Claims

[Scope of utility model registration request]

This is a clamping device for clamping a workpiece W onto a jig table 3. A single cylinder device C is built in the jig table 3, and the piston rod 11 of this cylinder device C is connected to the jig table 3. A plurality of floating springs 15 are made to protrude from the lower surface so as to be movable back and forth, and a floating plate 13 is attached to the protruding end of the floating plate 13.
The lower ends of a plurality of push rods 16 slidably penetrating the jig table 3 are connected to the floating plate 13 at intervals in the circumferential direction by a pivot support 25. The base end of the clamp piece 18 extending above the jig table 3 is connected to the upper end of each push rod 16 by a pivot 19, and the middle part of the clamp piece 18 and the jig table 3 are connected via a swing regulating link 20. and said push rod 1
6. The clamp device is characterized in that the clamp piece 18 is opened and closed by the vertical movement of the clamp member 6, so that a workpiece W placed on a jig table 3 can be clamped.
