Description

Stretching clamp

Technical field

The utility model relates to mechanical field, relates in particular to a kind of stretching clamp.

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 clamp 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 clamp body up and down, then when clamp body moved in the opposite direction up and down, sample then was stretched, and can test its tensile property.

Clamp body of the prior art generally is made up of cross bar that bears pulling force and clamp body, wherein is connected by screw or pin between cross bar and the clamp body.

But, because clamp body of the prior art is the multi-part unitized construction, when pulling force increased gradually, the connecting portion between these unitized constructions will bear bigger pulling force, therefore may make this connecting portion generation deformation, thereby reduce the reliability of stretching clamp.

The utility model content

The utility model provides a kind of stretching clamp, reliability that can the tension test process and result's accuracy.

Stretching clamp in the utility model comprises:

Clamp body, and wear bar load bar;

The back-shaped structure that described clamp body is formed in one;

The described bar load bar of wearing is fixed in the described clamp body.

In the utility model, also be provided with gib screw on the described clamp body;

Make the described bar load bar stationkeeping in described clamp body of wearing by regulating described gib screw.

In the utility model, the described bar load bar of wearing is a rectangular structure.

As can be seen from the above technical solutions, the utlity model has following advantage:

1, in the utility model, the back-shaped structure because clamp body is formed in one, be whole camber line contour structures, clamp body itself does not have a plurality of ingredients, so there is not the connecting portion between each ingredient on this clamp body yet, therefore, 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;

2, in the utility model, can adopt back tightening nut to fix between clamp body and the joint, thereby improve the stability of whole stretching clamp;

3, in the utility model, owing to can adopt gib screw to compress to wearing bar load bar, feasible stationkeeping of wearing the sample on the bar load bar, and be rectangular structure owing to wear bar load bar, therefore can prevent that effectively sample deforms in drawing process, thereby improve the extension test effect.

Embodiment

The utility model provides a kind of stretching clamp, is used to improve the reliability of tension test process and result's accuracy.

Stretching clamp in the present embodiment comprises:

Clamp body, and wear bar load bar;

The back-shaped structure that described clamp body is formed in one;

The described bar load bar of wearing is fixed in the described clamp body.

In the utility model, the back-shaped structure because clamp body is formed in one, be whole camber line contour structures, clamp body itself does not have a plurality of ingredients, so there is not the connecting portion between each ingredient on this clamp body yet, therefore, 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.

For ease of understanding, below in conjunction with accompanying drawing the stretching clamp in the present embodiment is described in detail, see also Fig. 1, the stretching clamp in the present embodiment comprises:

Clamp body 101, joint 102 and wear bar load bar 103;

Need to prove that the stretching clamp in the present embodiment is made up of two parts, this two-part structure is identical, and these two parts are subjected to rightabout pulling force respectively can carry out extension test to sample 104.

In the present embodiment, described joint 102 links to each other with described clamp body 101, the described clamp body 101 back-shaped structure that is formed in one, and the described bar load bar 103 of wearing is fixed in the described clamp body.

Wear on the bar load bar 103 sample 104 is arranged, sample 104 in the present embodiment can be band shape or schistose texture, can be around in and wear on the bar load bar 103, the required pulling force of extension test puts on the sample 104, be understandable that concrete pulling force draw-gear can be by latch 106 to provide pulling force.

In the present embodiment,, can between clamp body 101 and joint 102, back tightening nut be set and connect in order to remain on the stability of stretching clamp in the drawing process, thus the stability of raising stretching clamp integral body in drawing process.

In the present embodiment, wear 103 stable being fixed in the clamp body 101 of bar load bar, can on clamp body 101, gib screw be set in order to make, during this gib screw rotation, can be so that wear 103 stable being fixed in the clamp body 101 of bar load bar.

This gib screw can be provided with two, lays respectively at the both sides of joint 102.

If in drawing process, sample 104 deforms or slides, and then can influence precision of test result, then in the present embodiment, wear bar load bar 103 and be rectangular structure, can make sample 104 in drawing process, can not slide, and can prevent effectively that sample 104 from deforming.

The bar load bar 103 of wearing in the present embodiment can be for being applicable to the special material of aluminium section bar, and this special material makes that wearing bar load bar 103 is difficult for deforming.

Stretching clamp physical dimension in the present embodiment can be mated with high-low temperature chamber, optimal design, reaches normal temperature and high low temperature is general.

Need to prove, stretching clamp in the present embodiment goes for aluminum alloy building section-heat insulation section and metallic insulation section bar, be understandable that the stretching clamp in the present embodiment goes for the section bar of other types equally, particular type does not limit herein.

More than a kind of stretching clamp provided by the utility model is described in detail, for one of ordinary skill in the art, according to thought of the present utility model, part in specific embodiments and applications all can change, in sum, this description should not be construed as restriction of the present utility model.
