Description

Cross-shaped section tensile test fixture

Technical Field

The utility model relates to an anchor clamps field, in particular to cross section bar tensile test anchor clamps.

Background

When the workpiece is subjected to a tension test, the workpiece needs to be clamped by using a corresponding clamp. In particular, the cross-shaped profile, in which the two parts are arranged perpendicular to each other, requires to clamp the two parts separately before testing, which is inconvenient. Therefore, there is a need for a novel cross-shaped section tensile testing fixture, which has a simple structure, can clamp two parts of a cross-shaped section conveniently, and can keep stable with the fixture when the two parts of the cross-shaped section are subjected to external forces in opposite directions respectively during testing.

It is seen that improvements and enhancements to the prior art are needed.

SUMMERY OF THE UTILITY MODEL

In view of the foregoing prior art's weak point, an object of the utility model is to provide a cross section bar tensile test anchor clamps aims at solving the complicated technical problem of cross section bar tensile test anchor clamps structure among the prior art.

In order to achieve the purpose, the utility model adopts the following technical proposal:

a cross-shaped section tensile test fixture comprises an upper fixture and a lower fixture, wherein the upper fixture comprises an upper cross rod, two upper drag hooks arranged at the bottom of the upper cross rod, and a clamp handle arranged at the top of the upper cross rod; the lower clamp comprises a lower cross rod, two lower draw hooks arranged at the top of the lower cross rod and a lower clamp handle arranged at the bottom of the lower cross rod.

Furthermore, in the cross-shaped section bar tension test fixture, the two upper draw hooks are the same in shape, and the hook heads of the two upper draw hooks are upward; the two lower drag hooks are the same in shape, and the hook heads of the two lower drag hooks face downwards.

Furthermore, in the cross-shaped section bar tension test fixture, an inclined plane is arranged between the top of each upper draw hook and the upper cross rod, and an inclined plane is arranged between the bottom of each lower draw hook and the lower cross rod.

Furthermore, in the cross-shaped section bar tensile test fixture, the cross sections of the upper clamp handle and the lower clamp handle are rectangular.

Furthermore, in the cross-shaped section bar tension test fixture, an upper clamp handle, an upper cross rod and two upper draw hooks are integrally formed; the lower clamping handle, the lower cross rod and the two lower pull hooks are integrally formed.

Furthermore, in the cross-shaped section bar tensile test fixture, the upper fixture and the lower fixture are respectively made of stainless steel.

Has the advantages that: the utility model provides a cross section bar tensile test anchor clamps compares prior art, the utility model provides a cross section bar tensile test anchor clamps includes anchor clamps and lower anchor clamps, simple structure, convenient to use, and goes up anchor clamps and set up two drag hooks, and lower anchor clamps set up two drag hooks down for cross section bar atress is balanced when the actual test, can with anchor clamps remain stable, guarantees that the test normally goes on.

Detailed Description

The utility model provides a cross section bar tensile test anchor clamps, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the following combination embodiment the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 and 2, the present invention provides a cross-shaped section tensile testing fixture.

A cross-shaped section tensile test fixture comprises an upper fixture and a lower fixture, wherein the upper fixture comprises an upper cross rod 11, two upper drag hooks 12 arranged at the bottom of the upper cross rod, and a clamp handle 13 arranged at the top of the upper cross rod; the lower clamp comprises a lower cross bar 21, two lower draw hooks 22 arranged at the top part of the lower cross bar, and a lower clamp handle 23 arranged at the bottom part of the lower cross bar.

Further, the two upper draw hooks 12 are the same in shape, and the hook heads of the two upper draw hooks are upward 121; the two lower hooks 22 are identical in shape, and the hook heads 221 of the two lower hooks face downwards.

Furthermore, an inclined plane 19 is arranged between the top of each upper draw hook and the upper cross rod, and an inclined plane 29 is arranged between the bottom of each lower draw hook and the lower cross rod.

Further, the upper grip handle 13 and the lower grip handle 23 are rectangular in cross section.

Furthermore, the upper clamping handle, the upper cross rod and the two upper draw hooks are integrally formed; the lower clamping handle, the lower cross rod and the two lower pull hooks are integrally formed.

Further, the upper jig and the lower jig are made of stainless steel, respectively.

In practice, one part of the cross-shaped section bar is lapped in the hook heads of the two upper draw hooks, and the hook heads of the two lower draw hooks are hung on the other part of the cross-shaped section bar. The upper and lower clamp holders are respectively clamped by a clamping mechanism of a tensile tester (not shown in the figure) which applies opposite forces to the upper and lower clamps, thereby performing a tensile test. Because the cross-shaped section is pulled by the two draw hooks and the pull-down hook, the cross-shaped section and the clamp can be relatively stable in the test process.

Can know through above-mentioned analysis, compare prior art, the utility model provides a cross section bar tensile test anchor clamps includes anchor clamps and lower anchor clamps, simple structure, convenient to use, and goes up anchor clamps and set up two and go up the drag hook, and lower anchor clamps set up two drag hooks down for cross section bar atress is balanced during actual test, can with anchor clamps remain stable, guarantees that the test normally goes on.

It is understood that equivalent substitutions or changes can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such changes or substitutions shall fall within the scope of the present invention.
