Novel grating ruler protection structure

Abstract

The utility model relates to a novel grating ruler protection structure. Comprising a lathe bed, a workbench arranged on the lathe bed, a sliding block sliding on the workbench, a driving part driving the sliding block to move, a read-write head arranged on the workbench, a grating ruler arranged on the sliding block, a first shielding part for shielding cutting fluid and a second shielding part for shielding the cutting fluid. Two groups of first shielding pieces are oppositely arranged; one ends of the two first shielding pieces correspond to the two sides of the sliding block, and the other ends of the two first shielding pieces correspond to the two ends of the workbench correspondingly. The second shielding piece corresponds to the grating ruler; the second shielding piece is arranged on the side wall of the sliding block; the read-write head corresponds to the grating ruler; the driving part is arranged on the workbench; the acting end of the driving piece corresponds to the sliding block.

[0002] In the prior art, with the development trend of numerical control machine tool technology, the processing accuracy requirements of domestic numerical control machine tools are getting higher and higher, and they begin to catch up with foreign counterparts. This requires the introduction of foreign grating scale technology to assist in detecting the processing accuracy of machine tools, so that grating scales need to be installed on the machine tools. Since the processing environment of horizontal machine tools is harsh (such as cutting fluid pollution), grating scales are usually not installed (if the installation protection is not in place, the grating scales are likely to be burned out), which poses high requirements for the installation and protection of the installed grating scales. The correct installation of the protection of the grating scale directly determines its service life and installation and use accuracy. Summary of the Utility Model
