The grating ruler (ruler) is fixed in the aluminum profile shell, and the installation end caps are respectively fixed on both ends of the shell to form a measuring body based on the grating. The reading head is composed of a four-split phase indicating grating, a light source board, a receiving board, a shaping (matching) board and a cable. ACCESSORIES You Will Get 1*Digital readout display1*Linear scale1*English manualAccessories: Scale cover, L connection bracket, scale cover etc. Digital Display The digital display is a precise grating measurement system, suitable for precise measurement of large range. Especially suitable for measurement, medical equipment, precision modern processing equipment. CNC machining centers, milling machines, grinding machines, automatic unloaders, sheet metal pressing and welding machines, robotics and automation technology, production process measurement machines, linear products, linear motors, linear guide positioning, etc. Grating Ruler Three ball bearings are installed on the side of the indicating grating seat, and the gap between the indicating grating and the grating is positioned by them. There are two roller bearings on the upper part of the indicator grid. When the read head moves relative to the grating, the indicating grating seat is always attached to the scribed surface and top of the grating, so that the light source and the receiving plates installed on both sides of the indicating grating serve as the light source and shutter moire receiver, respectively. The photoelectric signal is processed into displacement figures by the digital display box. This completes the measurement of the grating line displacement. In order to facilitate the processing of the digital display (box), in the sensor, the photoelectric signal of the moire fringes is also shaped (matched), and then input through the cable. Before and after work Sensors and digital indicators should be placed in a dry and temperature-friendly machine location. The outgoing cables should be fixed on the machine The sensor should not be disassembled arbitrarily during use The connecting nails should be fixed and not loose, so as not to lose precision. The instrument should be kept clean, if there is any sand and waste, wipe it off with soft paper Ruler installation Use M4 nails to install the scale on the mounting surface of the worktable, but it is not fixed, fix the dial indicator on the machine tool, and move the worktable (the scales move together). Use a dial indicator to measure the parallelism of the main ruler in the direction of movement of the guide rail, adjust the position of the M4 nail to the value of 0.1mm/1000mm, and fix the M2 nail. Used on machine tools Basic work of grating digital displacement sensor When a pair of grating scales are relatively displaced, black and white (or light and dark) moire fringes are generated under the action of light. The same black and white (or light and dark) stripes are converted into sine waves by optoelectronic devices. After amplification and shaping circuit, two sine waves with a difference of 90° are obtained, which are sent to the digital display. How to get started Install the ruler on the workbench, which can be installed in different parts. Moving with the milling machine tool, the reading head is fixed on the machine tool and installed below the scale as much as possible. Pay attention to the direction of splashing of chips, cutting fluid and oil. If it must be installed upwards, an auxiliary sealing device must be added. The reading head should be installed on the stationary part relative to the machine tool, the output wire should be fixed, and the scale should be installed on the relatively moving part (such as a slide plate).
