Abstract
The invention provides a lap joint process of two outer skins of car body. Firstly lap joint position of two outer skins is subject to spot welding, then lap seam is subject to glue injection and glue collection, and finally the entire car body assembly is subject to surface paint spraying procedure. By adopting the technical scheme of the invention, brazing, polishing and dust scraping steps in the traditional lap joint process are substituted, process is greatly simplified, quality is easy to control, one-time pass rate of product is improved by about 8%, and single car cost is also reduced.
Description
Technical field
The invention belongs to Automobile manufacturing technology field, specifically, relate to the lap joint process between auto body two exterior skins.
Background technology
For a long time, in the lap joint process between auto body two exterior skins (as A column exterior skin and top cover, middle threshold exterior skin hypomere and gusset exterior skin front and rear sections), people are in order to pursue intensity and the overall appearance effect that overlaps between vehicle body two exterior skins, usually adopted following welding and coating process, mainly contained following process: lap-joint's soldering (brazing) → polishing → Puttying → red ash → polishing of polishing → scrape.Because there is arc modeling in most vehicle body exterior skins, in the process of polishing, be difficult to reach the ideal effect of uniformity, technology and experience to the workman require height, are prone to more defective, and be not full as the soldering joint filling, it is bad to polish, grey scar, trachoma etc. occur, and it is higher the frequency of above defective to occur, the quality control difficulty is big, the amount of reprocessing is big, causes single vehicle cost higher.
Summary of the invention
The purpose of this invention is to provide the lap joint process between a kind of auto body two exterior skins, the operation of this technology is simplified, and quality is controlled easily, helps to reduce the bicycle manufacturing cost.
For achieving the above object, the invention provides the lap joint process between a kind of auto body two exterior skins, be included in two exterior skin overlapping parts and adopt welding and coating process successively, wherein: in the welding sequence, be that the overlapping part between two exterior skins is carried out spot welding; In the coating process, be behind the electrophoretic primer lapped seam between two exterior skins to be carried out injecting glue and received the glue processing.
The present invention compares with traditional handicraft, has two big advantages:
One, replace soldering with spot welding, on this station, no longer use argon welder with point welder, can reduce a staff and work capacity, the grinding process that no longer needs solder and postwelding, eliminated making problems such as weld seam is not full, the weld surface finish is bad in the soldering operation easily, improved quality and efficient, reduced manufacturing cost;
They are two years old, reduce Puttying in the coating process, scraped work capacitys such as red ash and polishing, operation is simplified, saved auxiliary material, also eliminated overlapping part because of the quality problems such as the bad grey scar that occurs, sand holes of polishing, improved the disposable qualification rate of product, reduced cost, and its appearance is good.
Adopt technical scheme of the present invention, operation is simplified greatly, and quality is easy to control, and it is about 8% that the disposable qualification rate of product has improved, and single vehicle cost decreases.

The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Lap joint process between auto body two exterior skins of the present invention, the overlapping part between two exterior skins adopt welding and coating process successively, in the welding sequence, are that the overlapping part between two exterior skins carries out spot welding; In the coating process, be behind the electrophoretic primer lapped seam between two exterior skins to be carried out injecting glue and received the glue processing, entering the surface lacquer operation with whole body assembly then.This invented technology particularly can be extensive use of in the lap joint process between vehicle body two exterior skins of mini van or baby car at automobile, only lifts two examples below and is illustrated.
Embodiment 1:
As shown in Figure 1 and Figure 2, technology of the present invention is used for the overlap joint between automobile A column exterior skin 1 and the top cover 2, adopts welding and coating process successively at overlapping part, wherein:
In the welding sequence, be that two side flangings 3 of overlapping part carry out spot welding between A column exterior skin 1 and top cover 2, soldering and polishing in the cancellation traditional handicraft, just replaced soldering with spot welding, therefore on this station, no longer use argon welder with point welder, no longer need the polishing of solder and postwelding, can reduce a staff and work capacity, eliminated and made problems such as weld seam is not full, the weld surface finish is bad in the soldering processes easily, quality and efficient have been improved, reduced manufacturing cost, the bullet among the figure is illustrated as weld nugget;
In the coating process, be behind the electrophoretic primer lapped seam between A column exterior skin 1 and the top cover 24 to be carried out injecting glue and received the glue processing, cancel the Puttying in the traditional handicraft, scraped operations such as red ash and polishing, operation is simplified, and has saved auxiliary material, has also eliminated overlapping part between A column exterior skin 1 and the top cover 2 because of quality problems such as the grey scar of the bad appearance of polishing, sand holes, improved the disposable qualification rate of product, reduced cost, and its appearance is good, by users are accepted.
A column exterior skin 1 adopts above-mentioned technology with top cover 2, and operation is simplified greatly, and efficient obviously improves, and cost decreases.
Embodiment 2:
As Fig. 3, Fig. 4, shown in Figure 5, technology of the present invention is used for being connected between the section 6,7 before and after automobile threshold exterior skin hypomere 5 and the gusset exterior skin, adopts welding and coating process successively at overlapping part, wherein:
In the welding sequence, be to carry out spot welding in the lap-joint between the section 6,7 before and after middle threshold exterior skin hypomere 5 and the gusset exterior skin, soldering and polishing in the cancellation traditional handicraft, just replaced soldering with spot welding, therefore on this station, no longer use argon welder with point welder, no longer need the polishing of solder and postwelding, can reduce a staff and work capacity, eliminated and made problems such as weld seam is not full, the weld surface finish is bad in the soldering processes easily, quality and efficient have been improved, reduced manufacturing cost, the bullet among the figure is illustrated as weld nugget;
In the coating process, be to carry out injecting glue and receive the glue processing in the lapped seam between the section 6,7 before and after centering threshold exterior skin hypomere 5 and the gusset exterior skin behind the electrophoretic primer, cancel the Puttying in the traditional handicraft, scraped operations such as red ash and polishing, operation is simplified, saved auxiliary material, also eliminated the overlapping part between the section 6,7 before and after middle threshold exterior skin hypomere 5 and the gusset exterior skin because of quality problems such as the grey scar of the bad appearance of polishing, sand holes, improved the disposable qualification rate of product, reduced cost, and its appearance is good, by users are accepted.
If on vehicle body, only technical scheme of the present invention is adopted at the position among above-mentioned two embodiment, after being followed the tracks of statistical analysis, 100 sample cars find that it is about 8% that the disposable qualification rate of product has improved, single vehicle cost also decreases.
