Abstract
The invention discloses a vernier caliper with a 0.02mm division value. The vernier caliper comprises a main scale and a vernier scale. The vernier scale has 50 indexing. The length of the each indexing is 1.02mm. Starting from a first scribed line on a right side, reading tags of ''0'', ''1'', ''2'', ''3'', ''4'', ''5'', ''6'', ''7'', ''8'', ''9'' and ''0'' are successively marked every 5 indexing from right to left. Under the condition that measurement precision does not change, the vernier caliper of the invention is easy to be read. During measuring the length, the vernier caliper of the invention is practical and convenient.
Description
Technical field
The invention belongs to the survey instrument scope, relate to a kind of vernier caliper, particularly a kind of scale division value is the vernier caliper of 0.02mm.
Background technology
Vernier caliper is the dimensional measuring instrument of using always, all indicates the reading groove on the main scale of vernier caliper and the vernier scale.For example, the minimum calibration of 50 calibration vernier caliper main scales commonly used is 1mm, and the length overall of 50 calibration equals 49mm on the vernier scale, and promptly the length of a calibration is merely 0.98mm on the vernier scale.Because the groove on the vernier scale is closeer, when carrying out linear measure longimetry with vernier caliper, the not so good people of eyesight has certain reading difficulty or misreads number easily.
Summary of the invention
The technical matters that the present invention will solve, be exploitation a kind of to make things convenient for the scale division value of reading be the vernier caliper of 0.02mm, the ruling span on its vernier scale is bigger.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
The vernier caliper that a kind of scale division value of the present invention is 0.02mm is made up of main scale and vernier scale, has 50 calibration on the said vernier scale, and the length of each calibration is 1.02mm.The minimum calibration of said main scale still is 1mm.
Rightmost article one groove from the said vernier scale, right-to-left whenever indicate the groove reading mark of " 0 ", " 1 ", " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 7 ", " 8 ", " 9 ", " 0 " successively at a distance from 5 calibration.
The number reading method of vernier caliper of the present invention is similar with the number reading method of vernier caliper commonly used: the reading (reading a millimeter integer) of reading the indicated main scale of the left side on the vernier scale " 0 " groove earlier; Judge that again which root groove on the vernier scale overlaps with groove on the main scale; Read corresponding reading on the vernier scale, be added in the back of main scale reading.
Through technique scheme, the present invention has following beneficial effect: identical with the precision of 50 calibration vernier calipers commonly used, the groove on its vernier scale is comparatively sparse simultaneously, thereby easier reading, and is more practical and convenient when measuring length.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Accompanying drawing is the synoptic diagram that a kind of scale division value of the present invention is the vernier caliper of 0.02mm.
Among the figure: 1. main scale, 2. vernier scale
Embodiment
As shown in the figure, the vernier caliper that a kind of scale division value of the present invention is 0.02mm is made up of main scale 1 and vernier scale 2, has 50 calibration on the said vernier scale 2, and the length of each calibration is 1.02mm.The minimum calibration of said main scale 1 still is 1mm.
Rightmost article one groove from the said vernier scale 2, right-to-left whenever indicate the groove reading mark of " 0 ", " 1 ", " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 7 ", " 8 ", " 9 ", " 0 " successively at a distance from 5 calibration.
During with vernier caliper measurement length according to the invention; Read the millimeter integer reading of the indicated main scale 1 of the left side on the vernier scale 2 " 0 " groove earlier; Judge that again which root groove on the vernier scale 2 overlaps with groove on the main scale 1, read corresponding reading on the vernier scale 2, be added in the reading back of main scale 1.
Scale division value of the present invention is that the measuring principle of vernier caliper of 0.02mm is following: when vernier caliper two measuring claws close up; " 0 " groove of " 0 " groove on vernier scale 2 left sides and main scale 1 overlaps, and " 0 " groove on vernier scale 2 the right just in time overlaps with the 51mm groove of main scale 1.Vernier scale several left the 2nd grooves in 2 the right this moment (reading is the 0.02mm place) are at the 0.02mm place, the left side of the 50mm of main scale 1 groove.When measuring thickness and be the object of 0.02mm, vernier scale 2 0.02mm that moves right, the 2nd groove in vernier scale 2 the right this moment just in time overlaps with the 50mm groove of main scale 1, and the reading of vernier caliper is 0.02mm.The number reading method of all the other length by that analogy.
Claims (2)
1. the vernier caliper that scale division value is 0.02mm is made up of main scale and vernier scale, it is characterized in that: have 50 calibration on the said vernier scale, the length of each calibration is 1.02mm.
2. a kind of scale division value according to claim 1 is the vernier caliper of 0.02mm; It is characterized in that: rightmost article one groove from the said vernier scale, right-to-left whenever indicate the groove reading mark of " 0 ", " 1 ", " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 7 ", " 8 ", " 9 ", " 0 " successively at a distance from 5 calibration.
