Tool carrier for an automatic tool changer
View Patent ↗The present disclosure relates to a tool carrier for an automatic tool changer. A tool carrier for an automatic tool changer according to the present disclosure includes: a base plate at which a center shaft is installed; a carrier unit installed at the center shaft to turn around the center shaft; a rotating pocket unit installed at the carrier unit to rotate and having a pin installed to protrude outward; a first cam block installed at the base plate and configured to perform a cam action with the pin to allow the pocket unit to rotate when the carrier unit turns from an initial position to the target position; and a second cam block installed at the base plate and configured to perform a cam action with the pin to allow the pocket unit to rotate when the carrier unit turns from the target position to the initial position.
1. A tool carrier for an automatic tool changer, comprising:
a base plate at which a center shaft is installed;
a carrier unit installed at the center shaft to turn around the center shaft;
a rotating pocket unit installed at the carrier unit to rotate and having a pin installed to protrude outward;
a first cam block installed at the base plate and configured to perform a cam action with the pin to allow the pocket unit to rotate when the carrier unit turns from an initial position to a target position; and
a second cam block installed at the base plate and configured to perform a cam action with the pin to allow the pocket unit to rotate when the carrier unit turns from the target position to the initial position.
2. The tool carrier for an automatic tool changer of claim 1 , wherein
the first and second cam blocks include:
first and second preceding sections configured to allow a rotating velocity of the pocket unit to uniformly decrease when the cam actions with the pin are performed;
first and second following sections configured to allow the rotating velocity of the pocket unit to uniformly increase when the cam actions with the pin are performed; and
first and second middle sections disposed between the first and second preceding sections and the first and second following sections to allow the rotating velocity of the pocket unit to be uniform.
3. The tool carrier for an automatic tool changer of claim 2 , wherein the first and second preceding sections and the first and second following sections have a linear shape, and the first and second middle sections have a curved shape.
