Description

本発明は、例えば、工場内に工程ごとで所定の処理や加工を施される複数の部品を、同じ姿勢または一定の規則的な姿勢で整列させて保持するための複数部品保持治具の製造方法に関する。 The present invention is, for example, the manufacture of a plurality of parts holding jig for aligning and holding a plurality of parts to be subjected to predetermined processing or processing for each process in a factory in the same posture or a fixed regular posture. Regarding the method.

例えば、マグネシウムまたはマグネシウム合金（以下、Ｍｇと略記する）製からなる複数の被処理材を電解槽内に浸漬して陽極酸化処理を施すため、上端にフック部を有する垂直姿勢の支持親柱と、該支持親柱から径方向に沿って放射状に延び且つ平面視がＶ字形状である複数の支持子柱とを備え、前記複数の支持子柱ごとにおける最外端で且つ前記被処理材に接触する一対の部位にＭｇ製の接触部材を個別に配置した陽極酸化処理用治具が提案されている（例えば、特許文献１参照）。
前記陽極酸化処理用治具によれば、前記被処理材を支持子柱ごとの最外端に配置した接触部材に接触させつつ電解液中で確実に保持でき、且つ上記被処理材の全表面に対して陽極酸化処理をムラなく均一に施すことが可能となる。 For example, in order to immerse a plurality of materials to be treated made of magnesium or a magnesium alloy (hereinafter abbreviated as Mg) in an electrolytic cell to perform anodization treatment, a vertical support main column having a hook at the upper end A plurality of support pillars extending radially along the radial direction from the support master pillar and having a V-shaped plan view are provided, and the outermost end of each of the plurality of support pillars and the material to be treated. A jig for anodic oxidation treatment in which Mg contact members are individually arranged at a pair of contacting portions has been proposed (see, for example, Patent Document 1).
According to the anodizing jig, the material to be treated can be reliably held in the electrolytic solution while being in contact with the contact member arranged at the outermost end of each support column, and the entire surface of the material to be treated can be maintained. However, the anodizing treatment can be performed evenly and uniformly.

ところで、前記のような複数の被処理材（部品）を所定の姿勢で保持するための治具は、工程ごとの処理方法や加工方法および被処理材や被加工材の形態（形状、寸法、数量など）によって千差万別とならざるを得ない。そのため、工程ごとの担当者自らによって試行錯誤を繰り返しつつ、自社内で制作するケースが多くみられる。この場合には、制作ロスを招き易く、コスト高となったり、当該工程の処理効率ないし加工効率が向上しにくい、という問題があった。
また、工程ごとの自動化（ＡＩ化、ＩｏＴ化）や、工程間における搬送作業の省力化や無人化などに対応するため、複数の部品を同じ姿勢や一定の規則的な位置ごとに整列させるための治具には、マニピュレータやロボットでも処理可能となる精度の高い部品保持部の制作や、複数の該部品保持部の高配設精度が求められる。しかし、係る要求に対応し得る技術は、これまで提案されていなかった。 By the way, the jig for holding a plurality of materials (parts) to be processed in a predetermined posture as described above includes a processing method and a processing method for each process and a form (shape, dimensions, and shape) of the material to be processed and the material to be processed. There is no choice but to vary depending on the quantity). Therefore, in many cases, the person in charge of each process repeats trial and error to produce the product in-house. In this case, there are problems that production loss is likely to occur, the cost is high, and it is difficult to improve the processing efficiency or processing efficiency of the process.
In addition, in order to support automation (AI, IoT) for each process, labor saving and unmanned transportation work between processes, etc., multiple parts can be aligned in the same posture or at regular regular positions. The jig is required to produce a highly accurate component holding portion that can be processed by a manipulator or a robot, and to have a high disposition accuracy of a plurality of the component holding portions. However, no technology has been proposed so far that can meet such requirements.

The metal wire m shown in FIG. 1 (A) is prepared in advance. The metal wire m is made of, for example, stainless steel, has a diameter of 3 to 6 mm (for example, 4 mm), and has a length necessary for forming the unit holding portion H1 described later.

実際には、前記金属線ｍは、全体が円筒形状に巻き付けられた長尺なコイルであり、該コイルを順次巻き返し、図示しない３次元曲げ加工装置（例えば、ＮＣ式マルチフォーミングマシン）に送られ、該金属線ｍの軸方向に沿って一定速度で搬送するトンネル状のワーク供給部から順次送り出される。更に、該供給部から出た直後に、当該金属線ｍの先端(一端)側から所定の位置ごとに、該金属線ｍの径方向に対し任意の傾斜角度(９０度を含む)で上記金属線ｍを押し曲げ(突き当て)る複数のツールごとにより曲げ加工が順次施された後、後端(他端)側で切断することにより、単位保持部Ｈ１が成形される。 Actually, the metal wire m is a long coil wound in a cylindrical shape as a whole, and the coil is sequentially rewound and sent to a three-dimensional bending machine (for example, an NC type multi-forming machine) (not shown). , The metal wire m is sequentially sent out from a tunnel-shaped work supply unit that is conveyed at a constant speed along the axial direction.

最後に、図１(Ｇ)に示すように、曲げ部ｂ８の他端側に、軸方向に対して緩い傾斜角度の曲げ部ｂ９と、図示で下向きに凸となるようカーブした曲げ部ｂ１０とを順次形成した。その結果、同図および図２(Ａ)に示すように、全体が閉じた変形四角形形状を呈する単位保持部Ｈ１を成形することができた。１つの該単位保持部Ｈ１を成形するために要した時間は、約３０〜４０秒であった。

従って、前記複数部品保持治具２０ａによれば、前記効果(１)〜(４)を得られることが容易に理解される。
尚、複数の単位保持部Ｈ１と、整列補助枠Ｆおよび停止枠Ｓを上面に溶接した前記多孔板６のみとからなる複数部品保持治具であっても、前記効果(１)〜(４)を得ることは可能である。 Moreover, by using the plurality of parts holding jig 20a, as described above, for example, it can contribute to increasing the processing efficiency of the cleaning process.
In particular, when the three-dimensional bending process and the joining process are performed one-stop from the planning and design stages, it is possible to provide even a small lot at a relatively low cost and with a short delivery time.
Therefore, it is easily understood that the effects (1) to (4) can be obtained by the plurality of component holding jigs 20a.
Even in a plurality of component holding jigs composed of only the perforated plate 6 in which the plurality of unit holding portions H1 and the alignment auxiliary frame F and the stop frame S are welded to the upper surface, the effects (1) to (4) It is possible to get.

図４(Ａ)〜(Ｆ)は、前記同様の金属線ｍから前記とは異なる単位保持部Ｈ２を成形する保持部形成工程に関する。
即ち、前記曲げ加工装置を用いて、図４(Ａ)に示す金属線ｍの一端側を直角状に曲げ加工して、図４(Ｂ)に示すように、一端側に曲げ部ｂ１を形成し、該曲げ部ｂ１の他端側を異なる直角方向に沿って曲げ加工して、図４(Ｃ)に示すように、新たな曲げ部ｂ２を形成した。次に、該曲げ部ｂ２の他端側に、直角状の曲げ加工と２つのアール状の曲げ加工とを順次施して、図４(Ｄ)に示すように、直角状の曲げ部ｂ３と、アール形の曲げ部ｂ４，ｂ５とを順次形成した。 4 (A) to 4 (F) relate to a holding portion forming step of molding a unit holding portion H2 different from the above from the same metal wire m.
That is, using the bending apparatus, one end side of the metal wire m shown in FIG. 4A is bent at a right angle to form a bent portion b1 on one end side as shown in FIG. 4B. Then, the other end side of the bent portion b1 was bent along different right-angled directions to form a new bent portion b2 as shown in FIG. 4C. Next, a right-angled bending process and two rounded bending processes are sequentially performed on the other end side of the bending portion b2, and as shown in FIG. 4D, the right-angled bending portion b3 and the right-angled bending portion b3 are subjected to. The rounded bent portions b4 and b5 were sequentially formed.

更に、図４(Ｅ)に示すように、前記曲げ部ｂ４，ｂ５の他端側にこれらと線対称となる曲げ部ｂ６，ｂ７，ｂ８を順次形成した後、曲げ部ｂ８の他端側に全体が台形状となる２つの曲げ部ｂ９，ｂ１０と、前記曲げ部ｂ１，ｂ２と対称になる２つの直角状の曲げ部ｂ１１，ｂ１２とを順次形成した。その結果、図４(Ｆ)に示すように、全体が枠箱形状の単位保持部Ｈ２を成形することができた。１つの該単位保持部Ｈ２を成形するために要した時間は、約３０〜４０秒であった。
尚、以上の各曲げ加工における寸法公差も、±０．５ｍｍ以内である。 Further, as shown in FIG. 4 (E), bent portions b6, b7, and b8 having line symmetry with the bent portions b4 and b5 are sequentially formed on the other end side of the bent portions b4 and b5, and then on the other end side of the bent portion b8. Two bent portions b9 and b10 having a trapezoidal shape as a whole and two right-angled bent portions b11 and b12 symmetrical with the bent portions b1 and b2 were sequentially formed. As a result, as shown in FIG. 4 (F), the unit holding portion H2 having a frame box shape as a whole could be formed. The time required to form one unit holding portion H2 was about 30 to 40 seconds.
The dimensional tolerance in each of the above bending processes is also within ± 0.5 mm.

次いで、複数の前記単位保持部Ｈ２を、図４(Ｇ)中の矢印で例示するように、前記同様の多孔板６の上面に３列に整列させて溶接する接合工程を行う。
この場合、各列ごとに必要な４個または５個の単位保持部Ｈ２を、直線状に並べ、隣接する縦片同士の間を溶接して、予め、当該単位保持部Ｈ２のユニットを３組製作しておき、該ユニットごとを多孔板６の上面に溶接する方法が、これら単位保持部Ｈ２全体の配置精度を高レベルにて安定させる観点上から望ましい。
一方、複数の前記単位保持部Ｈ２を、個別に多孔板６の上面に順次溶接付けして、全体を千鳥状に且つ３列に整列させて溶接する方法を用いても良い。 Next, a joining step is performed in which the plurality of unit holding portions H2 are aligned and welded in three rows on the upper surface of the same perforated plate 6 as illustrated by the arrows in FIG. 4 (G).
In this case, the four or five unit holding portions H2 required for each row are arranged in a straight line, and the adjacent vertical pieces are welded to each other to form three sets of the unit holding portions H2 in advance. A method of manufacturing and welding each unit to the upper surface of the perforated plate 6 is desirable from the viewpoint of stabilizing the arrangement accuracy of the entire unit holding portion H2 at a high level.
On the other hand, a method may be used in which the plurality of unit holding portions H2 are individually welded to the upper surface of the perforated plate 6 in a staggered manner and arranged in three rows.

以上の何れかの接合工程を行うことにより、図４(Ｇ)に例示するように、多孔板６の上面に複数の単位保持部Ｈ２を、直線状且つ千鳥状に３列にして整列されていると共に、これらの周囲を四辺の側枠１３が包囲する複数部品保持治具２０ｂが得られる。
かかる複数部品保持治具２０ｂによれば、図４(Ｈ)に例示するように、単位部品保持部Ｈ２ごとにおいて、全体の外形が円盤形状を呈し、且つ図示で左下隅側に薄肉の円周部を形成する切り欠きｋを有する部品Ｐ２に対して、前記同様に効率良く洗浄処理を施すことが可能となる。
従って、前記複数部品保持治具２０ｂによっても、前記効果(１)〜(４)を得られることが容易に理解される。
但し、前記多孔板６だけと、その上面に複数の前記単位保持部Ｈ２を溶接してなる複数部品保持治具としても、前記効果(１)〜(４)を得ることが可能である。 By performing any of the above joining steps, as illustrated in FIG. 4 (G), a plurality of unit holding portions H2 are arranged in three rows in a straight line and in a staggered manner on the upper surface of the perforated plate 6. At the same time, a plurality of component holding jigs 20b are obtained in which the side frames 13 on all four sides surround them.
According to the plurality of parts holding jig 20b, as illustrated in FIG. 4H, the entire outer shape of each unit part holding portion H2 has a disk shape, and the circumference of a thin wall is shown in the lower left corner side in the drawing. It is possible to efficiently perform the cleaning treatment on the component P2 having the notch k forming the portion in the same manner as described above.
Therefore, it is easily understood that the effects (1) to (4) can be obtained even by the plurality of component holding jigs 20b.
However, the effects (1) to (4) can be obtained even as a plurality of component holding jigs formed by welding only the perforated plate 6 and a plurality of the unit holding portions H2 to the upper surface thereof.

図５(Ａ)〜(Ｄ１)，(Ｄ２)は、更に異なる形態の単位保持部Ｈ３を成形するための単位保持部形成工程を示す。
即ち、前記曲げ加工装置を用いて、図５(Ａ)に示す金属線ｍの一端側を僅かな傾斜の曲げ加工を施して、図５(Ｂ)に示すように、一端側に曲げ部ｂ１を形成し、該曲げ部ｂ１の他端側をやや異なる方向に沿って直角状に曲げ加工して、図５(Ｃ)に示すように、新たな直角状の曲げ部ｂ２を形成した。次に、前記曲げ部ｂ２の他端側を更に若干異なる方向に沿った直角状に曲げ加工し、図５(Ｄ１)，(Ｄ２)の異なる一対の視角で示すように、他端側に新たな直角状の曲げ部ｂ３を形成した。尚、以上の各曲げ加工における寸法公差も、±０．５ｍｍ以内である。 5 (A) to 5 (D1) and 5 (D2) show a unit holding portion forming step for molding a unit holding portion H3 having a different form.
That is, using the bending apparatus, one end side of the metal wire m shown in FIG. 5 (A) is bent with a slight inclination, and as shown in FIG. 5 (B), the bent portion b1 is formed on one end side. Was formed, and the other end side of the bent portion b1 was bent at a right angle along a slightly different direction to form a new right-angled bent portion b2 as shown in FIG. 5C. Next, the other end side of the bent portion b2 is further bent at a right angle along slightly different directions, and as shown by a pair of different viewing angles in FIGS. 5 (D1) and 5 (D2), the other end side is newly bent. A right-angled bent portion b3 was formed. The dimensional tolerance in each of the above bending processes is also within ± 0.5 mm.

更に、図５(Ｄ１)，(Ｄ２)中の矢印で示すように、上下一対の水平片の先端ごとの上方に対し、金属薄板からなり、側面視がＬ字形状である爪片１８の水平片１９を個別に溶接付けした。その結果、全体が側面視でコ字形状を呈し、且つ上下一対の水平片の先端ごとに上記爪片１８を立設させた単位保持部Ｈ３が得られた。１つの該単位保持部Ｈ３を成形する曲げ加工に要した時間は、約６〜１０秒である。
次に、複数の上記単位保持部Ｈ３を、図５(Ｅ)に示すように、全体が円筒形状である支持枠２２の外周側に沿って溶接(接合)する接合工程を行った。
上記支持枠２２は、図示のように、金属線からなる上リング片２３と下リング片２４との間を、平面視で等間隔に配置した８本の柱片２５により接合したものである。尚、下リング片２４の内側には、補強片２６が十字形状にして接合されている。 Further, as shown by the arrows in FIGS. 5 (D1) and 5 (D2), the horizontal of the claw piece 18 which is made of a thin metal plate and has an L-shaped side view with respect to the upper side of each tip of the pair of upper and lower horizontal pieces. The pieces 19 were individually welded. As a result, a unit holding portion H3 was obtained, which had a U-shape as a whole in a side view and in which the claw pieces 18 were erected at the tips of a pair of upper and lower horizontal pieces. The time required for the bending process for forming one unit holding portion H3 is about 6 to 10 seconds.
Next, as shown in FIG. 5 (E), the plurality of unit holding portions H3 were welded (joined) along the outer peripheral side of the support frame 22 having a cylindrical shape as a whole.
As shown in the figure, the support frame 22 is formed by joining the upper ring piece 23 made of a metal wire and the lower ring piece 24 with eight pillar pieces 25 arranged at equal intervals in a plan view. A reinforcing piece 26 is joined to the inside of the lower ring piece 24 in a cross shape.

更に、図５(Ｅ)，(Ｆ)に示すように、前記支持枠２２における８本の柱片２５ごとの外周側と、前記単位保持片Ｈ３ごとの縦片との間を溶接(ｗ)付けして個別に接合することで、複数部品保持治具２１が得られる。
８個の前記単位保持片Ｈ３は、平面視で円環状に整列していると共に、単位保持片Ｈ３ごとおける一対ずつの前記爪片１８は、前記柱片２５ごとから外周側に向かって同じ姿勢によって突出している。
そのため、図５(Ｆ)で例示するように、前記単位保持片Ｈ３ごとにおける上下一対の水平片の先端から立設した上下２つの爪片１８を、側面視が全体で弓形状で且つ水平断面が円弧形状を呈する部品Ｐ３の内側に設けられた上下一対の下向きの鈎部ｐ１，ｐ２における下向きの凹所内に進入させて保持できる。即ち、８個の部品Ｐ３を支持枠２２の外周側(円周方向)に沿って、全て同じ姿勢で整列させた状態で保持することができる。 Further, as shown in FIGS. 5 (E) and 5 (F), welding (w) is performed between the outer peripheral side of each of the eight pillar pieces 25 in the support frame 22 and the vertical piece of each unit holding piece H3. A plurality of component holding jigs 21 can be obtained by attaching and joining them individually.
The eight unit holding pieces H3 are arranged in an annular shape in a plan view, and the pair of claw pieces 18 placed together with the unit holding piece H3 have the same posture from each pillar piece 25 toward the outer peripheral side. Protrudes by.
Therefore, as illustrated in FIG. 5 (F), the two upper and lower claw pieces 18 erected from the tips of the pair of upper and lower horizontal pieces in each unit holding piece H3 have a bow shape as a whole and a horizontal cross section. Can enter and hold in the downward recesses of the pair of vertical hooks p1 and p2 provided inside the component P3 having an arc shape. That is, the eight parts P3 can be held in a state of being aligned in the same posture along the outer peripheral side (circumferential direction) of the support frame 22.

その結果、例えば、前記支持枠２２を回転テーブル(図示せず)上に載置し、且つ一定速度で回転させることにより、外側からＣＣＤカメラによって、８個の前記部品Ｐ３の外側面を順次撮像することで、個々の部品Ｐ３における外側面の性状を、精度良く迅速に検査することが可能となる。あるいは、支持枠２２を上記同様に回転させた状態で、外側から塗料噴霧ノズルにより塗料をスプレー塗装または静電塗装することで、個々の部品Ｐ３における外側面に対し所望の塗装を効率良く施すことも可能となる。尚、上記塗装に替えて種々のブラスト処理を行うようにしても良い。
従って、前記複数部品保持治具２１によっても、前記効果(１)〜(４)を得られることが容易に理解されよう。 As a result, for example, by placing the support frame 22 on a rotary table (not shown) and rotating it at a constant speed, the outer surfaces of the eight parts P3 are sequentially imaged by a CCD camera from the outside. By doing so, it becomes possible to inspect the properties of the outer surface of each component P3 with high accuracy and speed. Alternatively, while the support frame 22 is rotated in the same manner as described above, the paint is spray-coated or electrostatically coated from the outside with a paint spray nozzle to efficiently apply the desired coating to the outer surface of each component P3. Is also possible. In addition, various blasting treatments may be performed instead of the above coating.
Therefore, it can be easily understood that the effects (1) to (4) can be obtained by the plurality of component holding jigs 21.
