Abstract

This mechanism enables a machine, such as a robot, to change a drill automatically when broken or dull, or a different size drill is required. The replacement drills 10 are stacked in the rack 12. The robot (not shown) moves the drill motor 14 with modified quick change collet 16 attached, over the waiting docking space it wishes to place the used drill 10 in. The Z arm of the robot lowers the collet adapter 16 to a position where the two pins 18 can be oriented into the mating slots 20 in the hole 22, the collet passes through the hole 22 to an adapter 16 position beneath the hole, the collet adapter 16 rotates so the pins 18 no longer align with the slots 20, the Z motor then raises the drill motor 14, and this spreading action releases the drill 10 from the collet 16.

Automatic Drill Changer

This mechanism enables a machine, such as a robot, to change a drill automatically when broken or dull, or a different size drill is required. The replacement drills 10 are stacked in the rack 12. The robot (not shown) moves the drill motor 14 with modified quick change collet 16 attached, over the waiting docking space it wishes to place the used drill 10 in. The Z arm of the robot lowers the collet adapter 16 to a position where the two pins 18 can be oriented into the mating slots 20 in the hole 22, the collet passes through the hole 22 to an adapter 16 position beneath the hole, the collet adapter 16 rotates so the pins 18 no longer align with the slots 20, the Z motor then raises the drill motor 14, and this spreading action releases the drill 10 from the collet 16. The Z arm lowers, the slots 20 are realigned, and the collet and adapter 16 are removed from the hole 22. The robot then proceeds to the next position, aligns the pins 18 with the slots 20, passes through the hole 22, and the collet adapter 16 rotates so the pins 18 no longer align with the slots 20. The rack is now raised, and a new drill inserted. The Z arm is lowered, the pins 18 realigned, and the collet adapter 16 removed from the hole 22, at which time the robot can return to drilling holes with the new drill.
