Problems solved by technology

[0003] The manufacturing process of pure electric vehicles is significantly different from that of traditional cars. The manufacturing process of traditional cars has been improved for nearly a hundred years and has become relatively mature. However, pure electric vehicles are new products, and there are complex and unreasonable layouts in terms of component layout and manufacturing process. and other issues, thus seriously affecting the manufacturing efficiency of pure electric vehicles

Embodiment Construction

[0023] A pure electric vehicle manufacturing process, the complete machine manufacturing process is as follows:

[0024] a) Skeleton blanking;

[0025] b) Assembly of the front and rear wall assembly; the assembly of the front and rear wall assembly adopts the integral molding process of FRP skin and skeleton, and the skin is directly stretched and welded on the main line. The overall structure is simple, elegant, delicate and fine;

[0026] c) Prefabrication of doors; after prefabrication of doors, anti-rust treatment of sandblasting and phosphating is required;

[0027] d) Assembling and welding of skeleton components;

[0028] e) Tailored welding for final assembly; after tailoring and welding for final assembly, it is necessary to carry out anti-rust treatment on the skeleton assembly by sandblasting and phosphating;

[0029] f) Combined packaging of categories;

[0030] g) electrical assembly;

[0031] h) Chassis assembly assembly, chassis wiring harness laying;

Abstract

The invention relates to an overall manufacturing process for a pure electric vehicle. The overall manufacturing process comprises: a) skeleton feeding; b) assembly of a front circumference assembly and a rear circumference assembly; c) door prefabrication; d) installing and welding of skeleton components; e) general assembly and welding; f) door assembly; g) electrical assembly; h) assembly of a chassis assembly and layout of chassis harnesses; i) interior and exterior decoration; j) maintenance, assembly and commissioning; k) coating; and l) inspection and warehousing and other procedures. The overall manufacturing process has the beneficial effects that the overall manufacturing efficiency is improved due to the reasonable process, and the reasonableness, technology, reliability, operability and maintainability of the overall structure are enhanced.

Description

technical field [0001] The invention relates to an automobile manufacturing process, in particular to a pure electric vehicle manufacturing process. Background technique [0002] Pure electric vehicles are a new generation of automotive products developed on the basis of new energy vehicles on the basis of traditional vehicles, and have a strong relationship with traditional vehicles. The body structure of pure electric vehicles adopts the common vehicle platform to ensure the serialization and generalization of products. This model still uses the rectangular tube body frame of the load-bearing truss structure, the side skin adopts prestressed tension skin, the integral front and rear walls, the frame and the overall glass fiber reinforced plastic skin adopt the bonding structure, and all the glass also adopts the bonding structure. Between the skin and the side wall, between the floor and the underframe, the sealant is combined with the foaming treatment of the whole vehic...
