Positioning method of left rear side face vehicle door inner plate assembly

Abstract

The invention relates to a positioning method of a left rear side face vehicle door inner plate assembly. The method includes the following steps of positioning the vehicle door inner plate assembly, positioning an upper frame assembly, positioning an upper nut plate and a lower nut plate, positioning an outer plate supporting plate, and positioning a bumper bar assembly. The process of positioning all parts of an existing left rear side face vehicle door inner plate assembly one by one is changed into the process of sequentially positioning the vehicle door inner plate assembly, the upper frame assembly, the upper nut plate, the lower nut plate, the outer plate supporting plate and the bumper bar assembly, the positioning procedures of the left rear side face vehicle door inner plate assembly are reduced, and production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of vehicle production and manufacturing, relates to the production and manufacture of small and micro cars, and in particular relates to a positioning method for a left rear side door inner panel assembly. Background technique [0002] The left rear side door is tooled through a series of processes of hemming, gluing, and electric welding on the left rear side door inner panel assembly and the left rear side door outer panel. refer to figure 1 , the left rear side door inner panel assembly mainly includes door B-pillar a1, glass lift guide rail a2, upper strip a3, door C-pillar a4, triangular window panel a5, outer panel reinforcement a6, door inner panel b1, lock body reinforcement b2, outer plate support plate e, upper and lower nut plates c, d, anti-collision bar, anti-collision bar front and rear connecting plates f1, f2 and a series of structural parts. The existing production process of the left rear side door...

AI Technical Summary

Problems solved by technology

The existing production process of the left rear side door inner panel assembly is rather cumbersome, mainly through one-to-one assembly of each component of the left rear side door inner panel assembly and then one-time welding of each component, which is easy to exist. There is a problem of large fit gap or tight fit among the components, which is not conducive to the further processing of the left rear side door inner panel assembly and the left rear side door outer panel, resulting in waste products of the left rear side door. In order to improve the process Accuracy, including welding the door B-pillar a1, glass lift guide rail a2, upper strip a3, door C-pillar a4, triangular window panel a5, and outer panel reinforcement plate a6 into the upper frame assembly, and the anti-collision bar and the anti-collision bar The front and rear connecting plates f1 and f2 at both ends of the front and rear are first welded into the anti-collision bar assembly, so that the existing method of positioning each part of the left rear side door inner panel assembly one by one has more processes and is more complicated. It is cumbersome. In order to adapt to the new process of the left rear side door inner panel assembly, a simple and convenient positioning method for the left rear side door inner panel assembly needs to be developed to reduce the positioning process and improve production efficiency.
