Abstract
The utility model relates to a test fixture for testing tensile strength, which comprises a loop-shaped clamp body and a tested sample. A bearing rod is fixed on the clamp body; the tested sample is fixedly connected with the clamp body through the bearing rod; an adjusting device for adjusting the position of the tested sample is arranged in the clamp body; a pull traction device is also arranged on the clamp body; as the clamp body is an integral loop-shaped structure and also an overall arc-shaped structure, the rigidity and the deformation resistance of the tensile clamp are improved, thereby improving the reliability and the result accuracy of the tensile test. The adjusting device can effectively prevent the tested sample from being damaged due to incorrect clamping.
Description
Technical field
The utility model relates to anchor clamps, relates in particular to a kind of detection tensile strength test anchor clamps.
Background technology
In the prior art, when the section bar product is carried out Performance Detection, tend to analyze its tensile property, when the tensile property of test section bar, can use stretching clamp, sample is placed the last chuck body and the lower clamp body of stretching clamp, by the two ends that bar load bar is fixed sample respectively of wearing in the chuck body up and down, then when chuck body was moved in the opposite direction up and down, sample then was stretched, and can test its tensile property.
Chuck body of the prior art generally is made up of cross bar that bears pulling force and chuck body, wherein beats or sell to beat by spiral shell between cross bar and the chuck body to be connected.
But, because chuck body of the prior art is the multi-part unitized construction, when pulling force increases gradually, connecting portion between these unitized constructions will bear bigger pulling force, therefore may make this connecting portion generation deformation, thereby reduced the reliability of stretching clamp, also tested section bar has been caused structure, apparent destruction simultaneously.
The utility model content
The technical problems to be solved in the utility model is: a kind of test fixture that detects the transverse tensile strength of tested sample is provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical matters that solves the utility model adopts is: a kind of detection tensile strength test anchor clamps, comprise the chuck body, the tested sample that are back-shaped structure, be fixed with the load bar on the described chuck body, described tested sample is fixedlyed connected with chuck body by the load bar, be provided with the adjusting gear of regulating the tested sample position in the described chuck body, also be provided with the pulling force draw-gear on the described chuck body.
According to another embodiment of the present utility model, a kind of tensile strength test anchor clamps that detect comprise that further described adjusting gear comprises the regulating block of being located between tested sample and the chuck body, the adjuster bar of fixedlying connected with regulating block, and described regulating block is connected with described load bar.
According to another embodiment of the present utility model, a kind of detection tensile strength test anchor clamps comprise that further described adjuster bar is bolt, screw.
According to another embodiment of the present utility model, a kind of tensile strength test anchor clamps that detect further comprise the elastic component that is provided with convenient adjustment distance between described regulating block and the regulating block.
According to another embodiment of the present utility model, a kind of detection tensile strength test anchor clamps comprise that further described pulling force draw-gear is arranged on the tested sample draw direction.
According to another embodiment of the present utility model, a kind of detection tensile strength test anchor clamps comprise that further described tested sample is a heat insulated shape bar of aluminum alloy.
The utility model has solved the defective that exists in the background technology, its beneficial effect is: the back-shaped structure because chuck body is formed in one, be whole camber line contour structures, improve the rigidity of this stretching clamp and the ability of resistance to deformation, thereby improved the reliability of tension test process and result's accuracy; Adjusting gear can prevent effectively that tested sample from damaging sample owing to clamping is improper.
