以下、この考案の実施の形態について添付図面に基づいて説明する。
まず、図１に示すように、ワイヤ放電加工用治具１００は、鉛直方向に起立する支持部１０と、支持部１０の上に固定される被加工物把持部２０と、支持部１０の下部に固定される基台部３０とを備える。
ここで、基台部３０は角度調整部を構成する。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, as illustrated in FIG. 1, a wire electric discharge machining jig 100 includes a support portion 10 that stands in a vertical direction, a workpiece gripping portion 20 that is fixed on the support portion 10, and a lower portion of the support portion 10. And a base 30 fixed to the base.
Here, the base part 30 comprises an angle adjustment part.

図１において、支持部１０は、一対の略円柱形状の第一支柱１１と、各々の第一支柱１１の上に連結され、第一支柱１１よりも長い略円柱形状の第一連結部材１２と、各々の第一支柱１１の底面に取り付けられる略三角形状の板状の支柱台９とを有する。ここで、支持部１０は、例えば図２に示すように、支柱台９に第一支柱１１よりも長い第二支柱１３を取付け、その上に、第一連結部材１２と、第一連結部材１２よりも短い第二連結部材１４と、第二連結部材１４よりも短い第三連結部材１５を連結させた構成にすることもできる。すなわち、支持部１０は、支柱台９の上に設けられる第一支柱１１や第二支柱１３等の各種の支柱に、複数種類の長さの連結部材が着脱可能に連結されて構成される。
なお、支柱台９の上面は、被加工物を載置するための載置面９ａを構成する。
また、以下の説明において、第一支柱１１又は第二支柱１３が延びる方向を方向Ａとする。 In FIG. 1, the support portion 10 includes a pair of substantially columnar first struts 11, a first columnar connecting member 12 that is coupled to the first struts 11 and is longer than the first struts 11. And a substantially triangular plate-like column base 9 attached to the bottom surface of each first column 11. Here, for example, as shown in FIG. 2, the support unit 10 is provided with a second column 13 longer than the first column 11 on the column base 9, and a first coupling member 12 and a first coupling member 12 thereon. The second connecting member 14 shorter than the second connecting member 14 and the third connecting member 15 shorter than the second connecting member 14 may be connected. In other words, the support unit 10 is configured by connecting various types of connecting members detachably to various supporting columns such as the first supporting column 11 and the second supporting column 13 provided on the supporting column 9.
In addition, the upper surface of the column base 9 constitutes a placement surface 9a for placing the workpiece.
In the following description, the direction in which the first column 11 or the second column 13 extends is referred to as direction A.

また、図１又は図２を参照すると、被加工物把持部２０は、一対の第一連結部材１２又は第三連結部材１５の上に架け渡されて固定される支持板２２と、支持板２２に取り付けられ、延長方向に起立して延びる一対の第一保持部調整ネジ２４とを有する。なお、第一保持部調整ネジ２４には第一ナット２４ａが取り付けられている。さらに、第一保持部調整ネジ２４は第二ナット２５を介して支持板２２に回転可能に設けられる。また、第一保持部調整ネジ２４は略直方体形状の保持部２１に接続する。具体的には、保持部２１に形成される第一開口２１ａに、第一開口２１ａよりも径の小さい第一保持部調整ネジ２４が貫通する。なお、保持部２１は第一保持部調整ネジ２４に対して、第一ナット２４ａと第二ナット２５との間に位置するように接続されている。そのため、保持部２１は第一保持部調整ネジ２４が延びる方向Ａに沿って上下に移動することができる。さらに保持部２１には第二開口２１ｂも形成される。なお、第二開口２１ｂにはネジ山が形成されている。そして、第二開口２１ｂには、第一保持部調整ネジ２４と平行に延びる第二保持部調整ネジ２３が挿入され、第二開口２１ｂのネジ山に係合する。そして、第二保持部調整ネジ２３の頭部２３ａは支持板２２に当接し、保持部２１は支持板２２に対して第二保持部調整ネジ２３によって支持される。
ここで、第一保持部調整ネジ２４及び第二保持部調整ネジ２３は、保持部位置調整部を構成する。さらに、保持部２１の第二開口２１ｂ及び第二保持部調整ネジ２３はネジ機構を構成する。 Also, referring to FIG. 1 or FIG. 2, the workpiece gripping portion 20 is supported on a pair of first connecting members 12 or third connecting members 15 and fixed thereon, and a supporting plate 22. And a pair of first holding portion adjusting screws 24 extending upright in the extending direction. A first nut 24 a is attached to the first holding portion adjustment screw 24. Further, the first holding part adjusting screw 24 is rotatably provided on the support plate 22 via the second nut 25. The first holding portion adjusting screw 24 is connected to the holding portion 21 having a substantially rectangular parallelepiped shape. Specifically, the first holding part adjusting screw 24 having a smaller diameter than the first opening 21a passes through the first opening 21a formed in the holding part 21. The holding portion 21 is connected to the first holding portion adjusting screw 24 so as to be positioned between the first nut 24 a and the second nut 25. Therefore, the holding part 21 can move up and down along the direction A in which the first holding part adjusting screw 24 extends. Further, a second opening 21 b is formed in the holding portion 21. A screw thread is formed in the second opening 21b. And the 2nd holding | maintenance part adjustment screw 23 extended in parallel with the 1st holding | maintenance part adjustment screw 24 is inserted in the 2nd opening 21b, and it engages with the thread of the 2nd opening 21b. The head 23 a of the second holding part adjusting screw 23 abuts on the support plate 22, and the holding part 21 is supported by the second holding part adjusting screw 23 with respect to the support plate 22.
Here, the 1st holding | maintenance part adjustment screw 24 and the 2nd holding | maintenance part adjustment screw 23 comprise a holding | maintenance part position adjustment part. Further, the second opening 21b of the holding portion 21 and the second holding portion adjusting screw 23 constitute a screw mechanism.

従って、支持板２２に対する保持部２１の高さを調整する時は、第二保持部調整ネジ２３を保持部２１の第二開口２１ｂに対して回転させ、第二開口２１ｂの下方に突出する第二保持部調整ネジ２３の長さを調整する。これにより、保持部２１は方向Ａに沿って移動し、支持板２２に対する保持部２１の高さが適宜変更される。また、支持板２２に対する保持部２１の高さが決定されると、保持部２１は第二保持部調整ネジ２３によって支持板２２に対して支持される。そして次に、第一保持部調整ネジ２４の第一ナット２４ａが回転させられ、第一ナット２４ａは保持部２１に当接する位置まで低下して、保持部２１に対して上から押さえるように負荷を加える。これにより、図３に示すように、保持部２１は支柱台９の載置面９ａとの間に挟持される被加工物１を上から押さえつけて保持し、位置を固定させる。また、図４の二点鎖線２１’に示すように、保持部２１は第二保持部調整ネジ２３によって支持されつつ、第一保持部調整ネジ２４を支点として水平方向に回転移動可能である。すなわち、保持部２１は、第一保持部調整ネジ２４及び第二保持部調整ネジ２３に取り付けられた状態で、被加工物１の上方側に回転することができる。 Therefore, when adjusting the height of the holding portion 21 with respect to the support plate 22, the second holding portion adjusting screw 23 is rotated with respect to the second opening 21b of the holding portion 21, and the second protrusion 21 protrudes below the second opening 21b. The length of the two holding part adjusting screws 23 is adjusted. Thereby, the holding | maintenance part 21 moves along the direction A, and the height of the holding | maintenance part 21 with respect to the support plate 22 is changed suitably. When the height of the holding portion 21 with respect to the support plate 22 is determined, the holding portion 21 is supported with respect to the support plate 22 by the second holding portion adjusting screw 23. Next, the first nut 24a of the first holding portion adjusting screw 24 is rotated, and the first nut 24a is lowered to a position where it abuts on the holding portion 21 and is loaded so as to press against the holding portion 21 from above. Add Thereby, as shown in FIG. 3, the holding portion 21 presses and holds the workpiece 1 held between the supporting base 9 and the mounting surface 9 a from above to fix the position. Further, as indicated by a two-dot chain line 21 ′ in FIG. 4, the holding portion 21 is supported by the second holding portion adjusting screw 23 and can be rotated and moved in the horizontal direction using the first holding portion adjusting screw 24 as a fulcrum. That is, the holding part 21 can be rotated to the upper side of the workpiece 1 while being attached to the first holding part adjusting screw 24 and the second holding part adjusting screw 23.

さらに、図１〜３、５及び図６を参照すると、基台部３０は、加工機に締結される略直方体の板状のベース板４と、ベース板４の上に載せられて取り付けられ、断面が略Ｌ字形状である角度調整部材３とを有する。角度調整部材３の両側には、一対の略台形形状の板状の張出部３ａが形成されている。さらに、角度調整部材３は、ベース板４に対向するベース取付部３ｂと、ベース取付部３ｂに対してほぼ直角に配置されるとともに支持部１０に接続する支持部取付部３ｃとを有する。また、図１及び図５に示すように、角度調整部材３の支持部取付部３ｃには、支持部１０の一対の第一支柱１１が嵌合し得る３個の溝３３ａ,３３ｂ,３３ｃが形成される。なお、溝３３ａと溝３３ｂとは互いに隣接して設けられており、溝３３ａと溝３３ｂとの間隔は溝３３ｂと溝３３ｃとの間隔よりも短くなるように形成されている。従って、支持部１０の一対の第一支柱１１のうち一方は溝３３ａ又は溝３３ｂのどちらにも嵌り込むことができ、これにより一対の第一支柱１１の間隔を適宜変更することができる。すなわち、図５（Ａ）に示すように、一対の第一支柱１１が溝３３ａと溝３３ｃに嵌合されている時は、ワイヤ放電加工用治具１００は、直径Ｄ１の円柱部材Ｘ１から、円柱部材Ｘ１よりも小さい直径Ｄ２の円柱部材Ｘ２までの大きさの被加工物を保持することができる。一方、図５（Ｂ）に示すように、一対の第一支柱１１が溝３３ｂと溝３３ｃに嵌合されている時は、ワイヤ放電加工用治具１００は、直径Ｄ２の円柱部材Ｘ２から、円柱部材Ｘ２よりも小さい直径Ｄ３の円柱部材Ｘ３までの大きさの被加工物を保持することができる。そして、一対の支柱１１は、溝３３ａ又は溝３３ｂと溝３３ｃとに嵌めこまれた状態で、ボルト６２によって角度調整部材３の支持部取付部３ｃに固定されて取り付けられる。
ここで、角度調整部材３の支持部取付部３ｃの溝３３ａ〜３３ｃは、支持部位置調整機構を構成する。
また、溝３３ａ〜３３ｃには、第一支柱１１のみならず、一対の第二支柱１３も各々嵌合可能である。 Further, referring to FIGS. 1 to 3 and FIG. 6, the base portion 30 is mounted on the base plate 4 and the base plate 4 having a substantially rectangular parallelepiped shape fastened to the processing machine, And an angle adjusting member 3 having a substantially L-shaped cross section. On both sides of the angle adjusting member 3, a pair of substantially trapezoidal plate-like projecting portions 3a are formed. Furthermore, the angle adjusting member 3 includes a base mounting portion 3 b that faces the base plate 4, and a support portion mounting portion 3 c that is disposed substantially at right angles to the base mounting portion 3 b and is connected to the support portion 10. As shown in FIGS. 1 and 5, the support portion mounting portion 3 c of the angle adjusting member 3 has three grooves 33 a, 33 b, 33 c into which the pair of first support columns 11 of the support portion 10 can be fitted. It is formed. The grooves 33a and 33b are provided adjacent to each other, and the distance between the grooves 33a and 33b is shorter than the distance between the grooves 33b and 33c. Therefore, one of the pair of first struts 11 of the support portion 10 can be fitted into either the groove 33a or the groove 33b, whereby the distance between the pair of first struts 11 can be appropriately changed. That is, as shown in FIG. 5A, when the pair of first support columns 11 are fitted in the grooves 33a and 33c, the wire electric discharge machining jig 100 is moved from the columnar member X1 having a diameter D1. A workpiece having a size up to a columnar member X2 having a diameter D2 smaller than that of the columnar member X1 can be held. On the other hand, as shown in FIG. 5B, when the pair of first struts 11 are fitted in the grooves 33b and 33c, the wire electric discharge machining jig 100 is removed from the columnar member X2 having a diameter D2. A workpiece having a size up to a columnar member X3 having a diameter D3 smaller than that of the columnar member X2 can be held. And a pair of support | pillar 11 is fixed and attached to the support part attaching part 3c of the angle adjustment member 3 with the volt | bolt 62 in the state fitted by the groove | channel 33a or the groove | channel 33b, and the groove | channel 33c.
Here, the grooves 33 a to 33 c of the support portion mounting portion 3 c of the angle adjustment member 3 constitute a support portion position adjustment mechanism.
Moreover, not only the 1st support | pillar 11 but a pair of 2nd support | pillar 13 can each be fitted by the groove | channels 33a-33c.

また、角度調整部材３の支持部取付部３ｃの上端面には、図２、３及び図６（Ｂ）に示すように、補強部材５が接続され得る。ここで、補強部材５は、図７に示すように略直方体形状の補強部本体５１と、補強部本体５１に一体的に設けられる細長板形状の突出部５２とを有する。また、補強部本体５１の支持部１０に対向する面には、支持部１０の支柱又は連結部材が嵌合し得る３個の溝５３ａ,５３ｂ,５３ｃが形成される。これらの溝５３ａ,５３ｂ,５３ｃは、角度調整部材３の溝３３ａ,３３ｂ,３３ｃに対応する形状及び位置に形成される。また、補強部本体５１はボルト６９を介して、突出部５２はボルト６３を介して、各々、角度調整部材３に接続されている。 Further, as shown in FIGS. 2, 3, and 6 (B), the reinforcing member 5 can be connected to the upper end surface of the support portion mounting portion 3 c of the angle adjusting member 3. Here, as shown in FIG. 7, the reinforcing member 5 has a substantially rectangular parallelepiped reinforcing portion main body 51 and an elongated plate-like protruding portion 52 provided integrally with the reinforcing portion main body 51. In addition, three grooves 53 a, 53 b, and 53 c into which the support pillars or connecting members of the support portion 10 can be fitted are formed on the surface of the reinforcement portion main body 51 that faces the support portion 10. These grooves 53a, 53b, 53c are formed in shapes and positions corresponding to the grooves 33a, 33b, 33c of the angle adjusting member 3. Further, the reinforcing portion main body 51 is connected to the angle adjusting member 3 via the bolt 69, and the protruding portion 52 is connected to the angle adjusting member 3 via the bolt 63.

さらに、図３及び図４に示すように、角度調整部材３のベース取付部３ｂとベース板４との間には角度調整支点３１が設けられている。角度調整支点３１は、上から見て角度調整部材３のベース取付部３ｂの中央付近に位置する。そして、角度調整部材３は角度調整支点３１を介してベース板４に対して隙間を作って浮くように載せられている（図８参照）。また、角度調整支点３１を中心として、角度調整部材３のベース取付部３ｂとベース板４とを連結する３個のボルト３２が、各々、二等辺三角形の頂点をなすように配置されている。そして、３個のボルト３２を適宜締め付けたり緩めたりすることにより、各々のボルト３２が取り付けられている位置において、角度調整部材３のベース取付部３ｂとベース板４との間の間隔が調整される。これにより、角度調整部材３のベース板４に対する傾斜角度が適宜変化し、角度調整部材３の傾斜角度の変化に伴って支持部１０の傾斜角度も変化する。 Furthermore, as shown in FIGS. 3 and 4, an angle adjustment fulcrum 31 is provided between the base mounting portion 3 b of the angle adjustment member 3 and the base plate 4. The angle adjustment fulcrum 31 is located near the center of the base attachment portion 3b of the angle adjustment member 3 as viewed from above. The angle adjusting member 3 is placed so as to float with respect to the base plate 4 via the angle adjusting fulcrum 31 (see FIG. 8). Further, with the angle adjustment fulcrum 31 as the center, the three bolts 32 that connect the base mounting portion 3b of the angle adjustment member 3 and the base plate 4 are respectively arranged so as to form vertices of an isosceles triangle. And the space | interval between the base attachment part 3b of the angle adjustment member 3 and the base board 4 is adjusted in the position where each bolt 32 is attached by tightening or loosening three bolts 32 suitably. The Thereby, the inclination angle of the angle adjustment member 3 with respect to the base plate 4 is appropriately changed, and the inclination angle of the support portion 10 is also changed with the change of the inclination angle of the angle adjustment member 3.

次に、支持部１０の支柱と連結部材との組み合わせによる保持部２１の高さ調整について、図８（Ａ）〜（Ｄ）を参照して説明する。なお、図８（Ａ）から図８（Ｄ）に至るまで、支持部１０の高さは徐々に高くなり、これに伴い、被加工物把持部２０の保持部２１の位置も高くなる。
まず、図８（Ａ）は、支持部１０が支柱台９と第一支柱１１とによって構成される例である。第一支柱１１の内部には取付孔１１ａが形成されている。そして、取付孔１１ａには第二ナット２５が差し込まれる。第二ナット２５は第一支柱１１の上面との間で支持板２２を挟み込んで固定するとともに、第一保持部調整ネジ２４を支持板２２に対して回転可能となるように支持する。 Next, height adjustment of the holding | maintenance part 21 by the combination of the support | pillar of the support part 10 and a connection member is demonstrated with reference to FIG. 8 (A)-(D). In addition, from FIG. 8 (A) to FIG. 8 (D), the height of the support part 10 becomes high gradually, and the position of the holding | maintenance part 21 of the workpiece holding part 20 also becomes high in connection with this.
First, FIG. 8A is an example in which the support portion 10 is constituted by a support column 9 and a first support column 11. A mounting hole 11 a is formed inside the first support column 11.
