Fig. 1 is the using state figure of an embodiment of testing machine in the utility model;
Fig. 2 is connecting-piece structure schematic diagram in Fig. 1;
Fig. 3 is the left view of Fig. 2.
Embodiment
The embodiment of testing machine is as shown in Fig. 1 ~ 3: on comprising, lower pull head, on, lower pull head is all connected with bolt shearing test clamp 1 and lower bolt shearing test clamp 8, on, the structure of lower bolt shearing test clamp is identical, now only the structure of upper bolt shearing test clamp is described in detail, upper bolt shearing test clamp 1 comprises web member and plate face bearing of trend that split arranges perpendicular to the shear plate 3 of left and right directions, web member is provided with the testing machine syndeton for being connected with the corresponding pull head of testing machine, in the present embodiment, testing machine syndeton is the connecting screw rod 9 that axis extends along the vertical direction, bolt shearing test clamp also comprises the shear plate syndeton for being connected to by shear plate in use on web member, shear plate syndeton comprise be shaped in testing machine syndeton lower end plate face bearing of trend perpendicular to the web joint 4 of left and right directions, center line on testing machine syndeton left and right directions is positioned on the right panel face 11 of web joint, thickness on web joint left and right directions is identical with the half of testing machine syndeton left and right directions thickness, that is larger section transitions is not had between the left surface of testing machine syndeton and the left plate face of web joint, shear plate syndeton also comprises the connecting hole 10 that the axis be opened on web joint extends in left-right direction, by coupling bolt 5(or connection pin during use) shear plate 3 is fixed on web joint 4, the left plate face of shear plate and the right panel of web joint are put in the face of being sticked.Shear plate offers the bolt penetration hole that the corresponding bolt to be tested of confession that two axis extend in left-right direction installs, two bolt penetration hole are between the upper and lower every setting.
During use, by connecting screw rod, web member is connected on corresponding pull head, by the left plate of shear plate in the face of being attached to the right panel face of web joint, by coupling bolt, shear plate is fixed on web joint, bolt 6,7 to be tested is installed in corresponding bolt penetration hole, by upper and lower pull head, pulling force is applied to bolt shearing test clamp and shear test is carried out to bolt to be tested.Because shear plate and web member split are arranged, so web member and shear plate can select different materials, web member can select the higher material of strength of joint to make, to ensure the strength of joint between web member with corresponding pull head, shear plate can select the material same with the actual shearing environment facies of bolt to be tested to make, simulate the shear test of more pressing close to bolt environment for use with this, ensure the reliable results of shear test; Owing to shearing screw to be tested by shear plate, so the thickness of web joint is no longer restricted, the thickness of web joint can be identical with the half of the thickness of testing machine syndeton, so just can avoid the problem of stress concentration that the sectional dimension transition between testing machine syndeton left surface and web joint left surface causes more greatly and easily, the strength of joint between web joint and shear plate then can be ensured by the number of coupling bolt.
In other embodiment of this testing machine: the number of bolt penetration hole can also be arranged as required, such as one, three or other number; Web joint also can be connected in testing machine syndeton by other web joint syndeton, such as is hanging structure, and shear plate is provided with hook, and web joint syndeton comprises the hanging groove be arranged in connection; The thickness of web joint can also be greater than the half of the thickness of testing machine syndeton; Testing machine syndeton suitably can also adjust according to the syndeton of upper and lower pull head, such as when the syndeton on upper and lower pull head is oat tail groove structure, testing machine syndeton can be the dovetail guide structure coordinated with dovetail groove.
The embodiment of bolt shearing test clamp is as shown in 1 ~ 3: the structure of bolt shearing test clamp is identical with the upper bolt shearing test clamp described in above-mentioned each testing machine embodiment, is not described in detail in this.
