A kind of sphere curvature radius based on above-mentioned measuring device deviates measuring method, comprising the following steps:
Step 1), the assembling present apparatus, fixed dial gauge 1 adjust sliding block 8 to spherical radius size to be measured, then pass through
Standard component calibrates dial gauge 1；
Then present apparatus level after calibration is put into spherical surface to be measured by step 2), make the stabilizer blade 10 and ball to be measured of the present apparatus
Then face contact adjusts 13 contact measured spherical surface of dial gauge gauge head, directly reads dial gauge reading and obtain offset.
A kind of sphere curvature radius measurement method, comprising the following steps:
Step 1), the assembling present apparatus, fixed dial gauge 1, adjustment sliding block 7 to spherical radius size to be measured, fixing leg
10 height；
The present apparatus is placed on standard water plane by step 2), makes stabilizer blade 10 and horizontal face contact, is then adjusted dial gauge and is surveyed
Head and horizontal face contact, return to zero to dial gauge 1 and calibrate；
Step 3), then will zeroing calibration after present apparatus level be put into spherical surface to be measured, make the stabilizer blade 9 of the present apparatus with it is to be measured

(2) if workpiece for measurement be it is aspherical because the aspherical radius of curvature on mutually level circle be it is identical, no
It is different with the radius of curvature at height, it is necessary to so that spherometer keeps horizontal.
It is described further with reference to the accompanying drawing to the structural principle of the utility model and using step:
Specifically, upright guide rail 4 there are three being all provided with centered on through hole center in 2 surrounding of firm banking as shown in Figure 1, Figure 2, three
A upright guide rail 4 is contour, is secured side by side to round 11 upper surface of firm banking, and three upright guide rails 4 are in 120 ° of arrangements, it is ensured that rise
Drop platform 5 remains parallel with firm banking 11 in sliding, then that the protrusion part sliding alignment of ear 3 of lifting platform 5 is perpendicular
It is directly put on upright guide rail 4, will be aligned at the top of lifting platform 5 and upright guide rail 4, locked with locking nut 2, three upright guide rails 4
It to keep being aligned when installation.Lifting platform 5 will remain horizontality in locking, and connecting rod is at this moment connected to cunning by pin
On dynamic ear 3, at this moment sliding block 8 is put into chute of base 9, chute of base 9 and sliding ear 3 are conllinear, adjust 6 other end of connecting rod away from
It connects the connecting rod other end and sliding block with pin, stabilizer blade 10 is screwed into 8 bottom thread hole of sliding block, three stabilizer blades 10
It wants coplanar, firm banking 11 could be made to be parallel to the horizontal plane in this way, then dial gauge 1 is fixed among firm banking 11 and is led to
In hole, the gauge head 13 of dial gauge 1 exposes firm banking 11.
Application method: workpiece for measurement is put on testing stand, after installing device, will first be risen according to approximate diameter and thickness
It drops platform 5 to rise, 10 height of stabilizer blade is mixed up, the distance and workpiece for measurement radius r of adjustment sliding block 8 to 11 through hole center of firm banking
It is identical, dial gauge zeroing correction is then carried out by standard component, when needing to measure radius of curvature, using standard flat and foot bottom
Face contact returns to zero to dial gauge, and when needing to measure offset, the device for adjusting 8 distance of 10 height of stabilizer blade and sliding block is placed
On standard component identical with workpiece for measurement radius r, zeroing calibration then is carried out to dial gauge, then puts the device after calibration
Above to workpiece for measurement, so that whether dial gauge contact 13 touches workpiece surface, if not provided, continuing to adjust dial gauge, directly
Workpiece surface is touched to contact, at this moment can carry out reading measurement.
