Positioning method of left front side car door inner panel assembly

Abstract

The invention relates to a positioning method of a left front side car door inner panel assembly. The positioning method of the left front side car door inner panel assembly comprises the following steps of positioning the car door inner panel assembly; positioning an upper coaming assembly; positioning an upper nut plate and a lower nut plate; positioning an outer panel support plate; positioning a bumper bar assembly. The existing process of positioning all parts of the left front side car door inner panel assembly one by one is changed to be the process of sequentially positioning the car door inner panel assembly, the upper coaming assembly, the upper nut plate, the lower nut plate, the outer panel support plate and the bumper bar assembly, so that the positioning process of the left front side car door inner panel assembly is reduced, and the production efficiency is improved.

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
