Abstract
The utility model discloses a single shear test device for square section samples. The device comprises two cutouts. Each of the cutouts is equipped with a square slot. With the two cutouts being attached, samples are placed in a square space formed by the square slots thereof. One cutout is arranged above the other one. A guide-way plate is arranged outside each of the cutouts. The two guide-way plates are connected via a connecting piece. Single shear tests of square section samples are carried out effectively by utilizing the above device provided by the utility model, wherein the samples are replaced conveniently. Single shear tests which are carried out on samples of square section of different sizes can be carried out easily by changing the sizes of the square slots of the cutouts.
Description
Technical field
The utility model relates to a kind of shearing test device, and the simple shear of particularly a kind of square-section sample is cut test unit.
Background technology
At present, shearing test device often adopts the shearing jaw seat of casting to finish test with the mode that shearing jaw and cutout cooperate, this mode can only be finished the cross section and be circular double-shear test, can't finish the cross section is that square simple shear is cut test, also is difficult to solve the long problem of shearing jaw seat process-cycle of casting.。
Summary of the invention
The technical problems to be solved in the utility model is: it is that the simple shear that square simple shear is cut the square-section sample of test is cut test unit that a kind of cross section of can finishing is provided.
In order to solve the problems of the technologies described above, the utility model comprises two cutouts, a square groove is respectively arranged on two cutouts, the synthetic square space that holds sample of square groove when two cutouts are fitted on two cutouts, and a cutout is higher than another cutout, two cutouts respectively are provided with a guide rail plate outward, and two guide rail plates connect by web member.
In order better to connect and to be convenient to change sample, described web member is a screw and nut.
In order to reduce friction to greatest extent, be provided with two needle roller plates and Duo Gen needle roller between described each cutout and the guide rail plate that is adjacent, two needle roller plates are fixed on the guide rail plate, many all rotating being arranged between two needle roller plates of needle roller, and cutout contacts with needle roller.
For fixed, described needle roller plate is positioned in the groove of guide rail plate, and needle roller plate and guide rail plate are fixed by straight pin.
The beneficial effects of the utility model are: it is that square sample simple shear is cut test that the utility model can effectively be finished the cross section, and can change sample easily.When the cross section that will do different size is the simple shear of square sample when cutting test, the groove size of change cutout just can conveniently be finished.

Wherein: 1, guide rail plate, 2, cutout, 3, needle roller, 4, the needle roller plate, 5, sample, 6, nut, 7, screw, 8, straight pin.
(5) embodiment
A kind of specific embodiment as depicted in figs. 1 and 2, this specific embodiment are mainly used in shear strength test in the automotive brake liner material.It comprises two cutouts 2, a square groove is respectively arranged on two cutouts 2, synthetic square space that holds sample of square groove when two cutouts 2 are fitted on two cutouts 2, and a cutout 2 is higher than another cutout 2, respectively be provided with a guide rail plate 1 outside two cutouts 2, be provided with two needle roller plates 4 and Duo Gen needle roller 3 between each cutout 2 and the guide rail plate 1 that is adjacent, needle roller plate 4 is positioned in the groove of guide rail plate 1, and needle roller plate 4 and guide rail plate 1 are fixing by straight pin 8.Many all rotating being arranged between two needle roller plates 4 of needle roller 3, cutout 2 contacts with needle roller 3.Two guide rail plates 1 connect by screw 7, can adjust two spacings between the guide rail plate 1, and it is fixing with nut 6 that spacing is adjusted the back.
During use, two guide rail plates 1 are placed on the following platen of statics testing machine.Two cutouts, 2 staggered being stuck on the sample 5, two cutout 2 staggered places form the simple shear tangent planes, when the cutout 2 of a higher side and the shearing loading of formation after the last platen of statics testing machine contacts to sample 5.
This specific embodiment can satisfy the interior shear strength tests of multiple friction material such as automotive brake liner material, and can finish various samples cross section simultaneously is that square simple shear is cut test.
