Abstract
The utility model discloses a high precision screw micrometer for measuring objects, relating to a measuring tool. The high precision screw micrometer comprises a scale rack, a measuring anvil, a main scale, a fixed sleeve barrel, a differential sleeve barrel, a fine adjustment screw and a standard vernier. The unit graduation on the standard vernier has an error compared with that on the differential sleeve barrel. The sum of the ten unit graduations on the standard vernier and the sum of the nine unit graduations on the differential sleeve barrel are in the same value.
Description
A kind ofly be used for the high-precision spiral micrometer that object is measured, especially comprise the screw-thread micrometer of accurate vernier, relate to metering equipment.
The metering equipment that is used for Measuring Object length now mainly contains ruler, vernier scale and screw-thread micrometer.The ruler measuring accuracy is the millimeter level, and make measuring accuracy then is being inaccessible more than 0.1 millimeter; The vernier scale precision is 0.1 millimeter, measuring accuracy then inapplicable more than 0.01 millimeter; Screw-thread micrometer is that measuring accuracy is the highest in above-mentioned three kinds of metering equipments, its precision has reached 0.01 millimeter, and present required object measuring accuracy often occurs 0.001 millimeter, so, existing metering equipment then can not be suitable for, and often causes defectives such as part is defective because of estimated error.Therefore, existing quantitative change degree device exists shortcomings such as measuring accuracy is low.
Goal of the invention of the present utility model is at above-mentioned deficiency, designs and propose a kind of high-precision spiral micrometer.
The utility model is made up of chi frame, gage button, main scale, fixed muffle, differential sleeve, the little spiral of accent, its invention main points are to set up vernier surely on fixed muffle, and unit scale set on this accurate vernier has been compared an error with the unit scale on the differential sleeve.The utility model is set ten unit scale sums on the accurate vernier and nine unit scale sums on the differential sleeve for equivalence.
Compared with prior art,, make the precision of screw-thread micrometer bring up to 0.001 millimeter level by 0.01 millimeter original level because the utility model is set up vernier surely on fixed muffle, so, the utlity model has advantage of high precision.In addition, on the accurate vernier the special setting of unit scale make again the utlity model has easy to use, the simple advantage of reading.In sum, the utlity model has the precision height, advantage easy to use.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is the utility model scale part stretch-out view, and 0,5,10,45 for demarcating numeral shown in the figure.
Contrast accompanying drawing below, describe an embodiment of the present utility model in detail:
The utility model by chi frame (1), gage button (2), main scale (3), snap close (4), fixed muffle (5), differential sleeve (6), transfer little spiral (7) and accurate vernier (8) to form, it is other that accurate vernier (8) is located at the master calibration (9) of fixed muffle (5), goes up set ten unit scale sums and last nine the set unit scale sum equivalences of differential sleeve (6) at accurate vernier (8).In use, its number reading method is the comprehensive number reading method that adopts existing screw-thread micrometer and vernier scale, accurate vernier (8) is that with the difference of the vernier scale that uses now the relative chi frame of accurate vernier of the present utility model maintains static, and the relative chi frame of the vernier on the vernier scale slides.
Claims (2)
1, a kind of high-precision spiral micrometer that is used for the object measurement, form by chi frame, gage button, main scale, fixed muffle, differential sleeve, the little spiral of accent, it is characterized in that being provided with on fixed muffle vernier surely, unit scale set on this accurate vernier has been compared a difference with the unit scale of differential sleeve.
2, high-precision spiral micrometer according to claim 1 is characterized in that nine set unit scale sum equivalences on set ten unit scale sums and differential sleeve on the accurate vernier.
