Dimming component and heat resisting sheet combined assembling device for automobile front fog lamp

Abstract

The invention relates to a dimming component and heat resisting sheet combined assembling device for an automobile front fog lamp. A lower guide post, a first support seat, a first limiting seat and a second limiting seat are mounted on the bottom plate of a lower die component, and a third limiting seat and a fourth limiting seat are arranged on the first support seat; an upper guide post, a rear limiting plate and a sliding table cylinder are mounted on the top plate of an upper die component, the rear limiting plate is mounted on a rear side of the top plate, a positioning groove for limiting a heat resisting sheet on the rear limiting plate is formed in the front part of the second limiting seat, the rear limiting plate is provided with at least two magnetic blocks for adsorbing the heat resisting sheet, in the position of the positioning groove, a U-shaped support is mounted on the moving piece of a sliding table cylinder, a shift lever for stirring and limiting a dimming rod is arranged on the rear side of the U-shaped support, a cylinder is mounted on the mounting seat at the front part of the U-shaped support, an absorbing seat used for adsorbing a dimming screw cap is mounted on the piston rod of the cylinder, and a vacuum-pumping adsorbing cavity is formed in the absorbing seat. The dimming component and heat resisting sheet combined assembly device provided by the invention has a reasonable structure and can improve the assembling efficiency and precision.

Description

technical field [0001] The invention relates to a dimming assembly and a heat insulating plate assembly device of an automobile front fog lamp, and belongs to the technical field of motor vehicle lamp manufacturing. Background technique [0002] The traditional motor vehicle front fog lamp is mainly composed of a lamp holder, a light distribution mirror, a reflector and a light bulb. The light distribution mirror and the reflector are respectively installed at the front and rear of the lamp holder. The reflectors are connected to form a catadioptric system to obtain the required light distribution of the front fog lights. In severe weather conditions such as fog, snow and heavy rain, or when driving in a smoky environment, in order to illuminate the road ahead, To ensure driving safety, front fog lights must be used for lighting. However, since the front fog lights emit a lot of heat when they are lit, and the structure of the conventional front fog lights is relatively com...

AI Technical Summary

Problems solved by technology

However, when the above-mentioned dimming components and heat shields are combined and assembled, on the one hand, the lamp holder needs to be positioned and fixed twice, and the assembly standards are different, so it is difficult to improve the assembly accuracy, and the assembly of the two processes also takes a certain amount of auxiliary time, which increases the assembly time. time

On the other hand, manual assisted assembly is not only labor-intensive, but also low in assembly efficiency. Especially during the press-in process of the dimming nut, the assembly position often deviates, making it difficult for the axis of the dimming rod and the dimming nut to be coaxial. Two or more press-fits are required, which reduces the assembly accuracy, and even causes damage to the installation of the dimming nut or the lamp holder, resulting in great differences in the front fog light type, and the assembly pass rate is not high
