Embodiment
Extremely shown in Figure 5 as Fig. 1, the utility model provides a kind of logical no-go gage for detection of multiple aperture, it is characterized in that: comprise drift group 1, no-go gage group 2 and outer sleeve 3, drift group 1 one ends are positioned at outer sleeve 3, drift group 1 other end stretches out from outer sleeve 3 one ends, no-go gage group 2 one ends are positioned at outer sleeve 3, no-go gage group 2 other ends stretch out from outer sleeve 3 other ends, drift group 1 comprises several drifts, each drift is cavity structure, the drift of drift group 1 is embedded in together, the structure of each drift is identical, and no-go gage group 2 comprises the no-go gage identical with drift group 1 drift quantity, and the structure of no-go gage and drift is identical, size is corresponding one by one with the size of drift, and all no-go gages of no-go gage group 2 are embedded in together.
The xsect of drift, no-go gage and outer sleeve 3 be with circle, rectangle, square or polygon one of them, the logical no-go gage of varying cross-section can be used for detecting the different hole of pass.Equally, when drift and no-go gage are chosen above-mentioned which kind of shape, corresponding outer sleeve is also chosen corresponding shape.
The end that drift and no-go gage are arranged in outer sleeve 3 has flange 4, flange 4 and outer sleeve 3 inwalls of outermost drift are close to, except outermost drift, the drift inwall that the flange 4 of each drift is adjacent is close to, flange 4 and outer sleeve 3 inwalls of outermost no-go gage are close to, except outermost no-go gage, the no-go gage inwall that the flange 4 of each no-go gage is adjacent is close to.Flange 4 has played logical no-go gage socket and the mobile effect of making.
The head edge that drift and no-go gage are positioned at the outer ends of outer sleeve 3 has to turn over and prolongs limit 6.In turn over and prolong limit 6 can prevent from overexerting the time, the logical no-go gage of selecting for use pulled from outer sleeve and separate.
In turn over that to prolong limit 6 heads be smooth head seamed edge 5.Head seamed edge 5 can avoid scratching tested gaging hole.
The end (being the bottom) that drift and no-go gage are arranged in outer sleeve 3 is blind end.These characteristics can be so that small-bore drift or no-go gage (general designation gauge) be when being nested in the bigbore gauge, if the gauge length of different bores is identical, because the existence of blind end is arranged, cause some protrusion of top (maybe can be referred to as to exceed) of small-bore gauge in bigbore gauge top, be more convenient for from the heavy caliber gauge, extracting small-bore gauge like this.
Each drift and no-go gage are positioned at the numbering of useful laser printing on the port sidewall of the outer ends of outer sleeve 3.Outer sleeve 3 sides have the detection diameter value corresponding with the numbering on drift and the no-go gage and distinguish the mark of each drift and no-go gage.Drift and no-go gage are made by Hardmetal materials, are difficult for torsional deformation during use.
The course of work of this example: suppose to make the logical detectable diameter of no-go gage of a smooth circular hole and be 4 ± 0.1,6 ± 0.1,8 ± 0.1,10 ± 0.1,12 ± 0.1,14 ± 0.1mm, 6 sizes are numbered 1～6#, get numbering in the head side of corresponding drift and no-go gage with laser marking machine again, get the mark of the corresponding detection diameter value of numbering and differentiation drift and no-go gage in outer sleeve 3 sides.Be that the logical no-go gage of 4 ± 0.1mm is numbered 1 as detection aperture, detection aperture is that the logical no-go gage of 6 ± 0.1mm is numbered 2, and the like.But drift end mark " T ", but no-go gage end mark " Z ".During use, to require diameter be the smooth hole of 8 ± 0.1mm if need to detect one, and at first extracting respectively from outer sleeve 3 two ends and being numbered the corresponding detection aperture of 3(is 8 ± 0.1mm) drift and no-go gage, detects then.After detection finishes, drift and the no-go gage of extracting pushed in the outer sleeve, for future use.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
