Summary of the invention
Technical matters to be solved by this invention provides a kind of measurer of measuring the concentric spherical semidiameter, to solve the problems of measurement of concentric spherical semidiameter.
For solving the technical matters that exists; The technical scheme that the present invention adopts is; Measure the measurer of concentric spherical semidiameter, comprise support bar, sounding rod, pedestal, holding screw, it is characterized in that: when sphere is calibrated in said base bottom surface contact; The contact point of base bottom surface is in same plane, and the plane that the contact point of base bottom surface is formed is tangent with the calibration sphere; Said sounding rod is installed on the pedestal; During sounding rod bottom surface contact calibration sphere; The contact point of sounding rod bottom surface is in same plane; Sounding rod bottom surface and the plane and the base bottom surface of the contact point composition of calibration sphere and the plane parallel of calibrating the contact point composition of sphere, and the sounding rod bottom surface overlaps with the planar central vertical line of the contact point composition of calibrating sphere with planar central vertical line and the base bottom surface that the contact point of calibration sphere is formed; Said support bar is installed on the side arm of pedestal, and corresponding holding screw is installed.
Owing to can confirm a plane at 3, the bottom surface of pedestal contact calibration sphere can be made into difformity according to the measurement environment of measured concentric spherical.The both sides of usually, sphere is calibrated in said base bottom surface contact make becomes the cylinder side of diameter less than the calibration spherical diameter.
By on can know that the sounding rod bottom surface can have any shape, like triangle, square, circular or linear, but have certain error when measuring.Usually, should be with said sounding rod bottom surface and calibration being contacted with a bit of sphere, and this contact point is positioned on the planar central vertical line that base bottom surface and the contact point of calibration sphere form.Best, the bottom that sphere is calibrated in said sounding rod contact is spheroid or cone.
But said sounding rod accepted scale, vernier caliper, rotation milscale etc. can be selected according to measuring accuracy.
Leave the support rod hole with a plurality of installation support bars of pedestal center different distance on the side arm of the one or both sides of said pedestal respectively, and corresponding holding screw is installed.So that the size according to measuring concentric spherical is carried out suitable choice.
Usually, the bottom of support bar contact calibration sphere can be different shape.Best, the bottom that sphere is calibrated in said support bar contact is spheroid or cone.
Beneficial effect of the present invention:
The present invention has quoted the direct semidiameter of measuring two concentric spherical zones of measuring principle of screw pair, has solved the measurement difficult problem about two cloudy ball homocentric spheres dribbling footpath semidiameters.The invention solves the only measurement of the measurement spherical zone semidiameter under the centre of sphere situation of concentric spherical zone part,, be reduced to the direct measurement of bidimensional the measurement of 3 D complex shape.Characteristics of the present invention are simple in structure, and are easy to operate, characteristics such as efficiency of measurement and precision height.Successfully developed the measurer of the concentric spherical zone semidiameters of two cloudy balls, utilized this cover measurer can satisfy the accuracy requirement of product, effect is good.
The present invention is simple in structure, and is easy to operate, the characteristics that efficiency of measurement and precision are high.Not only can adapt to the measurement of producing in batches especially to the measurement of the seal groove degree of depth in spherical crown, the spherical zone simultaneously to two measurements with the heart-yin ball spherical crown, spherical zone semidiameter.
