Embodiment Construction

[0010] The device of the present invention and the schematic diagram of each part structure are as Figure 1 ~ Figure 3 As shown, it mainly includes clamping body 1, clamping block 2, fastening bolt 3, stressed block 4, and stressed block fasteners (bolt 5, washer 6 and nut 7) and the like.

[0011] The clamping block is placed in the clamping body, the force-bearing block is fixed on the clamping body with the force-bearing block fastener, and the fastening bolt is used for fastening the clamping block. When working, the plate is placed between the upper clamping body and the lower clamping body, and the clamping block is pushed by tightening the fastening bolts to fasten the plate. By applying force to the force blocks at different positions, the multi-directional tensile and shear load application test can be realized. During the experiment, the force direction of the upper force block, the force direction of the lower force block and the center of gravity of the plate are...

Abstract

The invention discloses a point joint tensile-shear strength testing device capable of applying multi-directional loads, and relates to the multi-directional tensile-shear strength testing experiments of lap-joint point joints for panels. The device comprises a clamp body, a clamping block, a fastening bolt, a stress block and a stress block fastener, wherein the clamping block is arranged in the clamp body, the stress block is fixed on the clamp body by the stress block fastener, the fastening bolt is used for fastening the clamping block, the lap-joint point joint is arranged between an upper clamp body and a lower clamp body during use, and the stress blocks with different angles are force-applied to achieve the multi-directional tensile-shear load-applying testing. The point joint tensile-shear strength testing device has the advantages of convenience in installation and simplicity in operation, and can apply the multi-directional loads.

Description

technical field [0001] The invention relates to a mechanical performance test of lap joints of plates, in particular to a point joint tension and shear strength test device capable of applying multi-directional loads. Background technique [0002] With the development of modern industry, light, high-strength plates such as magnesium alloys, aluminum alloys, and high-strength steels are widely used in the manufacture of equipment in industries such as automobiles and home appliances. The wide application of new materials requires the development of suitable connection methods. At present, there are overlapping point connection methods such as resistance spot welding, friction stir spot welding, self-piercing riveting and TOX stamping connection. However, the existing tensile test and shear test standards cannot comprehensively characterize the mechanical properties of point joints. The test standards for tensile and shear strength can only test the magnitude of a force value...
