How to install the sliding door guide rail of the body

Abstract

The invention discloses a mounting method of a sliding door guide rail of a car body, which comprises the following steps of: step 1, welding a side inner panel and an upper guide rail to form a firstassembly; 2, welding a side wall reinforcing plate and a side wall support plate to form a second assembly; 3, welding the first assembly and the second assembly to form a third assembly; 4, weldingthe side wall outer plate and the third assembly; 5, welding the outer side wall plate and the top cover; The side inner panel has a center portion, one side of the center portion forms an extension portion extending upward, and the other side forms an inclined portion extending obliquely downward, the inclined portion and the center portion form a bottom accommodating cavity, and a guide rail iswelded in the accommodating cavity. The mounting method of the sliding door guide rail of the vehicle body of the invention only needs to change the plate of the corresponding part in the replacementof the size of the vehicle, avoids the problem of replacing all the plates, improves the efficiency and reduces the cost by distributing welding and the mechanism of each plate.

Description

technical field [0001] The invention relates to an installation method of a slide door guide rail of a vehicle body. Background technique [0002] With the continuous development of automobile technology and the continuous growth of automobile enterprises, the initial model is gradually enriched into products with the same platform or products with the same family shape and use. For example, after a model is successfully developed, there may be replacement products, annual products, upgraded high-end versions, and so on. [0003] For body-in-white, replacement products with the same size of the whole vehicle generally only need to develop some special parts, but when the size of the whole vehicle changes, the body-in-white needs to be redesigned. When the size of the vehicle changes, it is difficult to realize the body-in-white through the development of some special parts. The assembly of longitudinal beams, engine cabins, top covers, side panels and even floors must be re...
