Abstract
The utility model discloses a micron meter which comprises a micrometer; 11 axial graduation marks are arranged on a fixed sleeve along the circumference; and the distance between two graduation marks is 9/10 of the smallest scale mark on the microdrum. A semi-millimeter graduation mark is arranged on the upper edge of the graduation mark marked as 10 on the fixed sleeve; an entire-millimeter graduation mark is arranged on the lower edge of the graduation mark marked as 0 on the fixed sleeve. Among the 11 axial graduation marks, the graduation mark marked as 0, the graduation mark marked as 5 and the graduation mark marked as 10 are longer than the rest graduation marks. The micron meter can accurately and uniquely confirm the estimated value on the thousands of the original micrometer by additionally arranging 11 graduation marks on the fixed sleeve; therefore, the precision of the micron meter can reach 1 micron, namely 0.001mm.
Description
Technical field
The utility model relates to a kind of measuring appliance, and particularly a kind of measuring accuracy is the micron chi of 0.001mm.
Background technology
At present at the milscale that uses, measuring accuracy is 0.01mm, and more accurate numerical value can only be estimated and reads.
Summary of the invention
The purpose of this utility model is that a kind of micron chi will be provided, and the measuring accuracy that it can reach is 0.001mm.
The purpose of this utility model is achieved in that a kind of micron chi, comprises milscale, and fixed muffle upper edge circumference is provided with 11 axial scale marks, between two scale marks spacing be on the microdrum minimum calibration 9/10.Half millimeter scale mark is located at the upper edge that is labeled as 10 scale mark on the fixed muffle, and whole millimeter scale mark is located at the lower edge that is labeled as 0 scale mark on the fixed muffle.Article 11, in the axial scale mark, wherein be labeled as 0 scale mark, be labeled as 5 scale mark and be labeled as 10 scale mark and be longer than other scale mark.
The micron chi that the utility model provides by 11 scale marks are set, can will be estimated accurate and unique the deciding of reading value on thousand fens positions of former milscale on fixed muffle, so its degree of accuracy has reached 1 micron, i.e. and 0.001mm.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model one-piece construction synoptic diagram.
Numerical value read synoptic diagram when Fig. 2 was the utility model use.
Embodiment
A kind of micron chi comprises milscale 1, and fixed muffle 2 upper edge circumference are provided with 11 axial scale marks, between two scale marks spacing be on the microdrum 3 minimum calibration 9/10.Half millimeter scale mark is located at the upper edge that is labeled as 10 scale mark on the fixed muffle 2, and whole millimeter scale mark is located at the lower edge that is labeled as 0 scale mark on the fixed muffle 2.Article 11, in the axial scale mark, wherein be labeled as 0 scale mark, be labeled as 5 scale mark and be labeled as 10 scale mark and be longer than other scale mark.
During use, the microdrum 3 mobile in the axial direction 0.5mm of micrometric screw 4 that rotates a circle.Microdrum 3 is divided into 50 little lattice, and every little lattice are: 0.5/50=0.01mm.If minimum scale division is from being a on the microdrum 3, then microdrum 3 turns over the distance of a minimum calibration a, and micrometric screw 4 displacement in the axial direction is 0.01mm.11 ruling spans are from being 9/10a on the fixed muffle 2, and then microdrum turns over the distance of 9/10a, and micrometric screw 4 displacement in the axial direction is 0.009mm.As find that x bar groove in these 11 grooves on the fixed muffle 2 aligns with y scale on the microdrum 3 when measuring reading behind the object, then numerical value reads and should be, whole millimeter and half millimeter read from fixed muffle 2, should be tried to achieve by calculating formula (0.01y-0.009x) less than the numerical value of 0.5mm.Be similar to vernier caliper, also reading numerical values like this, earlier the whole millimeter on the fixed muffle 2 is read in the position that is labeled as 0 scale mark from the fixed muffle 2, be labeled as 10 scale mark position and read half millimeter, the numeral (do not estimate and read) of adding on this microdrum 3 that is labeled as 0 scale mark position correspondence multiply by 0.01mm, adds then on the fixed muffle 2 that the scale mark number that aligns with scale on the microdrum 3 multiply by 0.001mm.
Should be read as 8.946mm as the measurement numerical value among Fig. 2.Promptly reading whole millimeter from fixed muffle 2 is 8.5mm with half millimeter.From being labeled as the numerical value that 0 scale mark position reads on the corresponding microdrum 3 is 44*0.01=0.44mm, reading the groove numerical value that aligns with microdrum 3 high scales from fixed muffle 2 is 6*0.001=0.006mm, and the read value of three parts is added up to 8.5+0.44+0.006=8.946mm.
