Abstract
The utility model relates to a test clamp for detecting shear strength, which comprises a fixed seat. A rigid supporting board is connected onto the fixed seat through a supporting rod. A briquette assembly is arranged between the fixed seat and the rigid supporting board in the longitudinal direction. A sample to be tested is arranged in the middle of the briquette assembly. The test clamp for detecting the shear strength can effectively avoid rotation or shifting of the sample to be tested when being stressed by shear force and the shear force can be directly transmitted to the sample to be tested through the rigid supporting board. The test clamp for detecting the shear strength has simple structure, can ensure evenness of shear force loading and avoids direct contact of the shear force and the sample to be tested.
Description
Technical field
The utility model relates to a kind of pick-up unit, relates in particular to a kind of test fixture that detects shear resistance.
Background technology
Shear test can be measured the drag performance of material under the shearing force effect, is one of fundamental test method of mechanical property of materials test, is mainly used in test and bears the part and the material of shear-type load.Though it is all multifactor whether shear test successfully depends on, anchor clamps wherein are that sill also is one of most important equipment.
In the process of test, along with the shearing force of testing constantly increases, the acting force that anchor clamps are subjected to is also increasing, occurs more problem easily at present:
1, originally after long-time use, loosening easily or offset causes shearing force to act on the material of test vertically, uniformly to anchor clamps, influences test result; 2, test material rotates and is offset when loading easily usually, has influenced test result equally; 3, for some special test materials, measured material directly will be added shearing force and be loaded on the test material, can influence the quality of test material itself like this; 4, existing anchor clamps often all are anchor clamps specific on each testing table, and suitable field is narrower.
The utility model content
The technical problems to be solved in the utility model is: the test fixture that a kind of detection shear resistance simple in structure, that rotate or be offset when effectively preventing tested sample loading shearing force 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 test fixture that detects shear resistance, comprise firm banking, be connected with the non-yielding prop plate by support bar on the described firm banking, between described firm banking and the non-yielding prop plate, longitudinal direction is provided with the briquetting assembly, and tested sample is arranged in the middle of the described briquetting assembly.
According to another embodiment of the present utility model, a kind of test fixture that detects shear resistance further comprises on the longitudinal direction of described support bar and is equipped with elastic component.
According to another embodiment of the present utility model, a kind of test fixture that detects shear resistance comprises that further described elastic component is a spring assembly.
According to another embodiment of the present utility model, a kind of test fixture that detects shear resistance comprises that further described briquetting assembly comprises upper holder block, lower lock block, and described upper holder block is connected with described non-yielding prop plate, and described lower lock block is connected with described firm banking.
