とする自動工具交換装置の工具把持機構。 The exchange arm 6 includes a roller shaft 14 that is movable perpendicularly to the arm rotation axis 3, is always biased in the direction of gripping the tool, and is unlocked when gripping the tool and when releasing the gripped tool to prevent the tool from falling off.
In an automatic tool changer such as a machining center, the cam follower 19 is pivotally supported by a pin 18 provided at right angles to the roller axis, and the cam follower 19 is provided in the changer body parallel to the rotating surface of the swing arm. The exchange arm includes an arcuate cam 20 that can engage with the cam follower at a position where the exchange arm swings to grip or release a tool, and the arcuate cam 20 engages with the cam follower when the swing arm swings from a standby position to just before gripping a tool. A tool gripping mechanism for an automatic tool changer, characterized in that the roller shaft is retracted to eliminate interference between the roller shaft and the tool when gripping the tool.
