Abstract
The invention discloses a sphere roundness measurement instrument. The sphere roundness measurement instrument comprises a bracket and a detection meter, wherein the bracket comprises a main body part and a lug boss part; the main body part is a cylindrical hollow shell with an opened bottom and a top wall; the lug boss part is located at the center of the top wall of the main body part; a through hole is formed in the center of the upper end of the bracket; the through hole penetrates through the main body part and the lug boss part of the bracket; a meter rod of the detection meter is inserted into the through hole and stretches out of the top wall of the main body part; a positioning threaded hole is formed in the outer circle of the lug boss part in the transverse direction; the positioning threaded hole is internally provided with a positioning screw; a clamping opening is formed in the lower end of the peripheral side wall of the main body part; the clamping opening is provided with a liner. According to the sphere roundness measurement instrument, the roundness is detected by measuring the change of diameters of all parts of a sphere surface; the sphere roundness measurement instrument is high in measurement precision, low in production cost and convenient to operate so that the measurement can be finished before a sphere is assembled, the repair rate of the assembled sphere is reduced, the repeated working rate of an assembler is reduced and the control on product quality by inspection personnel is improved.
Description
Technical field
The present invention relates to a kind of measurement mechanism, particularly a kind of spheroid roundness measuring instrument.
Background technology
The circularity of spheroid affects the goodness of fit of spheroid and valve seat.If the goodness of fit is high, increases the resistance that fluid moves along sealing surface, thereby improve sealing.The roundness tolerance of General Requirements spheroid is 10 grades that in GB 1184-80 < < geometrical and toleranging numerical value > >, stipulate, and spheroid circularity is difficult to easy mode Measurement accuracy, existing spheroid roundness measuring instrument or measuring accuracy are not high, or complex structure, price is high, use is inconvenient, as three-coordinates measuring machine etc.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide higher, simple in structure, the easy to operate spheroid roundness measuring instrument of a kind of measuring accuracy.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions: a kind of spheroid roundness measuring instrument, comprise support and detection table, described support comprises main part and projection section, described main part is bottom end opening, cylindrical, hollow housing with roof, described projection section is cylindrical-shaped structure, and this projection section is positioned at the roof center of described main part, the center of the upper end of support has through hole, this through hole runs through the main part of support and the projection section of support, the table bar of detection table inserts in described through hole, and stretch out in the roof of main part, on the cylindrical of the projection section of support, be laterally provided with positioning spiro pit, dog screw is housed in positioning spiro pit, the circumferential side wall lower end of the main part of described support has bayonet socket, liner is equipped with at this bayonet socket place.
Further, the bottom inside of described liner is inclined-plane.
Further, the axle center with respect to support on the roof of the main part of described support is arranged with two threaded holes, and these two threaded hole places are all provided with screw element.
Further, two described screw elements have been lifting bolt or the bolt of fixing and gripping effect.
The invention has the beneficial effects as follows: spheroid roundness measuring instrument of the present invention, can be when measuring spheroid circularity, the spherical calotte of spheroid is placed in to the inside of the main part of support, be inserted in the gauge outfit of detection table and the sphere-contact of spheroid of the through hole of support, screwed in place screw positions detection table table body, then by both hands, pull two screw elements and carry out rotating sphere roundness measuring instrument, make the gauge outfit of detection table can contact the sphere of the different parts of spheroid, variation by different spheres position diameter is reflected to the swing that detects list index, thereby detect the circularity of spheroid.Spheroid roundness measuring instrument measuring accuracy of the present invention is higher, easy to operate, make spheroid just can complete measurement before assembling, the repair rate of assembling spheroid is lowered greatly, reduce millwright's duplication of labour rate, improved the control dynamics of reviewer to product quality.
Accompanying drawing explanation
Fig. 1 is the structural representation that spheroid roundness measuring instrument of the present invention coordinates with spheroid.
Fig. 2 is the structural representation of spheroid roundness measuring instrument medium-height trestle of the present invention.
Embodiment
