Coordinate measuring instrument for determining spatial coordinates of a measurement object, as well as probe head for such a coordinate measuring machine

摘要

Coordinate measuring machine (10) for determining spatial coordinates of a measurement object (30), with a probe head sensor system (53) probe head (26) having a torso portion (38) and a relative to the torso portion (38) movable coupling part (40) has, on which a sensing device (27) is arranged, as well as a frame structure (14), which is designed, the probe head (26) relative to the measurement object (30) to a method, wherein the sensing device (27) at least one tracer pin (28) for scanning the object under test (30) and a turntable (74), via which the tracer pin (28) in one of a number of possible rotary angle positions of the coupling part (40) is coupled, further comprising a on the coupling part (40) is arranged displaceably pin (57), at which the sensing device (27) is fastened, and a on the torso portion (38) arranged stop (62), by which the pin (57) for a movement relative to the coupling part (40) can be fixed, wherein on the torso portion (38) at least one rolling projection (68) is formed on which the rotary plate (74) by means of a movement..
