Abstract
An optical transducer element in the form of a circular pulse raster disk or a pulse raster ruler mounted on a drive shaft, a tool carriage, a sliding stage, or a linearly movable position transducer has a peripheral edge running through a sensor gap of a transducer device for detecting at least one of a movement and a position. The optical transducer element is installed, centered and adjusted by: pre-positioning the optical transducer element in a preliminary position where the peripheral edge is located outside the sensor gap, and laterally sliding the optical transducer element into a centered fine-adjustment position where the peripheral edge reaches into said sensor gap.
Claims10
A method for positioning an optical transducer element comprising one of a circular pulse raster disk and a pulse raster ruler on a supporting element comprising one of a drive shaft, a tool carriage, a sliding stages, and a linearly movable position transducer, wherein the optical transducer element has a peripheral edge running through a sensor gap of a transducer device for detecting at least one of a movement and a position, the method comprising the steps of:
- pre-positioning the optical transducer element in a preliminary position where said peripheral edge is located outside said sensor gap, and
- laterally sliding the optical transducer element into a centered fine-adjustment position where said peripheral edge reaches into said sensor gap.
An optical transducer element with an opening adapted for fastening the optical transducer element onto a supporting element comprising one of a drive shaft, a tool carriage, a sliding stage, and linearly movable position transducer, wherein the optical transducer element has a peripheral edge running through a sensor gap of a transducer device for detecting at least one of movement and a position, and wherein said opening has a pre-positioning part and a centered adjustment part located at a distance from each other that is at least equal to an entry depth of said peripheral edge into said sensor gap.
