Raw interference.
5 of the positioning end 1-1 of the locating shaft 1 to the position length L2 measured on the left of axle 2 than measured bearing track seat
The step big 10mm of height D3 long, the effect that this causes to prevent interference is preferable.
On the left of the left end of the measurement plate 3 to positioning end 1-1 to measurement axle 2 of the length L1 than locating shaft 1 for measuring axle 2
At least big 15mm of position length L2.The benchmark of lower measuring surface J and measured the bearing track seat 5 of measurement plate 3 when this causes measurement
Measuring surface K can be contacted preferably, and convenient operation.
The left end of the measurement plate 3 extremely measures the positioning of axle 2 to the length L1 for measuring axle 2 than the positioning end 1-1 of locating shaft 1
The big 20mm of length L2.Such using effect is more preferable.
It is shown in Figure 5, the method that the present invention measures the orbit altitude of bearing track seat using above-mentioned gauge.Including following
Step；
First, the lower measuring surface J of the measurement plate 3 of the gauge is put the bearing rail being still installed on after processing on lathe
On the reference measurement face K of the 5 of road seat；
Then, to the axle center traverse measurement plate 3 of bearing track seat 5, and effect using position-limit mechanism 6 makes the phase of measurement axle 2
Slided up and down for measurement plate 3, drive the positioning end 1-1 and the bearing track 5-2 of measured bearing track seat 5 of locating shaft 1 to fill
Tap is touched, and the center line of locating shaft 1 is overlapped with the center line of the bearing track 5-2；
Then, measured using knife straightedge measurement axle 2 datum level B and measurement plate 3 first on measuring surface A or the
Position on two between measuring surface C, judges whether orbit altitude H sizes are qualified；
If datum level B is higher than measuring surface A on first, orbit altitude H off-dimensions are judged；
If datum level B it is concordant with measuring surface A on first or less than first on measuring surface A but higher than second on measuring surface
C, or it is concordant with measuring surface C on second, then judge orbit altitude H size qualifications；
If datum level B is less than measuring surface C on second, orbit altitude H off-dimensions are judged.
Gauge of the invention and method implementation method are explained in detail above in conjunction with accompanying drawing, but the present invention is not limited
In above-mentioned implementation method, in the ken that one skilled in the relevant art possesses, can also be to gauge of the invention
Many variations are made with method.For example, for gauge of the invention, its stop screw 4 can be spacer pin, correspondingly the spiral shell
Hole 3-1 is pin-and-hole, and the spacer pin is installed in pin-and-hole, and its end is located in the stopper slot 2-1.This causes gauge of the invention
When the relevant components part of position-limit mechanism changes within the specific limits, it is also possible to use.
