Abstract
A clamping device includes a cylinder, a base body, a movable plate, and holding pins. The movable plate is attached to the base body substantially parallel thereto via two pairs of link arms. The movable plate moves along the operating direction of the cylinder. The movable plate can abut against a width-direction side surface of a workpiece. The holding pins are attached to the movable plate. The holding pins abut against an upper portion of the workpiece.
Claims4
A clamping device that positions and fixes a workpiece, the clamping device comprising:
- a cylinder configured to move forward and backward relative to the workpiece;
- a base body attached to a tip of the cylinder;
- a first clamping member attached to the base body substantially parallel to the base body via at least one pair of link arms, the first clamping member including an abutting surface configured to abut against a first surface of the workpiece in an operating direction of the cylinder;
- and
- a second clamping member attached to the first clamping member and extending in a direction orthogonal to the abutting surface, wherein
- one end of each of the link arms is pivotally supported by the base body, and another end of each of the link arms is pivotally supported by the first clamping member, and
- when the first clamping member abuts against the workpiece and each of the link arms is tilted in a manner that the another end approaches the base body, the second clamping member moves in a direction orthogonal to the operating direction and abuts against a second surface of the workpiece that is substantially orthogonal to the first surface.
