する。更に、ワーク受けプレート15を上昇させると、クッションユニット28、28が縮み、この縮み量に応じてクッションユニット28、28はワークW1をワーク受けプレート15へ付勢する。すなわち、ワークW1を、ワーク受けプレート15とワーク抑えプレート16とで挟みクランプする(ワーククランプ工程)。 When the workpiece receiving plate 15 is further raised, the upper surface of the workpiece W1 comes into contact with the workpiece holding plate 16 as shown in FIG. When the workpiece receiving plate 15 is further raised, the cushion units 28 and 28 are contracted, and the cushion units 28 and 28 urge the workpiece W1 toward the workpiece receiving plate 15 in accordance with the contraction amount. That is, the workpiece W1 is clamped between the workpiece receiving plate 15 and the workpiece holding plate 16 (work clamping process).
 図9(b)に示すように、ワーク受けプレート15とワーク抑えプレート16で挟持されたワークW1に、加工ヘッド13の切削工具21、22により機械加工を施す(加工工程)。 As shown in FIG. 9B, the workpiece W1 sandwiched between the workpiece receiving plate 15 and the workpiece holding plate 16 is machined by the cutting tools 21 and 22 of the machining head 13 (machining process).
 機械加工を終えたら、図9(a)→図8(b)→図8(a)の順で、ワーク受けプレート15を下げ、加工済みワークW2を支持バー43へ受け渡す。ワークW2の係合穴66、67に、それぞれ受けピン44、45が嵌合される。すなわち、ワークW2を、ワーク受けプレート15から搬送治具50に移載する(加工後移載工程)。 After finishing the machining, the workpiece receiving plate 15 is lowered in the order of FIG. 9A → FIG. 8B → FIG. 8A, and the processed workpiece W2 is transferred to the support bar 43. The receiving pins 44 and 45 are fitted into the engaging holes 66 and 67 of the workpiece W2, respectively. That is, the workpiece W2 is transferred from the workpiece receiving plate 15 to the conveying jig 50 (post-processing transfer step).
 以上の説明から明らかなように、加工ヘッド13は静止させ、ワークW1を加工ヘッド13へ接近させる。重量物である加工ヘッド13を移動させないため、省エネルギーが図れる。 As is clear from the above description, the machining head 13 is stopped and the workpiece W1 is moved closer to the machining head 13. Since the heavy processing head 13 is not moved, energy saving can be achieved.
 また、加工ヘッド13にワーク受けプレート移動機構14(図3)を付設し、このワーク受けプレート移動機構14でワーク受けプレート15を加工ヘッド13へ接近させる。ワーク受けプレート15とワーク抑えプレート16でワークW1を挟持しながら、ワークW1を加工ヘッド13へ接近させる。すなわち、ワーク搬送機構40からワークW1を分離して、加工ヘッド13へ接近させるため、ワークW1に影響されることなく、ワーク搬送機構40の搬送速度を高めることができる。 Also, a workpiece receiving plate moving mechanism 14 (FIG. 3) is attached to the machining head 13, and the workpiece receiving plate 15 is brought close to the machining head 13 by the workpiece receiving plate moving mechanism 14. The workpiece W1 is moved closer to the machining head 13 while the workpiece W1 is held between the workpiece receiving plate 15 and the workpiece holding plate 16. That is, since the workpiece W1 is separated from the workpiece conveyance mechanism 40 and brought close to the machining head 13, the conveyance speed of the workpiece conveyance mechanism 40 can be increased without being affected by the workpiece W1.
 次に、好ましい変形例を説明する。
 図10に示すように、ワーク受けプレート15に位置決めノックピン54(以下、ノックピン54と記す。)が設けられ、ワーク抑えプレート16に柱状部材55が設けられ、この柱状部材55にノック穴56が設けられる。加えて、ノックピン54に側方へ開口する溝57を形成し、柱状部材55の近傍にてワーク抑えプレート16にクランプ機構58を設ける。
Next, a preferred modification will be described.
As shown in FIG. 10, a positioning knock pin 54 (hereinafter referred to as a knock pin 54) is provided on the workpiece receiving plate 15, a columnar member 55 is provided on the workpiece holding plate 16, and a knock hole 56 is provided in the columnar member 55. It is done. In addition, a groove 57 that opens laterally is formed in the knock pin 54, and a clamp mechanism 58 is provided in the workpiece restraining plate 16 in the vicinity of the columnar member 55.
 クランプ機構58は、斜め溝と軸方向溝を連続させてなるカム溝59が内蔵された油圧シリンダが好適である。この油圧シリンダ58を縮動させると、斜め溝によりピストンロッド29が回転する。次に、軸方向溝によりピストンロッド29は、回転しないで軸方向へ移動する。この油圧シリンダ58は、旋回と直線移動とを連続して実施するシリンダユニットである。 The clamping mechanism 58 is preferably a hydraulic cylinder with a built-in cam groove 59 formed by connecting an oblique groove and an axial groove. When the hydraulic cylinder 58 is contracted, the piston rod 29 is rotated by the oblique groove. Next, the piston rod 29 moves in the axial direction without rotating due to the axial groove. The hydraulic cylinder 58 is a cylinder unit that continuously performs turning and linear movement.
 先ず、ピストンロッド29により、ワーク受けプレート15を上昇させる。すると、ノック穴56へノックピン54が嵌合する。
 図11に示すように、クランプ機構58を作動させる。すると、クランプ爪61が矢印(1)のように90°程度旋回した後、矢印(2)のように移動して、ノックピン54を柱状部材55へ引きつける。結果、ワーク受けプレート15にワーク抑えプレート16がクランプされる。
First, the workpiece receiving plate 15 is raised by the piston rod 29. Then, the knock pin 54 is fitted into the knock hole 56.
As shown in FIG. 11, the clamp mechanism 58 is operated. Then, after the clamping claw 61 turns about 90 ° as indicated by the arrow (1), it moves as indicated by the arrow (2), and the knock pin 54 is attracted to the columnar member 55. As a result, the workpiece holding plate 16 is clamped to the workpiece receiving plate 15.
 すなわち、ノックピン54とノック穴56とにより、ワーク受けプレート15にワーク抑えプレート16が位置決めされる。ワーク受けプレート15にワーク抑えプレート16が位置決めされるため、挟持されるワークの位置が正確に定まる。 That is, the workpiece holding plate 16 is positioned on the workpiece receiving plate 15 by the knock pin 54 and the knock hole 56. Since the workpiece holding plate 16 is positioned on the workpiece receiving plate 15, the position of the workpiece to be clamped is accurately determined.
 図9において、加工ヘッド13による機械加工の際に、ワークW1に切削抵抗に相当する力が加わる。クランプ機構が無いときには、ワーク抑えプレート16で強くワークW1を押す必要があるため、ワーク抑えプレートに付属する弾性部材(クッションユニット28、28)を強化する必要がある。 In FIG. 9, a force corresponding to the cutting force is applied to the workpiece W1 during machining by the machining head 13. When there is no clamping mechanism, it is necessary to strongly press the workpiece W1 with the workpiece holding plate 16, and therefore it is necessary to strengthen the elastic members (cushion units 28, 28) attached to the workpiece holding plate.
 この点、図11の構造であれば、クランプ機構58、58を備えることにより、ワーク抑えプレート16に付属する弾性部材28(図2)は弱くて済み、弾性部材の軽量、小型化が図れる。なお、天地を逆にして、ワーク受けプレート15に柱状部材55を設け、ワーク抑えプレート16にノックピン54を設けてもよい。 In this regard, with the structure of FIG. 11, by providing the clamp mechanisms 58, 58, the elastic member 28 (FIG. 2) attached to the work holding plate 16 can be weak, and the elastic member can be reduced in weight and size. Note that the columnar member 55 may be provided on the workpiece receiving plate 15 and the knock pin 54 may be provided on the workpiece holding plate 16 with the top and bottom reversed.
 また、図12に示すように、加工ヘッド13(図1)は複数設けてもよく、複数の加工ヘッド13の数に応じて、搬送治具50、50を複数個設けてもよい。複数の搬送治具50、50は互いに連結される。複数のワーク受けプレート15、15を一体的にし、1個のワーク受けプレート15に2個のワークW1、W1を載せるようにしてもよい。複数のワーク受けプレート15、15を一体的にすることで、1個のワーク受けプレート移動機構14により複数のワーク受けプレート15、15を同時に昇降させてもよい。 Further, as shown in FIG. 12, a plurality of processing heads 13 (FIG. 1) may be provided, and a plurality of conveying jigs 50, 50 may be provided according to the number of the plurality of processing heads 13. The plurality of conveying jigs 50 and 50 are connected to each other. A plurality of workpiece receiving plates 15, 15 may be integrated, and two workpieces W 1, W 1 may be placed on one workpiece receiving plate 15. By integrating the plurality of workpiece receiving plates 15 and 15, the plurality of workpiece receiving plates 15 and 15 may be moved up and down simultaneously by one workpiece receiving plate moving mechanism 14.
 この場合、図13に示すように、2個のワークW1、W1の重心と、1個のワーク受けプレート15の重心とを統合した総合的重心点にピストンロッド29の中心を合致させることができる。釣り合いが取れているために、1本のピストンロッド29だけで、ワーク受けプレート15を昇降させることができる。 In this case, as shown in FIG. 13, the center of the piston rod 29 can be made to coincide with the total center of gravity obtained by integrating the center of gravity of the two workpieces W1 and W1 and the center of gravity of one workpiece receiving plate 15. . Since the balance is achieved, the workpiece receiving plate 15 can be raised and lowered with only one piston rod 29.
 なお、理想的には、総合的重心点にピストンロッド29の中心を合致させるが、ピストンロッド29の中心は、ピストンロッド29の外径寸法程度は総合的重心点からオフセットすることが許容される。小さな不均衡であればガイドポスト32、32で許容されるからである。 Ideally, the center of the piston rod 29 is made to coincide with the center of gravity of the piston rod 29. However, the center of the piston rod 29 is allowed to be offset from the center of gravity of the piston rod 29 by the outer diameter dimension. . This is because a small imbalance is allowed by the guide posts 32 and 32.
 結果、図3に示すように、ワーク受けプレート移動機構14は、1個の流体圧シリンダユニットで済ませることができる。1個の流体圧シリンダユニットであれば、装置が簡単になる設備コストを低減することが可能となる。 As a result, as shown in FIG. 3, the workpiece receiving plate moving mechanism 14 can be completed with one fluid pressure cylinder unit. If one fluid pressure cylinder unit is used, it is possible to reduce the equipment cost for simplifying the apparatus.
 なお、ワーク受けプレート移動機構14は、複数個(複数本)の流体圧シリンダユニットで構成することもできる。すなわち、図14(a)に示すように、2本のピストンロッド29、29でワーク受けプレート15を昇降させるようにしてもよい。この場合、複数本のピストンロッド29、29を1本に集約してなる仮想的中心軸63を定める。具体的には、ピストンロッド29、29同士を結んだ線62の中点が仮想的中心軸63となる。 Note that the workpiece receiving plate moving mechanism 14 can also be composed of a plurality (a plurality) of fluid pressure cylinder units. That is, as shown in FIG. 14A, the workpiece receiving plate 15 may be moved up and down by two piston rods 29 and 29. In this case, a virtual central axis 63 formed by integrating a plurality of piston rods 29, 29 into one is defined. Specifically, the midpoint of the line 62 connecting the piston rods 29, 29 becomes the virtual central axis 63.
 この仮想的中心軸63が総合的重心点に合致する若しくは略合致するように、2本のピストンロッド29、29を位置決めする。ピストンロッド29、29に曲げが掛かりにくくなる。結果、ピストンロッド29、29を大径にする必要が無く、小径化が可能となり、ワーク受けプレート移動機構14の小型、軽量化が図れる。 The two piston rods 29 and 29 are positioned so that the virtual center axis 63 matches or substantially matches the total center of gravity. The piston rods 29 and 29 are less likely to be bent. As a result, there is no need to increase the diameter of the piston rods 29 and 29, the diameter can be reduced, and the work receiving plate moving mechanism 14 can be reduced in size and weight.
 また、図14(b)に3本のピストンロッド29、29、29でワーク受けプレート15を昇降させるようにしてもよい。この場合、中央のピストンロッド29が仮想的中心軸63となる。この仮想的中心軸63が総合的重心点に合致する若しくは略合致するように、3本のピストンロッド29、29、29を位置決めする。ピストンロッド29、29、29に曲げが掛かりにくくなる。結果、ピストンロッド29、29、29を大径にする必要が無く、小径化が可能となり、ワーク受けプレート移動機構14の小型、軽量化が図れる。 14B, the workpiece receiving plate 15 may be moved up and down by three piston rods 29, 29 and 29. As shown in FIG. In this case, the central piston rod 29 becomes the virtual central axis 63. The three piston rods 29, 29, 29 are positioned so that the virtual center axis 63 matches or substantially matches the total center of gravity. The piston rods 29, 29, 29 are less likely to be bent. As a result, there is no need to increase the diameter of the piston rods 29, 29, 29, the diameter can be reduced, and the work receiving plate moving mechanism 14 can be reduced in size and weight.
 なお、図10及び図11で説明したクランプ機構58は、安価なロータリアクチュエータと安価なシリンダとを単純に組み合わせることもでき、実施例の構造に限定されるものではない。 The clamp mechanism 58 described in FIGS. 10 and 11 can be simply combined with an inexpensive rotary actuator and an inexpensive cylinder, and is not limited to the structure of the embodiment.
