Abstract

The invention relates to a press fit fixing device for a vehicle lamp lampshade and a lamp shell. A rack is provided with a frame-shaped bracket, a worktable and a top plate; a lamp positioning mechanism comprises a lower template, lower supporting seats, an upper template and an upper supporting seat; each lower supporting seat is provided with a supporting surface and a nail injecting hole; rotating mechanisms arranged on the upper template and the lower template are connected with the worktable and a movable press fit platform plate; guide limiting seats are arranged on the upper template and the lower template on both sides of the rotating mechanisms; a linear bearing of a press fit mechanism is arranged on the movable press fit platform plate; guide posts arranged on the worktable and the top plate are matched with the linear bearing; a compression cylinder arranged on the top plate is connected with the upper template through the movable press fit platform plate; limiting cylinders are arranged on the movable press fit platform plate and the worktable; and limiting blocks correspond to the guide limiting seat at the bottom of the lower template and the guide limiting seat on the top of the upper template respectively. The press fit fixing device has the characteristics of lightness and convenience as well as safety in operating and capabilities of improving assembling quality and increasing production efficiency.

Description

technical field [0001] The invention relates to a pressing and fixing device for a lampshade and a lamp shell of a vehicle lamp, belonging to the technical field of motor vehicle lamp manufacturing. Background technique [0002] The headlights of motor vehicles are installed on both sides of the head of the car for the illumination of roads at night. The headlight is mainly composed of three parts: the light source, the reflector and the light distribution mirror. The light source, the reflector and the light distribution mirror are all installed between the lamp housing and the lampshade. The service life of the headlight and the brightness of the light beam during use, so after crimping the glued lamp housing and lamp shade, use a Martin gun to fix the nails along the lamp housing into the periphery of the lamp shade. [0003] At present, the assembly of the lamp housing and the lamp shade of the automobile lamp is mostly manually assembled. Since the glue groove on the l...

Problems solved by technology

[0003] At present, the assembly of the lamp housing and the lampshade of the car lamp is mostly manually assembled. Since the glue groove on the lamp housing and the lamp shade have a large gap, the gap between the lamp housing and the lamp shade of each lamp during the installation process It cannot be controlled to the best state, which makes it difficult to control the height of the combination of the lamp shade and the lamp housing, which will lead to poor matching between the lamp and the automobile sheet metal and bumper, and there will be few qualified products. On the one hand, it will affect The assembly of car lights and car body affects the appearance of the car at the same time, and the consistency of each batch of car lights cannot be guaranteed

On the other hand, manual assembly is adopted, the operators are very laborious, the labor intensity is high, and the production efficiency is low.
