31, described pressure strip 23 side is communicated with the screw 25 of described through hole 24, uses screw
Protection set 31 is fixed by 25 built-in bolts, and described protection set 31 lower end cutting forms arc
Block 32, vertical to described firm banking 21 upper surface of described gauge head 13 lower end horizontal section
Distance is less than described block arc 32 lower end horizontal section to described firm banking 21 upper surface
Vertical dimension, and difference in height is 1.5mm.
As shown in Figures 2 to 4, the error that sleeve height can allow is ± 0.5mm, passes through
The contrast of standard cartridges, determines the calibrated altitude of sleeve, arranges gauge head 13 lower end horizontal section
Vertical dimension 0.5mm less than sleeve calibrated altitude to firm banking 21 upper surface, is sleeve
The height lower limit that can allow；Block arc 32 lower end horizontal section is set to firm banking 21

To the direction of protection set 31 axial lines, according to several situations occurred below, it is judged that sleeve is high
That spends is whether qualified.
The first situation: sleeve is stretching into during 31 direction of axis line are overlapped in protection by arc
The stop of shape block 32, now illustrates the upper limit that the aspect ratio sleeve height of sleeve can allow
The highest 0.5mm, sleeve excessive height now, do not meet the requirement of production, for defective product
Product.Wherein, block arc 32 lower end horizontal section is the most directly set to firm banking
The vertical dimension of 21 is the upper limit that sleeve height can allow, at this moment when sleeve is stretched into protection set
During 31 direction of axis line, height can directly be hindered by block arc 32 beyond the sleeve of set upper limit
Gear, but bring a drawback simultaneously, along with adding up of measured sleeve number, highly exceed
The lower end horizontal section of the sleeve meeting friction arcuate block 32 of set upper limit, causes the essence measured
Degree declines, so the situation that the producer when of enforcement of reality is typically based on self selects.
The second situation: sleeve does not only have during stretching into protection set 31 direction of axis line
There is the obstruction by block arc 32, and do not touch the bottom of gauge head 13, i.e.
Gauge head 13 does not shrink, and the indicator 14 on indication dial plate 11 does not occur any change,
The lower limit that the height of sleeve can allow less than sleeve height is now described, does not meets wanting of production
Ask, for substandard product.
The third situation: sleeve is not subject to during stretching into protection set 31 direction of axis line
To the stop of block arc 32, but the lower end of gauge head 13 can be touched, and make gauge head
13 shrink, and the contract by distance of gauge head 13 shows turning of in indication dial plate 11 indicator 14
On Dong, indicator 14 often rotates a circle and represents that the distance shunk is 1mm, due to gauge head 13 lower end
Horizontal section is less than block arc 32 lower end level to the vertical dimension of firm banking 21 upper surface
Tangent plane is to the vertical dimension of firm banking 21 upper surface, and difference in height is 1.5mm, i.e. represents survey
1.5mm at most can be shunk in 13 lower ends, reflects to indicator 14 turning on indication dial plate 11
Emotionally condition is a circle half, by observing the rotation situation of indicator 14, if indicator 14 rotates little
In a circle, illustrate that the height error of sleeve, between-0.5mm to+0.5mm, meets the requirements,
If the situation that indicator 14 rotates is between a circle a to circle half, the height error of sleeve is described
Between+0.5mm to 1mm, now the height of sleeve is the highest, undesirable, additionally, real
Border can occur pointer just to rotate the critical condition of a circle, according to manufacturer and client when measuring
Unified suggestion, be considered as qualified products.
