Abstract

The invention discloses a centering and fastening component for assembling a front cover of an automobile. The centering and fastening component comprises a front cover assembling and fastening device and a front cover centering device, wherein the front cover assembling and fastening device comprises a hollow casing, a cover body, a protective cap, a force application gear, a force transferring gear, a stressing gear and a pipette tip; the force application gear, the force transferring gear and the stressing gear are mounted in the hollow casing, and are sequentially meshed; deep groove ball bearings are separately arranged on the upper ends and the lower ends of the gears; a rotating shaft is connected to the lower end of the force application gear, and penetrates through a through hole in the casing to be connected with an extension rod; the front cover centering device comprises an upper plate, a lower plate, a fixing plate, elastic cylindrical pins, a positioning pin and an aligning pin, wherein the elastic cylindrical pins and the aligning pin penetrate through the lower plate and the upper plate; and two deep groove ball bearings are arranged on a positioning plate, and the positioning pin is clamped by the two deep groove ball bearings. The centering and fastening component for assembling the front cover of the automobile disclosed by the invention can be used for adjusting the precision between the front cover and an automobile body when the front cover is assembled, so that the front cover is accurately matched with a front cabin of the automobile, the stability and the precision for assembling the front cover are guaranteed, and the quality and the security coefficient of products are improved.

Description

technical field [0001] The invention belongs to the field of automobile front cover assembling equipment, and in particular relates to a centering fastener for installing a front cover of an automobile when the front cover is assembled. Background technique [0002] A car is an organic combination of various parts, and the last process of car production must be assembly. Technical requirements for automobile assembly: the integrity of the assembly, there must be no missing or under-installed phenomena, and do not ignore small parts; Solidity. For a high-speed moving object in the air, the air resistance and turbulence generated by the airflow around the moving object will directly affect the trajectory and speed of the movement. The shape of the hood can effectively adjust the flow direction of the air relative to the movement of the car and the impact on the car. The resulting obstruction force reduces the impact of airflow on the car. The appearance of the hood is basic...
