Description

Technical Field

[0001] The utility model relates to the technical field of material detection fixtures, in particular to an in-situ tensile torsion test fixture. Background Art

[0002] Ceramic fiber is referred to as ceramic fiber felt. It is a fibrous material made by melting high-temperature resistant refractory materials (such as coke) through electric arc and then blowing compressed air. It is also called ceramic fiber cotton. Ceramic fiber has strong high-temperature resistance and can withstand temperatures up to 1200 degrees Celsius.

[0003] The in-situ tensile torsion test is a mechanical test on the material. When the existing in-situ tensile torsion test device is used, the two ends of the material are clamped and fixed, and the material is tested by stretching or torsion. However, when the existing test device is in use, when the tensile or torsion force is large, the two ends of the material are easy to break free from the clamp, and at the same time, the two ends of the material may break and detach from the clamp, causing the test to be interrupted and difficult to clamp stably.

[0004] To this end, we propose an in-situ tensile-torsion test fixture. Utility Model Content

[0005] The utility model mainly solves the above technical problems and provides an in-situ tensile torsion test fixture.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an in-situ tensile torsion test fixture, comprising a base, a left-right symmetrical fixed plate fixedly installed on the top surface of the base, a plurality of fixed rods fixedly installed between two groups of fixed plates, two groups of sliding plates slidably installed on the plurality of fixed rods, a threaded rod rotatably installed between the two groups of fixed plates, a threaded rod is provided on the threaded rod, the threads on the threaded rod are arranged oppositely on the left and right, the sliding plate is threadedly connected with the threaded rod, the two groups of sliding plates are respectively distributed on the left and right sides of the threaded rod, a driving motor is provided on the outer side of the fixed plate, the output end of the driving motor is fixedly connected to the threaded rod through a rotating shaft, and the driving motor is started to control the threaded rod to rotate forward or reverse, so that the threaded rod controls the two groups of sliding plates to slide closer to each other or slide away from each other;

[0007] A connection disk is fixedly installed on the inner side of one group of sliding plates, and a connection disk is movably installed on the inner side of another group of sliding plates through a rotating shaft. The two groups of connection disks are distributed correspondingly on the left and right, and a clamp assembly for fixing the material to be tested is arranged on the connection disk.

[0008] Preferably, the clamp assembly comprises a connecting frame, which is fixedly mounted on a side of the two groups of connecting plates close to each other, and the two groups of connecting frames are distributed in left and right mirror images.

[0009] Preferably, an eccentric extrusion roller is rotatably mounted inside the connecting frame, and a handle plate is rotatably mounted on the outer side of the connecting frame. The handle plate is fixed to the eccentric extrusion roller via a rotating shaft, and the rotation of the eccentric extrusion roller is controlled by rotating the handle plate.

[0010] Preferably, a plurality of groups of outer fixing needles are fixedly installed at equal intervals on the outer side surface of the connecting frame, and a plurality of groups of inner fixing needles are fixedly installed at equal intervals on the inner wall surface of the connecting frame.

[0011] Preferably, the plurality of groups of outer fixing needles and the plurality of groups of inner fixing needles are distributed in a left-right mirror image manner.

[0012] Beneficial Effects

[0013] The utility model provides an in-situ tensile torsion test fixture, which has the following beneficial effects:

[0014] (1) When using the in-situ tensile torsion test fixture, the material to be tested is set between two groups of fixture components. A plurality of through holes are opened near the two ends of the material to be tested. The two ends of the material to be tested are respectively wrapped around the two groups of connecting frames. At this time, the material to be tested will be sleeved on the plurality of outer fixing needles and inner fixing needles through the through holes. The outer fixing needles and inner fixing needles can prevent the material to be tested from accidentally detaching from the fixture component. By rotating the handle plate, the handle plate drives the eccentric extrusion roller to rotate. The outer circle of the eccentric extrusion roller will gradually approach the inner wall surface of the connecting frame. The two ends of the material to be tested are reinforced by the extrusion force of the eccentric extrusion roller, so that the material to be tested is firmly distributed between the two groups of fixture components, thereby achieving the effect of preventing the test material from accidentally detaching from the fixture.

[0015] (2) In the in-situ tensile torsion test fixture, after the material is fixed between the two sets of components, the two sets of sliding plates are controlled to move away from each other by the threaded rod, so as to detect the tensile strength of the material. The driving mechanism controls the rotation of the movable connecting disk, so that the connecting disk drives the material to twist, thereby detecting the torsional strength performance of the material, achieving the effect of testing the tensile strength and torsional strength of the material.
