Abstract
An alignment device has a support base attached to a conveying device, and a mounting plate to which a gripping member is attached, and the mounting plate is transferably abutted on a fastening holder that is fixed to the support base. A movable ring fixed to the mounting plate has a sliding part that is transferably engaged with the fastening holder. A first holding mechanism arranged between the fastening holder and the mounting plate locks the mounting plate to the fastening holder. A second holding mechanism provided between the fastening holder and the movable ring cancels a first-direction force of the mounting plate.
Claims10
An alignment device comprising:
- a support base having a cylinder hole for incorporating an axially transferable lock piston, the support base being attached to a conveying device;
- a mounting plate transferably abutted in a movable direction on a front surface of a fastening holder that is fixed to the support base, a gripping member being attached to the mounting plate;
- a movable ring provided with a sliding part that is transferably engaged with the fastening holder in the movable direction, the movable ring being fixed to the mounting plate;
- an axis conforming holder arranged between the fastening holder and the mounting plate, and having a first holding force that is driven by the lock piston and causes a reference axis of the mounting plate to conform with and lock a reference axis of the fastening holder;
- and
- a force canceling holder provided between the fastening holder and the movable ring, and having a second holding force that admits a state where the mounting plate is transferable in the movable direction and that cancels a first-direction force applied to the mounting plate, the first-direction force being a force in a direction of shifting the reference axis of the mounting plate from the reference axis of the fastening holder,
- wherein the force canceling holder is turned on and off by a fluid pressure actuating mechanism.
