そこで、前記第１孔６ａが、第１および第２リング６０５、６０６の内側を通るようにして、第１補助部材６０２から本体６０１に渡って形成される。この第１孔６ａは、第１補助部材６０２部分が貫通形成されることで上方に開口し、下方が第２補助部材６０３によって塞がれている。ここで、この第１孔６ａの、上方に開口する口元部分には、掛止溝６ｈが設けられている。そして、この第１孔６ａの口元部分を通って、連結部材３が第１部材７の挿入孔７ａに挿入されて、ワーク２の下面２ｂが受面６ｅに当接したときには、連結部材３に設けられた被掛止部材３ｄが、前記掛止溝６ｈに掛止められ、連結部材３は、挿入孔７ａ内に軽く保持される。 Therefore, the first hole 6 a is formed from the first auxiliary member 602 to the main body 601 so as to pass inside the first and second rings 605 and 606. The first hole 6a is opened upward by forming the first auxiliary member 602 part therethrough, and the lower part is closed by the second auxiliary member 603.

And this 2nd hole 6b is opened to the side by the 3rd auxiliary member 604 part penetratingly forming, and is connecting with the 1st hole 6a inside the main body 601 used as the other side. In the illustrated embodiment, the first direction 11 in which the first hole 6a extends and the second direction 12 in which the second hole 6b extends are orthogonal to each other. A packing 30 is provided at the mouth of the second hole 6b to seal between the second member 8 and the second hole 6b.

また、固定具本体６には、第１位置決め部６ｉと第２位置決め部６ｊとが設けられている。詳細には、第１位置決め部６ｉは、第２補助部材６０３に下方に突出するようにして設けられ、第２位置決め部６ｊは、本体６０１の下面に固定された位置決めピン６ｋによって形成される。そして、これら第１位置決め部６ｉと第２位置決め部６ｊとが、それぞれ、取付具ベース１における、第１位置決め孔１ａと第２位置決め孔１ｂとに嵌まることで、この固定具本体６、ひいては固定具４は、取付具ベース１に対して位置決めされる。また、固定具本体６は、フランジ部６ｍ、６ｍを有しており、このフランジ部６ｍには、取付孔６ｎが設けられている。そして、この固定具本体６、ひいては固定具４は、取付孔６ｎに挿入されて取付具ベース１にねじ込まれる、ボルト等の固着部材１９によって、その取付具ベース１に着脱可能に取付固定される。 Further, the fixture main body 6 is provided with a first positioning portion 6i and a second positioning portion 6j. Specifically, the first positioning portion 6 i is provided on the second auxiliary member 603 so as to protrude downward, and the second positioning portion 6 j is formed by positioning pins 6 k fixed to the lower surface of the main body 601. And these 1st positioning part 6i and the 2nd positioning part 6j are fitted in the 1st positioning hole 1a and the 2nd positioning hole 1b in the fixture base 1, respectively, This fixture main body 6 and by extension The fixture 4 is positioned with respect to the fixture base 1.

And this fixing tool main body 6 and by extension, the fixing tool 4 are detachably attached and fixed to the fixing tool base 1 by fixing members 19 such as bolts which are inserted into the mounting holes 6n and screwed into the fixing tool base 1. .

第１部材７は、第１方向１１に延びて内側の孔が前記挿入孔７ａとなる筒体７０１と、後述する第３当接面９ｇが設けられて筒体７０１の外側に嵌まるリング体７０２とからなる。ここで、前記通孔７ｃは、筒体７０１に設けられる。詳細には、この通孔７ｃは、挿入孔７ａの周りの周壁７ｂにおいて、全周を３等分するように三つ設けられる。そして、これら通孔７ｃ、７ｃに対応するように前記係合部材１０が三つ設けられる。また、筒体７０１の内周、つまり挿入孔７ａの周面には、シールのためのパッキン３１が設けられている。また、筒体７０１の外周には、鍔部７ｄが設けられている。リング体７０２は、その内周が、内径が変化する段付き孔７ｅとなって、その段付き孔７ｅの段部７ｆに、筒体７０１の鍔部７ｄが当たるようにして、これら筒体７０１とリング体７０２とは組み付けられる。そして、第１部材７としての、筒体７０１とリング体７０２とは、一体となって、第１孔６ａ内を、第１方向１１に移動可能となっている。ここで、リング体７０２は、その外周面に縦溝７ｇを有しており、固定具本体６（詳細には、本体６０１）にねじ込まれて前記縦溝７ｇに先端部分が嵌まるガイドねじ２０によって、回り止めされる（図３参照）。そして、第１孔６ａ内において、弾性部材としての第１のコイルスプリング２１が、第１部材７（詳細には、筒体７０１の鍔部７ｄ）と、第２補助部材６０３との間に組み込まれ、第１部材７を、前記第１方向１１の一側とは反対の他側を向く他方の方向１１ｂ（図示実施の形態においては、上方）に弾性付勢する。 The first member 7 includes a cylindrical body 701 extending in the first direction 11 and having an inner hole serving as the insertion hole 7a, and a ring body that is provided with a third contact surface 9g described later and fits outside the cylindrical body 701. 702. Here, the through hole 7 c is provided in the cylindrical body 701. Specifically, the three through holes 7c are provided in the peripheral wall 7b around the insertion hole 7a so as to divide the entire circumference into three equal parts. Three engagement members 10 are provided so as to correspond to the through holes 7c and 7c. A packing 31 for sealing is provided on the inner periphery of the cylindrical body 701, that is, on the peripheral surface of the insertion hole 7a. In addition, a flange portion 7d is provided on the outer periphery of the cylindrical body 701. The ring body 702 has a stepped hole 7e whose inner circumference changes in inner diameter, and the flanged part 7d of the cylindrical body 701 contacts the stepped part 7f of the stepped hole 7e so that these cylindrical bodies 701 are in contact with each other. And the ring body 702 are assembled. The cylindrical body 701 and the ring body 702 as the first member 7 are integrally movable in the first direction 11 in the first hole 6a. Here, the ring body 702 has a vertical groove 7g on the outer peripheral surface thereof, and the guide screw 20 is screwed into the fixture main body 6 (specifically, the main body 601) and the tip portion is fitted into the vertical groove 7g. To prevent rotation (see FIG. 3). And in the 1st hole 6a, the 1st coil spring 21 as an elastic member is integrated between the 1st member 7 (specifically the collar part 7d of the cylindrical body 701), and the 2nd auxiliary member 603. Thus, the first member 7 is elastically biased in the other direction 11b (upward in the illustrated embodiment) facing the other side opposite to one side of the first direction 11.

この第１部材７は、第１方向１１における前記一方の方向１１ａへの移動によって、第１位置（図４、図５参照）から第２位置（図６参照）に移動することができ、反対に、第１方向１１における前記他方の方向１１ｂへの移動によって、前記第２位置（図６参照）から前記第１位置（図４、図５参照）に移動することができる。ここで、図４および図５に示すように、第１部材７が、第１位置に位置するときには、通孔７ｃ、７ｃとともに係合部材１０、１０は、案内面６ｄにおける第１案内面６ｆと対向位置して、それら係合部材１０、１０は、挿入孔７ａ側に突出しないように通孔７ｃ、７ｃから案内面６ｄ側に突出することが可能であって、連結部材３を挿入孔７ａに挿入したり挿入孔７ａから引き出したりすることができる。そして、図６に示すように、第１部材７が、第２位置に位置するときには、通孔７ｃ、７ｃとともに係合部材１０、１０は、第２案内面６ｇと対向位置して、それら係合部材１０、１０は、挿入孔７ａ内へ突出し、連結部材３（詳細には、係合凹部３ａ）に係合する。 The first member 7 can be moved from the first position (see FIGS. 4 and 5) to the second position (see FIG. 6) by moving in the first direction 11 in the one direction 11a. In addition, the movement in the first direction 11 in the other direction 11b can move from the second position (see FIG. 6) to the first position (see FIGS. 4 and 5). Here, as shown in FIGS. 4 and 5, when the first member 7 is located at the first position, the engaging members 10, 10 together with the through holes 7c, 7c are connected to the first guide surface 6f in the guide surface 6d. The engaging members 10 and 10 can project from the through holes 7c and 7c to the guide surface 6d side so as not to project to the insertion hole 7a, and the connecting member 3 can be inserted into the insertion hole 7a. It can be inserted into 7a or pulled out from the insertion hole 7a. As shown in FIG. 6, when the first member 7 is positioned at the second position, the engaging members 10 and 10 together with the through holes 7c and 7c are positioned opposite to the second guide surface 6g, The combined members 10 and 10 protrude into the insertion hole 7a and engage with the connecting member 3 (specifically, the engaging recess 3a).

ところで、第１部材７の挿入孔７ａには、第１方向１１に移動可能に挿入されて前記第１方向１１における前記他方の方向１１ｂに、第２のコイルスプリング２２によって弾性付勢された、保護栓２３が設けられており、前記連結部材３は、この保護栓２３を押し込むようにして、挿入孔７ａに挿入される。ここにおいて、保護栓２３は、下端に側方に突出する鍔部２３ａを有しており、この鍔部２３ａが挿入孔７ａに設けられた段部７ｈに掛かることで、この保護栓２３は、上方に抜け出さないように止められる。そして、このとき、保護栓２３は、第１孔６ａの開口部を通して、若干上方に突出している。また、前記第２のコイルスプリング２２は、下側が、第２補助部材６０３に螺合するようにして取り付けられた支持部材２４によって支持される。 By the way, the insertion hole 7a of the first member 7 is movably inserted in the first direction 11 and elastically biased by the second coil spring 22 in the other direction 11b in the first direction 11. A protective plug 23 is provided, and the connecting member 3 is inserted into the insertion hole 7 a so as to push the protective plug 23. Here, the protective plug 23 has a flange portion 23a protruding laterally at the lower end, and the protective plug 23 is formed by hanging the flange portion 23a on a step portion 7h provided in the insertion hole 7a. It is stopped so as not to escape upward. At this time, the protective plug 23 protrudes slightly upward through the opening of the first hole 6a. The lower side of the second coil spring 22 is supported by a support member 24 attached so as to be screwed to the second auxiliary member 603.

第２部材８は、第２方向１２に延びて前記雄ねじ部８ａが設けられたシャフト８０１と、前記回動操作部８ｂが設けられた操作部材８０２と、先端部材８０３とを有している。ここにおいて、シャフト８０１には、側方に突出する鍔部８ｃが設けられており、この鍔部８ｃが、固定具本体６に設けられた第１および第２ダンパー２５、２６と対向位置することで、シャフト８０１つまりは第２部材８は、第２方向１２の移動距離が制限される。操作部材８０２は、筒状に形成されて、後部側が、固定具本体６から外部に露出して、例えば断面六角形状の外形を有する前記回動操作部８ｂとなっている。この操作部材８０２は、シャフト８０１の後端側においてそのシャフト８０１（詳細には、雄ねじ部８ａ）に螺合している。そして、シャフト８０１の後端には、そのシャフト８０１と操作部材８０２とを回り止めするワッシャー２７が嵌められ、さらにそのワッシャー２７を抜け止めするように、止め輪２８が嵌められる。こうして、シャフト８０１と操作部材８０２とは、ワッシャー２７を介すことで、一体化される。先端部材８０３は、シャフト８０１の先端部分に、第２方向１２に移動可能に嵌合する。そして、この先端部材８０３の外周に設けられた段部８ｄとシャフト８０１の鍔部８ｃとの間には第３のコイルスプリング２９が介在しており、このコイルスプリング２９によって、先端部材８０３とシャフト８０１とは、互いに離れる方向に弾性付勢される。但し、先端部材８０３には、第１部材７と後述する伝達部材９０１を介して、第１のコイルスプリング２１による付勢力が作用しており、この付勢力の作用が第３のコイルスプリング２９の付勢力よりも大きいため、通常は、先端部材８０３とシャフト８０１とは、離れることはなく、第２方向１２の移動に対して一体となって動く。 The second member 8 has a shaft 801 extending in the second direction 12 and provided with the male screw portion 8a, an operation member 802 provided with the turning operation portion 8b, and a tip member 803. Here, the shaft 801 is provided with a flange portion 8c that protrudes to the side, and the flange portion 8c is opposed to the first and second dampers 25 and 26 provided on the fixture body 6. Thus, the movement distance of the shaft 801, that is, the second member 8 in the second direction 12 is limited. The operation member 802 is formed in a cylindrical shape, and the rear side is exposed to the outside from the fixture main body 6 to form the rotation operation portion 8b having an outer shape having a hexagonal cross section, for example. The operation member 802 is screwed to the shaft 801 (specifically, the male screw portion 8a) on the rear end side of the shaft 801. A washer 27 that prevents the shaft 801 and the operation member 802 from rotating is fitted to the rear end of the shaft 801, and a retaining ring 28 is fitted to prevent the washer 27 from coming off. Thus, the shaft 801 and the operation member 802 are integrated with each other through the washer 27. The tip member 803 is fitted to the tip portion of the shaft 801 so as to be movable in the second direction 12. A third coil spring 29 is interposed between the step 8d provided on the outer periphery of the tip member 803 and the flange portion 8c of the shaft 801, and the tip member 803 and the shaft are interposed by the coil spring 29. 801 is elastically biased in directions away from each other. However, the urging force of the first coil spring 21 acts on the tip member 803 via the first member 7 and a transmission member 901 described later, and the action of this urging force acts on the third coil spring 29. Since it is larger than the urging force, the tip member 803 and the shaft 801 normally do not separate from each other and move together with respect to the movement in the second direction 12.

そして、この第２部材８は、回動操作部８ｂをねじ軸心１３回りの一方向に回動することによる、前記第２方向１２の一側を向く一方の方向１２ａへの移動によって、後退位置（図４、図５参照）から前進位置（図６参照）に移動することができ、反対に、回動操作部８ｂをねじ軸心１３回りの他方向に回動することによる、前記第２方向１２の一側とは反対の他側を向く他方の方向１２ｂへの移動によって、前記前進位置（図６参照）から前記後退位置（図４、図５参照）に移動することができる。なお、回動操作部８ｂをねじ軸心１３回りに回動するに当たっては、スパナ等の手動工具を用いたり、ハンドタイプのインパクトレンチとかナットランナー（電動、エアー等のトルクレンチ）等を用いたり、インパクトレンチとかナットランナー等をロボットとかマシニングセンター等に取り付けて用いたりすることもできる。 Then, the second member 8 moves backward by moving in one direction 12a facing one side of the second direction 12 by rotating the rotation operation portion 8b in one direction around the screw axis 13. The position can be moved from the position (see FIGS. 4 and 5) to the forward position (see FIG. 6). By moving in the other direction 12b facing the other side opposite to the one side in the two directions 12, it is possible to move from the forward position (see FIG. 6) to the backward position (see FIGS. 4 and 5). In order to rotate the rotation operation unit 8b around the screw shaft center 13, a manual tool such as a spanner or a hand type impact wrench or a nut runner (electric or pneumatic torque wrench) or the like is used. An impact wrench or nut runner can be attached to a robot or machining center.

変換手段９は、前記伝達部９ａと、前記第１のコイルスプリング２１からなる。ここで、伝達部９ａは、第１部材７と第２部材８との間に介在する断面三角形の伝達部材９０１を備える。この伝達部材９０１は、第２孔６ｂ側に位置して前記断面三角形を構成する第１面９ｂと、第１孔６ａ側であって第１方向１１における前記他方の方向１１ｂ側に位置して前記断面三角形を構成する第２面９ｃと、第１孔６ａ側であって第１方向１１における前記一方の方向１１ａ側に位置して前記断面三角形を構成する第３面９ｄとを有する。そして、前記伝達部９ａは、この伝達部材９０１と、第２部材８（図示実施の形態においては、先端部材８０３）の、前記第１面９ｂと当接する第１当接面９ｅと、第１孔６ａ（図示実施の形態においては、第２リング６０６）の、前記第２面９ｃと当接する第２当接面９ｆと、第１部材７（図示実施の形態においては、リング体７０２）の、前記第３面９ｄと当接する第３当接面９ｇとからなる。詳細には、伝達部材９０１は、断面鋭角三角形、特に断面正三角形状をしている。そして、伝達部材９０１は、第１面９ｂが、第２方向１２に直交するように（つまりは、第１方向１１に沿うように）位置する。また、第１当接面９ｅは、第１面９ｂと平行な平面からなり、第２当接面９ｆは、第２面９ｃと平行な平面からなり、そして、第３当接面９ｇは、第３面９ｄと平行な平面からなる。そして、第１面９ｂと第１当接面９ｅとは、第１面９ｂに沿う方向に（つまりは、第１当接面９ｅに沿う方向に）、相対的にスライド可能となり、第２面９ｃと第２当接面９ｆとは、第２面９ｃに沿う方向に（つまりは、第２当接面９ｆに沿う方向に）、相対的にスライド可能となり、第３面９ｄと第３当接面９ｇとは、第３面９ｄに沿う方向に（つまりは、第３当接面９ｇに沿う方向に）、相対的にスライド可能となっている。 The conversion means 9 includes the transmission portion 9 a and the first coil spring 21. Here, the transmission unit 9 a includes a transmission member 901 having a triangular cross section interposed between the first member 7 and the second member 8. The transmission member 901 is located on the second hole 6b side and forms the cross-sectional triangle, and the transmission member 901 is located on the first hole 6a side and the other direction 11b side in the first direction 11. It has the 2nd surface 9c which comprises the said cross-sectional triangle, and the 3rd surface 9d which is located in the said one direction 11a side in the 1st direction 11 on the 1st hole 6a side, and comprises the said cross-sectional triangle. The transmission portion 9a includes the transmission member 901, a first contact surface 9e that contacts the first surface 9b of the second member 8 (the tip member 803 in the illustrated embodiment), and a first The second contact surface 9f of the hole 6a (second ring 606 in the illustrated embodiment) that contacts the second surface 9c and the first member 7 (ring body 702 in the illustrated embodiment). The third contact surface 9g contacts the third surface 9d. Specifically, the transmission member 901 has an acute-angled cross section, particularly, a regular equilateral triangle. The transmission member 901 is positioned such that the first surface 9b is orthogonal to the second direction 12 (that is, along the first direction 11). The first contact surface 9e is a plane parallel to the first surface 9b, the second contact surface 9f is a plane parallel to the second surface 9c, and the third contact surface 9g is It consists of a plane parallel to the third surface 9d. The first surface 9b and the first contact surface 9e are relatively slidable in the direction along the first surface 9b (that is, in the direction along the first contact surface 9e), and the second surface 9c and the second contact surface 9f are relatively slidable in a direction along the second surface 9c (that is, in a direction along the second contact surface 9f), and the third surface 9d and the third contact surface 9f The contact surface 9g is relatively slidable in the direction along the third surface 9d (that is, in the direction along the third contact surface 9g).

そこで、第２部材８の回動操作部８ｂを回動操作して、第２部材８を第２方向１２に延びるねじ軸心１３回りに回動すると、第２部材８は、回動しながらその第２方向１２に移動する。そして、この第２部材８が第２方向１２に移動すると、変換手段９を介して、第１部材７が、第２方向１２と交差する（図示実施の形態においては、直交する）第１方向１１に移動する。すなわち、第２部材８の第２方向１２への移動に伴って、その第２部材８の第１当接面９ｅと、固定具本体６における第１孔６ａに設けられた第２当接面９ｆとの間に介在する伝達部材９０１は、第２方向１２に移動するとともに第１方向１１に移動する。そして、この伝達部材９０１の第３面９ｄと当接する第３当接面９ｇを有する第１部材７は、伝達部材９０１の、第２方向１２の移動と第１方向１１の移動を受けて、第１方向１１に移動する。こうして、第２部材８が、第２方向１２における後退位置に位置するときには、第１部材７は、第１方向１１における第１位置に位置し（図４、図５参照）、第２部材８が、第２方向１２における前進位置に位置するときには、第１部材７は、第１方向１１における第２位置に位置する（図６参照）。 Therefore, when the rotation member 8b of the second member 8 is rotated to rotate the second member 8 around the screw axis 13 extending in the second direction 12, the second member 8 is rotated. It moves in the second direction 12. And if this 2nd member 8 moves to the 2nd direction 12, the 1st member 7 will cross | intersect the 2nd direction 12 via the conversion means 9 (it orthogonally crosses in embodiment shown in figure) 1st direction Move to 11. That is, as the second member 8 moves in the second direction 12, the first contact surface 9 e of the second member 8 and the second contact surface provided in the first hole 6 a in the fixture body 6. The transmission member 901 interposed between the first and second members 9 f moves in the second direction 12 and moves in the first direction 11. The first member 7 having the third contact surface 9g that contacts the third surface 9d of the transmission member 901 receives the movement of the transmission member 901 in the second direction 12 and the movement of the first direction 11, Move in the first direction 11. Thus, when the second member 8 is located at the retracted position in the second direction 12, the first member 7 is located at the first position in the first direction 11 (see FIGS. 4 and 5), and the second member 8. However, when it is located at the forward movement position in the second direction 12, the first member 7 is located at the second position in the first direction 11 (see FIG. 6).

ここにおいて、第１部材７が、前記第１位置（図５参照）から前記第２位置（図６参照）に移動すべく、連結部材３を挿入孔７ａに挿入する方向となる、前記第１方向１１における一方の方向１１ａへ移動すると、その第１部材７とともに係合部材１０、１０がその一方の方向１１ａに移動する。そして、これら移動する係合部材１０、１０は、第１孔６ａに設けられた案内面６ｄに案内されて、挿入孔７ａ内へ突出する。こうして、係合部材１０、１０が、挿入孔７ａ内へ突出すると、それら係合部材１０、１０は、挿入孔７ａに挿入された連結部材３（詳細には、連結部材３の係合凹部３ａ）に係合する。このようにして、ワーク２に設けられた連結部材３が、固定具４に取付固定され、ひいては、この固定具４を介して、ワーク２が取付具ベース１に固定される。 Here, in order to move the first member 7 from the first position (see FIG. 5) to the second position (see FIG. 6), the connecting member 3 is inserted into the insertion hole 7a. When moving in one direction 11a in the direction 11, the engaging members 10 and 10 together with the first member 7 move in the one direction 11a. And these engaging members 10 and 10 which move are guided by the guide surface 6d provided in the 1st hole 6a, and protrude in the insertion hole 7a. Thus, when the engaging members 10 and 10 protrude into the insertion hole 7a, the engaging members 10 and 10 are connected to the connecting member 3 (specifically, the engaging recess 3a of the connecting member 3). ). In this way, the connecting member 3 provided on the workpiece 2 is attached and fixed to the fixture 4, and thus the workpiece 2 is fixed to the fixture base 1 via the fixture 4.

反対に、第１部材７が、前記第２位置（図６参照）から前記第１位置（図５参照）に移動すべく、前記第１方向１１における他方の方向１１ｂへ移動すると、その第１部材７とともに係合部材１０、１０がその他方の方向１１ｂに移動し、係合部材１０、１０は、案内面６ｄにおける第１案内面６ｆと対向位置する。こうして、連結部材３への係合部材１０、１０の係合が解除されて、連結部材３を挿入孔７ａから引き出す、つまり、ワーク２を固定具４から離して、そのワーク２を取付具ベース１から取り外すことができる。 On the contrary, when the first member 7 moves from the second position (see FIG. 6) to the first position (see FIG. 5) to the other direction 11b in the first direction 11, the first member 7 moves to the first position. The engaging members 10 and 10 move in the other direction 11b together with the member 7, and the engaging members 10 and 10 are positioned opposite to the first guide surface 6f in the guide surface 6d. Thus, the engagement of the engaging members 10 and 10 with the connecting member 3 is released, and the connecting member 3 is pulled out from the insertion hole 7a, that is, the work 2 is separated from the fixture 4, and the work 2 is attached to the fixture base. 1 can be removed.

この固定具４によると、連結部材３を挿入したり引き出したりする方向となる第１方向１１と、第２部材８を回動するねじ軸心１３の方向となる第２方向１２とが交差するため（図示実施の形態においては、直交するため）、第２部材８における回動操作部８ｂの操作が容易となり、ワーク２に対する連結部材３の配置位置の制限を低減することができる。 According to the fixture 4, the first direction 11, which is the direction in which the connecting member 3 is inserted or pulled out, and the second direction 12, which is the direction of the screw shaft center 13 that rotates the second member 8, intersect. For this reason (because they are orthogonal in the illustrated embodiment), the operation of the rotation operation portion 8b in the second member 8 is facilitated, and the restriction on the arrangement position of the connecting member 3 with respect to the workpiece 2 can be reduced.

また、第１部材７とともに係合部材１０、１０が、第１方向１１における前記一方の方向１１ａへ移動して、係合部材１０、１０が挿入孔７ａ内へ突出して連結部材３の係合凹部３ａに係合すると、それら係合部材１０、１０は、連結部材３を第１方向１１における前記一方の方向１１ａ、つまりは、連結部材３を引き込む引込み方向に付勢することとなる。こうして、ワーク２を、連結部材３を介して強固に固定することができる。 Further, the engaging members 10, 10 move together with the first member 7 in the one direction 11 a in the first direction 11, and the engaging members 10, 10 protrude into the insertion hole 7 a to engage the connecting member 3. When engaged with the recess 3 a, the engaging members 10 and 10 urge the connecting member 3 in the one direction 11 a in the first direction 11, that is, in the retracting direction in which the connecting member 3 is pulled. In this way, the workpiece 2 can be firmly fixed via the connecting member 3.

また、挿入孔７ａには、保護栓２３が設けられており、挿入孔７ａに連結部材３が挿入される前に、その挿入孔７ａに埃等が入るのを防ぐことができる。そして、この保護栓２３は、挿入孔７ａ内で弾性付勢されており、連結部材３は、保護栓２３を押し込むようにして、挿入孔７ａに挿入される。このため、連結部材３を挿入孔７ａに挿入するにあたって、保護栓２３を取り外す必要がなく、取り扱いが容易である。 The insertion hole 7a is provided with a protective plug 23, which can prevent dust and the like from entering the insertion hole 7a before the connecting member 3 is inserted into the insertion hole 7a. The protective plug 23 is elastically biased in the insertion hole 7a, and the connecting member 3 is inserted into the insertion hole 7a so as to push in the protective plug 23. For this reason, when inserting the connection member 3 in the insertion hole 7a, it is not necessary to remove the protective plug 23, and handling is easy.

なお、本発明は、上述した実施の形態に限定されるわけではなく、その他種々の変更が可能である。例えば、固定具４は、取付具ベース１の上側に取り付けられる構造となっていなくとも、図７および図８に示すように、取付具ベース１の下側に取り付けられる構造となっていてもよい。ここにおいて、固定具本体６（つまりは、固定具４）は、固定具本体６とサポータ３５とで、取付具ベース１を挟み込むようにして、その取付具ベース１に取り付けられる。詳細には、取付具ベース１には、取付孔１ｖが明けられている。この取付孔１ｖは、段付き孔からなり、その段部１ｗを境にして、下側の径小孔１ｘと、上側の径大孔１ｙとから構成される。そして、固定具４においては、固定具本体６を構成する第１補助部材６０２は、下端部分に、フランジ部６ｘを有している。そして、このフランジ部６ｘの上面が取付具ベース１の下面に宛がわれて、第１補助部材６０２の先端側が、径小孔１ｘに下から挿入される。そして、サポータ３５は、盤状に形成されており、取付具ベース１の径大孔１ｙに上から挿入されて段部１ｗに載せられる。そして、ボルト等の固着部材１９が、上から、サポータ３５と取付具ベース１を貫通し、固定具本体６にねじ込まれ、こうして、固定具本体６（つまりは、固定具４）は、取付具ベース１に、着脱可能に取付固定される。ここで、サポータ３５には、貫通孔３５ａが明けられており、この貫通孔３５ａを通って、連結部材３は、挿入孔７ａに挿入される。そして、サポータ３５の上面は、ワーク２（図示実施の形態においては、ワーク２の下面２ｂ）を受ける受面３５ｂとなっている。ところで、この実施の形態においては、サポータ３５は、独立した部材からなるが、このサポータ３５部分が、始めから取付具ベース１と一体となっていてもよい。すなわち、サポータ３５部分が、取付具ベース１の一部からなっていても構わない。 In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, the fixture 4 may not be structured to be attached to the upper side of the fixture base 1, but may be structured to be attached to the lower side of the fixture base 1 as shown in FIGS. . Here, the fixture main body 6 (that is, the fixture 4) is attached to the fixture base 1 by sandwiching the fixture base 1 between the fixture main body 6 and the supporter 35. Specifically, the attachment base 1 has an attachment hole 1v. The mounting hole 1v is a stepped hole, and includes a lower diameter small hole 1x and an upper diameter large hole 1y with the stepped portion 1w as a boundary. And in the fixture 4, the 1st auxiliary member 602 which comprises the fixture main body 6 has the flange part 6x in a lower end part. And the upper surface of this flange part 6x is addressed to the lower surface of the fixture base 1, and the front end side of the 1st auxiliary member 602 is inserted from the bottom into the small diameter hole 1x. The supporter 35 is formed in a disk shape, and is inserted into the large diameter hole 1y of the fixture base 1 from above and placed on the stepped portion 1w. Then, the fixing member 19 such as a bolt penetrates the supporter 35 and the fixture base 1 from above and is screwed into the fixture main body 6. Thus, the fixture main body 6 (that is, the fixture 4) is attached to the fixture The base 1 is detachably mounted and fixed. Here, a through hole 35a is opened in the supporter 35, and the connecting member 3 is inserted into the insertion hole 7a through the through hole 35a. The upper surface of the supporter 35 is a receiving surface 35b that receives the workpiece 2 (the lower surface 2b of the workpiece 2 in the illustrated embodiment). By the way, in this embodiment, although the supporter 35 consists of an independent member, this supporter 35 part may be united with the fixture base 1 from the beginning. That is, the supporter 35 portion may be a part of the fixture base 1.

また、固定具４は、その固定具単独で用いられてもよいが、固定具４を、遠隔操作ユニットと組み合わせて用いてもよい。図９〜図１１を用いて説明すると、図９において、ワーク２の側端（詳細には左端）に近い左側の連結部材３に対しては、固定具４は、固定具単独で用いられているが、ワーク２の側端（詳細には右端）から遠い右側の連結部材３に対しては、固定具４は、その固定具４（詳しくは、固定具４の回動操作部８ｂ）に連結される、遠隔操作ユニット４１と組み合わされて用いられる。この遠隔操作ユニット４１は、取付具ベース１に着脱可能に取付固定される基台４２と、延長シャフト４３とを備えている。ここで、基台４２には、延長シャフト４３が回動可能に挿入される軸受孔４２ａが設けられている。そして、基台４２は、横に突設されたフランジ部４２ｂ、４２ｂを有している。このフランジ部４２ｂには、取付け用の孔４２ｃが明けられており、この孔４２ｃに、固着部材としての例えばボルト４４が挿入されて取付具ベース１にねじ込まれることで、基台４２は、取付具ベース１に取り付けられる。また、延長シャフト４３は、棒状のシャフト本体４３ａと、連結具としての筒状のソケット４３ｂとからなる。さらに、シャフト本体４３ａは、一端側の、断面六角形状をした遠隔回動操作部４３ｃと、中間の、断面円形形状をした挿通部４３ｄと、他端側の、断面六角形状をした嵌合部４３ｅと、その嵌合部４３ｅと挿通部４３ｄとの間の鍔部４３ｆとからなっている。そして、ソケット４３ｂは、その筒内が断面六角形状に形成されている。そこで、シャフト本体４３ａの嵌合部４３ｅに、ソケット４３ｂの一端側が嵌まることで、これらシャフト本体４３ａとソケット４３ｂとは一体化される。そして、これらシャフト本体４３ａとソケット４３ｂとからなる延長シャフト４３は、そのシャフト本体４３ａの挿通部４３ｄ部分が基台４２の軸受孔４２ａに嵌まり、その軸受孔４２ａの軸心４５回りに回動することができる。この遠隔操作ユニット４１は、ソケット４３ｂの他端側が、固定具４における第２部材８の回動操作部８ｂに嵌められるようにして、取付具ベース１に前記ボルト４４を用いて取付固定される。このとき、軸受孔４２ａの軸心４５は、固定具４におけるねじ軸心１３の延長線上にあり、延長シャフト４３の遠隔回動操作部４３ｃを回動操作することで、第２部材８を回動することができる。こうして、遠隔操作ユニット４１を用いることで、ワーク２等に邪魔されることなく、固定具４を遠隔操作することができる。そして、このように、固定具４と遠隔操作ユニット４１とを組み合わせて用いることができるが、固定具４における第２部材８と、遠隔操作ユニット４１における延長シャフト４３とを一体的に見ることで、この延長シャフト４３を第２部材８の一部とみなすとともに、遠隔回動操作部４３ｃを固定具４における回動操作部８ｂとみなしてもよい。 In addition, the fixture 4 may be used alone, but the fixture 4 may be used in combination with a remote operation unit. 9 to FIG. 11, in FIG. 9, the fixing tool 4 is used alone for the connecting member 3 on the left side near the side end (specifically, the left end) of the work 2. However, for the connecting member 3 on the right side far from the side end (specifically, the right end) of the work 2, the fixing tool 4 is connected to the fixing tool 4 (specifically, the rotating operation portion 8b of the fixing tool 4).

It is attached to the tool base 1. The extension shaft 43 includes a rod-shaped shaft main body 43a and a cylindrical socket 43b as a connecting tool. Furthermore, the shaft main body 43a includes a remote rotation operation portion 43c having a hexagonal cross section on one end side, an intermediate insertion portion 43d having a circular cross section and a fitting portion having a hexagonal cross section on the other end side. 43e and a flange portion 43f between the fitting portion 43e and the insertion portion 43d. The socket 43b has a hexagonal cross section inside the cylinder. Therefore, the shaft main body 43a and the socket 43b are integrated by fitting one end side of the socket 43b into the fitting portion 43e of the shaft main body 43a. The extension shaft 43 composed of the shaft main body 43a and the socket 43b has an insertion portion 43d portion of the shaft main body 43a fitted in the bearing hole 42a of the base 42, and rotates around the axis 45 of the bearing hole 42a. can do. The remote operation unit 41 is attached and fixed to the fixture base 1 using the bolt 44 so that the other end side of the socket 43b is fitted into the rotation operation portion 8b of the second member 8 of the fixture 4. . At this time, the shaft center 45 of the bearing hole 42 a is on the extension line of the screw shaft center 13 in the fixture 4, and the second member 8 is rotated by rotating the remote rotation operation portion 43 c of the extension shaft 43. Can move. Thus, by using the remote operation unit 41, the fixture 4 can be remotely operated without being disturbed by the workpiece 2 or the like. In this way, the fixture 4 and the remote operation unit 41 can be used in combination. However, when the second member 8 in the fixture 4 and the extension shaft 43 in the remote operation unit 41 are viewed integrally, The extension shaft 43 may be regarded as a part of the second member 8, and the remote rotation operation unit 43 c may be regarded as the rotation operation unit 8 b in the fixture 4.

また、連結部材３は、螺合によりワーク２に取り付けられるねじ部材からならなくとも、図１２に示すように、ワーク２に設けられた貫通孔２ｃに通される、雄ねじを備えないピンからなっていてもよい。詳しくは、この連結部材３は、前記貫通孔２ｃおよび固定具４における挿入孔７ａに挿入される軸部３０１と、その軸部３０１よりも径大な（詳細には、貫通孔２ｃよりも径大な）頭部３０２とからなる。こうして、この連結部材３は、その頭部３０２が貫通孔２ｃの周縁に掛けられ、ワーク２に着脱可能に取り付けられる。図示実施の形態においては、ワーク２の上面２ｄであって貫通孔２ｃの周縁には、座ぐりによって形成された座面２ｅが設けられており、この座面２ｅに前記頭部３０２が当接する。もちろん、貫通孔２ｃの周縁を座ぐることなく、ワーク２の上面２ｄをそのまま、頭部３０２が当接する座面として機能させても構わない。 Further, the connecting member 3 does not include a screw member attached to the work 2 by screwing, but includes a pin not provided with a male screw that is passed through a through hole 2c provided in the work 2, as shown in FIG. It may be. Specifically, the connecting member 3 includes a shaft portion 301 to be inserted into the through hole 2c and the insertion hole 7a in the fixture 4, and a diameter larger than that of the shaft portion 301 (specifically, a diameter larger than that of the through hole 2c). Large) head 302. Thus, the head 302 of the connecting member 3 is attached to the work 2 so as to be detachable, with the head 302 hung on the periphery of the through hole 2c. In the illustrated embodiment, a seating surface 2e formed by a spot facing is provided on the upper surface 2d of the work 2 and on the periphery of the through hole 2c, and the head 302 is brought into contact with the seating surface 2e. . Of course, the upper surface 2d of the work 2 may be used as it is as a seating surface against which the head 302 abuts without sitting around the periphery of the through hole 2c.

また、被固定物は、ワーク２以外の、治具、取付具あるいは金型とかの、その他の被固定物であっても構わない。また、連結部材３は、ワーク２等の被固定物に取り付けられた、あるいは一体的に設けられた、被固定物側に設けられる部材であってもよく、その連結部材３を介して、被固定物を取付具ベース１等の取付支持体に固定するようにしても構わない。 Further, the object to be fixed may be other objects to be fixed such as a jig, a fixture or a mold other than the workpiece 2.
