Abstract
The utility model discloses a sphere roundness measuring instrument which comprises a support and a detection meter. The support comprises a main body part and a boss part. The main body part is divided into a bottom opening and a cylindrical hollow shell with an upper wall. The boss part is positioned in the middle of the upper wall of the main body part. The center of an upper end of the support is provided with a through hole which penetrates the main body part and the boss part of the support. A meter pole of the detection meter is inserted in the through hole and extends out of the upper wall of the main body part. A positioning threaded hole is horizontally arranged in the excircle of the boss part. A positioning screw is placed in the positioning threaded hole. The lower end of the peripheral sidewall of the main body part is provided with a bayonet, at which a liner is placed. According to the utility model, roundness of a sphere is detected by measuring diameter changes of the surface of the sphere. Measurement precision is high, manufacturing cost is low, and operation is convenient. Measurement can be completed before assembling of the sphere. Repair rate for the assembling of the sphere is reduced, repetitive work rate of an assembler is decreased, and inspection personnel's control power of product quality is raised.
Description
Technical field
The utility model 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.
Utility model content
For solving the problems of the technologies described above, the spheroid roundness measuring instrument that provides a kind of measuring accuracy higher, simple in structure, easy to operate is provided the purpose of this utility model.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model 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 beneficial effects of the utility model are: spheroid roundness measuring instrument of the present utility model, 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 utility model 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 the utility model spheroid roundness measuring instrument coordinates with spheroid.
Fig. 2 is the structural representation of the utility model spheroid roundness measuring instrument medium-height trestle.
Embodiment
