Abstract

The invention relates to a ten-thousandth micrometer, which is a widely used mechanical measuring tool. One hundred ten-thousandth lines which are in parallel with the original datum line of a micrometer are added on a fixed sleeve of the ten-thousandth micrometer and the original datum line is named as a 0 ten-thousandth line. The former fifty ten-thousandth lines from 0 to 49 are short one-thousandth lines and the later fifty ten-thousandth lines from 50 to 100 are long ten-thousandth lines. Numerical values from 0, 5, 10 ellipsis 100 which are arranged in sequence are marked at one end of a ten-thousandth line at an interval of five long or short ten-thousandth lines. The width of every two adjacent long or short ten-thousandth lines is 1.01 times of the width of every two adjacent scales of a corresponding micro-drum. The minimum scale value of the ten-thousandth micrometer is one-hundredth of each scale value of the micro-drum and is 0.0001mm. A magnifying glass is additionally arranged on the micro-drum to more intuitively and clearly recognize and read the scale values of the ten-thousandth lines corresponding to the scales of the micro-drum. The ten-thousandth micrometer fills a market blank of mechanical measuring tools.

Description

Tenthousandth micrometer

Technical field tenthousandth micrometer of the present invention relates to a kind of mechanical measurement instrument of widespread use.

The milscale of the present widespread use of background technology, the scale value of most of minimums is 0.01 millimeter.On market, have a kind of micron of milscale, its little scale value is 0.001 millimeter.One key name of State Intellectual Property Office is also 0.001 millimeter the minimum scale value of patent (patent No. 201010592401.2) technology of " a kind of tenthousandth micrometer ", once mentions with eye estimate in its specification digest, can guess 0.0001 millimeter.For most technician, be difficult to 1 millimeter of following accurate numerical value of range estimation.Processing technology precision is more and more higher now, but also there is no to measure the mechanical measurement instrument of minimum 0.0001 millimeter of scale value.

It is 0.0001 millimeter that summary of the invention the object of this invention is to provide a kind of minimum scale value, and the mechanical measurement instrument of scale value is read in the clear accurate identification of energy.

Invention relates to fixed muffle and these two parts of microdrum of milscale, on fixed muffle, have a datum line, its two ends do not have numerical value, and it is the numerical value to microdrum high scale line for reading, its both sides also have perpendicular short scale mark, and indicate scale value.Tenthousandth micrometer also has above scale mark and scale value, but indicates this numerical value of 0 word in its datum line one side.On tenthousandth micrometer, it is defined as to line 0 line very much, this datum line to the minimum scale value on microdrum, be 0.01 millimeter.To line 0 line clockwise direction very much, it has also increased by 100 in parallel and every five scale marks and has just indicated 5,10,15 respectively ... the line very much of the scale values such as 100.Very much line from the length that indicates the scale mark of 50 numerical value and start it than from 0 to 49 line is very much a little long before this, object be with front 50 very much line distinguished, so this has also just produced long line and short line very much very much.Every two adjacent length very much the width value of line or short line be very much to every two adjacent scale mark width values on microdrum 1.01 times.Every two adjacent short long lines very much that have between line very much, also can be said to is that every two adjacent length have a short line very much very much between line.On the microdrum of tenthousandth micrometer, also increase a circular magnifier, in order to clear accurate identification, read microdrum scale mark and the corresponding scale value of line very much.

Due to every two the adjacent length of tenthousandth micrometer very much the width of line or short line be very much to every two adjacent scale marks on microdrum 1.01 times, when microdrum and the corresponding scale mark of line very much being moved forward to next institute to line very much, the scale value equaling on microdrum has moved forward again one of percentage, this is also the function place of tenthousandth micrometer, it can by the scale value (0.01 millimeter) on microdrum again differential become 100 parts.For can clear accurate identification microdrum scale mark and the corresponding scale value of line very much, specially on tenthousandth micrometer microdrum, have increased a magnifier.

Accompanying drawing explanation: the fixed muffle of tenthousandth micrometer of the present invention and microdrum schematic diagram are provided by the following drawings.

The long line very much of figure (1), figure (2) short line very much, figure (3) is magnifier, and figure (4) is fixed muffle, and figure (5) is microdrum scale mark, and figure (6) is microdrum, figure (7) is that datum line is also line 0 line very much.

The diameter of the fixed muffle of embodiment tenthousandth micrometer (4) and microdrum (5) is larger than conventional milscale, and using method is identical with milscale.100 very much lines parallel with former milscale datum line on its fixed muffle (4), have been increased, former datum line be defined as very much line 0 line every 5 very much one end of line also indicate respectively 0,5,10 in order ... numerical value to 100, from indicating line segment that the line very much of 50 numerical value starts it than length before this bit, from then on also produced long line (1) and short line very much (2) very much, also can by length wherein, line or short wire tag very much become redness very much.Every two adjacent length very much the width of line (1) or short line very much (2) be to every two the adjacent scale marks of microdrum (6) (5) width 1.01 times.The scale value of microdrum often moves forward lattice, the measuring distance moving is 0.01 millimeter, when moving forward to microdrum scale mark again and line is relative very much, measuring distance has moved again one of percentage of 0.01 millimeter, and this is 0.0001 millimeter of the minimum scale value of tenthousandth micrometer just also.Magnifier (3) on microdrum (6) is to set up for more visual and clear identification microdrum scale mark and the corresponding scale value of line very much.
