Embodiment Construction
[0034] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with its embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0035] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.
[0036] Unless otherwise defined, all technical and scientific t...

Abstract
The invention provides a shear force experiment clamp which comprises a first connecting piece, and one end of the first connecting piece being provided with a first cavity transversely penetrating through the two end faces of the first connecting piece; a connecting assembly, provided with a second cavity transversely penetrating through the two end faces of the connecting assembly; the second cavity being located on one side of the first cavity, one end of the sample being located in the first cavity, and the other end of the sample being located in the second cavity; a first fastening device, arranged on the first connecting piece; and a second fastening device, arranged on the connecting assembly. Through the combination of the first connecting piece and the connecting component, an operator can quickly mount a sample, and through the combination of the first fastening device and the second fastening device, the sample is firmly fixed between the first connecting piece and the connecting component, so that the sample does not rotate, deviate or bend in the loading experiment process. And the effectiveness of experimental data is greatly improved.
Description
technical field [0001] The invention relates to the technical field of engineering testing, in particular to a shear force test fixture. Background technique [0002] With the wide application of aluminum alloy heat insulation profiles, how to ensure the performance of heat insulation profiles to meet the needs of customers has become the focus of common attention of manufacturers and users, so the testing equipment for the performance of aluminum alloy heat insulation profiles is particularly important. Existing technology: The properties of aluminum alloy heat-insulating profiles mainly include longitudinal shear performance, transverse tensile performance, torsion resistance, thermal fatigue performance, high-temperature persistent load transverse tensile performance and high-temperature durable load longitudinal shear performance. At present, except for the longitudinal shear performance under high temperature and long-term load, other performance indicators and test met...
