Abstract
The utility model discloses a high-precision micrometer caliper. Aimed at providing a high-precision micrometer caliper with higher measuring precision, the utility model adopts the technical scheme that the high-precision micrometer caliper comprises a micrometer caliper; a bracket is fixedly mounted on the fixed graduated scale of the micrometer caliper; the bracket is fixedly connected with a vernier snap ring; the vernier snap ring is sleeved on a rotary scale ring; a zero mark area is formed on the vernier snap ring; the unit length of the zero mark area is one fiftieth of the circumference of the vernier snap ring; and the other part of the vernier snap ring is equally divided into 50 shares. The high-precision micrometer caliper has the advantages of simple structure, and improvement in measuring precision, and meets the requirements to high-precision micro-distance measurement of objects.
Description
Technical field:
The utility model relates to the microspur measurement mechanism, particularly a kind of high-precision spiral mircrometer gauge.
Background technology:
Present general employed micrometer caliper, the precision that can measure is 0.01 millimeter, and can not realize that for the measurement that higher accuracy requirement is arranged so just can not satisfy has higher microspur Testing requirement to object, if the use miscellaneous equipment, then the use cost of equipment is higher.
Summary of the invention:
The purpose of this utility model provides the higher high-precision spiral mircrometer gauge of a kind of measuring accuracy.The technical solution of the utility model is, a kind of high-precision spiral mircrometer gauge, it comprises micrometer caliper, it is characterized in that: be installed with support on the fixedly rule of micrometer caliper, support is fixedlyed connected with the vernier snap ring, and the vernier snap ring is sleeved on and rotates on the calibration loop.Described vernier snap ring be provided with 0 the degree position, 0 the degree position unit length be the vernier snap ring girth 1/50th, other parts with the vernier snap ring all are divided into 50 parts again.Of the present utility model simple in structure, the precision of measuring can be improved, satisfy the needs that object had high-precision microspur measurement requirement.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
Describe embodiment in conjunction with the accompanying drawings in detail, specific embodiment of the utility model is, a kind of high-precision spiral mircrometer gauge, it comprises micrometer caliper 1, on the fixedly rule 2 of micrometer caliper, be installed with support 3, support is fixedlyed connected with vernier snap ring 5, and the vernier snap ring is sleeved on and rotates on the calibration loop 4.The unit length that described vernier snap ring is provided with degree positions, 0 degree position 7,0 be the vernier snap ring girth 1/50th, other parts with the vernier snap ring all are divided into 50 parts again, per five parts is a district, sign has 1-10, totally ten positions.Using method of the present utility model is, close with the basic mode of using micrometer caliper, in original state of the present utility model be, fixedly 6 pairs of the up lines of 0 bit line of the medium line of rule and rotation calibration loop and 0 degree position on the vernier snap ring are straight, when using the utility model in the end to carry out reading, fixedly rule is read with the numerical value that rotates on the calibration loop earlier, see that again the line that rotates on the calibration loop is relative with which root line on the vernier snap ring, directly read district's value of that root line correspondence on the vernier snap ring, if line or 0 district in 10 districts on the line on the rotation calibration loop and the vernier snap ring are corresponding, then the reading value of vernier snap ring is 0, the numerical value of last Measuring Object is: fixing district's number * 0.001 on reading * 0.01 on the reading of rule * 0.5 millimeter+rotation calibration loop millimeter+vernier snap ring millimeter, be the last reading of testee, the utility model can improve ten times with the measuring accuracy of testee.
Claims (2)
