<P>PROBLEM TO BE SOLVED: To provide a clamp device capable of reducing man-hour in manufacturing the device and reducing the cost of the device itself. <P>SOLUTION: The clamp device embraces a plate-like workpiece (W) set in a horizontal attitude from the vertical direction for clamping, and includes a piston (3) vertically moving inside a cylinder (1), an upper clamper (5) connected to a rod (4) that is integrated with the piston (3) in a connection section arranged on one end side with one end side vertically moving with the rod (4), and a lower clamper (6) rotatably connected to a case (2) in a rotation support section (RK2) arranged on one end side and relatively rotatably connected to an intermediate section of the upper clamper (5) in a rotation connection section (RK3) in the intermediate section. Also, the clamp device includes a rotation angle restricting section (RK5) restricting the rotation angle range of the lower clamper (6) by restricting downward rotation of the lower clamper (6) around the rotation support section (RK2) accompanying rising of the piston (3) and by restricting upward rotation of the lower clamper (6) around the rotation support section (RK2) accompanying descending of the piston (3). <P>COPYRIGHT: (C)2013,JPO&INPIT |
