Description
Technical field
The present invention relates to measurement instrument, relate in particular to and a kind of milscale is carried out improved tenthousandth micrometer.
Background technology
At present the milscale that uses is to make according to the principle that spiral amplifies, and promptly screw rod rotates a circle in nut, and screw rod just advances or the distance of a slow astern pitch along the rotation direction.Therefore, along the slight distance that axis direction moves, just can come out with the readings signify on the circumference.Therefore the pitch of the accurate thread of micrometer caliper is 0.5mm, and movable mark has 50 evenly divideds, and movable mark rotates a circle, and micrometric screw can advance or retreat 0.5mm, rotates each little calibration, is equivalent to micrometric screw and advances or postpone 0.5/50=0.01mm.As seen, each little calibration of movable mark is represented 0.01mm, so micrometer caliper can be accurate to 0.01mm.Owing to can also estimate again and read one, can read thousand fens positions of millimeter, so the name milscale.But along with the continuous development people of industrial technology are more and more higher to the precision requirement of measuring appliance, milscale can not satisfy the needs of measuring accuracy in a lot of fields, a lot of fields need be accurate to degree of accuracy position very much, so, people just need a kind of tenthousandth micrometer, but, the measuring appliance price that degree of accuracy can be accurate at present position very much on the market is generally high, if we can improve milscale self, further increase the degree of accuracy of milscale, so just can solve the expensive problem of tenthousandth micrometer, simultaneously, also do not abandoned milscale and saved resource.
Summary of the invention
The present invention is directed to the deficiency of above-mentioned technical matters, aim to provide a kind of improved tenthousandth micrometer that on the basis of milscale, carries out, promptly above the horizontal line of milscale, add the 0.9 outer sleeve scale unit of carving 10 five equilibriums, in reading, read after integer-bit, tenths and the hundredths,, read thousand fens positions by 0.9 unit scale of these 10 five equilibriums, estimate again and read conduct position very much, so just simply milscale has been become measuring accuracy tenthousandth micrometer more accurately
The present invention is achieved through the following technical solutions: a kind of tenthousandth micrometer, comprise arc support, one end of support is provided with gage button by the gage button sleeve, the other end of support is connected with micrometric screw by the micrometric screw locking device, described micrometric screw arranged outside has digital display device, described digital display device comprises and is arranged on fixed muffle that the micrometric screw outside cooperates with micrometric screw and the quill that is linked in the fixed muffle outside surface, described fixed muffle is provided with the master calibration card, described quill is provided with lattice scale card, and the scale mark on the described lattice scale card is that the quill periphery is divided into 50 lattices; The master calibration card of described fixed muffle comprises a horizontal line, described horizontal line is parallel to described micrometric screw, the horizontal line below is marked with the master calibration mark, described master calibration mark comprises zero graduation mark, millimeter scale mark and 0.5 millimeter scale mark that each millimeter scale mark is divided equally, the vertical and described horizontal line of described zero graduation mark; Described horizontal line top also is provided with thousand fens position scale marks, the position scale mark had 10 little evenly divideds as the zero graduation mark to the above bearing mark of master calibration card with described horizontal line in described thousand minutes, described 10 little evenly divided length overalls are 9 units of quill scale, and every equal portions are 0.9 unit of quill scale.
Below above technical scheme is further elaborated:
Described master calibration is marked with the millimeter scale mark of 25 five equilibriums, 25 millimeters of described 25 millimeter scale mark length overalls, and each millimeter scale mark is 1 millimeter.
Beneficial effect of the present invention is: one, because milscale and vernier caliper all are to measure after the testee clamping, the present invention is combined on the milscale further the accurately reading of milscale with vernier caliper, the present invention is arranged on the horizontal line below with original master calibration mark on the milscale fixed muffle, above the horizontal line of milscale fixed muffle, be marked with 10 little evenly divideds, 10 little evenly divided length overalls are 9 quill units, and each calibration is 0.9 quill unit; Because to read be 0.01 millimeter to each lattice of quill on the milscale, if the place calibrated dial aligns with quill lattice scale, then reading is 0.1x0.01=0.001, is about to reading and is accurate to thousand fens positions, estimates to read one and be very much again; Two, the present invention is simple in structure, and is convenient and practical.
