DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a robot hand having a rotary arm provided with a claw that can be opened and closed at the tip thereof.

ないといった欠点があった。
When a robot with a hand like the one shown in 2 is used to grip a workpiece on a pallet, the arm rotates to grip the gripped workpiece to a chuck on a lathe, etc., and the receiver transfers the workpiece, the length of the workpiece is If the length of the workpiece is short, or if the length of the revolving arm is sufficiently long, but not so much, if the length of the workpiece is long or the length of the revolving arm is short, the workpiece (5 ) enters the chuck (1) of the lathe by moving on a circular orbit, so the workpiece W cannot enter unless the chuck (1) is wide open, and even if the chuck (1) is wide open, the workpiece W cannot enter the chuck (1) of the lathe. There was a drawback that (5) could not be penetrated deeply.

また、ワーク(5)のチャック(1)内への突込み量を

、るおそれがあった。
In addition, if the rotating arm (2) is rotated to adjust the amount of thrust of the workpiece (5) into the chuck (1), the workpiece (5) inside the chuck (1) will be
) changes, so the next time you close the chuck (1) and grip the workpiece (b), the workpiece (5) will not be gripped by the chuck (1) properly, and the gripping center of the chuck (1) will not match the workpiece (5). There was a risk that the axis of the workpiece (5) would be misaligned, resulting in an insufficient grasping state.

そこで、この発明は上記開閉自在な 爪部分を旋回アームに対して直交する 方向に摺動自在になすと共に、上記摺 動自在な爪部分と旋回アーム間に爪部 分の移動手段を設けて、ワークを旋盤 等のチャック内へ直進して進入せしめ得るようになし、
上記のような欠点を解消したものである。
Therefore, the present invention makes the claw portion that can be opened and closed slidable in a direction perpendicular to the rotating arm, and also provides means for moving the claw portion between the slidable claw portion and the rotating arm. so that it can go straight into the chuck of a lathe etc.
This eliminates the drawbacks mentioned above.
