Machining method for door trim of left rear door

Abstract

The invention discloses a machining method for a door trim of a left rear door, which comprises the following steps: firstly, taking a door body, fixing the position of the door body so as to assemble subsequent parts, mounting a door lock on the door body by using a bolt, then mounting a glass lifter on the door body, and mounting glass on the glass lifter. Then the upper assembly is installed on the automobile door body through bolts in a welding mode, then the middle decoration plate assembly part is installed, the decoration strip assembly and the handrail assembly are installed through the bolts and the welding technology, and the upper assembly is composed of a water cutting support, an upper assembly framework and a skin. According to the method, by means of the arrangement mode of installing the automobile door body, when parts of the automobile door body are installed, the installation steps and methods of an automobile door lock, an upper assembly, a middle trim panel assembly, a handrail assembly, a trim strip assembly, a map pocket cover, a side cover plate body, a metal support and the like are described, and therefore the automobile left rear door trim can be conveniently installed and machined.

Description

technical field [0001] The invention relates to the field of door trims, in particular to a method for processing a left rear door trim.

Problems solved by technology

[0003] The evaluation of the planning scheme of the automobile rear door frame processing technology is essentially a multi-feature decision-making problem. The existing methods need to give the importance of each feature. The reasonable importance directly affects the validity of the results, and the processing technology planning of the automobile rear door frame itself has diversity. , complexity, experience and uncertainty are difficult to define a set of appropriate and practical importance. The rear door of a car consists of door outer panel, door inner panel, door Locks and door and window accessories, etc., the inner panel is equipped with glass regulators, door locks and other accessories. Due to the large number of parts on the rear door of the car, a processing method for the left rear door trim is set.
