Description

A kind of pit gauge calibration device
Technical field
A kind of pit gauge calibration device of the utility model, what relate to is geometric measurement standard gauge block appliance special for detecting design and manufacturing technology field, is specifically related to be that depth survey meter tool is examined and determine or calibrates special calibration device.
Background technology
Depth gage in micrometric depth gauge, general calipers is the measurement instrument being exclusively used in the degree of depth of measuring workpieces hole or groove and bench height etc. in machinery industry manufacturing industry, then specifies: error of indication of depth micrometer " is examined and determine on 2 grades of optical flats or 0 grade of flat board with 5 gauge blocks such as grade " in JJG24-2003 " micrometric depth gauge " vertification regulation.And point out in JJG30-2012 " general calipers " vertification regulation 6.3.12.1 error of indication clause: for the calibrating of the I type version depth gage error of indication, " be placed on parallel for the gauge block of two groups of same sizes on 1 grade of flat board successively by by dipping cun during measurement; make the long limit of reference field and the long side direction perpendicular contact of gauge block workplace; move blade again; its measuring surface is contacted; during measurement, gauge block should be placed in inner end and the outer end two positions of reference field respectively with flat board." visible, in the calibrating to depth survey meter tool or when calibrating, all be unable to do without dull and stereotyped and these two basic important documents of gauge block, if go out calibrating or when calibrating all kinds of depth survey meter tool, then also needing to carry dull and stereotyped etc. seeming compares effort and inconvenience, and during actual measurement, the bottom measuring surface of one group of gauge block is wanted vertical parallel and is placed on flat board, pit gauge blade is placed in the middle of one group of gauge block, make the long limit of pit gauge chi frame measuring surface and the long side direction perpendicular contact of gauge block workplace, move blade again, blade measuring surface is contacted with flat board, but when measuring because of without fixing component protection gauge block, gauge block very easily knocks over by people's operation, cause gauge block deformation, measuring surface is impaired, indicating value misalignment etc., cause indirect or direct economic loss.
Utility model content
The utility model object is to overcome above-mentioned the deficiencies in the prior art, the calibration method that strategic structural is traditional, dull and stereotyped function is substituted with the reference platform of pit gauge calibration device, and be furnished with the gauge block that two gauge block mobile sockets can insert one group of same size respectively, guarantee that gauge block is safe and reliable when measuring, a kind of pit gauge calibration device of the accurate all kinds of degree of depth of the calibration measurement instrument error of indication of energy.
Its technology is achieved in that and comprises reference seat, gauge block mobile socket, gauge block, it is characterized in that: the length direction of reference seat is provided with dovetail groove, dovetail groove is provided with reference platform, upper left the parting on the right side of the reference seat matched with dovetail groove is not configured with gauge block mobile socket, it is 35mm, the wide rectangular through-hole being 9mm height and being 20mm that gauge block mobile socket inner chamber is provided with long, be inserted with the gauge block of one group of same specification in the rectangular through-hole of gauge block mobile socket respectively, gauge block workplace contacts with the reference platform in reference seat; The gauge block height of described inserted gauge block mobile socket is within the scope of 20mm ~ 1000mm; Between described left and right gauge block mobile socket two longitudinal axis, the distance of movement is in opposite directions that H, H are in the scope of 20mm ~ 130mm.
The beneficial effects of the utility model are: compared with prior art; have simple for structure; small and exquisite practicality; carrying convenience; installation steps are quick; it is steadily reliable that gauge block inserts gauge block mobile socket; accurate positioning; safeguard protection gauge block, and the drawback that can effectively prevent gauge block from easily knocking over when vertical survey, be parallel to each other between one group of gauge block when guaranteeing calibrating or calibrate pit gauge; ensure that the calibration quality of all kinds of pit gauge; reduce labor intensity, save the time, effectively improve work efficiency during all kinds of pit gauge error of indication of calibration.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model spatial structure,
Wherein: 1-reference seat, 1-1-reference platform, 2-gauge block mobile socket, 3-gauge block.
Embodiment
Below in conjunction with accompanying drawing, be example with calibration depth gage after one group of 41.2mm gauge block insertion gauge block mobile socket, the utility model be further described:
See accompanying drawing 1, calibration device comprises reference seat 1, gauge block mobile socket 2, gauge block 3, the length direction of reference seat 1 is provided with dovetail groove, dovetail groove is provided with reference platform 1-1, upper left the parting on the right side of the reference seat 1 matched with dovetail groove is not configured with gauge block mobile socket 2, it is 35mm, the wide rectangular through-hole being 9mm height and being 20mm that gauge block mobile socket 2 inner chamber is provided with long, be inserted with the gauge block 3 of same specification in the rectangular through-hole of gauge block mobile socket 2 respectively, gauge block workplace contacts with the reference platform 1-1 in reference seat 1; Gauge block 3 height of described inserted gauge block mobile socket 2 is at 41.2mm, and between described left and right gauge block mobile socket 2 liang of longitudinal axis, the distance of movement is in opposite directions that H, H are at about 40mm.
See accompanying drawing 1, first, intercept by drawing on reference seat 1 and two gauge block mobile sockets 2 and mill out dovetail groove and reference platform 1-1 respectively, secondly, reference seat 1 is heat-treated, the hardness of reference seat 1 is made to be not less than 63HRC, respectively fine grinding is implemented to reference seat 1 and gauge block mobile socket 2 again, reference seat 1 is on the basis of fine grinding, scraping method is adopted to carry out finishing grinding to the reference platform 1-1 in upper plane, make its 0 grade of plate technique requirement that is up to state standards, its flatness franchise is not more than 3.0 μm, then assemble, make reference seat 1 dovetail groove loads two gauge block mobile sockets 2 symmetrical, the gauge blocks 3 such as 3 grades of 41.2mm or 5 are inserted respectively in gauge block mobile socket 2 intermediate rectangular through hole, one group of gauge block 3 bottom workplace contacts with reference platform 1-1, define one group parallel, definite value, the depth dimensions measurement standard in contour calibration space, between two gauge block mobile socket 2 longitudinal axis, the distance of movement is in opposite directions H, if H is set to 40mm as inner end distance, example: for the depth gage of I type version, when the depth gage of calibration 0mm ~ 150mm, select 41.2mm respectively, 81.5mm, three groups of gauge blocks of 121.8mm, during calibrating, first by very little successively by the middle inner chamber of gauge block 3 vertical parallel placement gauge block mobile socket 2 of first group of same size by dipping, make in the plane of the reference platform 1-1 of lower end workplace perpendicular contact in reference seat 1 of gauge block 3, then, make the long limit of pit gauge chi frame measuring surface and the long side direction perpendicular contact of gauge block 3 upper end workplace, move blade again, blade measuring surface is contacted with reference platform 1-1, then reading on blade, during measurement, in the middle inner chamber of gauge block mobile socket 2, gauge block 3 should be placed in inner end and the Liang Ge position, outer end of chi frame measuring surface respectively, change second group respectively again, 3rd group of gauge block 3, method step is the same, assay approval provides calibration certificate.
