Abstract: A sensor adjustment mechanism for a coordinate measuring machine includes a sensor, first and second joints, a change interface, and a fixing device. The first joint allows the sensor to pivot about a first axis. The second joint allows the sensor to rotate about a second axis. The change interface releasably couples the sensor adjustment mechanism to a measuring head of the coordinate measuring machine. The fixing device is configured to clamp the joints. The change interface includes a first component and a ferromagnetic second component movable relative to the first component. The change interface is configured to be fixed to the measuring head by a magnetic fixing force exerted on the second component, which causes a movement of the second component relative to the first component. The movement actuates the fixing device so as to clamp the joints and inhibit the sensor from being pivotable and rotatable.
