Generally, the Dongguan grating ruler is installed on the worktable of the machine tool, moving randomly with the cutting of the bed. The reading head is fixed on the bed, and the reading head is installed below the main ruler as much as possible. The selection of its installation method must pay attention to the splashing direction of chips, cutting fluid, and oil. If it is necessary to install with the reading head facing upwards due to installation location limitations, an auxiliary sealing device must be added.

Dongguan grating ruler installation guide:

1. Dongguan grating ruler displacement sensor installation base

When installing the Dongguan grating ruler sensor, it is not allowed to directly install the sensor on rough and uneven machine tools, let alone on machine tools with primer coating. The grating ruler and reading head are installed on two components of the machine tool that move relative to each other. Use a micrometer to check the parallelism between the installation surface of the main ruler of the machine tool worktable and the direction of the guide rail movement. The micrometer is fixed on the bed and the worktable is moved to achieve parallelism within 0.1mm/1000mm. If this requirement cannot be met, a Dongguan grating ruler base needs to be designed and processed.

2. Installation of Dongguan grating ruler displacement sensor main ruler

Use M4 screws to attach the grating ruler to the mounting surface of the worktable on the machine tool, but do not tighten it tightly. Fix the micrometer on the bed and move the worktable. Measure the parallelism between the main ruler plane and the machine tool guide rail movement direction with a dial gauge, adjust the position of the M4 screw on the main ruler to ensure that the parallelism of the main ruler is within 0.1mm/1000mm, and then tighten the M2 screw thoroughly.

3. Installation of Dongguan Grating Linear Displacement Sensor Reading Head

When installing the reading head, first ensure that the base surface of the reading head meets the installation requirements, and then install the reading head. The installation method is similar to that of the main ruler. Finally, adjust the reading head to ensure that the parallelism between the reading head and the main ruler of the grating is within 0.1mm, and the gap between the reading head and the main ruler is controlled within 1~1.5mm.

4. Dongguan grating ruler displacement sensor limit device

After installing all the grating line displacement sensors, it is necessary to install a limit device on the machine tool guide rail to prevent the reading head from colliding with the two ends of the main ruler when the machine tool processes the product and damaging the Dongguan grating ruler. In addition, when purchasing a grating line displacement sensor, users should try to choose a Dongguan grating ruler that exceeds the machine tool processing size by about 100mm to leave room for error.

5. Dongguan grating ruler displacement sensor inspection

After the installation of the grating line displacement sensor is completed, the digital display meter can be connected, the workbench can be moved, and the counting of the digital display meter can be observed to see if it is normal.
