Abstract

The utility model relates to a straight steel ruler calibrating installation, main part platform (1) is the cuboid structure, has offered gage block groove (3), gauge groove (4) and has awaited measuring chi groove (5), and gage block groove (3) are used for placing standard gauge block (2), utilize the working face of standard gauge block (2) to form measuring basis face E, and gauge groove (4) keep unanimous than chi groove (5) the high 1mm that awaits measuring, width with the third -class standard metal standard meter of national standard. Through setting up reasonable gauge groove and awaiting measuring chi groove and reference surface, can pass through the reference surface parallel and level with the gauge and the chi that awaits measuring, be convenient for detect and reach corresponding technical requirement, reduce the abbe error, reduce the error of indication that the neat problem of zero terminal pair was brought, improve work efficiency.

Description

A kind of steel straight ruler verification device
Technical field
The present invention relates to a steel straight ruler verification device, belong to measurement standard field tests.
Background technology
Carry out now examining and determine that the method for Steel Ruler follows is abbe ' s principle in geometry metrology, but adjusting tested footage number in current detection method there is the side of groove brought Abbe error parallel with the chi limit of gauge larger; Rely on visual observation in its zero end of tested straight steel ruler and third-class standard metal strain line chi zero end groove or arbitrarily large scale groove alignment procedure, cause the error of indication larger like this;
Summary of the invention
The technical problem to be solved in the present invention: adjusting tested footage number in traditional detection method has the problem that the side of groove brought Abbe error parallel with the chi limit of gauge is larger.
Beneficial effect of the present invention: this device is by arranging rational gauge groove and treating measuing tape slot and reference field, can be concordant by reference field with chi to be measured by gauge, be convenient to detect and reach corresponding technical requirement, reduce Abbe error, reduce the error of indication that zero end alignment problem brings, increase work efficiency.
Technical solution of the present invention is, a kind of steel straight ruler verification device, its overall aluminum alloy materials that adopts is made, it is characterized in that, main body platform 1 is rectangular structure, offers gauge block groove 3, gauge groove 4 and treats measuing tape slot 5, gauge block groove 3 is for placing standard gauge block 2, utilize the workplace of standard gauge block 2 to form measurement datum E, gauge groove 4 is than treating the high 1mm of measuing tape slot 5, and width and country third-class standard metal strain line meter ruler is consistent.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present invention, and wherein, 1 is main body platform main body platform, and 2 is standard gauge block, and 3 is gauge block groove, and 4 for gauge groove 5 is for treating measuing tape slot.
Fig. 2 is operating diagram of the present invention, wherein, A face is third-class standard standard line meter basal plane, B face is tested straight steel ruler basal plane, C face is the basal plane of the non-strain line side of third-class standard standard line meter, and D face is the basal plane of the non-strain line side of tested straight steel ruler, and E is the workplace of fourth class standard gauge block, M6 is screw thread oral pore, fixing third-class standard standard line meter end face center.
Embodiment
Below in conjunction with Figure of description, installation of the present invention and working method are described.
The first step, designing requirement
(1) Abbe error in measuring process is reduced;
(2) can realize itself and small change easily and fast and exactly;
(3) work efficiency of testing person is improved.
Second step, design concept
Calibrating installation adopts good, that wearing quality the is strong aluminum alloy materials of hardness to process.Third-class standard metal strain line chi is placed on the A face of calibrating installation, and tested straight steel ruler is placed on the B face of calibrating installation, as shown in Figure 2.
Wherein A face be pendulum at the basal plane of third-class standard metal strain line chi, B emerges the basal plane of pendulum in tested Steel Ruler, and on calibrating installation, the intersection in A face and C face is that third-class standard metal strain line chi lies against A face side and leans on the baseline with C face.A face is higher than B face 1mm, and object is to make the survey limit of the side of tested steel plate tape groove and third-class standard metal strain line tape groove in same plane.The depth of parallelism in A face and B face, the intersection ground depth of parallelism in the intersection in A face and C face, B face and D face is extremely important, because it directly affects Abbe error.Therefore the depth of parallelism in A face and B face is designed to 0.03mm, the intersection in A face and C face, and the intersection in B face and D face is designed to 0.03mm relative to the depth of parallelism in A face.
B face is opened the groove of a wide 12mm, dark 3mm, and select a fourth class gauge block, be put in groove by gauge block workplace perpendicular to B face, a wherein workplace of gauge block is as small change reference field, and another side need be close on calibrating installation.Gauge block exposes the height of groove should higher than A basal plane, therefore the specification of selected gauge block is 8mm.
The end face of calibrating installation bores a threaded hole, as the screw for M6.When third-class standard metal strain line chi lie against A basal plane be against on the intersection in A face and C face time, it is just corresponding to the center of third-class standard metal strain line meter ruler end face that this threaded hole obtains position, when making screw rotate adjustment, spiral shell head is in the center withstanding on third-class standard metal strain line chi section, ensure that in adjustment process, the acting force of screw to third-class metalloid linear scale end face substantially overlaps with the axis of pitch of linear scale, offset in order to avoid linear scale rotates in the adjustment process of top at tested spiral shell head.
3rd step, calibration method
Calibrating installation is positioned on one-level marble flat board, with third-class metal lines chi constant temperature together with tested straight steel ruler, be placed on the A basal plane of calibrating installation with third-class standard metal strain line meter ruler, make a side of third-class metal lines meter ruler extremely lean against the intersection in A machine side and C face, end face leans against on E face.
Adjustment M6 screw, make it withstand on third-class standard metal strain line chi end face center, slowly screw screw, and be the magnifier of 5 times by enlargement factor, the non-working surface of visual observations third-class standard metal strain line chi zero graduation strain line and gauge block and workplace seamed edge are to it.
Tested Steel Ruler is put on B basal plane, makes the band line scale side of its tested straight steel ruler extremely lean against B basal plane and D face intersection, make its tested inspection straight steel ruler termination lean against on the workplace of gauge block simultaneously.
Tested straight steel ruler total length and the end face of arbitrary strain line to chi or the error of indication of end is read with the magnifier that enlargement factor is 5 times.
