Description
Technical field
The utility model relates to a kind of grating scale, refers in particular to a kind of glass key light grid that adopt and replaces aluminium section bar slide rail as the governor motion of the grating scale of measuring basis.
Background technology
Along with the development of scientific and technological industry, the precision requirement of electronic component improves constantly, in order to ensure precision in process of production, grating scale is widely used as precision survey instrument, the current grating scale used on the market, at grating displacement sensor in the process of installing, all install as reference field with the surface of aluminium section bar slide rail, because aluminium section bar slide rail is metal material, its machining tolerance is larger, therefore the alignment error of grating displacement sensor can be caused large when it is installed as reference field, affect the measuring accuracy of grating displacement sensor, cause unnecessary impact in process of production, it uses inconvenience, poor practicability.
Summary of the invention
In order to solve the problem, the utility model aims to provide a kind of grating scale, refers in particular to a kind of glass key light grid that adopt and replaces aluminium section bar slide rail as the governor motion of the grating scale of measuring basis.
Realize above-mentioned purpose, the technical solution adopted in the utility model is: a kind of governor motion of grating scale, comprise slide rail, be slidably mounted in the testing agency on described slide rail and be fixedly installed on the glass key light grid in described slide rail, described slide rail two side is along its length provided with several side openings all accordingly, described slide rail is provided with mounting groove, described glass key light grid are fixedly installed in described mounting groove by viscose, and described glass key light grid are etched with Measurement scales line.
Wherein, described side opening and described Measurement scales line are arranged on sustained height accordingly, are removably provided with dust plug in described side opening.
Wherein, described glass key light grid are flatly provided with lug boss and depressed part respectively, and the edge of described lug boss and described depressed part forms the described Measurement scales line of level mutually.
Wherein, described dust plug is transparent plug, and the section radius of described plug is greater than described side opening section radius, and described side opening spacing is greater than the entire length of testing agency, makes described side opening can observe scale mark on described glass key light grid simultaneously.
The beneficial effects of the utility model are presented as: the utility model aims to provide a kind of governor motion of grating scale, by arranging side opening in the side of aluminium section bar slide rail, and be on glass key light grid in side opening corresponding height and etch clock gauge, with glass key light grid substitution of Al section bar slide rail as measurement datum, after mixing up position, plug is filled in the side opening of aluminium section bar to prevent pollutant from entering grating sensor inside, because the machining precision of glass main grid ratio aluminium section bar slide rail is high, directly on glass surface, play table reduces Abbe error, thus improve the installation accuracy of grating sensor, 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 1-3, a kind of governor motion of grating scale, comprise slide rail 1, be slidably mounted in the testing agency 2 on described slide rail 1 and be fixedly installed on the glass key light grid 3 in described slide rail 1, described slide rail 1 two side is along its length provided with several side openings 4 all accordingly, described slide rail 1 is provided with mounting groove 5, described glass key light grid 3 are fixedly installed in described mounting groove 5 by viscose, and described glass key light grid 3 are etched with Measurement scales line.
Wherein, described side opening 4 is arranged on sustained height accordingly with described Measurement scales line, is removably provided with dust plug 7 in described side opening 4.
Wherein, described glass key light grid 3 are flatly provided with lug boss 8 and depressed part 9 respectively, and the edge of described lug boss 8 and described depressed part 9 forms the described Measurement scales line of level mutually.
Wherein, described dust plug 7 is transparent plug, and the section radius of described plug is greater than described side opening 4 section radius, and described side opening 4 spacing is greater than the entire length of testing agency 2, makes described side opening 4 can observe scale mark on described glass key light grid 3 simultaneously.
The utility model is flatly provided with lug boss 8 and depressed part 9 by directly arranging on glass key light grid 3, and jointly form clock gauge by the edge line of lug boss 8 and depressed part 9, substitute traditional aluminium section bar slide rail 1 using glass key light grid 3 to install as measuring basis, coordinate the side opening 4 that the two side of aluminium section bar slide rail 1 is arranged to carry out overall installation accuracy to regulate, observed by the Measurement scales line on side opening 4 pairs of glass key light grid 3, it is made to reach the installation accuracy of expection, the mismachining tolerance of glass key light grid 3 is utilized to be less than this characteristic of mismachining tolerance of aluminium section bar slide rail 1, directly effectively improve the installation progress of grating scale entirety, and after measurement completes in side opening 4 dust plug 7 beyond the Great Wall, pollutant is effectively avoided to enter grating sensor inside.
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.
