Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of self-centering fixture of square coupons, including
Mounting plate 1, threaded hole 2, solid post 3, threaded rod 4, handle 5, adjustment barrel 6, bindiny mechanism 7, connecting rod 8, adjusting block 9, sliding slot
10 and specimen holder 11, it is provided with threaded hole 2 on mounting plate 1, and the back side of mounting plate 1 is fixed with solid post 3, the one of threaded rod 4
The side wall across mounting plate 1 is held to extend on handle 5, and the other end of threaded rod 4 is mounted in solid post 3, is pacified on threaded rod 4
Equipped with adjustment barrel 6, the bottom end of connecting rod 8 is connected with each other by bindiny mechanism 7 and adjustment barrel 6, and the other end of connecting rod 8 passes through
Bindiny mechanism 7 and adjusting block 9 are connected with each other, and adjusting block 9 is located at the inside of sliding slot 10, and one end of adjusting block 9 passes through sliding slot 10
It extends on specimen holder 11.
The threaded hole 2 of this example is provided with 4 altogether, and 4 threaded holes 2 are located at the corner of mounting plate 1, can be by pre-
The threaded hole 2 for staying in edge integrally carries out firm installation to the device, is capable of fixing the device in test machine worktable
At center, while it can ensure that sample uniform force.
Solid post 3 and mounting plate 1 form rotating mechanism with threaded rod 4, and threaded rod 4 and adjustment barrel 6 are to be threadedly coupled,
Ensure to control the position of fixture by handle 5 and threaded rod 4.
Bindiny mechanism 7 includes transverse slat 71, vertical pivot 72 and mounting ring 73, mounting ring 73 be mounted on be connected with transverse slat 71 it is perpendicular
