Linear motor tell you what is the grating ruler, during the Spring Festival in the forum to see a lot of friends ask the grating ruler is what? What is the working principle of grating ruler? Grating function is what a series of problems, then Tongmao Xiaobian grating on this topic and talk to you.
Grating ruler, also known as a grating ruler displacement sensor or a grating ruler sensor, is a measurement feedback device that operates using the optical principle of a grating. The grating ruler is often used in closed-loop servo system of CNC machine tools, which can be used as linear displacement or angular displacement detection.
The measurement output signal is a digital pulse, with a large detection range, high detection accuracy, fast response. For example, it is commonly used in CNC machine tools to detect the coordinates of tools and workpieces to observe and track the cutting error, which can compensate for the motion error of the tool.
The grating ruler is composed of scale grating and grating read head two parts. Scale grating generally fixed on the moving parts of the machine, grating readhead mounted on the fixed part of the machine, indicating the grating mounted in the grating readhead. Raster detection device structure The key part of the grating detection device is the grating reading head, which consists of a light source, a convergent lens, an indication grating, a photoelectric element and an adjustment mechanism.
Grating readhead structure many forms, according to the readhead structure and characteristics of the use of occasions is divided into direct-receiving reading head.
Today Tongmao Xiao Bian and we introduced what is the grating ruler, as well as the composition and application of grating ruler, and then will continue to introduce the charm of the grating ruffle.
