Background

The metal mechanical property test method is one of important means for detecting and evaluating the quality of metallurgical products, wherein the tensile test is the most widely applied mechanical property test method. The elastic deformation, plastic deformation, fracture and other stages in the test truly reflect the whole process of resisting the external force of the material. It is simple and easy to implement, and the sample is easy to prepare. The basic mechanical property indexes of the material, such as the indexes of elastic modulus, Poisson's ratio, yield strength, tensile strength, reduction of area, elongation after fracture and the like, can be obtained through a tensile test, and are important parameters for reflecting the mechanical property of the metal material. And the elongation after fracture is completely obtained by calculation after measuring the post-fracture gauge length by a detector, and the elongation index is directly influenced by the post-fracture gauge length measurement value.

In actual operation, tensile test is because of the terminal surface is irregular after the stretch-breaking, two sections after the break are very difficult to compare and recover, and the testing personnel need grab the steady test bar with one hand when one man's operation, grab slide caliper with one hand and measure, and the sample often drops in this in-process, phenomenons such as aversion, and is difficult fixed, causes the gauge length inaccurate after the break that surveyed, influences the testing result. The utility model provides a stretch out back gauge length detection auxiliary device absolutely, it is inconvenient to have solved the single-hand operation of testing personnel, causes the measured data deviation to look into, influences the testing result.

SUMMERY OF THE UTILITY MODEL

In order to overcome prior art not enough, the utility model provides a tensile detection auxiliary device can solve in actual operation, and tensile test is irregular because of the terminal surface after breaking, and two sections after breaking are hardly compared and are recovered, must grab steady test stick on one hand during the one-man operation of measurement personnel, grabs vernier caliper on one hand and measures, and the sample often drops in this in-process, phenomenons such as aversion, and is difficult fixed, causes the disconnected back gauge length inaccurate, influences the testing result. The utility model provides a stretch out back gauge length detection auxiliary device absolutely, it is inconvenient to have solved the single-hand operation of testing personnel, causes the measured data deviation to look into, influences the technical problem of testing result.

In order to solve the technical problem, the utility model provides a following technical scheme: tensile detection auxiliary device, including the body, the body top is seted up decurrent cavity of placing, place the cavity centre and set up rather than the support chamber that link up each other.

As an optimized technical scheme of the utility model, place and to have placed the test rod in the cavity, the test rod fracture portion is placed in supporting the intracavity.

As an optimized technical scheme of the utility model, the bottom embedding of support intracavity portion has the silica gel pad.

As an optimal technical scheme of the utility model, silica gel pad inner wall radian is unanimous with support chamber bottom radian.

As an optimal technical scheme of the utility model, silica gel pad length is unanimous with supporting chamber length.

Compared with the prior art, the utility model discloses the beneficial effect that can reach is:

1. the test bar after being broken is placed in the placing cavity, the broken parts of the test bar are aligned, a detector can measure the mark distance of the test bar by holding a vernier caliper, the test bar can be used for assisting the test bar with any specification from phi 10 to phi 15 directly, the test bar before being broken can be placed in the placing cavity, and the detector can assist the mark distance marking by holding hot stamping;

2. through supporting chamber bottom embedding silica gel pad, when the handheld slide caliper of measurement personnel measured the test bar, slide caliper and body surface contact caused slight rocking to the body, also can not make the test bar fracture portion rock, further promoted measurement personnel measured data's accuracy.
