Two lids 47 are fixed to the second guide 13. The first lid 46 and the second lid 47 prevent the rotating shaft 41 and the collar 42 from being detached from the first guide 12 and the second guide 13.

以上の構成のバイスは以下の動作をする。
円板カム４０の周辺部に第１切欠４３および第２切欠４４が形成され、第１切欠４３および第２切欠４４は円板カム４０の回転中心４５を通る直径上に形成され、第１シリンダ３１が第１切欠４３に連結され、第２シリンダ３２が第２切欠４４に連結され、第１シリンダ３１および第２シリンダ３２により円板カム４０が回転する。そして、第１爪２１が第１切欠４３に連結され、第２爪２２が第２切欠４４に連結され、第１爪２１と第２爪２２が円板カム４０の回転により互いに反対方向に同じ距離移動して、第１爪２１および第２爪２２によりワーク５０を挟むことができる。 The vise configured as described above operates as follows.
A first notch 43 and a second notch 44 are formed in the periphery of the disc cam 40, and the first notch 43 and the second notch 44 are formed on a diameter passing through the rotation center 45 of the disc cam 40, and the first cylinder 31 is connected to the first cutout 43, the second cylinder 32 is connected to the second cutout 44, and the disc cam 40 is rotated by the first cylinder 31 and the second cylinder 32. The first claw 21 is connected to the first notch 43, the second claw 22 is connected to the second notch 44, and the first claw 21 and the second claw 22 are the same in opposite directions due to the rotation of the disc cam 40. The workpiece 50 can be pinched by the first claw 21 and the second claw 22 by moving the distance.

さらに、第１シリンダ３１を取り付ける第１スライダ３３に第１係合部３５が付設され、第１係合部３５が第１切欠４３に係合することにより第１シリンダ３１と第１切欠４３の連結が構成され、第２シリンダ３２を取り付ける第２スライダ３４に第２係合部３６が付設され、第２係合部３６が第２切欠４４に係合することにより第２シリンダ３２と第２切欠４４の連結が構成されるので、円板カム４０の回転により、第１スライダ３３と第２スライダ３４は反対方向に移動する。
さらに、各ガイド１２、１３に沿って移動する第１スライダ３３に取り付けられた第１シリンダ３１のピストン３１ａは各ガイド１２、１３の一方の端部に取り付けられ、各ガイド１２、１３に沿って移動する第２スライダ３４に取り付けられた第２シリンダ３２のピストン３２ａは各ガイド１２、１３の他方の端部に取り付けられ、第１シリンダ３１と第２シリンダ３２は同じ構造のものであり、第１シリンダ３１と第２シリンダ３２は同じ流体圧により駆動され、第１爪２１は第１スライダ３３に固定され、第２爪２２は第２スライダ３４に固定されるので、流体圧により第１シリンダ３１および第２シリンダ３２は同じ大きさの力で第１スライダ３３および第２スライダ３４を移動させる。 Further, a first engagement portion 35 is attached to the first slider 33 to which the first cylinder 31 is attached, and the first engagement portion 35 engages with the first notch 43, whereby the first cylinder 31 and the first notch 43. A second engaging portion 36 is attached to the second slider 34 to which the second cylinder 32 is attached, and the second engaging portion 36 engages with the second notch 44 so that the second cylinder 32 and the second cylinder 32 are connected. Since the connection of the notches 44 is configured, the first slider 33 and the second slider 34 move in opposite directions by the rotation of the disc cam 40.
Furthermore, the piston 31a of the first cylinder 31 attached to the first slider 33 that moves along the guides 12 and 13 is attached to one end of each of the guides 12 and 13, and along the guides 12 and 13 The piston 32a of the second cylinder 32 attached to the moving second slider 34 is attached to the other end of each guide 12, 13, and the first cylinder 31 and the second cylinder 32 have the same structure, The first cylinder 31 and the second cylinder 32 are driven by the same fluid pressure, the first claw 21 is fixed to the first slider 33, and the second claw 22 is fixed to the second slider 34. 31 and the second cylinder 32 move the first slider 33 and the second slider 34 with the same force.

さらに、円板カム４０の回転軸４１は横軸であり、両方のガイド１２、１３に取り付けられているので、円板カム４０を請求項１記載のバイス１０に組み込むことが容易になる。   Further, since the rotary shaft 41 of the disc cam 40 is a horizontal axis and is attached to both guides 12 and 13, it is easy to incorporate the disc cam 40 into the vise 10 according to claim 1.

なお、上記実施の形態においては、第１シリンダ３１および第２シリンダ３２を使用しているが、第１シリンダ３１および第２シリンダ３２のどちらか一方を省いた構成にすることができる。円板カム４０の各切欠４３、４４に係合する各係合部３５、３６がシンプルなため、剛性を充分とることができるためである。
また、上記実施の形態においては、円板カム４０の厚さは均一ではないが、均一の厚さにすることもできる。
また、ワーク５０は円形断面の棒状であるが、これに限定されず、種々の形状のワークを挟んで固定することができる。 In the above embodiment, the first cylinder 31 and the second cylinder 32 are used. However, either the first cylinder 31 or the second cylinder 32 can be omitted. This is because the engaging portions 35 and 36 that engage with the notches 43 and 44 of the disc cam 40 are simple, so that sufficient rigidity can be obtained.
Moreover, in the said embodiment, although the thickness of the disc cam 40 is not uniform, it can also be made into uniform thickness.
Moreover, although the workpiece | work 50 is a rod shape of a circular cross section, it is not limited to this, A workpiece | work of various shapes can be pinched and fixed.
