Patent ID: 7282017

Claim:
Tool-switching device, comprising: at least one removable tool-carrier; an adapter adapted for being fastened to a machine for measuring coordinates; positioning surfaces arranged on said tool-carrier and on said adapter defining a removable isostatic connection between said tool-carrier and said adapter; a first coupling means in said tool-carrier and a second coupling means in said adapter; one of said coupling means having an actuator, rotatable about an axis and having a camming portion that is eccentric relative to the rotation axis, and driving said first coupling means, said actuator being capable of taking a locked position and an unlocked position; said first and second coupling means locking said tool-carrier relatively to said adapter in a relative position defined by said isostatic connection when said actuator is in said locked position, wherein the force exerted during locking on said first and second coupling means is aligned to a longitudinal axis of said tool-carrier.
