Abstract
The utility model discloses a clamp for testing shear performance of screws. The clamp for testing the shear performance of the screws is used for solving the problem that in the prior art, alignment cannot be easily carried out on loading force in the process of testing the shear performance of the screws. The clamp for testing the shear performance of the screws mainly comprises a cylinder which is formed by two half-cylinder blocks in a combined mode, wherein screw holes which correspond to the screws to be tested are formed in the two half-cylinder blocks, the screw holes penetrate through the radial directions of the two half-cylinder blocks, and are perpendicular to the combination faces of the two half-cylinder blocks, a cylindrical transition block is arranged at the top end of one of the half-cylinder blocks, a cylindrical transition block is arranged at the bottom end of the other half-cylinder blocks, the cylindrical transition blocks are the same in diameter, and the outer end faces of the cylindrical transition blocks are connected with double-screw bolts which are the same in axis and are used for being connected with an upper pull rod or a lower pull rod of a tensile test machine. The clamp for testing the shear performance of the screws is of a symmetrical shape, when the clamp is in operation, the screws to be tested are screwed into the screw holes, a shear test of the screws is carried out through vertical sliding of the left half-cylinder block and the right half-cylinder block, coaxality of shear force can be ensured, operation is convenient and easy, and samples do not slip.
Description
Technical field
The utility model relates to a kind of fixture of testing the screw cutting performance.
Background technology
In parts connect, the screw web member that is absolutely necessary.Due to the difference of parts environment for use, the performance of screw under varying environment becomes the emphasis of concern, is the important safety factor that must consider in structural design.Therefore, the high temperature anti-shear ability of screw becomes one of important performance characteristic in the screw use.Because the shape of screw is special, in shear at high temperature performance test process, loading force is difficult to centering.Present all fixtures of drawing by high temperature equipment only are furnished with the bar of circular section and the plate grip of square-section, also do not have a cover to be fit to the fixture of test screw shear at high temperature performance.
Summary of the invention
The purpose of this utility model is to overcome the prior art defect, and a kind of fixture of testing the screw cutting performance is provided.
the technical solution of the utility model is achieved in that a kind of fixture of testing the screw cutting performance, it is: it mainly closes by two semicolumn agllutinations the right cylinder that forms and forms, the corresponding screw that matches with screw to be measured that has on two semicolumn pieces, described screw run through two semicolumn pieces radially and vertical with its faying face, there is respectively the identical cylinder transition block of diameter the bottom of the top of a semicolumn piece and another one semicolumn piece therein, the cylinder transition block outer face double-screw bolt that be used for connection cupping machine upper connecting rod or lower link identical with axle center is connected.
Further, arrange the screw of 1-3 different size along semicolumn piece axially spaced-apart.
The utility model is symmetric shape, during work, screw to be measured is screwed in screw,, by the shear test that slides up and down to realize screw of left half cylinder piece and right half cylinder piece, can guarantee the alignment of shearing force, and easy to operate simple, and sample is non-slip.

Embodiment
Be further described below in conjunction with accompanying drawing:
as shown in Figure 1, a kind of fixture of testing the screw cutting performance, the main right cylinder that is combined into by two semicolumn pieces 2 forms, the corresponding screw 3 that matches with screw to be measured that has on two semicolumn pieces 2, described screw 3 run through two semicolumn pieces 2 radially and vertical with its faying face, arrange the screw of 2 different sizes along semicolumn piece axially spaced-apart, there is respectively the identical cylinder transition block 4 of diameter the bottom of the top of a semicolumn piece 2 and another one semicolumn piece 2 therein, the cylinder transition block 4 outer faces double-screw bolt that be used for connection cupping machine upper connecting rod 5 or lower link 61 identical with axle center is connected.Semicolumn piece 2, cylinder transition block 4 and double-screw bolt 1 are the one-piece constructions of a time processing moulding.
As shown in Figure 2, during work, left half cylinder piece 2 is connected by cylinder transition block 4 and double-screw bolt 1 with testing machine upper connecting rod 5, and right half cylinder piece 2 is connected by cylinder transition block 4 and double-screw bolt 1 with testing machine lower link 6, and double-screw bolt 1 screws in the upper and lower pull bar center screw of testing machine and gets final product.Upper connecting rod 5 is connected by universal joint with the moving beam 7 of testing machine, test stretch to load by moving beam 7 move up and down realize.During shear test, screw is screwed in screw 3, two semicolumn pieces 2 are by screw lock simultaneously.Owing to axially having the screw of 2 different sizes along semicolumn piece 2, can do the shear test of 2 kinds of specification screws, improved the utilization factor of fixture.Two the semicolumn pieces 2 in left and right slide up and down in process of the test, can not separate, and guarantee that the sample screw only is subjected to the shearing force effect, and distortion does not bend right and left.Notice that the screw two ends will have the yi word pattern opening, test the complete rear convenient sample that takes out.
Claims (2)
1. fixture of testing the screw cutting performance, it is characterized in that: it mainly closes by two semicolumn agllutinations the right cylinder that forms and forms, the corresponding screw that matches with screw to be measured that has on two semicolumn pieces, described screw run through two semicolumn pieces radially and vertical with its faying face, there is respectively the identical cylinder transition block of diameter the bottom of the top of a semicolumn piece and another one semicolumn piece therein, and the cylinder transition block outer face double-screw bolt that be used for connection cupping machine upper connecting rod or lower link identical with axle center is connected.
2. a kind of fixture of testing the screw cutting performance according to claim 1, is characterized in that: the screw of arranging 1-3 different size along semicolumn piece axially spaced-apart.
