Specific embodiment
In order to which those of ordinary skill in the art can sufficiently implement the present invention, with reference to the accompanying drawing and specific embodiment come into
One step illustrates the content of present invention.
A kind of shaft box spring position of mounting hole metrization detection method is connected by detection 2 center of shaft box spring upper end mounting hole
Projection and the angle γ size of the line of centres of the lower bottom part mounting hole 3 of the line in 3 place plane of lower bottom part mounting hole, judgement
Whether shaft box spring position of mounting hole degree is in the margin of tolerance.
As shown in Figure 1, not due to the line of centres of 2 line of centres of shaft box spring upper end mounting hole and lower bottom part mounting hole 3
It projects in approximately the same plane, therefore by 2 line of centres of shaft box spring upper end mounting hole to 3 place plane of lower bottom part mounting hole,
The angle measurement angle measurement in its spatial dimension converted in plane.
It is projected as x-axis in 3 place plane of lower bottom part mounting hole with 2 line of centres of upper end mounting hole, with the x-axis
Vertical line is that y-axis establishes plane coordinate system, passes through the size detection institute of detection 3 line of centres of lower bottom part mounting hole and the angle α of y-axis
State angle γ size, the angle α=90 °-γ.
For convenience of measurement and the determination of reference axis, plane coordinates is established in the plane of 3 place plane of lower bottom part mounting hole
Mounting hole 2 line of centres in upper end is projected as x-axis and in 3 place plane of lower bottom part mounting hole with the foundation of the vertical line of x-axis by system
Y-axis, angle, that is, 3 line of centres of lower bottom part mounting hole of 2 line of centres of upper end mounting hole and 3 line of centres of lower bottom part mounting hole
It is convenient for subsequent trigonometric function operation with the angle γ of x-axis, it is further converted to measurement 3 line of centres of lower bottom part mounting hole and y
The size of the angle α of axis, it is clear that angle α=90 °-γ.Since the line of centres of shaft box spring lower bottom part mounting hole 3 is a given value,
Therefore
Angle α is detected by distance of the measurement lower bottom part mounting hole 3 on the direction of the x-axis.Since shaft box spring lower bottom part is pacified
The line of centres distance L for filling hole 3 is a given value, therefore the sine value of angle α is lower bottom part mounting hole 3 in the x-axis
Distance/shaft box spring lower bottom part mounting hole 3 line of centres distance on direction, thus converts the measurement of angle to the survey of distance
Amount.
Using the central axes of shaft box spring as z-axis, space coordinates are established with the x-axis and y-axis, determine detection plane Q, it is described
It is parallel and vertical with x-axis with z-axis to detect plane Q；Difference in height Δ H inspection by measurement lower bottom part mounting hole 3 apart from detection plane
Survey angle α.
As shown in Fig. 2, to be further convenient for measuring distance detection of the lower bottom part mounting hole 3 on the direction of the x-axis
The central axes of shaft box spring are determined as z-axis and determine a detection plane Q parallel with z-axis and vertical with x-axis, respectively by angle α
Height H1 and H2 by measurement lower bottom part mounting hole 3 apart from detection plane, computed altitude difference Δ H=H1-H2, it is clear that sin α=
Sin β=△ H/L, it can thus be appreciated that α=β=arcsin (△ H/L).It can judge that shaft box spring threaded hole is pacified by above method
Whether holding position degree α is qualified.Such as: journal box spring angle [alpha] require for 20 ± 2 ° (18 ~ 22 °), two threaded hole center of housing away from L=
264mm brings angle [alpha] and L into formula sin α=sin β=△ H/L, and 3 center of lower bottom part mounting hole hole and detection plane can be obtained
Q difference in height △ H=(81.58 ~ 98.89) mm, if △ H, within the scope of (81.58 ~ 98.89) mm, angle [alpha] is qualified, otherwise angle [alpha]
It is unqualified.In conclusion plane Q difference in height △ H can be detected by detection shaft box spring bottom mounting apertures centre distance to determine
Whether journal box spring angle [alpha] is qualified.

36 are detachably connected with the use of detection platform 8.It is described to be close to tooling 25 and to be close to tooling 36 vertical with detection platform 8.
The upper surface for being close to tooling 25 is circular arc corresponding with shaft box spring mandrel end concave surface, is close to tooling 36
Upper surface is circular arc corresponding with shaft box spring mandrel outer circle portion concave surface.In order to be close to tooling 25 and be close to tooling 36 and shaft box spring
The better compatible degree in outer surface is close to tooling 25 with the upper surface for being close to tooling 36 and is preferably designed for shaft box spring mandrel end pair
The circular arc concave surface and circular arc corresponding with shaft box spring mandrel outer circle portion concave surface answered, such shaft box spring are being placed to being close to tooling 25
When with being close in tooling 36, no clear gap and supportive is best.
By the position restriction for being close to tooling 1, being close to tooling 25 and being close to 36 pairs of shaft box springs of tooling, lower bottom part is measured
The position degree occurrence of shaft box spring mounting hole can be calculated apart from 8 difference in height of detection platform for mounting hole 3.In practical application
In, the same special screw thread feeler gauge of two specifications is installed in axle box bullet lower bottom part mounting hole 3, and measure 2 with height gauge
Threaded hole center and monitor station plane 8 distance H1 and H2, and difference in height △ H △ H=H2-H1 is calculated, pass through trigonometric function
The specific angle value of position degree of transformation you can get it shaft box spring mounting hole.
In actual use, due to the discreteness of shaft box spring external dimensions, in order to ensure the central axes z-axis and inspection of shaft box spring
It is parallel to survey platform 8, further includes being movably arranged on going up and down in detection platform 8 being close to tooling 1 and being close between tooling 25
Chain-wales 10, the lifting chain-wales 10 can adjust shaft box spring by lifting and decline certain altitude and be placed on and be close to tooling 1
To height of the 36 rear axle casing spring mandrel of tooling apart from detection platform 8 is close to, go up and down chain-wales 10 and microheight gauge by mandrel away from
Monitor station is H3-H4=0 apart from difference in height zeroing, to guarantee that Z axis and plane where X/Y axis are vertical, flat with detection platform 8
