GRIPPING DEVICE

To provide a gripping device capable of gripping work-pieces having different sizes.SOLUTION: A gripping device includes: a reciprocating driven member; and a pair of rotation sections 3a and 3b. Each rotation section 3a and 3b has body members 5a and 5b, gripping members 38 for gripping a work-piece W1, and a link mechanism section 7. The body members 5a and 5b can rotate in a range of a prescribed angle around a rotary shaft 25, and the body members 5a and 5b are rotated in the range of the prescribed angle by being pressed when the driven member moves in one direction. The gripping members 38 are installed so that the gripping members can be reciprocated with respect to the body members 5a and 5b and are connected to the driven member through the link mechanism section 7. When each rotation section 3a and 3b rotates, a non-opposite state and an opposite state can be switched and the holding members 38 are opposed to each other in the opposite state. When the non-opposite state is switched to the opposite state and further the driven member moves, the interval of each gripping member 38 is narrowed.SELECTED DRAWING: Figure 1 【課題】大きさの相違するワークを把持することができる把持装置を提供することである。【解決手段】往復移動する被駆動部材と、一対の回動部３ａ、３ｂを有する。各回動部３ａ、３ｂは、本体部材５ａ、５ｂと、ワークＷ１を把持する把持部材３８と、リンク機構部７を有する。本体部５ａ、５ｂは回動軸２５を中心に所定の角度の範囲で回動が可能であり、被駆動部材が一方向に移動すると本体部材５ａ、５ｂが押圧されて所定の角度の範囲で回動し、把持部材３８は、本体部材５ａ、５ｂに対して往復移動可能に設置されていると共に、リンク機構部７を介して被駆動部材と連結されており、各回動部３ａ、３ｂが回動すると、非対向状態と対向状態を切り替えることができ、把持部材３８同士は対向状態で互いに対向しており、非対向状態から対向状態に切り替わって、さらに被駆動部材が移動すると、各把持部３８同士の間隔が狭まる。【選択図】図１
