Description
Technical field
The utility model relates to a kind of grating scale, refers in particular in a kind of installation process the optical grating construction of the depth of parallelism being convenient to adjust grid stroke and the grating scale with dust reduction capability.
Background technology
There is glass raster the grating scale inside that present society uses as scale grating, in long use procedure, because glass raster is transparent material, glass raster can accumulate dust and be easy to occur scratching phenomenon, reduce its transmissivity, not only can affect the measuring accuracy of grating sensor, but also the risk of Lou number can be caused, this kind of grating scale generally has grid stroke and one group of zero locatino grating line of four groups of fixed skew on indication grating, in the process of installing, need the depth of parallelism regulating the light Gate line on indication grating and the light Gate line on glass raster, affect by part machining tolerance and production run, often can not leveling row very easily, if and parallel not, grating sensor measuring accuracy can be affected equally, but also the risk of leaking number can be there is, it uses inconvenience, practicality is poor.
Summary of the invention
In order to solve the problem, the utility model aims to provide a kind of grating scale, refers in particular in a kind of installation process the optical grating construction of the depth of parallelism being convenient to adjust grid stroke and the grating scale with dust reduction capability.
Realize above-mentioned purpose, the technical solution adopted in the utility model is: a kind of optical grating construction of grating scale, comprise slide rail and be slidably disposed on the testing agency on described slide rail, described testing agency is provided with glass key light grid and indication grating, described glass key light grid are provided with dustproof membrane, described indication grating are provided with the grid stroke group that several angles of inclination are different.
Wherein, described glass key light grid are fixedly installed in described slide rail by viscose; be arranged at the main grating surface of glass described dustproof membrane clad type; described dustproof membrane is Transparent Nano-Coatings; described nano coating comprises air barrier and grating protective seam, and described grating protective seam is arranged between described air barrier and described glass key light grid.
Wherein, described indication grating at least comprises the grid stroke group of two groups of differing tilt angles, and often organizing described grid stroke group has some the grid strokes at same angle of inclination to form respectively.
The beneficial effects of the utility model are presented as: the utility model aims to provide a kind of optical grating construction of grating scale, by arranging dustproof membrane on glass raster, make it avoid in long-time use procedure and to cause the precise decreasing of product because of the accumulation of dust and prevent scratching of grating, and that it changes the optical texture of traditional indication grating, make it have the pilot light grid line group of some groups of different angles, can easily grid stroke leveling row, its structure is simple, easy to use, practical.

Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing:
As Figure 1-4, a kind of optical grating construction of grating scale, the testing agency 2 comprising slide rail 1 and be slidably disposed on described slide rail 1, described testing agency 2 is provided with glass key light grid 3 and indication grating 4, described glass key light grid 3 are provided with dustproof membrane 5, described indication grating 4 are provided with the grid stroke group 6 that several angles of inclination are different.
Wherein, described glass key light grid 3 are fixedly installed in described slide rail 1 by viscose; be arranged at glass key light grid 3 surface described dustproof membrane 5 clad type; described dustproof membrane 5 is Transparent Nano-Coatings; described nano coating comprises air barrier 7 and grating protective seam 8, and described grating protective seam 8 is arranged between described air barrier 7 and described glass key light grid 3.
Wherein, described indication grating 4 at least comprises the grid stroke group 6 of two groups of differing tilt angles, often organizes described grid stroke group 6 and is made up of some the grid strokes at same angle of inclination respectively.
The utility model is coated with nano coating in traditional glass key light grid 3 outside, be divided into air barrier 7 and glassivation 8 particularly, it is made to be not easy in use meet accident scratch on the one hand, reduce its surface tackiness on the other hand, dust-proof being easier in its surface is dropped, thus ensure that glass key light grid 3 still can not affect its measuring accuracy after a long time use, avoid the generation of the Lou dangerous phenomenon such as number, secondly, indication grating 4 arranges the grid stroke group 6 of many group different angles, for the many groups of grid strokes be parallel to each other on traditional indication grating 4, being more convenient for, it is parallel to be regulated by grid stroke, only need on indication grating 4 any one group of grid stroke group 6 parallel with the grid stroke on scale grating, and grid stroke group 6 mismachining tolerance that more group of the grid stroke group 6 of many group different angles is parallel to each other is few, more effectively improve the measuring accuracy of grating scale, thus possess more outstanding measurement effect.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, the technician of the industry, under the inspiration of the technical program, some distortion and amendment can be made, every above embodiment is done according to technical spirit of the present utility model any amendment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
