Abstract

The utility model provides a slope measuring instrument. A base is connected with a foundation plate through a rotating shaft, so that the foundation plate can rotate along the rotating shaft; the rotating shaft and a standard gauge rod are fixed at the lower end of the foundation plate; an upright post is inserted in the center of the foundation plate; a shell gauge stand capable of sliding along the axis direction of the square-type upright post is arranged on the upright post; and a lever dial indicator is mounted at one end of the shell gauge stand while a pretension device is mounted at the other end thereof. The slope measuring instrument solves the problem that the detection precision of the prior slope measuring instrument is unsatisfactory and the measurement length is limited. By adopting the utility model, after the correction of a standard rectangle ruler, the verticality and the parallelism can be measured and the error can be read out from the dial indicator directly; a gauge block is used as the accessory for rectification, so as to carry out slope measurement, the measurement results can be obtained through calculation, and the precision can reach 0.001. Compared with the prior art, the utility model has the benefits that the slope and the slope errors can be measured conveniently, the verticality, flatness and parallelism can also be detected, and simple structure and operation, high reliability and low cost are achieved.

Description

The natural measurement of tilt instrument
Technical field
The utility model relates to a kind of natural measurement of tilt instrument that is applied to mechanical verification work.
Background technology
In the mechanical processing industry, the special measuring tool that does not also have at present gradient to check, smallclothes generally are placed on workpiece on the sine gauge, in advance the sine gauge pad to theoretical angle, institute's deviational survey degree face is in a horizontal position, by lateral error conversion gradient error.For the general use angle vernier scale of the gradient inspection on the big workpiece, the relatively poor and measurement limited length of accuracy of detection.
Summary of the invention
For overcoming the above-mentioned deficiency of prior art, the utility model provides a kind of can measure gradient and gradient error easily, also can do verticality and the inspection of the flatness depth of parallelism, and simple in structure, simple to operate, reliability height, the natural measurement of tilt instrument that cost is low.
The technical solution of the utility model is: base is connected with foundation plate through turning axle foundation plate can be rotated around turning axle; Turning axle, standard length bar are fixed in the foundation plate lower end; Column is inserted into the foundation plate center; Having on the column can be along square column encapsulation formula gauge stand in axial sliding, and shell type gauge stand one end is installed dial gauge, and the other end has pre-tightening apparatus.
Holddown spring and steel ball and the trip bolt of pre-tightening apparatus on the said shell type gauge stand in shell type gauge stand side opening, installing.
It is consistent with tested angle to adopt slip gauge to adjust the column inclination angle during the utility model value of taking measurement of an angle, and calculates the tested angle actual numerical value by the slip gauge altitude gauge; Adopt slip gauge to adjust benchmark gradient, lever indicator index error when taking measurement of an angle error; Can directly carry out verticality, the measurement of paralleism.
The utility model can be to verticality after the calibration of standard straight angle square, the measurement of paralleism, and error amount is directly read by dial gauge, uses slip gauge to carry out natural measurement of tilt as the annex adjustment, and measurement result draws as calculated, and precision reaches 0.001.Compared with prior art, the beneficial effects of the utility model are: gradient and gradient error be can measure easily, verticality and the inspection of the flatness depth of parallelism also can be done, and simple in structure, simple to operate, the reliability height, cost is low.
Description of drawings
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is a structural representation of the present utility model.

2, base 13 upper and lower surface parallelism errors 0.005, column 1 with the bottom surface error of perpendicularity less than 0.0053, column 1 straightness error 0.001/400mm,
4, two standard length bars (turning axle 11 and standard length bar 12) central plane with base upper and lower surface parallelism error less than 0.005
5, shell type gauge stand 2 slides smooth and easy along column 1.
6, turning axle 11 cooperates degree of tightness suitable with base 13.
It shown in Fig. 2 calibration signal of the present utility model.Calibration: the utility model and marble try square are checked on the platform with being placed on, foundation plate 10 of the present utility model is rotated to bottommost around turning axle 11 make standard length bar 12 contact bases 13 upper surfaces, dial gauge 7 indicators stick the right angle face pressure table 0.2 millimeter of marble try square, slide up and down shell type gauge stand 2, if the motionless then tiltmeter of indicator is qualified, can carry out surveying work, if the indicator number of degrees illustrate then that by deviation tiltmeter does not reach design standards at upper-lower position, grind each component to requiring with reference to technical requirement. get final product the measuring workpieces verticality through the tiltmeter after the calibration, method is identical with calibration.
Among Fig. 3, be depicted as use of the present utility model and promptly measure signal.Measure: gradient workpiece to be measured is placed on the measuring table together with the utility model, calculate the slip gauge height according to the tested angle theoretical value earlier, slip gauge is encased inside between standard length bar 12 and foundation plate 10 upper surfaces, three's contact, again dial gauge 7 indicators are pressed table 0.2~0.5 on inclined-plane to be measured, slide up and down shell type gauge stand 2, observing dial gauge 7 readings changes, corresponding increase and decrease slip gauge height, being adjusted to indicator is zero at the upper-lower position variable quantity, can calculate workpiece actual grade Sina=H/L by measuring slip gauge true altitude value.(L is a length bar centre distance, and H is the slip gauge height)
