Abstract
The utility model belongs to the technical field of the length measurement type, in particular to a leveling pole division value error calibrator for measuring the special leveling pole division value error, which comprises a working bench, a fixed support arranged under the working bench and a fixed support with a regulating nut. A meter rack is also arranged under the working bench, and a dial gauge is installed on the meter rack. The utility model has the advantage of simple design, low cost and exact measure. The leveling pole division value error calibrator is economical and practical, and the leveling pole division value error calibrator is convenient to be used.
Description
Technical field
The utility model belongs to linear measure longimetry class technical field, the surveyor's staff scale division value that the relates in particular to a kind of special measurement surveyor's staff scale division value error device that calibrates for error.
Background technology
Now the low-angle somascope is used in the measurement of surveyor's staff scale division value error more, low-angle somascope reading device is a vertical optical meter, its error of indication is 0.25 μ m, and measurement range is 500mm, and surveyor's staff is mainly used in the installation of civil construction and common machines, and its scale division value is commonly used is 0.5,1,2,5 and 10mm/m, and the error of indication requires to be not more than 20% of nominal scale division value, so use high-precision low-angle somascope cost height, there is no need; Another is exactly to do standard detection with gauge block measuring on the flat board, because of the gauge block dimension series is a fixed value, can not be combined into arbitrarily angled, so the scale division value error measure is not easy to realize.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of detection that solves surveyor's staff scale division value error is provided, and especially can solve measurement range greater than the surveyor's staff scale division value of the surveyor's staff scale division value error-detecting of the 500mm device that calibrates for error.
The purpose of this utility model is achieved in that and comprises worktable, is arranged on the hold-down support and the hold-down support that has setting nut of worktable below, also is provided with dial framework below worktable, and dial gauge is installed on dial framework.Worktable is that a face length is 600mm, and the flatness of workplace is 0.05mm, and workplace regular length L is long to be 500mm, range deviation Δ L＜3mm.
The utlity model has simplicity of design, with low cost, economical and practical, measure advantage accurate, easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises worktable 1, is arranged on the hold-down support 2 and the hold-down support that has setting nut 3 of worktable 1 below, also is provided with dial framework 4 below worktable 1, and dial gauge 5 is installed on dial framework 4.Worktable 1 is that a face length is 600mm, and the flatness of workplace is 0.05mm, and the regular length L of workplace is long to be 500mm, range deviation Δ L＜3mm.
Before the calibration, earlier with calibration console vertically and surveyor's staff vertically consistent, dial gauge is installed on the rigidity dial framework, the measuring staff axis normal that makes table is in calibration console.The gauge head of adjusting dial gauge contacts with calibration console, and the adjustment nut of rotary work-table makes bubble aim at the start line on the air level left side, the pointer of dial gauge is transferred to whole groove, according to the tested position of surveyor's staff, the adjustment nut of rotational alignment platform makes the pointer of dial gauge rotate corresponding scale then.After treating bubble stabilizes, carry out reading by an end of bubble.Get the mean value of twice reading, read a successively
1, a
2The difference of nominal scale division value and reading value is the error of surveyor's staff left side scale division value.With the scale division value error on same method calibrated horizontal chi the right, get the scale division value error of its maximum difference for this surveyor's staff.
Claims (2)
1, a kind of surveyor's staff scale division value device that calibrates for error, comprise worktable (1), be arranged on the hold-down support (2) of worktable (1) below and have the hold-down support of setting nut (3), it is characterized in that: also be provided with dial framework (4) in worktable (1) below, dial gauge (5) is installed on dial framework (4).
2, a kind of surveyor's staff scale division value according to claim 1 device that calibrates for error, be characterised in that: worktable (1) is that a face length is 600mm, the flatness of workplace is 0.05mm, and the regular length L of workplace is long to be 500mm, range deviation Δ L＜3mm.
