Claims

[Claims for Utility Model Registration] One support part and another support part are provided at intervals in the main body of the device, one clamp piece is provided on the one support part, and another is provided on the other support part. The clamp pieces are arranged to face each other, and each of the clamp pieces can move away from and approach each of the support parts, and the workpiece is gripped by cooperation between the clamp pieces and the support part. In the clamp device, a sub-link disposed near the first support portion and a long link disposed across the device body are swingably attached to the device body. The one clamp piece is swingably attached to the sub-link and can be moved away from and approached the one support part, and the base end of the one clamp piece has a cylinder rod of an actuating cylinder. are rotatably connected, the operating cylinder is suspended from the one clamp piece, and the other clamp is spaced apart from the other support part via a link mechanism including the elongated link. one end of the elongated link is rotatably connected to the cylinder body of the working cylinder, and a pivot axis of the elongated link relative to the cylinder body is above and above the center of gravity of the working cylinder. A stopper is disposed substantially intersecting a vertical line including the center of gravity, and is provided on a path from the link mechanism to the other clamp piece to restrict the position of the other clamp piece at a position apart from the other support part. A clamping device characterized by:
