Superfine metal composite fiber test fixture

Abstract

The invention belongs to the technical field of composite fiber processing, in particular to a superfine metal composite fiber test fixture which comprises a base, a mounting base and a mounting frame, the mounting frame is of a frame structure and is fastened to the top of the base through bolts in a four-corner fixing mode, the mounting base is located in the center of the bottom of the mountingframe and fixedly connected with the mounting frame, and a through groove is formed in the center of the top of the mounting base; the friction force with the fiber is increased; clamping effect is ensured, a protractor is rotated to a proper angle; the protractor is fixed by rotating a screw cap; therefore, people can adjust the protractor according to the limited swing angle, a movable plate isconvenient to observe and pull to a proper length, the fixed plate is pushed to move along a stop block until a fixed plate is embedded into a clamping groove in the corresponding position, the movable plate is fixed through connection of an external nut and a screw, and people can conveniently observe the linear state of fibers of the movable plate.

technical field [0001] The invention belongs to the technical field of composite fiber processing, and in particular relates to an ultrafine metal composite fiber test fixture. Background technique [0002] Composite fiber is a kind of multi-component fiber, which is a term for man-made fiber varieties. There are two or more polymer fibers that are not mixed on the same fiber section. This fiber is called a composite fiber. It is a physically modified fiber developed in the 1960s. The ultrafine metal composite fiber is doped For fine mixed fibers made of metal, when performing tensile or perpendicularity tests on composite fibers, the fibers need to be clamped by clamps. Most of the clamping methods use one-way or two-way approaching for clamping operations, which leads to There is a deviation between the clamped fiber and the center point, which affects the test effect, and because the fiber is a linear structure, it is difficult to judge whether the fiber is in a straight...

There are two or more polymer fibers that are not mixed on the same fiber section. This fiber is called a composite fiber. It is a physically modified fiber developed in the 1960s. The ultrafine metal composite fiber is doped For fine mixed fibers made of metal, when performing tensile or perpendicularity tests on composite fibers, the fibers need to be clamped by clamps. Most of the clamping methods use one-way or two-way approaching for clamping operations, which leads to There is a deviation between the clamped fiber and the center point, which affects the test effect, and because the fiber is a linear structure, it is difficult to judge whether the fiber is in a straight state when the fiber is bent or stretched obliquely.
