Abstract
The utility model discloses a measuring apparatu error measuring grid board, the package rubbing board body and the net of printing at plate surface, net center of a lattice and plate body center coincidence, square size in the net is 1010mm, and the groove of square marks to - 17~17mm, the plate body adopts the quartz to make, and its thickness is 5.0mm, and the edge of plate body adopts atomizing and chamfer to handle, the utility model discloses a measuring apparatu error measuring grid board has solved the problem that jumbo size image measuring instrument two dimension dimension error can't once realize, makes the detection convenient, accurate more, accords with the normal requirement of the relevant calibration of country simultaneously.
Description
Technical field
This utility model relates to two-dimensional standard, for the measurement of the plane inside dimension error of the detecting instruments such as image measurer, particularly to a kind of measuring instrument error measure waffle slab.
Background technology
Present situation: along with the size of the detecting instruments such as image measurer is done bigger and bigger, original waffle slab size and precision can not meet far away the demand of equipment Inspection, original waffle slab is the sub-fraction in the comprehensive model of image measurer, and overall dimension is 20mm, grid about precision 1.5um. Glass linear scale can be used when generally detecting high-precision size, and linear scale belongs to one-dimensional standard, can only detect the scale error in a direction. Two-dimensional for image measurer has no way of measuring.
Summary of the invention
In order to overcome drawbacks described above, this utility model provides large scale, high-precision a kind of measuring instrument error measure waffle slab.
This utility model be the technical scheme is that a kind of measuring instrument error measure waffle slab to solve its technical problem, including plate body and the grid being printed on plate body surface, described net center of a lattice and plate body center superposition, grid size in described grid is 10*10mm, the groove of grid is denoted as-17��17mm, described plate body adopts quartz to make, and its thickness is 5.0mm, and the edge of plate body adopts atomization and chamfered.
As further improvement of the utility model, the width of described groove is 4um.
As further improvement of the utility model, the graduating accuracy of described grid is �� 0.5um.
The beneficial effects of the utility model are: measuring instrument error measure waffle slab of the present utility model solves the problem that large scale image measurer two-dimensional error cannot once realize, make detection convenient, accurate, meet the requirement of country's dependent correction specification simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation;
Figure indicates: 1-plate body; 2-grid.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment is only used for explaining this utility model, is not intended that the restriction to this utility model protection domain.
Fig. 1 illustrates a kind of embodiment of this utility model a kind of measuring instrument error measure waffle slab, including plate body 1 and the grid 2 being printed on plate body surface, the center of described grid 2 and plate body center superposition, grid size in described grid 2 is 10*10mm, and the groove of grid is denoted as-17��17mm, and described plate body 1 adopts quartz to make, its thickness is 5.0mm, the edge of plate body 1 adopts atomization and chamfered, and the line width of grid 2 medium square is 4um, and the precision of described grid is �� 0.5um.
The use procedure of waffle slab or related attentional problem:
1, wear glove to use;
Angle and location is noted when 2, putting;
3, its quartz plate of periodic monitoring and grid accuracy variable.
