Centering device

Abstract

The invention belongs to the technical field of automobile production and manufacturing, and discloses a centering device. The centering device comprises a positioning mechanism, linear guiding mechanisms, circular arc guiding mechanisms, reset pieces, and clamping jaw mechanisms, wherein the positioning mechanism is configured to penetrate through a hub bearing of a vehicle to be tested; the linear guiding mechanisms are uniformly arranged in the circumferential direction of the positioning mechanism; the circular arc guiding mechanisms are uniformly arranged in the circumferential directionof the positioning mechanism, the positioning mechanism respectively penetrates through centers of the linear guiding mechanisms and centers of the circular arc guiding mechanisms, and the circular arc guiding mechanisms can rotate relative to the positioning mechanism; the reset pieces are connected with the linear guiding mechanisms; the clamping jaw mechanisms respectively penetrate through thelinear guiding mechanisms and the circular arc guiding mechanisms and are in sliding fit with the linear guiding mechanism and the circular arc guiding mechanisms; and the reset pieces are configuredto pull the clamping jaw mechanisms to respectively move along the linear guiding mechanisms and the circular arc guiding mechanisms, so that the bottom of the clamping jaw mechanisms is clamped andconnected with a concave spigot of a hub adapter, and the axis of the hub bearing and the axis of the concave spigot are collinear. With the centering device, accurate and rapid butt-joint installation of the hub adapter and the hub bearing of the vehicle to be tested is realized, and the alignment centering effect is good.

Description

technical field [0001] The invention relates to the technical field of automobile production and manufacturing, in particular to a centering device. Background technique [0002] In the development of automobile products, it is necessary to test the various indicators of the automobile before it can be put on the market, among which the durability of the automobile is an important indicator. The durability test of automobiles is generally realized through the road simulation test. Due to the good repeatability and short test period of the test, it plays an important role in the durability performance assessment of the suspension system. [0003] In the test preparation process, it is necessary to dock the test vehicle with the test equipment. Currently, a special hub adapter is used to connect the test equipment with the test vehicle. During the docking and installation process of the existing 24-channel hub adapter and the hub bearing of the test vehicle, the gap between t...

AI Technical Summary

Problems solved by technology

[0004] It is difficult to ensure the centering effect between the hub adapter and the hub bearing of the test vehicle by manual visual adjustment, the installation accuracy is low, and it is easy to cause bump damage to the test equipment and the test vehicle

In addition, if the distance between the test vehicle and the test equipment is long, it cannot be installed quickly and accurately, and the adjustment time will be long, which will affect the production efficiency
