It sets, along the direction that first end 11 is directed toward second end 12, the distance between each point and true edge 14 increase in the section that broadens 151；Deng
Wide section 152 parallel with true edge 14, and one wide section 152 forms a reference section 16 with true edge 14.
Specifically, the angular range to broaden between section 151 and true edge 14 is 5 ° to 20 °.In the present embodiment, broaden section
151 and the angle of true edge 14 are 11.3 °.
Graduation indication area, cross section ruler of the graduation indication area with instruction measuring scale 1 at this are provided on measuring scale 1
It is very little.In the present embodiment, the minimum scale unit in graduation indication area is 1mm.
Measuring scale 1 further includes operation ring 13, and operation ring 13 is connected with second end 12, convenient in survey crew's measurement process
Operation.
When the measuring scale 1 provided through this embodiment measures, measurement method includes the following steps：
Setting procedure：Two target fiducials portions 16 are determined according to gap width permissible value range, make two target fiducials portions
Size range determined by 16 is no more than the permissible value range of gap width；
Operating procedure：The first end 11 of measuring scale 1 is protruded into gap, until measuring scale 1 is abutted with clearance margin；
Reading step：Whether the abutment for observing and measuring ruler 1 and clearance margin is located between two target fiducials portions 16；
Reading step carries out after operating procedure completion.
Further, in operating procedure, the direction of true edge 14 and the depth direction in gap are consistent.
For example, the margin of tolerance allowed is ± 0.5mm if the design size in a gap to be measured is 3mm, then walked in setting
In rapid, the reference section 16 having a size of 2.5mm and the reference section having a size of 3.5mm 16 are determined as two target fiducials portions 16.?
In operating procedure, the first end 11 of measuring scale 1 is protruded into gap, until measuring scale 1 is abutted with clearance margin.In reading step
In, whether the abutment for observing and measuring ruler 1 and clearance margin is located between the reference section 16 of 2.5mm and the reference section 16 of 3.5mm.
If the abutment of measuring scale 1 and clearance margin is located between two target fiducials portions 16, the width in gap meets tolerance.
If the abutment of measuring scale 1 and clearance margin is located at except two target fiducials portions 16, the width in gap is unsatisfactory for tolerance and wants
It asks, at this point it is possible to determine the gap of clearance diameter range between gap width actual value and permission according to the reading at abutment.
Embodiment 2
Please refer to Fig. 2.The present invention provides a kind of measuring scale 1, and this measuring scale 1 includes first end 11 and second end 12；Edge
First end 11 is directed toward on the direction of second end 12, and the cross sectional dimensions of measuring scale 1 increases；Measuring scale 1 is equipped with several benchmark
Portion 16, at reference section 16, the cross sectional dimensions of measuring scale 1 is constant.
In several reference sections 16, one of reference section 16 is used to allow size suitable with the minimal design to gaging hole
Match, another reference section 16 is used to allow size fit with the design maximum to gaging hole.If having multiple to gaging hole, measuring scale 1
It is upper that there are multiple reference sections 16.For example, existing multiple to gaging hole, the diameter permissible value range in each hole is：3mm±0.5mm,
3mm ± 0.7mm, 3mm ± 1.0mm, then measuring scale 1 is 2mm, 2.3mm, 2.5mm, 3.5mm, 3.7mm and 4mm in cross sectional dimensions
Place is respectively arranged with reference section 16.Between each reference section 16, the cross sectional dimensions of clearance ruler is gradually increased.
Further, the cross section of measuring scale 1 is circle.Since the diameter in hole has multiple directions, by the cross of measuring scale 1
Section is designed as the round detection that can preferably adapt to hole.
Measuring scale 1 further includes operation ring 13, and operation ring 13 is connected with second end 12, convenient in survey crew's measurement process
Operation.
When the measuring scale 1 provided through this embodiment carries out inside diameter measurement, measurement method includes the following steps：
Setting procedure：Two target fiducials portions 16 are determined according to bore dia permissible value range, make two target fiducials portions 16
Identified size range is no more than the permissible value range of bore dia；
Operating procedure：The first end 11 of measuring scale 1 is protruded into hole, until measuring scale 1 is abutted with aperture；
Reading step：Whether the abutment for observing and measuring ruler 1 and aperture is located between two target fiducials portions 16；
Reading step carries out after operating procedure completion.
Further, in operating procedure, the axis direction of measuring scale 1 and the depth direction in hole are consistent.
For example, if one to gaging hole design diameter be 3mm, allow the margin of tolerance be ± 0.5mm, then in setting procedure
In, the reference section 16 having a size of 2.5mm and the reference section having a size of 3.5mm 16 are determined as two target fiducials portions 16.It is grasping
Make in step, the first end 11 of measuring scale 1 is protruded into hole, until measuring scale 1 is abutted with clearance margin or aperture.It is walked in reading
In rapid, whether the abutment for observing and measuring ruler 1 and aperture is located between the reference section 16 of 2.5mm and the reference section 16 of 3.5mm.If
The abutment in measuring scale 1 and aperture is located between two target fiducials portions 16, then the diameter in hole meets tolerance.If measuring scale
1 is located at except two target fiducials portions 16 with the abutment in aperture, then the diameter in hole is unsatisfactory for tolerance, at this point it is possible to root
The gap of the pore diameter range of aperture actual value and permission is determined according to the reading at abutment.
In conclusion measuring scale 1 provided by the invention has the advantages that：
1. whether the abutment for observing and measuring ruler 1 and gap or hole is located between target fiducials portion 16, if position in measurement
Between selected two target fiducials portions 16, then illustrate that the diameter in gap width or hole meets design requirement.It so can be with
The quick judgement for realizing gap width and bore dia, individually compares step without carrying out again.
2. making a reference section 16 for allowing size fit with the minimal design in gap to be measured, another reference section 16 is used
In allowing size fit with the design maximum in gap to be measured, as long as then measurement spot size is located between the two reference sections 16 i.e.
It can.
3. measuring scale 1 provided by the invention not only can be used for measuring aperture, but also can be used for measuring gap width.
Since the quantity in hole or gap on stamping parts of automobile is more, measuring scale 1 provided by the invention is especially suitable
Quick detection for stamping parts of automobile.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
