Bending stress detection device for inspecting composite material automotive leaf spring product

Abstract

The invention discloses a bending stress detection device for inspecting a composite material automotive leaf spring product. The bending stress detection device comprises a main tank body, wherein adetection bin is welded in the main tank body, and two hydraulic cylinders and two stepping motors are arranged on the outer surface of the upper end of the detection bin; clamping seats are welded totwo sides of the inner surface of the detection bin, preserved screw holes are formed in the upper and lower ends in the detection bin in a penetration manner, and hydraulic columns penetrate throughthe inside of the hydraulic cylinders. According to the bending stress detection device, a to-be-detected composite leaf spring can be fixed in multiple directions, the adverse influence caused by unsteady fixation to the detection can be prevented, and the to-be-detected composite leaf spring can be sectionally detected, so that the accuracy of a detection result can be improved; and the operation environment of the composite leaf spring on an automotive can be relatively truly simulated, so that the detection result is relatively close to a real result.

Description

technical field [0001] The invention relates to the field of leaf spring quality inspection work, in particular to a bending stress detection device for inspection of composite material automobile leaf spring products. Background technique [0002] The leaf spring quality inspection is the process of carrying out various indicators of the leaf spring. The indicators mentioned here include size, flatness, arc height, bending stress and pressure resistance, etc. The existing composite material automobile leaf spring product inspection The device cannot perform bending stress detection on the composite leaf spring more conveniently, and when the composite leaf spring works on the vehicle for a long time, it will generate a certain amount of heat, and the composite leaf spring will bear the bending load in the upper and lower directions. Some composite material automobile leaf spring product testing devices cannot simulate the above-mentioned working conditions. Even if the resu...

[0002] The leaf spring quality inspection is the process of carrying out various indicators of the leaf spring. The indicators mentioned here include size, flatness, arc height, bending stress and pressure resistance, etc. The existing composite material automobile leaf spring product inspection The device cannot perform bending stress detection on the composite leaf spring more conveniently, and when the composite leaf spring works on the vehicle for a long time, it will generate a certain amount of heat, and the composite leaf spring will bear the bending load in the upper and lower directions. Some composite material automobile leaf spring product testing devices cannot simulate the above-mentioned working conditions. Even if the results can be detected, they are not realistic enough, and the composite leaf spring cannot be tested in sections, which will reduce the accuracy of the test results. , we propose a bending stress detection device for inspection of composite automobile leaf spring products
