Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision beam detection, in particular to an aluminum alloy anti-collision beam detection mechanism for automobiles. Background Art

[0002] The anti-collision beam is a device that absorbs collision energy when a vehicle is hit. As the first relay point when a car collides, the anti-collision main beam must have sufficient strength. When the anti-collision beam is developed and manufactured, the three-point bending performance test to examine the strength of the anti-collision beam is completed on a universal testing machine through a special fixed fixture clamp. According to relevant test standards, the three-point bending performance test of the anti-collision beam is completed by fixing it with a special test fixture, and then loading a certain displacement at a certain speed by the universal testing machine pressure head, and then recording and evaluating the loading state and maximum bending force of the anti-collision beam.

[0003] China Patent Network discloses a universal tooling for testing the bending performance of automobile anti-collision beams (publication number: CN112649308A), including a bottom plate, on which two support roller mounting plate assemblies with adjustable spacing are distributed on the left and right sides of the bottom plate, and support rollers of different diameters can be installed on each support roller mounting plate assembly; it also includes a roller body connected to the press, and a roller diameter adjustment sheet arranged on the periphery of the roller body to adjust the different diameters of the roller body. The test tooling (main part) of the present invention only needs to be made in one pair, and by adjusting the three elements of the roller diameter, the support roller diameter and the support roller spacing as needed, the three-point bending test of anti-collision beams of different forms and sizes can be completed; compared with the prior art, the present invention does not need to be remade and replaced (main part), saving development and manufacturing costs, improving test operation efficiency, and having very flexible versatility.

[0004] Although the above technology can test the three-point bending resistance of anti-collision beams of different forms and sizes, the anti-collision beam is placed directly on the support stick during the test and is not fixed. When there is a slight tilt when placed, uneven force will occur when it is hit, affecting the test results. At the same time, there is a risk of the anti-collision beam sliding off the support stick when a collision occurs, which poses a safety hazard. Therefore, there is room for improvement.
