Embodiment
For the technical matters that the present invention is solved, the technical scheme of employing, the technique effect easy to understand of obtaining, the accompanying drawing below in conjunction with concrete is described further the specific embodiment of the present invention.
The invention provides a kind of center distance check tool of through hole, the present invention describes certain automobile front axle parameter as an example of the front axle of certain automobile example: the kingpin bore diameter is Φ 47H8
The diameter in locking bolt hole is Φ
Pitch-row is
With reference to figure 1, Fig. 2, automobile front axle 3 of the present invention, kingpin bore and locking bolt hole are vertical phase perforations, here position with kingpin bore, measure with the locking bolt hole, namely with kingpin bore as pilot hole, with the locking bolt hole as measured hole; Certainly general designer knows, also can position with the locking bolt hole, measures with kingpin bore.But the precision of kingpin bore is higher, and the precision in locking bolt hole is lower, if with the low location, hole of precision, the error of measurement is large.
Cubing of the present invention comprises for the locating shaft 13 that matches with pilot hole, also comprises the measurement axle 2 that detects for inserting measured hole, and described measurement axle comprises that one measures axle go side 23 and and measures axle not-go-end 24.Locating shaft 13 is inserted in the kingpin bore of automobile front axle 3, preferably makes locating shaft 13 and kingpin bore clearance fit, for example quality of fit is H8/g5.This locating shaft further preferably also is provided with a shaft shoulder 14, and this shaft shoulder 14 can be regarded the circle radial protrusion that locating shaft 13 terminations arrange as.The shaft shoulder 14 of locating shaft and front-axle pivot hole end surface are fitted, and the location of finishing locating shaft does not need the operative employee holding up locating shaft after making locating shaft insert kingpin bore.Require the flatness of faying face of the shaft shoulder and front axle less than 0.02mm here, simultaneously with the verticality of the locating surface of locating shaft less than 0.03mm.
For handled easily worker operation, the termination of this locating shaft also is provided with a locating shaft handle 11, and process through annular knurl on the surface of locating shaft handle 11, namely can regard an anti-skidding section as.On this locating shaft handle 11 locating shaft can also be set and beat yard face 12, be used for printing the numbering of cubing, convenient management and regular censorship.
Referring to Fig. 2, reflected more intuitively structure and the using method of measuring axle, measure axle go side 23 and measure the two ends that axle not-go-end 24 is positioned at the measurement axle, be structure as a whole convenient operation so that measure axle go side 23 and measure axle not-go-end 24.Further, the middle part of measuring axle is provided with measures axle handle 21, and this is measured axle handle 21 and is measuring the axle go side and measuring between the axle not-go-end.The same with locating shaft handle 11, measure axle handle 21 preferred through the annular knurl processing, namely can regard an anti-skidding section as.The measurement axle is beaten yard face 22 and is arranged on this measurement axle handle 21, is used for printing corresponding cubing numbering, convenient management and regular censorship.Measuring axle go side 23 and measuring axle not-go-end 24 is to get by Process Dimension Chain Calculating, requires the go side to enter here when detecting, and not-go-end can not enter judges that just workpiece processing is qualified.
Measure the size of axle go side 23 and measurement axle not-go-end 24 by Process Dimension Chain Calculating:
The size L of described measurement axle measure portion
DetectSatisfy following formula:
Wherein, D1 is the diameter of pilot hole; L
Pitch-rowCentre distance for the desired through hole of product; D2 is the diameter of measured hole; d

Subtract ring:
In an embodiment of the present invention, the parameter with reference to above-mentioned obtains L
DetectNumerical value be 9.5mm, this is the basic size of measuring the axle go side and measuring the axle not-go-end.This basic size adds the size that lower deviation can obtain measuring axle go side 23, is calculated as 9.5245mm; This basic size adds the size that the upper deviation can obtain measuring axle not-go-end 24, is calculated as 9.609mm.Consider the tolerance of processing technology, detect the axle go side and be of a size of 9.53 ± 0.005mm, wear limit is 9.525mm, and not-go-end is of a size of 9.595 ± 0.005mm, and the wear limit of locating shaft is 46.98mm.
In order to guarantee the wearing quality of cubing, this cubing adopts GCr15 to carry out Quenching Treatment, and hardness is reached
When detecting:
Can insert in the locking bolt hole if 1 measures axle go side 23, can not enter smoothly and measure axle not-go-end 24, then workpiece is certified products;
Can insert in the locking bolt hole if 2 measure axle go side 23, measure axle not-go-end 24 and also can insert, judge that then the centre distance of through hole is excessive, this workpiece is defective.
Can not insert in the locking bolt hole if 3 measure axle go side 23, judge that then the centre distance of through hole is too small, this workpiece is defective.
With reference to figure 2, general designer knows, this measurement axle go side 23 and measure axle not-go-end 24 can be columned with making.The present invention preferably makes flat, and measuring like this axle go side 23, measuring contacting of axle not-go-end 24 and locating shaft is the line contact, so that measurement is more reliable, measures simultaneously axle and makes flat, and area increases, so more wear-resisting.
Cubing of the present invention, it is simple in structure, can improve the detection efficiency of Vehicular front axle main pin hole and locking bolt hole centre distance, can realize rapidly the full inspection of workpiece.Also reduce simultaneously the labour intensity of workman's operation, avoided the three-dimensional sampling observation to bring the risk of scrapping in batches, reduced the cost that detects.
