pin 9, and the distance L2 maximum at the central diameter tooth pitch L more than measured long shaft part 16 or the minimum of a value of the central diameter tooth pitch L equal to measured long shaft part 16 between them add variation in the range of 3mm.So, just can be left, move right sliding axle 10 and utilize the elastic force of spring 4 activity is surveyed activity measuring surface C of pin 5 and fixing measuring surface E surveying pin 9 respectively with processing on lathe after the sawtooth 16-1 left surface N and square tooth 16-2 right flank M of long shaft part 16 that do not take off fit, and by the actual value of distance L2 between activity measuring surface C and fixing measuring surface E surveying pin 9 of measurement activity survey pin 5, draw the actual value of the central diameter tooth pitch L of the right flank M of the left surface N and square tooth 16-2 of sawtooth 16-1, and determine that the actual value of the central diameter tooth pitch L of long shaft part 16 is the most qualified.
The transverse width of the stopper slot of described second positioning seat 6 is more than the diameter dimension 0.2mm of locating part 7, when activity measuring surface C that so can make movable survey pin 5 and measuring surface E fixing survey pin 9 are mutually opposing, does not occur axial wobble poor.
The longitudinally height of the stopper slot of described second positioning seat 6 more than size and the maxima and minima of the central diameter tooth pitch L of measured long shaft part 16 of the diameter of locating part 7 difference and 3mm.So it is able to ensure that movable activity measuring surface C surveying pin 5 fits with long shaft part 16 sawtooth 16-1 left surface N with comparalive ease.
It can be seen from figure 3 that described locating part 7 is straight pin.This makes locating part 7 fairly simple, easily manufactures.
As seen from Figure 5, the middle part of the pedestal 3-1 of described first positioning seat 3 is provided with the endoporus 3-3 of suit sliding axle 10, the diameter of this endoporus 3-3 is set on sliding axle 10 by this endoporus 3-3 gap more than the diameter d10.1mm, the pedestal 3-1 of described first positioning seat 3 of sliding axle 10.This makes the sliding axle 10 can in the endoporus 3-3 of the pedestal 3-1 of the first positioning seat 3 slidably.
From Fig. 6 and Fig. 7, the described movable dynamic survey script body 5-1 top surveying pin 5 is provided with the through hole 5-4 of through left and right, the diameter of this through hole 5-4 is identical with the diameter d1 of sliding axle 10, the described movable movable script body 5-1 that surveys surveying pin 5 is set on sliding axle 10 by this hole 5-4, hole, the location 5-3 that the described movable dynamic survey script body 5-1 top surveying pin 5 is through before and after being additionally provided with, from Figure 12, described sliding axle 10 is provided with and corresponding cooperation positions hole 10-3, as seen from Figure 3, gauge of the present invention also includes keeper 17, described movable pin 5 of surveying is by location hole 5-3, location hole 10-3 is coordinated to use keeper 17 to be fixed on sliding axle 10.This makes movable pin 5 of surveying can be better secured on sliding axle 10.
From Fig. 8 and Fig. 9, the pedestal 6-1 middle part of described second positioning seat 6 is provided with the endoporus 6-3 of suit sliding axle 10, the diameter of this endoporus 6-3 is set on sliding axle 10 by this endoporus 6-3 gap more than the diameter d10.1mm, the pedestal 6-1 of the second positioning seat 6 of sliding axle 10.This makes sliding axle 10 in the endoporus 6-3 of the pedestal 6-1 of the second positioning seat 6 slidably can conveniently operate and use.
From Figure 10 and Figure 11, it is provided with pilot hole 9-3 in the middle part of the fixing survey script body 9-1 of described fixing survey pin 9, the aperture of this pilot hole 9-3 is set on sliding axle 10 by pilot hole 9-3 gap more than the diameter d10.1mm of sliding axle 10, the fixing fixing survey script body 9-1 surveying pin 9.This makes sliding axle 10 in the pilot hole 9-3 of the fixing survey script body 9-1 of fixing survey pin 9 slidably can conveniently operate and use.
From Figure 12, described sliding axle 10 is provided with the spacing hole axially vertical with it, it can be seen from figure 3 that described locating part 7 is fixed in this spacing hole, its upper end or lower end or upper and lower end all stretch out this spacing hole and put in the second positioning seat 6 stopper slot in.This makes simple in construction, easy to manufacture.
Seeing Figure 13, the process of check gauge of the present invention and gauge measurement long shaft part sawtooth and square between cog central diameter tooth pitch is as follows；
The first step, first sloped position face H and I of the first positioning seat 3 of gauge, sloped position face F and G of the second positioning seat 6 are placed in regulator 15-1 of check gauge 15, compression spring 4 makes movable survey pin 5 put into the second of check gauge 15 and measures the left side of tooth 15-3, trip spring 4, utilize the elastic force effect of spring 4, make the left surface J of the second measurement tooth 15-3 of the movable activity measuring surface C automatic paste tightening check gauge 15 surveying pin 5, fixing measuring surface E surveying pin 9 is adjacent to the right flank K of the first measurement tooth 15-2 of check gauge 15, then is zero by the numerical value check and correction of amesdial 14；
Second step, sloped position face H and I of the first positioning seat 3 of gauge and sloped position face F and G of the second positioning seat 6 is placed on the body 16-0 of long shaft part 16, compression spring 4 makes activity survey the left side that pin 5 puts into the sawtooth 16-1 of long shaft part 16, trip spring 4, utilize the elastic force effect of spring 4, make the sawtooth 16-1 left surface N of the movable activity measuring surface C automatic paste tightening long shaft part 16 surveying pin 5, fixing measuring surface E surveying pin 9 is adjacent to the square tooth 16-2 right flank M of long shaft part 16, utilizes the actual value of the central diameter tooth pitch L of amesdial reading long shaft part 16；
3rd step, the actual value of the central diameter tooth pitch L of the long shaft part 16 utilizing amesdial to read is added with the tooth pitch L1 manufacture value of check gauge 15 that (actual value that amesdial reads is the difference of actual pitch diameter tooth pitch L and check gauge 15 tooth pitch L1 after long shaft part 16 manufactures, therefore the actual value that amesdial reads, the actual value of the central diameter tooth pitch L of part 16 should be only) plus the tooth pitch L1 manufacture value of check gauge 15, calculate the actual value of central diameter tooth pitch L between long shaft part 16 sawtooth 16-1 and square tooth 16-2, again by this actual value compared with the sawtooth of long shaft part 16 design code and square between cog central diameter tooth pitch L, thus judge that central diameter tooth pitch L is the most qualified；If the actual value calculated is in the range of the setting of central diameter tooth pitch L, then central diameter tooth pitch L is qualified；If the setting that the actual value of the central diameter tooth pitch L calculated is less than central diameter tooth pitch L, then judge that central diameter tooth pitch L is defective；If the actual value of the central diameter tooth pitch L calculated is more than central diameter tooth pitch L setting, it is possible to according to the direct feed of actual value of central diameter tooth pitch L, proceed processing, until central diameter tooth pitch L is qualified.
