Abstract
The present invention provides a holding mechanism capable of well preventing misalignment of a workpiece even if the outer diameter of the workpiece is changed when the workpiece is supported at three points by a flat face and a V-shaped groove. Additionally, the present invention provides a holding mechanism of a transfer device capable of stably detecting a chucking error of holding claws for a workpiece.
Claims10
A holding mechanism comprising:
- a pair of holding claws that are disposed to be opposed to each other on both sides of a workpiece in a horizontal direction, a holding face of one of the holding claws being formed into a flat face, a holding face of the other holding claw being formed into a V-shaped groove;
- a driving unit that moves an output shaft forward and backward;
- and
- a link mechanism that converts a forward/backward motion of the output shaft into an opening/closing motion in the horizontal direction and transmits the opening/closing motion to the pair of holding claws,
- wherein, when the pair of holding claws are moved to be opened/closed in the horizontal direction, the holding claw having the V-shaped groove is moved more than the holding claw having the flat face.
