Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0053]It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0054] In addition, if there are descriptions involving "first", "second" and s...

Abstract

The invention discloses an automobile body multi-axis local rigidity test device, which comprises a mounting bottom plate, a sliding table mechanism, a first adjusting structure and a loading device, and is characterized in that the mounting bottom plate extends in the left-right direction; the sliding table mechanism is arranged on the mounting bottom plate in a sliding mode in the left-right direction, and a working platform is arranged at the upper end of the sliding table mechanism. The first adjusting structure comprises a first stand column, a second stand column and a driving structure, the first stand column extends in the up-down direction and is mounted on the mounting platform, the second stand column extends in the front-back direction and is movably mounted on the first stand column in the front-back direction, and the driving structure is mounted on the second stand column in the front-back direction; the second stand column is arranged on the base and can rotate with the first stand column as a rotating shaft, and the driving structure drives the second stand column to move in the front-back direction and drives the second stand column to move in the up-down direction along the first stand column. The invention aims to solve the problem that an existing hydraulic durable rack cannot carry out local rigidity tests on automobile bodies of various types of automobiles.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to a multi-axis local stiffness testing device for an automobile body. Background technique [0002] At present, there is no special test device for local stiffness of commercial vehicle bodies in China. Most manufacturers can only use general hydraulic durable benches for local stiffness tests of commercial vehicle bodies. Because the accuracy and stability of hydraulic durable benches cannot be well guaranteed during the loading process, And poor versatility. Contents of the invention [0003] The main purpose of the present invention is to provide a multi-axis local stiffness test device for automobile bodies, aiming to solve the problem that the existing hydraulic durable bench cannot perform local stiffness tests on automobile bodies of various models. [0004] In order to achieve the above object, a kind of automobile body multi-axis local stiffness test device prop...
