Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural representation of flange annular groove quick detection go-no go gauge described in the utility model.
Embodiment
Reference picture 1, Fig. 1 is the structural representation of one specific embodiment of the utility model.
As shown in figure 1, a kind of flange annular groove quick detection go-no go gauge, including go-no go gauge body connecting pipe 10, Yi Jishe
It is placed in the annular groove maximum allowance detection head 20 and annular groove minimal tolerance detection head at the two ends of go-no go gauge body connecting pipe 10
30；The annular groove maximum allowance detection head 20 includes detection lug 22 under detection lug 21 on maximum allowance and maximum allowance, described
Detection lug 22 is circular arc under detection lug 21 and the maximum allowance on maximum allowance and face is symmetrical arranged, and the most grand duke
The center of circle of detection lug 22 is respectively positioned on the axis of the go-no go gauge body connecting pipe 10 under detection lug 21 and the maximum allowance in difference
On, on the maximum allowance under detection lug 21 and the maximum allowance external diameter of detection lug 22 to need the flange annular groove detected
Tolerance maximum；The annular groove minimal tolerance detection head 30 includes detection lug under detection lug 31 in minimal tolerance and minimal tolerance
32, detection lug 32 is circular arc under detection lug 31 and the minimal tolerance in the minimal tolerance and face is symmetrical arranged, and institute
The center of circle for stating detection lug 32 under detection lug 31 and the minimal tolerance in minimal tolerance is respectively positioned on the go-no go gauge body connecting pipe
On 10 axis, in the minimal tolerance under detection lug 31 and the minimal tolerance external diameter of detection lug 32 to need the method detected
Blue annular groove tolerance minimum value.
When the flange annular groove for needing to detect can be by the annular groove minimal tolerance detection head 30, and institute can not be passed through
When stating annular groove maximum allowance detection head 20, then may determine that need detect flange on annular groove be it is qualified, otherwise for
It is unqualified.
It is further preferred that the go-no go gauge body connecting pipe 10 include upper arcuate top wall 11, arc lower bottom wall 12 and
Two flat sidewalls 13 of the upper arcuate top wall 11 and the arc lower bottom wall 12 are connected, two flat sidewalls 13 are mutual
Parallel and face is symmetrical arranged, and detection lug 31 connects the upper arc in detection lug 21 and the minimal tolerance on the maximum allowance
