Description

Technical Field

[0001] The utility model relates to the technical field of grating rulers, in particular to a grating ruler installation mechanism. Background Art

[0002] Grating ruler, also known as grating ruler displacement sensor, is a measurement feedback device that works on the optical principle of grating. Grating ruler is often used in the closed-loop servo system of CNC machine tools, and can be used to detect linear displacement or angular displacement. Its measurement output signal is a digital pulse, which has the characteristics of large detection range, high detection accuracy and fast response speed. For example, it is often used in CNC machine tools to detect the coordinates of tools and workpieces to observe and track tool feeding errors, so as to play a role in compensating tool motion errors. The grating main scale is used as the basic reference for data measurement. During the assembly process of the grating ruler displacement sensor, the grating main scale needs to be installed in place.
