Universal tool for detecting bending resistance of automobile anti-collision beam

Abstract

The invention relates to the technical field of anti-collision beam testing tools, in particular to a universal tool for detecting the bending resistance of an automobile anti-collision beam. The universal tool comprises a bottom plate, two support roller mounting plate assemblies with adjustable spacing are distributed on the left and right sides of the bottom plate, and support rollers with different diameters can be mounted on each support roller mounting plate assembly. The universal tool further comprises a compression roller body connected with a press machine, and compression roller diameter adjusting pieces arranged on the periphery of the compression roller body to adjust the compression roller body to different diameters. Only one test tool (main body part) needs to be manufactured, and three-point bending tests of anti-collision beams of different forms and sizes can be completed by adjusting the diameter of the compression roller, the diameter of the support rollers and the distance between the support rollers according to needs. Compared with the prior art, remanufacturing and replacement (a main body part) are not needed, the development and manufacturing cost is saved, the test operation efficiency is improved, and very flexible universality is achieved.

Description

technical field [0001] The invention relates to the technical field of anti-collision beam testing tooling, in particular to a universal tooling for detecting the bending resistance of an automobile anti-collision beam. Background technique [0002] The anti-collision beam is a device that absorbs collision energy when the vehicle is hit by a collision. As the first relay point when a car collides, the anti-collision main beam must have sufficient strength. During the development and manufacture of the anti-collision beam, the three-point bending performance testing test to investigate the strength of the anti-collision beam is carried out through special fixed fixtures. , completed on a universal testing machine. According to relevant test standards, the three-point bending performance test of the anti-collision beam is fixed by a special test tool, and after a certain displacement is loaded by the indenter of the universal testing machine at a certain speed, the loading s...

AI Technical Summary

Problems solved by technology

Since each OEM has different test standards for the three-point bending of the beam, the three parameters of the test tooling are also different. The result is that different three-point bending tests may be required for different car companies and even different models. Detect tooling, which is not good for controlling R&D costs and improving test efficiency
