Positioning method of left front side door inner panel assembly

Abstract

The invention relates to a positioning method for an inner panel assembly of a left front side vehicle door. The method includes the following steps: positioning the inner panel assembly of the car door; positioning the upper panel assembly; positioning the upper and lower nut plates; positioning the outer panel support plate; Change the existing process of positioning each part of the left front side door inner panel assembly one by one to the process of positioning the inner door panel assembly, the upper wall panel assembly, the upper and lower nut plates, the outer panel support plate, and the anti-collision bar assembly. Sequential positioning reduces the positioning process of the left front side door inner panel assembly and improves production efficiency.

Description

technical field [0001] The invention belongs to the field of vehicle production and manufacture, relates to the production and manufacture of small and miniature automobiles, in particular to a positioning method for a left front side door inner panel assembly. Background technique [0002] The left front side door is tooled through a series of processes of wrapping, gluing, and electric welding on the left front side door inner panel assembly and the left front side door outer panel. refer to figure 1 , the left front door inner panel assembly mainly includes the rearview mirror mounting plate a1, the door B-pillar a2, the glass lift guide rail a3, the outer panel reinforcement plate a4, the upper strip a5, the anti-collision bar and the front and rear ends of the anti-collision bar A series of structural parts such as front and rear connecting plates f1, f2, door inner panel assembly b, upper and lower nut plates c, d, outer plate support plate e, etc. The existing produ...

AI Technical Summary

Problems solved by technology

The existing production process of the left front side door inner panel assembly is relatively cumbersome. It mainly assembles each part of the left front side door inner panel assembly in one-to-one correspondence, and then performs one-time welding of each part, which is easy to exist. There is a large fit gap or the tight fit between the parts, which is not conducive to the further processing of the left front side door inner panel assembly and the left front side door outer panel, resulting in waste products of the left front side door. In order to improve the process accuracy, some Mirror mounting plate a1, door B-pillar a2, glass lift guide rail a3, outer panel reinforcement plate a4, and upper strip a5 are first welded into the upper panel assembly, and the anti-collision bar and the front and rear parts located at the front and rear ends of the anti-collision bar The rear connecting plates f1 and f2 are first welded into the anti-collision bar assembly, so that the existing method of positioning each component of the left front side door inner panel assembly one by one has many procedures and is relatively cumbersome. The new technology of the panel assembly needs to correspond to a set of simple and convenient positioning methods for the inner panel assembly of the left front side door, reducing the positioning process, so as to improve production efficiency
