Abstract
Provided is a supporting platform for hardness measurement of a sphere. The supporting platform for the hardness measurement of the sphere comprises a lower section, a middle section and an upper section, wherein the periphery of the lower section, the periphery of the middle section and the periphery of the upper section are cylindrical, tapered inner holes which are the same in taper are formed in the lower section, the middle section and the upper section, the diameter of the tapered inner hole in the position of an upper opening of the lower section, the diameter of the tapered inner hole in the position of an upper opening of the middle section and the diameter of the tapered inner hole in the position of an upper opening of the upper section are different from one another, the upper opening of the lower section and the upper opening of the middle section are respectively provided with a boss with external threads, a lower opening of the middle section and a lower opening of the upper section are respectively provided with a concave hole with internal threads, the depth of each concave hole is larger than the height of each boss, the internal threads of each concave hole are matched with the external threads of each boss, the middle section and the lower section are connected together through the threads, and the upper section and the middle section are connected together through the threads. The supporting platform for the hardness measurement of the sphere carries out location on a detected part through the tapered inner holes, and is stable in supporting, the lower section, the middle section and the upper section can be applicable to detected parts with different diameters, can be independently used, can also be connected and assembled through the threads, and is flexible in matching, and the supporting platform for the hardness measurement of the sphere is simple in integrated structure, convenient to use, low in manufacturing cost and convenient to popularize.
Description
Technical field
The utility model relates to a kind of spheroid hardness and detects brace table, is the brace table of a kind of suitable spheroid, hemisphere or spheroid detection of metal material hardness.
Background technology
Brace table is experiment aid commonly used during material hardness detects, and present brace table is cylinder camber brace table, and namely support slot is to be processed into cylinder camber support slot take right cylinder as matrix, is characterized in that diameter is large, supports face width.In this generic operation, the metal material of spheroid, hemisphere or spheroid can't be stablized placement, easily causes metal material center and check point not to overlap, and causes testing result can not reflect the true hardness of metal material.
Summary of the invention
The purpose of this utility model provides a kind of spheroid hardness and detects brace table, support unstable defective when overcoming existing brace table to spheroid, hemisphere or spheroid detection of metal material hardness, can conveniently support the metal material of different radii spheroid, hemisphere or spheroid.
The purpose of this utility model realizes as follows: this spheroid hardness detects brace table, comprise that periphery is columniform lower joint, middle joint and upper joint, lower joint, middle joint and upper joint have cone-shaped inner hole, the diameter of the place suitable for reading cone-shaped inner hole of lower joint, middle joint and upper joint is different, lower joint, middle joint, upper joint can use separately, and two or three of lower joint, middle joint, upper joint also can be along linking together on the short transverse.
Lower joint and middle joint suitable for reading is with externally threaded boss, the end opening of middle joint and upper joint has the shrinkage pool with internal thread, the degree of depth of shrinkage pool is greater than the height of boss, and the internal thread of shrinkage pool and the external thread of boss are adaptive, and two or three in lower joint, middle joint, the upper joint are threaded connection together.
The cone-shaped inner hole tapering of lower joint, middle joint, upper joint is identical, is convenient to the processing of endoporus; The cone-shaped inner hole of certainly lower joint, middle joint, upper joint also can the tapering difference.
The utility model is located detection piece with taper hole, supports firm; Lower joint, middle joint, upper joint can adapt to the detection piece of different-diameter, can independently use, and also can be threaded connection assembling, and collocation flexibly.One-piece construction is simple, and is easy to use, and cost of manufacture is low, is convenient to promote.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, the utility model comprises that periphery is columniform lower joint 1, middle joint 4 and upper joint 6, and lower joint 1, middle joint 4 and upper joint 6 have the identical cone-shaped inner hole of tapering 3, and the diameter of the place suitable for reading cone-shaped inner hole 3 of lower joint 1, middle joint 4 and upper joint 6 is different.Lower joint 1 and middle joint 4 suitable for reading is with externally threaded boss 2, the end opening of middle joint 4 and upper joint 6 has the shrinkage pool 5 with internal thread, the degree of depth of shrinkage pool 5 is greater than the height of boss 2, the external thread of the internal thread of shrinkage pool 5 and boss 2 is adaptive, and middle joint 4 is threaded connection together with middle joint 4 with lower joint 1, upper joint 6.When the metal specimen material hardness detects, to be detected is positioned in the cone-shaped inner hole 3, stablize test specimen by tangent plane, be fit to stable placement and the detection of spheroid, hemisphere or ellipsoid build metal specimen.
