Sensor element for a measuring machine, in particular a coordinate measuring machine

摘要

The invention relates to a sensor element for a measuring machine, having a sensing component with a sensing element for optically measuring a surface; a sensing element receiving portion with a plate-shaped base; and a sensor housing with a sensing component receiving portion comprising at least one bearing which contacts the base, which has at least one defined bearing point, and via which the sensing component is connected in a movable manner relative to the sensing component receiving portion. The sensor housing has a coupling on a housing coupling side for connecting to the measuring machine and at least partly surrounds the sensing component at the base, and a force directed in the direction of the sensing element is applied to the base. The sensing component receiving portion lies in the sensor housing opposite the coupling side and has the at a least one bearing.

1. A sensor element for a measuring machine, comprising:
a probe component having a probe element for optical measurement of a surface and a probe element holder with a plate-shaped base, a sensor housing with a probe component holder comprising at least one bearing which contacts the base and has at least one defined contact point by means of which the probe component is connected movably relative to the probe component holder, wherein the sensor housing has a coupling side with a coupling for a releasable connection, with the measuring machine, and optical contacts and/or electrical contacts, wherein the sensor housing at least partially encloses the probe component on the base and a force directed in the direction of the probe element is applied to the base, wherein the probe component holder lies opposite the coupling side in the sensor housing and carries the at least one bearing; and wherein the base of the probe component is arranged between the coupling side and the probe component holder, wherein a centrally arranged cylindrical or spindle-shaped compression spring, which presses the base against the at least one bearing and comprises an optical fiber guided in its longitudinal axis, is arranged between the coupling side and the base of the probe component.
