6. the method for the gauge using any one of the claims 1 to 5 two symmetrical slope intersection points of measurement to lateral distance, special Sign is: includes the following steps,

Step 1) proofreads the first measuring surface (E3) of snap-gauge on go side (1) and the first measurement inclined-plane (C3) respectively against in go side In the go side measuring surface (E7) and the first inclined-plane (C7) of gauge (6), then by the second measuring surface (E4) of snap-gauge under go side (2) and Second measurement inclined-plane (C4) is led to respectively against in the go side measuring surface (E7) and the second inclined-plane (C8) of go side reference gauge (6) It crosses screw and pin snap-gauge on go side (1) is fixed on the first backing plate (5-2) of connecting plate (5), by screw and pin by go side Lower snap-gauge (2) is fixed on the second backing plate (5-3) of connecting plate (5), then by go side reference gauge (6) from go side snap-gauge (1) It is taken out in snap-gauge under go side (2)；

Step 2 proofreads third measuring surface (E5) and the third measurement inclined-plane (C5) of snap-gauge on not-go-end (3) respectively against in not-go-end In the not-go-end measuring surface (E8) and third inclined-plane (C9) of gauge (7), then by the 4th measuring surface (E6) of snap-gauge under not-go-end (4) and 4th measurement inclined-plane (C6) is led to respectively against in the not-go-end measuring surface (E8) and the 4th inclined-plane (C10) of not-go-end reference gauge (7) It crosses screw and pin snap-gauge on not-go-end (3) is fixed on the third backing plate (5-4) of connecting plate (5), by screw and pin by not-go-end Lower snap-gauge (4) is fixed on the 4th backing plate (5-5) of connecting plate (5), then by not-go-end reference gauge (7) from not-go-end snap-gauge (3) It is taken out in snap-gauge under not-go-end (4)；

Step 3) abuts against the upper datum level (E1) of tested part (8) in the first measuring surface (E3) of snap-gauge on go side (1), will Lower datum level (E2) abuts against in the second measuring surface (E4) of snap-gauge under go side (2), then by tested part (8) forward slip；

Tested part (8) is taken out from the snap-gauge (2) under snap-gauge on go side (1) and go side, then by the upper benchmark of tested part (8) Face (E1) abuts against in the third measuring surface (E5) of snap-gauge on not-go-end (3), and lower datum level (E2) is abutted against snap-gauge under not-go-end (4) The 4th measuring surface (E6) on, then by tested part (8) forward slip；

The judgement of step 4) qualification；

If the first inclined-plane (8-2) and the second inclined-plane (8-3) of tested part (8) can pass through the of snap-gauge (1) on go side simultaneously One measurement inclined-plane (C3) and go side under snap-gauge (2) second measurement inclined-plane (C4), and be tested zero (8) the first inclined-plane (8-2) and Second inclined-plane (8-3) cannot measure the 4th measurement of snap-gauge (4) under inclined-plane (C5) and not-go-end by the third of snap-gauge on not-go-end (3) Inclined-plane (C6), then judge (8) first inclined-plane (8-2) of tested part and the second inclined-plane (8-3) intersection point and upper datum level (E1) and The pre-determined distance (L) of lower datum level (E2) is qualified；

If the first inclined-plane (8-2) and the second inclined-plane (8-3) of tested part (8) cannot pass through the first of snap-gauge on go side (1) Measure the first inclined-plane (8-2) that second of snap-gauge (2) under inclined-plane (C3) and go side measures inclined-plane (C4) or tested part (8) and It second inclined-plane (8-3) can be oblique by the 4th measurement of snap-gauge (4) under third measurement inclined-plane (C5) of snap-gauge (3) on not-go-end and not-go-end Face (C6), then judge (8) first inclined-plane (8-2) of tested part and the second inclined-plane (8-3) intersection point and upper datum level (E1) and under The pre-determined distance (L) of datum level (E2) is unqualified.
